The sun is shining in the sky, and the waves are surging. A medical ship plowed a silver track on the blue sea, heading towards a distant reef. On the deck, a female military doctor gazed at the junction of the sea and sky, thin but radiant. She couldn't remember how many times she had traveled to the islands and reefs for inspection like this. From a specially recruited military doctor to a respiratory disease expert, and then to a pioneer in clinical tropical medicine in the entire army, her visits have covered islands and reefs in the South China Sea, treating tens of thousands of officers and soldiers. She led the team to establish the first clinical tropical medicine discipline in the entire army, dedicated to safeguarding the lives and health of island soldiers and the people. She is Li Huiling, the director of the Department of Tropical Medicine at Hainan Hospital of the People's Liberation Army General Hospital, a "health guardian" who wrote miracles of life on the thousands of miles of the sea. Determination - "Soldiers are strong, but life needs to be guarded". Having served on warships, patrol posts, on islands and reefs, and in jungles for more than ten years, Li Huiling has gradually grown from a local doctor to a leading figure in key military disciplines. What kind of life transformation has Li Huiling completed? During high school, Li Huiling had a great passion for literature. Her prose has a fresh language and delicate brushstrokes, and is often used as a model for everyone to learn. Li Huiling's father is an agricultural hydraulic engineer. When at home, the warmest time for the father and daughter is when they each occupy their own space in the study, one studying hydraulic drawings and the other savoring literary classics. The air is filled with a strong fragrance of books and family affection. At the age of 16, my father fell ill from overwork and was diagnosed with advanced gastric cancer. Despite suffering from illness, my father always says that his biggest regret is not being able to use the knowledge he has learned to benefit his fellow villagers. At the final moment of the countdown to life, Li Huiling's father instructed him, "Literature can nourish the soul, but medicine can save lives. Go study medicine and help those who contribute to the country!" Li Huiling remembered his father's advice. After abandoning literature and pursuing science, Li Huiling was admitted to a medical university with excellent grades and embarked on the path of medicine. In the quiet laboratory at night, she carefully traced the human anatomy map; On the playground with a slight dew in the morning, she ran while memorizing pharmacological knowledge... With this persistence, at the age of 33, she entered the Guangzhou Institute of Respiratory Diseases at Guangzhou Medical University as a postdoctoral fellow in the Department of Respiratory Medicine. Two years later, due to her abundant research achievements, she stayed on campus to work. That year, the Hainan Hospital of the People's Liberation Army General Hospital was established and urgently needed a large number of professional talents. Upon learning the news, Li Huiling, who had already made a name for herself in the research institute, proposed the idea of working in a military hospital to her leaders. Her mentor and colleagues advised her to think twice, but when she thought of her father's advice, she resolutely packed her bags, crossed the Qiongzhou Strait, and joined the Hainan Hospital of the People's Liberation Army General Hospital as a hired doctor. Later, due to her outstanding professional abilities, she was specially recruited into the army. Not long after being conscripted into the military, Li Huiling received an important lesson in her military career - going to Zhurihe Training Base to serve and train. At the age of 40, she lived and trained alongside young soldiers, enduring numerous challenges on the training ground. The first time I rode in a tank, watching young soldiers control the tank in the turbulence, I truly understood what 'golden spear and iron horse' were and what 'smoke of gunpowder' was, "Li Huiling recalled. On the day of the live fire shooting, Li Huiling personally experienced the shock of the shell being fired: a huge deafening sound. She said, 'At that moment, I understood the mission that soldiers shoulder.' 'You protect your country, I protect you.'. This is the responsibility of military doctors. ”The military training left Li Huiling with a profound understanding. During a wilderness survival training, a 19-year-old soldier fainted from heatstroke. The first thing he said when he woke up was, "I can still participate in the training!" This fighting spirit of "being lightly injured and unable to leave the front line" deeply moved Li Huiling. Another time, a soldier suddenly fainted during training. Upon hearing the cries for help from his comrades, Li Huiling rushed forward and performed cardiopulmonary resuscitation for the soldiers. After intense rescue efforts, the soldier finally regained consciousness. Afterwards, it was learned that the soldier secretly persisted in high-intensity training despite feeling unwell in preparation for military competitions. Warriors are strong, but life needs to be guarded. ”Li Huiling said that this has further strengthened her determination to become a military "health guardian". In 2019, the Hainan Hospital of the People's Liberation Army General Hospital organized a seminar on discipline construction, entitled 'As long as officers and soldiers need it, I am duty bound'. At that time, the military did not yet have a mature clinical tropical medicine discipline. The hospital is located in a tropical region, and all treatment is done in a tropical environment. There are significant differences in the treatment mode of many diseases compared to temperate regions, and the establishment of a clinical tropical medicine discipline is urgent. Considering Li Huiling's strong professional abilities, the hospital leadership wants her to take the lead in undertaking this task. At that time, Li Huiling was already a key expert in respiratory medicine, while tropical medicine was a completely new field. The difficulties and challenges faced by leading the establishment of the new discipline can be imagined. Li Huiling repeatedly checked the health records of the stationed officers and soldiers on the island to understand the situation. In the archives, she deeply regretted a real case: a soldier suffering from a tropical disease delayed the best treatment opportunity due to the lack of professional treatment conditions on the island... Closing the archives, Li Huiling felt a heavy responsibility on her shoulders. As long as the officers and soldiers need it, I am duty bound. ”After careful consideration, Li Huiling resolutely took on this heavy responsibility and began the "Long March" of establishing a new discipline. Li Huiling started from scratch and embarked on a long journey of research and learning with the perseverance of "pioneering". Her footprints covered more than 50 universities and research institutions. In Guangzhou, she consulted Academician Zhong Nanshan on the diagnosis and treatment of tropical respiratory diseases; In Shanghai, she had in-depth exchanges with experts from the Naval Medical University; In Guangxi, she conducted field research on the front line of border defense... This research journey spanning more than 20 provinces and cities laid a solid foundation for the establishment of a tropical medicine department. At the beginning of the establishment of the Tropical Medicine Department, there was only one office and a few medical staff, facing difficulties such as lack of mature experience and incomplete hardware. Li Huiling led everyone to carefully screen medical equipment and work overtime to write diagnosis and treatment standards. At that time, we didn't even have a decent hospital room. ”The head nurse of the department recalled, 'Director Li took us to a temporary makeshift ward for treatment.' In the summer, the ward was hot and humid, and Li Huiling always had patients wait in air-conditioned rooms, while she herself received treatment in the stuffy 'consultation room'. After the establishment of the department, Li Huiling traveled to more than 20 systematic hospitals within the guarantee area and led medical teams to visit islands and field training sites more than 40 times to collect and sort out the health data of officers and soldiers. She also led the team to carry out solid research on the "Tropical Special Needs Drug Guarantee Mechanism", innovatively established a three-level treatment network, and explored practical and effective experience for discipline construction. Over the course of six years, this department, which started from scratch, gradually developed into a key clinical specialty in the military with dozens of medical staff and advanced medical equipment. The "real-time disease detection system" created by the team in practice won the first prize of the Military Science and Technology Progress Award, and the diagnosis and treatment manual written has become an essential tool for military doctors stationed on the island. Perseverance - "Even if there is a glimmer of hope, I will do my best" in Li Huiling's dictionary, there is no word "give up". In order to save the lives of patients, Li Huiling often races against time and fights with the "Grim Reaper", practicing the oath of "life in trust and never giving up" with practical actions. A few years ago, a soldier named Xiao Tang from a certain naval unit was diagnosed with complex tuberculous pleurisy, with difficulty breathing and severe shortness of breath. Several doctors who received treatment earlier were helpless. Leave it to me. ”Li Huiling's simple yet firm words reignited hope for Xiaotang and his family. Li Huiling led the organization of a multidisciplinary consultation throughout the hospital and proposed a five link anti tuberculosis treatment plan. For over 8 months, she washed Xiao Tang's chest every day and performed 12 chest punctures. After Xiaotang was discharged from the hospital, Li Huiling continued to follow up regularly until he fully recovered. She said, 'Doctors are responsible for every life. Even if there is a glimmer of hope, I will do my best.' The miracle of life also appeared in another elderly patient. This elderly person has been identified by multiple hospitals as having "little hope of survival" due to large areas of phlegm clots blocking both lungs. The elderly's family found Li Huiling with the last glimmer of hope. If you trust me, let me give it a try. ”After obtaining the consent of the family, Li Huiling performed bronchoscopy surgery on the elderly and removed phlegm clots from the patient's respiratory tract. On the second day of the surgery, the old man got out of bed and walked with the help of his family. A doctor treats illness and saves the heart. ”This is a phrase that Li Huiling often says. During ward rounds, she always warms the stethoscope with her palm before touching the patient's skin; She insists on unlimited numbers and strives to ensure that every patient who comes from afar can receive treatment; She stayed in the ward all night to treat critically ill patients, ate a boxed meal when hungry, and rested on the sofa for a moment when she was trapped. For many years, Li Huiling has led medical teams to visit islands and reefs every year. She also organized a team to conduct scientific research and develop specialized protective ointments based on the characteristics of tropical marine environments, effectively solving the health problems that plague officers and soldiers. Director Li is always able to identify small health hazards and provide targeted protective suggestions. ”A company commander of a certain garrison told reporters. In Li Huiling's desk drawer, there are precious thank-you letters from all over the world; On the honor wall of the department, banners sent by grassroots officers and soldiers are hung. What pleased Li Huiling the most were the photos sent by the recovered officers and soldiers: some were lively on the training ground, some had won gold and silver in martial arts competitions, and some had grown into the backbone of the army. Each generation has its own Long March, and each generation has its own responsibilities. ”Looking out at the vast sea outside the window, Li Huiling's gaze was firm, "My Long March is to use medical skills to protect those who protect our motherland
