Objective:To explore the surgical efficacy of high position dacryocystorhinostomy (DCR) under nasal endoscopy in patients with chronic dacryocystitis secondary to failure of nasolacrimal duct stent implantation.Methods:A total of 101 patients with chronic dacryocystitis who were treated at People′s Hospital of Peking University from 2013 to 2024 were retrospectively selected, including 14 males and 87 females, aged (56.82±13.00) years (Mean±SD). The patients were divided into control group (53 cases, 59 eyes) and stent group (48 cases, 60 eyes). The control group consisted of randomly selected patients with simple dacryocystitis, while, the stent group included patients with secondary dacryocystitis after failure of nasolacrimal duct stent implantation. All patients underwent endoscopic high DCR with exposed the Rosenmüller valve, combined with intraoperative lacrimal silicone tube implantation. After the operation, the surgical efficacy was evaluated by methods such as Munk score, endoscopic observation of intranasal ostia, lacrimal duct irrigation, and fluorescein test. SPSS 27.0 software was used for data statistics.Results:All 101 patients were followed up for at least one year after DCR surgery. In the control group, one patient (two eyes) was lost to follow-up; while, in the stent group, three patients (three eyes) were lost to follow-up, with one case diagnosed with lacrimal sac cancer. Excluding the lost-to-follow-up cases and the patient with lacrimal sac cancer, anatomical success was achieved in 54 eyes (96.4%, 54/56) in the stent group, and both anatomical and functional success in 53 eyes (94.6%, 53/56); in the control group, 55 eyes (96.5%, 55/57) achieved both anatomical and functional success. No statistically significant difference was found in postoperative effectiveness efficacy between the two groups ( χ2=0.000, P=0.984). Conclusion:For patients with secondary dacryocystitis after nasolacrimal duct stent implantation, high position DCR with exposure of Rosenmüller valve combined with lacrimal duct silicone intubation can achieve better long-term efficacy.

Background: PTSD (Post-traumatic stress disorder, PTSD) had a great impact on health care workers during the COVID-19 (Corona Virus Disease 2019, COVID-19). Better knowledge of the prevalence of PTSD and its risk factors is a major public health problem. This study was conducted to assess the prevalence and important risk factors of PTSD among medical staff during the COVID-19. Methods: The databases were searched for studies published during the COVID-19, and a PRISMA (preferred reporting items for systematic review and meta-analysis) compliant systematic review (PROSPERO-CRD 42021278970) was carried out to identify articles from multiple databases reporting the prevalence of PTSD outcomes among medical staff. Proportion random effect analysis, I2 statistic, quality assessment, subgroup analysis, and sensitivity analysis were carried out. Results: A total of 28 cross-sectional studies and the PTSD results of doctors and nurses were summarized from 14 and 27 studies: the prevalences were 31% (95% CI [confidence interval, CI]: 21%–40%) and 38% (95% CI: 30%–45%) in doctors and nurses, respectively. The results also showed seven risks (p < 0.05): long working hours, isolation wards, COVID-19 symptoms, nurses, women, fear of infection, and pre-existing mental illness. Two factors were of borderline significance: higher professional titles and married. Conclusion Health care workers have a higher prevalence of PTSD during COVID-19. Health departments should provide targeted preventive measures for medical staff away from PTSD.Previous arti

Gallbladder abdominal wall fistula is usually due to the acute cholecystitis with-out timely treatment, which leads the formation of abscess around the gallbladder, the gallbladder adhering to the abdominal wall and the abscess infiltrating into the skin to form a spontaneous abdominal wall fistula. Patient with gallbladder abdominal wall fistula may have the symptoms of cholecystolithiasis and acute cholecystitis. Ultrasound examination can detect the situation of gallbladder conveniently, including the internal echo after formation of abscess, the connection between the gallbladder and abdominal cavity, and the blood flow signal, to clarify the diagnosis for the subsequent treatment. The authors share the diagnosis and treatment experiences of an elderly patient with gallbladder abdominal wall fistula.

Objective: To explore the characteristics and influencing factors of unintentional burns among left-behind children in rural areas of northern Guizhou, from the perspective of parents and children, to formulate strategies to prevent children from burns. Methods: A total of 508 left-behind children were recruited by using a multistage cluster sampling method, and 196 left-behind children’s families were also investigated with a self-designed questionnaire.The relative factors of burns were analyzed by unconditional logistic regression and multiple regression analysis. Results: The report rate of burns among left-behind children was 12.20%(62/508). Left-behind girls were a risk factor for burns(OR=1.81). The time of employment >5 years and the higher of the score of burn-related knowledge were the protective factors(OR=0.23, 0.38)(P<0.05). Only 64.80% of left-behind children’s main guardians had a burns-related knowledge score of 60 or more. The age of their main guardian, the number of minor children, and whether understand of unintentional injury were the influencing factors of burns score. Conclusion The report rate of burns among left-behind children in rural areas in northern Guizhou is still high; parents/guardians have a low cognition level of burns. The knowledge of burns should be strengthened and left-behind children should be cared to reduce the incidence of burns.

Objective To observe the therapeutic effect of Shenqi Fuzheng injection combined with EP chemotherapy in the treatment of non small cell lung cancer (NSCLC),and to improve the quality of life and side effects.Methods 60 cases of NSCLC were randomly divided into observation group and control group,30 cases in each group.The two groups were treated with EP,the observation group was treated with Shenqi Fuzheng injection for two courses.The life quality and adverse effects were observed.Results The quality of life of the two groups after treatment was compared,the difference was statistically significant (93.3% vs 70.0%,χ2 =2.83,P <0.05),the quality of life in the observation group was significantly higher than that in the control group.The white blood cell reduction,anemia and liver and kidney function damage between the two groups had statistically significant differences (P =0.011,0.025,0.016),the adverse reaction of the observation group was less than the control group.Conclusion Shenqi Fuzheng injection combined with EP regimen in the treatment of NSCLC can protect bone marrow hematopoietic function and improve the quality of life of patients with NSCLC chemotherapy.It can be used as one mean of Chinese and western treatment for patients with NSCLC in clinical application.

BACKGROUND: Therapeutic methods for of peripheral facial nerve injury include surgery, physical therapy and drug treatment, but the treatment effect is not ideal in some certain cases. OBJECTIVE: To study the effect of autologous platelet rich plasma on repair of facial nerve injury. METHODS: The bilateral destroyed buccal nerve branches of the 10 white rabbits were put in silica gel nerve regeneration chamber, one side injected with platelet rich plasma as experimental group, the other side injected with normal saline as control group. The general observation, neuroelectrophysiology detection, histological observation, image analysis and evaluation of facial nerve regeneration recovery were performed at 8 weeks after surgery. RESULTS AND CONCLUSION: The action potential latency of the orbicularis oris at the experimental side was significantly lower than that at the control side, and the action potential amplitude (M wave) of compound nerve muscle of the experimental side was significantly higher than that of the control side (P < 0.01). Compared with the control side, the regenerative nerves of the experimental side were more mature with more regenerative axons, and the differentiation of myelin sheath was more mature and the thickness of myelin sheath was wel -distributed. Meanwhile, the diameters of axons were closed to the normal diameter, and the nerve axons were more intensive and arranged more regularly, the outer membrane of nerve fiber was thicker and the col agen fiber and elastic fiber layer were increased when compared with the control group. The number of regenerative axons of the control side was less, and the axons were distributed irregularly and poorly developed, and a large number of fibrous connective tissues were observed. The vacuolar degeneration at the control side was more than the experimental side. The regenerated nerve in the experimental side was better than the control side in the diameter of myelinated axon, area, myelin sheath thickness and axon count, and there were significant differences between two groups (P < 0.01). It indicates that platelet rich plasma has a promoting effect in the repair and regeneration of facial nerve.
