OBJECTIVE: To discuss the clinical features, diagnosis and endoscopic surgical intervention for small steoma of nasal sinuses causing nasal and facial pain. METHOD: A retrospective review was performed on 21 patients with nasal and facial pain caused by small osteoma of nasal sinuses, and nasal endoscopic surgery was included in the treatment of all cases. RESULT: The nasal and facial pain of all the patients was relieved. Except for one ase exhibiting periorbital bruise after operation, the other patients showed no postoperative complications. CONCLUSION Nasal and facial pain caused by small osteoma of nasal sinuses was clinically rare, mostly due to the neuropathic pain of nose and face caused by local compression resulting from the expansion of osteoma. Early diagnosis and operative treatment can significantly relieve nasal and facial pain.

Objective: To understand the characteristics of sexual partners and the influence of having multiple sexual partners on substance use among young male students man who have sex with men (MSM) in China, and to provide scientific basis for the prevention and control of HIV/AIDS among young MSM students. Methods: A mixed recruitment method of snowball sampling and respondent driven sampling was used to recruit young MSM students in Beijing and Tianjin, and a questionnaire survey was conducted among 220 participants from November to December 2019. Chi-square test and generalized linear model multi-factor Logistic regression were used to analyze the influencing factors of substance use before sexual behavior. Results: The average age of them was (22.39±2.57) years old, 84.5% of them were students, the average age of first sexual behavior was (18.83±2.45) years old, 44.1% of them had two or more sexual partners (including fixed sexual partners, temporary sexual partners and commercial sexual partners), 22.7% had more than one male fixed partner. After adjusting for age and education, having multiple sexual partners was risk factor for drinking alcohol before sex (aOR=2.97) or substance abuse (aOR=2.39). Having male temporary sexual partner was an risk factor in substance use before sexual behavior(OR=4.10). Conclusion The characteristics of sexual partners among young MSM students are complex, and the proportion of multiple sexual partners is high. Having fixed single sexual partner can reduce the risk of substance use before sexual behavior. AIDS prevention education for young MSM students should be further strengthened.

Objective:To observe the clinical effect of hormone replacement therapy(HRT) on patients with cervical squamous cell carcinoma after operation and its effect on sex hormone, blood fat, bone content and tumor markers, and to evaluate the clinical significance of HRT therapy.Methods:From January 2016 to January 2019, a total of 100 patients with cervical squamous cell carcinoma admitted to Zhuhai Maternal and Child Health Hospital were analyzed retrospectively.After surgical treatment, 50 patients were willing to receive hormone replacement therapy as the experimental group and 50 patients received routine treatment as the control group, Kupperma score was used to evaluate the severity of perimenopausal symptoms, and the serum levels of sex hormones, blood fat, bone content and tumor markers in the two groups before and after treatment were detected and the occurrence of adverse reactions were evaluated.Results:Before treatment, there was no significant difference in kupperma score, estradiol, follicle-stimulating hormone, luteinizing hormone level, lipid level, bone content and tumor marker level between the two groups(all P>0.05). After HRT treatment, kupperma score in the experimental group was significantly lower than that before treatment((11.47±5.12) vs.(20.46±7.52), t=7.262). In the detection of sex hormones, the levels of estradiol in the experimental group was significantly increased((39.26±7.43) ng/L vs.(13.78±7.52) ng/L, t=12.345), and the levels of follicle stimulating hormone((34.25±7.61) U/L vs.(62.18±19.12) U/L, t=8.245)and luteinizing hormone((20.31±6.25) U/L vs.(35.08±6.27) U/L, t=5.452, P=0.004) in the experimental group were significantly decreased.In the detection of blood lipid level, bone content and tumor markers, high-density lipoprotein((1.62±0.33) mmol/L vs(1.34±0.26) mmol/L, t=4.592, P=0.008) and alkaline phosphatase levels((66.21±25.75) U/L vs.(46.88±9.06) U/L, t=5.912, P=0.001)was significantly increased, the low density lipoprotein((2.78±0.43) mmol/L vs.(2.87±0.78) mmol/L, t=4.265, P=0.012)and total cholestenone((4.02±0.45) mmol/L vs.(4.23±0.91) mmol/L, t=5.761, P=0.002) levels were significantly decreased in the experimental group, with statistically significant differences(all P<0.05). There was no significant difference in the level of serum SCC antigen between the experimental group and the control group before and after treatment ( P> 0.05); there was no significant difference in the above indicators between the experimental group and the control group before and after treatment ( P> 0.05); there was no significant increase in adverse reactions such as breast swelling and pain (3 cases), body mass increase (2 cases), bleeding (1 case), body pain (4 cases), vomiting (4 cases), etc. between the experimental group and the control group (2, 1, 2, 3, 1 case) There was no statistical significance ( P> 0.05). Conclusion:HRT treatment of cervical squamous cell carcinoma patients after surgery can significantly improve the peri menstrual syndrome caused by low estrogen level, and did not significantly increase the risk of recurrence of cervical cancer patients and adverse reactions.

Non-small cell lung cancer(NSCLC)is one of the malignant tumors with high morbidity and mortality worldwide.Ferroptosis is a new type of programmed cell death caused by abnormal accumulation of iron-dependent reactive oxygen species(ROS)leading to lipid peroxidation.It involves the balance between iron metabolism,lipid metabolism,oxy-gen free radical reaction and lipid peroxidation.Recent studies have found that ferroptosis is closely related to the occurrence and development of NSCLC.Due to the emergence of chemotherapy resistance and radiotherapy resistance in the treatment of NSCLC,there is an urgent need to develop new effective drugs and treatment strategies.Traditional Chinese medicine has unique advantages in the prevention and treatment of NSCLC due to its multi-targets and minimal side effects.In this review,we summarize the mechanism of ferroptosis in NSCLC,and discuss the research status of active ingredients of traditional Chinese medicine,single-herb traditional Chinese medicine and Chinese herbal compounds in the intervention of NSCLC through ferroptosis,in order to provide a new theoretical basis for the research of ferroptosis pathway and the prevention and treatment of NSCLC by targeted ferroptosis of traditional Chinese medicine.

Objective:To evaluate the effect of the comprehensive reforms of clinic-pharmacy separation and medical-consumables expenditure linkage in Beijing.Methods:Monitoring data of the comprehensive reforms were collected from 363 public medical institutions in Beijing between January 2016 and December 2019, while descriptive analysis and interrupted times series analysis using segmented regression models were adopted to analyze the influence of the two reforms on medical expense and its structure. We also studied the impact mechanism of service utilization and service price factors on medical expense control.Results:During the period from 2016 to 2019, the medical expenditure of public medical institutions in Beijing increased steadily at an annual growth rate of 4.4%-7.2%. The proportion of drug expense decreased from 44.6% in 2016 to 34.6% in 2019, while the proportion of medical service expense rose from 15.6% in 2016 to 24.3% in 2019, the proportion of examination and laboratory test expenses respectively showed a significant decline in April 2017 and June 2019. These two months witnessed respectively the launch of the two comprehensive reforms. Service utilization played an important role in controlling outpatient and emergency expenses, and service price was the key factor for controlling inpatient expenditure.Conclusions:The implementation of the two reforms in Beijing has effectively curbed the unreasonable growth of medical expenditure, and the expense structure has been constantly optimized and labor value of medical staff gradually improved.
