Objective: To analyze the treatment and prognosis of patients with International Federation of Gynecology and Obstetrics (FIGO) 2018 stage Ⅲc cervical squamous cell carcinoma. Methods: A total of 488 patients at Zhejiang Cancer Hospital between May, 2013 to May, 2015 were enrolled. The clinical characteristics and prognosis were compared according to the treatment mode (surgery combined with postoperative chemoradiotherapy vs radical concurrent chemoradiotherapy). The median follow-up time was (96±12) months ( range time from 84 to 108 months). Results: (1) The data were divided into surgery combined with chemoradiotherapy group (surgery group) and concurrent chemoradiotherapy group (radiotherapy group), including 324 cases in the surgery group and 164 cases in the radiotherapy group. There were significant differences in Eastern Cooperation Oncology Group (ECOG) score, FIGO 2018 stage, large tumors (≥4 cm), total treatment time and total treatment cost between the two groups (all P<0.01). (2) Prognosis: ① for stage Ⅲc1 patients, there were 299 patients in the surgery group with 250 patients survived (83.6%). In the radiotherapy group, 74 patients survived (52.9%). The difference of survival rates between the two groups was statistically significant (P<0.001). For stage Ⅲc2 patients, there were 25 patients in surgery group with 12 patients survived (48.0%). In the radiotherapy group, there were 24 cases, 8 cases survived, the survival rate was 33.3%. There was no significant difference between the two groups (P=0.296). ② For patients with large tumors (≥4 cm) in the surgery group, there were 138 patients in the Ⅲc1 group with 112 patients survived (81.2%); in the radiotherapy group, there were 108 cases with 56 cases survived (51.9%). The difference between the two groups was statistically significant (P<0.001). Large tumors accounted for 46.2% (138/299) vs 77.1% (108/140) in the surgery group and radiotherapy group. The difference between the two groups was statistically significant (P<0.001). Further stratified analysis, a total of 46 patients with large tumors of FIGO 2009 stage Ⅱb in the radiotherapy group were extracted, and the survival rate was 67.4%, there was no significant difference compared with the surgery group (81.2%; P=0.052). ③ Of 126 patients with common iliac lymph node, 83 patients survived, with a survival rate of 65.9% (83/126). In the surgery group, 48 patients survived and 17 died, with a survival rate of 73.8%. In the radiotherapy group, 35 patients survived and 26 died, with a survival rate of 57.4%. There were no significant difference between the two groups (P=0.051). (3) Side effects: the incidence of lymphocysts and intestinal obstruction in the surgery group were higher than those in the radiotherapy group, and the incidence of ureteral obstruction and acute and chronic radiation enteritis were lower than those in the radiotherapy group, and there were statistically significant differences (all P<0.01). Conclusions: For stage Ⅲc1 patients who meet the conditions for surgery, surgery combined with postoperative adjuvant chemoradiotherapy and radical chemoradiotherapy are acceptable treatment methods regardless of pelvic lymph node metastasis (excluding common iliac lymph node metastasis), even if the maximum diameter of the tumor is ≥4 cm. For patients with common iliac lymph node metastasis and stage Ⅲc2, there is no significant difference in the survival rate between the two treatment methods. Based on the duration of treatment and economic considerations, concurrent chemoradiotherapy is recommended for the patients.

To investigate the relationship between male semen parameters and sperm DNA fragment index with age. Adopt cross-sectional sampling survey design, 3 203 male patients who visited the Department of Reproductive Andrology in the Third Affiliated Hospital of Zhengzhou University from January 2019 to June 2021 were selected as subjects. Age range is 18-57 years, with the median age of 30 years. Through quartile regression analysis, the correlation between age and different male semen parameters and DNA fragment index (DFI) was presented. The study population was divided into ≤30 years old group and >30 years old group, and the correlation between age and semen volume, sperm concentration, total sperm count, progressive motility, total motility, percentage of normal sperm and DFI level were compared and analyzed. The results showed that there were significant differences in progressive motility, total motility and DFI level among different age groups (χ²=-4.608, -4.604, -7.719,P all <0.05), but there was no significant difference in semen volume, sperm concentration, total sperm count and percentage of normal sperm (χ²=-1.712, -1.203, -0.149, -0.175,P all >0.05). In the>30 years old age group, there was a very weak negative correlation between male age and semen volume, progressive motility and total motility (r=-0.137, -0.101 and -0.056, P all <0.05). There was a very weak positive correlation between male age and sperm concentration and sperm DFI level (r=0.061, 0.190, P all <0.05), while there was no correlation between male age and total sperm count and percentage of normal sperm (r=-0.018, -0.016,P all >0.05). In conclusion, with the increase of age, especially after the age of 30, semen volume, progressive motility and total motility decreased, while sperm concentration and DFI level increased, and semen quality decreased.

OBJECTIVES: To study the clinical features of children infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: The medical data of 19 children who were diagnosed with SARS-CoV-2 Omicron variant infection from January 28 to March 3, 2022 in Hangzhou were retrospectively reviewed. RESULTS: Among the 19 children, there were 7 boys (37%) and 12 girls (63%), and their age ranged from 6 months to 16 years, with a median age of 2 years and 1 month. Most of these children were infants and young children (aged ≤3 years, accounting for 53%). Among these children, 11 (58%) were unvaccinated with SARS-CoV-2 vaccine and 8 (42%) were vaccinated with SARS-CoV-2 vaccine, and 3 children (16%) had a history of underlying diseases. All 19 children had a clear history of close contact with persons infected with SARS-CoV-2, and 10 children (53%) were involved in the cluster outbreak in a maternal and infant care center. In terms of clinical classification, 13 children (68%) had mild coronavirus disease 2019 (COVID-19) and 6 (32%) had common COVID-19, with no severe cases of COVID-19. The most common clinical symptoms were cough (100%) and fever (63%). The children with a normal peripheral white blood cell count accounted for 84%, and those with a normal lymphocyte count accounted for 68%. There were no significant abnormalities in platelet count, procalcitonin, liver function parameters (alanine aminotransferase and aspartate aminotransferase), and renal function parameters (creatinine and urea). Six children (32%) had obvious signs of pneumonia on chest CT. All 19 children were given symptomatic treatment, and 12 children (63%) were given aerosol inhalation of interferon α. All children were cured and discharged. CONCLUSIONS Children infected with Omicron variant strains are more common in infants and young children, with mild symptoms and good prognosis. Most of the children have a history of close contact with persons infected with SARS-CoV-2, and epidemic prevention and control should be strengthened in places with many infants and children, such as maternal and infant care centers.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective: To observe the changes of liver metabolism in mice exposed to artificial light at night. Methods: Healthy male C57BL/6J mice were randomly divided into the light at night group and the control group, with 8 mice in each group. The daily light/dark cycle was 12/12 hours in the control group, and 24/0 hours in the light at night group for 10 consecutive days. The hepatic metabolite profiles of the two groups of mice were detected by high performance liquid chromatography tandem mass spectrometry. The modelling was assessed by combining principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis ( OPLS-DA ) , The changes of metabolites in the two groups were compared through KEGG database. Results: Compared with the control group, 9 different metabolites were detected in the light at night group, among which the down-regulated metabolites were glycine-betaine, glutathione, tyrosine, betaine, lysine, hypoxanthine, histidine and methionine, and the up-regulated ones were mannose-6-phosphate. The weight analysis of the metabolic pathways showed that the major influences on liver of light at night group were phenylalanine-tyrosine-tryptophan metabolism, tyrosine metabolism, fructose and mannose metabolism, cysteine and methionine metabolism and histidine metabolism. Conclusion The metabolism of various amino acids and sugars in light at night mice is disturbed,and the key differential metabolites are tyrosine, methionine, histidine and mannose-6-phosphate.

Objective: To explore the feasibility of DDD pacemaker implantation under EnSite system guidance with micro X-ray. Methods: DDD pacemaker implantation under EnSite system guidance with micro X-ray was performed in 5 special patients who needed cardiac pacing while should be avoid X-ray exposure. Results: All 5 patients were smoothly finished DDD pacemaker implantation, no wire dislocation or perforation occurred after the operation. The cumulative skin radiation dose was (2.20±0.45) mGy, operative X-ray exposure time was (11.60±2.07) s and the operation time was (58.40±4.04) min. Conclusion: DDD pacemaker implantation under EnSite system guidance with micro X-ray was safe and feasible.

OBJECTIVE To investigate the effects of total flavonoids of bugloss(TFB)on left ventricular (LV)remodeling after myocardial infarction(MI),LV size and function was compared in mice subjected to left anterior descending coronary artery ligation. METHODS 28 d after MI, the infarcted fraction of the LV and LV mass, systolic and diastolic function were measured. Capillary density and myocyte width in the nonischemic portion of the LV were also determined.RESULTS 28 d after MI,both groups had dilated LVs with decreased fractional shortening and lower ejection fractions. Although the infarcted size of the LV was similar in both groups,LV end-diastolic internal diameter,end-diastolic volume,and mass were lower, but fractional shortening, ejection fraction, and the maximum rate of developed LV pressure(dp/dtmax)were greater in TFB treated mice than in control mice.Impairment of diastolic func-tion, as measured by the time constant of isovolumic relaxation (t) and the maximum rate of LV pres-sure decay(dp/dtmin),was more marked in control mice than in TFB treated mice.Mortality after MI was greater in control mice than in TFB treated mice.In control mice,capillary density and myocyte width in the nonischemic portion of the LV did not differ before and 28 days after MI, whereas in TFB treated mice, capillary density increased and myocyte width declined after MI. CONCLUSION These results suggest that the presence of TFB limits LV dysfunction and remodeling in a murine model of MI in part by decreasing myocyte hypertrophy in the remote myocardium.

Objective To screen stroke risks among middle-aged and elderly people in community outpatient clinics in Shanghai.Methods A stroke risk screening was conducted among people aged 45-75 years selected with convenient sampling method from 10 community health service centers in Putuo district,Yangpu district and Pudong New Area of Shanghai during January to July 2017.The questionnaire and clinical measurement were used for screening.Multivariate logistic regression analysis was used to analyze the risk factors in subjects with high stroke risk.Results In this study,1 094 individuals with high stroke risk were screened out from 1 750 participants (62.5％).The proportion of high risk cases was higher among men (66.7％,473/709) than that among women (59.7％,621/1 041),unmarried,divorced or widowed (75.0％,90/120)than married or cohabitants (61.6％,1 004/1 630),living alone (72.1％,70/97) than living with others (61.9％,1 024/1 653) (x5=8.969,8.571,4.081;P＜0.01).Compared with non-high-risk subjects,the high-risk subjects had higher BMI,systolic blood pressure,diastolic blood pressure,fasting blood glucose,glycated hemoglobin,total cholesterol,triglycerides,serum creatinine and homocysteine,and were more likely to have carotid plaques or stenosis,the difference was statistically significant (P＜0.05).Multiple logistic regression analysis showed that unmarried/divorce/widowed,high BMI,systolic blood pressure,fasting blood glucose,total cholesterol,and carotid plaque or stenosis were positively associated with high stroke risk(OR=2.015,1.173,1.013,1.456,1.139,1.026,2.103;P＜0.05).Conclusions The proportion of high stroke risk individuals among middle-aged and elderly people is higher in community general practice outpatient clinics in Shanghai.Patients with high BMI,systolic blood pressure,fasting blood glucose and total cholesterol,and carotid plaque or stenosis,as well as those unmarried/divorced/widower should be the subjects for stroke intervention.
