Abstract: Objective　To evaluate the influence of coronavirus disease 2019 (COVID-19) prevention and control measures on the transmission and epidemic of influenza in Chongqing, so as to provide references for formulating targeted influenza prevention and control strategies. Methods　The influenza surveillance data, during the year 2018 to 2020, were collected through the "China Influenza Surveillance Information System", and the seasonal characteristics of influenza epidemic were analyzed. The percentage of influenza like cases (ILI%) and influenza virus positive rate between 2020 and 2018-2019 were compared, so as to evaluate the impact of COVID-19 prevention and control measures on influenza epidemic characteristics. Results　The annual proportions of ILI cases in Chongqing were respectively 3.53%, 2.23% and 1.2% from 2018 to 2020, while the positive rates of influenza virus were respectively 13.97%, 23.81% and 2.65%. The distribution trend of ILI% from 2018 to 2019 fluctuated were similar, but it continued to drop and remain at a low level since February 2020. The positive rate of influenza virus showed an epidemic peak from December to March in 2018-2019, also peaked from November 2019 to January 2020, but decreased to 0 in March. ILI% was positively correlated with the positive rate of influenza virus (r=0.404 8, P<0.05). In 2020, compared with the same period of 2018-2019, the growth rate of ILI% was -66.09% and -46.32%, respectively. The positive rate of influenza virus in 2020 decreased by 81.03% and 88.87% compared with the same period of 2018-2019, respectively. The growth rates of influenza virus positive rate in January 2020 were decreased with a small rate of about 39.87%, and with a significantly decline of more than 93.65% from February. No influenza epidemic was found after March. Conclusions　Since COVID-19 prevention and control measures were implemented in January 2020 in Chongqing, the ILI% and the positive rate of influenza virus in sentinel hospitals decreased significantly. In the season of high incidence of respiratory infectious diseases, personal protection and other measures can effectively reduce influenza virus infection.

This study examined the incidence, neuropsychological characteristics and risk factors of cognitive impairment 3 months after stroke in China. Five regions that differed in geography and economy in China were selected. Patients from the hospitals located in the five regions were prescreened at admission, and the demographic data, vascular risk factors and clinical characteristics of stroke were obtained. A battery of cognitive-specific domain tests was performed in the patients who failed to pass cognitive screening 3 months post stroke. Patients were diagnosed as having post-stroke cognitive impairment (PSCI) or no cognitive impairment (NCI) based on the results of the neuropsychological tests. Univariate analysis was performed for suspect risk factors, and significant variables were entered in multivariable logistic regression analysis. Our results showed that a total of 633 patients were recruited 3 months after stroke; complete cognitive tests were performed in 577 of the stroke patients. The incidence of PSCI in these Chinese patients was 30.7%. There were 129 (22.4%) patients with visuospatial impairment, 67 (11.6%) with executive impairment, 60 (10.4%) with memory impairment and 18 (3.1%) with attention impairment. The risk factors associated with PSCI were older age (odds ratio [OR] 1.76, 95% confidence interval [CI] 1.20-2.58), low education level (OR 2.45, 95% CI 1.65-3.64), depressive symptom (OR 1.69, 95% CI 1.09-2.61), obesity (OR 2.57, 95% CI 1.41-4.71), stroke severity 3 months post stroke (OR 1.62, 95%CI 1.10-2.37) and cortex lesion (OR 1.55, 95% CI 1.04-2.31). It was concluded that PSCI occurs commonly 3 months after first-ever stroke in Chinese patients. Visuospatial ability may be the most frequently impaired cognitive domain for the patients with stroke. The critical risk factors of PSCI are older age, low education level, depressive symptom, obesity, stroke severity 3 months post stroke and cortex lesion.

Objective:To investigate the clinical significance of bone metabolism indexes and human leukocyte antigen B27 (HLA-B27)in ankylosing spondylitis(AS)and analyze their diagnostic value. Methods:The subjects were 94 cases of AS patients,239 cases with other diseases and 80 healthy controls, and the results were retrospectively surveyed. Results:In the AS group, the concentration of the β-collagen specific sequence (β-CTX ) was higher ( P<0. 05 ) while the concentrations of osteocalcin ( OC ) , 25-hydroxyvitamin D[25-(OH)D] and parathyroid hormone(PTH)were lower than those in the control group. In the AS group,there was a positive correlation between the concentration of C-reactive protein(CRP)and β-CTX(P<0. 01),and the concentration of CRP was negatively correlated with the concentration of 25-(OH)D(P<0. 05). However,the concentrations of other bone metabolic indexes had no correlation with the concentration of CRP(P<0. 05). The positive rate of HLA-B27 in the AS group was significantly higher than that in other groups(P<0. 05),and HLA-B27 had highly sensitive and specific in the diagnosis of AS. In the AS group,the sensitivity of the concentration of 25-( OH) D was higher than β-CTX,while its specificity was lower than β-CTX. Conclusion:Bone metabolic indexes have great value in early screening and clinical diagnosis of AS,especially β-CTX and 25-( OH) D were more obvious.

OBJECTIVETo investigate the pathogenesis and treatment of penile necrosis resulting from microwave diathermy following circumcision.

METHODSWe retrospectively analyzed the clinical data about 9 cases of penile necrosis resulting from postoperative microwave diathermy following circumcision. The 9 males, aged 20 - 39 (mean 26) years, underwent traditional circumcision for redundant prepuce or phimosis in other hospitals, followed by microwave diathermy for 30 - 60 minutes daily, which resulted in penile necrosis. With no response to conservative therapy, the patients were referred to our hospital at 3 -30 days postoperatively. Of the 9 patients, 5 presented with dry gangrene and 4 with moist gangrene. Six of the patients underwent partial penectomy, including 1 that received penis lengthening.3 months later, while the other 3 underwent total penectomy for total penile necrosis followed by penile reconstruction 3 months later, with deep inferior epigastric perforator (DIEP) flaps and by implantation of the 12th costal cartilage in 2 cases and with epigastric groin island flaps and by urethroplasty in the other.

RESULTSThe patients were followed up for 2 - 8 years, and all could urinate smoothly in the standing position. Of the 6 men treated by partial penectomy, 1 received penis lengthening and achieved a penile length of 7 cm and 5 had the remaining penile length of 3 -5 cm, 4 with erectile function and the other 2 capable of sexual intercourse. The 3 men treated by total penectomy achieved nearly normal external appearance of the penis, with a finalized length of (11.7 ± 1.3) cm, a circumference of (11.4 ± 2.1) cm, and a normal feel of the skin. Of the 3 cases of penile reconstruction, 2 achieved sufficient erectile hardness of the penis (grade 3) for sexual intercourse, while the other 1 remained impotent.

CONCLUSIONPost-circumcision microwave diathermy may result in penile necrosis, for the management of which, early debridement is necessitated and penile lengthening or reconstruction can be performed according to the severity of the lesion and needs of the patient.

OBJECTIVETo study the role of programmed cell death 5 (PDCD5) protein in the oncogenesis and development of renal clear cell carcinoma and its association with the prognosis of the malignancy.

METHODSPDCD5 expression was assayed immunohistochemically in 46 cases of human renal clear cell carcinoma, and the patients' survival was followed up.

RESULTSPDCD5 staining in the adjacent normal tissue of the tumor was significantly stronger than that in the tumor tissue, and PDCD5 expression was significantly correlated with the tumor grade, stage and prognosis. The tumors of high grade with strong invasive ability had much less PDCD5 expression and lighter staining. The three- or five-year survival rates of patients positive for PDCD5 expression was much higher than that of patients negative for PDCD5 expression.

CONCLUSIONPDCD5 is a potent inhibitor of malignant transformation of renal clear cell carcinoma and may serve as a major predictor for evaluating the malignant potential and prognosis of the tumor.
