Objective To explore the distributions of genotypes of HPV infection in CIN and cervical carcinoma. Methods Cervical exfoliated cells were collected from 365 patients with abnormal cervical histology , and subjected to genotyping assay. Results The most prevalent HPV types were 16, 18,52, 58 and 33. The prevalence ratio of HPV 33,52,58 was signi cantly lower in squamous cell carcinoma. Multiple infections decreased from CIN II/III to cervical cancer. Conclusion Besides HPV 16/18, the 52/58/33 subtypes are also important in the development of cervical cancer.

Objective To explore the role of androgen receptor (AR) and estrogen receptor (ER) on male pattern baldness (MPB). Methods The contents of AR and ER in donor and recipient sites of scalps after hair autografting were determinated in 13 cases of MPB. Fluorescent steroid hormone conjugate technique was employed in this study. Results There was no statistical difference in the contents of AR and ER between donor site and grafted scalps in recipient site. Conclusion After the donor tissues are transplanted to the recipient site (the former baldness site), there is no change in contents of AR and ER. The abnormal change of the content of AR and ER in scalp plays an important role in MPB development.

Objective To investigate the protective effect of icariin against varicocele-induced damage on rat epididymis. Methods Forty adolescent male SD rats were randomly divided into control group (n=10), experimental varicocele (EV) group (n=15), icariin (ICA) therapy group (n=15). Experimental varicocele model in the EV group and ICA group was established. The EV was induced by partial ligation of the left renal vein. The rats in the control group underwent a sham operation that separated the spermatic vessels without ligation. Each rat in the control group and EV group was lavaged with 2 mL physiological saline every day for 6 weeks. Each rat in the ICA group was lavaged with icariin [100 mg/(kg·d)] for 6 weeks. Rats in all groups were executed after 6 weeks. The contents of sialic acid were measured by spectrophotometry. Carnitine concentrations were measured by DTNB. HE stain was used to observe the microstructure changes in the epididymal tissue. Electron microscopy was used for observing the ultrastructural changes of the epididymis. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) method was used to detect the apoptosis of the epididymal epithelium. Results Compared with the control group, the microstructure and ultrastructure of the epididymis in EV group showed pathological damage. Compared with the EV group, the damage of the epididymal microstructure and ultrastructure significantly alleviated. Apoptosis index (AI) of epididymal epithelium in the EV group was significantly higher than that in the control group (P<0.01). However, AI of epididymal epithelium in the ICA group was significantly lower than that in the EV group (P < 0.01). The sialic acid and carnitine concentrations of the epididymis in the EV group was significantly lower than that in the control group (P < 0.01), respectively. However, the sialic acid and carnitine concentrations of the epididymis in the ICA group was significantly higher than that in the EV group (P < 0.01), respectively. Conclusion This study indicates that varicocele could result in the apoptosis of epididymal epithelium and icariin decreased the varicocele-induced apoptosis , suggesting that varicocele could damage the structure and function of epididymis, which can be repaired by icariin.

Objective:To determine the prevalence of sarcopenia and explore related influencing factors of sarcopenia in maintenance hemodialysis (MHD) patients.Methods:MHD patients aged ≥18 years old and receiving therapies of ≥3 months from March 2019 to December 2019 in Blood Purification Centre of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively enrolled in this study. General data of the patients were collected. Grip strength was measured by the Jamar dynamometer and the chair stand was measured by a chair of standard height to assess skeletal muscle strength and appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry. Baseline data between MHD patients with and without myasthenia were compared. Logistic regression analysis method was used to analyze the influencing factors for sarcopenia in MHD patients.Results:A total of 125 MHD patients were enrolled, with 68 males (54.4%), age of (59.4±14.9) years and median dialysis age of 51.0(23.5, 101.0) months. Sarcopenia was diagnosed in 39 cases (31.2%). Compared with MHD patients without sarcopenia, age, tumor necrosis factor-α, von Willebrand factor (vWF) and proportion of using α ketones were higher, and serum carbondioxide combining power (CO 2CP), prealbumin, albumin and proportion of regular exercise were lower in MHD patients with sarcopenia (all P<0.05). Multivariable logistic regression analysis results showed that low CO 2CP ( OR=0.717, 95% CI 0.576-0.892, P=0.003), high vWF ( OR=1.037, 95% CI 1.016-1.058, P<0.001) and no regular exercise ( OR=0.309, 95% CI 0.118-0.810, P=0.017) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia in MHD patients is high. Low CO 2CP, high vWF and no regular exercise are independent influencing factors for sarcopenia in MHD patients.

Objective:To establish a diagnostic system for heat toxin syndrome of acute cere-bral infarction.Based on this toxin syndrome diagnostic system,the general principles of heat toxin development will be uncovered,and the critical turning point at which the heat toxin syndrome occurs will also be explored.Methods:In this study,a total of 271 hypertension patients with cerebral infarction within 72 h were recruited from the Affiliated Dongfang Hospital of the Beijing University of Chinese Med-icine,the Affiliated Dongzhimen Hospital of Beijing University of Chinese Medicine,the Affil-iated Renmin Hospital of Peking University,the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine,the Affiliated Hospital of Shandong University of Traditional Chinese Medicine,the Affiliated Hospital of Changchun University of Traditional Chinese Medicine,the Affiliated Hospital of Hebei University of Traditional Chinese Medicine and China Meitan General Hospital from August,2008,to December,2009.The patients' Chi-nese medical information was recorded on days 1,3,5,7,and 14 during their hospitalizations.The medical records were recorded according to traditional Chinese medicine (TCM) theory and included the serum marker levels at the beginning and at the end of the trial.The time line was also analyzed.Results:The level of Hs-CRP,PAG,NSE,OX-LDL,and MMP-9 were abnormal and,were higher in CI patients compared to hypertension patients.In the study of the heat toxin diagnosis system,according to the entropy clustering results,30 combinations of the medical information can be sorted into the traditional syndromes,but 13 combinations cannot be sorted.To obtain more precise symptoms related to the heat toxins,a logistic regression equation was set up with the variables from the unsorted medical information;the dependent variables were fever and BP fluctuation.Weighted variables were obtained.MLP analysis demonstrated that the diagnosis model was stable and precise.The accuracy reached 83.82％.The ROC test showed that seven points of the diagnosis system was the best cutting point,with a sensitivity of 0.857 and a spec-ificity of 0.955.Progressing stroke was related to heat toxin syndrome.When the turning point appeared,the combination of symptoms,such as coma,aphasia,gummy eyes,and halitosis,predicted the deterioration or recovery of Cl.The heat toxin syndrome existed in every sub-type of Cl;however,the observed heat toxin levels were highest in PACl and lowest in LACl.Meanwhile,blood and sputum stasis syndromes transformed into heat toxicity were one source of heat toxin syndrome.Conclusion:Heat toxin syndrome,as well as qi/blood/sputum stasis,co-existed in the CI pa-tients,and the transformation frequently appeared during the process.Three to five days after the onset of Cl was the turning point,at which time several combinations of medical indicators make it possible to predict the development of Cl.
