Objective To investigate the age distribution and types of human papillomavirus (HPV) cervical infection in patients in Wuhan region, so as to provide scientific basis for the prevention and treatment of HPV infection and cervical cancer.Methods 9 915 exfoliated cervical cell specimens from patients in Wuhan Medical and Health Center for Women and Children between January 2015 and March 2016 were performed HPV genotyping (21 subtypes), clinical data of 1 732 HPV positive cases were statistically analyzed.Results HPV-positive rates in ≤25, 26~, 36~, 46~, and ≥56 age groups were 22.15%, 15.90%, 17.04%, 19.97%, and 17.57%,respectively (χ2=36.587,P<0.01),HPV-positive rates in ≤25 and 46~ age groups were both higher than other age groups.There were significant differences in single infection and multiple infection rates among different age groups respectively(χ2=14.39, 36.51,respectively, both P<0.05),single infection rate was highest in 46~ and ≤25 age groups (15.41% and 15.24% respectively);multiple infection rates was highest in ≤25 and ≥56 age groups (6.90% and 5.86% respectively).The percentage of single infection and multiple infection were 75.58% and 24.42% respectively, the major single infection type was HPV high-risk subtype (84.34%),the major multiple infection types were high-risk and high-risk compound subtype as well as high-risk and low-risk compound subtype, accounting for 60.52% and 38.77% respectively.The main single infection types were HPV high-risk subtypes 33, 68, 31 and 16, as well as and low-risk subtype 11, the ratios of single infection to multiple infection were 3.13, 2.03, 1.71, 1.67 and 2.00 respectively.Conclusion Cervical infection rates in women in Wuhan region is high in ≤25 and 46~ age groups, there are differences in the distribution of different HPV subtypes of single infection and multiple infection.

To investigate the role of immediate-early gene c-fos in sodium selenite-induced apoptosis and its position in a possible cascade of apoptogenic genes, we compared the time-courses of expression for 5 related genes, including c-fos, during the apop- tosis induced by sodium selenite with or without blockage of c-fos expression by adding c-fos antisense oligodeoxynucleotide ( ASO) in cultured cortical neurons. The results showed that: (1) in control experiments without c-fos ASO adding, 0. 5 μmol/ L sodium selenite-induced apoptosis as revealed by electrophoretic and flow cytometric examinations; at the same time, sodium selenite also induced down-regulation of bcl-2 mRNA expression and up-regulations of mRNAs related to bax, c-fos, p53, and acetylcholinesterase (AChE) genes; (2) in similar experimental conditions with c-fos ASO cotreatment, the sodium selenite-in- duced apoptosis was blocked with the up-regulation of p53 expression still emerging as before, while the changes in expressions of bcl-2, bax, AChE genes were reversed at the same time. The results suggest that c-fos ASO could play a protective role upon cortical neurons from suffering apoptosis induced by sodium selenite, and there might exist a cascade of gene expressions with p53 and c-fos genes being regulated upstream and then bcl-2, bax, and AChE genes being regulated downstream.

Recurrent seizures lead to abnormal expression of synaptic proteins,reorganization of synapse and formation of abnormal neuron network.Recently,it is identified that the synaptic proteins are involved in epileptogenesis.The abnormal expression of several synaptic regulatory proteins and postsynaptic membrane receptor proteins may result in epilepsy.The ion channels usually are the action target of most antiepileptic drugs.However,carbamazepine and zonisamide may interact with syntaxin and/or soluble N-ethylmaleimide-sensitive factor attachment protein receptor complex to exert its function of anti-epilepsy.The synaptic vesicle protein 2A is the action target for new anti-epileptic drugs,including levetiracetam,brivaracetam and seletracetam.

Clinical data of 113 patients with non-alcoholic fat liver disease (NAFLD) diagnosed by liver biopsy from January 2015 to January 2017 in Taizhou People's Hospital were retrospectively reviewed . Patients all underwent transient elastographic ( TE) examination and the values of fat attenuation index (FAI) were obtained.The hepatocyt fatty changes in pathological examination were scored as 0 (＜5%, n＝40), 1 (5%-33%,n ＝27), 2 (34% -66%,n ＝28) and 3 (＞66%, n ＝18).There were significant differences in AST , Glu, TC and FAI among patients with hepatocyte fatty change scores 0, 1, 2 and 3, and the FAI was significantly correlated with the degree of fatty liver disease .The areas under the ROC curve (AUCs) of FAI in patients with hepatocyte fatty change scores 1, 2 and 3 were 0.78, 0.90 and 0.96, respectively.Logistic regression analysis showed that FAI was correlated with TG , TC and BMI.The results suggest that FAI in TE can be a non-invasive, rapid and objective evaluation method for patients with NAFLD.

Objective To investigate the relationship between atrial fibrillation and left heart structure change in patients with hemodialysis combined with hemoperfusion.Methods A total of 60 patients with end-stage renal disease who underwent hemodialysis combined with hemoperfusion treatment in Ganzhou Hospital of Traditional Chinese Medicine from December 2020 to December 2021 were selected.Thirty patients with atrial fibrillation were included in observation group,and thirty patients without atrial fibrillation were included in control group.The left heart structure indexes of two groups were compared,and the relationship between atrial fibrillation and left heart structure change in patients with hemodialysis combined with hemoperfusion was analyzed.Results Left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),left atrium diameter(LAD),interventricular septal thickness(IVST),and left ventricular posterior wall thickness(LVPWT)in observation group were higher than those in control group,and left ventricular ejection fraction(LVEF)was lower than that in control group(P<0.05).Logistic regression analysis showed that the decrease of LVEF and the increase of LVEDD,LVESD,LAD,IVST and LVPWT were associated with atrial fibrillation in patients with hemodialysis combined with hemoperfusion(P<0.05).The results of receiver operating characteristic curve showed that area under the curve of LVEDD,LVESD,LAD,LVEF,IVST and LVPWT in diagnosing atrial fibrillation in patients with hemodialysis combined with hemoperfusion were 0.724,0.708,0.760,0.761,0.762 and 0.758,respectively,which had certain diagnostic value.Conclusion Atrial fibrillation in patients with hemodialysis combined with hemoperfusion is related to the change of left heart structure,and the left heart structure indexes are helpful to assist the diagnosis of atrial fibrillation.

OBJECTIVE3β- hydroxysteroid dehydrogenase deficiency (3βHSD), a rare form of congenital adrenal hyperplasia (CAH) resulted from mutations in the HSD3B2 gene that impair steroidogenesis in both adrenals and gonads. We report clinical features and the results of HSD3B2 gene analysis of a Chinese pubertal girl with salt wasting 3βHSD deficiency.

METHODWe retrospectively reviewed clinical presentations and steroid profiles of the patient diagnosed in Guangzhou Women and Children's Medical Center in 2013. PCR and direct sequencing were used to identify any mutation in the HSD3B2 gene.

RESULTA 13-year-old girl was diagnosed as CAH after birth because of salt-wasting with mild clitorimegaly and then was treated with glucocorticoid replacement. Breast and pubic hair development were normal, and menarche occurred at 12 yr, followed by menstrual bleeding about every 45 days. In the last one year laparoscopic operation and ovariocentesis were performed one after another for recurrent ovary cysts. Under corticoid acetate therapy, ACTH 17.10 pmol/L (normal 0-10.12), testosterone 1.31 nmol/L (normal <0.7), dehydroepiandrosterone sulfate 13.30 µmol/L (normal 0.95 - 11.67), cortisol 720 nmol/L (normal 130-772.8), androstenedione, 17-hydroxyprogesterone and progesterone were normal. Estradiol 461 pmol/L, follicle-stimulating hormone 3.04 IU/L, luteinizing hormone 8.52 IU/L in follicular phase. A pelvic ultrasound showed lateral ovaries cysts (58 mm × 50 mm × 35 mm) and a midcycle-type endometrium. A novel nonsense mutation c.73G >T (p.E25X) was identified in HSD3B2 gene. The girl was homozygous and her mother was heterozygous, while her father was not identified with this mutation.

CONCLUSIONA classic 3βHSD deficiency is characterized by salt wasting and mild virilization in female. Ovary cysts may be the one of features of gonad phenotype indicating ovary 3βHSD deficiency. A novel homozygous mutation c.73G >T(p.E25X) was related to the classical phenotype.

Objective To determine the predictive factors for antiviral therapy in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV) infection [HBeAg(-) CHBI] patients with HBV DNA＜4.3 lg IU/mL.Methods A total of 179 HBeAg (-) CHBI patients were retrospective analyzed.Histology activity index (HAI) and fibrosis (S) were scored according to the Knodell HAI scoring system,and HAI＞3 and/or S≥3 was adopted as indications for treatment.Univariate and multiple regression analysis were used to assess factors associated with treatment indications.Receiver operating curves (ROC) and area under curve (AUC) were used to determine the predictive value of relevant factors.Results There were 81 cases with HAI＞3 (45.3％) and 72 with S≥3 (40.22％),and the proportion of patients with indications for treatment was 54.7 ％.Multiple regression analysis showed that age,γ-glutamyl transpeptadase (γ-GT),platelet (PLT) and albumin (Alb) were the predictive factors for the severity of liver damage and indication for treatment (all P＜0.05).The AUC for age,PLT,γ-GT and Alb were 0.655,0.657,0.726 and 0.65,respectively,and the corresponding Yoden index for age,PLT,γ-GT,and Alb were 0.297,0.426,0.03 and 0.012,respectively,the sensitivities of predicting HBeAg (-CHBI for treatment indications were 0.643,0.842,0.705 and 0.653,respectively.Conclusions This study shows that 54.7％ of HBeAg(-)CHBI patients with HBV DNA＜4.3 lg IU/ml have significant liver histological changes and require antiviral treatment.Older age,higher γ-GT,lower PLT and lower Alb levels are the predictive factors for treatment.

Objective: To explore the relationship between the ratio of dietary vitamin A (VitA) to body weight and hypertension among children, so as to provide a reference for blood pressure control through dietary nutritional interventions and childhood hypertension prevention. Methods: Utilizing the baseline survey and followup sample data from the Healthy Children Cohort established in urban and rural areas of Chongqing from 2014 to 2019, structured quantitative dietary questionnaire and selfdesigned questionnaire were used to investigate the information of dietary intake and socioeconomic characteristics of 15 279 children, as well as blood pressure, height, weight measurement. The ratio of dietary VitA to body weight was divided into four groups based on quartiles [≤P25(Q1), >P25~P50(Q2), >P50~P75(Q3), >P75(Q4)]. Generalized linear regression models and Logistic regression models were used to analyze the correlation between ratio of dietary VitA to body weight with blood pressure levels and prevalence of hypertension. Results: The results of the 2014 baseline survey indicated that, after adjusting for confounding factors such as demographic indicators and nutritional intake, significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) among different groups categorized by the ratio of dietary VitA to body weight (F=157.57, 44.71, 95.92, P<0.01). The baseline ratio of dietary VitA to body weight in children exhibited a negative correlation with DBP, SBP and MAP at baseline and in 2019[baseline: β(95%CI)=-0.65(-0.89--0.42), -0.22(-0.42--0.01), -0.36(-0.56--0.16); 2019: β(95%CI)=-0.77(-1.34--0.19), -0.62(-1.21--0.02), -0.77(-1.34--0.19), P＜0.05]. Compared to Q1 group, the risk of hypertension decreased among children in Q4 at baseline and followup in 2019 [OR(95%CI)=0.63(0.49-0.81), 0.18(0.08-0.42), P<0.01]. Conclusions The ratio of dietary VitA to body weight is significantly negatively correlated with blood pressure levels among children, and dietary VitA deficiency is an independent risk factor for hypertension among children. Measures should be taken to actively adjust childrens dietary nutrition and reduce the risk of childhood hypertension.

Objective To explore the application value of ultrasound-guided use of bupivacaine for subarachnoid block in hip replacement surgery for elderly femoral neck fractures.Methods A total of 108 elderly patients who underwent hip replacement surgery at Ganzhou Traditional Chinese Medicine Hospital from March 2020 to March 2022 were selected as the study subjects.They were divided into conventional anesthesia group and ultrasound guided anesthesia group by means of random number table,54 cases in each group.Patients in the conventional anesthesia group received routine general anesthesia;Patients in the ultrasound guided anesthesia group received unilateral lumbar anesthesia with bupivacaine under ultrasound-guided guidance.Compare the effectiveness of two anesthesia methods during surgery.Results Compared with the conventional anesthesia group,the anesthesia effect of the ultrasound guided anesthesia group was better(P<0.05);The surgery time,amount of bleeding during surgery,postoperative recovery time,and length of hospital stay in the ultrasound guided anesthesia group were all lower than those in the conventional anesthesia group(P<0.05).The ultrasound guided anesthesia group performed better in terms of hemodynamic stability,with a smaller range of changes,and significantly lower pain scores at different postoperative time points compared to the conventional anesthesia group(P<0.05).Conclusion In elderly patients undergoing hip replacement surgery,using ultrasound-guided bupivacaine for subarachnoid block can achieve ideal anesthesia and analgesic effects compared to traditional general anesthesia,shorten drug onset time,alleviate pain in elderly patients,maintain hemodynamic stability,and have significant clinical application effects.
