Objective To investigate the expression of Beclin1,p62 and Atg5 in serous ovarian cancer and its clinical significance.Methods The expression of Beclin1,p62 and Atg5 was detected in 50 serous ovarian cancer tissues by immunohistochemical method,and the relationship between their expression levels and the clinical parameters of serous ovarian cancer patients were analyzed.Results The expression of Beclin1 and Atg5 in serous ovarian cancer tissue was significantly lower than that in normal ovarian tissue,but p62 was significantly higher than that in normal ovarian tissue,and the difference had statistically significance (P<0.05).The expression of Beclin1 and Atg5 were correlated with degree of cell differentiation and clinical stage (P<0.05),while the expression of p62 was associated with clinical stages and lymph node metastasis (P<0.05).Conclusions The abnormal expression of Beclin1,p62,Atg5 in serous ovarian cancer,which can lead to reduced autophagy body formation and autophagy activity,may be involved in the occurrence and development of serous ovarian cancer.

Objective To evaluate the surgical corrective results of prominent mandibular angle with masseter muscle hypertrophy by using intraoral approach. Methods One hundred and twenty three cases with various degrees of prominent mandibular angle with masseter muscle hypertrophy were treated through intraoral approach. The basic surgical procedures included masseter muscle reduction (type Ⅰ), mandibular angle osteotomy (type Ⅱ) and angle-splitting osteotomy (type Ⅲ). The type Ⅰ was completed in 4 cases, type Ⅱin 16 cases, type Ⅲ + type Ⅰ in 56 cases, type Ⅲ in 19 cases, type Ⅲ + type Ⅰ in 9 cases, type Ⅲ + type II in 12 cases, type Ⅲ + type Ⅱ+ type Ⅰ in 7 cases. Genioplasty was simultaneously performed in 69 cases.Results The overwidth of the lower face was effectively corrected. The cosmetic results, as determined by both patients and surgeons, were good. No complications, such as facial never injury, or inferior alveolar never injury, occurred in any patients. Conclusions In order to reach good cosmetic results at the patients' lateral view and frontal view, considerations should be determined according to the degrees of the deformities and patient's desires, to choose suitable surgical procedures.

ObjectiveTo investigate the situation of mother to child transmission of HIV after mothers acquired HIV prenatally or before pregnancy and the related factors. Methods Two hundred and seventy-seven mothers who acquired HIV prenatally or before pregnancy and their 322children from Yi-ning city of Xinjiang Uygur autonomous region and some counties of central China were enrolled in this study from January 2000 to December 2009.Subtypes of HIV were determined by detection of Gag sequence,the rate of HIV transmission from mother to child was calculated and its related factors were analyzed by Chi-square test and Logistic regression analysis.ResultsThe HIV subtype of all mothers who were infected through blood (n=174) was B'.The major subtype of mothers who were infected via sexuality (n =58) was recombined subtype CRF01-BC (n=35) and CRF-AE (n=20),accounting for 60.3% and 34.5%,respectively,and only 3 mothers with B'subtype (5.2%).Twelve infants died before HIV detection,and 108 infants out of the rest 310infants were found to be HIV positive, giving the HIV mother-to-child transmission rate of 34.8% (95% CI:29.5%-40.1%).The infection rate of bottle feeding infants was lower than that of breastfeeding infants [12.5% (6/48) vs 38.9% (102/262),x2 =12.484,P=0.000].The infection rate of the infants whose mothers' HIV infection <7 years was lower than that of the infants whose mothers' HIV infection ≥7 years [28.8% (46/160) vs 54.2% (32/59),x2 =12.211,P=0.000].Multi-factor Logistic analysis showed that the duration of maternal HIV infection (OR =1.342,95% CI:1.189-1.515,P=0.000) and duration of breastfeeding (OR =1.137,95% CI:1.053-1.227,P=0.001) were risk factors of HIV vertical transmission.ConclusionsThe HIV subtypes might be associated with transmission route.Formula feeding could decrease the vertical transmission rate of HIV,while long duration of maternal HIV infection and breastfeeding might increase the vertical transmission rate of HIV.

Objective To investigate the effect of combined antiretroviral therapy (cART) on anal human papillomavirus (HPV) infection in human immunodeficiency virus (HIV)-infected men who sex with men (MSM).Methods HIV-infected MSM naive of cART who visited Wuhan Dermatological Hospital from June 2012 to December 2013 were enrolled in a longitudinal study before starting cART,including 81 HIV-positive and 50 HIV-negative cases.HPV infection situations between HIV-positive and HIV-negative MSM were compared.And anal HPV infection rate and condyloma acuminate incidence of HIV-positive MSM before and after cART were also compared.HPV genotyping was performed by universal primer PCR and reverse dot hybridization.The statistical analysis was done by t test or x2 test.Results The prevalence rates of HPV infection,high-risk HPV infection and multiple HPV subtypes infection in HIV-positive MSM were all significantly higher than those in HIV-negative MSM (91.4 % vs 62.0 %,75.3 % vs 30.0 %,56.8 % vs 20.0 %,respectively,x2 =16.75,26.05,and 19.10,respectively,all P<0.05).The prevalence rates of anal HPV infection,high-risk HPV infection and multiple HPV subtypes infection in 77 HIV-positive MSM at month 36 of cART were all significantly decreased than baseline (90.9% vs 74.0%,75.3% vs 44.2% and 57.1% vs 41.5%,respectively,x2 =7.590,15.551,and 3.741,respectively,all P<0.05).HPV16 and HPV43 infection rates were reduced from 27.3% at baseline to 15.6% and 13.0%,respectively at month 36 of cART (x2 =16.92 and 14.86,respectively,both P<0.05).Condyloma acuminate incidence also reduced from 16.9% at baseline to 5.2% at month 36 (x2 =4.069,P<0.05).Conclusions The prevalence of anal HPV infection in HIV-positive MSM is higher than HIV-negative MSM.cART could reduce the prevalence of anal HPV infection rate and condyloma acuminate incidence,especially high-risk HPV infection.

Objective To study the expression and significance of Nrf2 and caspase-3 in non-small cell lung cancer (NSCLC).Methods The specimens from 82 cases of NSCLC in our hospital from September 2015 to December 2017 were selected for observation.All patients were surgically resected to obtain NSCLC specimens.The expression of Nrf2 and caspase-3 in NSCLC was detected by immunohistochemistry and its clinical significance was analyzed.Results The positive expression rate of Nrf2 in NSCLC (63.4%) was significantly higher than that in normal tissue (30.0%),with statistically significant difference (P < 0.05).The analysis of clinical characteristics showed that the expression of Nrf2 in NSCLC was related to tumor diameter,tumor node metastasis (TNM) stage,lymph node metastasis and distant metastasis (P < 0.05).The expression of Nrf2 in NSCLC was not significantly associated with gender,age,smoking history,case classification,and histological differentiation (P > 0.05).The positive rate of caspase-3 in NSCLC (40.2%) and the positive rate of caspase-3 in normal tissues (40.0%) were not statistically different (P > 0.05).Analysis of clinical characteristics showed that the expression of caspase-3 in NSCLC was related to TNM stage,lymph node metastasis,distant metastasis,and the difference was statistically significant (P < 0.05);the expression of Nrf2 in NSCLC was not significantly associated with gender,age,smoking history,case classification,tissue differentiation,and tumor diameter (P > 0.05).Conclusions The abnormal expression of Nrf2 and caspase-3 is correlated with the progression of NSCLC and the malignant biological behavior.Active detection of Nrf2 and caspase-3 levels can clinically determine the clinical stage,lymph node metastasis and distant metastasis of NSCLC,providing information to facilitate clinical development of relevant interventions.

The changes of metabolic profile are closely related to external stimulus, and the concentration of the metabolite can directly reflect the physiological or pathological states of organisms. Therefore, the quantitative detection of metabolites is necessary. However, traditional targeted metabolomic methods have such drawbacks as narrow coverage and low sensitivity. In recent years, derivatization techniques have developed rapidly in the field of metabolomics. Derivatization reagents for amine, hydroxyl, carboxyl, carbonyl, hydrosulphonyl and other groups have been used in metabolomics research. This paper introduces various derivatization reactions and their applications according to group classification and reviewes the characteristics of multi-group derivatization techniques, with a propect of their research directions and challenges.
