Of the 10 cases underwent vaginal and G-spot injection, 6 cases were satisfied after the operation. The morphology was very satisfactory, 2 cases were more satisfactory, and 2 cases were less satisfactory. According to a survey of 25 cases of postoperative sexual life satisfaction, 19 cases (76%) had a significant improvement in their conscious sexual life, 3 cases had a more obvious improvement, 1 case had less improvement, and 2 cases had no conscious improvement.Conclusions:The autologous fat injection based on the fine anatomy and aesthetics of the perineum can significantly improve the aesthetic appearance of the perineum.
ABSTRACT
Objective:To investigate the clinical features, risk factors and prognosis of Clostridium difficile infection/colonization (CDI/CDC) in emergency intensive care unit (EICU) of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine, then provides theoretical basis for clinical treatment. Methods:A retrospective case-control study was conducted. The data of EICU patients admitted to Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from June 2016 to June 2020 were collected. Taking the CDI/CDC patients as research objects [ Clostridium difficile (CD) positive group] and the CD negative patients with the same gender and age difference less than 5 years who were admitted to the hospital during the same period as the control (CD negative group). Demographic information, risk factors, prognosis and stool samples were collected. Single factor analysis and binary Logistic regression were used to analyze the CD positive infection rate, risk factors, and hospital death of patients with different clinical characteristics. Results:About 487 patients in EICU were included, 76 cases were taken into CD positive group, CD positive rate was 15.6%, including CDI 11 cases, CDC 65 cases. Among the CD positive group, all of the cases used proton pump inhibitor (PPI), and 75 cases used at least one antibiotic. Seventy-six CD negative patients with or without diarrhea (CD negative group) were included in this study. Among them, 75 patients used PPI and 74 patients used at least one antibiotic. Univariate analysis showed that acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), duration of hospitalization, and carbapenem use were the risk factors for CDI/CDC. There were significant differences in the above indicators between CD positive group and CD negative group [APACHEⅡ: 18.0 (12.2, 25.8) vs. 10.0 (7.0, 14.0), duration of hospitalization (days): 46.0 (30.5, 72.5) vs. 18.5 (9.2, 37.0), proportion of carbapenems: 81.6% (62/76) vs. 64.5% (49/76), all P < 0.05]. Binary Logistic analysis regression analysis showed that APACHEⅡ score [odds ratio ( OR) = 0.802, 95% confidence interval (95% CI) was 0.730-0.882, P < 0.01] and duration of hospitalization ( OR = 0.960, 95% CI was 0.942-0.978, P < 0.01) were independent risk factors for CDI/CDC. There was no difference in overall mortality between the CD positive group and CD negative group [27.6% (21/76) vs. 38.2% (29/76), P = 0.167]. Conclusions:Critically ill patients in EICU routinely use PPI and antibiotics, and the use of antibiotics does not affect the CD positive rate. The independent risk factors of CDI/CDC are the APACHEⅡ score and the duration of hospitalization, but fecal CD positive has no obvious influence on death.

ABSTRACT
Objective To study the relationship between the genetic polymorphism of interleukine-6 (IL-6)-174 and the response to benazepril treatment in patients with hypertensive renal damage. Methods Two hundred and eighty-four patients with hypertension were enrolled in this study. The hypertensive renal damage was defined by the measurement of urinary albumin excretion rate (UAER). One hundred and sixty healthy subjects were enrolled simultaneously as control group. Blood samples were obtained from all the subjects, and plasma levels of IL-6 and the genotype of gene IL-6-174 were detected. The patients with hypertensive renal damage were treated with benazepril for 16 weeks. The responses were evaluated by the changes of UAER level to benazepril in different genotypes. Results Genotype CC was the most common of the gene IL-6-174 in patients with hypertension, followed by GG and GC successively, with the G/C allele frequency of 47%and 53%(P<0.05), while in patients with hypertensive renal damage, GG was the most common genotype of the gene IL-6-174, followed by GC and CC successively, with the G/C allele frequency of 68%and 32%(P<0.05). After benazepril treatment, the UAER was decreased most in patients with genotype CC, followed by GC and GG successively ( P<0.05). Conclusion The G allele frequency of the gene IL-6-174 is related with hypertensive renal damage in patients in Ningxia, with GG as the most common genotype. The patients with CC genotype have the best response to benazepril treatment, with most decreased UAER.
ABSTRACT
Background and purpose:Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. Intrahepatic recurrence is the main factor affecting its medium-term survival rate. Therefore, the search for the markers of metastasis is essential. This study aimed to evaluate the relationship of expression of tyrosine kinase phosphorylation Tyr416 of sarcoma (SRC pY416) in HCC with clinical parameters and prognosis. Methods:Immunohistochemical method and Western blot were used to detect the expression of non-receptor tyrosine kinase (SRC pY416) in 112 cases of HCC tissues and 40 cases of corresponding cancer adjacent normal liver tissues. Hepatitis B virus (HBV) DNA and alpha fetoprotein (AFP) in patients were detected with chemiluminescence. In the 12 months Follow-up of the study,the association between SRC pY416 expression and clinical parameters was analyzed. Results:SRC pY416 expressions in HCC (65.40±15.69) were higher than those in cancer adjacent normal liver tissues (11.25±2.73,P<0.001). The expressions of SRC pY416 were all associated with the age, the liver cirrhosis, the complete capsule, the tumor differentiation, the HBV DNA and the AFP value of the patients (P<0.01). 12 months after operation, single factor analysis showed that the recurrence was associated with the tumor differentiation, the HBV DNA, the AFP value and the expression of SRC pY416 of the patient (P<0.01). Multivariate analysis showed that the expression of SRC pY416 was an independent prognostic factor for recurrence and metastasis in patients with HCC in 12 months. Conclusion:SRC pY416 may play an important role in the metastasis of HCC. The expression of SRC pY416 may be the marker for HCC liver metastasis.

ABSTRACT
Two non-destructive instrumental methods, infrared spectroscopy (IR) and X-ray diffraction (XRD), were studied for quality evaluation of Lobelia chinensis Lour. (L. chinensis). We obtained the IR spectra and XRD patterns of L. chinensis collected from different sources. The similarity of samples was analyzed by cal-culating the cosine coefficient. The cosine values were in the range of 0.83–0.90, indicating that the main components of L. chinensis samples are similar. Sample L1 and L6 showed a slightly lower similarity than that of L2, L3, L4, L5 detected by the two methods, which revealed that IR and XRD methods exhibited analogous detection ability for quality evaluation of L. chinensis. The two methods could be highly re-commended as simple and rapid detection means for quality evaluation of L. chinensis.

Background and purpose:It has been reported that gap junctional (GJ) function was signiifcantly decreased in hepatocellular carcinoma (HCC) tissues and cell lines. However, the increased GJ suppress tumorigenesis and the development of liver cancer. This study therefore aimed to examine the effect of simvastatin on GJ function between Hep3b cells. Thus, the exploition of drugs to increase GJ function between liver cancer cells will provide an efifcient approach to ifght against liver tumor as well as increase cytotoxicity of antitumor agents.Methods:SRB was used to assay the toxicity of simvastatin. The effect of simvastatin on GJ function was determined by “Parachute” dye-coupling assay and scrape loading/dye transfer assay.Results:Pretreated Hep3b cells with simvastatin at the concentration of 1, 5 or 10 μmol/L for 24 h did not induce the cytotoxicity. So simvastatin at the concentration of 5 and 10 μmol/L would not reduce the amount of GJ on cell membranes. “Parachute” dye-coupling assay showed that the treatment with 5 and 10 μmol/L simvastatin for 4 h enhanced the dye spread through GJ in Hep3b cells. Similarly, scrape loading/dye transfer assay showed that simvastatin could induce the increasing spread of lucifer yellow (Ly, Sigma) around the scoifng cells with increasing concentrations.Conclusion:Simvastatin could increase the GJ function of Hep3b cells.
