Objective To explore the clinical diagnosis and treatment of cesarean scar pregnancy (CSP).Methods The clinical data of 83 CSP patients who first visited to our hospital during the period from January 2014 to December 2016 were collected for a retrospective analysis.Among the 83 cases, 79 were diagnosed by ultrasound, 2 were diagnosed by MRI, and 2 were misdiagnosed (2.4%).Curettage under ultrasound monitoring was used in 11 cases, including 10 cases of type Ⅰ and 1 case of type Ⅱ according to the 2016 classification standard of Chinese Medical Association.Curettage under ultrasound monitoring after methotrexate(MTX) was used in 34 cases, including 30 cases of type Ⅰ and 4 cases of type Ⅱ.Curettage under ultrasound monitoring after uterine artery embolization (UAE) was used in 37 cases, including 3 cases of type Ⅰ, 30 cases of type Ⅱ, and 4 cases of type Ⅲ.Besides, 1 case of type Ⅲ was treated with curettage under laparoscopic monitoring after UAE.Results All the operations were successful, without hysterectomy or conversion to open surgery.No persistent pregnancy was occurred.A total of 65 cases were followed up and 18 cases were lost.The β-hCG was decreased to normal after 2-5 weeks.After 4-9 weeks, menstruation was recovered.Conclusion According to different clinical types of CSP and gestational weeks, curettage under ultrasound or laparoscopic monitoring after different pretreatement is simple, safe and effective in primary hospitals.

Objective To study the relationship between urinary biopyrrin level and the degree of coronary atherosclerosis.Methods 220 inpatients with coronary artery disease,which were identified by coronary angiography within 1 year(from April 2006 to April 2007),and 80 healthy examinees (healthy group)were enrolled in the study.The 220 inpatients were divided into three groups according to the involved number and extent of coronary arteries:1 vessel group(group A,n=80),2 vessel group(group B,n=75)and 3 vessel group(group C,n=65).Enzyme linked immunosorbent assay (ELISA)was applied to detecting urinary biopyrrin level for all subjects.Results Compared with that of healthy control group,the urinary biopyrrin in group A,B and C was much higher(P＜0.05).There were statistical difference of urinary hiopyrrin level among the different groups r(P＜0.05).Conclusion Biopyrrin is significantly associated with the involved number and extent of coronary arteries.

Objective:To establish an improved method for the determination of diethylene glycol and ethylene glycol in glycerol on the basis of the method in Chinese pharmacopoeia (2010 edition). Methods: Glycerol samples were extracted by methanol, and detected by gas chromatography with a flame ionization detector. The column was a DM-624 capillary column(30 m × 0. 53 mm,3μm), and the initial temperature was 80℃ in the first 6min and then risen to 100℃ at the speed of 50℃·min-1, kept for 8min,fi-nally risen to 220℃ at the speed of 10℃·min-1 , kept for 10min. The split injection was used with the split ratio of 100∶1. The in-jection temperature was 250℃ and the detector temperature was 280℃. The flow rate was 6. 0ml·min-1 . Results:The RSD(%) of the method was lower than 5%, and the resolution of all chromatographic peaks met the requirements of the pharmacopoeia. The meth-od was used to analyze the commercial product of glycerol, and the contents of diethylene glycol and ethylene glycol were both less than the specified limits. Conclusion:The method is simple and rapid, and suitable for glycerol impurity inspection.

Inflammasome is a multi-protein complex which plays an important role in innate immune defense,and can adjust the activation of caspase-1 and promote the production of cytokines. NLRP3 is an important member of inflammasome Nod-like receptor(NLR)family,and its activation and expression occur mainly in macrophages and dendritic cells. NLRP3 can sense the pathogen associated molecular patterns(PAMPs)and damage associated molecular patterns(DAMPs)and initiate the inherent immune response,which plays an important role in the pathogenesis of autoimmune diseases. This article reviewed the advances in study on NLRP3 in autoimmune diseases.

Objective To investigate the association of human papilloma virus (HPV) typing and p53 expression with radiosensitivity in patients with cervical cancer.Methods A total of 80 patients with cervical cancer from 2014 to 2016 were enrolled,and among these patients,40 had stage Ⅰ B+ Ⅱ A disease and 40 had stage Ⅱ B +ⅢA disease.HPV genotype was identified and p53 expression was measured.All the patients underwent external and internal pelvic irradiation alone,and the correlation between short-term therapeutic effect and HPV typing/p53 expression was analyzed.The chi-square test or the Fisher's exact test was used for statistical analysis,and Spearman rank correlation analysis was also performed.Results The radiotherapy-insensitive (stable disease+progressive disease) group had higher p53 positive rates than the radiotherapy-sensitive (complete response+partial response) group (stage Ⅰ B+ Ⅱ:100％ vs.80.0％,P=0.044;stage Ⅱ B+ⅢA:100％ vs.90.0％,P=0.013).The expression of p53 was negatively correlated with radiosensitivity (r =-0.427,P =0.000).In the radiotherapy-insensitive group of patients with stage I B + Ⅱ and Ⅱ B +Ⅲ A,the rate of HPV multiple infections was higher than that of single subtype infection (65.0％/95.0％ vs.35.0％/5.0％,P=0.004 and 0.003),while in the radiotherapy-sensitive group,the rate of single subtype infection was higher than that of multiple infections (85.0％/60.0％ vs.15.0％/40.0％,P=0.004 and 0.003).The highest detection rate of HPV16 was 66.3％ in all patients,and the highest detection rate of HPV18 was 60.0％ in the radiotherapy-insensitive group.Conclusions High expression of p53 is associated with radioresistance in patients with cervical cancer.Patients with HPV muhiple infections have poor radiosensitivity,and HPV16 is the most common subtype in dual infection.Among patients who do not achieve remission after radiotherapy,HPV multiple infections with HPV18 as the main pathogen has the highest detection rate.

Objective To investigate the protective effect of IL-37 on hepatocyte injury against hypoxia/reoxygenation (H/R) by promoting polarization of M2-type macrophages and its molecular mechanisms.Methods Real-time fluorescent quantitative PCR (qRT-PCR) and Western blot were used to detect the levels of IL-37 mRNA and protein in human monocyte-macrophage THP-1 cells with different polarizations.The lentivirus with IL-37 gene was infected into THP-1 cells.The levels of CD206,CD86,ARG1 and iNOS mRNA was detected by qRT-PCR.The levels of CD163 and CD86 protein was detected by flow cytometric analysis.THP-1 cells and L02 cells were co-cultured by Transwell and treated with H/R.The survival rate and apoptotic rate of L02 cells were detected.The levels of alanine transaminase (ALT) and aspartate aminotransferase (AST) in culture medium were measured.The levels of STAT6 and its phosphorylation in THP-1 cells were detected by Western blot.Results The levels of IL-37 mRNA and protein were up-regulated in M2-type macrophages.IL-37 promoted the polarization of M2-type macropahges.M2-type macrophages induced by IL-37 were cocultured with L02 cells,the survival rate was significantly increased by H/R treatment (P =0.015),while the apoptotic rate,ALT level and AST level were significantly decreased (P＜0.001).The level of phosphorylated STAT6 in THP-1 cells overexpressing IL-37 was up-regulated (P ＜ 0.01).Conclusions IL-37 can induce polarization of M2-type macrophages and protect hepatocyte injury against H/R.Its mechanism may be related to STAT6 signal pathways.

OBJECTIVE:To investigate the effects and safety of Sophoraflavescens preparation combined with Fuzheng huayu capsule on hepatic hemodynamics and fibrosis indexes in patients with hepatitis B liver cirrhosis.METHODS:One hundred and two patients diagnosed as hepatitis B liver cirrhosis in our hospital during Feb.2013-Jun.2014 were divided into combination group and control group according to random number table,with 51 cases in each group.Control group was treated with Adefovir dipivoxil capsules 10 mg,po,qd;combination group was additionally given Fuzheng huayu capsules 1.5 g,po,tid+Sophora flavescens preparation (Matrine glucose injection 250 mL,ivgtt,qd,in the first 3 months,oxymatrine capsules 200 mg,po,tid,after 3 months) on the basis of control group.Both groups were treated for 12 months.The levels of HBV-DNA,liver function indexes (AST,ALT,TBIL),portal hemodynamic indexes [main portal vein inner diameter (D),mean blood flow velocity (Ⅴ)] and liver fibrosis indexes [laminin protein (LN),hyaluronic acid (HA),type Ⅳ collagen (Ⅳ-C)] were observed in 2 groups before and after treatment.The negative conversion rate of HBV-DNA and incidence of ADR were recorded.RESULTS:Three cases lost to follow up,and a total of 48 effective cases were included in control group;5 cases lost to follow up,and a total of 46 effective cases were included in combination group.Before treatment,there was no statistical significance in HBV-DNA levels,liver function indexes (AST,ALT,TBIL),liver fibrosis indexes (LN,HA,Ⅳ-C) and portal vein hemodynamic indexes (D,V) between 2 groups (P＞0.05).After treatment,above indexes of 2 groups were decreased significantly,and the combination group was significantly lower than the control group,with statistical significance (P＜0.05).The negative conversion rate of HBV-DNA in combination group was 93.5％,which was significantly higher than 79.2％ of control group,with statistical significance (P＜0.05).There was no statistical significance in the incidence of ADR between 2 groups (P＞0.05).CONCLUSIONS:Sophora flavescens preparation combined with Fuzheng huayu capsules can promote the recovery of liver function,regulate liver hemodynamics and alleviate hepatic fibrosis in patients with hepatitis B liver cirrhosis with good safety.
