Objective:To investigate the factors that influence the prolongation of gestation following emergency cervical cerclage.Methods:This retrospective study included 88 singleton pregnant women who were diagnosed with cervical incompetence and underwent emergency cervical cerclage at 12-26 weeks of gestation in the Jiaxing Maternity and Child Health Care Hospital from January 1, 2019 to September 1, 2022. The participants who delivered after 28 gestational weeks were assigned to the success group ( n=77), while those who delivered or miscarried before 28 gestational weeks were assigned to the failure group ( n=11). Two independent sample t-test or Mann-Whitney U test was used for comparison between groups. The factors affecting the prolongation of gestation after the procedure were selected by univariate analysis and multiple regression equations. Results:The success rate (delivery rate≥28 weeks) was 87.5% (77/88). There were six women delivered at 28-31 +6 weeks of gestation (6/77, 7.8%), two at 32-33 +6 weeks of gestation (2/77, 2.6%), 16 at 34-36 +6 weeks of gestation (16/77, 20.8%), and 53 at 37 weeks of gestation or later (53/77, 68.8%). Multiple regression analysis indicated that three times of early pregnancy miscarriage ( β=－5.1, 95% CI: -9.5 to -0.7), five times of early pregnancy miscarriage ( β=－11.8, 95% CI: -22.1 to -1.6), had two live births ( β=－6.9, 95% CI: -12.9 to -0.9), gestational age at cerclage ( β=－0.6, 95% CI: -1.0 to -0.3), external cervical os dilation<15 mm ( β=－12.1, 95% CI: -22.5 to -1.8) and ≥15 mm before cerclage ( β=－11.0, 95% CI: -21.4 to -0.71) were factors affecting the prolongation of gestation after cerclage. After adjusting for maternal age and weight before emergency cervical cerclage, five times of early pregnancy miscarriage ( β=－18.1, 95% CI: -28.3 to -7.8), gestational age at cerclage ( β=－0.6, 95% CI: -1.0 to -0.3), and external cervical os dilation≥15 mm before cerclage ( β=－11.4, 95% CI:－21.2 to -1.6) remained the significant influencing factors (all P<0.05). Conclusion:The number of early pregnancy miscarriages, gestational age at cerclage, and the width of external cervical os dilation before cerclage≥15 mm are the factors that influence the prolongation of gestation after the emergency cervical cerclage procedure.

Objective To study the risk factors of acute kidney injury(AKI)secondary to the decompensated stage of chronic hepatitis B(CHB)cirrhosis.Methods A total of 316 patients with decompensated CHB cirrhosis diagnosed and treated in the Affiliated Hospital of Shaoxing University of Arts and Sciences from January 2018 to January 2024 were divided into CHB cirrhosis decompensated group(CHBCD group,n=72)and CHB cirrhosis decompensated secondary AKI group(CHBCD+AKI group,n=244).Compare the differences in clinical data between two groups of patients.Spearman rank correlation analysis detects the correlation between indicators and serum creatinine(Scr)and blood urea nitrogen(BUN).Multivariate Cox regression analysis of risk factors for AKI secondary to CHB cirrhosis.Effectiveness of receiver operating characteristic curve were analyzed in predicting AKI secondary to CHB cirrhosis.Kaplan-Meier survival model and Log rank were used to compare the difference in survival time between two groups of patients.Results The hepatic encephalopathy rate,prothrombin time(PT),total bilirubin(TBIL),Scr,BUN,cystatin C(Cys-C),Child-Pugh grade C proportion,and model of end-stage liver disease(MELD)score in CHBCD+AKI group were significantly higher than those in CHBCD group(P＜0.05),and Alb was significantly lower in patients in CHBCD group(P＜0.05).In CHBCD+AKI group,hepatic encephalopathy,PT,TBIL,Cys-C,Child-Pugh classification,and MELD score were positively correlated with Scr and BUN(rs＞0,P＜0.05),and negatively correlated with Alb(rs＜0,P＜0.05).Scr ≥467.2pmol/L,BUN ≥ 11.5mmol/L,Cys-C≥2.7mg/L,Child-Pugh grade C,and MELD score≥ 15.4 points were independent signs of AKI secondary to the decompensated stage of CHB cirrhosis.BUN,Cys-C,and MELD scores were more effective than Scr and Child-Pugh grades in predicting AKI secondary to the decompensated stage of CHB cirrhosis.The median survival time of patients in CHBCD+AKI group was significantly lower than that of CHBCD group.Conclusion Scr,BUN,Cys-C,Child-Pugh grade,and MELD score are independent risk factors for AKI secondary to the decompensated stage of CHB cirrhosis,and the survival rate of AKI secondary to the decompensated stage of CHB cirrhosis reduced.

Objective To investigate the epidemiological information of patients in pre-hospital medical care for our large and medium-sized cities and probe the patients' characteristic. Method The data in 2008 were exported from the computer databases of 8 large and medium-sized cities' emergency medical centers in our country.The thorough records of data were conducted to statistical analysis. Results ( 1 ) The scheduling time, running time, rescue time, returning time, total time and service radius in the pre-hospital medical care group were 2.16± 1.10(min), 14.01 ±6.82(min), 12.12±5.96(min), 14.08± 6.85(min), 42.34± 20.21(min)and 8.50±4.18(km), and the above parameter in the non-death group were 2.19 ± 1.13(min), 14.15 ± 7.14(min),11.60±6.72(min), 14.92 ±6.89(min), 41.86± 19.53(minutes) and 8.63±4.31(Km), and the above parameter in the death group were 2.10± 1.08(min), 13.68 ± 7.14(min), 25.25 ± 12.34(min), 13.75±6.48(min), 54.74 ± 25.47(min) and 7.86± 3.91(Km), and the above parameter in the non-sudden cardiac death group were2.09± 1.03(min), 13.58±6.78(min), 25.53± 12.34(min), 13.60± 6.54(min), 53.79±23.77(min) and 7.67 ± 3.86(Km), and the above parameter in the sudden cardiac death group were 2.12 ±1.02(min), 14.10±7.05(min), 24.79± 12.08(min), 13.79±6.61(min), 54. 80 ± 25. 36( min) and 7.90±3.92(Km) respectively. The scheduling time, running time, returning time and service radius in the death group were less than those of the non-death group, but the rescue time and total time of the former were more than those of the latter respectively ( P ＜ 0.05 or P ＜ 0. 001 ). The scheduling time and returning time didn' t have significant difference between the sudden cardiac death group and the non-sudden cardiac death group respectively ( P ＞ 0.05), but the running time, total time and service radius of the sudden cardiac death group were more than those of the non-sudden cardiac death group, and the rescue time of the former was less than that of the latter respectively ( P ＜ 0.05 or P ＜ 0.001 ). (2)The patients' amount in pre-hospital medical care group, the non-death group, the death group, the non-sudden cardiac death group and the sudden cardiac death group were at most in first quarter, and the least time slice of patients' amount were 4:00～ 6:00, 4:00～6:00, 4:00～ 6:00, 22:00～ 24:00, 2:00～4:00 respectively, and the most time slice of patients' amount were 20:00～ 22:00, 20:00～22:00, 8:00～ 10:00, 2:00 ～ 4:00, 8:00 ～ 10:00 respectively. (3)In 241 876 cases of pre-hospital medical care group, the patients' amount of trauma was at most, whose age grades was by far among21 ～50, and the others in sequence were nervous system, circulatory system, other group, digestive system, respiratory system and poisoning group respectively, whose age grades in nervous system, circulatory system and respiratory system was by far above 51, especially above 70. The patients' age grades in other group and digestive system had two climax age groups, which the one was 21 ～ 30, and the other was above 70. The patients' age grades in poisoning group was by far among 21 ～ 50, which the patients' amount of acute alcoholism was at the most. (4) In 12 568 cases of death group, the death amount of circulatory system, other group, respiratory system, nervous system and digestive system ranked at the lst,2nd,4th,5th 8th respectively, whose age grades was by far above 51, especially above 70,and the patients' amount of sudden cardiac death was at the most in the death amount of circulatory system. The death amount of trauma and poisoning group ranked at the 3rd, 6th respectively, whose age grades was by far among 21 ～ 50. (5)The total amount, the death amount and the sudden cardiac death amount of male patients were more than those of female patients. (6)The percentage of the death group to the pre-hospital medical care group was 5.20%, and the percentage of the sudden cardiac death group to the pre-hospital medical care group was 1.29%,and the percentage of the sudden cardiac death group to the death group was 24.87 %, and the percentage of the sudden cardiac death group to the circulatory system group was 67.33 %. Conclusions ( 1 )The trauma and the sudden cardiac death are the overriding reason of disease and the overriding reason of death in our large and medium-sized cities respectively. (2) It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular and cerebrovascular diseases, discerning the critical illness early and improving the level of pre-hospital medical care. (3)It is a strong method to decrease the total amount and the death amount of the trauma, especially in traffic accident, by strengthening safety in production, observing traffic regulation and enhancing the legal awareness.

Hepatic stellate cells(HSCs) are the mesenchymal cells in the liver. In the process of tumori-genesis and metastasis, the interactions between HSCs and tumor ceils play an important role in promoting tumor invasion through extracellular matrix remodelling. Here we review the latest investigative advances a-bout the tumor-stromal interactions.

OBJECTIVE To investigate macrolide resistance and main molecular mechanisms in Mycoplasma pneumoniae. METHODS Thirty two throat swabs from children infected with M. pneumoniae were cultured by modified Hayflick medium. Antibiotic susceptibility test was used to screen the macrolide-resistant M. pneumoniae. The 23S rRNA gene sequences of the strains were determined with polymerase chain reaction and sequencing. RESULTS Nineteen strains were isolated from 32 throat swabs successfully.Fifteen strains were resistant to macrolide antibiotics according to the results of antibiotic susceptibility test. Once the strain was resistant to one of macrolide antibiotics,it would be resistant to the others. Sequencing results of the sensitive strains and the standard strain FH were completely same. Fifteen resistant strains presented A2063G point mutation in 23 SrRNA region Ⅴ, in which 2 examples showed the coexistence of the sensitive strain and the resistant strain. CONCLUSIONS Macrolide-resistant M. pneumoniae is common and serious at present. The antibiotic resistant isolate carries point mutations of the 23S rRNA region Ⅴ.
