ObjectiveTo investigate the therapeutic effects of direct-acting antiviral agents (DAAs) combined regimens for hepatitis C virus (HCV) patients in Dehong Prefecture, Yunnan Province from 2022 to 2024, to analyze the characteristics of treatment failure patients, so as to provide a basis for discovering more effective treatment regimens in the future. MethodsData on HCV prevention and treatment in Dehong Prefecture was extracted from the China Disease Control and Prevention Information System. A total of 617 patients with HCV antiviral therapy were included, and the differences in variable characteristics among patients with different genotypes were analyzed using comparative statistical tests, including basic socio-demographic characteristics, biochemical testing indicators, and information on previous treatment and current treatment. In addition, the cure rate of HCV patients with diverse characteristics was compared, and the potential causes of treatment failure were explored simultaneously. ResultsThe cure rate of HCV was 96.8%, and statistically significant differences were observed in aspartate transaminase (AST) and alanine transaminase (ALT) levels, previous antiviral therapy history and initial treatment regimens among patients with different HCV genotypes (all P<0.05). Among the multi-type combination regimens, the cure rate of sofosbuvir (SOF)-containing regimens was 97.00%, that of velpatasvir (VEL)-containing regimens was 95.45%, and the cure rate of other treatment regimens, including the regimens with ribavirin (RIB) intervention, was 93.10%. Among the patients with treatment failure, 45.00% had genotype 3, 40.00% had abnormal abdominal ultrasound results, and all presented with elevated baseline AST test levels. ConclusionThe clinical treatment of HCV patients should consider the differences in genotype and biochemical test results. DAAs combined regimens for HCV have achieved a high cure rate in Dehong Prefecture and are applicable to HCV patients with diverse clinical characteristics, providing research evidence for wider application.

Objective To analyze the relationship between angiotensin type Ⅱ 1 receptor autoantibodies (AT1-AA),blood uric acid and urea nitrogen with hypertensive disorder complicating pregnancy (HDCP). Methods A total of 125 patients with HDCP diagnosed in the obstetrics department of Tianjin Municipal Bao-di District People's Hospital from August 2021 to February 2023 were randomly selected as the HDCP group, and 55 healthy pregnant women admitted to this hospital during the same period were selected as the control group.The HDCP group was divided into the gestational hypertension subgroup (n=77) and preeclampsia group (n=48) according to the degree of disease progression.The levels of serum uric acid,blood urea nitro-gen and AT1-AA were detected and compared between the HDCP group and control group and between the gestational hypertension subgroup and preeclampsia subgroup.Results There were no statistically significant differences in the age,gestational time,D-dimer,serum calcium and serum creatinine between the control group and the HDCP group (P>0.05).The levels of peripheral blood AT1-AA,serum uric acid and blood u-rea nitrogen in the HDCP group were higher than those in the control group,and the differences were statisti-cally significant (P<0.05).The levels of peripheral blood AT1-AA,serum uric acid and blood urea nitrogen in the preeclampsia subgroup were significantly higher than those in the gestational hypertension subgroup, and the differences were statistically significant (P<0.05).The Spearman rank correlation coefficient analysis showed that the levels of peripheral blood AT1-AA (r=0.301),serum uric acid (r=0.380) and blood urea nitrogen (r=0.257) levels were positively correlated with the severity degree of HDCP (P<0.01).The area under the curve (AUC) of AT1-AA,serum uric acid and blood urea nitrogen detection alone and combined de-tection in the diagnosis of HDCP were 0.680,0.714,0.647 and 0.725,and the corresponding Youden coeffi-cients were 0.368,0.380,0.306 and 0.439,indicating that the value of combined testing was higher than that of single item detection in the diagnosis of HDCP.Conclusion AT1-AA,serum uric acid and blood urea nitro-gen are correlated with the occurrence and development of HDCP,and the 3-item combined detection has high-er value.

Objective To evaluate the effect of acupuncture combined nerve block for surgery using meta-analysis.Methods We searched the data of randomized controlled trial (RCT) in Pubmed,Cochrane library,Embase,CNKI,VIP and Wanfang from the construction of database to May 2017.All RCTs that met the standards of acupuncture combined nerve block for patients undergoing surgery were collected.The meta-analysis was performed by Review Manager 5.3.Results Five trials containing 382 patients were included in this meta-analysis.Compared with nerve block alone,the pooled data showed that acupuncture combined nerve block reduced the fluctuation of intraoperative blood pressure (MD=-13.62,95％CI-15.41--11.84,P＜0.001) and heart rate (MD=-6.49,95％CI-8.61--2.36,P＜0.001),and VAS scores 8 h (MD=-1.07,95％CI -1.38--0.75,P＜0.001),12 h (MD=-1.11,95％CI-1.30--0.93,P＜0.001) and 24 h (MD=-0.15,95％ CI-0.25--0.04,P =0.006) after operation in the experimental group.Conclusion Acupuncture combined nerve block possibly improves the hemodynamic parameters and postoperative pain of patients undergoing surgery.

OBJECTIVETo evaluate the fatality rate of pneumoconiosis as well as the contributory factors in China in order to provide a foundation for prolonging the patients' lives.

METHODSChina National Knowledge Infrastructure (CNKI) and Wanfang Databases were searched to collect observational studies published between Jan, 2000 and Oct, 2013 on pneumoconiosis case fatality rate. Articles meeting the inclusion criteria were reviewed systematically, and analyzed by using Stata/SE 12.0, according to stage and type of pneumoconiosis and whether complicated with tuberculosis.

RESULTS41 papers were included for meta-analysis. The pooled total case fatality rate of pneumoconiosis was 31.2%. The pooled case fatality rate of pneumoconiosis patients of stage 1, 2 and 3 were 25.4%, 39.8%and 57.5%, respectively. The pooled case fatality rate of patients with silicosis, coal worker's pneumoconiosis, foundry worker's pneumoconiosis, asbestosis and cement pneumoconiosis were 35.8%, 32.4%, 24.7%, 35.1%and 5.5%, respectively. The complication with tuberculosis was a risk factor for the death of pneumoconiosis patients and the pooled RR was 1.82 (95%CI: 1.59∼2.08).

CONCLUSIONThere are significant differences in the case fatality rate of pneumoconiosis among different stages and different types of pneumoconiosis and whether complicated with tuberculosis.

Objective To analyze the polymorphisms of glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) gene Exon1 and Exon25,GPI-PLD activity of leucocyte in peripheral blood and their relationship in systemic lupus erythematosus patients of Han nationality in Hunan Chinese.Methods The polymorphisms were analyzed by PCR-SSCP and sequencing. GPI-PLD levels were determined by using glycosylphosphatidylinositol (GPI) anchored placental alkaline phosphatase (PLAP) as substrate and triton-X114 partioning.Results There were fourteen variations in the coverage of GPI-PLD gene Exon 1 of both 109 healthy persons' and 62 systemic lupus erythematosus patients',including seven variations at transcriptional start site upstream and seven variations at Exon1. The codons of variation were 14TTG→AAG (Leu14Lys),17CTC→GTC (Leu17Val),20AGA→AAA (Arg20Lys),21GGT→GGG (Gly21Gly),30GTA→ATA (Val30Ile),which leaded to four missense mutations and one synonymous mutation. In addition, the frequency of the variation at transcriptional start site upstream -24 C→T was significantly different between healthy control and systemic lupus erythematosus patients. At meanwhile, there was a variation in Exon25, the +60496 G→A, between two groups. The total various frequency, which was determined by SSCP, of healthy person was 33 03 percent and systemic lupus erythematosus patient was 25 81 percent. On the basis of the percentage of GPI-anchored PLAP conversion, the leucocyte GPI-PLD activities of total 62 systemic lupus erythematosus patients were measured. As compared with 109 healthy persons as control group, the leukocyte GPI-PLD activities of systemic lupus erythematosus patients were significantly raised, but GPI-PLD activities were not correlated with polymorphism sites significantly.Conclusions The leukocyte GPI-PLD gene in peripheral blood, which belongs to healthy persons and systemic lupus erythematosus patients of Han mationality in Hunan Chinses,is polymorphism.The frequency of transcriptional start site upstream -24 is significantly different between healthy control and systemic lupus erythematosus patients.The leukocyte GPI-PLD activeties of patients' also significantly increase.
