Objective To evaluate and compare the curative effect between the microinvasive craniopuncture therapy and the clearance of hematoma by craniotomy with small bone flap in treating patients with moderate cerebral hemorrhage (30-60 ml)in the basal ganglion part of the brain. Methods Ninety-five patients with intracerebral hemorrhage were randomly divided into treatment group (microinvasive craniopuncture therapy) and control group (the clearance of hematoma by craniotomy with small bone flap). The main indexes of evaluation were the neurological impairment degree (NID) on the 14th day after treatment, activities of daily living (ADL) by the end of the third month, the incidence rate of complications, and the case fatality during 3 months. Results On the 14th day after treatment, there was no significant difference between the two groups in the NID and the ADL of patients. The incidence rate of respiratory tract infection, gastrointestinal hemorrhage, electrolyte disorder in treatment group [16.33% (8/49), 6.12% (3/49), 6.12% (3/49), respectively] was significantly reduced than those of control group [56.52% (26/46), 21.74%(10/46), 21.74% (10/46),respectively] during hospitalization (P < 0.05). By the end of the third month, there was significant difference in favorable outcomes (Barthel index 95-100) (χ~2 = 18.7524,P =0.0009) and in improving the ADL (MRS)(t =5.2723,P =0.0001) between the two groups [39.13% (18/46), 4.65% (2/43),respectively]. In ease fatality, there was no significant difference between the two groups [6.12% (3/49),6.52% (3/46),respectively]. Conclusion As compared with the clearance of hematoma by craniotomy with small bone flap, the microinvasive craniopuncture therapy can remarkably reduce the incidence of complications, and improve the ADL of patients with moderate cerebral hemorrhage (30-60 ml) in the basal ganglion, and decrease disability without increasing fatality.

Objective To evaluate the standardization of Meta-analyses on nephropathy published in Chinese journals.Methods By searching in WANFANG,VIP,CNKI databases and Chinese Biomedical Literature Database(CBM) as well as related Chinese journals,eligible Meta-analyses were enrolled and analyzed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) Statement and the MOOSE (Meta-analysis of Observational Studies in Epidemiology) Checklist.Results A total of 217 Meta-analyses were enrolled with 166 on randomized controlled trials (RCT) and 51 on observational studies.Based on the PRSIMA Statement,of the 166 Meta-analyses on RCT,51.8％(86 papers) were found with the complete research hypothesis,13.9％ (23) with the literature screening flow chart,15.7％ (26) with the subgroup analysis,53.0％ (88) with the publication bias analysis and 28.3％ (47) with the sensitivity analysis.According to the MOOSE Checklist,of the 51 Meta-analyses on observational studies,only 9.8％ (5) had done the statistical stability calculation,54.9％ (28) with the outlook of application,45.1％ (23) with the limitation of the study,2.0％ (1) with the quantitative analysis on potential bias and 17.6％ (9) with the suggestion for future studies.Conclusions Unclear hypothesis,limited methodological description,lack of in-depth analysis on heterogeneity and bias are the common defects in Meta-analyses published in Chinese journals on nephrology.

Objective To study whether citrate lock is superior to heparin lock in the prevention of catheter related infections,bleeding complications and catheter malfunctions among hemodialysis patients with tunneled catheters.Methods By searching in Pubmed,the Cochrane Library,EMBASE,Ovid,WanFang,VIP,CNKI and CBM databases as well as related journals,qualified randomized controlled trials were included in a Meta-analysis using Revman 5.0 and STATA 10.0 software.The endpoints included catheter related infection,bleeding complication,thrombolytic treatment,catheter removal for malfunction,catheter thrombosis and all-cause death.Results Fifteen randomized controlled trials were included with 1621 patients involved.Eight studies compared citrate alone with heparin lock,while 7 trials focused on citrate in combination with other antimicrobials.Pooled analysis demonstrated that incidence of catheter related infections in patients receiving citrate lock decreased by 47％ compared with those on heparin (RR=0.53,95％CI 0.36-0.77,P ＜ 0.01).Subgroup analysis by types of citrate lock indicated that all combined lock solutions of citrate and other antimicrobials (citrate + gentamicin,citrate + taurolidine,citrate + methylene blue +methylparaben + propylparaben) were superior to heparin lock in preventing catheter-related infections (P =0.01,0.04,0.01,respectively); citrate alone seemed to reduce catheter-related infection risk (RR =0.68),but no statistically significant difference was observed (95％CI 0.38-1.21,P=0.19).There were fewer patients with bleeding complications in citrate group (RR =0.53,95％ CI 0.34-0.S4,P ＜ 0.01),while citrate showed no advantage over heparin lock in terms of thrombolytic treatment (P =0.93),catheter removal for malfunction (P =0.35),catheter thrombosis (P =0.64) and all-cause death (P =0.35).Conclusions For hemodialysis patients with tunneled catheters,combined lock solutions of citrate and other antimicrobials,rather than citrate alone,are superior to heparin in preventing catheter related infections.Citrate locks are associated with less bleeding complications,and are comparable to heparin in the maintenance of catheter patency.

Objective To establish method of constructing lentiviral vectors to express microRNA (miRNA) ''tough decoy''(TuD)and to detect the effects of the TuD on cellular endogenous miRNA level and cellular phenotypes. Methods Two-step cloning strategy was utilized to first generate a universal miRNA TuD frame vector,followed by con-structing the TuD expression vector specially targeting miR-203. The package of the recombinant lentivirus was per-formed in 293T cells. Then the rat bone marrow mesenchymal stem cells(BM-MSCs)were infected by the miR-203 TuD expression lentivirus. The pSIH1-H1-copGFP vector was also packaged and the BM-MSCs infected by this lentivirus were served as control. Endogenous miR-203 level in BM-MSCs was measured by quantitative RT-PCR,and cellular vi-ability and apoptosis were detected by CCK-8 test and Annexin V-PI staining respectively. Results The miR-203 TuD expression vector was successfully constructed and inserted sequence was validated. At the 3rd,6th and 9th days after in-fected by the miR-203 TuD expression lentivirus,rat BM-MSCs exhibited a repressed endogenous miR-203 level. The miR-203 TuD also promoted viability and inhibited apoptosis of BM-MSCs. All these differences between miR-203 TuD group and control group were statistically significant. Conclusion The two-step cloning method for the construction of miRNA TuD expression vector is simple and efficient. The miRNA TuD can effectively suppress the level of the target miRNA and affect cellular phenotypes.

Objective To explore the efficacy of Krackow locking loop technique combined with the modified Kessler suture technique in the treatment of acute closed Achilles tendon rupture.Methods From January 2020 to January 2022,162 cases of acute closed Achilles tendon rupture were treated with Krackow locking loop technique combined with the modified Kessler suture technique.The patients were treated with the same postoperative rehabilitation plans.The American Orthopaedic Foot and Ankle Society(AOFAS)hindfoot score and Achilles Tendon Total Rupture Score(ATRS)were collected to evaluate the functions.Results The operation time was 24-40 min(mean,31.9±4.6 min).All incisions healed in one stage without infection or sural nerve injury.Complications occurred in 2 patients,including 1 case of deep venous thrombosis and 1 case of trauma-related re-rupture.The recovery time of ankle flexion and extension motion was4-12 weeks(mean,7.6±1.9 weeks),the recovery time of single-legged heel rise height on the affected side was 10-18 weeks(mean,13.3±1.8 weeks),and the recovery time of fast walking or jogging was 14-26 weeks(mean,19.1±1.8 weeks).The 162 patients was followed up for 14-25 months(mean,19.0 months).The AOFAS hindfoot score increased from(54.4±4.4)points preoperatively to(98.0±4.0)points at the last follow-up(t =-104.402,P =0.000).The ATRS score increased from(52.0±8.3)points preoperatively to(91.2±2.4)points at the last follow-up(t =-62.823,P = 0.000).Conclusions For young and middle-aged patients with acute closed Achilles tendon rupture,Krackow locking loop technique combined with the modified Kessler suture technique can achieve good clinical outcomes.Early functional exercise is required to return to work and life.

Sepsis-associated acute kidney injury (SA-AKI) is defined as the presence of acute kidney injury (AKI) in the context of sepsis. In the setting of genetic susceptibility, sepsis can lead to SA-AKI through various mechanisms. Based on differences in pathophysiological mechanisms, SA-AKI is categorized into different "endotypes" and manifests as distinct "subtypes". The combination of biomarkers and predictive models has the potential to early identify high-risk AKI patients and elucidate SA-AKI "endotypes". Volume resuscitation and blood purification are optimized strategies for SA-AKI treatment. Furthermore, clinical research on SA-AKI in children is promising.

Objective To explore the appropriate target ranges of blood glucose in intensive insulin therapy (ⅡT) for acute hyperglycemia following traumatic brain injury (TBI).Methods A randomized,open-label and controlled clinical trial was performed on 208 patients,admitted to our hospitals from Junuary 2014 to Sepember 2016.They were divided into ⅡT group (n=156),who were subdivided into slight (10.1-13.0 mmol/L),moderate (7.1-10.0 mmol/L),and strict (4.4-7.0 mmol/L) control blood glucose groups (n=52),and non-ⅡT group (n=52).Survival analysis 6 months after treatment was performed by Kaplan-Meier method.Modified Rankin scale (mRS) scores and Barthel index (BI),Glasgow Outcome scale (GOS) scores,concentrations of lactic acid in cerebrospinal fluid (CSF) and glycosylated hemoglobin,Glasgow coma scale (GCS) scores,Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) scores,Length of staying in intensive care unit (ICU) and incidence of adverse events were compared between the patients from different groups at different treatment times.Results Blood glucose level within 7 d of admission in patients ofⅡT group was in target ranges.The survival rate of patients from slight and moderate control blood glucose groups was significantly higher than that in the non-ⅡT group and strict control blood glucose group 6 months after treatment (x2=4.237,P=0.040;x2=5.621,P=0.018).As compared with those in the non-ⅡT group and strict control blood glucose group,the mRS scores 3 months after treatment were significantly decreased,and GOS scores and BI one,3 and 6 months after treatment were significantly increased in patients from slight and moderate control blood glucose groups (P＜0.05).As compared with that in the non-ⅡT group,and slight and moderate control blood glucose groups,the glycosylated hemoglobin level 7 d after treatment was significantly decreased in strict control blood glucose group (P＜0.05).As compared with those in the non-ⅡT group and strict control blood glucose group,the concentration of lactic acid in CSF 7 d after treatment,APACHE Ⅱ scores 7 and 14 d after treatment,length of staying in ICU and incidence of adverse events were significantly decreased in patients from slight and moderate control blood glucose groups (P＜0.05).The mean value of blood glucose in slight and moderate control blood glucose groups was (8.40±0.39) mmol/L.Conclusion Proper ⅡT improves the outcomes of TBI patients and (8.40±0.39) mmol/L are established as the target ranges in ⅡT for TBI.

Objective To explore the association of (cardiometabolic index , CMI ) and ( lipid accumulation product , LAP ) with the prevalence of hypertension in adults in Pingshan District, Shenzhen, and to evaluate the predictive value of CMI and LAP for the prevalence of hypertension. Methods A cross-sectional survey was conducted, in which 1000 permanent residents aged 18-69 years in Pingshan District, Shenzhen were randomly selected as survey subjects. The data were collected using questionnaires, physical measurements and blood tests, and the relationship between CMI, LAP and hypertension prevalence was analyzed using logistic regression models. Results A total of 987 subjects were included in the analysis, including 471 (47.72%) males and 516 (52.28%) females, with an average age of 40.9 ± 11.1 years. Subjects of different genders were divided into groups Q1 to Q4 according to quartiles of CMI and LAP, and the prevalence of hypertension increased with increasing levels of CMI and LAP in both men and women (P for trend < 0.001). Logistic regression analysis revealed that after adjusting for variables such as age and occupation, the OR for hypertension was 1.251 (1.025-1.526) and 1.685 (1.001-2.836) for men and women, respectively, for each standard deviation increase in CMI; the OR for hypertension was 3.519 (1.343-9.222) for men in the Q4 group, compared to the CMI subgroup Q1. For each standard deviation increase in LAP, the ORs for hypertension were 1.355 (1.089-1.686) and 1.825 (1.023-3.254) for men and women, respectively; compared to LAP subgroup Q1, the ORs for hypertension in the male Q3 and Q4 groups were 2.554 (1.103-5.909) and 5.322 (2.393-11.834), while the OR for hypertension in the female Q4 group was 2.906 (1.096-7.703). ROC analysis revealed that the area under the curve (AUC) for CMI, LAP, and BMI was 0.671, 0.704, and 0.702 for males, and 0.660, 0.722, and 0.697 for females, respectively. The AUC for LAP was greater than that for CMI for different genders (P < 0.01). Conclusion The greater the CMI and LAP values in adults in Pingshan District, Shenzhen , the higher the prevalence of hypertension. CMI and LAP have certain values in predicting the prevalence of hypertension.
