SCr and BUN of those patients with abnormal renal functions were all improved significantly after herbal treatment (P

【Objective】In-vitro antibacterial activity of the combination of Herba Violae(HV)and Herba Taraxaci(HT)in different proportions was compared and analyzed for the optimization of the combination proportion of Herba Violae and Herba Taraxaci and the influencing factors.【Methods】The minimum inhibitory concentration(MIC)of the combination of HV and HT was determined by agar double dilution method and the minimum bactericidal concentration(MBC)by broth dilution method,and bactericidal curve was traced.Meanwhile,the resistance of the combination of HV and HT induced by sub-inhibitory concentration was analyzed,and the influencing factors of in-vitro antibacterial activity were investigated.【Results】The combination of HV and HT in the proportion of 1∶4 had a better antibacterial activity on four kinds of gram-positive bacteria and on four kinds of gramnegative bacteria,and exerted an bactericidal effect on Escherichia coli and Klebsiella Pneumoniae(both MBC_(50)/MIC_(50) and MBC_(90)/MIC_(90) being 2).The bactericidal curve showed that 2?Log cfu/mL bacteria strain could be killed by the combination of the proportion being 1∶4 at 8~(th) hour,the effect being superior to that of other two combinations.Inoculation dosage,serum amount and pH value had no effect on in-vitro antibacterial activity.【Conclusion】The combination of HV and HT in the proportion of 1∶4 has a better antibacterial activity.

Objective To analyse the suspected hereditary non-polyposis colorectal cancer (HNPCC) in mismatch repair protein (MMR) expression of hMLH1 and hMSH2. Methods Immunohistochemical staining method was used for the detection of hMLH1 and hMSH2 protein expression in 193 cases suspected HNPCC patients, the deletion of MMR proteins was identified as highly suspected HNPCC cases. Results Of the 193 patients with suspected HNPCC hMLH1/hMSH2 abnormal expression rate was 29.02%; ≤30 years old was 40%, 31 ~ 40 years old was 28.05%, 41 ~ 50 years old was 28.71%,3 suspected HNPCC showed the deletion of hMLH1/hMSH2 protein expression at the same time ,; In the right colon , the left half colon and rectal anomaly detection rates were 40.74%, 32.65%and 18.89%; hMLH1/hMSH2 deletion was 46.15%with family history. Conclusions The deletion of MMR protein is closely related to age,site and family history in suspected HNPCC, and the deletion of hMLH1 is an important factor to induce early-set colorectal cancer. The deletion of hMLH1/hMSH2 at the same time indicates that hMLH1/hMSH2 genes may play important role in the incidence of HNPCC.

Methods 120 inpatients with severe brain injury were divided into 4 groups according to the disease course. Group 1: <1 month; Group 2: 1~3 months, Group 3: 3~6 months; Group 4: 6~12 months. Fugl-Meyer Assessment (FMA) and Modified Barthel Index (MBI) were assessed before and 2 months after treatment. Results All groups were with better effects after treatment than before (P<0.05), early system rehabilitation had better effects especially for Group 1 (P<0.05). Conclusion Early rehabilitation treatment can facilitate the recovery of patients with severe brain injury

Purpose: In non-metastatic prostate cancer (nmPCa) setting, it is important to early identify the patients at risk of biochemical recurrence (BCR) for immediate postoperative intervention. Our study aimed to evaluate the potential clinical utility of circulating tumor DNA (ctDNA) for predicting disease recurrence. Materials and Methods: This real-world observational study evaluated 161 cases of nmPCa undergoing next-generation sequencing at our institution. A total of 139 ctDNA samples and 31 biopsied tumor tissue underwent genomic profiling. The study endpoint was BCR after radical prostatectomy. Relationships between the ctDNA status and the biochemical progression-free survival (bPFS) were analyzed by log-rank test and multivariate Cox regression. Results: Of 161 enrolled patients, 19 (11.8%) harbored deleterious alterations in NCOR2, followed by BRCA2 (3.7%), ATR (2.5%), and CDK12 (2.5%). Of available pre-operative blood samples (n=139), ctDNA was detectable in 91 (65.5%). Until last follow-up, 56 of 68 patients (85.3%) with detectable ctDNA had achieved BCR, whereas only eight of 39 patients (20.5%) with undetectable ctDNA had achieved BCR. Patients who had undetectable ctDNA experienced significantly longer bPFS compared with those who had detectable ctDNA (not available vs. 8.2 months; hazard ratio, 0.14; p < 0.01). Pre-operative ctDNA status was a significant prognostic factor of disease recurrence. Conclusion Pre-operative ctDNA detection could identify patients at high risk of recurrence and has the potential to inform immediate postoperative interventions, but these approaches remain to be validated in prospective studies. ctDNA studies can provide insights into accurate monitoring and precise treatment rather than simply following routine clinical care.

BACKGROUNDLow molecular weight heparin (LMWH), as one of anticoagulant drugs, has been used for the treatment of chronic obstructive pulmonary disease (COPD) with prethrombotic state, but the specific use time is unclear. The aim of the study is to observe the effect of LMWH at two different periods of prethrombotic state in COPD in rats and to find the optimal time to use LMWH.

METHODSForty Wistar rats were randomly divided into 4 groups: normal control, raised for 55 days without any treatment; COPD control without LMWH, cigarette inhalation plus intratracheal instillation of lipopolysaccharide and hypodermic injection of normal saline once a day for 10 days; COPD control given LMWH 150 U/kg subcutaneous injection, once a day for 10 days starting day 15 (LMWH-d15); COPD control given LMWH 150 U/kg subcutaneous injection, once a day for 10 days starting day 29 (LMWH-d29).

RESULTSComparing LMWH-d15 with LMWH-d29, plasma viscosity, whole blood viscosity, von Willebrand factor, serum fibrinogen, plasminogen activator inhibitor-1 and fibrin D-dimer were each significantly reduced; but thrombin plasminogen activator increased significantly whilst arterial PO2 and PCO2 improved significantly.

CONCLUSIONThe better time to use LMWH is the time when coagulation and fibrinolytic indices begin to change in COPD.
