Objective To observe the clinical role of Qiliqiangxin capsules uniting conventional western medicine interfering with chronic heart failure(CHF).Methods 61 cases of CHF were randomly recruited into a control group(31 cases)and a treatment group(30 cases).The control group was treated with conventional anti-hean failure treatment,and the treatment group was added Qiliqiangxin capsules on the treatment of the control group.After having been treated for 2 courses (fonr weeks),such indexes as clinical efficacy,body weigbt,urine volume,6 min walking distance(6MWD),electrocardiogram,and cardiac ultrasound were measured for both groups.Results The overall efficiency of cardiac function was 93.33%for the treatment group and 74.19%for the control group.There was significant difierence between the two groups(χ~2=4.07985,P＜0.05).The enhance rate of left ventricular ejection fraction(LVEF)was(16±4)%in the treatment group as compared to(11±3)%in the control group,also showing statistical difierence between the two groups(t=5.509,P＜0.001).Conclusion Qiliqiangxin capsules combined with conventional western medicine could effectively improve the cardiac function,LVEE clinical symptoms,and quality of life in the patients with ehronic heart failure.

objectlve To investigate the efficacy of continuous low-dose fluorouracil with cetuximab for antiangiogenic effect on colon carcinoma xenograft,and test its antitumor effect and toxicity.Methods Balb/c mice bearing CT-26 colon carcinoma xenograft were randomly divided into five groups,receiving low-dose metronomic(LDM)fluorouracil,maximum tolerated dose(MTD)fluorouracil,cetuximab,LDM fluorouracil with cetuximab therapy and saline respectively.Tumor growth,weight loss,peripheral white blood cell counts and survival of mice were monitoted.At the end of experiment,tumors were resected for tumor microvascular density(MVD)by immunofluorescence staining. Results Tumor growth inhibition was found in mice receiving LDM fluorouracil therapy and combined therapy,without significant body weight loss or leukopenia,and the survival of mice was remarkably prolonged,compared with mice receiving MTD fluorouracil or cetuximab therapy,and the antitumor effects of the combined therapy was stronger than that of the fluorouracil LDM therapy.LDM treatment and combine treatment led to statistically significant(P＜0.05)55%and 71%reduction in tumor growth,as well as 73%and 77% reduction in tumor microvessel density compared with the control respectively.Additonally,tunnel staining shows no significant difference between these treatment groups. Conclusion Continuous low-dose regimen of fluorouracil with cetuximab can significantly increase the therapeutic activity with decreased toxicity and prolonged animal survival bearing implanted colon cancer.

Objective To investigate the outcome between endoscopically assisted and routine anterior transposition of the ulnar nerve for treatment of cubital tunnel syndrome.Methods From Februray 2008 to June 2010, forty-four patients with cubital tunnel syndrome were treated with routine anterior subcutaneous transposition (routine group,28 cases) and endoscopically assisted anterior subcutaneous transposition (endoscope group,16 cases).The operate time,drug administration,scar and postoperative hospital stay were compared.The patients were followed 1-12 month postoperatively,postoperative time back to work and function of ulner nerve were recorded.Results The results of endoscope group were as follows: operative time was (67.20 ± 19.69)min; postoperative scar length was (1.5％ ± 0.58) cm; rate of administration of anodyne was 6.3％; postoperative hospital stay was (2.4％ ± 1.42) days; postoperative time back to work,(14.6 ± 4.69)days; the results of open surgery group were as follows:operative time (62.8％ ± 11.06) min; postoperative scar length was (8.7％ ± 1.42) cm; rate of administration of anodyne was 42.8％; postoperative hospital stay was (5.7％ ± 2.53) days; postoperative time back to work was (29.40 ± 8.75) days; all differences of the results were significant between two groups (P ＜ 0.05).According to function of ulner nerve scoring system,one year postoperatively, excellent or good results were 82.14％ in routine group and 81.25％ in endoscope group,no significant difference between two groups (P ＞ 0.05). Conclusion Compared with routine anterior transposition of the ulnar nerve,endoscopically assisted anterior transposition has the following advantages: smaller incision and less tissue damage,less postoperative pain and sooner returning to work.And similar outcome was achieved from the two group.

Due to the influence of immunosuppression, nerve injury and other comprehensive factors, the overall incidence of gastrointestinal complications after lung transplantation is relatively high, which can cause drug absorption disorder and chronic rejection. In recent years, more and more studies have been conducted on these complications. However, due to the great difference of the incidence of gastrointestinal complications among lung transplantation centers, clinicians lack of understanding of these. In this article, the general status, common types and risk factors of gastrointestinal complications after lung transplantation were reviewed, aiming to provide reference for comprehensive management of gastrointestinal complications after lung transplantation.

Due to the impact of COVID-19, the online problem-based learning (PBL) teaching mode was first implemented based on the curriculum integration of basic medicine and clinical medicine in our university in 2020. A total of 357 eight-year program clinical medicine students from three grades participated in the online PBL courses. The students have had related skills and knowledge of integration curriculum, and the teachers have carried out sufficient analysis of learning situation, preparation of software and hardware, as well as teaching design. Teachers and students has communicated with each other smoothly and cooperated closely through the Tencent Conference software platform, therefore this teaching mode has gained better feedback among students, with higher satisfaction of courses and significantly improved students' learning enthusiasm. The curriculum integration has laid the foundation for the case design and application of online PBL teaching, while the success of online PBL teaching has also reflected the original intention of curriculum integration reform.

OBJECTIVETo perform a retrospective cohort study in order to determine the differences in short-term curative effect of ribavirin in combination with interferon alfa (IFNa)-2a vs. pegylated (Peg)-IFNa-2a in patients with chronic hepatitis C (CHC).

METHODSOne-hundred-and-eighty-eight treatment of the CHC patients who were administered combination therapy of ribavirin with IFNa from 2010 to 2012. One-hundred-and-thirty-three of the patients received the therapy with IFNa-2a and the remaining 55 received Peg-IFNa-2a. Hepatitis C virus (HCV) load and levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured at treatment weeks 4, 12, 24, and 48. Adverse reactions were recorded. Differences between the groups were assessed by statistical analysis.

RESULTSThe patients in the Peg-IFNa-2a group and the IFNa-2a group showed no significant difference in sex distribution, age, smoking habits, or drinking habits at baseline (all P more than 0.05). Both antiviral therapies significantly reduced the HCV load and levels of ALT and AST (baseline levels vs. all treatment weeks examined, P less than 0.05); however, the reduction in the HCV load at week 4 was significantly more robust with the Peg-IFNa-2a therapy (2.96 ± 0.66) log10 IU/ ml vs. (3.47 ± 1.42)1og10 IU/ml; F =4.14, P=0.04). The Peg-IFNa-2a group also showed a significant higher rate of rapid virological response (RVR) than the IFNa-2a group (72.72% vs .57.14%; x²=4.37, P=0.04), but there were no statistically significant differences found between the two groups for early virological response rate (EVR), endpoint antiviral treatment virologic response rate (ETR), biochemical response rate, or rate of adverse reactions (all P more than 0.05).

CONCLUSIONRibavirin in combination with Peg-IFNa-2a produces a better RVR than in combination with IFNa-2a .Yet, the EVR, ETR, biochemical response rate, and rate of adverse reactions is similar for the two forms of IFNa-2a. Further studies are required to determine the potential superiority of Peg-IFNa-2a for a long-term curative effect.

Objective:To identify the pathogenic gene and inheritance pattern in a pedigree of congenital iris coloboma with congenital cataract.Methods:The method of pedigree investigation was adopted.A pedigree of congenital iris coloboma with congenital cataract was collected by Yunnan Disabled Rehabilitation Center and the 2nd Afliated Hospital of Kunming Medical University in February 2020.Ophthalmic examinations were carried out on the female proband, her parents, her children and her husband, and the clinical diagnosis was made.Genomic DNA was extracted from peripheral blood samples collected from the family members.The suspected pathogenic gene in the proband and her husband was screened by whole exome sequencing and was identified by bioinformatics analysis.The amino acid conservation was analyzed by UGENE software.The impact of the mutation on protein translation was predicted using MutationTaster software.The pathogenicity of the mutation was assessed according to the American College of Medical Genetics (ACMG) Standards and Guidelines.Pathogenic gene and mutations were verified by Sanger sequencing.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the 2nd Afliated Hospital of Kunming Medical University (No.PJ-2020-61).Written informed consent was obtained from each subject or custodian.Results:The proband showed large iris defects in both eyes with only a small amount of observable iris tissue in the periphery, lens cortical opacity and posterior capsule opacification, accompanied by nystagmus.A novel heterozygous frameshift variation c. 415dupA (p.R139fs) was located in exon 8 of PAX6 gene, and the variation was conservative across multiple species.The variation was in the highly conserved region of PAX6 gene and caused the dysfunction of PAX6 protein.The variation was graded as PVS1+ PM2+ PP1, a pathogenic variation, based on ACMG guidelines.The pedigree was consistent with co-segregation, indicating that the novel variation was pathogenic.The proband and her children were diagnosed, but her parents were phenotypically normal, in accordance with autosomal dominant inheritance. Conclusions:The novel frameshift variation c.415dupA (p.R139fs) on the exon 8 of PAX6 gene is responsible for congenital iris coloboma with congenital cataract in the pedigree.This is the first report of this novel variation in PAX6 gene.
