[Objective]To introduce the old Chinese medicine Professor FU Weimin 's experience in diagnosis and treatment of peripheral facial paralysis. [Methods]Firstly, analyze and summarize the relevant medical records. Secondly, to briefly elaborate that the professor FU Weimin believes the overall concept ,adheres to the syndrome differentiation as a guide, and how he treats peripheral facial paralysis by syndrome differentiation.[Results]He thinks that lack of righteousness, context is empty, Wei is not solid for the fundamental pathogenesis. More importantly, vein paralysis is a pathological feature. Treatment is from the wind, sputum, blood stasis and blood deficiency and clinical medication is unique. According to the course of staging , Professor FU stresses the precise discrimination and drugs have their own characteristics. Professor insists on people-oriented and makes a significant contribution.[Conclusion]Professor FU Weimin has a systematic understanding of the pathologic mechanism of peripheral facial paralysis, syndrome differentiation and clinical experience of prescription drugs and has made a good therapeutic effect in clinical application, which is worthy of popularizing.

Objective To investigate the sustained release of BSA from chitosan-OREC/BSA films coated mats in vitro.Methods The negatively charged cellulose acetate (CA) fibrous mats were modified with multilayers of the positively charged chitosan or chitosan-OREC intercalated composites and the negatively charged bovine serum albumin (BSA) via electrostatic layer-by-layer (LBL) self-assembly technique.The adsorption and rinsing steps were repeated until the desired number of deposition bilayers was obtained.The in vitro BSA encapsulation and release experiments demonstrated that OREC could affect the degree of protein loading capacity and release ficiency of the LBL films coating.Results In the pH-gradient release assay,only a small amount of BSA was released from the mats in 1 h.As the time increased,the release rate of BSA of all the samples gradually went up to the maximum data within 8 h.For the samples with identical number of bilayers and record time,obvious increasing of the release amount could be seen in pH 7.4,in comparison with pH 1.2.Besides,doubling bilayers film-coated mats generally.Meanwhile,it was slightly distinguishable between 5 and 5.5 as well as 10 and 10.5 bilayers (t=0.651～ 1.324,P＞0.05).Interestingly,it could be seen that protein release of the chitosan-OREC/BSA films coated mats remarkably increased compared with that of chitosan/BSA films coated mats(t=2.264～ 2.305,P＜0.05).Conclusion The release of protein in the initial time could be controlled by adjusting the number of deposition bilayers,the outmost layer and the composition of coating bilayers.

Objective To investigate the effect of hepatitis C virus (HCV) genotype on antiviral therapy in patients with human immunodeficiency virus (HIV)/HCV coinfection in Henan province.Methods A total of 129 patients were coinfected with HIV and HCV, among whom, 70 were HCV 1b genotype and 57 HCV 2a genotype.And 131 patients were HIV single infection.Immunological failure rate, virological suppression, CD4+ T lymphocyte counts and liver and renal function after antiretroviral therapy (ART) were compared among the three groups.Flow cytometry was used to count CD4+ T lymphocytes and polymerase chain reaction amplification was used to detect HIV RNA.The liver and renal function were tested by automatic biochemical analysis.Statistical analysis was conducted by χ2 test, analysis of variance and LSD-t method.ResultsImmunological failure rate in HCV 1b group, HCV 2a group and HIV single infection group were 7.14% (5/70), 15.79% (9/57) and 9.92% (13/131), respectively.There was no significant statistical difference among the three groups (χ2=2.59, P>0.05).The CD4+ T lymphocyte counts in three groups were (614±258), (529±245), and (518±243) cells/μL, respectively.The difference was statistically significant (F=3.17, P<0.05).The virus inhibition rates of three groups were 87.0% (HCV 1b), 78.2% (HCV 2a), and 82.3% (HIV single infection).The HIV virus failure rates were 8.6% (HCV 1b), 14.5% (HCV 2a), and 13.1% (HIV single infection).There was no significant difference among three groups (χ2=1.967, P>0.05).The levels of aspartate transaminase, alanine aminotransferase and total bilirubin in HCV 1b group and HCV 2a group were all significantly higher than those in HIV single infection group (F=27.38, 15.22 and 7.33, respectively, all P<0.05), while there was no significant difference between HCV 1b and HCV 2a groups (t=1.27, 0.29 and 1.59, respectively, all P>0.05).Conclusions The main HCV genotypes in patients with HIV/HCV coinfection by blood transmission are HCV 1b and HCV 2a in Henan province.HIV/HCV coinfection does not affect the effect of ART, but could aggravate the liver damage in acquired immune deficiency syndrome patients.

Objective:To analyze the clinical characteristics of primary acute myeloid leukemia (AML) (non-M3 type) in children suffering from different levels of platelet count(PLT).Methods:In the Tumor Hospital of Zhengzhou University from January 2014 to December 2018, laboratory and clinical data of 247 de novo primary AML pediatric patients were retrospectively reviewed.According to the PLT before treatment, patients were divided into very low platelet group (VLG), low platelet group (LG) and non-lowing platelet group (NLG), with<50×10 9/L, ≥50×10 9/L but <125×10 9/L and ≥125×10 9/L as the boundaries.All patients were followed up until June 30, 2019.Meanwhile, the follow-up data was obtained by consulting medical records or by telephone.SPSS 17.0 software was applied for data analysis. Results:In general clinical features, a different group of hemoglobin (Hb) content, fusion gene AML- ETO and clinical risk stratification were statistically significant in different PLT groups ( χ2=11.270, 12.115 and 12.848, respectively, all P<0.05). However, the differences of other indicators in different groups of PLT were not statistically significant (all P>0.05). There were no statistically significant differences in terms of 3-year disease-free survival(DFS) rate (59.3%, 36.3%, 50.4%) among the 3 groups (all P>0.05). The median total survival(OS)time(40.5 months)and 3-year OS rate(41.0%) of NLG patients were significantly higher than those of VLG(23.1 months, 30.1%)and LG(14.1 months, 18.2%)patients, with statistically significant differences( χ2=7.798 and 6.553, respectively, all P<0.05). The univariate analysis of gender, white blood cell(WBC), Hb, PLT, lactic dehydrogenase(LDH), FLT3-ITD, NPM1, DNMT3A, CEPBA, C-KIT, AML-ETO, molecular genetic prognosis, complete remission(CR), and hemopoietic stem cell transplantation(HSCT) displayed that DNMT3A mutation was an adverse factor that affects patients′ OS ( χ2 =5.834, P<0.05), and the positive factors that influences OS were non-reducing PLT before treatment, and obtaining CR and subsequent HSCT ( χ2=7.798, 79.168, and 31.337, respectively, all P<0.05). Multi-factor analysis revealed that the independent protective factors that affect patients′ OS were the non-reducing PLT before treatment, and obtaining CR and subsequent HSCT( Wald=42.760, 15.918, and 10.183, respectively, all P<0.05). Conclusions:Before treatment, non-reducing PLT is a protective factor for primary childhood AML patients, and the prognosis is satisfying.
