OBJECTIVE: To evaluate the effect of partial inferior turbinectomy in treating inferior nasal meatus epistaxis. METHOD: Twenty one case of inferior nasal meatus epistaxis were subjected to submucoperiosteous partial inferior turbinectomy and nasal cavity plugging under nasal endoscopy Its effect were analyzed. RESULT: All patients cured and discharged after 3-7 days. After 2 months to 3 years of follow up, no recurrence were seen. CONCLUSION Submucoperiosteous partial inferior turbinectomy under nasal endoscopy is an effective and reliable method in treating inferior nasal meatus epistaxis.

Objective:To construct the recombinant prokaryotic plasmid to express HCV HLA-A2 restricted multi-CTL epitopes and to purify the fused protein for antigenic analysis.Methods:The human ubiquitin gene and multi-CTL epitopes gene was synthesized respectively,and digested by restrict enzyme before being cloned into pRSET-A.Then it was transformed into E.coli DH5α and the positive recombinant plasmid named pRSET-Ub-Mep was sequenced.Target protein was distinctly expressed after transformed into E.coli BL21 and induced with IPTG.Thus the protein was scanned and purified on Ni~(2+)-NTA column as well as Western blot performed after solubility analysis.Results:The recombinant plasmid pRSET-Ub-Mep was successfully constructed and it could efficiently express the target gene.Protein production was mainly in inclusion body and could be purified through Ni~(2+)-NTA column.The purified protein kept the antigen activity.Conclusion:The gene encoding for HCV HLA-A2-restricted multi-CTL epitopes is efficiently expressed and the target protein is purified,which establishes a foundation of further research to evaluate the cellular immune response induced by the target gene.

Objective To observe the clinical effect of a modified version of constraint-induced movement therapy(MCIMT)on motor recovery in the upper extremities of stroke patients. Methods Twenty-seven stroke patients were randomly divided into a treatment group(n=14)and a routine group(n=13).The Bobath approach and functional arm exercise were administered to the patients in the routine group(2 h/d,5 times a week)for ten weeks.The MCIMT administered to the treatment group involved restriction of the functional arm by a sling during 90%of waking time and during training(by shaping)of the affected extremity(1 hour per day,three times a week)in addition to activities of daily living exercise for at least 2 hours every day.The main outcome measures were the ten items of the simplified test for evaluating hand function(STEF)and Wolf's Motor Function Test(WMFT). Results No significant difference was observed between the 2 groups with regard to WMFT and STEF scores before treatment.After treatment,both groups had improved their WMFT and STEF scores significantly,but there was a significant difference between the treatment and the control groups with regard to WMFT scores and 7 items of the STEF test. Conclusion Modified constraint-induced movement therapy is effective not only for promoting motor recovery of the upper extremity,but also for improving the flexibility and velocity of movement instroke patients.

Objective To explore the related influencing factors of androgenic alopecia(AGA)in young women(FAGA).Methods A total of 296 cases of FAGA initially diagnosed in the dermatology clinic of this hospital from January 2022 to January 2023 were selected as the observation group,and 296 young women without suffering from FAGA in the physical examination of this hospital at the same time were selected as the control group.The clinical data were compared between the two groups and the influencing factors causing FAGA in young women were analyzed.Results The familial inheritance history,often staying up,sleep disor-der,like to eat high carbohydrate food,like to eat high fat food,high mental stress,going on a diet,irregular menstruation,childbearing history and complicating other diseases had statistical differences between the two groups(P＜0.05).The multivariate logistic regression analysis results showed that the familial inheritance history,often staying up,sleep disorder,like to eat high carbohydrate food,like to eat high fat food,high men-tal stress,going on a diet,irregular menstruation,childbearing history and complicating other diseases were the independent risk factors leading to FAGA(P＜0.05).Conclusion It is necessary to do a good job in the complicating disease screening of young female hair loss groups and pay attention to the related risk factors.

【Objective】 To analyze the HIV-, HCV- and HBV- NAT yield rate in different areas of Henan province, so as to provide the basis for disease prevention and control as well as the establishment of a unified quality control standard for nucleic acid testing(NAT) in the Henan province. 【Methods】 The number and prevalence of NAT yielding samples with isolated infectious virus, namely HIV, HCV and HBV, in 18 blood stations in Henan province from 2017~2019, as well as the trends were analyzed. The NAT quality of each laboratory and each testing system was analyzed according to the ratio of reactive individual donation(ID) results to reactive minipools(MP). 【Results】 The HBV, HCV and HIV ID-NAT yield numbers in 3 501 251 blood donations were HBV 2 606(74/100 000), HCV 21 (0.63/100 000), and HIV 34(1.00/100 000). The HBV ID-NAT yield rate showed an upward trend in the whole province from 2017 to 2019, while the prevalence of HIV and HCV ID-NAT yield didn′t differ significantly during three years. 5 kinds of NAT detection systems were applied in 18 blood centers. among which Ⅰ, Ⅱ, Ⅳ and Ⅴ were triplex detection systems. 2661 ID-reactive samples were implicated in 5 595 MP-reactive samples, with a resolution rate of 47.56%. The resolution rate of triplex NAT system Ⅰ, Ⅱ, Ⅳ and Ⅳ was 39.63%~47.95%, 40.43%~54.36%, 51.61% and 70.00%~45.45%, respectively. An upward trend in triplex NAT resolution rate was observed in 8 laboratories, i. e.B, D, E, F, I, K, L and Q, and an descending trend in A and C. The NAT system Ⅲ, a ID-NAT system, was used only by laboratory C, presenting a NAT-yield rate of 0.19% (282/145 474) and resolution rate of 46.45% (131/282). 【Conclusion】 The majority of NAT-yield of one infectious virus in Henan province is HBV, presenting annual increasing trend. The quality management of NAT laboratories should be strengthened as the divergence was seen in the performance of different NAT laboratories.

【Objective】 To analyze the cause of single-ELISA reactive of four blood screening items in 18 blood stations in Henan, so as to provide the basis for improving the quality of blood screening. 【Methods】 The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP of 18 blood station laboratories in Henan throughout 2019 was calculated, and the causes were analyzed according to different ELISA reagent combinations and gray area settings in each laboratory. 【Results】 The overall single-ELISA reactive rates of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP were 1.740(2 154/1 237 789), 0.564‰(698/1 237 789), 1.421‰(1 759/1 237 789) and 1.561‰(1 932/1 237 789), respectively, showing significant differences by detection items (P <0.05). Person correlation analysis showed that the single-ELISA reactive rate was independent of the gray area settings.but dependent on laboratories and reagent combinations. The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP in D laboratory was the highest and higher than that in other labs using the same reagent.The laboratories with high HBsAg single-ELISA reactive rate were mostly those using a combination of imported reagents and domestic reagents, including the top 6 laboratories. The laboratories with high anti-HCV single-ELISA reactive rate were mostly those using certain domestic reagents. No obvious rules was noticed by single-ELISA reactive for anti-HIV. Laboratories with high anti-TP single-ELISA reactive rate were mostly those using combination 4. 【Conclusion】 The HBsAg single-ELISA reactive rate was the highest in the four blood screening items of blood station laboratories in Henan. The single-ELISA reactive rate is related to the laboratory itself and the reagent manufacturer, suggesting that laboratory quality control should be strengthened and proper reagent combination should be selected to reduce the waste of blood.
