Objective To observe the effects of hand function training with continuous passive motion (CPM) on hand spasm and function of the hemiplegic patients.Methods 60 hemiplegic patients after stroke or brain trauma and with hand spasm were randomly divided into the treatment group and control group with 30 cases in each group. The cases in the treatment group were treated mainly with the method of CPM together with the routine rehabilitation procedures, while the those in the control group were only treated with the routine rehabilitation procedures. The changes of hand spasm and function of two groups were observed.Results After four weeks' treatment, the efficacy of the treatment group was obviously better than that of the control group ( P<0.05).Conclusion The rehabilitation training is an effective method for treatment of hemiplegia, and CPM is an important auxiliary method in the treatment. These two Methods combined together can shorten the course of treatment, and strengthen cure efficacy.

Objective To analyze the expressions of tumor stem cell markers Lgr5 and CD44 in esophageal carcinoma and its clinical pathological significance.Methods A total of 108 cases of patients with esophageal cancer, 35 cases of stage Ⅱ, 40 cases of stage Ⅲ, 4 cases of stage Ⅳ. After tumor specimens were stained, the expressions of Lgr5 and CD44 in esophageal cancer tissue were detected and its relationship with the clinical features were analyzed.Results There were relations between expressions of Lgr5 and CD44 in esophageal cancer tissue and clinical staging, the later the stageing, the higher expression rate of Lgr5 and CD44, but there was no significant differece with Chi-square test. The Spearman correlation analysis showed there was no correlation between Lgr5 or CD44 and esophageal cancer condition. Conclusion CD44 and Lgr5 are highly expressed in esophageal cancer tissue, but the correlation between CD44 and Lgr5 expression and esophageal cancer condition is uncertain.

BACKGROUND:Bone marrow mesenchymal stem cells have particularly applied prospects in tissue engineering. However, the death of transplanted cells limits the tissue regeneration. To search a new drug of anti-free radicals and protecting bone marrow mesenchymal stem cells is of great significance. OBJECTIVE:To investigate the protective effects of mangiferin on bone marrow mesenchymal stem cells against hypoxia. METHODS:Rat bone marrow mesenchymal stem cells were cultured in vitro and hypoxia cellmodel was established by cobalt chloride. cells were divided into normal control group, hypoxia group (treated with cobalt chloride), and mangiferin groups (cobalt chloride+20, 40, 80, 160 μmol/L mangiferin). After 12 and 24 hours of hypoxia, superoxide dismutase, malondialdehyde, and catalase levels in the cellsupernatant were determined. After 3, 6, 12, 24 hours of hypoxia, reactive oxygen species change was detected in each group. RESULTS AND CONCLUSION:Mangiferin significantly improved the survival rate of bone marrow mesenchymal stem cells exposed to hypoxia, increased the intracellular superoxide dismutase and catalase activities, decreased intracellular malondialdehyde and reactive oxygen species levels, thereby effectively protecting bone marrow mesenchymal stem cells against hypoxia. These findings indicate that mangiferin has effective protection against hypoxia and strong antioxidant ability, and can significantly reduce oxidative damage.

Pancreatic tuberculosis (PTB) is a rare,chronic,specific and infectious disease which is generally secondary to tuberculosis at the common sites of pancreas,and it has a high misdiagnosis rate due to the hidden onset and nonspecific symptoms of PTB.A patient with PTB was admitted to the First Affiliated Hospital of Zhengzhou University in June 2014.Before operation,the space-occupying lesions of the head of pancreas were detected by preoperative imaging examination,and the patient was regarded as with pancreatic cancer.Intraoperative exploration showed cystic duct involvement,and the granulomatous inflammation was detected by rapid pathological examination using frozen section technique,after that the patient received granuloma resection+cholecystectomy according to suspected PTB.The diagnosis of PTB was confirmed by postoperative pathological examination,and the patient received liver-protective and anti-tuberculosis treatments after discharge.

BACKGROUND:Hypoxic death limits application of cells in transplantation and tissue regeneration.
OBJECTIVE:To investigate the protective effects of mangiferin on bone marrow-derived mesenchymal stem cells against hypoxia injury-induced apoptosis resulted from cobalt chloride.
METHODS:Rat bone marrow-derived mesenchymal stem cells were in vitro cultured and hypoxia cellmodel was established by cobalt chloride. Model cells were treated with mangiferin. Protective effects of mangiferin were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide;cellapoptosis and mitochondrial membrane potential were detected using flow cytometry.
RESULTS AND CONCLUSION:Cobalt chloride significantly inhibited growth of bone marrow-derived mesenchymal stem cells in a dose-dependent manner. The apoptosis rate of cells was (42.49±3.96)%after treated with 200μmol/L cobalt chloride for 12 hours, (46.37±4.49)%after treated for 24 hours. With increasing concentration of mangiferin, apoptosis of bone marrow-derived mesenchymal stem cells in hypoxic model was gradual y reduced (P<0.01), indicating that mangiferin has a protective effect in a concentration-dependent manner on rat bone marrow-derived mesenchymal stem cells in hypoxic injury. Cobalt chloride can induce hypoxic model successful y in bone marrow-derived mesenchymal stem cells. There are some advantages of accurate dose control, no special equipment requirements, and easy operation. Mangiferin can effectively inhibit bone marrow-derived mesenchymal stem cells apoptosis under hypoxic injury.

BACKGROUND:Recently, the clinical repair methods of irregular wound on fingers primarily include local pedicled flap and free mini-flap of upper extremities or lower extremities.
OBJECTIVE:To discuss the application of free mini-flap derived from upper limb in repairing the wound on fingers.
METHODS:From December 2010 to February 2014, 12 patients with irregular wounds on 12 fingers were selected from Department of Traumatic Orthopaedics and Hand Surgery, First Affiliated Hospital of Guangxi Medical University, China. The size of wounds ranged from 1.5 cm × 2.0 cm to 3.0 cm × 4.5 cm with different degrees of bone or tendon exposure. After the debridement, 12 patients were treated by free mini-flaps of upper limb. The donor sites were directly sutured.
RESULTS AND CONCLUSION:Among the 12 patients, al the wounds at recipient and donor sites were healed at stage I, and the free mini-flags survival completely. Al of patients were fol owed up for 3-6 months (average 4.5 months). Free mini-flags had good appearance and needn’t undergo secondary trimming. The active motion of fingers was improved dominantly. According to the criteria of Hand Surgery Association Society of Chinese Medical Association Society for the function evaluation of upper limb, three cases were excellent, eight were good, and only one was bad. The excellent and good rate was 91%. Free mini-flaps of upper limb are an ideal method for repair of wounds on fingers. It has no injury to normal tissue in hands, donor site is very secluded, and the short-term curative effect is good.

Objective To study the expression of angiopoietin-like protein 3(ANGPTL3) mRNA successively in kidney of adriamycin (ADR)-induced nephrotic rats during the development of proteinuria, and to disclose the possible assosiation of ANGPTL3 with proteinuria. Methods Adriamycininduced nephrotic rat models were established by a single injection of adriamycin via the tail vein. Glomeruli and cortex tubuli of rats were dissected by laser microdissection. Real time quantitative RT-PCR was used to study the expression of ANGPTL3mRNA in kidney of ADR rate at 7, 14, 21 and 28 days successively following adriamycin injection. Results (1) In ADR rats, urinary protein and the level of triglyceride and cholesterol in serum increased significantly at day 14 (P
