Objective To study the effect of hand intrinsic muscle exercise on postoperative recovery of fine movement in children with hand injury.Methods From January 2009 to December 2011,64 children with hand injury were randomly divided to exercise group and control group equally.Hand intrinsic muscle exercise and rehabilitative care were conducted in the exercise group while traditional rehabilitative therapies in control group.After 3-month therapy,MMDT(Minnesota Manual Dexterity Test)and PPT(Purdue Pegboard Test)were conducted to evaluate the functional recovery of hands.Result The results of MMDT and PPT were obviously better in the exercise group than in the control group(P<0.01).Conclusion Hand intrinsic muscle exercise may be effectively in promoting the recovery of fine movement in children with hand injury.

Objective To investigate the allelic polymorphism of Human Leukocyte Antigen(HLA)-DRB1*04 in Southern and Northern Chinese Han populations.Method A total of 104 and 168 samples of HLA-DRB1*04 alleles from Southern and Northern Chinese Han populations respectively were genotyped at high-resolution by PCR-SBT,and then the DRB1*0406/0449 ambiguous allele pairs were identified via high-resolution PCR-SSP.The allelic distribution of DRB1*04 in Southern and Northern Chinese Han populations were compared with other different populations by chi-square test.Results All 56 ambiguous allelic pairs of DRB1*0406/0449 were identified as DRB1*0406.A total of 5 alleles were observed in Southern Chinese Han population and the most frequent alleles were DRB1*0405(47.32%),DRB1*0406(24.24%)and DRB1*0403(16.35%).There were 10 alleles tested in Northern Chinese Han population,and the major alleles were DRB1*0405(40.48%),DRB1*0406(18.45%) and DRB1*0403(17.26%).The overall distribution of DRB1*04 alleles in Southern and Northern Chinese Han differed significantly from that of the Caucasian,African American,Hispanics,and Asian and Pacific Islanders,but not from the Korean.Conclusions The overall distribution of HLA-DRB1*04 alleles differed significantly between Southern and Northern Chinese Han populations,but the major alleles DRB1*0405,DRB1*0406 and DRB1*0403 showed the same distribute characteristic.The distribution of DRB1*04 alleles in different populations has their own characteristics.

Objective To investigate the effects of rhGH on hypoalbuminemia in cirrhotic rats after partial hepatectomy. Methods Thirty rats were randomly divided into normal control group ( n =6), liver cirrhosis group (LC group, n =6), liver cirrhosis and hepatectomy group (LCH group, n =6), PN (parenteral nutrition) group ( n =6, given PN after hepatectomy) and rhGH+PN group ( n =6,given rhGH and PN after hepatectomy). Liver function and blood glucose were measured. The expression of ALB mRNA was detected by RT PCR. Liver Ki67 immunohistochemistry was studied. Results Compared with PN group, serum ALP was lower; serum ALB and blood glucose were higher in rhGH+PN group. The expression of hepatic ALB mRNA was higher, and hepatic Ki67 labeling index was higher as well in this group. Conclusion rhGH can improve hypoalbuminemia after partial hepatectomy in cirrhotic rats with partial hepatectomy.

Objective To evaluate the effects of branched-chain amino acids-enriched early parenteral and enteral nutrition on the liver function and serum aminograms in cirrhotic rats after partial hepatectomy. Methods In this prospective randomized controlled study, 24 cirrhotic rats, induced by thioacetamide, were randomized into three groups: enteral nutrition (EN) group, EN + branched-chain amino acid (BCAA) group, and parenteral nutrition (PN) + BCAA group. After receiving partial hepatectomy, rats in all three groups were nutritionally supported with equal amount of calorie and nitrogen contents from the 1st postoperative day ( PO day 1 ) to PO day 5. On PO day 6, parameters including body weight, liver functions, prealbumin, transferring, and serum aminograms were measured or determined, and the level of liver albumin mRNA was detected by reversal transcription-polymerase chain reaction and morphological examinations such as HE staining and immunohistochemical staining, which were assessed by index of Ki67 protein index. Results Body weight was significantly decreased in all three groups on PO day 6 (P ＜0.05 ). Compared with EN + BCAA group, serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase after partial hepatectomy were significantly higher in PN + BCAA group (P ＜0.05 ). Serum alkaline phosphatase level was significantly higher in PN + BCAA group than in EN group ( P ＜0. 05). The level of prealbumin was significantly lower in PN + BCAA group when compared with EN group or EN +BCAA group ( both P ＜ 0. 05 ), although no such significant difference was noted in terms of transferrin ( P ＞0. 05 ). The levels of leucine and isoleucine elevated while those of tyrosine, phenylalanine, arginine and tryptophan declined in PN + BCAA group or EN + BCAA group when compared with EN group ( P ＜ 0. 05 ). Aminograms were not significantly different between EN + BCAA group and PN + BCAA group ( P ＞ 0. 05 ). Levels of total amino acid and aromatic amino acid (AAA) were significantly lower while BCAA and ratio between BCAA and AAA (BCAA/AAA) were significantly higher in PN + BCAA group or EN + BCAA group than in EN group (P ＜ 0. 05 ).Significantly lower level of albumin mRNA and index of Ki67 were observed in PN + BCAA group than in EN group or EN + BCAA group (P ＜ 0.05 ) on PO day 6. Conclusions BCAA-enriched EN or PN reverses amino acid disequilibrium and restores BCAA/AAA in cirrhotic rats after partial hepatectomy. Compared with PN, EN is superior in improving postoperative liver function, promoting protein synthesis, and speed up tissue regeneration in the postoperative liver. However, it still can not restore serum albumin in a short term.

Objective To determine the safety and efficacy of minimally invasive surgical treatment for post-traumatic thoracolumbar kyphosis. Methods A retrospective review was performed on seven patients with post-traumatic thoracolumbar kyphosis admitted from April 2009 to February 2010.There were four males and three females, at average age of 45.3 years. After general anesthesia, minimally invasive transarticular osteotomy and multi-level SextantTM percutaneous reduction and internal fixation were performed under QuadrantTM working tube system. The status of pain and ability was evaluated by using visual analogue scale (VAS) and Oswestry disability index (ODI). The kyphotic deformity was evaluated by using the Cobb's angle. Results The operation lasted for mean 135 minutes, with mean perioperative blood loss of 106 ml but with no any complications occurred. The mean follow -up period was 5.5 months ( range 4 -16 months ). The mean VAS score was improved from preoperative ( 7.6 ±3.5) points to postoperative (2.5 ± 1.3) points, with statistical difference (P ＜0.01 ). The mean ODI was improved from preoperative 53.6 ± 24.2 to postoperative 20.6 ± 6.3, with statistical difference ( P ＜0.01 ). The Cobb angle was also improved from preoperative ( 32. 1 ± 4.5 ) ° to postoperative ( 7.3 ±2.9 ) °, with statistical difference ( P ＜ 0. 01 ). Conclusion Minimally invasive transarticular osteotomy under QuadrantTM working tube system is a safe and effective alternative for dealing with post-traumatic thoracolumbar kyphosis.

Background and purpose: In recent years indirubin-3'-monoxime has been found to be capable of inhibiting some cell proliferation in vitro and in vivo studies, but human colon cancer HT-29 cells, therefore the purpose in this paper was to study the effect of indirubin-3'-monoxime on proliferation and apoptosis of HT-29 cells and its associated mechanism. Methods: HT-29 cells were treated with indirubin-3'-monoxime. The proliferative status of cells was measured by methabenzthiazuron (MTT) assay, flow cytometry (FCM) was used to measure the apoptosis rate. RT-PCR was used to measure the transcription of apoptosis suppressor gene bcl-2, survivin and apoptosis promoting gene Bar. Results: Indimbin-3'-monoxime inhibited growth of HT-29 cells in a dose-dependent and time-dependent manner (F=11.25, P<0.01). The apoptosis rate increased after the treatment by indirubin-3'-monoxime at 10 μmol/L. There were significant differences between different time groups (F=195.25, P<0.01). The transcription of survivin (F=78.75, P<0.01) and Bax (F=87.61, P<0.01) mRNA in HT-29 cells were increased; the transcription of bcl-2 was significantly decreased (F=95.82, P<0.01). Conclusion: Indirubin-3'-monoxime has obviously inhibited proliferation and induce apoptosis of colon cancer HT-29 cells, its mechanism may be related to decrease the bcl-2/Bax ratio.

BACKGROUND: Continuous blood purification can remove cytokines and inflammatory mediators, maintain homeostasis and prevent the occurrence of multiple organ dysfunction syndrome in patients with severe pancreatitis, which has become the main therapy for severe pancreatitis. Since the hemodialysis technology began to be applied clinical y, the biological and physicochemical properties of hemodialysis membrane materials have been studied. A variety of hemodialysis membranes have been developed in order to improve the biocompatibility and anticoagulant effect in vitro. OBJECTIVE: To investigate the application effect of hemodialysis membranes on severe pancreatitis. METHODS: Ten Wistar rats were selected to make rat models of severe pancreatitis and then were randomized into two groups (n=5 per group): homophone membrane group and polysulfone membrane group. Hemodialysis- related biochemical parameters were detected in the two groups. RESULTS AND CONCLUSION: Compared with the homophone membrane, ultrafiltration coefficient, creatinine clearance, blood urea nitrogen clearance, phosphorus clearance, number of circulating endothelial cel s, and levels of plasma nitric oxide and asymmetric dimethylarginine were significantly lower in the polysulfone membrane group (P < 0.05). Vitamin B12 clearance and amount of pre-congestion increased significantly in the polysulfone membrane group as compared with the homophone membrane (P < 0.05). These findings indicate that the polysulfone membrane for hemodialysis has good biocompatibility, and keeps a stable environment in vivo for severe pancreatitis patients.
