BACKGROUND:Neural stem cels can repair the damaged brain tissues with potentials of proliferation and differentiation, which become one of the important directions for treating cerebral palsy. OBJECTIVE:To observe the clinical effect and safety of neural stem cel transplantation on the treatment of cerebral palsy in children. METHODS:Neural stem cels were isolated from human embryonic brain and identified by immunofluorescence staining, which were transplanted intravenously into 26 children with cerebral palsy. Children's motor functions were evaluated by gross motor function measure scale and Peabody development motor scale-fine motor scale before treatment, and 3 and 6 months after treatment. Routine blood test and liver-kidney function were detected before and after treatment. Clinical adverse reactions in children with cerebral palsy were monitored. RESULTS AND CONCLUSION:The lost cases were not found during 6 months of folow-up. Specific proteins of neural stem cels were al positive in this study. At 3 and 6 months after transplantation, the A, B, C functional area scores and total score on the gross motor function measure scale were obviously increased (P < 0.05,P < 0.01), but the C and D functional area scores were not remarkably elevated (P > 0.05). At 3 months after transplantation, the fine motor quotient, grasping subtest and visual-motor integration were not remarkably increased (P > 0.05); these scores, however, were elevated after 6 months with statistical significance (P < 0.05, P < 0.01). The results of routine blood test and liver-kidney function in 26 children were in normal range, and there were no serious adverse reactions during the cel transplantation. Therefore, neural stem cel transplantation has high safety and good curative effects to improve the motor function of children with severe cerebral palsy, especialy for gross motors.

Objective To evaluate the clinical value of multiplex ligation-dependent probe amplification (MLPA) technique used in karyotype analysis of chorionic villi from missed abortion. Methods Feb 2008 to Oct 2008, 91 patients with missed abortion diagnosed by hormonal measurement, type B ultrasound and physical exam matched with 20 normal pregnant women undergoing artificial abortion were enrolled in this study. Chorionic villi was obtained by suction dilation and curettage in aseptic condition, then those villi was cultured and analyzed by traditional cytogenetic karyotyping method, in the mean time, the DNA extracted from villi was detected by MLPA. The results of chromosomal G-banding of chorionic villi were compared between two methods. Results The diagnostic concordance of MLPA and traditional karyotyping was observed in 92% (84/91) cases, there were 84 cases in the case group with diagnostic concordance by traditional karyotyping and MLPA except 7 cases of euploidy could not be detected by MLPA. The 84 cases included 40 normal karyotype,29 trisomy of euchromosome, 1 double trisomy of euchromosome, 10 monosomy X , 1 monosomy X combined with trisomy of euchromosome, 2 chimaera of X chromosome, 1 structural abnormity of euchromosome. Among 7 cases with discordance diagnosis, 2 cases with trisomy and 5 cases with tetrasomy of euchromosome were identified in traditional karyotyping, however, they were all diagnosed with normal disomy by MLPA. Of 20 villi from normal pregnancy, two methods got the consistent results. Conclusion The MLPA was rapid and efficacy method used for analyzing aneuploids in chorionic villi.

OBJECTIVETo investigate the risk factors of surgical site infection (SSI) in definitive surgery of intestinal fistulas.

METHODSPatients with gastrointestinal fistula undergoing definitive operation during November 2011 to November 2013 in Jinling Hospital were prospectively enrolled in the study. Risk factors of SSI were analyzed. Patients' characteristics, surgery-related data and fistula-related data were prospectively collected. Risk factors of SSI were analyzed.

RESULTSA total of 191 cases were enrolled and 51 cases developed SSI. Univariate analysis showed that patients with risk index category (RIC)≥2, length of abdominal incisions>15 cm, and duration of drainage tubes>10 days had significantly higher incidence of SSI (P<0.05). Multivariate Logistics analysis demonstrated that RIC and duration of drainage tube were independent risk factors for SSI (P=0.02, P=0.01, respectively).

CONCLUSIONSRIC≥2 and duration of drainage tubes>10 days are independent risk factors for development of SSI.

OBJECTIVETo compare the differences of radiographical and functional outcomes between traditional and minimally invasive approach in treating Hawskins type I fractures of the talar neck.

METHODSFrom February 2000 to February 2008, 37 patients underwent reduction and internal fixation using two different approaches. In minimally invasive approach group, there were 16 males and 2 females, ranging in age from 20 to 47 years, averaged (35.2 +/- 3.1) years, and in traditional approach group, there were 15 males and 4 females, ranging in age from 22 to 44 years, averaged (35.3 +/- 2.3)years. All the patients had Hawskins type I fractures. The following data were compared between two groups: operation time, blood loss, length of incision and function of ankle joint. All the patients were graded by Hawkins points-scoring system after operation.

RESULTSAll patients were followed up. The duration ranged from 2 to 10 years, with an average of 5.6 years. The index such as operation time, blood loss and the length of incision of patients in minimally invasive approach group were significantly less than those of patients in traditional approach group. According to AOFAS points-scoring system, the score of minimally invasive group was higher than that of traditional approach group.

CONCLUSIONCompared with traditional approach, minimally invasive approach can protect blood supply better, get better clinical effects,which is worth of choosing to treat Hawskins type II fractures of talar neck.

OBJECTIVEThere is growing evidence indicating that reactions of inflammatory system play an important role in stroke and development of carotid plaques. It is purposed to understand the relationship between serum level of c-reactive protein (CPR) and size of cerebral infarction, carotid plaques and prognosis of ischemic stroke.

METHODSA total of 121 patients with ischemic stroke were included in the study. Serum level of CRP was measured within 72 hours after onset of index stroke. All patients were scored by CNDF based on deficit in their clinical neurological function, and examined with CT/MRI and carotid duplex ultrasound scanning.

RESULTSLeukocyte count and blood glucose level at admission were significantly higher in the group with abnormal serum level of CRP than those with normal one (P = 0.045 and P = 0.021, respectively). Incidence of territory infarction (42 cases, 61.76%) was also significantly higher than that of lacunar infarction (23 cases, 43.4%), with P = 0.044. Occurrence of carotid plaques was higher in the former (32 cases, 65.30%) than that in the latter (17 cases, 34.69%), with P = 0.035. CNFD scores were higher in the former (ranging 6 - 35, with a median of 18) than those in the latter (ranging 6 - 28, with a median of 11), with Mann-Whitney U test, P = 0.0001. And, more severe prognosis was also found in the former than in the latter, with P = 0.0001.

CONCLUSIONSerum level of CRP was an important prognostic marker for carotid plaque and stroke.

OBJECTIVETo investigate the anatomic characteristics of splenic flexure, surgical techniques, and oncologic outcomes in 52 patients with non-obstructive splenic flexure colon cancer.

METHODSClinical data of 52 patients with non-obstructive splenic flexure colon cancer from March 2004 to March 2011 in the Department of General Surgery at the Henan Province Tumor Hospital were analyzed retrospectively.

RESULTSThere were 37 patients of regular type, 5 of mobile type, and 10 of adhesive type. All the patients received radical operation. Eighteen patients received pre-small intestine anastomosis, including 12 cases with regular type, 4 with mobile type, and 2 with adhesive type. The difference in pre-small intestine anastomosis among the three types was not statistically significant(P=0.062). In addition, 32 cases received retro-ileum anastomosis. There were no significant differences in operative time, intraoperative blood loss, number of lymph node dissection and positive lymph node, and postoperation complication rate among the three types. Follow up was available in all the cases. Five-year survival rates of cases with regular type, mobile type and adhesive type were 62.5%, 59.2% and 58.7% respectively(P>0.05).

CONCLUSIONSRadical resection can provide satisfactory survival for splenic flexure colon cancer patients. The anatomy of splenic flexure does not affect the type of anastomosis. Retro-ileum anastomosis is a simple and effective method for reconstruction after radical resection of the tumor.

OBJECTIVEChinese jianpi herbal recipe Weichangan (WCA) could increase the survival rate of advanced gastric cancer. This study was designed to investigate the molecular mechanism of WCA in treatment of gastric cancer by cDNA array, real-time quantitative PCR and immunohistochemical technique.

METHODA human gastric adenocarcinoma cell line SGC-7901 grafted onto nude mouse was used as the animal model. The mice were divided into 3 groups, one control and the two representing experimental conditions. Animals in the two experimental groups received either WCA over a 34-day period or 5-fluorouracil (5-FU) over 6-day period starting at 8th day after grafting. Control animals received saline on an identical schedule. Animals were killed 41 days after being grafted. To assess the effect of therapy tumor weight was determined by a electron balance immediately after the animals killed. SP immunohistochemical method was used to detect the expression of proliferating cell nuclear antigen (PCNA) in xenografts. For detection of apoptotic cells, apoptotic indices (AI) were examined by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate fluorescence nick end labeling (TUNEL) method. SP method was also used to detect the expression of cleaved Caspase-3. The expression profiles in paired WCA treated gastric cancer samples and the N. S. control samples were studied by using a cDNA array representing 14, 181 cDNA clusters. The alterations in gene expression levels were confirmed by real-time quantitative PCR. SP method was used to detect the expression of Phospho-Stat3 (Tyr705) and bcl-2.

RESULTWhen compared with controls, tumor growth was significantly inhibited by treatment with the WCA or 5-FU (P < 0.01, respectively). The average of tumor inhibitory rate in WCA group was (44.32 +/- 5.67)% and 5-FU (47.04 +/- 11.33)%. The average labeling index (LI) for PCNA in WCA group and 5-FU group was significantly decreased compared with the control group respectively. AI of human gastric cancer xenografts in nude mice was significantly increased to (9.72 +/- 4.51)% using TUNEL method in WCA group compared with the controls (2.45 +/- 1.37)%. 5-FU group was also found a significantly increased AI compared with the controls. The expression of cleaved Caspase-3 in WCA group and 5-FU group was significantly increased compared with the control group respectively. There were 45 different expression ESTs among the control sample pool and WCA sample pool. There were 24 ESTs up-regulated in WCA samples and 21 ESTs down-regulated. These 45 ESTs contains 35 cloned genes and 11 unknown ESTs. By using Real-time Quantitative PCR, the expression level of Stat3 (2(-deltadeltaCT) = 0.16) , RIPX (2(-deltadeltaCT) = 0.18), ROD1 (2(-deltadeltaCT) = 0.23) and bcl-2 (2 (-deltadeltaCT) = 0.10) was lower in WCA group than that in control group respectively. The expression of Phospho-Stat3 (Tyr705) and bcl-2 in WCA group and 5-FU group was significantly decreased compared with the control group respectively.

CONCLUSIONChinese jianpi herbal recipe WCA could inhibit gastric cancer cell SGC-7901 growth in vivo. WCA could induce gastric cancer cell apoptosis and suppress proliferation. Its mechanisms might be involved in the down-regulation of Stat3, RIPX, ROD1 and bcl-2 gene.

Bamboo salt, a Korean folk medicine, is prepared with solar salt (sea salt) and baked several times at high temperatures in a bamboo case. In this study, we compared the preventive effects of bamboo salt and purified and solar salts on hepatic damage induced by carbon tetrachloride in Sprague-Dawley rats. Compared with purified and solar salts, bamboo salts prevented hepatic damage in rats, as evidenced by significantly reduced serum levels of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase (P < 0.05). Bamboo salt (baked 9x) triggered the greatest reduction in these enzyme levels. In addition, it also reduced the levels of the proinflammatory cytokines interleukin (IL)-6, interferon (IFN)-gamma, and tumor necrosis factor (TNF)-alpha. Histopathological sections of liver tissue demonstrated the protective effect of bamboo salt, whereas sections from animals treated with the other salt groups showed a greater degree of necrosis. We also performed reverse transcription-polymerase chain reaction and western blot analyses of the inflammation-related genes iNOS, COX-2, TNF-alpha, and IL-1beta in rat liver tissues. Bamboo salt induced a significant decrease (~80%) in mRNA and protein expression levels of COX-2, iNOS, TNF-alpha, and IL-1beta, compared with the other salts. Thus, we found that baked bamboo salt preparations could prevent CCl4-induced hepatic damage in vivo.
