Trichinella spiralis infection in rodents is a well-known model of intestinal inflammation associated with hypermotility. The aim of the study was to use this experimental model to elucidate if Th17 cells are involved in the development of gastrointestinal hypermotility. Colonic smooth muscle contractility was investigated in response to acetylcholine. The levels of IL-17, IL-23 and TGF-beta1 in colon were measured by Western blotting. Flow cytometric detection of intracellular IFN-gamma/IL-4/IL-17 cytokine production was used to analyze the proportions of CD4+ T cells subsets in colon. Our results showed that colonic muscle contractility was increased 2 weeks post infection (PI) and stayed high 12 weeks PI when no discernible inflammation was present in the gut. The proportion of Th17 cells and the expression of IL-17 were up-regulated in colon 2 weeks PI and returned to normal 8 weeks PI. The content of IL-17 was correlated with the colonic smooth muscle hypercontracility 2 weeks PI. Meanwhile, TGF-beta1 was increased 2 weeks PI, while IL-23 was normal. Our results suggest that Th17 cells affect the colonic muscle contractility in mice infected with Trichinella spiralis at intestine stage but not at muscle stage and the effect of Th17 cells on muscle contractility might be induced by TGF-beta1. Other cytokines might be involved in the hypercontracility of colonic smooth muscle at muscle stage.

The benefit achieved by concurrent chemoradiotherapy (CCR) and sequential chemoradiotherapy (SCR) vs radiotherapy (RT) alone for patients with stage II-IVa nasopharyngeal carcinoma (NPC) was compared. A total of 113 patients with stage II-IV a NPC were allotted into CCR group (n=38), SCR group (n=36) and RT alone group (n=39). All patients were irradiated with the same RT technique to ≥66 Gy at 2 Gy per fraction, conventional 5 fractions/week in all groups. The CCR group received concurrent chemotherapy of weekly cisplatin for 7 weeks, and the SCR group received neoadjuvant and (or) adjuvant chemotherapy. The results showed that the 3- and 5-year overall survival rate was significantly higher in CCR group than in RT alone group (92.16% vs 61.54%, 81.58% vs 51.28%, P<0.005). The median survival time was significantly longer in CCR group than in RT alone group (67.8 months vs 52.7 months, P<0.005). It was concluded that CCR could significantly improve overall survival rate, progression-free survival rate, and median survival time when compared with RT alone.

BACKGROUND:Maxil ofacial malformation limits the function of the mandible, produces the overload of the temporalmandibular joint leading to oral diseases. OBJECTIVE:To measure the characteristics of mandibular movement in populations with various types of dental occlusion. METHODS:Thirty-three volunteers (1 male and 32 females, mean age 21.71 years) meeting the inclusion criteria were enrol ed from Dalian Medical University, China and divided into four groups:normal control (n=10), Angle’s class I, II, III malocclusion (n=10, 8, 5). The protrusion, lateral, opening motion trace of mandibular central incisor and the right mandibular first molar, and the trace from mandibular postural position to intercuspal position were measured using the mandibular kinesiograph. The features of different occlusal patterns were analyzed using SPSS 17.0 software. RESULTS AND CONCLUSION:In the trace of protrusion, lateral, opening and closing motion, there were significant differences in the trace of the right mandibular first molar’s Max.Slant between Angle’s class II malocclusion group and the other three groups (P<0.05). In the trace of open wide and close fast, there were significant differences in the trace of mandibular central incisor in vertical distances between normal control group and Angle’s class I, III malocclusion groups (P<0.05);there were significant differences in the trace of mandibular central incisor in Max.Slant between normal control group and Angle’s class I malocclusion group (P<0.05);there were significant differences in the trace of the right mandibular first molar in vertical distances between Angle’s class II malocclusion group and the other three groups (P<0.05);there were significant differences in the trace of the right mandibular first molar in Max.Opening velocity between normal control group and Angle’s class II, III malocclusion groups (P<0.05). There were no significant differences in free space between the four groups (P>0.05). These results indicate that there are differences in the trace of mandibular central incisor and the trace of the right mandibular first molar in range and speed between different occlusal patterns. We can draw a conclusion that malocclusion has effects on the direction, range and speed of mandibular movement.

OBJECTIVETo evaluate the toxicity and efficacy of primary liver cancer (PLC) treated by hypofractionated three-dimensional conformal radiotherapy (3DCRT) and investigate the prognostic factors.
METHODSBetween April 1999 and August 2003, 128 PLC patients received hypofractionated 3DCRT. According to UICC/AJCC staging system, there were 83 T3 patients, 45 T4, with none of them having lymph node metastasis. The mean value of gross tumor volume (GTV) was (458.92 +/- 429.8) cm(3) (6.2-2097 cm(3)). Thirty-four patients had portal vein tumor thrombosis (PVTT). 108 patients had Child-Pugh Grade A liver cirrhosis and 20 Child-Pugh Grade B liver cirrhosis. All patients received a total dose of (53.6 +/- 6.6) Gy/4-8 Gy per fraction/3 fractions per week. Forty-eight of these patients received 3DCRT combined with transarterial chemoembolization (TACE).
RESULTSSeven patients died within 3 months after the treatment were dismissed from the series. The response rate (CR + PR) was 55% (67/121). The overall 1-, 2-, and 3-year survival rate was 65.0%, 43.3%, and 33.1%, respectively. T stage (P = 0.001), GTV (P = 0.0001), PVTT (P = 0.0001) and Child-Pugh Grade (P = 0.0001) had significant impact on the overall survival. However, only GTV and Child-Pugh Grade were independent significant prognostic factors by Cox-regression analysis, (P = 0.044 and P = 0.015).
CONCLUSIONT stage, GTV, PVTT and Child-Pugh Grade have significant impact on the overall survival in primary liver cancer patients treated by three-dimensional conformal radiotherapy. But only GTV and Child-Pugh Grade are independent prognostic factors.

OBJECTIVETo observe the change of sexual function in male kidney transplant recipients.
METHODSSixty married males, aged 26 to 45 years, who had received kidney transplantations at least half a year before and whose serum creatinine (Scr) was under 200 mumol/L, were selected randomly in the study. Sexual functions were reviewed before and after the patients' renal failure and after kidney transplantations. The results were analyzed in Chi-Square test methods.
RESULTSTheir sexual functions, significantly aggravated after renal failure, were improved after kidney transplantations, but failed to return to normal. The recipients had a common worry that their sex lives might affect the renal grafts.
CONCLUSIONSKidney transplantations significantly improve the sexual functions of these renal failure patients. It is quite necessary to provide sexological guidance to kidney transplant recipients and their spouses.

OBJECTIVETo study the effects of environmental enrichment on neuron proliferation, learning and memory ability and motor ability in neonatal rats with hypoxic-ischemic brain damage (HIBD).
METHODSOne hundred and eight 7-day-old Sprague-Dawley rats were randomly divided into three groups: sham operation (CON group), HIBD and intervention group. HIBD model was prepared according to the classic Rice-Vannucci method. Environmental enrichment was administered for the rats in the intervention group after HIBD inducement. Behavioral tests (Water maze test, Suspension test and Slope test) were performed and the number of neural cells in the left hippocampus was examined 7, 14 and 28 days after intervention.
RESULTSThe pyramid cells in the hippocampus CA1 area in the HIBD group were significantly less than in the CON group at 7, 14 and 28 days (P<0.05). The number of pyramid cells in the hippocampus CA1 area in the intervention group was significantly higher than in the HIBD group (P<0.01) at 7, 14 and 28 days. The hidden platform escape latency period (EL) in the Water maze test was significantly more prolonged and the cross-platform number within 2 minutes was significantly less in the HIBD and the intervention groups than in the CON group at all observed time points (P<0.01). The EL was significantly shorter and the cross-platform number within 2 minutes was significantly higher in the intervention group than in the HIBD group at all observed time points (P<0.01). The maintain time and score in the Suspension test were significantly lower and the time in the Slope test was significantly more prolonged in the HIBD and intervention groups than in the CON group at 7, 14 and 28 days (P<0.01). An increased maintain time and score and a decreased time in the Slope test were found in the intervention group compared with the HIBD group at 14 and 28 days (P<0.01).
CONCLUSIONSEnvironmental enrichment can improve motor function, learning and memory ability, and promote the repair and proliferation of neurons in neonatal rats with HIBD.
