Objective To investigate the application validity of the adjusted norm of WAIS-RC in the identification of intellectual disability.Methods128 patients with mental retardation (MR) were chosen for identification of the intellectual disability, measured their full scale IQs (FIQ) according to the original norm, calculated their four-subtest short forms FIQ respectively by Tellegen way according to the original standard norm and the new adjusted norm, then compared and analyzed the outcomes.ResultsThe short forms FIQ according to the original and the new norm had high correlation to full forms FIQ (P<0.01). The average of the short forms FIQ was higher than full forms FIQ according to the original norm (P<0.01), showing no significant difference according to the new norm(P＞0.05). In severe intelligence defected group according to full forms IQ, the grade classification corresponding rate of short forms FIQ according to the new norm was 0.00%, as well as the original norm. That in medium and mild intelligence defected groups was higher than that of original norm(P＜0.01).ConclusionThe test validity of adjusted norm short forms of WAIS-RC is superior to the original norm, but not suitable for severe intelligence defected.

OBJECTIVE: To investigate the expression of neuronal nitric oxide synthase (nNOS) in spinal dorsal horn and the effect of intrathecal katemine on the expression of nNOS in the rats with formalin-induced pain. METHODS: Thirty-two Sprague-Dawley rats were randomly divided into 4 groups (n=8 in each group): a control group (C), an intrathecal saline group (NS), a katemine 50 microg group (K1), and a katemine 100 microg group (K2). The rats that were anesthetized with 10% chlroral hydrate 300 - 350 mg/kg by abdominal injection were intrathecally inserted a microspinal catheter into the lumbar region according to the method of modified Yaksh. After 5 days ,the rats in Group NS, K1 and K2 were intrathecal 20 microL saline or 10 microL katemine (50, 100 microg) followed by 10 microL saline, respectively. Thirty minutes later, 5% formalin 50 microL was subcutaneously injected into the left hindpaw. Pain intensity scoring (PIS) was used to assess antinociceptive behavior within 1 h after the formalin injection. The expression of nNOS in the spinal dorsal horn of L5 segment was assayed using immunohistochemistry 24 h later. RESULTS: Compared with Group NS, PIS of Group K1 and K2 was decreased obviously (P<0.01) in the second phase of formalin pain. The number of immunoreactive soma and immunohistochemistic dying grade of nNOS in the spinal dorsal horn of L5 segment was higher in Group NS than that in Group C (P<0.01), but Group K1 and K2 were lower than Group NS (P<0.01). CONCLUSION There was significant antinociception of intrathecal katemine in rats with formalin pain. Intrathecal katemine significantly inhibited the increase of nNOS expression in the spinal dorsal horn of formalin-induced pain, suggesting nNOS plays an important role in nociceptive transmission and modulation of the spinal cord.

OBJECTIVE: To investigate the effects of intravenous anesthetics on LPS-induced inflammatory responses of primary cultures of rat glial cells in vitro. METHODS: The primary cultures of rat glial cells were stimulated with lipopolysaccharide( LPS) to produce inflammatory responses. Glial cells were divided into 8 groups (n=4): blank control (Group C), LPS(Group L), 100micromol/L ketamine with LPS(Group K1), 1000micromol/L ketamine with LPS (Group K2), 30micromol/L propofol with LPS (Group P1), 300micromol/L propofol with LPS (Group P2), 3micromol/L midazolane with LPS (Group M1), and 30micromol/L midazolane with LPS (Group M2). TNF-alpha released into the culture media was measured by radioimmunity assay. RESULTS: Compared with the blank control Group C, LPS-induced TNF-alpha productions in Group L, K1, K2, P1, P2, M1 and M2 increased significantly. The levels of TNF-alpha in Group K1 and K2 were significantly lower than those in Group L (P<0.05), but TNF-alpha productions in Group P1, P2, M1 and M2 were not significantly different as compared with that in Group L. CONCLUSION Ketamine can reduce LPS-induced TNF-alpha production of glial cells, thereby inhabiting some of the inflammatory responses. Propofol and midazolam have no effect on the production of TNF-alpha from LPS-stimulated glial cells.

OBJECTIVETo evaluate the efficacy and safety of wuling Capsule combined with Pinaverium Bromide in treatment of irritable bowel syndrome (IBS).

METHODSSixty-four IBS patients were randomized into two groups, the treatment group and the control group, 32 in each group. Patients in the treatment group took wuling Capsule (0. 33 g/capsule, 3 times per day) and Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day) , while those in the control group only took Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day). The therapeutic course for all was 6 weeks. IBS symptom score questionnaire, IBS-Quality of Life (IBS-QOL) , Self-Rating Depression Scale (SDS) , and Self-Rating Anxiety Scale (SAS) were assessed before and after treatment. Adverse reactions were also observed.

RESULTSThe improvement of abdominal pain, stool frequency, and stool properties, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of dysphoria, body image, concerns for health, and dietary restriction of IBS-QOL, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of SDS and SAS, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). No severe adverse reaction occurred in either group.

CONCLUSIONCombination therapy of wuling Capsule and Pinaverium Bromide could improve abdominal pain and defecation, attenuate depression and anxiety of IBS patients with higher safety.

To develop a Huntington’s disease(HD) cell model in vitro to screen drugs targeting the aggregation of polyQ,different length of CAG repeat fragments were amplified by random primer PCR, identified by DNA sequencing and were fused to the N-terminus of CAT in the pCAR system respectively which had been constructed and identified before. Recombinant plasmids were transformed into and induced to express in the host E.coli. SDS-PAGE and chloramphenicol resistance test were done to determine the solubility of the polyQ and chloramphenicol resistance levels of the fusions. With different length of CAG repeat fragments cloned and expressed in the CAT-fusion protein reporting system, it is found that when the length of the fragments increased over 40, their encoding polyQ expressed as insoluble protein and chloramphenicol resistance levels are lower, while under 40, the polyQ expressed as soluble ones and chloramphenicol resistance levels are higher. A in vitro HD model that could minimize the pathological process of the HD thus has been developed. With which by measure the recombinant bacteria’s resistance to chloramphenicol, the polyQ’ solubility and folding state in vitro by quality and quantity could be determined. Thus this model can be used to screen drugs or bioactivity materials that can inhibit aggregation of the polyQ, which thereby shedding new light on the prevent, diagnosis and therapy of HD.

OBJECTIVE: To explore the clinical efficacy of intrathecally administered low dose sufentanil-bupivacaine in transurethral resection of the prostate (TURP). METHODS. Ninety patient (ASA I - III) undergoing TURP were randomly divided into 3 groups (n = 30); Group A, B and C. Group A received 7.5 mg bupivacaine + 5 microg sufentanil + 10% glucose; Group B received 7.5 mg bupivacaine + 7.5 microg sufentanil + 10% glucose; Group C received 15 mg bupivacaine + 10% glucose. The volume was 3 mL in every group. SP, DP, HR, SpO2, the degree of motor and sensory blockade and the side effect were observed. RESULTS: SP/DP was significantly decreased in Group C than that in Group and Group B (p<0.05), HR and SpO2 in group B were decreased to different degrees 15 min after the injection (p<0.05). The complete recovery time of motor nerve blockade and the regression time of sensory blockade were obviously prolonged in Group C (p<0.05). There were no significant differences in analgesic effect among the three groups during the operation, but the incidence of pruritus was higher in both group A and Group B than that in Group C during the first 24 hours after the injection. CONCLUSION Spinal anesthesia with low dose sufentanil-bupivacaine possesses relatively steady hemodynamics. The blockade degree of motor and sensory blockade in this spinal anesthesia is lower than that in standard spinal bupivacaine in TURP.

OBJECTIVE: To evaluate the effect of intrathecal pumping tramadol on cell-mediated immunity in rats with formalin inflammatory pain. METHODS: Thirty-two Sprague-Dawley adult male rats weighting 250 approximately 300 g were randomly divided into 4 groups (n=8 in each group):Saline group (NS) and 3 tramadol groups (T1,T2,and T3). The rats were anesthetized with intraperitoneal chloral hydrate (300 approximately 350)mg/kg. Microspinal catheter was inserted into the subarachnoid space at the lumber region according to modified Yaksh techniques. In the tramadol groups,after 5 days tramadol was continuously infused through the spinal catheter at 50 (T1),25 (T2), and 12.5 microg/h (T3) for 7 days. In the NS group normal saline was continuously infused instead of tramadol. On Day 7 formalin (5%, 50 microL) was injected into the plantar surface of the left hindpaw. The number of flinches, lickings and total time of licking was recorded for 60 min.Pain intensity scoring(PIS)(0 approximately 3;0= no pain, 3=severe pain) was used to assess the antinociceptive effect of intrathecal tramadol. The rats were killed after the evaluation of pain intensity. Body weight and spleen weight were measured and spleen index (spleen weight/body weight) was calculated. T-lymphocyte function was evaluated based on Concanavalin-A(ConA) induced splenocyte proliferation. A modified lactic acid dehydrogenase(LDH) release assay was done to assess the NK cell activity. Phenotypic expressions of cell surface markers of T lymphocyte subsets (CD3+, CD3+ CD4+, CD3+ CD8+, and CD4+/ CD8+) and NK cell(CD161+) in the spleen were analyzed by flow cytometry. RESULTS: The PIS scores were significantly lower in the T1,T2,and T3 groups than those in the NS group. The spleen index and splenocyte proliferation induced by ConA were significantly suppressed in the T1 group,and the phenotypes of T lymphocyte subsets were significantly changed,but no significant difference was found in the T2 and T3 groups compared with the NS group. There were no differences in NK cell activity in the 3 tramadol groups from the control group. CONCLUSION Intrathecal pumping tramadol has significantly antinociceptive effect. Intrathecal pumping higher dosage tramadol (50microg/h) suppresses T lymphocyte proliferation and alteres T lymphocyte subset phenotype but does not affect NK cell activity. General analgesic dosage tramadol (25 and 12.5 microg/h) has no effect on the immune function.
