Diabetic peripheral neuropathy (DPN), one of the most common chronic complications of diabetes, is characterized by allodynia, hyperalgesia and spontaneous pain. Chinese epidemiological studies have shown that at least 25% diabetic patients suffered from painful DPN, which compromises patients' daily functioning and becomes a major health care problem. Although the pathogenesis of painful DPN is not fully understood and current treatment options are very limited, research in the field has advanced our understanding on the mechanism of painful DPN in the past Decade of Pain Research and Control. This review will mainly focus on evaluation of current diabetic animal models, possible molecular pathways and available therapies, with an emphasis on roles of purinergic receptor and its signaling transduction pathways. Common therapies address one or two DPN symptoms, while others offer wider symptom control, presumably by targeting pathophysiological mechanisms of DPN. Purinergic receptor signaling transduction pathways might become potential targets for treatment for painful DPN.

Objective　To investigate the prognostic influencing factors and recovery of CD4+ T lymphocytes in elderly HIV/AIDS patients after antiviral therapy by analyzing basic data and clinical follow-up data of elderly HIV/AIDS patients. Methods　The clinical data of 3 618 elderly AIDS patients aged ≥50 yeas who received antiretroviral therapy (ART) at HIV ART sites in Liuzhou City from 2005-2015 were collected. The data, including basic information, CD4+ T cell count, WHO clinical stage, infection route and follow-up, were retrospectively analyzed. Kaplan-Meier method was used to compare the differences in patient survival, multivariate Cox regression to analyze the independent influencing factors influencing the risk of death, and to compare the recovery of CD4+ T cell counts during follow-up of patients of different genders. Results　During the follow-up period, the 5-year cumulative survival rate up to the observation endpoint was 0.82 (female) and 0.66 (male). Multivariate logistic regression analysis showed that the risk factors affecting the effect of antiviral treatment were age (OR=1.909, 95%CI:1.474-2.464, P<0.001), body mass index (BMI) (OR=0.744, 95%CI: 0.574-0.965, P=0.026), opportunistic infections (OI) (OR=1.223, 95%CI:1.028-1.454, P=0.023), gender (OR=0.692, 95%CI:0.503-0.952, P=0.023) and baseline CD4+ T lymphocytes count (OR=0.563, 95%CI:0.429-0.739, P<0.001). Recovery of CD4+ T lymphocyte counts showed when baseline CD4+ T lymphocyte counts were less than 200 cells/mm3, older women with HIV/AIDS had higher CD4+ T lymphocytes than men at all times of ART treatment (P<0.05). Conclusions　Older women have a higher survival rate than older men after five years of antiviral therapy. Age, BMI, gender, OI and baseline CD4+T lymphocyte count may be important indicators that affect the survival of elderly HIV/AIDS patients. Older women showed better recovery of CD4+ T lymphocytes than older men during the 4-year follow-up period after ART.

Objective To appraise the bowel control and quality of life after transanal improvement of Soave one-stage pull-through operation for Hirschsprung′s disease(HD) in infants.Methods Twenty-five patients(aged from 2 months to 3 years old) with HD underwent improved endorectal pull-through procedure and postoperative follow-up for 5 months to 6 years(average 4.5 years) including the occurrence of operation related complications sush as bowel control,constipation or postoperative enterocolitis and quality of life.Results Twenty-one patients completed the study were with a mean follow-up.The assessment of anal continence was graded as normal(4 scores),good(3 scores),and fair(2 scores) according to the previous study of other investigators.Of the 21 patients,16 were graded as normal,whereas 4 were as good and 1 fair.One patient developed constipation and 2 patients had postoperative enterocolitis.Conclusion Modified Soave procedure for Hirschsprang′s disease can get a good bowel control outcome and quality of life.

Objective To investigate the effect of local injection of Botulinum toxin type A(BTXA) on spasticity and function of the affected upper limb in stroke patients.Methods A total of 32 stroke patients were re- cruited and randomly divided into two groups:a BTXA group and a control group.All the patients had spasticity of upper limb muscles,which scored grade 2 to 3 with the Modified Ashworth Scale(MAS) ,and decreased elbow joint range of motion.The 16 patients in the BTXA group received BTXA injection in the biceps brachii muscles and flexor muscles of forearm on 10～15 points,while those in the control group did not.All the patients in both groups were treated with rehabilitation training techniques.The MAS,Fugl-Meyer upper limb function assessment and Barthel In- dex were employed to evaluate the changes of muscle tone,upper limb function and activity of living (ADL)perform- ance of the patients before injection and at 1st,2nd,6th 12th weeks after injection.Results The therapeutic effect between the BTXA group anti control group was significantly different in terms of biceps muscle tone,the scores of Fugl-Meyer upper limb function assessment and Barthel Index.Compared with preinjection,muscle tone was de- creased significantly and ADL performance was improved after injection in BTXA group.The effects of BTXA lasted more than 12 weeks.Conclusion Intramuscular muhipoint injection of BTXA was useful in reducing muscle spas- ticity,and was helpful for increasing motor ability of the affected upper limb and ADL performance of the stroke pa- tients.

OBJECTIVETo detect the loss of heterozygosity (LOH) in esophageal squamous cell carcinoma and adjacent high-grade squamous dysplasia, and to evaluate possible tumor suppressor genes in the development and progression of invasive malignancy.

METHODSLOH was detected in normal esophageal mucosa, high grade squamous dysplasia and esophageal squamous cell carcinoma using microdissection and polymerase chain reaction technology. The changes of LOH at seven microsatellite markers and the relationship between LOH rate and clinicopathologic parameters were analyzed.

RESULTSIn high grade squamous dysplasia, LOH was detected at D13S802 (40%), D13S267 (32%), D13S221 (31%), D9S942 (30%), D17S520 (24%) and D9S171 (33%). However, D17S1798 LOH was not detected. In invasive squamous cell carcinoma, LOH was detected as follows: D13S267 (71%), D13S802 (58%), D17S520 (55%), D13S221 (45%), D9S942 (43%), D9S171 (33%) and D17S1798 (11%). The frequency of LOH in the seven microsatellite markers, the pathologic grade, clinical stage and occurrence of lymph node metastasis did not show any statistically significant correlation (P > 0.05).

CONCLUSIONSThe progression from normal squamous epithelium to high grade squamous dysplasia and subsequently to invasive squamous cell carcinoma of the esophagus was associated with accumulation of genetic errors. Possible tumor suppressor genes related to the development of esophageal squamous cell carcinoma may exist near D13S802 (13q12.12). Possible tumor suppressor genes near D13S267 (13q13.1), D17S1798 (17p13.3) and D17S520 (17p13.1) may be related to the progression of esophageal squamous cell carcinoma.

BACKGROUND/AIMS: Patients with long-standing diabetes often demonstrate intestinal dysfunction and abdominal pain. However, the pathophysiology of abdominal pain in diabetic patients remains elusive. The purpose of study was to determine roles of voltage-gated sodium channels in dorsal root ganglion (DRG) in colonic hypersensitivity of rats with diabetes. METHODS: Diabetic models were induced by a single intraperitoneal injection of streptozotocin (STZ; 65 mg/kg) in adult female rats, while the control rats received citrate buffer only. Behavioral responses to colorectal distention were used to determine colonic sensitivity in rats. Colon projection DRG neurons labeled with DiI were acutely dissociated for measuring excitability and sodium channel currents by whole-cell patch clamp recordings. Western blot analysis was employed to measure the expression of NaV1.7 and NaV1.8 of colon DRGs. RESULTS: STZ injection produced a significantly lower distention threshold than control rats in responding to colorectal distention. STZ injection also depolarized the resting membrane potentials, hyperpolarized action potential threshold, decreased rheobase and increased frequency of action potentials evoked by 2 and 3 times rheobase and ramp current stimulation. Furthermore, STZ injection enhanced neuronal sodium current densities of DRG neurons innervating the colon. STZ injection also led to a significant upregulation of NaV1.7 and NaV1.8 expression in colon DRGs compared with age and sex-matched control rats. CONCLUSIONS: Our results suggest that enhanced neuronal excitability following STZ injection, which may be mediated by upregulation of NaV1.7 and NaV1.8 expression in DRGs, may play an important role in colonic hypersensitivity in rats with diabetes.
