Objective:To study the role of tetrodotoxin-resistant(TTX-R)human sodium channel of hNa v1.8 mRNA in trigeminal neuralgia (TN). Methods:The samples of affected trigeminal division(inferior alveolar nerve) and non-affected division(lingual nerve) were surgically obtained from six idiopathic TN patients to whom the drug therapy was not effective.The expression of hNa v1.8 mRNA was assessed by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) with ?-actin as an internal control. A sample of great auricular nerve (from a patient who had to accept the combined radical neck dissection with glossectomy and hemimandibulectomy) and a sample of infraorbital nerve (from a patient who had to accept subtotal resection of maxilla) were used as the negative controls. Resoults:The relative amount of hNa v1.8 mRNA in the affected trigeminal divisions(1.233?0.324) was higher than that in the non-affected divisions(1.018?0.249), t=3.919,P=0.011. Conclusion:The higher expression of hNa v1.8 mRNA in the affected nerves of TN patients may play an important role in TN.

Objective To analyze the correlation between Uyghur metabolic syndrome and northwest dryness syndrome in Kashgar prefecture, Xinjiang. Methods Case-control design was used to include a total of 120 cases from the First People’s Hospital of Kashgar Prefecture, Xinjiang. They were selected as the case group, and 120 cases without diseases of Western medicine were as the control group. The northwest dryness syndrome was statistically analyzed. Results The total integral of northwest dryness syndrome in case group was (11.49±0.89) and that in control group was (5.84±0.81), and the case group was higher than the control group with statistical significance (P<0.01). By comparing various accompanied symptoms, except for the fire & wind dryness syndrome of lung&heart&spleen as well as lung&stomach yin deficiency syndrome, all the other syndromes in case group were higher than those in control group (P<0.01). The attack rate of northwest dryness syndrome in case group was 24.17% (29/120), higher than that in control group (7.50%, 9/120), with significant difference (P<0.01). In the correlation analysis between the state of TCM syndrome and northwest dryness syndrome in case group, spleen yin deficiency syndrome of metabolic syndrome had the strongest correlation with damp accumulation syndrome of northwest dryness syndrome (P<0.01), followed by liver-qi stasis syndrome and heart&kidney yin deficiency syndrome (P<0.01). Conclusion Metabolic syndrome is often concomitant with northwest dryness syndrome in Kashgar prefecture, Xinjiang. Moreover, the severity of clinical symptoms of metabolic syndrome was associated with the state of northwest dryness syndrome, which provides clinical epidemiology basis for developing prevention and cure strategy of metabolic syndrome in Xinjiang from the perspective of“treating the different diseases with the same therapy”.

砄bjective: To observe whether substance P(SP), calcitonin gene related peptide(CGRP), vasoactive intestinal polypeptide(VIP),? endorphin(? EP) are related to the pathogenesis of trigeminal neuralgia. Methods: During the attacks of trigeminal neuralgia, SP,CGRP,VIP,? EP in plasma from both external jugular and cubital fossa vein blood ipsilateral to the pain were assessed by sensitive radioimmunoassay in 16 ptients and 10 health controls, after operations the venous blood from the external jugular vein of the patients was sampled again; the external jugular vein blood of normal volunteers was collected as control. SP like and CGRP like immunoreactive positive granules of pain and painless branches were labelled using ABC immunohistochemistry methods; quantitative analysis was performed using HPIAS 1000 system. Results: During the attacks of trigeminal neuralgia, the levels of SP,CGRP,VIP in the external jugular vein blood were significantly higher than those in the cubital fossa vein blood, postoperative external jugular vein blood and the external jugular vein blood of normal volunteers. The plasma levels of ? EP in patients with trigeminal neuralgia were significantly lower than that in normal volunteers.The number and area of SP like ,CGRP like immunoreactive positive granules in the pain branches was much more and larger than those in the painless branches . Conclusion: Abnormal synthesis and release of neuropeptides in patients may be related to the pathogenesis of trigeminal neuralgia.

Objective To understand the characteristics of common causes of acute pancreatitis (AP) in China and evaluate the association of the aetiology with gender and mortality.Methods The relevant literature was searched by the China journal full-text database (CNKI),Wanfang database,Weipu database and other databases and proceeding.Based on collecting data retrieval strategy,according to the inclusion criteria selection literature,Meta analysis was performed mainly for gallstone,hyperlipidemia,alcohol and other AP from the aspects of gender and case fatality rate.Results The Meta analysis included 11 articles which were accordance with the criteria,involving 13 601 patients,including 6 732 cases of biliary AP,1 372 cases of hyperlipidemia AP and 1 169 cases of alcohol AP.The Meta analysis showed that biliary AP male to female ratio was 0.79 ∶ 1,hyperlipidemic AP male to female ratio was 1.54 ∶ 1,alcoholic AP male to female ratio was 10.47 ∶ 1,overeating AP male to female ratio was 1.29 ∶ 1,and there was significant difference (P ＜ 0.05).Alcoholic AP mortality rate was the highest,which was 2.81 times than the biliary AP and 2.46 times than the hyperlipemic AP,and there was significant difference (P ＜0.05).Conclusions Biliary tract disease is the main etiologic cause of AP in China,and there are more females than males.The mortality rate of alcoholic pancreatitis is the highest,and there are more males.But we should investigate further high-quality,large-scale trails in patients with AP.
