Objective To investigate the clinicopathologic characteristics,therapy and prognostic factors of small cell carcinoma of the cervix.Methods Clinical and pathological data of eight patients were analyzed retrospectively.Results Eight patients all presented with symptoms of abnormal vaginal bleeding or postcoital spotting.One patient had stage Ⅰ b1 disease,2 had stage Ⅰ b2 disease.2 had stage Ⅱ b disease and 3 had stage Ⅲ b disease.Histopathologic findings showed the small tumor cells had scant cytoplasm,round nuclei,absence of nucleoli,and finely dispersed chromatin.Immunohistochemical findings were positive in 7 cases for neuron-specific enolase.Three patients with stage Ⅰ b disease and 1patient with stage Ⅲb disease underwent radical hysterectomy and postoperative chemotherapy.with or without radiotherapy,and the survival period was 64,22,14 and 6 months respectively.Two patients with stage Ⅱ b disease and 2 with stage Ⅲ b disease underwent chemotherapy and radiotherapy,and the survival period was 25,9,10 and 5 months respectively.Conclusions Immunohistochemical analysis using several kinds of neuroendocrine markers is helpful in establishing the correct diagnosis in addition to focusing on characteristic histopathological features.It is necessary to use comprehensive treatment including surgery,chemotherapy and radiotherapy for patients with small cell carcinoma of the cervix.Chemotherapy may play an important role in the treatment.

Objective:To study the clinical efficacy of acupuncture for ischemic stroke and its effect on ET-1 levels in IS cases.Method:The 63 cases were randomized into a treatment group (31 cases),receiving acupuncture and routine method,and control group (32 cases),receiving routine method alone.Seven days constitute a course of treatment,a 2-day interval between two courses.The clinical efficacy and ET-1 level in two groups were compared after four weeks.Result:The total effective rate in the treatment group and control group were 96.8% and 75% respectively,with a statistical significance (P＜0.05);the ET-1 level in blood plasma also with a statistical significance after the treatment (P＜0.05);the pre-treatment and post-treatment ET-1 level in the treatment group showed a statistical significance (P＜0.01),whereas the control group didn't.Conclusion:Acupuncture is effective for ischemic stroke and can lower the ET-1 level in ischemic stroke cases.

AIM:To analyze the characteristics of optical coherence tomography ( OCT ) in diabetic optic neuropathy ( DON ) retrospectively.
●METHODS:Retrospective study. A total of 175 cases of type ll diabetes with fundus lesions from Dec. 2013 to Dec. 2015 were selected and the clinical information was collected. These cases were diagnosed by consultation between Departments of Ophthalmology and Endocrinology in the Second Affiliated Hospital of Xi′an Jiao Tong University. The results of body examination were recorded and cases were examined by color fundus photography, fluorescein fundus angiography ( FFA) and OCT. All these data were analyzed.
●RESULTS: A total of 49 cases ( 90 eyes, 25. 7%) were diagnosed DON through FFA which manifested abnormal fluorescence in optic papilla. Results of OCT showed:among 90 eyes of DON patients, 15 eyes ( 16. 7%) had normal optic nerve form; 20 eyes(22. 2%) of excavation of optic disc became smaller or disappeared, with prelaminar tissue and peripapillary retinal nerve fiber layer (RNFL) swelling;26 eyes (28. 9%) manifested optic cup deep and cup/disc ratio increasing;18 eyes (20. 0%) had tissue hyperplasia in the hollow or on the surface of optic disc; 11 eyes(12. 3%) had symptoms including vitreous traction optic papilla and optic disc rim rising. DON eyes which had similar fluorescence features could manifest different tissue morph by OCT.
●CONCLUSION: FFA defines DON by change of blood circulation in optic nerve. However, OCT can show differences of tissue morph of optic nerve that FFA fails to do. So OCT can manifest the causes and sites of optic neuropathy more clearly and also provide basis for treatment. The advantages of OCT are conducive to reviews and curative effect tracking among DON patients and these advantages including noninvasive, convenient, inexpensive and repeatable.

Objective To explore the recuperative effect of immunological function and nutritional status on the patients treated by immune enteral nutrition in early stage after severe multiple injury (SMI). Method The patients with SMI,in department of Trauma Surgery,Tongji Hospital,Tongji Medical College, Huazhong University of Science and Technology,between January 2006 to May 2007 were randomly divided into 2 groups: immune enteral nutrition group (IEN group, 20 cases), enteral nutrition group (EN group, 20 cases). The health persons served as the control group(15 cases) .Since 1st postinjury day, all patients were treated with nutritional support. The T-cell subgroup in periphera blood were detected by FCM and the level of PA, RBP, IL-2 and IL-4 in blood serum were detected by ELASA on the 1st, 3rd,5th, 8th postinjury day. Results After the treatment of IEN and EN,the serum levels of PA, RBP and the proportion of T-cell subgroup were significantly increased on the 8th postinjury day compared with on 1st postinjury day (P ＜ 0.01), but there were no differences between IEN group and EN group. The level of IL-4 were significantly decreased and the level of IL-2 were significantly increased in each group on 8th postinjury day, at same time, the level of IL-2 were significantly increased in IEN group compared with EN group (P ＜ 0.05), and the level of IL-4 were significantly decreased in IEN group compared with EN group (P ＜ 0.05). The duration of SIRS was transient and the infected complication was low on the patients treatment by IEN than EN. Conclusions On the patients with severe multiple injury, IEN was most ascendant than EN to improve the immunosuppression and clinical prognosis.

Objective To analyze the changes of varicosis and hemodynamics in cirrhotic patients with portal vein hypertension at different stages after Hassab devascularization, and to evaluate the outcome.Methods Hassab devascularization was performed in 161 patients with portal vein hypertension, who were all evaluated by means of endoscopy, Doppler color imaging and Child-Pugh grading before and 6, 12, 18,24 months after the procedure, respectively.Results The rates of mild esophageal varicosis were 44.0%,34.8% and 28.3% at 6, 12 and 18 months after Hassab devascularization, respectively, which were all significantly higher than that before the operation(7.5%, P ＜ 0.05), while the rates of severe esophageal varicosis were 25.2%, 29.7% and 34.9% at 6, 12 and 18 months after the procedure, which were significantly lower than that before(65.2%, P ＜ 0.05).The incidence of varices in gastric fundus was correlated with the severity of esophageal varices.At 12 months after the operation, the inner diameters of portal vein and its right branch significantly decreased when compared with those before(P ＜ 0.05), the maximal flow rate,volume of portal vein and average flow rate of the left branch also significantly decreased(P ＜ 0.05).At 6 months after the operation, the average flow rate of the right branch slowed down(P ＜ 0.05).Child-Pugh Grade A accounted for 63.5%, 60.6% and 57.9% at 6, 12 and 18 months after the operation, respectively, which were significantly higher than that before(48.4%, P ＜0.05).When evaluated at 24 months after the procedure, all variables were getting close to those before.Conclusion The severity of esophageal varices mitigates in 18 months after Hassab.Hemodynamics of portal vein system decreases in 12 months.The overall liver function improves in 18 months after the operation.

Objective To investigate expression level of endoplasmic reticulum stressmarker GRP78 in the testicular tissue in rats with different phases of morphine-dependence. To explore the role of ERS in morphine-de-pendence. Methods SD rats were divided into 6 groups: morphine (mor) -withdrawal group, mor-extinct group, mor-kindling group and their control groups, normal saline (NS)-withdrawal group, NS-extinct group, NS-kindling group. The experimental rats were injected with morphine subcutaneously on increasing dosage to establish the con-ditioned place preference (CPP) model. The rats in control groups were injected NS. Then the rats were suffered from withdrawal for 48 h, extinction and kindling by morphine, separately. The GRP78 expression level in testicular tissues of rats in the time point mentioned above were measured using Western Blot. Results The time of rats in the paired-box was (528.0 ± 81.0) s, which was significantly higher than that in the NS control group (P<0.001). It was (396.8 ± 116.9) s after extinctive phase, which was significantly higher than that the withdrawal phase of rats (P < 0.001). Also it was (396.8 ± 116.9) s after kindling with morphine which was significantly higher than that the extinctive phase of rats (P < 0.001). These changes of the time indicated that the animal models of extinction and kindling were established in the study. The GRP78 levels were down-regulated in 48 h after withdrawal (P <0.05), and increased a bit afterextinctive phase, but up-regulated highly after kindling with morphine (P < 0.01). Conclusion ERS may be related in the morphine dependence and it might play an important role of testicular dys-function in male drugabuser.

Full-length NS5A gene of the hepatitis C virus was amplified by PCR using plasmid pBAC25 containing HCV nonstructural gene as template. The amplified fragment (about 1.34 kb) was cloned into plasmid pQE32, and the recombinant plasmid pQENS5A was expressed in JM109 strain. The NS5A protein was purified by NiSO4 metal chelating resin, and characterized by Western-blot. Its antigenecity was determined by ELISA. The positive detection rate of anti-NS5A was 75% (69/92) in ninety-two clinic sera. The positive rate of anti-NS5A was 82.5% (33/40) in fourty positive standand sera, and the negative rate of anti-NS5A was 100% (40/40) in fourty negative standand sera. The results showed that the Full-length NS5A proteinn had the higher sensitivity and specificity in the detection of HCV antibody in sera, we suggested that NS5A protein was a useful antigen for blood screening.
