Objective Using mouse autoimmune premature ovary failure (POF) model to seek theoretical evidence for a possible clinical therapy of autoimmune POF with glucocorticoid (GC) or an-drogen. Methods After autoimmune POF was induced in 60 mice by Pzp3, the mice were randomly as-signed into 3 groups (n=20) : Two groups were treated with GC or androgen and the control group was treated with distilled water. We observed the changes in the sexual cycles of the mice, the serum level of AzpAb, infiltration of cells positively expressing CD45 in the ovary, and pathological alterations of the ovary. Results The sexual cycle of each therapy group was significantly different from that of the control group. The mean serum level of AzpAb of each therapy group was significantly lower than that of the con-trol group, and the mean serum level of AzpAb in the GC group was significantly higher than that of the androgen group. The percentage of growing follicles in the ovary of each therapy group was significantly higher than that of the control group. Ovaries infiltrated by cells positively expressing CD45 of each thera-py group were significantly fewer than those of the control group. Conclusion GC or androgen in mice with autoimmune POF could obviously ameliorate the pathogenetic conditions of the disorder, and both treatments have similar therapeutic efficacy.

The most common forms of treatment for amblyopia are occlusion therapy and pharmacologic penalization. But these methods can not recover all the visual deficits of amblyopes and there are some disadvantages of the treatment which need to be considered, including adverse effects, compliance and social stigma. Recently, some novel approaches are investigated for improving the effectiveness and compliance of treatment for amblyopia.

Objective To evaluate the effect of Ebselen on the ischemia-reperfusion injury (IRI) in rat lungs from non-heart-beating donors (NHBD).Methods Forty Sprague-Dawley rats were paired randomly divided into two groups:group Ⅰ,NHBD with 30 min of warm ischemia time (WIT); group Ⅱ,NHBD with 30 min of WIT and administration of Ebselen.The donor lungs remained ventilated at the room temperature for 30 min after asystolia and then flushed with LPD solution.The recipient rats underwent left lung transplantation.The recipients of group Ⅱ were administered with Ebselen (500 mg/kg body weight) one h before transplantation.Results All the recipients survived during the observation period.In the group Ⅱ,the MDA of the pulmonary tissue was 0.631 ± 0.23 nrmol/mg protein,and the polymorphonuclear neutrophils and the total protein of the bronchoalveolar lavage fluid were (78.4 ± 35.2) × 107/L and (0.41 ± 0.12) mg/ml respectively.The MPO was (25.09 ± 1.19) ％ and W/D was 0.359 ± 0.017.There was significant difference between group Ⅱ and group Ⅰ (all P＜ 0.05).Conclusion The administration of ebselen is an effective treatment to attenuate the acute injury resulted from the ischermia-reperfusion in the rat lungs from non-heart-beating donors.

ObjectiveTo investigate the long term effect of different antihypertensive agents on renal hemodynamics with ultrasound Doppler.Methods52 essential hypertensive patients were divided into three groups according to the antihypertensive agent they took: angiotensin-converting-enzyme inhibitor (ACEI), calcium channel blocker (CCB) and β-adrenoceptor blocker (βB). The blood pressures of right upper arms were measured with mercury column blood pressure gauge using Korotkoff method. Renal hemodynamics were examined with ultrasound Doppler before and after treatment with agents. ResultsSystolic blood pressure (SBP) and diastolic blood pressure (DBP) of all patients were decreased significantly. An significant correlation was found between the deceases of blood pressure and the betterment of renal homodynamic parameters in ACEI and CCB groups, but not in βB group. ConclusionTo a degree, the betterment of renal hemodynamics is correlation with the reduction of systemic blood pressure and mechanism of action of antihypertensive agents.

BackgroundBiological behavior of choroidal melanoma is closely related with angiogenesis.The microcirculation pattern in which tumor cells may be involved is different from neovascularization.ObjectiveThis study was to observe the microcirculation pattern of the choroidal melanoma tissue and analyze its relationship with the clinical pathology factor and the degree of cellular proliferation.Methods Forty-eight specimen of choroidal melanoma tissue were collected at Beijing Tongren Eye Centre from November 1997 through March 2006.Periodate acid Schiff staining was used to determine the microcirculation pattern of choroidal melanoma.The morphology of the tumor cells and the distribution of microcirculation pattern in the tumor were observed under a fluorescence microscopy with 544 nm wavelength,and the Ki-67 expression in the tumor was detected by immunochemistry.The relationships between the choroidal melanoma clinical pathology factor with Ki-67 expression and microcirculation pattern were evaluated by multiple stepwise regression model.ResultsA total of 9 kinds of microcirculation patterns were found by periodate acid Schiff staining.The occurring rate of loop- or network-like vascular pattern showed a significant elevation in the tumor tissue with epithelial cells in comparison with the tumor with spindle-like cells (66.7％ vs.30.6％ ) ( P=0.027 ).The expression rates of Ki-67 were 18.961 ± 10.995 and 19.481 ± 12.167 in the tumor tissue with loop- or network-like microvascular pattern,and those in the tumor tissue without loop- or network-like microvascular pattern were 10.261 ±5.669 and 12.021 ± 6.802,presenting significant differences between them ( P =0.000,P =0.010).Loop-like microvascular pattern was determined as the risk factor of the proliferation and metastasis of choroidal melanoma by multiple stepwise regression analysis (P=0.002).ConclusionsAmong the nine microcirculation patterns in choroidal melanoma,networks pattern is the most fashion,and Ki-67 expression is more strong in the tumor with epitheliod cells,suggesting that this microcirculation pattern is associated to the malignant degree and extent of proliferation in choroidal melanoma.

Objective To investigate the clinical efficacy,indications and complications of transcatheter arterial embolization for the treatment of traumatic hemorrhage of liver.Methods Retrospectively analyzed 33 cases of traumatic hemorrhage of liver admitted to West China Hospital from May 1996 to May 2006.Twenty-four cases underwent hepatic arterial angiography and were diagnosed as hepatic arterial pseudoaneurysms and followed by superselective embolization of the feeding vessel with gelatin sponge and/or spring coils.Results Embolization was succeeded technically in 28 pseudoaneurysms of 24 cases.Rebleeding occurred in 2 cases and a second embolization was performed with one recovered uneventfully.The other died of rebleeding and severe abdominal infection one week after the second embolization.Fever unrelated to embolization occurred in 9 cases.Conclusion Transcatheter arterial embolization is safe,prompt and effective for the treatment of hemorrhage due to hepatic injury.(J Intervent Radiol,2007,16:226-228)

Objective To review the clinical and histopathological features,management and outcomes in 67 patients with seba- ceous carcinoma of the eyelid.Design Retrospective case series.Participants Sixty-seven cases of the sebaceous gland carcinoma were retrieved from the ophthalmology archives of Tongren Hospital between 1996 and 2005.Methods Clinical data of all patients were re- viewed from the charts.Pathology specimens were reviewed in all cases.Main Outcome Measure Presenting features,sites of origin, location,differentiation,management,histopathologic findings,and incidence of recurrence in 67 patients.Results A total of 36 female and 31 male patients were identified.The mean age at diagnosis was 59 years (range from 35 to 84).Initial clinical diagnoses elsewhere were sebaceous carcinoma (43.28%),chalazion (25.37%),basal cell carcinoma(7.46%).Initial histopathologic diagnoses were sebaceous carcinoma(79.10%),basal cell carcinoma(5.97%),squamous cell carcinoma(1.49%) and other or not available(4.48%).The initial treat- ment involved excisional techniques with reconstruction in 42 cases,anti-inflammatory in 12 cases,without any treatment in 10 cases. 61.19% cases presented the pagetoid invasion.Local recurrence developed in 58.21% and two died from metastatic sebaceous carcino- ma (8.70%).Regional lymph node excision was performed in 13.04% because of local metastases.Five year survival rate was 94.87%. Conclusions About 1/3 cases had not receive the right treatment at initial diagnosis eyelid.The recurrence rate of patients was still high.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Objective To evaluate the necessity of indwelling gastrointestinal decompression after gastrectomy. Methods Eight publications on the necessity of gastrointestinal decompression after gastrecomy were colleted, data on recovery time of gastrointestinal function and hospital stay, complications,and motality were Meta-analyzed using fixed effect model and random effect model. Results Eight randomized trails including 975 patients were qualified and included in this study. The differences in time to oral intake ( WMD =0. 61, 95% CI: 0. 17 - 1.05, P ＜ 0. 05 ) and hospital stay ( WMD = 1.20, 95% CI:0. 05 -2. 36, P ＜ 0. 05 ) between the decompression group and non-decompression group were statistically significant, but the difference in time to flatus (WMD = 0. 31,95% CI: -0. 07- 0. 69, P ＞ 0. 05 ) was not significant. There were no significant differences in complications such as nausea and vomiting ( OR = 1.43,95% CI: 0. 61 - 3.31, P ＞ 0. 05 ), pulmonary infection and atelectasis ( OR = 1.43, 95 % CI: 0. 82 - 2. 49,P＞0.05), anastomotic leakage (OR = 1.17, 95%CI: 0.54-2.49, P ＞0.05), abdominal abscess ( OR = 1.08, 95% CI: 0. 50 - 2. 34, P ＞ 0. 05 ), wound dehiscence ( OR = 1.47, 95% CI: 0. 43 - 4. 95,P ＞ 0. 05 ) between the two groups, except for fever ( OR = 1.76, 95% CI: 1.11 - 2. 78, P ＜ 0. 05 ), which was found more frequent in decompression group than in non-decompression group. Conclusions Routine gastrointestinal decompression after gastrectomy was not conductive to the recovery of gastrointestinal function, and could not reduce the incidence of postoperative complications. Postoperative GI decompression increased fever incidence rate and prolonged hospital stay.

The effects of Wumeiwan (WMW) on TNF-alpha, IL-6, IL-8, IL-10 and NF-kappaBp65 in rats with ulcerative colitis (UC) were investigated, the curative effectiveness of WMW vs salicylazosulfapyridine (SASP) was compared, and the action mechanism was analyzed. Fifty-Six Sprague-Dawley (SD) rats were randomly divided into four groups (n=14 in each group, with equal ratio of male and female): normal control group, model group, SASP group, and WMW group. Except normal control group, the rat UC models in the remaining three groups were established using the method of 2.4-dinitrochlorobenzene (DNCB) immunization and acetic acid local enema. The rats in model group, SASP group, and WMW group were treated with distilled water, SASP, and WMW respectively. The changes in the symptoms and signs were observed, and levels of IL-6, IL-8, TNF-alpha, IL-10 and the expression of NF-kappaBp65 in the colonic tissues were statistically analyzed. The results showed that the levels of IL-6, IL-8, and TNF-alpha were significantly increased (P<0.01), while those of IL-10 significantly reduced (P<0.01) after establishment of rat UC models as compared with normal control group. The levels of IL-6, IL-8, and TNF-alpha were obviously lower, but the level of IL-10 was obviously higher in WMW and SASP groups than those in model group (P<0.05). The levels of IL-6, IL-8, and TNF-alpha were lower, while the level of IL-10 was higher in WMW group than in SASP group. NF-kappaBp65 was expressed negatively or weakly in normal colonic tissues. The positive expression rate of NF-kappaBp65 in WMW group and SASP group was obviously lower than in model group (P<0.01), and there was significant difference between WMW group and SASP group (P<0.05). It was concluded that rat UC model was established successfully. WMW could up-regulate the expression of IL-10, down-regulate the expression of TNF-alpha, IL-6, IL-8, and inhibit the NF-kappaBp65 activity to adjust immune function, indicating WMW had better curative effects on UC in rats.
