Objective To investigate the effects ofviaminate on the proliferation and differentiation of HaCaT cells,a human keratinocyte cell line.Methods Cultured HaCaT cells were treated with various concentrations (2,5,10,15,20,25 and 30?g/mL) of viaminate for various durations.The cell proliferation was assessed by MTT method,the changes of cell cycle and apoptosis rate by flow cytometry,the changes of keratin 10 and involucrin mRNA expressions by semi-quantitative reverse transcription PCR.Results The proliferation of HaCaT cells was inhibited by the treatment with viaminate of≥2?g/mL for 48 h,and the inhibition rate was raised with the increase of treatment time and dosage.The viaminate of 30?g/mL inhibited the proliferation of HaCaT cells by 57.67% and 82.00% at 48 and 72 h after the incubation respectively,and elevated the mRNA expression of involucrin from 40.80% to 156.12%,decreased the mRNA expression of keratin 10 from 96.46% to 14.60%.The mRNA expression of involucrin increased with the elevation of viarninate dosage.Under the treatment with viaminate for 48 h,the cell population at G_1 phase significantly increased,that at S and G_2 phases decreased;the switching of G_1 to G_2 was inhibited;but the cell apoptosis was not affected.Conclusion Viaminate could inhibit the proliferation and induce the differentiation of keratinocytes.

Objective To explore the inhibitory effect of the ethanol extract from peanut root on the non-castration adult rat prostate hyperplasia induced by testosterone propionate and its mechanism .Methods 60 SD rats were randomly divided into the control ,model and high ,middle and low dose of peanut root ethanol extract treatment groups ,among them ,the control group was normally fed without medication ;the model group was subcutaneously injected by testosterone propionate (TP ,5 mL/kg/d) and simultaneously gavaged subcutaneous injection with peanut root ethanol extract (10 mL/kg/d ,5 mLg/kg/d or 1 mL/kg/d) for suc-cessive 14 d .The rats in various groups were killed on 15 d and their prostate ,spermatophore and testicle tissues were separated and weighed .The ratio of gland/body-weight(mg/g) was calculated .The expressions of Bcl-2 and Bax proteins in the prostate tissues were detected by immunohistochemistry .Results There was statistical difference in the indexes of prostate between the treatment groups(high and middle dose) and the model group(P<0 .01) ,while there was no statistical difference between the low dose group and the model group(P>0 .05) .This result showed that there was a dose-effect relationship between the inhibition effect on rat prostate hyperplasia and the ethanol extracts from peanut root .There was no statistical differences between the model group and the treatment groups in the indexes of testicle ,spermatophore or the change of weight (P>0 .05) .There was statistical difference be-tween the control group or model group and the treatment group in the expression of Bcl-2 or Bax protein(P<0 .05) ,while no sta-tistical difference between the treatment group and the control group (P>0 .05) .Conclusion Ethanol extract from peanut root has good inhibiting effect on prostate hyperplasia and its mechanism could reach the curative effect by regulating the balance relation be-tween apoptosis gene Bcl-2 and Bax protein proportion and promoting apopitosis of benign prostatic hyperplasia .

Objective To investigate the effect of pioglitazone (PIO) on the expression of peroxisome proliferators-activated receptor γ (PPARγ),nuclear factor-κB (NF-κB) c-Rel and anti-apoptosis factor Bcl-xL in cultured Wistar rat cortical neurons after oxygen-glucose deprivation/reoxygenation (OGD/R).Methods The rat cerebral cortical neurons were primarily cultured in vitro and a model of OGD/R was induced.The rats were divided into 7 groups:normal,OGD 4 h/R 6 h,OGD 4 h/R 12 h,OGD 4 h/R 6 h + PIO,OGD 4 h/R 6 h + PPARγ inhibitor T0070907 (TIO),OGD 4 h/R 12 h + PIO,and OGD 4 h/R 12 h + TIO groups.Western blot was used to detect the expression of PPARγ and NF-κB c-Rel protein in neurons.Reverse transcriptionpolymerase chain reaction assay was used to detect the expression of Bcl-xL mRNA in neurons.Results Western blot analysis showed that the expression levels of PPARγ and NF-κB c-Rel proteins after OGD/R were increased significantly compared to those of the normal group (P ＜0.01).After giving PIO,the expression levels of PPARγ and NF-κB c-Rel proteins were further increased,and they were significantly higher than those in the OGD 4 h/R 6 h and OGD 4 h/R 12 h groups (P ＜0.01),and after giving TIO,the expression levels of PPARγ and NF-κB c-Rel proteins were decreased,and they were significantly lower than those in the OGD/R group (P ＜0.05) and the corresponding PIO group (P ＜0.01).Reverse transcription-polymerase chain reaction analysis showed that the expression level of Bcl-xL mRNA in the OGD 4 h/R 6 h group was significantly higher than that in the normal group (P ＜0.01).The expression level of Bcl-xL mRNA in the PIO group was significantly higher than that in the OGD 4 h/R 6 h and OGD 4 h/R 12 h groups (P ＜0.01).After giving TIO,the expression of Bcl-xL mRNA was decreased.It was significantly lower than that in the OGD/R and corresponding PIO groups (P ＜ 0.05 and P ＜ 0.01).Conclusions PIO can upregulate the expression of PPARγ protein in cultured cortical neurons after OGD/R,and then increase the expression of anti-apoptotic factor Bcl-xL mRNA of NF-κB c-Rel regulation.This may be the part mechanism of PPARγ neuroprotective effect.

Objective To discuss the diagnosis and surgical management of acute gangrenous cholecystitis (AGC) early after EST and ERCP. Methods Clinical and pathological data of 1468 cases receiving EST and ERCP in our hospital from 2005 to 2007 were retrospectively analyzed. Results AGC occurredin 16 cases and the incidence was 1.09%. Its main manifestations were pain in the right upper abdomen with local pertonitis and fever 1 to 3 d after operation, blood WBC exceeding 15.0× 109/L in 15 cases (93.8%), gallbladder tumefaction and double layer structure by B mode ultrasound, the diagnostic accuracy before operations was 81.3 %. We performed cholecystectomy in 10 cases, cholecystectomy and choledochotomy for common bile duct exploration and stone removal and T-tube drainage in 2, partial cholecystectomy in 3, cholecystostomy in 1. Pathological examination showedthat it was AGC in all the patients. Conclusion Latency in 1 to 3 d, local pertonitis, high blood WBC and B mode ultrasound are main managements in diagnosis of AGC and it should be diagnosed carefully distinguished from perforation and severe acute pencreatitis. It is suggested to undergoing early surgi-cal management once diagnosed definitely.

Objective To summarize the clinical and pathological features of exaggerated placental site (EPS),explore its pathogenesis regularity,diagnosis and treatment strategies.Methods The clinical data related to 34 patients with EPS were analyzed retrospectively.Results In 34 patients,11 patients performed full-term cesarean section,2 patients performed normal vaginal delivery,the other 21 patients had abortion.Thirty-one patients had pregnancy history.Fifteen patients performed hysterectomy,13 patients performed dilatation and curettage,6 patients performed exploratory hysteroscopy and lesions resection.All the patients survived after treatment.Conclusions The patients can not be diagnosed in the antepartum and intrapartum,but can be diagnosed relying on the pathological diagnosis.When it is ineffective to stop bleeding after delivery or abortion by conventional treatment,we should consider the possibility of EPS.Timely perform hysterectomy is theeffective method to stop bleeding,can save the life of patients.If bleeding is not much,curettage or exploratory hysteroscopy can get a significant effective treatment and avoid hysterectomy.

Objective To investigate the safety of thalidomide in the treatment of immune-related bowel diseases for providing clinical reference.Methods Thirty-five patients with immune-related bowel diseases (31 Crohn's disease,2 ulcerative colitis and 2 Behcet's disease) treated with thalidomide were enrolled in this study.The incidence,type,severity,duration of thalidomide related adverse drug reaction (ADR) and the dose-effect relationship of neurotoxicity were analyzed.Results All the patients were treated with a mean dose of thalidomide (109.29 ± 30.37) mg/d for (18.8 ± 12.4) months,and 33 occurred ADR.The three most frequent ADR were numbness [51.4％ (18/35)],somnolence [48.6％ (17/35)] and dermatitis [37.1％ (13/35)].The median time to development of these three ADR were 6.50,0.25,and 1.00 months,respectively.Severe ADR leading to withdrawal accounted for 20.0％ (7/35),including reasons of peripheral neuritis (3/7),dermatitis (2/7) and myelosuppression (2/7).The incidence of peripheral neuritis was not significantly related to the maximal and initial dose of thalidomide (P ＞ 0.05).Conclusions Although the incidence of ADR was relatively high during the treatment of thalidomide,most of them were mild and well tolerated.Thalidomide can be safely used in patients with immune-related bowel diseases under close monitoring.

OBJECTIVE: To provide anantomical basis for the endoscope-assisted partial superficial parotidectomy via retroauricular hairline approach (EASPRHA) and assess its feasibility and safety. METHOD: The surgical anatomy of retroauricular hairline region and parotid gland region were observed in 15 fresh human cadavers (30 halves). The EASPRHA was performed on 5 human cadavers (10 halves). After the procedure, the related vascular and neural structures were evaluated. RESULT: The retroauricular hairline region extends between superficial musculoaponeurotic system and superficial cervical fascia. On the superficial surface of the upper sternocleidomastoid lie the lesser occipital nerve, the great auricular nerve and the external jugular vein. The bifurcation of great auricular nerve is(22.85 ± 2.01) mm from the bottom of earlobe. The parotid gland region extends between parotidomassteric fascia and parotid gland parenchyma. The facial nerve emerging from the stylomastoid foramen runs across the superficial surface of base of styloid process, passes through the interspace between cartilage of external acoustic meatus and posterior belly of digastric muscle, and enters the parotid gland. The bifurcation of facial nerve trunk is (19.10 ± 3.10)mm from the mastoidale and (39.49 ± 5.78) mm from the mandibular angle. Above the posterior belly of digastric muscle, the posterior auricular artery arises from the posterior wall of the external carotid artery with its main stem running over the superficial surface of facial nerve trunk. In all endoscope-assisted operations, the partial superficial parotidectomy was successful without the need for an additional incision. No major neurovascular damage wasobserved. CONCLUSION A thorough knowledge of the surgical anatomy of retroauricular hairline region and parotid gland region is an essential requirement in performing the safe and feasible EASPRHA.
