Objective:To analyze the characteristics of immune status in patients with different types of oral lichen planus(OLP). Methods:197 cases of OLP,61 with reticular OLP(ROLP)and 136 with hyperaemia erosion OLP(HEOLP)were included.The im-mune status of the patients were investigated by flow cytometry (FCM)for the expression of CD3 +,CD4 +,CD8 +,CD19 +,CD16 ++56 +and CD4 +/CD8 +cells,and nephelometry for the measurements of IgG,IgA,IgM,C3 and CH50 in peripheral blood.The la-brotary norm was used as the reference and the characteristics of immune status in patients with different clinical characters of OLP were analyzed by SPSS 16.0.Results:CD3 +,CD4 +,IgA and C3 decreased,CD19 +cells,IgG,IgMand CH50 increased in patients with OLP.CD16 ++56 +,CD4 +/CD8 +cells decreased in the cases with ROLP(P<0.05);CD8 +cells decreased in the cases with HE-OLP.CD3 +,CD8 +cells were fewer in HEOLP patients than that in ROLP,CD4 +/CD8 +cells were more in HEOLP than that in ROLP(P<0.05).Conclusion:There are defects of cellular immune function and increase of humoral immune in patients with OLP. The patients with different clinical types of OLP may have different immune fuction changes.

Chronic pain is a common clinical disease,which brings great burden to the patients.However,the pathogenesis underlying of chronic pain is complicated,which is affected by many factors,such as physiology,psychology and society.Therefore,the treatment of chronic pain has been a problem in clinical practice.Considering its complexity,a single way of treatment usually could not reach satisfactory results,so combination therapy is often used to treat chronic pain at present.The combination therapy includes pharmacological treatment,psychological approaches,interventional treatment,self management and so on.The treatment plans are distinct for different types of chronic pain,even the individual patients with the same kind of pain.The emergence of interdisciplinary rehabilitation programs shed light upon the treatment of chronic pain recent years.This paper reviewed the research on chronic pain treatment,in order to provide theoretical basis for clinical practice.

AIM:To compare the effects of alcohol and aqueous extracts from Huiyang shengji gao(HYSJG),a Chinese medicine,on proliferation of human fibroblasts derived from normal and ulcer margin skin.METHODS:Using explant culture techniques,we obtained populations of normal human fibroblast(nHFB)and ulcer marginal fibroblast(uHFB).Alarmar blue assay was used for observing cell proliferation,and flow cytometry for cell cycle analysis.RESULTS:After cultured with aqueous extracts and alcohol extracts of HYSJG for 24 hours,the proliferation rates of the two cell lines were both elevated.For alcohol extract,obvious proliferation-promoting concentrations on nHFB and uHFB were 0.027-0.425 mg/L and 0.027-0.213 mg/L,respectively(P

Objective To investigate the expression of p53 up-regulated modulator of apoptosis (PUMA) and p53 protein and relationship with clinicopatbological parameters in human gastric cancers. Methods Primary gastric carcinoma and adjacent normal mucosa were obtained from 84 consecutively enrolled patients undergoing gastric cancer resection at Peking University People's Hospital during the period from April 2001 to May 2003. Immunohistochemistry staining was used to measure the expression of PUMA and p53 proteins both in normal and malignant tissues. Results PUMA expression is significantly weaker in primary gastric carcinoma compared to adjacent normal mucosa (P <0. 01 ). Weak PUMA expression in gastric cancer correlates with depth of tumor invasion ( P < 0. 01 ), advanced pTNM stage ( P < 0. 05 ) and poor overall survival of patients ( P < 0. 05 ). p53 protein expression in gastric carcinoma is significantly higher than adjacent normal mucosa ( P < 0. 01 ). There was a significant negative correlation between the expression of PUMA protein and p53 protein in gastric carcinoma (P < 0. 05 ). Conclusion PUMA expression in gastric carcinoma is significantly lower compared to adjacent normal mucosa. Weak PUMA expression in gastric cancer correlates with depth of tumor invasion, later pTNM stage and poor overall patient survival.

Based on the character of the molecular structure, the prodrugs of phosphates and phosphonates were divided into two categories. The first is the drug which contained the phosphate group, introducing protected groups to increase lipophilicity and improve bioavailability. The other one is the drug which had no phosphate group, introducing the phosphate group into molecules to enhance the solubility, regulate the distribution coefficient and enhance the drug-like property. This review focuses on the application of phosphates and phosphonates in drug research and development based on improvement of physico-chemical property, drug safety and the pharmacokinetics.

Objective To explore the feasibility,safety and efficacy of laparoscopy assisted ultrasound guided radiofrequency ablation (RFA) in the treatment of hepatocellular carcinoma (HCC) beneath the diaphragm.Methods Twentythree consecutive patients with solitary HCC beneath the diaphragm were treated by laparoscopy assisted ultrasound guided RFA in the Chinese PLA General Hospital from January 2013 to March 2016.We observed the p erioperative complications and followedup long-term effect.Results All the 23 patients successfully underwent laparoscopy assisted ultrasound guided radiofrequency ablation.No serious complications such as massive hemorrhage,biliary fistula and severe pleural effusion,hemopneumothorax occurred in the patients during perioperative period.CT examination 2-3 days after the operation revealed that the tumor was completely covered by the ablation area.Besides,the survival condition was satisfactory during follow-up period of 9-38 months.Conclusion Laparoscopy-assisted ultrasound-guided radiofrequency ablation is effective and safe for HCC beneath the diaphragm.

Aim To evaluate the endothelial dysfunction level of different arteries at different stages of SHR,and the recovery after administration.Methods SHR model was used,captopril(3.375 g·kg~(-1)·d~(-1)) was administered from week 7 to week 24 and the effects were observed continuously until 8 weeks post treatment.Pathological changes of aorta,mesenteric and apex cordis arteries were examined at the time points of 6,18,24,32 wk,and the endothelial-dependent relaxation of the former two preparations were tested by acetylcholine(ACh)(n=6).Results There were pathological changes in the thoracic aorta,mesenteric artery and arteriole at 18 wk,and aggravated along the age.The thoracic aorta demonstrated the most severe pathological changes appearing endothelial cells ablated and tunica media thickening.The significant decline of endothelium-dependent relaxation in aorta,and mesenteric arteries of SHR reflected an aging dependent change of vascular function with the most severe situation in the aorta(P=0.10,18 wk,P<0.01 24,32 wk);captopril increased the aorta vasodilatation of SHR at 18 wk time point,without the effect in mesenteric artery(P<0.05 vs SHR).Conclusions During the progress of SHR,endothelial damages have been observed in all three kinds of vasculatures together with the reduced endothelial-dependent relaxation.The aorta presents earlier and deeper damage than middle and small size vessels,and is sensitive towards the antihypertensive therapy such as the angiotensin converting enzyme inhibitor.

Objective:To estimate the probability of N2 lymph node metastasis and to assist physicians in making diagnosis and treatment decisions.Methods:We reviewed the medical records of 739 patients with computed tomography-defined stage Ⅰ non-small cell lung cancer ( NSCLC ) that had an exact tumor-node-metastasis stage after surgery.A random subset of three fourths of the patients ( n =554 ) were selected to develop the prediction model.Logistic regression analysis of the clinical characteristics was used to estimate the independent predictors of N2 lymph node metastasis.A prediction model was then built and externally validated by the remaining one fourth ( n=185 ) patients which made up the validation data set.The model was also compared with 2 previously described models.Results:We iden-tified 4 independent predictors of N2 disease:a younger age, larger tumor size, central tumor location, and adenocarcinoma or adenosquamous carcinoma pathology.The model showed good calibration ( Hos-mer-Lemeshow test:P=0.923) with an area under the receiver operating characteristic curve (AUC) of 0.748 (95%confidence interval, 0.710-0.784) .When validated with all the patients of group B, the AUC of our model was 0.781 (95% CI: 0.715 -0.839) and the VA model was 0.677 (95% CI:0.604-0.744) (P =0.04).When validated with T1 patients of group B, the AUC of our model was 0.837 (95%CI:0.760 -0.897) and Fudan model was 0.766 (95% CI: 0.681 -0.837) (P <0.01) .Conclusion:Our prediction model estimated the pretest probability of N2 disease in computed tomography-defined stageⅠNSCLC and was more accurate than the existing models.Use of our model can be of assistance when making clinical decisions about invasive or expensive mediastinal staging procedures.
