How to acquire new tumor antigens is a hotspot in cancer research currently.According to the nature of antigen epitope binding its ligand,we can identify and get unknown antigen epitope even its amino acid sequence through some analytical techniques and experiments,from T lymphocytes and monoclonal antibody levels.So the molecular mechanisms of tumor immunity will be more distinct.

Histone deacetylase 6 (HDAC6) is an unique subtype of histone deacetylases with two tandem deacetylase domains and substrate specificity for non-histone proteins. It is involved in many important physiological and pathological processes and has become a promising therapeutic target in recent decades. Different kinds of potent HDAC6-selective inhibitors have been reported around the world. This paper reviews the progress in the study of structure and functions of HDAC6 as well as the development of HDAC6-selective inhibitors.

Pleomorphic adenoma (PA) is the most common benign tumor of the salivary glands. Originating from the nasal cavity is very rare. This paper reports one case of pleomorphic adenoma of the inferior nasal turbinate to analyze the clinic characteristic of this disease. Although these tumors are rarely seen in everyday practice, one should consider this possibility as an uncommon aetiology when confronted with an intranasal mass.

AIM: To separate and determine berberine type alkaloids in Huanglian Shangqing Pills(tablets)(Rhizoma Coptidis,Fructus Gardeniae,Fructus Forsythiae,Cortex Phellodendri Chinensis,etc.). METHODS: RP-HPLC was used,and the mobile phase consisted of acetonitrile-solution of potassium phosphate(3.4 g?L~(-1),adjust pH to 3.0 with H_3PO_4)(40∶60),with 1.7 g?L~(-1) SDS.The detecting wavelength was at 345 nm. RESULTS: The contents of five kinds of berberine type alkaloids,berberine,palmatine,coptisine,epiberberine and jatrorrhizine in Huanglian Shangqing Pills(tablets) produced by 10 pharmaceutical factories were determined. CONCLUSION: The method is simple,accurate with a good recovery and repeatability.The method can be used to control the quality of Huanglian Shangqing Pills(Tablets).

Purpose:To compare the survival rates of hyperf ractionated radiotherapy plus concurrent chemotherapy with hyperfractionated rad iotherapy alone in the treatment of stage Ⅲ/Ⅳ nasopharyngeal carcinoma (NPC) a nd analyze the prognostic factors. Methods:Between December 1992 and December 1995, 144 NPC patien ts were randomized into hyperfractionated radiotherapy plus concurrent chemother apy (R +C) and hyperfractionated radiotherapy alone (R alone).Radiotherapy were similar in the two groups: 1.2 Gy/f, twice a day. Chemotherapy was given to R + C patients before and during the course of radiotherapy. Results:The 5-year overall survival rates of the R + C and R alone groups were 63.3% and 50.7%,repectively . The factors influencing the resu lts were N stage,chemotherapy and the peripheral blood hemoglobin concentration . Conclusions:Hyperfractionated radiotherapy plus concurrent chem otherapy can improve the survival rate, especially for the patients with N2-N3 stage.The negative prognostic factors for Ⅲ/Ⅳ NPC are N2-N3 stage, radiothera py alone and the reduction of hemoglobin during treatment.

AIM: To study the clinical curative effect of 2mm micro incision phacoemulsification combined with 23G minimally invasive vitrectomy for cataract and vitreoretinal diseases.METHODS: Retrospective analysis of 92 patients (99 eyes),including 49 male (53 eyes),43 female (46 eyes) with mean age was 57.1±1.9 years,in our hospital for cataract and vitreoretinal treatment of the disease from February 2013 to February 2016.All patients underwent 2mm micro incision phacoemulsification combined with 23G minimally invasive vitrectomy.Curative effect and complications were observed.RESULTS: Combined surgical procedures were carried out smoothly.posterior capsule rupture did not occurred.seven eyes were filled with BSS fluid,46 eyes with C3F8,49 eyes with intraocular lens at phase Ⅰ,21 eyes placed intraocular lens when silicone oil was removed.The visual acuity improved in 84 eyes (85%),unchaged in 15 eyes (15%).Postoperative complications included transient high intraocular pressure in 18 eyes (18%),anterior chamber reaction in 7 eyes (7%) and corneal edema in 8 eyes (8%).CONCLUSION: The 2mm micro incision phacoemulsification combined with 23G minimally invasive vitrectomy is a safe and effective surgical method with less injury,fewer complications.

Objective To observe the therapeutic effects of stellate ganglion block (SGB) with oxycodone and acetaminophen tablets on the treatment of migraine. Methods 100 patients with migraine were divided into two groups randomly. They received SGB with oxycodone and acetaminophen tablets (experimental group) or only SGB (control group) respectively. The parameters included pain intensity before and 1 d,3 d,1 w,1 m and 3 m after the treatment, and pain relief rate of each patient. The adverse effects were also evaluated. Results The pain intensity described as numeric rating score (NRS) decreased in the two groups at each time point. In the experimental group, the value of NRS was significantly less than that in the control group at 3d,1m and 3m after the treatment. The effec-tive rate ha the experimental group and the control group were 88% and 68%. Conclusion SGB with oxycodone and acetaminophen tablets is more effective for migraine and deserves widely used in patients.

Objective Investigate the effect of applying clinical pathway on the patients undergoing leiomyoma of uterus. Methods As an experimental group of patients, 50 cases of uterine leiomyoma are treated with clinical pathway. By contrast, another 100 cases are treated with the traditional medical care as control group. Results Waiting time for surgery and hospital stay of the experimental group are less than the control group; and the average hospitalization cost of experimental group is lower than the control group (P< 0.01). Conclusions Application of clinical pathway management will regulate the activities of medical treatment, ensure the quality of health care, improve the feeling of patients, increase efficiency of hospital services, reduce the financial burden of patients, increase the hospital social benefits.

Objective To evaluate the medical efficiency of sample hospitals in Sanming city before and after Sanming health care reform.Methods One tertiary hospital,two general county hospitals and two TCM county hospitals in Sanming were sampled for the study.Two dimensions(the intensity index of medical work and work efficiency index)were selected.In addition,six indexes were identified,namely the number of discharged patients,number of outpatients and emergency diagnostics,doctor′s daily workload per capita for inpatients,bed turnover times,bed utilization rate and average days of stay.Descriptive trend analysis and comprehensive index method were applied in turn to evaluate the longitudinal changes in medical efficiency at the sample hospitals before and after the medical reform.Results The five sample hospitals in Sanming were found with less days of stay in average,and three were found with year-by-year rise of medical efficiency index,with one of them rising from 1.57 to 2.42.Conclusions Sanming′s health care reform has effectively improved internal operational efficiency at the sample hospitals,and has well addressed the relationship of medical service efficiency and scale expansion.On the other hand,the relationship between work intensity and medical efficiency needs to be further balanced,resource allocation to be further optimized,and more priority to be put in the development of TCM hospitals.
