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.

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).

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.

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.

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.

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 explore the impact of juxtapapilary duodenal diverticulum on the formation of choledocholithiasis and biliary manometry after surgery.Methods The clinical data of 97 patients with common bile duct stones who successfully underwent ERCP and biliary manometry treatment from May 2011 to March 2014 were retrospectively analyzed.Ninty-seven common bile duct stone patients were divided to two groups,that is,52 cases of juxta-papilary duodenal diverticulum (experimental group) and 45 cases without juxta-papilary duodenal diverticulum (control group).The biliary manometric results before and after EST of both groups were compared.Results The basal pressure of sphincter Oddi of the experimental group before EST [(84.8 ± 26.1) mmHg] was higher than that of the control group before EST [(75.5 ± 14.6) mmHg] (P ＜ 0.05,1 mmHg =0.133 kPa);and that after EST was also higher than that of the control group after the operation[(19.8 ± 14.2)mmHg VS (15.9 ± 9.8)mmHg,P ＜ 0.05].The biliary pressure of common bile duct stone patients with JPD was higher than those without JPD before and after EST but with no significant difference(P ＞ 0.05).The biliary manometry was performed in 81 patients after one month and it was found that the basal pressure of sphincter Oddi of experimental group was still higher than that of the control group [(34.8 ± 17.1) mmHg VS (29.6 ± 15.3)mmHg,P ＜ 0.05].The biliary pressure of common bile of the experimental group was higher than that of the control group [(19.9 ± 11.2) mmHg VS (17.1 ± 13.1)mmHg,P ＜0.05].Conclusion The existence of juxtapapilary duodenal diverticulum increases the pressure of common bile duct and Oddi sphincter and leads to CBD stones.

Objective: To study the relationship between the uncomfortable symptoms and psychological state of post CABG(Coronary Artery Bypass Grafting) patients.Methods: 65 post CABG patients answered the questionaires(Symptom Inventory,Self-Rating Anxiety Scale,Self-Rating Depressing Scale).Results: The Symptom Inventory has positive correlation with the total standard points of SAS and SDS.The higher the standard scores the worse the patient's psychological state.Conclusion: Use of proper health education,psychological care and drugs can release the patients of their uncomfortable symptoms.

[Objective]To estimate the clinical effects of total hip arthroplasty(THA),bipolar and unipolar hemiarthroplasty for the treatment of femoral neck fractures(FNF) in the elderly.[Method]From February 1990 to February 2005,a follow-up study was done in 567 patients with femoral neck fractures in the elderly.The patients were divided into THA(n=275),bipolar hemiarthroplasty(n=195) and unipolar hemiarthroplasty(n=97) groups.The follow-up duration was from 3 to 15 years with an average of 8.5 years.The operation time,blood loss,volume of drainage,hospitalization time,complications and functional rehabilitation were compared.[Result]There were no statistical differences in the operation time,blood loss and volume of drainage between unipolar and bipolar hemiarthroplasty groups.There were no statistical differences in hospitalization time among the three groups.Compared with bipolar hemiarthroplasty,THR had a longer operation time and more blood loss,but had a higher functional scores and a lower rate of pain.Unipolar hemiarthroplasty had a lower functional scores and a higher rate of pain.[Conclusion]THR is especially suitable for those who are younger and active,bipolar hemiarthroplasty is suited to elderly patients,unipolar hemi-arthroplasty should be avoided because of its complications.
