Technical Specifications for Occupational Health Surveillance (GBZ 188-2014) has played an important role in screening occupational contraindications and preventing occupational diseases since its implementation. However, during the use of occupational health examination, we found that the use of occupational contraindication on cardiovascular disease was not "homogenized" due to the differences in the understanding of various physical examination institutions. Therefore, this paper mainly discussed the connotation and quantitative standards of organic heart disease, arrhythmia, hypertension in the occupational contraindication cardiovascular disease in the specification for "homogenization".

Introduction: Flexible denture is an alternative treatment modality for removable partial denture (RPD) that aid the retention by ensuring seal around the entire border of the denture. It is also referred as hypoallergenic denture especially for those who are allergic towards conventional acrylic denture which is the poly-methylmethacrylate monomer (PMMA) and metal (cobalt chromium). The flexible material exhibits lower flexural modulus than conventional type of baseplate material denture that makes it nearly unbreakable. Nowadays, there are a handful of different flexible materials in the dental market for the general dental practitioners to choose but somehow the studies on the properties of these different types of flexible materials are sparse. Objectives: The present study is to study the development of the flexible materials, the different type of flexible materials and their physical properties. Methods: From the limited article journals available, the authors have summarized the history, development and constituents of different type of flexible materials used in fabricating denture. Besides that, the authors also discussed about the indications, contraindications, advantages and disadvantages of the materials in denture constructions based on all the published researches available on this topic using published materials available in the dental library, University of Malaya and the databases (Science Direct, PubMed). Conclusion Each flexible material has its pros and cons. Therefore, careful selection of material and understanding of the flexible dentures’ indications and contraindications are utmost importance to make sure the best treatment outcome. Hence, patients’ best interest and quality of life can be upheld.

The hidden risk of acupuncture has become the factor of the high incidence of adverse reaction of acupuncture in clinical practice. The retrospective analysis and the typical cases analysis are especially important for the prevention from the hidden risk of acupuncture. In the paper, the relevant literatures were reviewed, the basic diseases were listed such as diabetes, hypertension and digestive gastric ulcer that were neglected by the physicians, and the adverse reactions induced by the therapeutic history and the body constitutions were analyzed. It was stated in the paper that because of the individual factors of patient, the risks of the atypical clinical accidents of acupuncture were extremely serious and easily neglected by the clinical acupuncture physicians. It is very necessary to remind the clinical acupuncture physicians to understand the basic diseases, basic treatment as well as the peculiarity of body constitution of the patients besides their chief complaints. Moreover, acupuncture should be applied very carefully after identifying the pulse condition and the contraindication so as to ensure the patient's safety and obtain the optimal efficacy.

Bariatric and metabolic surgery has become the clinical hot topic of the treatment of metabolic syndromes including obesity and diabetes mellitus, but how to choose the appropriate surgical procedure remains the difficult problem in clinical practice. Clinical guidelines of American Society for Metabolic and Bariatric Surgery(ASMBS)(version 2013) introduced the procedures of bariatric and metabolic surgery mainly including biliopancreatic diversion with duodenal switch(BPD-DS), laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy(LSG). To choose the appropriate bariatric and metabolic procedure, the surgeons should firstly understand the indications and the contraindications of each procedure. Procedure choice should also consider personal condition (body mass index, comorbidities and severity of diabetes), family and socioeconomic status (postoperative follow-up attendance, understanding of potential surgical risk of gastrectomy and patient's will), family and disease history (patients with high risk of gastric cancer should avoid LRYGB; patients with gastroesophageal reflux disease should avoid LSG) and associated personal factors of surgeons. With the practice of bariatric and metabolic surgery, the defects, especially long-term complications, of different procedures were found. For example, LRYGB resulted in higher incidence of postoperative anemia and marginal ulcer, high risk of gastric cancer as well as the requirement of vitamin supplementation and regular follow-up. Though LSG has lower surgical risk, its efficacy of diabetes mellitus remission and long-term weight loss are inferior to the LRYGB. These results pose challenges to the surgeons to balance the benefits and risks of the bariatric procedures. A lot of factors can affect the choice of bariatric and metabolic procedure. Surgeons should choose the procedure according to patient's condition with the consideration of the choice of patients. The bariatric and metabolic surgery not only manages the diabetes mellitus and weight loss, but also results in the reconstruction of gastrointestinal tract and side effect. Postoperative surgical complications and nutritional deficiency should also be considered. Thereby, individualized bariatric procedure with the full consideration of each related factors is the ultimate objective of bariatric and metabolic surgery.

The NCCN has recently released its 2017 version 1.0 guideline for colorectal cancer. There are several updates from this new version guideline which are believed to change the current clinical practice. Update one, low-dose aspirin is recommended for patients with colorectal cancer after colectomy for secondary chemoprevention. Update two, biological agents are removed from the neoadjuvant treatment regimen for resectable metastatic colorectal cancer (mCRC). This update is based on lack of evidence to support benefits of biological agents including bevacizumab and cetuximab in the neoadjuvant setting. Both technical criteria and prognostic information should be considered for decision-making. Currently biological agents may not be excluded from the neoadjuvant setting for patients with resectable but poor prognostic disease. Update three, panitumumab and cetuximab combination therapy is only recommended for left-sided tumors in the first line therapy. The location of the primary tumor can be both prognostic and predictive in response to EGFR inhibitors in metastatic colorectal cancer. Cetuximab and panitumumab confer little benefit to patients with metastatic colorectal cancer in the primary tumor originated on the right side. On the other hand, EGFR inhibitors provide significant benefit compared with bevacizumab-containing therapy or chemotherapy alone for patients with left primary tumor. Update four, PD-1 immune checkpoint inhibitors including pembrolizumab or nivolumab are recommended as treatment options in patients with metastatic deficient mismatch repair (dMMR) colorectal cancer in second- or third-line therapy. dMMR tumors contain thousands of mutations, which can encode mutant proteins with the potential to be recognized and targeted by the immune system. It has therefore been hypothesized that dMMR tumors may be sensitive to PD-1 inhibitors.

OBJECTIVEThis study investigated the expression of BNIP3 in salivary adenoid cystic carcinoma (SACC) and its correlations to the clinicopathological features and prognosis of patients with SACC. The role of BNIP3 in the progress of hypoxia-induced autophagy was elucidated.

METHODSThe expression levels of BNIP3, hypoxia inducible factor (HIF)-1α, and LC3 in 65 SACC cases were detected by immunohistochemical staining method, and the correlation between the expression of BNIP3 and the clinicopathological features in SACC was analyzed. In addition, the correlations of BNIP3 gene expression with HIF-1α and LC3 gene expression were analyzed. The survival rate of patients with SACC was evaluated by univa-riate survival analysis.

RESULTSBNIP3 was considerably expressed in SACC in all three histological patterns, and was positive in 41 cases (63.1%). BNIP3 gene expression was significantly correlated with histological grade (P=0.001) and HIF-1α gene expression (P=0.011). By contrast, BNIP3 gene expression was not significantly correlated with LC3 gene expression (P=
0.167). The overall survival rate of patients with negative BNIP3 expression was better than that of patients with positive BNIP3 expression (P<0.05).

CONCLUSIONSBNIP3 might play a vital role in the tumorigenesis of SACC and may be a new target for gene therapy.

Worldwide, peroral endoscopic myotomy (POEM) has achieved remarkable initial outcomes in the treatment of achalasia. In China, POEM has developed very quickly since the first case was performed in our center in August 2010. With experience, we have successfully performed POEM for special cases (such as pediatric patients, patients with sigmoid-type esophagus, and patients with recurrent symptoms after previous surgery) and have altered our technique to achieve long-term symptom remission and simplify the POEM procedure. These changes include posterior wall incision, full-thickness myotomy, a "push-and-pull" technique for myotomy, and water-jet assisted POEM. In this article, our experiences in POEM are summarized, including changes in technique, applications of the procedure, and the management of possible complications.
