The zinc finger protein A20 exists in many kinds of ceils in the body and plays multiple roles in physiological and pathological processes such as regulation of immune response,inflammatory diseases and cancers by inhibiting cell apoptosis induced by tumor necrosis factor (TNF) and restricting NFKB signaling pathway.Recently,the role of A20 in generation and development of tumors draws wide attention,hence,we summarized recent research progress of the relation between A20 and cancer in this review.

Objective To investigate the effect of different pressures of hyperbaric oxygen (HBO) treatment on neuropathic pain (NP) in rats.Methods Twenty-four healthy male Sprague-Dawley rats were randomly divided into 4 groups (n =6 each):sham operation group (group S),NP group,treatment with HBO at 2.0 atmosphere absolute group (group HBO2.0) and treatment with HBO at 2.5 atmosphere absolute group (group HBO2.5).The animals were anesthetized with intraperitoneal 5 ％ chloral hydrate 300 mg/kg.NP was induced by chronic constrictive injury.The left sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1-mm intervals with 4-0 silk thread.After the rats were placed in the HBO chamber,the pressure was increased at a rate of 10 kPa/min until the desired pressure was reached,and then the pressure was maintained at this level for 60 min.The pressure was then decreased at a rate of 10 kPa/min until the normal pressure was reached.HBO treatment was performed once a day for 5 consecutive days starting from 1st day after operation in groups HBO2.0 and HBO2.5.While the rats were only placed in the HBO chamber and stayed for 100 min in groups S and NP.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 0,1and 2 h after leaving the HBO chamber (T0.2).Results Compared with group S,MWT was significantly decreased and TWL was shortened in group NP (P ＜ 0.05).Compared with group NP,MWT was significantly increased and TWL prolonged at T1 during the treatment (P ＜ 0.05),while no significant change was found in MWT and TWL at T2 during the treatment in groups HBO2.0 and HBO2.5 (P ＞ 0.05).There was no significant difference in MWT and TWL at each time point during the treatment between groups HBO2.0 and HBO2.5 (P ＞ 0.05).Conclusion Treatment with different pressures of HBO can reduce NP in rats,but the change in pressure dose not affect the analgesic efficacy.

Objective To explore the effect of intraoperative parathyroid hormone (IOPTH) examination on parathyroidectomy for primary hyperparathyroidism.Methods The clinical data of 41 PHPT patients who received IOPTH monitoring (IOPTH group) from Jan.2009 to Dec.2014 were retrospectively analyzed.The clinical manifestation,examination and changes of parathyroid hormone and calcium before and after operation were collected.Results There were 12 males and 29 females.36 cases had parathyroid adenoma,and 5 cases were parathyroid carcinoma.23 cases were positive in 24 cases of 99Icm-MIBI parathyroid adenoma radionuclide examination,and 2 cases were positive in 3 cases of parathyroid carcinoma radionuclide 99Tcm-MIBI inspection (P＝ 0.213).10 mins after tumor resection,PTH in all cases decreased by 50％ or more than that before tumor resection except for one case of parathyroid carcinoma.23 cases appeared hypocalcemia in 36 cases of parathyroid adenoma after surgery and 2 cases appeared hypocalcemia in 5 cases of parathyroid cancer patients (P＝0.361).No postoperative hoarseness,cough,bleeding occoured.Patients were followed up from 6 to 72 months.Hypocalcemia symptoms recovered 2 weeks to 3 months after surgery.No permanent hypoparathyroidism occured.One case of parathyroid carcinoma died of hypercalcemia 5 months after surgery.The remaining 40 cases survived without recurrence or death.Conclusions Intraoperative PTH monitoring can help doctors analyze whether all the hyperthyroidism glands have been removed,which can help to avoid miss diagnosis of multiple gland disease and unnecessary bilateral neck exploration.This method is highly accurate so it is recommended for routine use in PHPT surgery.

OBJECTIVETo analyze the incidence and survival rates of primary liver cancer (PLC) among residents in Yangpu district of Shanghai.

METHODSA total of 9 730 736 permanent residents (male 4 996 390 and female 4 734 346) of Yangpu district in Shanghai were recruited in the study between year 2002 and 2010; among whom 2726 PLC cases were diagnosed and 2427 death cases were certified. The incidence and mortality of PLC were calculated under the analysis of the new PLC cases and death cases between year 2002 and 2010. The rates were standardized by the demographic composition developed in the Fifth Nationwide Census in year 2000, in order to analyze the survival condition of PLC patients and explore the prognosis of surgical excision treatment.

RESULTSAmong the new PLC cases between year 2002 and 2010, 1966 cases were male, whose average age of onset was 59.81; while 760 cases were female, whose average age of onset was 68.93. The crude incidence rate was 39.35/100 000 in male, which was higher than it in female, as 16.05/100 000. The difference showed statistical significance (U = 7.32, P < 0.01). The standardized incidence rates were 21.98/100 000 and 6.96/100 000 in male and female, respectively. The difference showed statistical significance (U = 221.76, P < 0.01). There were 2427 PLC death cases in total, including 1734 male death cases and 693 female death cases. The crude mortality rate was 34.71/100 000 in male and 14.64/100 000 in female, whose difference were statistically significant (U = 6.68, P < 0.01). The standardized mortality rate was 19.16/100 000 in male and 6.06/100 000 in female, whose difference were statistically significant (U = 207.18, P < 0.01). The incidence and mortality rates both increased apparently since males aging over 35 and females over 45. The 1 - 5 year survival rates of PLC patients were 33.95%, 23.11%, 17.04%, 14.42% and 12.29%, respectively. In the surgical excision treatment group (321 cases), the 1 - 5 year survival rates were separately 66.78%, 52.87%, 41.88%, 33.57% and 32.64%; while in the non-surgical treatment group (2405 cases), the 1 - 5 year survival rates were separately 29.04%, 18.58%, 13.30%, 11.16% and 9.01%. The differences in 1 - 5 year survival rates between surgical and non-surgical groups all showed statistical significance (U = 12.78, 10.52, 8.28, 5.56 and 5.12, respectively, P < 0.01).

CONCLUSIONThe incidence of PLC was close to its mortality in Yangpu district of Shanghai. The male incidence and mortality rates were significantly higher than female corresponding rates. The surgical excision treatment could improve the prognosis of PLC.

OBJECTIVETo evaluate a new type of diatomite-based machinable ceramic biocompatibility by studying its induced apoptosis on L929 cell in contrasted with other prosthodontics materials.

METHODSCell line was treated with extracting liquid containing different concentrations of diatomite-based machinable ceramic and other materials. Flow cytometry tested cell cycle progression and induced cell apoptosis. Annexin V-FITC/PI apoptosis staining kit quantitative detected cell death patterns. The expression of Bcl-2 and Bax mRNA were determined by reverse transcription-polymerase chain reaction.

RESULTSThe experimental groups had no special influence on cell cycle. Apoptosis rates of the new ceramic closed to the negative group (P > 0.05). The apoptosis rate of resin was the highest, and the cell necrosis level of resin was increased, which had significant difference to the new ceramic (P < 0.05). The Bcl-2 and Bax mRNA levels of the new ceramic and the negative group were closed to each other, which had no statistical significance (P > 0.05).

CONCLUSIONThe new diatomite-based machinable ceramic has no apparent cytotoxicity, which is consistent with the clinical application of the basic requirements of biocompatibility.

Serum pharmacochemistry of traditional Chinese medicine (TCM) is designed to screen the efficacy material base of TCMs from the constituents absorbed into the blood after oral administration. The theory and method is in accordance with the effect characteristics of TCMs, and reflects the interaction between the body and the drugs, has become an effective pathway for researching the efficacy material base of TCMs which has been recognized and used widely. In the paper, the previous research contents and methods of the serum pharmacochemistry of TCM were reviewed, and on the basis of the further validity of the special administration form of the TCM formula and the corresponding property to TCM syndrome, the new strategy of serum pharmacochemistry of TCM integrating the metabonomics technologies was put forward. According to the strategy, we take the biological characters of TCM syndrome as a research starting point, taking TCM formula as object, using the metabolic biomarkers of syndromes or disease to evaluate the therapeutic effect of formula and screen the compounds of TCMs in serum which are highly correlated with the metabolic biomarkers through the correlation analysis, and by further biological validation to finally confirm the efficacy material basis of TCMs. Integrating with the systems biology technologies, the theory and method of serum pharmacochemistry of TCM will further develop, and open a new chapter in the interpretation of the theory of TCM.

OBJECTIVETo analyze the incidence and mortality of lung cancer patients among residents in Yangpu District of Shanghai from 2002 to 2010.

METHODSThe data of lung cancer cases in permanent residents of Yangpu district were collected from the database of the registration and management system in Shanghai city. Temporal trend in the incidence of lung cancer was analyzed by using annual percent change (APC) mode1. The survivals were calculated using SPSS 16.0 and Joinpoint Regression Program 3.5.1 software.

RESULTSA total of 5726 cases of lung cancer were diagnosed from January 2002 to December 2010. Of those, 3865 were males with an average age of onset 70.08 years, and 1861 were females with an average age of onset 70.88 years. The crude incidence rate was 77.36/10(5) in men, significantly higher than 39.31/10(5) in women (U = 24.84, P < 0.01). The standardized incidence rate was 25.23/10(5) in men, significantly higher than 13.47/10(5) in women (U = 13.24, P < 0.01). A total of 5248 cases died of the disease in this period. Of those, 3586 were men. The crude mortality was 71.77/10(5) in men, significantly higher than 35.11/10(5) in women (U = 24.67, P < 0.01). The standardized mortality was 21.72/10(5) in men, significantly higher than 11.08/10(5) in women (U = 13.01, P < 0.01). Both the incidence and mortality rates increased apparently in those older than 45 years. The 1- to 5-year survival rates in all cases were 37.42%, 22.71%, 15.73%, 12.32%, and 10.53%, respectively. The 1- to 5-year survival rates in male cases were significantly lower than those in female cases (P < 0.05 for each comparison). The 1- to 5-year survival rates of the patients whose tumor had been surgically removed were significantly higher than those in the patients without surgery (P < 0.05 for each comparison).

CONCLUSIONSThe incidence of lung cancer is close to the mortality in the residents of Yangpu District of Shanghai city. Surgical resection treatment improves the prognosis of lung cancer.
