Objective To evaluate the effects of preoperative regional artery chemotherapy (PRACT) on gastric carcinoma. Methods Celiac arteriography was performed by transfemoral artery catheter according to Seldinger's method and superselective catheterization proceeded to the supplying artery of focus of lesion. Antineoplastic agents of Fluorodeoxyuridine (FUDR)(0.8 g/m 2), epirubicin(40 mg/m 2), oxaliplatin(80 mg/m 2) were infused into regional artery by a single administration. The specimens from 14 cases of gastric carcinoma(GC) who received PRACT were separated into pre operation group and post operation group. Both microscopic study to observe the necrosis of cancer cell and TUNEL(TdT mediated dUTP nick end labeling) method to detect the state of apoptosis were performed respectively in the two groups. Correlation of apoptosis index (AI) between the two groups, as well as correlation between the situation of necrotic tumor cell and the blood vessel, was analyzed. Results The severity of the necrosis of tumor cell was significantly higher in the PRACT group than that in the untreated group ( P

OBJECTIVE:To investigate the characteristic and regularity of antineoplastics-induced ADR,and to provide refer-ence for safety use of antineoplastics in clinic. METHODS:In retrospective study,309 cases of antineoplastics-induced ADR col-lected from a special hospital during Jan.-Dec. 2015 were summarized and analyzed statistically. RESULTS:Among 309 ADR cas-es,female (58.25％) was more than male (41.75％). The patients aged more than 40 years old occupied the highest proportion (78.64％). Main route of administration was intravenous dripping(94.82％). There were 225 cases of severe ADR(72.82％). To-tal 268 cases were improved after drug withdrawal or treatment(86.73％). A total of 24 kinds of antineoplastics were involved in 309 ADR cases;most of ADR were induced by docetaxel,followed by cisplatin,cyclophosphamide. Most common organs/system involved in ADR was hemopoietic system (64.24％),main clinical manifestation was myelosuppression. CONCLUSIONS:It is necessary to strengthen ADR monitoring,prevent,discover and treat antineoplastics-induced ADR timely,in order to reduce the harm to the patients and ensure the safety and effectiveness of drug treatment.

OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

Objective To assess the effects of cyclic stretch on fibroblast orientation in order to find the appropriate cyclic stretch to cause maximum fibroblast orientation and to explore the mechanism of cell signalling since cells are known to orient in response to the application of mechanical forces. Methods Human forehead dermal fibroblasts were seeded onto collagen coated flexible membranes. Membranes were then deformed at 10 cycles per minute by the application of 135 mmHg subatmospheric pressure. This corresponded to strain levels of 0% to 24% from the center to extremity of the flexible membrane. Cells orientation angles were studied by inverted microscopy. Integrin ?1 distribution were studied with immunocytochemical staining and confocal microscopy. Integrin ?1 expression and focal adhesion kinase ( FAK) phosphorylation were analyzed with Western blot analysis. Results A minimum of 15% cell stretch was required to significantly stimulate the fibroblast orientation response. Cyclic stretch induced integrin ?1 redistribution and FAK phosphorylation. Incubation of cells with anti-integrin ?1 prior to the application of stretch abrogated fibroblast orientation and FAK phosphorylation. Conclusion Fibroblast orientation in response to cyclic stretch is mediated at least in part by integrin ?1 through phosphorylation of FAK.

Objective To investigate the regulatory effects of endogenous sulfur dioxide (SO2) on collagen accumulation in pulmonary arterial fibroblasts of rats and its mechanisms.Methods Primary rat pulmonary artery fibroblasts were used in the experiment and were divided into 3 groups:the control group,the L-aspartate-beta-hydroxamate(HDX) group and the HDX ± SO2 group.SO2 content of pulmonary artery fibroblasts supernatant was detected by adopting high performance liquid chromatography (HPLC).Collagen type Ⅰ and collagen type Ⅲ in pulmonary artery fibroblasts were determined by using immunofluorescence.Phosphorylation of Smad2/3,protein expression of matrix metalloproteinase (MMP)-13 and tissue inhibitors of MMP (TIMP)-1 were detected by using Western blot.One-way ANOVA was used for multiple group comparisons followed by Bonferroni test for each group.P ＜ 0.05 was considered as significant difference.Results Compared with control group,endogenous SO2 content in HDX group was significantly decreased [(14.30-± 0.48) μmol/L vs.(20.14 ± 0.49) μμmol/L,P ＜ 0.01],the level of Smad2/3 increased (1.03 ±0.31 vs.0.48 ± 0.20,P ＜ 0.01),protein expressions of MMP-13 and TIMP-1 in pulmonary artery fibroblasts were decreased (MMP-13:0.28 ± 0.06 vs.0.75 ± 0.11,P ＜ 0.01;TIMP-1:0.40 ± 0.05 vs.0.66 ± 0.20,P ＜ 0.01),and the ratio of MMP-13/TIMP-1 was decreased (0.71 ± 0.12 vs.1.23 ± 0.45,P ＜0.01).However,contents of collagen Ⅰ and collagen Ⅲ were significantly increased.Compared with HDX group,the level of Smad2/3 phosphorylation in HDX ± SO2 group decreased (0.57 ± 0.16 vs.1.03 ± 0.31,P ＜ 0.01),protein expression of MMP-13 and TIMP-1 upregulated (MMP-13:0.63 ± 0.06 vs.0.28 ± 0.06,P ＜ 0.01;0.59 ± 0.11 vs.0.40 ± 0.05,P =0.015),the ratio of M MP-13/TIMP-1 (1.10 ± 0.22 vs.0.71 ± 0.12,P =0.033) increased,but contents of collagen type Ⅰ and type Ⅲ were reduced obviously.Conclusions SO2 promotes the degradation of collagen and collagen accumulation in pulmonary artery fibroblasts of rats probably by inhibiting Smad2/3 signal pathway,increasing protein expression of MMP-13 and TIMP-1,and upregulating the ratio of MMP-13/TIMP-1.

BACKGROUND: It is commonly believed that hyperbaric oxygen (HBO)plays a neuroprotective role in the prevention and treatment of cerebral infarction (CI), however hyperbaric oxygen therapy (HBOT)-induced CI was also reported.OBJECTIVE: To investigate the risk factors of HBOT-induced CI.DESIGN: Case analysis with patients as subjects.SETTING: At the Department of Hyperbaric Oxygen of Guangzhou General Hospital of Guangzhou Military Command Area of Chinese PLA.PARTICIPANTS: Totally 192 inpatients receiving HBOT were selected from the Department of Hyperbaric Oxygen of Guangzhou General Hospital Guangzhou Military Command Area of Chinese PLA between December 1996 and March 1998, including 127 males and 65 females with age ranging from 9 to 78 years old. Totally 6 patients, 3 males and 3 females, suffered from CI during HBOT, with the age from 51 to 76 yeas.METHODS: The background factors of 192 patients who HBOT METHODS and 6 cases with induced CI were analyzed.MAIN OUTCOME MEASURES: Symptoms, signs and skull CT or MRI.RESULTS: Data of 192 patients were dealt with intentionally and all were statistically analyzed without miss. ① The incidence of CI during HBOT was 0.3% (6/192). ② The risk factors of HBOT-induced CI included: age of ≥ 60 years, hypertension, hyperlipidemia, primary CI or cerebral hemorrhage, blood hyperviscosity and diabetes, and the incidence would greatly increased in those who has 4 or more than 4 risk factors, but seldom with less than 4 risk factors.CONCLUSION: The cluster level of risk factors was closely related with the incidence of HBOT-induced CI.

Objective To systematically evaluate the effectiveness and safety of glucoside tripterygium total (GTT) combined with antihistamine medicine for chronic idiopathic urticaria (CIU). Methods All randomized or semi-randomized controlled trials (RCTs or semi-RCTs) of GTT in treating CIU were collected from CNKI, VIP, WanFang Data, CBM, Embase, PubMed and Cochrane Library clinical controlled trials database. After two researchers conducted screening and data extraction independently, the quality of the included literature research was evaluated according to the risk of bias tool described in the Cochrane Handbook version 5.1.0, and then RevMan 5.3 was used to undertake Meta analysis. Results A total of 21 articles about RCTs and semi-RCTs were obtained, including 2194 patients. Meta analysis indicated that GTT combined with antihistamine medicine treatment showed higher effective rates compared with the control group [RR=1.33, 95%CI (1.26, 1.40), P<0.000 01], with obviously lower recurrence rate [RR=0.45, 95%CI (0.33, 0.62), P<0.000 01]. There was no statistical significance in adverse reactions. Conclusion GTT combined with antihistamine medicine for CIU has definite efficacy, and is relatively safe. Whether apply GTT combined with antihistamine medicine for CIU should be verified through randomized controlled trial with large-scale samples, multiple centers and high quality.
