BACKGROUND:There is controversial on which method is preferred for the treatment of humeral shaft fractures, plate or intramedul ary nail fixation? Some studies have compared the effect of those two methods, but the results are different. While the results of the systematic research and the Meta-analysis on the comparative studies is also different due to the differences in the number and the extraction of the researches.
OBJECTIVE:To systematical y evaluate the efficacy of plating versus intramedul ary nail fixation in the treatment of adult humeral shaft fracture.
METHODS:A computer-based retrieve was conducted in PubMed database, MEDLINE database, Cumulative Index to Nursing&Al ied Health Literature, Evidence-Based Medicine database, CBM database, Wanfang database and CNKI database for the randomized or quasi-randomized control ed trials on the comparison of plating and intramedul ary nail fixation in the treatment of adult humeral shaft fracture. The quality of these trials was critical y assessed according to Jadad. The effective data were extracted for Meta-analysis by Stata 12.0 software.
RESULTS AND CONCLUSION:Total y, 15 randomized or quasi-randomized control ed trials were col ected including four quasi-randomized control ed trials and 11 randomized control ed trials. The results showed that intramedul ary nail fixation may increase the risk of complications (odds ratio=0.37(0.19, 0.59), P=0.00). Bias Egger’s test of P=0.91 showed there was no significant publication bias. The risk of re-operation of intramedul ary nail fixation was increased (odds ratio=0.28(0.14, 0.57), P=0.00) with the Egger’s test of P=0.69. The incidence of shoulder impingement of intramedul ary nail fixation was significantly higher than that of pate fixation (odds ratio=0.13(0.05, 0.35), P=0.00), and there were no significant differences in postoperative infection, nonunion, implant failure, iatrogenic nerve palsy, operation time and bone union time between two methods. The results showed that compared with plate fixation, intramedul ary nail fixation may increase the incidence of shoulder impingement, complications and re-operation, while there were significant differences in postoperative infection, nonunion, implant failure, iatrogenic nerve palsy, operation time and bone union time between two methods.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.

Objective To evaluate the clinical effect in the treatment of the young patients(≤45 years old) with acute myocardial infarction(AMI)underwent emergent percutaneous transluminal coronary angioplasty(PTCA) combined with Lipo-PGE_1.Methods 39 patients with AMI(paroxysm within 12 hours),were underwent emergent PTCA(coronary stem performed in some patients),including 18 cases which were treated combined with Lipo-PGE_1 in the mean time.And the clinical efficacy and the results of short-period follow-up were recorded.Results The in- farctive vasculars were re-open in 37 patients(23 cares were routinely placed translunrinal srents),and the successful rate was 94.9 %.Those who also used Lipo-PGE_1 were re-open in 17 patients.The successful rate was 94.4 %,their ST segments on EKG 30 minutes after operations reduced significantly than that of patients who did not use Lipo- PGE_1,their cardial functions were also improved significantly 24 hours after operations and no side effects on blood pressure and heart rate were observed.Conclusion The emergent PTCA combined with Lipo-PGE_1 for acute my- ocardial infarction can protect the cardial function and show a better early therapy effect.

OBJECTIVETo detect the expression of human telomerase reverse transcriptase (hTERT) protein and mRNA in bile duct carcinomas and the adjacent tissues and to elucidate its role in bile duct carcinogenesis.

METHODSThe expression of hTERT protein and hTERT mRNA in the formalin-fixed paraffin-embedded specimens of 71 cases of bile duct cancers and 39 cases of adjacent tissues was detected by streptavidin-peroxidase immunostaining and in situ hybridization. The correlation was analysed statistically between the expression of hTERT protein and mRNA and clinicopathological parameters bile duct carcinomas.

RESULTSThe positive rate of hTERT protein expression and mRNA expression in malignant specimens was 78.9% (56/71) and 67.6% (48/71), while that in the adjacent tissues was 35.9% (14/39) and 23.1% (9/39), respectively. All the positive signals were found in the hyperplastic biliary epithelia. No significant correlation was established between hTERT expression and clinicopathological parameters.

CONCLUSIONhTERT gene transcription and protein expression is most likely involved in the proliferation and malignant transformation of bile epithelia and the malignant progression of bile duct carcinomas. The detection of hTERT expression may serve elucidating the carcinogenesis of bile duct.

OBJECTIVETo describe the temporal trends in the mortality rate of gastric cancer during the period of 1988 and 2010, and to predict the gastric cancer mortality between 2016 - 2020.

METHODSThe data of gastric cancer mortality in Linzhou city between 1988 and 2010 was extracted from the cancer registry, including a total of 11 714 cases, covering 22 447 073 person-years. The mortality rate of gastric cancer of each 5-year period was calculated by sub-site and gender. Age-standardized rate (ASR) was calculated using the Chinese standard population in 1982. Intrinsic estimator (IE) model was used to fit the mortality trend by sub-site and gender, and to predict the mortality of gastric cancer in Linzhou city between 2016 and 2020.

RESULTSFrom 1988 to 2010, the gastric cancer mortality in Linzhou city was 52.18/100 000 (11 714/22 447 073) with the ASR at 49.23/100 000; the mortality in male was 67.02/100 000 (7678/11 455 512) with ASR at 68.68/100 000 while the mortality in female was 36.72/100 000 (4036/10 991 561) with ASR at 32.12/100 000. The mortality of cardia carcinoma was 27.87/100 000 (6257/22 447 073) with the ASR at 26.37/100 000; while the mortality of non-cardia carcinoma was 24.31/100 000 (5457/22 447 073) with the ASR at 22.86/100 000. The ASR of gastric cancer during 1988 - 1990 was 63.37/100 000 (1653 cases) and decreased by 28.34%, to 45.41/100 000 (2622 cases) during 2006 - 2010. The IE model showed that the birth cohort effect decreased greatly. The mortality risk of cardia carcinoma in population born after 1950s, decreased significantly; and the mortality risk of non-cardia carcinoma in population born in 20 century continually decreased. The death of gastric cancer among the population over 30 years old was predicted to be 3626 cases, increasing by 40.60% compared with the number between 2006 and 2010 (2579 cases). Among them, the mortality of cardia carcinoma increased by 51.89% (predicted number between 2016 and 2020 was 2456 cases, and 1617 cases between 2006 and 2010), and the mortality of non-cardia carcinoma increased by 21.62% (predicted number between 2016 and 2020 was 1170 cases, and 962 cases between 2006 and 2010).

CONCLUSIONThe mortality rate of gastric cancer in Linzhou city showed a decreasing trend during the period of 1988-2010, being mainly attributed to the cohort effect. However, the mortality will still increase in the future, between 2016 and 2020.

OBJECTIVEAim of this study was to investigate functions of lower esophageal sphincter (LES) barrier and esophageal clearance in fasting and postprandial stages in gastroesophageal reflux disease (GERD).

METHODSEight patients with confirmed GERD and 8 healthy subjects (HS) were observed in the study. The esophageal pH and manometry were recorded simultaneously for 1 h during fasting and 2 h after a meal (1,675 kJ) using pneumohydrolic capillary perfusion system.

RESULTS(1) The esophageal pH monitoring showed that median of percentage of pH < 4 at postprandial in HS and patients with GERD was 0.45% and 11.2%, respectively (P < 0.05). (2) Pressure of lower esophageal sphincter (LESP) significantly decreased after a test meal in GERD (P < 0.001) and in HS (P < 0.001). (3) The amplitude of post-LES relaxation related to swallow (post-LESRA) in GERD was much lower than in HS either during fasting or postprandial stage (P < 0.05). (4) The tension of crural diaphragm at resting (Dia-A0) in GERD was lower than in HS during fasting and postprandial stage(P < 0.05). (5) The tension of crural diaphragm at deep inspiration (dia-AM) in GERD and HS increased 3 or 4 times at pressure at gastroesophageal junction (GEJ). (6) The peristaltic amplitude of the distal esophagus in GERD were much lower than that in HS in both pre- and postprandial periods.

CONCLUSIONS(1) Impaired clearance of Post-LESRA and esophageal body, function of diaphragmatic crural play an important role in development of GERD. (2) The tension of crural diaphragm at deep inspiration can increase the pressure at GEJ.

Poplar(Pupulus x Xiao zhannica, cv. "balizhuang-yang") transferred with mtl-D gene was used as an experimental material. Through tissue culture, aquaculture and pot culture transgenic poplars are tested with variant Nacl salt gradient. In it transgenic poplar raises its initial days for differentiation, differentiation rate, bud intensity, bud height and growth potential than control plant. At the same time, the transgenic poplar has higher rooting rate and more top roots, side roots and higher root length than control under the same salt stress. The result shows that the transgenic poplar has better tolerance ability than control plant in the salt 4@1000 contensity mediums.

Serological typing for HLA-A, -B has been used for a long time. Recently with the developing of molecular biology technologies, HLA-A, -B typing is now turning to genotyping methods. In our study, the capacity of PCR-SSP in solving problems in HLA-A, -B typing with serological methes was evaluated. With this aim the serological method was compared with PCR-SSP in 102 cord blood samples, and the results showed that 18.6% of 102 cord blood samples can't give a satisfactory detection, for 14 samples, give discrepant results with the 2 methods. It is mainly due to weak expression of HLA class I cord blood lymphocytes and the cross reaction of some antigens. About B 15 group, the further study was made, it was found that most of the B 15 splits is wrongly disassigned, especially among the B62-B75, B75/*1511(+)-B75/*1511(-), B46-*1511 antigens. It was concluded that DNA typing is more preferable than serological typing, about B 15 group, the subtyping or high resolution typing can be fulfilled at first in China.

In this research, the regulatory effects of T-lymphocytes on the expansion of hematopoietic cells in human bone marrow were studied. Anti-CD3 McAb and anti-CD8 McAb were used to eliminate the T-lymphocytes in bone marrow MNCs. Cell surface antigens were analysed by flow cytometry. Hematopoietic cells expanded with hematopoietic growth factors (HGFs) in a liquid culture system and the number of CD34(+) cell, CFU-GM and CFU-GEMM were determined. After cultured with HGFs for 20 days the total number of cells expanded by 75.8, 79.6, 77.4 and 67.0 folds respectively in three experimental groups (anti-CD3 McAb, anti-CD8 McAb and anti-CD3 + anti-CD8 McAb) and control group (MNC of bone marrow). The number of CFU-GM in the four groups were 173.67 +/- 18.90, 165.33 +/- 26.58, 170.33 +/- 21.50 and 79.67 +/- 8.33 respectively. The number of CFU-GEMM in the four groups were 431.33 +/- 34.56, 370.33 +/- 42.10, 386.67 +/- 10.02 and 177.67 +/- 26.86 respectively. There were significant differences in the number of CFU-GM and CFU-GEMM between experimental groups and control group. The results showed that the T-lymphocytes in bone marrow could inhibit the expansion of hematopoietic cells in vitro and the formation of CFU-GM and CFU-GEMM. The regulatory mechanism was to be explored.
