OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.

METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.

RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.

CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

OBJECTIVE:To compare the quality control index between Jinzhen Suanzao teabag and decoction,and explore the alternative supplement of teabag to decoction. METHODS:The test sample solutions of Jinzhen Suanzao teabag and decoction were prepared by hot-maceration method and water-decoction method. The contents of water soluble extract and total flavonoids were de-termined and compared between 2 kinds of preparation. The leaching rates of teabag were investigated at different soak time(0,5, 10,15,20,25,30 min) to optimize soaking time. RESULTS:The average content of water soluble extract were 50.56% and 44.45%(P<0.05) respectively for the teabag and decoction. The total flavonoids content were 0.64 mg/g and 0.69 mg/g (P<0.05). The dissolution amount of teabag were increasing and leaching rate increased within first 20 min,and reached balance gradu-ally 25 min later. CONCLUSIONS:According to the convenience of use and results of each index,the difference in quality control index is not great between 2 kinds of preparation. Teabag can be as the supplement of decoction.

Objective To evaluate the surgical techniques and clinical applications of single-port transumlilical laparoscopic dismembered pyeloplasty for the treatment of ureteropelvic junction obstruction (UPJO). Methods From August 2009 to March 2010, 15 patients were treated with single-port transumbilical laparoscopic dismembered pyeloplasty. There were 12 males and 3 females,aged 12 to 55 years with an average age of 20 years, who were diagnosed by diuretic renography,IVU, and MRU et al. A single umbilical incision of 3. 5cm was made for single-port trocar and a flexible-tip 0°digital video-laparoscope was used in all cases. The procedures were performed according to the methods used in classical laparoscopic dismembered pyeloplasty with general instruments. ResultsAll operations were performed successfully without conversion to open surgery. The mean operative time was 90 (75-145) min, and the mean hospital stay length was 6 days. No organs injury occurred during operation, and no urine leakage was found afer operation. The symptoms of low back pain disappeared and hydronephrosis reduced apparently or dispeared without any anastomotic stenosis after follow-up of 4-6 months. Conclusions Single-port transumbilical laparoscopic dismembered pyeloplasty is feasible, effective and safe for the treatment of UPJO.

Using the chromosomal DNA of an ice nucleation active bacterium Erwinia ananas 110 as template, an ice nucleation active (ina) gene was amplified by PCR with Taq plusI DNA polymerase. After sequencing and compared with reported ina genes, the cloned gene was identified as a new ina gene and was registered in GenBank at the accession number of AF387802. The new ina gene, named as iceA, has 3921 bp for its coding region, which encodes 1306 amino acids consisting of repetitive segment (R-domain, 1104aa), which is flanked by N-and C-terminal sequences, with 161 aa and 41aa, respectively.

AIM: To clarify the effects of gastrin on t he expression of cyclooxygenase (COX) and several growth factors in rat gastric mu cosa. METHODS: Male Sprague Dawley rats were fasted for 24 hours and s ubcutaneously injected with saline or gastrin 17 at doses of 1 ?g/kg, 10 ?g/kg and 100 ?g/kg, respectively. The expression of COX-1, COX-2, heparin-binding e p idermal growth factor-like growth factor (HB-EGF) and hepatocyte growth factor ( HGF) in the gastric mucosa were examined using Western blotting and immunohistoc hemical staining. Effects of a potent gastrin receptor antagonist YM022 on the e xpression of COX-1, COX-2, HB-EGF and HGF in gastric mucosa were also evaluated. RESULTS: Gastrin dose-dependently increased the expression of C OX-2 and HB-EGF in rat gastric mucosa while the expression of COX-1 and HGF did not change significantly after treatment with gastrin. However, pretreatment wit h YM022 dose-dependently abolished the up-regulation of COX-2 and HB-EGF express ion induced by gastrin. CONCLUSIONS: This study demonstrates that gastrin up-regulates C OX-2 and HB-EGF expression in rat gastric mucosa, indicating that COX-2 and HB-E GF are involved in pathogenesis of the gastrin-related gastric mucosal hyperplas ia and carcinoma of stomach.

Objective To investigate the expression and clinical significance of peripheral blood CD4~+, CD25~+ and CD4~+CD25~+ T subpopulations in patients with systemic lupus erythematosis.Methods The per- centage and fluorescence intensities of peripheral blood CD4~+,CD25~+ and CD4~+CD25~+ subpopulations from 34 SLE and 18 normal controls were measured with flow cytometry assay,then the correlation with clincal data was analyzed.The CD25~+ cells were defined as the CD25~(high) cells if their fluorescence intensity was higher than 10. Results The percentage of CD4~+CD25~+,CD4~+CD25~(high) T lymphocytes in active SLE patients[(4.80?1.21)% and (0.25?0.10)%]was lower than that in normal controls[(8.92?3.21)% and(0.44?0.22)% and non-active SLE patients(11.28?2.09)% and(0.59?0.34)%](P＜0.05).However,as for the CD25~+ cells in the CD4~+ T cells,there was no difference between SLE patients and normal control group.Peripheral blood CD4~+CD25~+,CD4~+CD25~(high) cells in SLE were reversely correlated with SLEDAI(r=-0.74,P=0.004 and r=-0.614,P=0.026),but not with others such as complements,ANA titers etc.Peripheral blood CD4~+ and CD25~+ lymphocytes in active SLE pa- tients were also lower than those in normal controls[(23?7)vs(34?7)and(7.4?1.8)vs(13.9?3.4),P＜0.05]. CD25 fluorescence intensities were higher in the SLE patients those in the normal controls,but CD4 fluores- cence intensities were not.Conclusion CD4~+CD25~+ may play a role in the pathogenesis of SLE.

OBJECTIVETo establish osteoblast apoptosis model induced by gingipains, and to examine the expression of pro-apoptotic protein Bcl-2 interacting mediator (Bim), Bcl-2 associated X protein (Bax) and Bcl-2 antagonist/killer (Bak).

METHODSGingipain and gingipain acticity were extracted and measured. Mouse osteoblast cell line MC3T3-E1 cells were cultured in the presence of 0.453, 0.906, 1.812 U/L gingipains for 0, 16, 24 and 48 h. Apoptosis was examined by 4',6-diamidino-2-phenylindole (DAPI) staining or annexin V/propidine iodide (PI) staining.Protein expression of Bim, Bax and Bak was determined by Western blotting after osteoblasts were cultured with 1.812 U/L gingipain for 0, 4, 8, 16, 24 and 48 h. Osteoblasts were cultured with 1.812 U/L gingipain which had been inhibited with N-alpha-tosyl L-lysyl-chlorom ethylketone (TLCK). Western blotting was used to detect Bim expression and DAPI staining to measure apoptosis.

RESULTSArginine-specific proteinases (Rgp) activity was (18.11 ± 2.11) U/L and specific proteinases (Kgp) was (1.02 ± 0.25) U/L. Percentage of osteoblast apoptosis induced by 1.812 U/L gingipain rose to (6.31 ± 0.37)% after 16 h, and reached (11.20 ± 0.35)% at 24 h and (10.80 ± 0.46)% after 48 h with DAPI staining. Annexin V/PI staining supported the result from DAPI staining.Bim protein level increased during osteoblast apoptosis, the relative fold rose to (0.31 ± 0.03) after 4 h (about 2 fold compared to control), peaking at 24 h (0.57 ± 0.05, 3-4 fold compared to control). Proteinase inhibitor TLCK effectively blocked the activity of gingipain and inhibited up-regulation of Bim induced by gingipains from (0.58 ± 0.04) to (0.14 ± 0.03). The percentage of osteoblast apoptosis decreased from (11.20 ± 0.35)% to (4.31 ± 0.38)% in the presence of TLCK. Expression of Bax remained unchanged when cells were cultured with or without gingipains. Bak was under the detectable level in MC3T3-E1.

CONCLUSIONS1.812 U/L gingipains induced osteoblast apoptosis. Protein expression of Bim was up-regulated during cell apoptosis and was down-regulated when gingipain inhibited with TLCK, suggesting that Bim was involved in osteoblast apoptosis induced by gingipain. Inhibition of Bim protein expression protected osteoblast from apoptosis.

Objective To study the effect of systemic group music therapy (SGMT) on social living function and life quality in patients with schizophrenia. Methods By systematic sampling, 160 patients were divided into intervention group (80 patients) and control group (80 patients).Patients in the intervention group were treated by SGMT, and the control group was treated by general care.Comparison was made before intervention and 18 months after intervention on the following:scores of social living function as determined by the Activity of Daily Living Scale (ADL), Social Disability Screening Schedule (SDSS), and Social Maladjustment (SOC) scale.The WHO quality of Life-BREF scale was used to analyze score changes of patients′ life quality. Results ADL, SDSS and SOC scores of the patients in intervention group were significantly lower than those in control group (P values all 0.05).In comparison of the life quality scores, physical health, mental health and social relationship scores were higher in intervention group than those in control group(P values all < 0.05).There was no significant difference between two groups in environment scores(P>0.05). Conclusion Implementation of SGMT intervention can efficiently improve patients′ social living function and quality of life.

This study was aimed to investigate the therapeutic efficacy of rabbit anti-thymocyte globulin (r-ATG) combined with cyclosporine A (CsA) and to analyse the efficacy-related factors in children with aplastic anemia (AA). Twenty five AA children treated with r-ATG [3.5 mg/(kg·d)×5 days] combined with CsA were analyzed retrospectively. The lymphocyte subgroups, CD4(+)/CD8 ratio and expression of CD55, CD59 on surface of neutrophils and erythrocytes in peripheral blood were detected by direct immunofluorescence method and flow cytometry; the responsive time, effective rate, adverse effects and infections after immunosuppressive therapy (IST) were analyzed; the distribution of T-lymphocyte subgroups in IST-effective and IST-uneffective groups was compared, and therapeutic efficacy-related factors were evaluated. The results showed that the response to treatments was found in 21 out of 25 cases, the total responsive rate was 84.0%; the response time was 3 - 6 months, average of 4 months; the effective rates in month 3, 6, 9, 12 after treatment were 56.0%, 72.0%, 80.0% and 84.0% respectively. The AA children with age ≥ 5 years old, course of disease < 6 months and absolute neutrophil value ≥ 1.5 ×10(9)/L on 30 days after IST had good curative effect; the effective rate in AA children with age ≥ 5 years old, course of disease < 6 months, high or reverse ratio of CD4(+)/CD8(+) and absolute neutrophil value ≥ 1.5×10(9)/L after IST was higher than that in AA children with age < 5 years old, course of disease ≥ 6 months, normal ratio of CD4(+)/CD8(+) and absolute neutrophil value after IST < 1.5×10(9)/L (94.4% vs 57.1%, 90.4% vs 50.0%, 94.1% vs 62.5%, 94.1% vs 62.5%) (P < 0.05). The high effective rate was observed in AA children with decrease of CD55 and CD59 expression, but there was no significant difference (P > 0.05) as compared with normal expression of CD55, CD59. It is concluded that the treatment using r-ATG (3.5 mg/kg·d × 5 d) combined with CsA is a safe and effective for children with AA. Age, course of disease and absolute neutrophil value on 30 days after IST are the main factors affecting curative affect.
