BACKGROUND: Allicin has been proved to influence the proliferation and apoptosis of LM-8 cells.OBJECTIVE: To study the effects of allicin on the expression of apoptosis protein Bcl-2 and Bax in C3H mouse osteosarcoma cell line LM-8, and the correlation of the morphological changes of LM-8 cells with the changes of Bcl-2 and Bax.DESIGN: Randomized grouping, non-blind, cell level, in vitro study.SETTING: The experiment was carded out from September 2006 to May 2007 at the Center Laboratory of Union Hospital,Tongji Medical College, Huazhong University of Science & Technology.MATERIALS: Osteosarcoma cell line LM-8 was purchased from the Animal Center of the Fourth Military Medical University of Chinese PLA. Allicin presented by Wuhan Huihai Co., was a sulphide isolated from garlic corn. Cell Counting Kit-8 (CCK-8) from Dojindo Laboratories; Bcl-2 antibody, Bax antibody and SP immunohistochemistry kit from Fuzhou Maixin Biotech Co.METHODS: LM-8 cells were cultured in RPMI 1640 culture medium, then cell climbing films were made, and SP immunocyte-histochemistry was used to detect the expression of Bcl-2 and Bax protein. Inverted microscope was performed to observe the morphologic changes of LM-8 cells before and after adding with 5.0, 10.0 and 15.0 mg/L allicin. Serial subcultivated LM-8 cells were adjusted to 7.5× 107 L-1 in concentration, added to 96-pore culture plate, and treated with allicin at a serial concentration of 1.0, 5.0, 10.0 and 15.0 mg/L. Additionally blank culture medium pores without cells and allicin and pores without allicin were taken as control groups. The 96-pore culture plate was maintained for 24, 48 and 72 hours, and then fetched. CCK-8 was added to determine the optical density value. The inhibition rate of LM-8 cell growth was also calculated. LM-8 cells were treated with different concentrations of allicin (5.0, 10.0 and 15.0 rag/L) for 24, 48 and72 hours, and then we carried out an apoptosis analysis by flow cytometry.MAIN OUTCOME MEASURES: Expression of Bcl-2 and Bax protein in LM-8 cells; cell morphous, cell proliferation,and cell apoptosis.RESULTS: ①Expression of Bcl-2 and Bax protein: Allicin could lower the expression of Bcl-2 protein and enhance the expression of Bax. The positive expression of Bcl-2, Bax and Bcl-2/Bax expression all showed significant differences compared with control group (P ＜ 0.01).②LM-8 cell morphous: LM-8 Cells treated with allicin presented typical apoptosis changes under microscope.③LM-8 cell proliferation: Allicin could inhibit the growth of osteosarcoma cell line LM-8, when concentration of allicin added from 1.0 mg/L to 15.0 mg/L, the inhibition rate of LM-8 cells at 72 hours increased from (23.87±3.26)% to (58.32±5.38)%, and 50% inhibiting concentration was 11.09 mg/L.④LM-8 cell apoptosis: After 72 hours with treatment of allicin of 5.0, 10.0 and 15.0 mg/L in concentration, apoptosis rate of LM-8 cells revealed a dose-dependent relationship (P ＜ 0.05).CONCLUSION: ①Allicin can inhibit the proliferation of LM-8 cells in a dose-time-dependent manner.②Allicin can induce the apoptosis of LM-8 cells in a dose-dependent manner.③Allicin can inhibit LM-8 cell proliferation and induce LM-8 cell apoptosis, which is related to down-regulate Bcl-2 protein expression and up-regulate Bax protein expression.

Objective To study the evaluation between the X-ray findings and ultrasound(US) manifestations of upper digestiveobstruction in infancy.Methods X-ray and US manifestations of 20 cases of infant with upper digestive obstruction proved by operationwere analysed respectively.Results In 20 cases,12 patients had pyloric stenosis,3 duodenal stresia,3 midgut malformation,2 hiatalhernia.Pyloric stenosis was diagnosed by X-ray in 11 cases,by US in 9,misdiagnosed by US in 1 case.Duodenal stresia was observed by X-ray and US in 2 cases separately,not observed by X-ray and US in 1 case separately.Midgut malformation was demonstrated by X-ray and US in 1 case separately,not demonstrated in 2 cases separately.Hiatal hernia was found by X-ray in 2 cases,misdiagnosed by US in 2 cases.Conclusion The two methods can't substitute with each other but complement.X-ray is better than US in the diagnosis of pyloric stenosis and hiatal hernia.US is better than X-ray in the diagnosis of midgut malformation.

Objective To investigate the value of detecting hepatitis B virus (HBV) YMDD variants by matrix-assisted laser de-sorption time of flight mass spectrometry (MALDI-TOF MS). Methods The assay is based on polymerase chain reaction (PCR) amplifica-tion and mass measurement of oligonucleotides containing sites of mutation of the YMDD motif. Result The MALDI-TOF MS-based genoty-ping assay was sufficiently sensitive to detect as few as 100 copies of HBV genome per milliliter of serum, and this method had superior spe-cificity for determining mixtures of wild-type and variant viruses. When sera of 40 patients were analyzed, the MALDI-TOF MS-based assay correctly identified known viral variants and additional viral quasi-species not detected by previous methods, as well as their'relative abun-dance. Conclusion The sensitivity, specificity and amenability to high-throughput analysis make MALDI-TOF MS-based assay suitable for mass screening of HBV infected patients who are receiving lamivudine.

The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dŭ", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).

OBJECTIVETo investigate the clinical efficacy of cannulated screw fixation with percutaneous Poking reduction for the treatment of Sanders II, III calcaneal fracture.

METHODSFrom January 2012 to January 2014, 19 patients with Sanders II, III calcaneal fracture were treated with cannulated screw fixation with percutaneous Poking reduction. There were 14 males and 5 females, ranging in age from 19 to 58 years old, with an average age of (38.3 +/- 4.1) years old. The changes of Bohler angle and Gissane angle were measured and compared preoperatively and postoperatively to observe the recovery of the articular surface. The Maryland Foot Score was used to evaluate operation outcomes.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 28 months with a mean of (22.3 +/- 5.3) months. The Bohler angle and Gissane angle were improved significantly after operation compared with those before operation (P < 0.05). The Maryland score was 83.2 +/- 8.4.

CONCLUSIONTreatment of calcaneal fractures with screw fixation with percutaneous Poking reduction has several advantages such as satisfactory outcome,less damage, fewer complications, quicker recovery, and shorter hospital stay,and it is one of the effective treatments for Sanders II and III calcaneal fractures.

Objective To discuss the clinical effect of transurethral cystitis glandularis electrocision combined with treating the diseases under bladder outlet in female.Methods One hundred and two female cases of cystitis glandularis who received transurethral electrical resection of the bladder mucosa combined with treating the diseases under bladder outlet were selected as experimental group,and another 78 female cases were selected as control group,who only received transurethral electrical resection of the bladder mucosa.The visual analogue score (VAS) was observed before and after a 12-week treatment,and the efficacy was evaluated by analysis of non parameter RIDIT.Results The operation time in experimental group and control group were 15-40 (26 ± 13) min and 8-19 (13 ± 5) min,respectively,and there was significant difference between two groups (P ＜ 0.05).Two groups cases urinated smoothly after the removal of catheter,without the occurrences of urinary fistula and incontinence.During the 12-weeks of follow-up,44 cases were cured,31 cases improved,15 cases were effective and 12 cases unimproved in experimental group; 26 cases were cured,21 cases improved,16 cases were effective and 15 cases unimproved in control group.There was significant difference between two groups (R =0.576,95％ CI0.519-0.633,P＜ 0.05).Conclusion Although the operation time is lengthened by transurethral cystitis glandularis electrocision combined with treating the diseases under bladder outlet in female,this method obviously improves curative effect.

Aim To observe the effects of activation of aldehyde dehydrogenase 2 ( ALDH2 ) by ethanol on testis injury of type 2 diabetic rats. Methods Type 2 diabetic rats model were established by high-fat diet combined with low-dose streptozotocin ( STZ ) injec-tions. After the success of modeling, the rats were ran-domly divided into 3 groups ( n =6 ): normal control group (NC), type 2 diabetes group (T2DM) and eth-anol+type 2 diabetes group (EtOH+T2DM). Rats of EtOH + T2DM were treated with low-dose ethanol, then rats of NC and T2 DM were given normal diet for 8 weeks. After 8 weeks, the levels of the fasting blood glucose ( FBG ) , glycosylated hemoglobin ( HbA1 c ) and testosterone were tested, and the ratio of testis weight to body weight ( TW/BW ) was calculated. Morphological changes of testis tissue were observed by optical microscope. The levels of ALDH2 mRNA and transforming growth factorβ1 ( TGF-β1 ) mRNA in tes-tis tissue were measured. The expression of TGF-β1 in testis tissue was observed by immunohistochemical stai-ning, then the positive rate of TGF-β1 was calculated. Results Compared with NC, the levels of FBG, HbA1 c and TW/BW increased significantly and the level of testosterone decreased significantly in T2DM. The morphological observation showed that some semi-niferous tubules atrophied, spermatogenic cells de-creased and arrangemented loosely, Leydig cells de-creased in testicular interstitial. The level of ALDH2 mRNA in testis tissue decreased significantly, and the level of TGF-β1 mRNA and the positive rate of TGF-β1 in testis tissue increased significantly. However, compared with T2DM, the levels of FBG, HbA1c and TW/BW decreased, and the level of testosterone in-creased and the damage of testis tissue was attenuated in EtOH+T2DM. The level of ALDH2 mRNA in testis tissue increased significantly, and the level TGF-β1 mRNA and the positive rate of TGF-β1 in testis tissue decreased significantly. Conclusion Activating AL-DH2 can protect testis in type 2 diabetic rats, which may be related to the downregulation of TGF-β1 ex-pression.
