Objective: To study the possible role and way of ALR in the immune regulation in vitro. Methods: The proliferation of spleen mononuclear cells of rat was detected with 3H-TdR method in vitro under the following different treatments:(1)the administration of the different concentration of rALR with 5 ?g/ml ConA at same time;(2)the addition of 30 ?g/ml ALR after 5 ?g/ml ConA pretreatment in 10 h and 32 h, respectively;(3)the addition of 5 ?g/ml ConA after 30 ?g/ml ALR pretreatment until 30 h. Cyclosporin A and the supernatant from cultures of yeast were used as positive and negative controls, respectively. The IL-2 levels in the supernatants from the mononuclear cells by various treatments were detected with RIA test kit. Results: rALR inhibited the proliferation and the production of IL-2 of the mononuclear cells from rat spleen stimulated by ConA dose-dependently. The mononuclear cell proliferations were still inhibited by 30 ?g/ml rALR after stimulated by ConA for 10 h or 32 h, but the pretreatment of 30 ?g/ml rALR for 30 h had no influence on the reactivity of mononuclear cell to ConA compared with control. Conclusion: rALR could inhibit in dose-dependent way the proliferation of mononuclear cells from rat spleen stimulated by ConA in vitro, but it couldn’t influence the rest mononuclear cells. This suggests that the rest mononuclear cells might not express the receptor of ALR.

Objective To investigate the clinical efficacy of ultrasound-guided double-tract percutaneous cholecystostomy combined with choledochoscopic gallbladder-preserving cholecystolithotomy for the elderly patients with acute calculous cholecystitis.Methods The clinical data of 35 elderly patients with cholecystolithiasis who were admitted to the General Hospital of Chengdu Military Command from January 2012 to December 2013 were retrospectively analyzed.All the 35 patients received ultrasound-guided double-tract percutaneous drainage,and then received choledochoscopic gallbladder-preserving cholecystolithotomy.The long-term oral use of anti-inflammatory and cholagogue medications after operation reduced recurrence of cholecystolithiasis.All the patients were followed up by telephone interview and outpatient examination till June 30,2014.Results All the 35 patients undergoing successfully the ultrasound-guided double-tract percutaneous cholecystostomy.Of the 35 patients,1 patient with the puncture bleeding was cured successfully by symptomatic treatment,1 patient was treated by cholecystectomy due to the unformed sinus tract under costal margin,and other 34 patients underwent successfully cholecystolithotomy.The follow-up was carried out for 4 to 24 months and 1 patient was diagnosed as with recurrence of cholecystolithiasic.Conclusion Ultrasound-guided double-tract percutaneous cholecystostomy combined with choledochoscopic gallbladder-preserving cholecystolithotomy for elderly patients with acute calculous cholecystitis is safe and feasible,with an advantage of promotional value.

Objective To investigate the effects of Kinesio taping on function of knees in girls. Methods 20 female students were tested the peak torque of centripedal and eccentric contraction of knee flexion and extension with Biodex isokinetic testing at 60°/s angular velocity, with Kinesio taping, placebo taping and without taping. Their amplitude root of mean square (RMS) of surface electromyography of vastus medialis (VM), rectus femoris (RM) and vastus lateralis (VL) were also recorded. Results For centripedal isokinetic contraction, the relative extensors peak torque was the most as Kinesio taping (P<0.01). There was no significant difference in relative flexor peak torque (P> 0.05). Standardized RMS of VM and VL were the least as Kinesio taping (P<0.01), but not significantly different of RF among all the conditions (P>0.05). For eccentric isokinetic contraction, the relative extensor peak torque of both extensors and flexors were the most as Kinesio taping (P<0.01), while the Standardized RMS of VM and VL were the least (P<0.01), but no significant difference was observed in RF (P> 0.05). Conclusion Kinesio taping may enhance the strength of centripedal, eccentric contractions of quadriceps and eccentric contractions of hamstring, and increase the muscle fibers recruitment of VM and VL.

Objective To set a rapid,simple gene diagnosis method for Down syndrome.Methods Three short tandem repeats(D21S11,D21S1270,D21S1437)loci in or near Down syndrome critical region(DSCR) were analyzed and detected by polymerase chain reaction and DNA quantitative analysis in 11 core ancestry.Results There were four types by DNA quantitative analysis to different individuals at a short tandem repeats(STR) locus.In type one,a homozygote of one allelic gene was detected.In type two,a normal heterozygote of two allelic genes was found,the content or two DNA electrophoresis bands was approximately 1∶1.In type three,a Down syndrome patient of two allelic genes was discovered.The quantity of two electrophoresis bands was nearly 2∶1.In type four,the patient showed three DNA electrophoresis bands which the content was approximately 1∶1∶1.Conclusion A rapid gene diagnosis and prenatal diagnosis method for Down syndrome can be used for quantitative analysis of STR polymorphism loci.

Objective To investigate the effects of mesenchymal stem cells (MSCs) transplantation combining with vascular endothelial growth factor (VEGF) gene therapy on myocardium rebuilding,angiogene- sis,and heart function improvement in rats with myocardial infarction.Methods SD rat MSCs were isola- ted,cultured in vitro,labeled with BrdU and transfected by Ad.VEGF gene.Four weeks after left anterior descending artery was ligated to created rat myocardial infarction,cardiac function was examined with echocar- diography,rats were randomly divided into four groups (n=10 in each group):GroupⅠ:MSCs/Ad.VEGF implantation;GroupⅡ:MSCs implantation;GroupⅢ:Ad.VEGF injection;GroupⅣ:Control.MSCs dif- ferentiation was observed 4 weeks after transplantation.Immunohistochemistry and angiogenesis were observed. Echocardiography was performed to detect the effects on heart function.Results MSCs labeled with BrdU could be identified in host hearts in groupⅠandⅡ,most of them positively stained with cTnT antibody. Echocardiography indicated that the improvement of the LVEF value in groupⅠwas more significant than that in the other three groups (P＜0.01,respectively).Some cells were incorporated into the coronary capillaries in the infarcted region.The capillary density in groupⅠwas higher than that in the other three groups (P＜0.01,respectively).Conclusion MSCs implantation combining with VEGF gene therapy can obviously re- pair damaged myocardium and enhance the angiogenesis in ischemic heart tissue.

Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) combined with abdominal muscle electrical stimulation on the pulmonary ventilation of patients with cervical spinal cord injury.Methods Twenty-five patients with cervical spinal cord injury were randomized into an experimental group (n =13) and a control group (n =12).The control group was given comprehensive rehabilitation treatment,including upper limb movements,standing training and training of respiratory function,while the experimental group was given repetitive transcranial magnetic stimulation and abdominal muscle electrical stimulation in addition to the comprehensive rehabilitation treatment.The patients' maximum lung capacity (VC),forced expiratory volume for 1 second (FEV1),peak expiratory flow rate (PEF) and tidal volume (VT) were measured at the outset and after 3 months of treatment.Results The lung function indexes increased in both groups after treatment,but each index improved significantly more in the experimental group,on average,than in the control group.Conclusion As a supplement to routine respiratory function training,repetitive transcranial magnetic stimulation combined with abdominal intermediate frequency electrical stimulation can improve the pulmonary ventilation function of patients with middle and lower cervical spinal cord injury.

Objective To study the protective effect and its mechanism of anti-tumor necrosis factor-?antibody (TNF-? Ab) on lung injury after cardiopulmanary bypass(CPB).Methods Twenty-eight healthy rabbits were selected and randomly divided into four groups:group Ⅰ only received open chest operation;groups Ⅱ-Ⅳ underwent CPB.In the group Ⅳ,rabbit TNF-? Ab (2 400 pg/kg) was dropped into the intracheal tube before operation and just after releasing the aortic clamp.Saline was given to the group Ⅲ in- stead.Blood neutrophils count,TNF-?,MDA from the right and left atrium in the four groups were determined perioperatively.Water volume,TNF-? mRNA,TNF-? protein,apoptosis and pathomorphological changes were measured in the lung tissues.Results TNF- ? Ab can restrain leukocyte accumulation,reduce releasing of TNF-? and MDA in the lung.It can also reduce the occurrence of apop- tosis and attenuate pathomorphological changes in the lung tissue.However,it cannot reduce the secretion of TNF-? at the transcrip- tion level and protein level.Conclusion Intratracheal TNF-? Ab administration has markedly protective effect on lung injury after CPB.

OBJECTIVETo investigate the effects of the plasma containing Qianlongtong Capsule (QLT)-containing plasma on the expression of the Smad4 gene in prostate stromal cells in vitro and provide some experimental evidence for the treatment of benign prostatic hyperplasia (BPH) with Chinese medicinal compound.

METHODSFifteen cases of BPH were equally randomized to three groups to be treated with QLT at a high dose (6 capsules once), a medium dose (3 capsules once), and a low dose (1.5 capsules once), tid, for 7 days consecutively. QLT-containing plasma was collected from the patients. Prostate stromal cells were identified by immunofluorescence when they became monolayered and cultured in the QLT-containing plasma for 24 hours, followed by detection of the expression of the Smad4 gene by real-time quantitative PCR and that of the Smad4 protein by Western blot.

RESULTSAfter treatment with the QLT-containing plasma, the expression of the Smad4 gene in the stromal cells was significantly increased in a dose-dependent manner as compared with the blank control and no-QLT groups (P < 0.01). The expression of the Smad4 protein was also markedly elevated after treatment. The differences were statistically significant between the blank control and medium-dose groups (P < 0.01), low-dose and medium-dose groups (P < 0.05), and high-dose and the other groups (P < 0.01), but not between the blank control and low-dose groups (P > 0.05).

CONCLUSIONQLT-containing plasma could inhibit the proliferation and improve the apoptotic index of prostate stromal cells in vitro, which was related to the elevation of the mRNA and protein expressions of Smad4.

OBJECTIVETo explore the effect of combination of Epimedii Folium and Ligustri Lucidi Fructus on osteoporosis rats induced by retinoic acid.

METHODSixty three-month-old male Wistar rats were randomly divided into the normal control group, the model group, the Epimedii Folium group, the Ligustri Lucidi Fructus group, the combination group of Epimedii Folium and Ligustri Lucidi Fructus and the raloxifene group. The osteoporosis model was established through oral administration with retinoic acid for two weeks. Meanwhile, all of treatment groups were administered with corresponding drugs for three weeks. The contents of serum calcium (Ca), phosphorus (P), alkaline phosphatase (AKP) and tartrate-resistant acid phosphatase (StrACP) were detected, and the pathomorphological changes of femurs were observed.

RESULTThe model control group showed much lower contents of serum Ca and P than the normal control group, but with significantly higher AKP and StrACP activity than the normal control group. The femoral head area showed reduced, narrow and sparse trabecular bones, with typical osteoporosis-like changes. Compared with the model control group, all of treated groups showed significant increase in Ca and P contents in serum, and down-regulate AKP and StrACP levels, while trabecular bones became more and wider, and densely interweaved as a reticular formation. Among them, the combination group showed the most significant effect.

CONCLUSIONEpimedii Folium and Ligustri Lucidi Fructus could effectively correct the abnormal bone metabolism and improve pathological conditions of bone tissues, so as to show the anti-osteoporosis effect. The combined application of the two drugs showed a better efficacy.
