Clinical Efficacy of Modified Xiao Chengqitang Combined with Acupoint Catgut Implantation in Treating Diet-induced Obesity Syndrome of Stomach Heat Dampness Obstruction / 中国实验方剂学杂志

Objective:To observe the clinical efficacy and safety of modified Xiao Chengqitang combined with acupoint catgut implantation in treating diet-induced obesity （DIO） syndrome of stomach heat dampness obstruction. Method:One hundred and seventy-two patients were randomly divided into control group（84 cases） and observation group（88 cases）. Both groups of patients received diet and exercise lifestyle adjustments， and acupoint catgut implantation was performed， 10 days for 1 time， 5 days intervals and then catgut implantation again， for a total of 6 times. Patients in observation group took modified Xiao Chengqitang granular powder， 10 g/time， with lukewarm boiled water in morning and evening. Patients in control group took modified Xiao Chengqitang granular powder simulant， 10 g/time， with lukewarm boiled water， 2 times/day. The treatment courses continued 4 months in two groups. Then the body mass index （BMI）， fat percentage （F%）， obesity， waist to hip ratio （WHR） were measured before and after treatment. Color Doppler ultrasonography was used to measure abdominal fat thickness， prehepatic fat thickness （AHF）， perirenal fat thickness （PRF）， and visceral fat index （UVI）. Fasting blood glucose （FBG）， triglyceride （TG）， total cholesterol （TC）， high-density lipoprotein-cholesterol （HDL-C）， low-density lipoprotein-cholesterol （LDL-C）， fasting insulin （FINS）， leptin （LP）， and adiponectin （APN） were detected before and after treatment， and the homeostasis model assessment of insulin resistance （HOMA-IR） index was calculated. In addition， safety evaluation was also conducted. Result:The BMI， F%， obesity degree and WHR in observation group were all lower than those in control group （<italic>P</italic><0.05 or <italic>P</italic><0.01）. Subcutaneous fat thickness， AHF， PRF and UVI in observation group were lower than those in control group （<italic>P</italic><0.01）. The TG， TC， LDL-C and FINS levels in observation group were lower than those in control group （<italic>P</italic><0.01）. The LP and HOMA-IR were also lower than those in control group （<italic>P</italic><0.01）， while the APN was higher than that in control group （<italic>P</italic><0.01）. The total effective rate in clinical application was （71/80） 88.75% in the observation group， higher than （57/75） 76.00% in the control group （<italic>χ</italic>²=4.374，<italic> P</italic><0.05）. Conclusion:Modified Xiao Chengqitang combined with acupoint catgut implantation in treating DIO syndrome of stomach heat dampness obstruction can adjust LP， APN and other factors， improve energy metabolism such as sugar and fat， and effectively control obesity with high safety， so it is worthy of clinical use.

Effect of Bio-Oss loading with rAAV-BMP7 on regeneration of bone defects around dental implant / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate in vivo gene delivery of Bio-Oss coated with adeno-associated virus-mediated human bone morphogenetic protein 7 (rAAV-BMP7/Bio-Oss) for bone regeneration around dental implants.</p><p><b>METHODS</b>In vitro rAAV-BMP7 were constructed and compounded with Bio-Oss. In 6 male New Zealand rabbits, two hydroxyapatite (HA) coated titanium dental implants were placed respectively to each animal in the bilateral tibia metaphysis. Before implantation, a standardized gap (8 mm in width, 4 mm in depth) was created between the implant surface and the surrounding bone walls. Rabbits were randomly divided into three groups (group A, B, C). Gaps of group A were filled with rAAV-BMP7/Bio-Oss (n = 4), gaps of group B were filled with Bio-Oss alone (n = 4), and gaps of group C were filled with nothing (n = 4). The rabbits were sacrificed at 4 and 8 weeks respectively, and the sclerous tissue slices obtained, then histology and histomorphometric analysis were conducted.</p><p><b>RESULTS</b>Histological and histomorphometric analysis revealed an enlarged bone-forming area in the bone defects of group A and B at 4 and 8 weeks after implantation. Greater bone-implant contact was achieved with rAAV-BMP7/Bio-Oss than with Bio-Oss alone and this difference was statistically significant (P < 0.05).</p><p><b>CONCLUSION</b>rAAV-BMP7/Bio-Oss can induce a stronger peri-implant bone reaction and larger new bone formation than Bio-Oss alone in the treatment of bone defects adjacent to titanium dental implants.</p>

Effects of transforming growth factor-beta1 gene therapy on bone rarefaction around endosseous implant / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the effects of transforming growth factor-beta1 (TGF-beta1) gene therapy on bone defect and bone rarefaction around endosseous implant.</p><p><b>METHODS</b>The primary cultured bone marrow derived stroma cells (BMSCs) was transfected by plasmid pCDNA3.1(+) -TGF-beta1, and was adhered with polylactic-co-glycolic acid (PLGA) for constructing TGF-beta1 gene-modified artificial bone. The model of rats with placed titanium implants in the proximal metaphyses of the tibiae after ovariectomy was made. The TGF-beta1 gene-modified artificial bone (experimental group), BMSCs-PLGA compound artificial bone (control group) and nothing (blank control group) were placed in the bone defect around implant. The tibiae were examined by decalcified sections with immunohistochemical method and histological analysis methods at intervals of 4 and 8 weeks after implant surgery in order to detect the expression of TGF-beta1 in new bone adjacent to the implant and the healing of the bone defect around the implant.</p><p><b>RESULTS</b>The expression level of TGF-beta1 of experimental group was higher than that of control group and blank control group at the 4th week. The histological analysis indicated that the gene-modified artificial bone had stronger osetogenic potential than others.</p><p><b>CONCLUSION</b>TGF-beta1 gene-modified artificial bone promotes the repair of the bone defect around titanium implants in osteoporotic rats.</p>

Detecting Hepatitis B Virus Deoxyribonucleic Acid Gene in Breast Milk by Nested Polymerase Chain Reaction / 实用儿科临床杂志

Objective With the method of detecting hepatitis B virus deoxyribonucleic acid(HBV-DNA) gene in breast milk,in ordered to diagnose whether there is HBV in breast milk in those mothers whose HBsAg are positive.Methods Collected breast milk from 187 mothers whose HBsAg were positive,and complified HBV-N gene in breast milk by Nested-Polymerase chain reaction (Nested-PCR).Results Nested-PCR could detect HBV-DNA in breast milk,and the positive rate was 3.2%.Conclusion The method of detecting HBV-N gene in breast milk by Nested-PCR can detect HBV-DNA in breast milk,and it can be an laboratory evidence for whether breast feeding or not.
