Adolescent scoliosis is spinal deformity happening in early adolescent or before bone mature.It can affect the body figure and appearance of children,threat the physical and mental health of the youth.Serious malformation even leads to heart and lung function failure.This paper summarizes the causes of disease incidence,the incidence situation in domestic and abroad,census method,the latest gene chip technique,the latest progress of treatment,and investigates the method of early prevention,early diagnosis,and early treatment.For younger children,non-surgical treatment such as brace could be used to avoid scoliosis aggravating.

Objective To investigate the changes of histamine receptors in bladder before and after the treatment by sodium hyaluronate in rats of interstial cystitis (IC). Methods Twenty IC model rats were randomly divided into experimental group and control group, with 10 for each group.The bladders in experimental group were filled with sodium hyaluronate, while the rats in control group were executed at once. The bladders were dyed with HE staining, special staining and immunohistochemistry staining to count the number of mononuclear cells and mast cells and observe the changes of histamine receptors. Results In experimental group,the counts of mononuclear cells and mast cells were 12.20±2.48 and 2.90±0.87 respectively;the numbers of average optical of histamine receptor H1, H2, H3, H4 were 0.015±0.007, 0.006±0.001, 0.007±0.004, 0.061±0.026 , respectively. In control group, the counts of mononuclear cells and mast cells were 23.90±3.07 and 7.08±1.23;the numbers of average optical of histamine receptor H1, H2, H3, H4 were 0.055±0.033, 0.031±0.023, 0.033±0.017, 0.091±0.059, respectively. The differences of mononuclear cells and mast cells were significant between the 2 groups(P＜0.01). The differences of average optical of histamine receptor H1, H2, H3 between the 2 group were significant (P＜0.05), while the difference of histamine receptor H4 was not significant(P＞0.05). Conclusion Histamine receptor H1, H2, H3 take part in the development of IC, the antagons may be used for the treament of IC.

OBJECTIVEWe used functional magnetic resonance imaging (fMRI) to explore the effects of noxious coldness and non-noxious warmth on the magnitude of cerebral cortex activation during intraoral stimulation with water.

METHODSSix male and female subjects were subjected to whole-brain fMRI during the phasic delivery of non-noxious hot (23 °C) and no- xious cold (4 °C) water intraoral stimulation. A block-design blood oxygenation level-dependent fMRI scan covering the entire brain was also carried out.

RESULTSThe activated cortical areas were as follows: left pre-/post-central gyrus, insula/operculum, anterior cingulate cortex (ACC), orbital frontal cortex (OFC), midbrain red nucleus, and thalamus. The activated cortical areas under cold condition were as follows: left occipital lobe, premotor cortex/Brodmann area (BA) 6, right motor language area BA44, lingual gyrus, parietal lobule (BA7, 40), and primary somatosensory cortex S I. Comparisons of the regional cerebral blood flow response magnitude were made among stereotactically concordant brain regions that showed significant responses under the two conditions of this study. Compared with non-noxious warmth, more regions were activated in noxious coldness, and the magnitude of activation in areas produced after non-noxious warm stimulation significantly increased. However, ACC only significantly increased the magnitude of activation under noxious coldness stimulation.

CONCLUSIONResults suggested that a similar network of regions was activated common to the perception of pain and no-pain produced by either non-noxious warmth or noxious coldness stimulation. Non-noxious warmth also activated more brain regions and significantly increased the response magnitude of cerebral-cortex activation compared with noxious coldness. Noxious coldness stimulation further significantly increased the magnitude of activation in ACC areas compared with noxious warmth.

Conclusion B.melitensis biovar 3 isolates showed polymorphism distribution in Guangdong province as in-dicated by MLVA typing analysis .Single-genotype isolates accounted for 62.8% of all studied strains.No predominant genotype was found among all isolates .

Objective To investigate the changes of 4 histamine receptors (H1R, H2R, H2R and H4 R)in interstitial cystitis on animal experimental models. Methods Thirty female SD rats (250-300 g) were randomly divided into 2 groups as follows: 20 in experimental group and 10 in control group. The experimental group was filled with protamine sulfate+ potassium chloride to create interstitial cystitis model, the control group was sacrificed directly. At the end of the experiment, the bladders of all these SD rats were studied by the immunohistochemistry staining and the value of their mean absorbance (-A) was calculated by IPP4.5 image analysis software. The SPSS 11.5 was used to analyze the differences between the groups. Results Four kinds of histamine receptors mainly expressed in the bladder epithelium. In the experimental group, the (-A) of H1 R was 0. 054±0.031, the of H2R was 0.032±0.021, the (-A) of H3R was 0.047±0.033 and the (-A) of H4R was 0. 149±0. 191,respectively. In the control group, the A of H1R was 0. 017±0. 011, the (-A) of H2R was 0. 018±0. 015, the (-A) of H3R was 0. 014±0. 011, the (-A) of H4R was 0. 060±0.039, respectively. In contrast,the A of H1 R, H2 R and H3R in experimental group was increased significantly(P＜0.05); there was no significant change in (-A) of H4R expression(P＞0.05). Conclusions H1, H2 and H3 receptors in rat model interstitial cystitis bladder epithelium have increased and it indicates H1 R, H2R and H3R may be related to interstitial cystitis. H3 R may be a new treatment target of interstitial cystitis.

Objective To investigate the effects of femoral nerve block combined with celecoxib on postoperative analgesia in elderly patients with hip fracture. Methods Two hundreds ASA -Ⅲ patients aged 65-89 yrweighing 35-90 kg undergoing hip fracture surgery were randomly divided into 4 groups ( n = 50 each):control group (group Ⅰ ), femoral nerve block group ( group Ⅱ ), celecoxib group (group Ⅲ ) and femoral nerve block +celecoxib group (group Ⅳ ). Operations were performed under combined spinal-epidural anesthesia. Groups Ⅲand Ⅳ were given oral celecoxib 400 mg at 1 h before operation, and 200 mg at 1 and 2 days after operation twice a day. Groups Ⅰ and Ⅲ received iv injection of sufentanil 0.06 μg/kg before the patients were placed in the position, while in groups Ⅱ and Ⅳ femoral nerve block was performed using a nerve stimulation with 20 ml of 0.5%ropivacaine and 10 min later the patients were placed in the position. All the patients received postoperative patient-controlled intravenous analgesia with sufentanil to maintain visual analogue scale score ≤ 3. The condition of satisfactory analgesia and sufentanil consumption within 24, 48 and 72 h were recorded. The coagulation function was measured on the day of admission to the hospital, at 1 day before operation and at 4 days after operation. Cardiac troponin Ⅰ (cTnI) concentrations were measured before operation, at the end of operation and at 1 day after operation. Postoperative complications was observed and recorded. Results Compared with group Ⅰ , the consumption of sufentanil was significantly reduced during each period in group Ⅳ ( P ＜ 0.01 ). Compared with group Ⅱ , the consumption of sufentanil was significantly reduced within 48 and 72 h after operation (P ＜ 0.05), while no significant change was found within 24 h after operation in group Ⅳ ( P ＞ 0.05). Compared with group Ⅲ , the consumption of sufentanil was significantly reduced within 24 h after operation ( P ＜ 0.05 ), while no significant change was found within 48 and 72 h in group Ⅳ ( P ＞ 0.05). The level of satisfactory analgesia was significantly higher in group Ⅳ than in the other three groups, and in groups Ⅱ and Ⅲ than in group Ⅰ ( P ＜ 0.05). The 4 groups were comparable with respect to the increased rate of cTnI concentrations at the end of operation and after operation, and perioperative blood coagulation. No postoperative complications were found in the 4 groups. Conclusion Femoral nerve block combined with celecoxib can reduce postoperative opioid consumption and enhance postoperative analgesia in elderly patients with hip fracture.

Objective: To examine the association between neonatal birth weight and maternal type 2 diabetes (T2DM), so as to provide insights into the formulation of the early T2DM prevention and improvements of maternal and children health. Methods: Single-nucleotide polymorphisms (SNPs) were collected from two genome-wide association studies (GWAS) that examined the association between neonatal birth weight and maternal T2DM. Inverse variance weighted method was employed for forward Mendelian randomization with 26 birth weight-associated SNPs as instrumental variables and maternal T2DM as the study outcome and for reverse Mendelian randomization with 18 maternal T2DM-associated SNPs as instrumental variables and maternal effects of neonatal birth weight as the study outcome. The heterogeneity was examined using Cochran's Q test, and the pleiotropy was evaluated using MR-Egger regression, while the robustness of the results was evaluated using leave-one-out test. Results: Cochran's Q test detected heterogeneity across two studies (P=0.019, 0.038), and random effect models were employed. Mendelian randomization showed that an increase in neonatal birth weight by per standard error (approximately 488 g) resulted a 29.9% reduction in the risk of maternal T2DM (OR=0.701, 95%CI: 0.547-0.899), and maternal T2DM increased the neonatal birth weight by 0.074 standard errors (OR=1.074, 95%CI: 1.043-1.106). No horizontal pleiotropy was seen for instrumental variables (P=0.241, 0.188). With each SNP excluded in turn, the results of Mendelian randomization study were robust. Conclusion There are bidirectional associations between neonatal birth weight and risk of maternal T2DM.
