[Effect of acupoint thread-embedding therapy on the sitting ability of ataxia children with cerebral palsy].

OBJECTIVE: To investigate the effective of acupoint thread-embedding therapy for ataxia children with cerebral palsy. METHODS: A total of 70 ataxia children with cerebral palsy and a Gross Motor Function Measure (GMFM, Dimension B) score of <35 were enrolled and randomly divided into thread-embedding group and control group, with 35 children in each group, and 2 children in the thread-embedding group were lost to follow-up. The children in the control group were given routine rehabilitation treatment, including physical therapy, spleen-strengthening, kidney-nourishing, and Governor Vessel-regulating massage, vibroacoustic therapy, and scalp acupuncture, and those in the thread-embedding group were given thread-embedding therapy at the acupoints of Jianyu (LI15), Jianliao (SJ14), Tianzong (SI11), Tianshu (ST25), and HuatuoJiaji points (C4, L1 and L4) in addition to the treatment in the control group, with 6-8 acupoints selected each time, once a week. Each course of treatment was 4 weeks, with an interval of one week between two courses of treatment, and the children were treated for 3 courses. Level of sitting scale (LSS), incurvation reflex, and GMFM score were recorded to evaluate the improvement in sitting ability and clinical outcome. RESULTS: Both groups had significant improvements in LSS, incurvation reflex, and GMFM (Dimension A and B) score after treatment (P<0.01), and the thread-embedding group had significantly greater improvements than the control group (P<0.01). The thread-embedding group had a significantly higher overall response rate than the control group (90.9% [30/33] vs 68.5% [24/35], P<0.01). CONCLUSION: In addition to routine rehabilitation treatment, acupoint thread-embedding therapy can effectively suppress primitive reflex in ataxia children with cerebral palsy and significantly promote their sitting ability, and therefore, it is an effective acupuncture treatment method for ataxia children with cerebral palsy.

Multi-analysis of chemical transformations of lignin macromolecules from waterlogged archaeological wood.

A large number of archaeological wooden building poles have been excavated from the Hai Menkou site (Yunnan province, China). Lignin can be transformed and altered accompanied with significant loss of carbohydrates during this process. Elucidation of chemical and structural transformations of lignin is of primary importance for understanding both the nature of degradation processes and the structure of waterlogged archaeological wood, and crucial for developing proper consolidation technology and restoring artifacts of historical and cultural value. In this study, state-of-the-art analytical techniques, including SEM, FT-IR, XRD, CP-MAS 13C NMR, 2D-HSQC NMR, 31P-NMR, CRM, GPC and TG analysis, were all employed to elucidate the structural characteristics of lignin in waterlogged and reference Pinus wood. The results interpreted by NMR analysis demonstrated the depolymerization of lignin via cleavage of ß-O-4, ß-5, -OCH3 and some LCC linkages, leading to a higher amount of free phenol OH groups in the lignin from the ancient waterlogged wood as compared to that of the reference wood. Microscopically, it was found that extensive degradation of carbohydrates in cell walls was mainly occurred in secondary cell walls, while the lignin concentrations were relatively increased in CCML and S regions in the plant cell wall of the ancient wood.

Effect of Compound Zhajin Granule on Toll-like Receptor 4 Signaling Pathway in Nonalcoholic Steatohepatitis Mice / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of Compound Zhajin Granule (CZG) on Toll-like re-ceptor 4 (TLR4) signaling pathway in high-fructose corn syrup induced NASH mice.</p><p><b>METHODS</b>Thirty 6-week-old male C3H mice were divided into the high fat and high fructose (HFHFr) group (n = 20) and the control group (n = 10) according to body weight. Mice in the HFHFr group ate high fat diet and drank 20% fructose water, while those in the control group ate common diet and drank common water. After 8 weeks mice in the HFHFr group were divided into two group according to body weight, the HFHFr group and the CZG group, 10 in each group. Mice in the CZG group were fed with high fat forage and 20% fructose water, and administered with 50 mL/kg 12. 8% CZG (prepared by hawthorn, Radix Curcumae, Alisma Orientale, Fritillaria Thunbergii, Silybum Marianum, peach seed in the ratio of 3:1.5:1.5:2:1.5:2:1) by gastrogavage. Mice in the HFHFr group were fed in the same way and daily administered with equal volume of distilled water by gastrogavage. Sixteen weeks later all mice were sacrificed. Body weight, liver wet weight, liver function, and lipid metabolism were detected. Pathological changes of liver tissues were assessed by HE staining, oil red O staining, and Masson staining. Expressions of TLR4, myeloid differentiation factor 88 (MyD88), tumor necrosis factor-alpha (TNF-α) were detected using immunohistochemical staining and real-time fluorescent quantitative PCR.</p><p><b>RESULTS</b>Body weight, alanine aminotransferase (ALT), aspartate aminotransferase (AST) were obviously lower in the CZG group than in the HFHFr group (P < 0.05); oil red O stained area and density were decreased more in the CZG group than in the control group. HE staining showed ballooning inflammation was reduced more in the CZG group than in the HFHFr group. Masson staining was negative. Positive rates of TLR4 and MyD88 and mRNA expressions were significantly lower in the CZG group than in the HFHFr group (all P < 0.05).</p><p><b>CONCLUSION</b>CZG could significantly inhibit TLR4 signaling pathway of liver in NASH mice.</p>

[Risk factors for interictal epileptiform discharges on electroencephalogram in children with spastic hemiplegic cerebral palsy].

OBJECTIVE: To investigate the clinical symptoms and features of interictal epileptiform discharges (IED) on electroencephalogram (EEG) in children with spastic hemiplegic cerebral palsy (CP) and to analyze the risk factors for IED. METHODS: Eighty-three children with spastic hemiplegic CP were recruited, and their clinical data, results of video-electroencephalogram, imaging findings, and cognitive levels were collected. The influencing factors for IED were determined by multiple logistic regression analysis. RESULTS: The incidence of epilepsy was 13% in children with spastic hemiplegic CP; 34% of these cases had IED. The incidence of epilepsy in children with IED (32%) was significantly higher than that in those without IED (4%) (P<0.01). The incidence of IED in children with complications and brain cortex impairment increased significantly (P<0.01). The incidence of IED varied significantly between patients with different cognitive levels (P<0.01). Brain cortex impairment (OR=11.521) and low cognitive level (OR=2.238)were risk factors for IED in children with spastic hemiplegic CP (P<0.05). CONCLUSIONS: Spastic hemiplegic CP is often found with IED on EEG, and the incidence of epilepsy is higher in children with IED than in those without IED. Brain cortex impairment and low cognitive level have predictive values for IED in children with spastic hemiplegic CP.

Genetic polymorphisms of CYP2D6*10 and the effectiveness of combined tamoxifen citrate and testosterone undecanoate treatment in infertile men with idiopathic oligozoospermia.

Tamoxifen citrate, as the first line of treatment for infertile men with idiopathic oligozoospermia, was proposed by the World Health Organization (WHO), and testosterone undecanoate has shown benefits in semen values. Our objective was to assess the effectiveness of treatment with tamoxifen citrate and testosterone undecanoate in infertile men with idiopathic oligozoospermia, and whether the results would be affected by polymorphisms of CYP2D6*10. A total of 230 infertile men and 147 controls were included in the study. Patients were treated with tamoxifen citrate and testosterone undecanoate. Sex hormone, sperm parameters, and incidence of spontaneous pregnancy were detected. There were no significant differences between the control and patient groups with respect to CYP2D6*10 genotype frequencies (P>0.05). The follicle-stimulation hormone (FSH), luteinizing hormone (LH), and testosterone (T) levels were raised, and sperm concentration and motility were increased at 3 months and became significant at 6 months, and they were higher in the wild-type allele (C/C) than in the heterozygous variant allele (C/T) or homozygous variant allele (T/T) subgroups (P<0.05). In addition, the percentage of normal morphology was raised at 6 months, and represented the highest percentage in the C/C subgroup (P<0.05). The incidence of spontaneous pregnancy in the C/C subgroup was higher than that in the C/T or T/T subgroups (P<0.01). This study showed that the CYP2D6*10 variant genotype demonstrated worse clinical effects in infertile men with idiopathic oligozoospermia.

Accuracy of Endorectal Endoscopic Ultrasound (EUS) for Locally Advanced Rectal Cancer (LARC) Restaging After Neoadjuvant Chemoradiotherapy (NAT): A Meta-Analysis.

BACKGROUND/AIMS: Endorectal endoscopic ultrasound (EUS) can provide accurate and reliable information for initial staging of locally advanced rectal cancer (LARC) in both the depth of rectal cancer penetration (T-stage) and regional lymph node involvement (N-stage). However, there is still no consensus about its accuracy in retagging LARC after neoadjuvant chemoradiotherapy (NAT). METHODOLOGY: In this study, we retrieved previous studies and performed a meta-analysis for assessing the accuracy of EUS for retagging of LARC after NAT. RESULTS: It was found the accuracy of EUS for T restaging of LARC was relatively low and over-staging was common, although the accuracy for assessing T3/4 was significantly higher than T0-T2 stage. The specificity of EUS for assessing N stage was relatively high, but the sensitivity was relatively low. CONCLUSIONS: Data obtained in this study confirmed the overall accuracy of EUS is not sufficient to serve as a basis for decisions on restaging Exploring the possible application of new techniques is necessary for better restaging.

[The study on the UV and fluorescence properties of PAMAM dendrimers].

From 0.5 to 5.0 generation PAMAM dendrimers were synthesized with ethylenediamine core by Michael addition reaction and aminolysis reaction two repeated steps. The structure of dendrimers were confirmed by FTIR 1H NMR 13C NMR MS and all of these measurements showed that they were successfully synthesized. Furthermore, The authors studied the UV and fluorescence properties of different generation dendrimers. Because of diffenent terminal groups, it was found that the whole generation and half generation show different ultraviolet absorption peaks and the intensity of ultraviolet absorption is closely related to the molecular skeleton. There is no traditional fluorescence emission groups, but PAMAM dendrimers show the peculiar phenomenon. In this paper we detailedly studied the factors which affect PAMAM dendrimers fluorescence properties.

The risk of pulmonary complication after surgery for gallstone disease.

OBJECTIVES: To identify the risk factors of postoperative pulmonary complications (PPC) after surgery for gallstone disease. METHODS: A total of 544 patients undergoing open surgery for gallstone disease were retrospectively studied. Univariate and multivariate logistic regression were used to analyze each factor. RESULTS: There were 24 factors relating to PPC in univariate logistic analysis. And multivariate logistic analysis identified 5 independent risk factors associated with PPC, including perioperative aerosol therapy (OR = 5.906), duration of postoperative antacids therapy (OR = 1.145), duration of operation (OR = 1.011), preoperative serum albumin (OR = 0.689), postoperative analgesia (OR = 0.059), Logistic regression equation for predicting the risk of PPC was P(1) = 1/[1 + e-(- 9.803 + 1.776 x A + 0.135 x B + 0.011 x C - 0.372 x D - 2.835 x E)]. CONCLUSION: Perioperative aerosol therapy, duration of postoperative antacids therapy, duration of operation, preoperative serum albumin and postoperative analgesia were independent risk factors associated with PPC in patients undergoing surgery for gallstone disease.
