Objective: To observe the clinical efficacy of Zhi Shen Tiao Sui (regulating the mind and marrow) needling in treating depression after ischemic stroke. Methods: A total of 145 patients with depression after ischemic stroke were recruited between January 2016 and January 2018 and divided into two groups using random number table method, with 72 cases in the control group and 73 cases in the observation group. The control group received conventional treatment for ischemic stroke and medication, while the observation group was given additional Zhi Shen Tiao Sui acupuncture. The two groups were treated for 4 successive weeks. Clinical efficacy was analyzed after treatment. The neurological function pertinent scores [Hamilton depression scale (HAMD), clinical neurological deficit score (CNDS), activities of daily living (ADL), Fugl-Meyer assessment scale (FMA) and Barthel index (BI) scores], as well as the levels of cortisol (CORT) and adrenocorticotropic hormone (ACTH) were recorded in the two groups. Adverse reactions that occurred during treatment were also observed. Results: The clinical total effective rate was 82.2％ in the observation group, significantly higher than 66.7％ in the control group (P<0.05). After treatment, the HAMD and CNDS scores were markedly reduced in both groups (all P<0.05), and the ADL, FMA and BI scores were markedly increased (all P<0.05). The HAMD and CNDS scores were significantly lower in the observation group than in the control group after treatment (both P<0.05), and the ADL, FMA and BI scores were significantly higher in the observation group than in the control group (all P<0.05). The levels of CORT and ACTH declined significantly after treatment in the two groups (all P<0.05), and were markedly lower in the observation group than in the control group (both P<0.05). The adverse reaction rate was 2.7％ in the observation group, versus 4.2％ in the control group, and the between-group difference was statistically insignificant (P>0.05). Conclusion: Compared with sole use of Western medication, medication combined with Zhi Shen Tiao Sui acupuncture can promote the recovery of neurological function, down-regulate the levels of CORT and ACTH and enhance the clinical efficacy in treating patients with depression after ischemic stroke, with a relatively high safety rating.

Objective To investigate the effect of repetitive transcranial magnetic stimulation(rTMS)on the spinal segmental excitability after spinal cord injury in adult rats.MethodsT 10 spinal cord injury models were made with weight-drop method.8 weeks later,rTMS were applied to the experimental group at 0.5 Hz suprathreshold stimulation,500 pulses daily for 4 weeks.Spinal cord injury rats without stimulation and normal rats were used as controls.At different time points,electronic evoked F-wave were measured.The ratio of F-wave amplitude to M-wave amplitude(F/M)were compared among these groups.Immunohistochemistry was used to detect the expression of 5-hydroxytryptamine(5-HT)in the rostral and caudal lesion segments.ResultsThe ratio of F/M increased significantly(P<0.01)8 weeks after spinal cord injury compared with baseline ratio and regressed significantly(P<0.01)after 4 weeks of rTMS.Expression of 5-HT in grey matter around lesion was decreased after spinal cord injury and increased significantly(P<0.01)both in the rostral and caudal lesion segments in rTMS treatment group.ConclusionThe increased spinal segmental excitability after spinal cord injury can be regressed by rTMS,which may be resulted in increased expression of 5-HT.

Objective To explore the effect of repetitive transcranial magnetic stimulation(rTMS)on spinal cord injured rats.Methods Weight-drop spinal cord injury model was made at thoracic 10 segments with NYU impactor device.Stimulated group received daily superthreshold rTMS continued for 4 weeks.BBB locomotor scores were recorded weekly.Growth associated protein 43(GAP43)and 5-hydroxytryptamine(5-HT)were detected with immunofluorescence staining in the area of rostral and caudal to the lesion.Results The BBB scores in stimulation group improved compared with that in the control(P<0.01).GAP43 and 5-HT markers increased in the stimulation group(P<0.01),and they increased in the rostral than in the caudal areas(P<0.01).Conclusion rTMS can improve the locomotor function of incomplete spinal cord injury rats,which may result from the increase of expression of GAP43 and 5-HT.

Methods The data of 15 cases with gastroduodenal obstruction including 9 cases of carcinoma of head of pancreas and 6 cases of carcinoma of stomach were analyzed retrospectively. The operative procedures of the stent implanted and the tors accepted more radiation dose because the manipulation was under the fluoroscopy in a short distance and with a full field of view. sions, the postoperative eating habit and the development turnover of disease. The main death reasons were tumor transfer and sys-tem exhaustion. Conclusion To pay close attention to the details and main points of operative procedure is the key point to implant stent successfully for malignant gastroduodenal obstruction. The determinative factor to influence the curative effect is the develop-ment turnover of tumor.

OBJECTIVETo investigate the expression and significance of CD151 in pituitary adenomas.

METHODSThirty-six pituitary adenomas were collected immediately after surgery together with five normal pituitary tissue. Real time-PCR, Western blot and immunohistochemistry analysis were performed to detect the expression of CD151 mRNA and protein in thirty-six pituitary adenomases and five normal pituitary tissues.

RESULTSThe expression of CD151 in all pituitary adenomases was observed to be significantly higher than that in normal pituitary tissues by Western blot, real time PCR, and immunohistochemistry analysis (P < 0.01). The expression levels of protein and mRNA in invasive pituitary adenomas were much higher than those in non-invasive pituitary adenomas (P < 0.01).

CONCLUSIONThe results suggested that the expression of CD151 was closely correlated with malignant degree of pituitary adenomas, which indicated the expression of CD151 was intimately correlated with occurrence and development of pituitary adenomas. Detecting CD151 might be a vital index to predict prognosis of pituitary adenomas.

OBJECTIVETo explore activity laws of mitochondrial complex II in patients of deficiency-cold syndrome (DCS) and deficiency-heat syndrome (DHS) under various ambient temperatures.

METHODSSubjects were recruited by questionnaire and expert diagnosis from grade 1 - 3 undergraduates at Henan College of Traditional Chinese Medicine in November 2012, and assigned to a normal control group, the DCS group, and the DHS group, 20 in each group. Their venous blood samples were collected at two different temperature conditions. Activities of mitochondrial complex II were measured by spectrophotometry.

RESULTS(1) Comparison of mitochondrial complex It under various ambient temperatures: Compared with room temperature in the same group, activity values were all increased in the normal control group at cold temperature with significant difference (P <0.05), but there was no significant difference in the DCS group and the DHS group (P >0. 05). Compared with the normal control group, activity values of complex H were reduced in the DCS group at cold and room temperatures with significant difference (P <0.05). Compared with the DCS group, activity values of complex It were increased in the DHS group with significant difference (P <0. 05). (2) Changes of adjustment rates: Compared with room temperature, the adjustment rate all rose at cold temperature in the normal control group and the DHS group with significant difference (P <0.05), but with no significant difference found in the DCS group (P >0. 05). Compared with the normal control group at the same temperature, the adjustment rate in the DHS group and the DCS group was all reduced at cold and room temperatures with significant difference (P <0. 05). There were no significant difference in the adjustment rate between the DHS group and the DCS group (P > 0. 05).

CONCLUSIONSEnvironment temperature can affect the activity of mitochondrial complex II with different influence degrees on different syndrome types of people, but its change trend are basically identical.

Hot-melt extrusion was applied to prepare mesoporous silica/ethylcellulose mini-matrix for sustained release, and fenofibrate was used as a model drug, ethylcellulose and xanthan gum were chosen as sustained-release agent and releasing moderator, respectively. This novel matrix obtained the controlled release ability by combining mesoporous silica drug delivery system and hot-melt extrusion technology. And mesoporous silica particle (SBA-15) was chosen as drug carrier to increase the dissolution rate of fenofibrate in this martix. Scanning electron microscope, transmission electron microscope, small angle X-ray powder diffraction and N2 adsorption-desorption were introduced to determine the particle morphology, particle size and pore structure of the synthesized SBA-15. The results showed that SBA-15 had a very high Brunauer-Emmett-Teller specific surface area, a narrow pore size distribution, large pore volume and a ordered two-dimensional hexagonal structure of p6mm symmetry. Differential scanning calorimetry and X-ray powder diffraction results demonstrated that fenofibrate dispersed in an amorphous state inside the pores of the mesoporous silica which contributed to the improvement in the dissolution rate. The drug release of mini-matrices was influenced by ethylcellulose viscosity grades and xanthan gum concentration, which increased with the increasing of xanthan gum concentration and decreasing of ethylcellulose viscosity. Mini-matrix containing 22% xanthan gum exhibited a good sustained release performance, and the drug release behavior followed the first-order kinetics.

Objective To assess the applicability of the Modification of Diet in Renal Disease (MDRD)formula to kidney function impaired Chinese diabetic patients.Methods Glomerular filtration rates(GFRs)in 463 Chinese diabetic patients(219 female,244 male,aged 14 to 88)were estimated by measuring ~(99m)Tc-DTPA clearance and with equations based on serum creatinine(Scr)and cystatin C(Cys C)concentrations.GFRs derived from various equations were compared with the ~(99m)Tc-DTPA clearance GFRs and their relative accuracies were assessed with ROC analysis.All the Scr measurements were performed with both the Roche enzymatic assay and the Beckman LX20 kinetic alkaline picrate assay,and Cys C with immunonephelometric and immunoturbidimetric assays.Results The reciprocals of Cys C and Scr were linearly correlated with ~(99m)Tc-DTPA clearance GFRs(r=0.830 and 0.690,repectively).The correlation of GFR with Scr could be expressed by an adjusted MDRD equation:GFR [ ml?(min?1.73 m~2)~(-1)]=175?(Scr)~(-1.154)?(age)~(-0.203)?0.742(female)?0.827,where 0.827 was a coefficient for Chinese.The adjusted equation showed a better accuracy than the MDRD equation(areas under the ROC curve 0.818 vs 0.644).The adjusted equation was also more accurate than equations obtained in previous Chinese studies.GFRs were also estimated by using Cys(in mg/L)with the following equation:GFR [ ml?(min?1.73 m~2)~(-1)] = 63.24?(Cys C)~(-0.3378).The accuracy of the Cys equation was similar to the Scr equation,or better in patients aged 60 and above.The Roche enzymatic results which were traceable to the isotope dilution mass spectrometry(IDMS)methods were significantly lower than Beckman LX20 results,but the results were closely correlated with each other(Y = 0.94X-0.02).When non-traceable Scr results were used,the coefficient needed to be adjusted.Conclusions GFRs can be estimated with equations based on either Scr or Cys C.GFR estimation should use standardized Scr results and take into account ethnic effects.
