ABSTRACT
The scientific basis of acupuncture on mesenchymal stem cells (MSCs) for treating ischemic stroke (IS) is discussed. MSCs transplantation has great potential for the treatment of tissue damage caused by early stage inflammatory cascade reactions of IS, but its actual transformation is limited by various factors. How to improve the homing efficiency of MSCs is the primary issue to enhance its efficacy. As such, the possible mechanisms of acupuncture and MSCs transplantation in inhibiting inflammatory cascade reactions induced by IS are explored by reviewing literature, and a hypothesis that acupuncture could promote the secretion of stromal cell-derived factor-1α (SDF-1α) from ischemic foci to regulate SDF-1α/CXC chemokine receptor 4 (CXCR4) axis, thereby improving the homing efficiency of MSCs transplantation, exerting its neuroprotective function, and improving the bed transformation ability, is proposed.

ABSTRACT
OBJECTIVE: To report a modified transvaginal non-mesh repair surgery based on "double hammock" pelvic floor support theory,and to observe the perioperative characteristics and short-term follow-up effect.METHODS: We collected 72 patients who underwent modified transvaginal non-mesh repair surgery from October 2017 to July 2018 in the First People's Hospital of Yunnan Province.Data of perioperative,3-month,6-month and 12 month follow-up were analyzed.RESULTS: The procedures were performed successfully in 72 patients,the average operation time was(119±31)min,and the mean blood loss was(47.75±30.55)mL.No traumatic compliacations were found during the operation.The objective response rate evaluated postoperatively by POP-Q stage in short-term follow-up were 100%,and no subjective symptoms of recurrence were observed.CONCLUSION: Modified vaginal non-mesh pelvic floor repair based on the "double-layer hammock" pelvic floor support theory has the advantages of simple surgical procedure, fewer complications and good effect in the short-term. Further observation is needed to determine its long-term effectiveness.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the differential effect of joint ultrasound on the syndrome differentiation of rheumatoid arthritis (RA) by observing the high frequency ultrasound performances among inactive stage and different syndromes in active stage.</p><p><b>METHODS</b>Totally 83 RA patients in the active stage were assigned to the dampness heat syndrome group (DHS, 59 cases)and the cold dampness syndrome group (CDS, 24 cases) according to Chinese medicine (CM) syndrome typing. Besides, 20 RA patients in the remission stage were recruited as the control group (abbreviated as the remission group). By using high frequency ultrasound and power Doppler ultrasound technology, a comparative observation of synovitis, tenosynovitis, synovial blood flow, and bone erosion in the 2nd-5th metacarpophalangeal (MCP) joints, proximal interphalangeal (PIP) joints, wrist joints, knee joints, the second and the fifth metatarsophalangeal (MTP) joints (a total of 24 joints) was performed in all patients. Correlation analyses were performed between the ultrasound performance, laboratory indices, and the disease activity. Ultrasound data of each RA patient were analyzed by their total scores. Χ2 test was used for enumeration data. The measurement data was expressed as x ± s. One-way ANOVA was used for data of normal distribution, while non- parametric test was used for data of non-normal distribution. Correlation analysis of two variables was performed for clinical indicators and ultrasound indicators. Its significance was detected using Pearson correlation.</p><p><b>RESULTS</b>Compared with the remission group, the severity degree of synovitis, tenosynovitis, synovial blood flow, and bone erosion significantly increased in the DHS group (P < 0.01). There was statistical difference in ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF (P < 0.05, P < 0.01). There was statistical difference in the severity degree of synovitis and synovial blood flow, and DAS28 score in the CDS group (P < 0.05). Compared with the CDS group, there was statistical difference in the four ultrasound indices (P < 0.05, P < 0.01), ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF in the DHS group (P < 0.05, P < 0.01). There was no statistical difference in G, IgG, IgA, or IgM among the three groups (P > 0.05). There existed positive correlation between ESR and the synovitis degree, synovial blood flow, and bone erosion in the DHS group (r = 0.444, 0.397, 0.486, P < 0.05).There existed positive correlation between ESR and the synovitis degree, bone erosion, and synovial blood flow in the DHS group (r = 0.378, 0.270, P < 0.05). There existed positive correlation between the DAS28 score and the synovitis degree and synovial blood flow in the DHS group (r = 0.304, 0.351, P < 0.05).</p><p><b>CONCLUSIONS</b>The inflammation degree was the most severe in RA patients of DHS. High frequency ultrasound could provide better evidence for Chinese medical syndrome differentiation of RA patients.</p>

<p><b>BACKGROUND</b>5α-Reductase inhibitors (5α-RI) act by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), thereby preventing DHT induced benign prostatic hyperplasia. The existing 5α-RIs can be classified into two types: competitive and noncompetitive. Currently, limited evidence is available concerning the effect differences between the two types of 5α-RI on androgens. The purpose of this study was to assess the effects of competitive and noncompetitive 5α-RIs on serum and intra-prostatic androgens in beagle dogs.</p><p><b>METHODS</b>Twenty beagles with spontaneous benign prostatic hyperplasia were randomly allocated into two groups: epristeride group (n = 10) in which beagles were treated with epristeride at 1 mg/kg once a day for 3 months, and finasteride group (n = 10) in which beagles were treated with finasteride at 1 mg/kg once a day for 3 months. The levels of intra-prostatic testosterone and DHT were measured before treatment and on day one after three months medication. Serum levels of testosterone and DHT were measured at the same time points. Changes in androgen levels before and after treatment were analyzed, and comparisons were made within each treatment group and between treatment groups.</p><p><b>RESULTS</b>After 3-month treatment, serum and intra-prostatic DHT levels all decreased significantly in both the epristeride and finasteride groups. The change of DHT in serum was significantly higher in the finasteride group (-14% and -43% in epristeride and finasteride groups respectively, with P < 0.001); however there was no significant difference in the changes of intra-prostatic DHT between the two groups (-47% and -51% in epristeride and finasteride groups, respectively, P = 0.304). The decreases in DHT levels were accompanied by reciprocal increases in serum and intra-prostatic testosterone levels. Changes of testosterone were significantly higher in finasteride group both in serum (20% and 42% in epristeride and finasteride groups, respectively, P < 0.001) and in prostate tissue (18% and 29% in epristeride and finasteride groups, respectively, P = 0.004).</p><p><b>CONCLUSIONS</b>Two types of 5α-RI have similar effects in reducing DHT in prostate tissue in beagles. Competitive 5α-RI may reduce serum DHT to a greater scale, and significantly increase testosterone in beagle serum and prostate.</p>

Differences in design and implementation of clinical research on hypertension treatment with acupuncture and moxibustion were analyzed in this article so as to provide experiences to the design of clinical research on its treatment. Through document retrieval, it can be acquired that results of high quality clinical researches on treatment of hypertension with acupuncture and moxibustion have already been published. However, limitations in terms of sample size calculation, stochastic method, implementation of the blind method, selection of the control group and report on implementation process still existed in domestic documents. Therefore, high quality design proposals which not only in compliance with the features of acupuncture-moxibustion, but also accepted by modern medicine should be established with the combination of the advantages of acupuncture-moxibustion and clinical features of the disease. Moreover, standardizations on measuring the blood pressure, sample size calculation, selection of the control measurements, stochastic method and implementation of the blind methods should be established as well.

Conventional randomized controlled trial is considered as the gold standard of clinical trials in evalua ting pharmacologic effectiveness. Whereas, it still has some faults in the non-pharmacy interventions, such as surgery, acupuncture, massage, etc. Expertise-based randomized controlled trial makes up for some deficiencies of conventional randomized controlled trial, which has made better developments in the field of surgery, however, there is no any relevant retrieval literature found in the acupuncture field. It is feasible and practical of the expertise-based randomized controlled trial to be applied and promoted in the acupuncture-moxibustion clinical research for a further degree. Expertise-based randomized controlled trials might become the trend of acupuncture-moxibustion clinical stu dies in the future.

<p><b>BACKGROUND</b>The primary objectives of the treatment for the lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) are to produce rapid, sustained, and safe improvements in the symptoms that affect the quality of life in the majority of men over 50. In this study, we evaluated the efficacy and safety of the combined therapy with terazosin (apha1-adrenergic receptor antagonist) and tolterodine (anticholinergic agent) for LUTS associated with BPH.</p><p><b>METHODS</b>This combination study included 69 patients diagnosed with LUTS associated with BPH based on the International Prostate Symptom Scores (IPSS), urinary flow rate, prostate volume, urinary residual, and their serum prostate-specific antigen levels. Initially, 191 patients were treated with terazosin 2 mg once daily for one week. Those patients with continued LUTS after the initial treatment were allocated randomly into two groups: terazosin group (n = 36) in which patients were treated with terazosin 2 mg once daily for six weeks, and combination group (n = 33) in which patients were treated with both terazosin 2 mg once daily and tolterodine 2 mg twice daily for 6 weeks.</p><p><b>RESULTS</b>The IPSS were significantly improved in both groups after treatment, and the reduction of IPSS in the combination group was significantly greater than that in the terazosin group (P < 0.01). A decrease in urgency, frequency and nocturia were the main contributory factors causing the reduction of IPSS in the combination group. The differences about the peak urinary flow rate and the residual urine from the baseline values were noted in both groups after treatment, but were not significant between the two groups. The incidence of adverse effects in the combination group was higher than that in the terazosin group. As expected the most common adverse effect was mouth dryness which was associated with anticholinergic drugs such as tolterodine.</p><p><b>CONCLUSIONS</b>Patients with LUTS associated BPH appear the improved IPSS after combined therapy with terazosin and tolterodine. This study, although short term and limited numbers of patients, provides evidence that the combined therapy with terazosin plus tolterodine is a good approach for meeting the objectives of rapid, sustained, and safe improvements in the LUTS associated with BPH. And the profile of patients in this study might be used as the indication of such combined therapy for LUTS associated with BPH without urodynamic evaluation.</p>

In order to provide a complete picture of pathogenesis in cerebral ischemia, cerebral cortex in MCAO rats were analysed for alteration in their proteomes. Comparative proteome analysis was used to compare signal corresponding to individual cerebral cortex proteins on a two-dimensional gel between MCAO rats and the normal control (NC) group. After sample preparation, two-dimensional electroghoresis separated proteins were stained with Commassie Brilliant Blue. The image data were analyzed on a Dell computer using Image Master v 3.01 software. In cerebral cortex, 30 proteins were differentially expressed in MCAO rats compared with NC. There were 11 spots significantly increased, 15 spots significantly decreased and Adenylate kinase isoenzyme 1 was detected only in NC group, biliverdin reductase B, small inducible cytokine A4 [Precursor] only in MCAO group. Peroxiredoxin 2 divided into two points in MCAO6h group. In the end, this approach may lay a foundation for the further investigation of pathogenic mechanisms in cerebral ischmic injury.
