OBJECTIVETo compare the effects on lumbar disc snake herniation between acupuncture in combination of snake moxibustion with simple acupuncture or snake moxibustion.

METHODSOne hundred and twenty cases of lumbar disc herniation patients were randomly divided into an acupuncture and snake moxibustion group (group A, 60 cases), a acupuncture control group (group B, 30 cases) and a snake moxibustion control group (group C, 30 cases). In group A, acupuncture was applied to Shenshu (BL 23), Dachangshu (BL 25) and tender points bilateral to the spine, once a day. Additionally, at the end of acupuncture on the 1st day of a week, snake moxibustion was applied for one time. In group B and group C, acupuncture or snake moxibustion was applied respectively.

RESULTSThe excellent rate was 95.0% (57/60) in group A, which was superior to that of 70.0% (21/30) in group B and 66.7% (20/30) in group C (both P < 0.05). JOA scores in each group after treatment increased apparently (all P < 0.01), of which, the scores in group A increased much more apparently as compared with those of the other two groups after treatment (both P < 0.01). The efficacy in group A was relevant obviously with the duration of sickness, the shorter the duration of sickness was, the higher the excellent rate would be. The age of patients in group A was relevant obviously with the efficacy, the younger patient was, the higher excellent rate would be.

CONCLUSIONThe efficiency on lumbar disc hernation treated with acupuncture and snake moxibustion is superior to that with either acupuncture or snake moxibustion.

OBJECTIVETo detect the effects of vasectomy on the growth and apoptosis of prostatic tissue cells.

METHODSForty-five SD rats were divided at random into three groups of fifteen each. Vasectomy (Vsm) model was established by ligating the bilateral vas deferens of the rats in Group A and testosterone propionate and normal saline were subcutaneously injected in those of Groups B and C, respectively. The area percentage of each part in the prostatic tissue was measured with computer-assisted image analysis system. The apoptotic rate was examined with TUNEL.

RESULTSThe ratio of stromal area to epithelial plus lumen area in the prostatic tissues in Groups A, B and C were (29.20 +/- 6.85), (39.77 +/- 7.58) and (48.90 +/- 6.49), respectively, and the differences were significant statistically (P all < 0.05). The apoptosis rates in Groups A, B and C were (6.39 +/- 0.84)%, (2.62 +/- 0.57)% and (4.58 +/- 0.93)%, respectively, significantly higher in Group A than in Groups B and C (P all < 0.05).

CONCLUSIONVasectomy may induce interstitium reduction and cell apoptosis in the prostatic tissues of rats, which may help prevent benign prostatic hyperplasia.

OBJECTIVETo explore the relationship between the expression of caspase-3 in testicular germ cells of rats with experimental left varicocele (ELV) and apoptosis of germ cells.

METHODSTwenty-four male SD rats were randomly divided into three groups with eight animals each: sham-operation group (SOG), 30-day post-operation group (PG1) and 60-day psot-operation group (PG2). ELV model was established by the partial ligation of the left renal vein. To detect apoptosis of germ cells and expression of caspase-3, TUNEL assay and immunohistochemistry (SABC) were used respectively.

RESULTSThe number of caspase-3 positive germ cells per tubular cross section in left and right testes of rats in SOG, PG1, PG2 were 0.1175 +/- 0.0129, 0.2463 +/- 0.0421, 0.2938 +/- 0.0511 and 0.1650 +/- 0.0192, 0.2538 +/- 0.0219, 0.2775 +/- 0.0343, respectively. Compared with SOG, the expression of caspase-3 in bilateral testes of rats in PG1 and PG2 were increased, and the differences were statistically significant(P = 0.0115 and P = 0.0144).

CONCLUSIONExpression of caspase-3 protein increased in germ cells of rats with ELV, which may be one of the molecular mechanisms related to excessive testicular germ cell apoptosis.

Objective: To explore the effect of improving these traits through art therapy group meetings as a form of psychological counseling, so as to promote mental wellness among this population. Methods: A total of 74 hearing impaired students from grades 3 to 9 were surveyed with the Children s Self concept Scale (PHCSS) and Social Adaptability Scale. Eight art therapy group meetings, as a form of psychological counseling, were then held. Results: Self consciousness among hearing impaired students aged 10-12 and 13-16 years old was significantly lower than the national norm ( t =-6.51, -8.50, P <0.01). The social adaptability level of this group was very poor(2.89±8.26), and a significant positive correlation was found between self awareness and social adaptability among hearing impaired students. Further, self awareness could predict the social adaptability of these students ( F = 9.04 , P <0.05). After group psychological counseling intervention, there was significant increases in self consciousness among students from grades 3 to 9, and significant increases were also found in the social adaptability of students in grades 3, 4, 5, 6 and 8 ( P <0.05). Conclusion Self awareness shows certain influence on the social adaptability level of hearing impaired students, and group psychological counseling can promote social adaptability by improving self awareness among this population.

Salvianolic acid B(Sal B) is the main water-soluble component of Salvia miltiorrhiza Bunge. Studies have found that Sal B has a good protective effect on blood vessels. Sal B can protect endothelial cells by anti-oxidative stress, inducing autophagy, inhibiting endoplasmic reticulum stress(ERS), inhibiting endothelial inflammation and adhesion molecule expression, inhibiting endothelial cell permeability, anti-thrombosis, and other ways. In addition, Sal B can alleviate endothelial cell damage caused by high glucose(HG). For vascular smooth muscle cell(VSMC), Sal B can reduce the synthesis and secretion of inflammatory factors by inhibiting cyclooxygenase. It can also play a vasodilatory role by inhibiting Ca~(2+) influx. In addition, Sal B can inhibit VSMC proliferation and migration, thereby alleviating vascular stenosis. Sal B also inhibits lipid deposition in the subendothelium, inhibits macrophage conversion to foam cells, and reduces macrophage apoptosis, thereby reducing the volume of subendothelial lipid plaques. For some atherosclerosis(AS) complications, such as peripheral artery disease(PAD), Sal B can promote angiogenesis, thereby improving ischemia. It should be pointed out that the conclusions obtained from different experiments are not completely consistent, which needs further research. In addition, previous pharmacokinetics showed that Sal B was poorly absorbed by oral administration, and it was unstable in the stomach, with a large first-pass effect in the liver. Sal B had fast distribution and metabolism in vivo and short drug action time. These affect the bioavailability and biological effects of Sal B, and the development of clinically valuable Sal B non-injectable delivery systems remains a great challenge.

Tetramethylpyrazine is the main component of Ligusticum chuanxiong. Studies have found that tetramethylpyrazine has a good protective effect against cardiovascular diseases. In the heart, tetramethylpyrazine can reduce myocardial ischemia/reperfusion injury by inhibiting oxidative stress, regulating autophagy, and inhibiting cardiomyocyte apoptosis. Tetramethylpyrazine can also reduce the damage of cardiomyocytes caused by inflammation, relieve the fibrosis and hypertrophy of cardiomyocytes in infarcted myocardium, and inhibit the expansion of the cardiac cavity after myocardial infarction. In addition, tetramethylpyrazine also has a protective effect on the improvement of familial dilated cardiomyopathy. Besides, the mechanisms of tetramethylpyrazine on blood vessels are more abundant. It can inhibit endothelial cell apoptosis by reducing oxidative stress, maintain vascular endothelial function and homeostasis by inhibiting inflammation and glycocalyx degradation, and protect vascular endothelial cells by reducing iron overload. Tetramethylpyrazine also has a certain inhibitory effect on thrombosis. It can play an anti-thrombotic effect by reducing inflammatory factors and adhesion molecules, inhibiting platelet aggregation, and suppressing the expression of fibrinogen and von Willebrand factor. In addition, tetramethylpyrazine can also reduce the level of blood lipid in apolipoprotein E-deficient mice, inhibit the subcutaneous deposition of lipids, inhibit the transformation of macrophages into foam cells, and inhibit the proliferation and migration of vascular smooth muscle cells, thereby reducing the formation of atherosclerotic plaque. In combination with network pharmacology, the protective mechanism of tetramethylpyrazine on the cardiovascular system may be mainly achieved through the regulation of phosphatidylinositol 3 kinase/protein kinase B(PI3K/Akt), hypoxia-inducible factor 1(HIF-1), and mitogen-activated protein kinase(MAPK) pathways. Tetramethylpyrazine hydrochloride and sodium chloride injection has been approved for clinical application, but some adverse reactions have been found in clinical application, which need to be paid attention to.

Objective To evaluate the effectiveness of radial extracorporeal shockwave therapy(rESWT) for the treatment of superior lateral brachial cutaneous nerve(SLBCN) compression syndrome.Methods A total of 40 patients with SLBCN compression syndrome who were treated in our department from March 2013 to October 2015 were equally randomized into two groups according to random number table:rESWT group(treated with rESWT for 1 cycle) and control group(treated with local hormone injection for 1 cycle). Visual analogue scale(VAS) and Constant-Murley scale(CMS) were applied to evaluate the shoulder joint function before treatment and 1 month and 1 year after treatment. Results The average CMS scores were(66.7±0.9) and(65.7±1.1)scores in rESWT group and control group,respectively,before treatment(t=0.67,P=0.510) and were(86.9±1.0) and(86.4±1.1)scores one month after treatment(t=0.35,P=0.730);it increased to(89.7±0.7) scores in rESWT group one year later,which was significantly higher than that in control group[(85.3±0.8)scores](t=3.56,P=0.002). The improvement rate was 95% in rESWT group and only 75% in control group. Before treatment,the median VAS score in rESWT group and control group were 5.00(5.00,6.00) and 5.00(4.00,5.75)scores(u=1.13,P=0.29);one month after treatment,the median VAS score in these two groups were 2(1.00,2.75) and 2.00(1.00,2.00)scores(u=0.04,P=0.85);one year later,it was 1.00(0.00,1.00) scores in rESWT group,significantly lower than that in [2.00(1.00,2.00)scores] control group(u=5.09,P=0.02). Conclusion Compared with local hormone injection,rESWT can remarkably alleviate pain and restore shoulder joint function in patients with SLBCN compression syndrome after one year of treatment.

To observe the effect of polydatin on proliferation and apoptosis of cervical cancer HeLa cells and explore its possible mechanism. The growth inhibitory effect was detected with MTT assay. After HeLa cells were treated with different concentrations (50, 100, 150 μmol•L⁻¹) of polydatin, MTT assay was used to detect the inhibitory effect of polydatin on proliferation of HeLa cells; Acridine orange/ethidium bromide staining was used for morphological changes in apoptotic HeLa cells； Annexin/propidium iodide staining was applied to detect HeLa cell apoptotic rate. In addition, flow cytometry was employed to analyze apoptosis and cell cycle distribution； RT-PCR and Western blot assay were used to detect PI3K, AKT, mTOR, and P70S6K mRNA and protein expression levels. The results showed that polydatin significantly inhibited HeLa cells proliferation in a dose-dependent manner. Polydatin can cause S phase arrest for HeLa cells, promote cell apoptosis and decrease the mRNA and protein expression levels of PI3K, AKT, mTOR and P70S6K. It indicated that polydatin could inhibit proliferation and induce apoptosis of cervical cancer HeLa cells, and the mechanism may be associated with inhibiting the PI3K/AKT/mTOR signaling pathway and suppressing downstream gene expression.
