Research on syndrome distribution features, etiologies, and pathogeneses of Japanese encephalitis / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore Chinese medical syndrome distribution features of Japanese encephalitis (JE), and to analyze its correlation between syndromes and features of etiologies and pathogeneses.</p><p><b>METHODS</b>Recruited were 277 patients with confirmative diagnosis of JE from Wuhan Medical Treatment Center, Children's Hospital Affiliated to Chongqing Medical University, Fifth People's Hospital of Guiyang City, Hangzhou Sixth People's Hospital, and Chengdu Hospital of Infectious Diseases between July to September 2012. Chinese medical syndrome distribution features were summarized from their general materials and detailed records of clinical data, including medical history, symptoms and signs, tongue fur, and pulse figures.The frequency of symptoms and signs was calculated according to mild, ordinary, severe, extreme severe degrees. The distribution of Chinese medical syndromes was summarized. And its correlation between syndromes and features of etiologies and pathogeneses were analyzed.</p><p><b>RESULTS</b>After clustering analysis, Chinese medical syndromes of JE could be categorized as four groups: toxicity accumulation in Fei and Wei syndrome (TAFWS), brain collateral impaired by poison syndrome (BCIPS), depression of toxicity in the pericardium syndrome (DTPS), exhaustion of yin and yang syndrome (EYYS). BCIPS and DTPS were dominated, accounting for 74.0% (205 cases). The main causes covered evil of summer heat [accounting for 92.42% (256/277 cases)], heat [accounting for 87.73% (243/277 cases)], and toxin [accounting for 99.64% (276/277 cases)].</p><p><b>CONCLUSIONS</b>The four Chinese medical syndrome types of JE met Chinese medical clinical features of encephalitis. It is induced by infestation of dampness-heat, resulting in toxicity accumulation in Fei and Wei, brain collateral impaired by poison, depression of toxicity in the pericardium. Yin fluid and blood is exhausted as time goes by. Qi and yin are impaired to form intermingled deficiency and excess, and finally causing exhaustion of yin and yang.</p>

Study on quality of life of asymptomatic HIV infected persons with traditional Chinese medicine / 中国中药杂志

<p><b>OBJECTIVE</b>Study on quality of life of asymptomatic HIV infected persons with traditional Chinese medical, which can provide the clinical basis for improving the quality of life.</p><p><b>METHOD</b>This study applied a randomized, double-blind, and placeb-parallel control designed method to select 1 200 persons in the asymptomatic period of HIV infection as the subjects. The subjects were randomly divided into the treatment group and the control group at the ratio of about 2:1. According to the results of monthly differential diagnosis of TCM, the test group and the control group were given homologue Chinese drugs preparations and model Chinese drugs. The total study period was 18 months. Using PRO scale and the world health organization AIDS determination of quality of life short scale form (WHOQOL-HIV-BREF) to investigate asymptomatic HIV infected persons, according to different times, we calculated the total score and each domain score of quality of life of the treatment group and control group, we did statistical analysis.</p><p><b>RESULT</b>Form the PRO scale,we can see that the treatment group showed a trend of stability, compared with the control group with significant statistical difference (P < 0.05) after 6 months; from the WHOQOL-HIV scale analysis, we can see that compared with before treatment, the quality of life of the treatment group was increased, the difference was significant (P < 0.05), but the quality of life of the control quality of life was decreased, the differences was significant (P < 0.05).</p><p><b>CONCLUSION</b>Dialectical therapy of Chinese medicine can significantly improve the patient's quality of life, which can provide the basis for the prevention and control policy formulation and implementation with asymptomatic HIV infected persons.</p>

Effect and mechanism of shenshuai mixture (SM) in promoting repair of kidney in acute renal failure rats / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To dynamically observe the effect of Shenshuai Mixture (SM) on repair of kidney in acute renal failure (ARF) rats.</p><p><b>METHODS</b>Male SD rats were divided into 4 groups randomly, the normal group, the SM group, the verapamil group and the model control group. Except those in the normal group were treated with normal saline without modeling, all remaining rats, after being made into ARF model by intra-muscular injection of glycerin, were treated with SM, verapamil and normal saline respectively via gastrogavage. Renal function, renal pathology, mRNA expression of epidermal growth factor (EGF) and protein expression of proliferating cell nuclear antigen (PCNA) were detected once every day from the 1st day to the 5th day. Results (1) BUN and Scr levels increased markedly 24 hrs after modeling, but the Scr level in the two treated groups was significantly lower than that in the model group (P < 0.05). Compared with that in the model group and the verapamil group, renal function was better in the SM group on the 3rd day (P < 0.01), and approach to normal level on the 5th day. (2) Renal pathological changes alleviated in every phase of ARF in the SM group than that in the model group, especially part of tubule regeneration could be seen on the 3rd day (metaphase), and renal structure was rehabilitated on the 5th day (convalescence), prior to those in the model group. (3) At the 3rd day expression of EGF mRNA and PCNA in tubule epithelial cell (TEC) increased remarkably in the SM group, higher than those in the model and verapamil group (P < 0.05).</p><p><b>CONCLUSION</b>SM could promote renal tissue regeneration and rehabilitation, and shorten the course of ARF through up-regulating mRNA expression of EGF in TEC.</p>

Experimental study on effects of Shenshuai compound medicine on acute renal failure rats and secretion cell factors / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the effect of the experiential compound prescription Shenshuai compound medicine (SSCM) on acute renal failure (ARF) rats, and expose its mechanism.</p><p><b>METHOD</b>Male SD rats were allocated into four groups at random. Except normal group, the others were injected glycerin into the musculi to induce a model of ARF. At the same time, rats in normal and model groups were given a dose (10 mL x kg(-1)) of normal saline; rats in the other two groups were given verapamil (Vp) 40 mg x kg(-1) x d(-1) and SSCM 22.5 mg x kg(-1) x d(-1) respectively by gastric gavages. In this way they were killed at 24 h after injecting glycerin.</p><p><b>RESULT</b>In contrast with model group, SSCM and Vp could ameliorate the renal function of acute tubular necrosis (ATN) rats markedly, in a way protect the renal inherent cell ultrastructure such as tubular epithelial cell etc at ATN early-stage; especially SSCM could enhance NO contents in serum, and was reduce ET levels inplasma, evidently cut down TNF-alpha contents in serum, and was partly superior to Vp.</p><p><b>CONCLUSION</b>It is indicated that SSCM can adjust thebalance of contract and stretch blood vessal active substance and clear away initiate inflammatory medium, consequently alleviate renal pathological changes, prevent and treat ARF.</p>

Effects of serum containing Xinlikang on angiotensin ii induced hypertrophy in cultured neonatal rat cardiomyocytes / 中国结合医学杂志

<p><b>OBJECTIVE</b>To evaluate the effects of Xinlikang (XLK) on angiotensin II (Ang II) induced hypertrophic cultured neonatal rat's cardiomyocyte (CMC).</p><p><b>METHODS</b>Primary cultured neonatal rat's CMCs with the purity certified by immunohistochemical technique, were divided into three groups. Rats in the normal control group were untreated; those in the model group were established into hypertrophic models but underwent no treatment; and those in the XLK group were established to hypertrophic models and treated with XLK containing serum obtained from rats with aorta coarctation after 8 days of feeding with XLK. MTT and phase-contrast microscope were used to evaluate the effect of XLK on cell activity, pulsating rhythm and surface area; Atrial natriuretic peptide (ANP) expression was determined by radioimmunoassay; Protein content was determined by Bradford method; and DNA synthesis was detected by flow cytometric assay.</p><p><b>RESULTS</b>Immunohistochemistry results showed that more than 90% of the cells were alpha-sarcometin actin stained positive cells. No significant effect of XLK on normal CMC was found. Ang II could significantly induce hypertrophy in CMCs, and XLK could significantly decrease the increased surface area and the accelerated pulsating rate in them. ANP expression was 780 +/- 38 microg/L in the model group, and 430 +/- 23 microg/L in the control group, and the elevated expression of ANP in model rats was significantly decreased in the XLK group; The DNA content in the G0/G1 and G2/M phases was significantly enhanced and at the same time it was accompanied with increase of total protein content in the model rats after being stimulated by Ang II for 24 h, showing that serum-containing XLK could also significantly suppress total protein synthesis (P < 0.05).</p><p><b>CONCLUSION</b>XLK could improve Ang II mediated pathological growth of CMCs without influencing the growth of normal CMCs, suggesting that XLK is probably an effective drug for treatment of myocardial hypertrophy and heart failure.</p>
