OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.
METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).
RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.
CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Objective: To explore the clinical characteristics of ST elevation and non-ST elevation acute myocardial infarction (AMI) related with left circumflex artery (LCX) occlusion. Methods: Clinical data of 86 consecutively enrolled patients with LCX occlusion -related AMI undergoing percutaneous coronary intervention (PCI) were retrospectively analyzed. According to manifestations of electrocardiography, the patients were divided into ST elevation myocardial infarction (STEMI) group (n=32) and non STEMI (NSTEMI) group (n=54). Clinical features and prognosis were compared between two groups. Results: Compared with NSTEMI group, there were significant increase in serum level of creatinine [(80±23) μmmol/L vs. (100±30) μmmol/L], in rates of intra-aortic balloon counterpulsation (IABP)support (3.7% vs. 18.8%), usage of invasive respiratory machine (1.9% vs. 15.6%), ischemic mitral reflux (13.0% vs. 40.6%), complete atrioventricular block (0 vs. 9.4%), proportion of left coronary artery dominant type (7.4% vs. 28.1%) and left ventricular end-diastolic diameter [LVEDd,(46±4)mm vs.(48±5)mm?]; And significant decrease in percentage of triple-vessel coronary disease (72.2% vs. 46.9%) in STEMI group, P<0.05 or <0.01. There was no significant difference in mortality rate during admission (3.1% vs. 0, P>0.05) between STEMI group and NSTEMI group. Conclusions: Compared with patients with NSTEMI, patients with STEMI have poorer heart function in patients with left circumflex artery occlusion, which may be related to more left coronary dominance.

Syndrome and formulae (or prescription) are two key issues in traditional Chinese medicine (TCM) and the premise research for material basis of TCM. However, vagueness of syndromes and complexity of formulae greatly limited the evaluation to syndromes and effective substance basis of prescription. Therefore, how to solve the evaluation of syndromes, confirming the efficacy material basis in prescription are the current hot issues of international concern. To solve these problems, establishing chinmedomics by integrated serum pharmacochemistry of TCM with metabolomics technology, that is a unique method of TCM research, made outstanding contributions in solving international concerns such as the effectiveness and security aspects of TCM. On the basis of the biological characterization of syndrome, the metabolic profiling of animal models of TCM syndrome, and related metabolic fingerprints as well as metabolic biomarkers were established to evaluate the overall effects of TCM formulae and corresponding relationship of syndrome-formulae. The active constituents were screened using the plotting of correlation between (endogenous) marker metabolites and (exogenous) serum constituents (PCMS), and is ongoing verification by further biological experiments. Correlation analysis between the ingredients in the body after oral formulae and endogenous markers in vivo can be used to clarify the active ingredients and synergistic properties. This method was successfully applied for rapid discovery of potentially bioactive components and metabolites from TCM, and through a series of studies on the chinmedomics, it proved that the established method could help to explore the effective substance for further research of TCM. As a new research approach, Chinmedomics is the best method to fit the holistic concept of TCM, and it can not only interpret the essence of syndrome but also elucidate the scientific connotation of Chinese medical formulae.

OBJECTIVETo study possible mechanisms of Shangjuxu (ST37) and the large intestine.
METHODSTotally 40 SD rats were selected. The distension of end colon was used as injured afferent stimulus. Activities of locus coeruleus (LC) neurons were recorded by extracellular microelectrode technique. Shangjuxu (ST37) and Hegu (L14) were needled to observe general features of discharge reactions, distention of colon induced discharge reactions of LC, and its effects on distention of colon induced discharge reactions of LC.
RESULTSDistention of colon could induce incrased discharge of LC neurons by 127.33% ± 45.48%. But needling at Shangjuxu (ST37) and Hegu (L14) could inhibit this injured response by 38.24% ± 7.69% and 21.29% ± 13.16% respectively (all P < 0.01).
CONCLUSIONSNeedling at Shangjuxu (ST37) and afferent signals of colon distension converged and interacted with each other. Needling at Shangjuxu (ST37) could significantly inhibit colon distension induced discharge of LC neurons, which might be one of mechanisms for Shangjuxu (ST37) and the large intestine relationship.

OBJECTIVETo study the relationship between serum load level of HBV-DNA and therapeutic effect of oxymatrine in patients with chronic hepatitis B.
METHODSForty-four patients of chronic hepatitis B were divided into two groups, the treated group was treated with oxymatrine 0.4 g/d by intramuscular injection for 3 months, the control group was treated with some liver protecting agents to estimate the therapeutic effect. The serum level of HBV-DNA was determined by quantitative polymerase chain reaction (PCR) before and after treatment.
RESULTSThe seroconversion rate of HBV-DNA and HBeAg in the treated group was 43.47% and 43.47% respectively, which was obviously better than those in the control group respectively (P < 0.05), the quantity of HBV-DNA decreased after treatment from 10(6.83 +/- 1.27) copy/ml to 10(3.35 +/- 3.08) copy/ml. Among them, in patient with HBeAg negative conversion, the pretreatment quantity of HBV-DNA was 10(6.30 +/- 1.42) copy/ml, while in those with no HBeAg negative conversion, it was 10(7.23 +/- 1.23) copy/ml, the difference was significant.
CONCLUSIONOxymatrine is effective in treating chronic hepatitis B. The therapeutic effect is better for patients with lower quantity of serum HBV-DNA.

Objective To investigate the clinical and electroencephalogram (EEG) characteristics of children with electrical status cpilepticus during sleep (ESES), and the response to medication therapy. Methods AEEG and VEEG including an entire sleeping c-ycle were performed on 26 patients with ESES. The clinical and EEG changes, neuropsychological impairment and the response to medication therapy were followed up. Results Twenty five patients had seizures,21 cases had normal psychomotor development before ESES. After the onset of the disease,Fifteen cases developed language disorder, 16 cases developed psychological and behavior abnormalities, 13 cases had both of the problems Seventeen patients belonged to epileptic syndrome. Patients in this cohort had good response to clonazepam and valproate treatment. Cortical steroid could dispel the electrical discharge. Eighteen patients had been followed up. Seizures stopped in 15 cases after treatment ESES disappeared in 16 cases, 4 of them still had neuropsychological impairment ESES sustained in 2 cases Conclusions ESES is a specific EEG phenomenon. Continue epileptic form discharge during non - rapid cye movement sleep is the major cause of neuropsychological impairment in patients with ESES. To control the seizures and electrical state are very important for the prevention and treatment of neuropsychological impairment.
