Objective: To observe the efficacy of needling the Xi-Cleft points of yang meridians plus topical surrounding needling and pregabalin in treating postherpetic neuralgia (PHN) affecting the head and face and its influence on quality of life (QOL). Methods: Eighty patients with PHN affecting the head and face were randomized into an acupuncture-medication group and a Western medication group by their visiting sequence, with 40 cases in each group. The Western medication group took pregabalin capsules orally, 75 mg each time, twice a day. The dosage could increase to 150 mg each time and twice a day within 1 week based on the efficacy and tolerance. The treatment lasted for 5 weeks. The acupuncture-medication group was given additional surrounding needling at the herpes zoster on the head and face, and Xi-Cleft points of yang meridians were chosen according to the affected area for acupuncture, once every other day, for 5 weeks in total. Results: Prior to treatment, there were no significant differences in the visual analog scale (VAS) and QOL scores between the two groups (both P>0.05). After treatment, VAS and QOL scores dropped significantly in both groups (all P<0.01), and were significantly lower in the acupuncture-medication group than in the Western medication group (both P<0.01). The total effective rate was 67.5％ in the Western medication group, versus 92.5％ in the acupuncture-medication group, and the between-group difference was statistically significant (P<0.05). Conclusion: Based on oral administration of pregabalin, needling the Xi-Cleft points of yang meridians and topical surrounding needling can reduce PHN, notably improve patients' QOL, and produce more significant efficacy than oral administration of pregabalin alone.

OBJECTIVETo evaluate the efficacy and safety of wuling Capsule combined with Pinaverium Bromide in treatment of irritable bowel syndrome (IBS).

METHODSSixty-four IBS patients were randomized into two groups, the treatment group and the control group, 32 in each group. Patients in the treatment group took wuling Capsule (0. 33 g/capsule, 3 times per day) and Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day) , while those in the control group only took Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day). The therapeutic course for all was 6 weeks. IBS symptom score questionnaire, IBS-Quality of Life (IBS-QOL) , Self-Rating Depression Scale (SDS) , and Self-Rating Anxiety Scale (SAS) were assessed before and after treatment. Adverse reactions were also observed.

RESULTSThe improvement of abdominal pain, stool frequency, and stool properties, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of dysphoria, body image, concerns for health, and dietary restriction of IBS-QOL, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of SDS and SAS, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). No severe adverse reaction occurred in either group.

CONCLUSIONCombination therapy of wuling Capsule and Pinaverium Bromide could improve abdominal pain and defecation, attenuate depression and anxiety of IBS patients with higher safety.

OBJECTIVETo evaluate the predictive value of serum iron level for in-hospital acute heart failure (AHF) after acute ST-elevated myocardial infarction (STEMI).

METHODSThis retrospective study involved 287 patients with STEMI stratified by quartiles of admission serum iron concentration. The incidence of AHF was assessed by serum iron quartiles. We evaluated the association of serum iron levels with B-type natriuretic peptide (BNP), cardiac troponin I (cTnI), and high-sensitivity C-reactive protein (hs-CRP) levels on admission, and analyzed the correlation of serum iron levels with in-hospital AHF, death, and duration of hospital stay.

RESULTSThe average serum iron level on admission of the 287 STEMI patients was 10.20 µmol/L (6.90-14.40 µmol/L), and the quartiles (Q) of serum iron levels were ≤6.90 µmol/L (Q(1)), 6.91-10.19 µmol/L (Q(2)), 10.20-14.39 µmol/L (Q(3)), and ≥14.40 µmol/L (Q(4)). The incidences of in-hospital AHF from Q(1) to Q(4) were 79.5%, 64.3%, 50.0% and 45.9%, respectively (P<0.001). Univariate logistic regression analysis showed that low admission serum iron level (Q(1)) was an independent predictor for in-hospital AHF (OR=3.358, 95%CI 1.791- 6.294, P<0.001), and multivariate logistic regression analysis showed a similar result (OR=2.316, 95%CI 1.205-4.453, P=0.012).

CONCLUSIONSA lower admission serum iron level is an independent predictor of AHF in STEMI patients during hospitalization.

OBJECTIVETo observe the effect of Baichanting Compound (BC) on dopamine (DA) in striatum of Parkinson's disease (PD) mice, and to screen the optimal component proportion.

METHODSThe PD model was established in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced C57BL/6 mice. By using uniform design, they were intervened by three extracts of BC in different proportions [Acanthopanax senticosus extract (X1): white peony root extract (X2): Uncaria rhynchophylla extract (X3) = 30.00: 34.92: 82.50, 48.00: 19.98: 72.19, 18.00: 44.88: 61.88, 36.00: 29.94: 51.56, 54.00: 15.00: 41.25, 24.00: 39.90: 30.94, 42.00: 24.96: 20.63). Equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. The dopamine (DA) content was determined by ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS). Except 10 in the normal group, 20 PD model mice were screened and divided into the model group and the BC group (with the optimal proportion) according to random digit table. BC extract in optimal proportion was administered to mice in the BC group by gastrogavage, while equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. Praxiology was observed in each group. DA content in striatum was also detected. Results Compared with the normal group, the DA content in striatum decreased significantly in the model group (P < 0.01), suggesting a successful PD modeling. Compared with the model group, the DA content in striatum increased significantly in 1 and 2 groups (P<0.05). According to results of quadratic polynomial stepwise regression statistics, the regression equation obtained was: Y = 0.265 + 0.026 X 2 - 0.056 X 3 + 0.334 x 10(-3) x X1 x X3 + 0.691 x 10(-3) X X3(2). X3 extract was the main factor influencing the effectiveness (P < 0.01). The optimal proportion of BC was predicted by the regression equation: X1 = 54.00 mg/(kg x d), X2 = 44.88 mg/(kg x d), the X3 = 82.50 mg/(kg x d). The pole climbing time was shortened, times of autonomic activities increased, DA content was elevated, all with statistical difference in BC groups (P < 0.01, P < 0.05).

CONCLUSIONBC could increase DA content in PD model mice with the optimal proportion as 54.00: 44.88: 82.50.
