OBJECTIVETo evaluate and analyze the mechanism of Pizhen for the treatment of patients with scapular muscle fasciitis.

METHODSOne hundred and sixteen patients were divided into two groups according to random number table method, 58 cases in the treatment group and 58 cases in the control group. After treatment, 109 patients were followed up, and 7 patients lost follow-up (2 cases in the treatment group and 5 patients in the control group). In the treatment group, there were 15 males and 41 females, with a mean age of (28.02 +/- 4.85) years; the course of disease ranged from 0.25 to 3 years; and the patients were treated by Pizhen once a week,and 2 weeks were one treatment course. In the control group, there were 19 males and 34 females, with a mean age of (27.23 +/- 4.54) years old; the course of disease ranged from 0.25 to 1 year; and the patients were treated by acupuncture massage instrument, 20 minutes at a time,once a day for 2 weeks. Soft tissue displacement and banana area were tested by a soft tissue tension tester, pressure value was measured by pressure measuring instrument, and VAS was recorded by pain visual analog scale record.

RESULTSThere were significant differences in tissue displacement, banana area, pressure value and VAS between two groups before and after treatment. The tissue displacement and pressure value in the treatment group were higher than those in the control group,while banana area and VAS were lower than those in the control group. In the treatment group, 30 patients healed, 13 patients got marked improvement, 12 good and 1 poor;while 16 patients healed, 19 patients got marked improvement,11 good and 7 poor in the control group. The therapeutic effects in the treatment group was better than that in the control group.

CONCLUSIONPizhen is an effective method to treat pain in patients with scapular muscle fasciitis by relaxing tendon of soft tissue around pain point of scapular and relaxing compress and stimulation of nerves.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.

METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.

RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.

CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

OBJECTIVETo observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.

METHODSModels of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively. After 4 weeks of medication, the rats were killed for examination of semen quality and determination of the expression of the apoptosis factor FasL in the testis tissue.

RESULTSCompared with the blank controls, the model rats showed significant decreases in sperm concentration ([71.99 ± 9.72] vs [10.94 ± 3.58] x 10⁶/ml, P < 0.01), motility ([48.95 ± 4.10] vs [9.31 ± 5.79]%, P < 0.01), and viability ( [82.06 ± 6.16] vs [24.03 ± 6.93]%, P < 0.01). In comparison with the model controls, the rats in the QJT groups exhibited remarkably increased sperm concentration, motility, and viability, more significantly in the high-dose group ([59.66 ± 4.53] x 10⁶/ml, [35.45 ± 5.21] %, and [61.97 ± 9.75]%) and medium-dose group ([40.89 ± 4.90] x 10⁶/ml, [24.41 ± 4.79]%, and [60.06 ± 10.62]%) (P < 0.05 or P < 0.01). The expression of FasL was markedly reduced in the low-, medium-, and high-dose QJT groups (0.5215 ± 0.0189, 0.5371 ± 0.0364, and 0.4556 ± 0.0215) as compared with that of the model controls (0.5989 ± 0.0448 ) (P < 0.05 or P < 0.01).

CONCLUSIONBy upregulating the Fas/FasL signaling pathway, Tripterygium glycosides may induce the apoptosis of spermatogenic cells and reduce sperm concentration, motility and viability, resulting in infertility. The Chinese medicine Qiangjing Tablets can improve the reproductive function of male rats by decreasing the expression of the apoptosis factor FasL in the testis.

OBJECTIVETo investigate the effect of Longbishu Capsule (, LBS), doxazosin, and combination therapy on benign prostatic hyperplasia (BPH).

METHODSA randomized, double-blind, multi-center parallel trial was conducted involving 360 patients in hospitals in Beijing (108 cases), Heilongjiang (90 cases), Sichuan (90 cases), Shanghai (72 cases), China. They were randomly assigned with central randomization method to group A (LBS placebo plus doxazosin), group B (LBS plus doxazosin) or group C (LBS plus doxazosin placebo), 120 cases for each group. The international prostate symptom score, maximum urinary flow rate, postvoid residual urine volume and prostate volume were measured for evaluating the efficacy of the three treatments.

RESULTSAt baseline, there was no significant difference in the measured variables among the three groups. After 12-month treatment, the three groups showed significant improvements in IPSS and maximum urinary flow rate from baseline (P<0.01). Although postvoid residual urine volume was not significantly different from the baseline in group A (P>0.05), it significantly decreased in group B and C (P<0.05). The incidence of adverse events were similar among the three groups.

CONCLUSIONSThe treatment of LBS alone or LBS plus doxazosin was able to significantly improve IPSS in patients with BPH. The treatments may reduce the increase in prostate volume and postvoid residual urine volume as well.

OBJECTIVETo explore the mechanism of continuous traction in treating unstable distal radius fracture.

METHODSThirty patients with unstable distal radius fractures were treated by diaplastic external fixator including 4 males and 26 females with an average age of 61 years ranging from 18 to 85 years. According to AO classification, 12 cases were type A3, 3 were type B2, 8 were type C1, 4 were type C2, 3 were type C3. The distance of the processus radial malleolus and ulnar articularis were measured through X-ray examination.

RESULTSThirty patients were followed-up for 6 to 15 months with an average of 11.2 months. The results of distance before treatment measuring in X-ray was (0.55+/-0.22) cm, and the distance after treatment was (1.07+/-0.23) cm. The distance after treatment was higher than the distance before treatment, there were significant difference between them (P<0.01).

CONCLUSIONContinuous traction by diaplastic external fixator can explain by the theory of tendon reinforced bone and ligament restoration, or distraction osteogenesis.

OBJECTIVETo investigate the distribution of hepatitis B virus genotype in Hubei province (China) and its clinical significance.

METHODSSerum samples from 190 HBV DNA positive patients with chronic HBV infection,including 52 asymptomatic HBV carriers (ASC), 56 chronic hepatitis (CH), 32 fulminant hepatic failure (FHF), 22 liver cirrhosis (LC), and 28 hepatocellular carcinoma (HCC) patients were collected and tested for HBV genotypes by type-specific primers.

RESULTSA simple and precise genotyping system based on PCR using type-specific primers was developed for the determination of genotypes of hepatitis B virus (HBV). Of the 190 patients, 140 (73.7%) were genotype B and 42 (22.1%) were genotype C. Genotype B was more prevalent in the FHF and HCC patients than in the ASC patients; the ALT value was significantly higher in genotype B than in genotype C patients. The rate of anti-HBe was significantly higher in genotype B than in genotype C except in the patients of the ASC group.

CONCLUSIONThe system we used seems to be a useful tool for the molecular diagnosis of HBV infection and for large-scale surveys. Genotype B, genotype C and BC combination exist in Hubei province, and genotype B is the major genotype in this area especially in FHF and HCC patients.

OBJECTIVETo investigate the role of mesenchymal stem cells (BMSCs) in multiple myeloma (MM) bone marrow (BM) microenrivonment and their effect on myeloma cells survival and bortezomib induced apoptosis.

METHODSBMSCs were derived from BM of untreated myeloma patients (MM-BMSCs) and healthy donors (HD-BMSCs), respectively. The phenotype, proliferation time and cytokine secretion of MM-BMSCs were detected and compared with HD-BMSCs. Then BMSCs were co-cultured with myeloma cell line NCI-H929 and bortezomib in vitro. The NCI-H929 cells proliferation and bortezomib induced cell apoptosis were investigated.

RESULTSMM-BMSCs and HD-BMSCs were isolated successfully. The phenotype of MM-BMSCs was similar to that of HD-BMSCs. Expressions of CD73, CD105, CD44 and CD29 were positive, but those of CD31, CD34, CD45 and HLA-DR (< 1%) negative. The proliferation time of MM-BMSCs was longer than that of HD-BMSCs (82 h vs 62 h, P < 0.05). Moreover, over-expressions of IL-6 and VEGF in MM-BMSCs culture supernatant were detected as compared with that in HD-BMSCs [(188.8 ± 9.4) pg/ml vs (115.0 ± 15.1) pg/ml and (1497.2 ± 39.7) pg/ml vs (1329.0 ± 21.1) pg/ml, respectively]. MM- BMSCs supported survival of the myeloma cells NCI-H929 and protected them from bortezomib induced cell apoptosis.

CONCLUSIONSMM-BMSCs is benefit for myeloma cells proliferation and against cell apoptosis induced by bortezomib. Over-expression of IL-6 and VEGF maybe play a critical role in these effects.

OBJECTIVETo detect the effect of erigeron breviscapus on the expression of vascular endothelial growth factor (VEGF) in the periodontal tissues during orthodontic tooth movement.

METHODS45 rabbits were divided into 3 groups (groups A, B and C). Groups A and B included experimental group of 1, 3, 7 and 14 days respectively. The mandibular first molar of each experimental rabbit was observed. The rabbits of group A and group B received iontophoresis with erigeron breviscapus into the right (group A-R and group B-R) and with normal sodium into the left as the control (group A-L and group B-L). Additionally, the rabbits of group B were designed orthodontic appliance, by which 0.78 N mesial force was applied to pull the mandibular first molars. Group C, group of 0 day, was no iontophoresis and orthodontic appliance as the control. After killed on schedule, the amount of experimental tooth movement was measured and the expression of VEGF was examined by immunohistochemical method.

RESULTSThe amount of experimental tooth movement increased successively from 1 to 14 days. The differences among days 3, 7 and 14 were significant in the comparison between group B-R and group B -L (P < 0.01). The expression of VEGF in groups A-R and B-L enhanced apparently compared with that in groups C and A-L (P < 0.01), but that in group B-R was the most apparent (P < 0.01). The expression of VEGF reached the peak level on day 3 in groups A-R and B-R (P < 0.01), but it reached the peak level on day 7 in group B-L (P < 0.01).

CONCLUSIONErigeron breviscapus by iontophoresis can accelerate orthodontic tooth movement, and can meanwhile up-regulate the expression of VEGF in periodontium in the earlier period of orthodontic tooth movement. Thus it can be presumed that one of its mechanisms for erigeron breviscapus to accelerate orthodontic tooth movement is erigeron breviscapus effects the metabolism and differentiation of osteoblast and osteoclast through up-regulating the expression of VEGF in periodontium.

OBJECTIVETo evaluate and analyze mechanism of Pizhen for the treatment of pain in patients with knee osteoarthritis.

METHODSEighty-five patients (85 knees) were divided into two groups according to random number table method. Among 35 patients in the experimental group, 6 patients were male and 29 patients were female, 1 patient lost follow-up, the average age was (56.65 +/- 4.89) years, and the patients were treated with Pizhen. Among 50 patients in the control group,there were 6 males and 44 females, the average age was (57.54 +/- 4.91) years, and the patients were treated with intra-articular injection with sodium hyaluronate. The VAS score and the data of algometer from the most obvious tenderness around the knee were used to evaluate the clinical effects.

RESULTSThere were significant differences of scores in the experimental group before and after treatment (P<0.01). There were significant differences of scores in the control group before and after treatment (P<0.01). After treatment, there were no statistical differences of VAS score and the data of algometer between experimental and control groups ( P>0.01). There was negative correlation between VAS score and the data of algometer.

CONCLUSIONThe Pizhen is an effective method to treat pain in patients with knee osteoarthritis by relaxing tendon of soft tissue around pain point of knee joint, and relaxing compress and stimulation of nerves.
