The Rhei Radix et Rhizoma was one of the most widely used traditional Chinese medicine for its special biological activities. The content of rhein, one of its major compounds, was an important standard for the quantity control of Rhei Radix et Rhizoma. The major method used for the detection of rhein was instrumental analysis like HPLC, but it was complex, time-consuming and cannot detect large samples at the same time. The enzyme-linked imunmosorbent assay (ELISA) was accurate, reliable, simple, low costs, and of a high-throughout. Recently, it was widely used for the determination of those small molecule compounds in some traditional Chinese medicinal plants. In this study, an artificial antigen were synthesized by the carbodiimide (CDI) method. Rhein-bovine (rhein-BSA) conju gate and rhein-ovalbumin (rhein-OVA) conjugate, were produced as the immunogen and coating antigen, respectively. The conjugate and the hapten number in the conjugate were determined by UV-Vis spectrophotometry (UV). The conjugation ratio of Rhein and BSA was about 4.0:1, rhein acid and OVA was 2.6 : 1, respectively. Rhein-BSA conjugate was used to immunize Bal b/c mice to produce antiserum. The antiserum titer of the Rhein were higher than 8000 detected by ELISA. The successfully synthesized conjugate antigen rhein-BSA implies its feasibility in the establishment of fast immunoassay for the rhein content determination.

Objective: To observe the effect of acupuncture plus thunder-fire moxibustion on the expressions of matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-β1 (TGF-β1) in cartilage of knee osteoarthritis (KOA) rats, and to explore the mechanism of acupuncture plus thunder-fire moxibustion in the treatment of KOA. Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a blank control group, a model group and an acupuncture-moxibustion group by random digits table, 10 rats in each group. Rats in the model group and the acupuncture-moxibustion group were injected with papain in the right posterior knee joint to prepare the models. The levels of MMP-3 and TIMP-1 in rat synovium of each group were measured by enzyme-linked immunosorbent assay (ELISA) after 2 weeks of treatment. The level of TGF-β1 was determined by Motic B5 Micro-camera system. Results:The levels of MMP-3 and TIMP-1 in the cartilage of the model group were significantly higher than those in the blank control group (allP<0.01); the levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were lower than those in the model group, and the between-group differences were statistically significant (all P<0.05). The levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were higher than those in the blank control group, and the differences were statistically significant (all P<0.05). The level of TGF-β1 in cartilage tissues of the model group was significantly lower than that in the blank control group (P<0.01); the level of TGF-β1 in the acupuncture-moxibustion group was higher than that in the model group (P<0.05), but it was lower than that in the blank control group, and the between-group difference was statistically significant (P<0.05). Conclusion: Acupuncture plus thunder-fire moxibustion can effectively recover the abnormal expressions of MMP-3 and TIMP-1 in KOA model rats and somewhat up-regulate TGF-β1, which may be one of its mechanisms of acupuncture plus thunder-fire for KOA.

ABSTRACT:Objective To evaluate the curative effect of tension-free vaginal tape-obturator (TVT-O)and modified TVT-O in treating female stress urinary incontinence (SUI).Methods We selected 1 1 3 female patients diagnosed with SUI from January to December 2013 in our department and divided them into standard TVT-O group (group A,5 6 cases)and modified TVT-O group (group B,5 7 cases).We evaluated prospectively the safety,short-term efficacy and complications of operation in the two groups.Results The length from bilateral obturator membrane to the puncture point in the skin was greater in group A than in group B.The average intraoperative blood loss was more in group A than in group B.The median NRS score of postoperatie thigh pain in group A was higher than in group B (P<0 .0 5 ).The two groups did not differ significantly in operation duration,postoperative catheterization,mean hospital stay duration,the length and position from bilateral obturator membrane to the puncture point,or surgical efficacy (P>0.05).Conclusion Both TVT-O and modified TVT-O techniques are effective in treating female SUI.Modified TVT-O has a short path to get through the adductor muscles and less intraoperative blood loss;therefore,it can significantly reduce the complications such as postoperative pain to enhance the quality of life after operation. 

OBJECTIVETo investigate the role and significance of P38-MAPK in the pathological process of hypoxic hypercapnia pulmonary hypertension in rats, and the protection of panax notoginoside (PNS).

METHODS(1) To set up rat pathological model of hypoxic hypercapnia pulmonary hypertension: seventy two male SD rats (200 280 g) were randomly divided into six groups (n = 12), which were normal group (N group), hypoxic hypercapnia for 3-day group (H3d), hypoxic hypercapnia for 1-week group(H1w), hypoxic hypercapnia for 2-week group (H2w), hypoxic hypercapnia for 4-week group (H4w) and PNS-injected group (Hp). The rats of PNS -injected group were injected PNS before being placed in the chamber (50 mg/(kg x d), ip), and other groups were injected normal sodium (2 ml/kg, ip). (2) The shapes of pulmonary artery were detected by HE staining. (3) Western blot was used to study the protein expression of p38-MAPK. The expression of p38-MAPK in lung tissue and pulmonary blood vessel was investigated by immunohistochemistry.

RESULTS(1) The ratio of vessel wall area/total area (WA/ TA) in H1w, H2w, H4w and Hp group was higher than that of N group (P < 0.05), but that of H3d group did not change obviously (P > 0. 05 vs N group). The ratio of WA/TA in Hp group was obviously lower than that of H4w, group (P < 0.05). (2) The levels of P-p38 protein was markedly ascended in H3d group (0.225 +/- 0.071) compared with N group (0.012 +/- 0.006), and expression of P-p38 protein was significantly positive in H1w, H2w, H4w groups. (P < 0.05). (3) As P-p38 protein in pulmonary arterial tunica intima and tunica media, sterile expression in N group (0.099 +/- 0.015) and H3d group (0.107 +/- 0.013) contrasted to H4w group (0.124 +/- 0.025, P < 0.05), then tended to rise in H2w, H4w group (P < 0.05). (4) In pulmonary tissue, the levels of P-p38 protein in PNS-injected group were lower 53.02% (P < 0.05) than those in H4w group. In pulmonary arterial tunica intima and tunica media the levels of P-p38 protein in PNS-injected group were lower 87.33% (P < 0.05) than those in H4w group.

CONCLUSIONp38-MAPK as a signal transduction may play an important role in the development of hypoxia induced pulmonary hypertension. The effect of PNS on reducing pulmonary hypertension and improving pulmonary vascular wall remodeling may be related to its inhibiting expression of p38 MAPK.

Objective To evaluated the clinical results of treatment of osteonecrosis of the femoral head(ONFH)by using bone flap pedicled with gluteal muscle branch of ascending branch of the lateral femo- ral circumflex artery and transversal branch of the lateral femoral cireumflex artery.Methods Bone flap pedicled with double blood vessels was applied in 32 hips with stageⅡandⅢONFH according to the Fieat staging system.Fifteen hips were in stageⅡand 17 were in stageⅢ.All patients were followed up for a mean of 25 months(range,15-38 months)and were assessed clinically and radiologically according to Harris sco- ring.Selective digital subtraction angiography was performed in 9 cases to confirm the blood reconstruction of femoral head.Results Two cases underwent total hip replacement postoperatively.Preoperative and postop- erative Harris score were 55 and 88.6.Clinical success rate was 90.6% and radiological success rate was 87.5%.DSA demonstrated blood supply was found reconstruction in the necrotic femoral head.Conclusion Transplantation of bone flap pedicled with gluteal muscle branch of ascending branch of the lateral femoral circumflex artery and transversal branch of the lateral femoral circumflex artery appears to be a effective treat- ment for osteonecrosis of the femoral head,blood supply of bone flap and blood reconstruction of femoral head was confirmed.Early clinical results were satisfied.

A sensitive antibody-based lateral flow dipstick was developed for ginsenoside Re (GRe) detection. The stick consisted of a sample pad, a conjugate pad, membrane and an absorbent pad. The membrane was coated with two capture reagents, GRe-BSA conjugate and goat anti-mouse antibodies, forming a test line and a control line, respectively. The conjugate pad was saturated with colloidal gold particles coated with affinity purified monoclonal anti-GRe antibody. The visual detection limit was 200 microg x L(-1) of GRe and the reaction time was 10 min. The Panax ginseng roots were identified after these samples (10 mg) were extracted with 5 mL tap water for 30 min at room temperature, and the extracts were tested by the dipsticks and ELISA kit. The true and false P. ginseng could be distinguished with dipsticks. The dipstick could be used to detect the quality of the P. ginseng samples when the extract was diluted 100-folds. The results were compared with those obtained using an indirect competitive enzyme-linked immunosorbent assay (icELISA). The dipstick assay proved to be a sensitive and rapid tool for quality control of P. ginseng.

OBJECTIVETo investigate the safety and efficiency of the disposable circumcision suture device (DCSD) in the surgical treatment of phimosis and redundant prepuce.

METHODSWe randomly assigned 249 outpatients with phimosis or redundant prepuce to be treated with DCSD (n = 129) and by conventional circumcision (CC, n = 120), respectively. Then we compared the safety and efficiency of the two strategies.

RESULTSComparisons between DCSD and CC showed that the operation time was (4.02 +/- 0.69) vs (30.8 +/- 4.05) min, blood loss was (1.07 +/- 1.29) vs (8.72 +/- 2.15) ml, intraoperative pain score was 0.81 +/- 0.81 vs 2.42 +/- 1.15, 24-hour postoperative pain score was 1.84 +/- 1.02 vs 4.99 +/- 1.36, postoperative complication rate was 13. 95% (18/129) vs 9.17% (11/120), wound healing time was (13.99 +/- 9.06) vs (17.48 +/- 3.49) d, satisfaction with the penile appearance was 98.4% (127/129) vs 95% (109/120), and treatment cost was (2215.62 +/- 17.67) vs (576.47 + 15.58) Y RMB. DCSD exhibited obvious superiority over CC for shorter operation time, less blood loss, milder intraoperative pain, sooner wound healing, and better penile appearance, but it also had a higher rate of postoperative complications (P > 0.05) and involved more treatment cost than the latter (P < 0.05).

CONCLUSIONThe disposable circumcision suture device affords ideal clinical effects and therefore deserves clinical popularization.

To explore an efficient strategy for further development of anticancer fluoroquinolone candidates derived from ciprofloxacin, a heterocyclic ring as the bioisosteric replacement of C3 carboxyl group led to a key intermediate, oxadiazole thiol (5), which was further modified to the bis-oxadiazole methylsulfides (7a-7h) and the corresponding dimethylpiperazinium iodides (8a-8h), respectively. Structures were characterized by elemental analysis and spectra data, and their anticancer activities in vitro against CHO, HL60 and L1210 cancer cells were also evaluated by MTT assay. The preliminary results show that piperazinium compounds (8) possess more potent activity than that of corresponding free bases (7).
