Objective: To compare the curative efficacy and safety of electro-acupuncture on Jianyu (LI 15) with oral administration of Diclofenac Sodium Sustained-release Capsules in treating shoulder periarthritis. Method: Randomized controlled trials (RCT) were adopted in the study. The patients were randomized into two groups, 30 cases in one group.Electroacupuncture was done on Jianyu (LI 15) 20 min every time in the treatment group,while 75 mg Diclofenac Sodium Sustained-release Capsules were orally administered in the control group. For all the patients in two groups, one treatment course contains 7 days. Then the curative efficacy was evaluated by the efficacy evaluation criteria after two consecutive courses. Result: The total effective rate of treatment group and control group were 93.3% and 56.7% respectively. Conclusion: Electroacupuncture on Jianyu (LI 15) is an effective therapy for shoulder periarthritis and has more significant effect than oral Diclofenac Sodium Sustained-release Capsules.

Objective To evaluate the relationship between pathogenesis of preeclampsia (PE) and the ultrastructure change of the endoplasmic reticulum in trophocyte, mRNA and protein expression levels of endoplasmic reticulum molecular chaperone glucose-regulated protein 78 (GRP78), glucose-regulated protein 94 (GRP94), endoplasmic reticulum apoptosis factor cysteine protease protein 12 (caspase-12).Methods Sixty-five pregnant women who were hospitalized in the First Affiliated Hospital of Nanjing Medical University from July 2008 to January 2010, were selected as the subject. Thirty pregnancy women diagnosed with PE were divided into PE group and 35 normal pregnant women were used as control group.Electron Microscopy was used to measure ultrastructure change of the endoplasmic reticulum in placenta trophocyte. Reverse transcription(RT) PCR and western blot were used to investigute the expression levels of GRP78, GRP94, caspase-12 mRNA and protein in placenta. Results (1) In control group the volume of endoplasmic reticulum does not increase; no swelling and no expansion of endoplasmic reticulum was found.In PE group the edema number of endoplasmic reticulum was reduced; the volume of endoplasmic reticulum increased; expansion and vacuolation of cavity and degranulation of the endoplasmic reticulum was observed significantly. (2) The mRNA and protein expression levels of GRP78 in placenta of PE group (2.59 ± 0. 09 and 0. 81 ±0. 31) were significantly higher than those in placenta of control group (1. 16 ±0. 07 and 0. 40 ± 0. 10, P <0. 01). (3) The mRNA and protein expression levels of GRP94 in placenta of PE group (1.31 ± 0. 91 and 0. 55 ±0. 24) were significantly higher than those in placenta of control group (0. 63 ±0. 57 and 0. 22 ±0. 09, P < 0. 01). (4) The mRNA and protein expression levels of caspase-12 in placenta of PE group (4. 03 ± 0. 65 and 1.56 ± 0. 17) were significantly higher than those in placenta of control group (1.85 ± 0. 85 and 0. 91 ± 0. 69, P < 0. 01). Conclusion The obvious expansion of endoplasmic reticulum in trophocyte and the increased expression levels of GRP78, GRP94 and caspase-12 indicate that endoplasmic reticulum stress-mediated apoptosis may be involved in the pathophysiological processes of PE.

Objective To compare dexmedetomidine administered via different routes for epidural anesthesia during second cesarean section.Methods Sixty parturients who were at full term with a singleton fetus,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 22-38 yr,weighing 58-84 kg,undergoing a second caesarean section under epidural anesthesia,were divided into 3 groups (n=20 each) using a random number table:Ⅳ infusion of dexmedetomidine conbined with epidural injection of ropivacaine group (VDER group),epidural injection of a mixture of ropivacaine and dexmedetomidine group (ERD group) and epidural injection of ropivacaine group (ER group).The epidural puncture was performed at L2,3.After identification of the epidural space and a negative aspiration test for blood or cerebrospinal fluid,the mixture of 0.75％ ropivacaine 15 ml and 0.9％ normal saline 2 ml was injected epidurally,and dexmedetomidine 1 μg/kg was intravenously infused for 10 min at the same time in VDER group;the mixture of 0.75％ ropivacaine 15 ml and 1 μg/kg dexmedetomidine 2 ml was injected epidurally in ERD group;the mixture of 0.75％ ropivacaine 15 ml and 0.9％ normal saline 2 ml was injected epidurally in ER group.The onset time of epidural block,maximum level ofepidural block,time to reach the maximum epidural block and time of sensory block were recorded.Ramsay sedation scores were assessed at 30 miu after the end of epidural administration,and intraoperative traction reaction was also assessed.The development of hypotension,bradycardia,respiratory depressim and shivering was observed.The number of patients in whom remifentanil was used before delivery and Apgar scores at 1 and 5 min after birth were recorded.Results Compared with VDER group and ER group,the onset time and time to reach the maximum epidural block were significantly shortened,and the time of sensory block was prolonged in ERD group (P＜0.05).Compared with ER group,the rate of satisfactory sedation was significantly increased,the number of patients in whom remifentanil was used before delivery was decreased,the degree of intraoperative traction reaclion was mitigated,and the incidence of respiratory depression and shivering was decreased (P＜0.05),and no significant change was found in Apgar scores at 1 and 5 min after birth in VDER and ERD groups (P＞0.05).Conclusion Both Ⅳ and epidural dexmedetomidine can enhance the efficacy of epidural anesthesia during second cesarean section,producing no adverse effects on neonates;epidural injection of a mixture of ropivacaine and dexmedetomidine provides faster onset and prolonged time of sensory block,which is helpful for postoperative analgesia.

Objective To investigate the prevalence of mite sensitivity in patients with urticaria or other skin rashes, and to observe the clinical efficacy of a specific immunotherapy(SIT) by the Injectio dermatophagoidei farinae for the patients.Methods In 7-year period(1998-2005), skin prick test(SPT) with a dust mite(Df) allergen was carried out to detect the prevalence of mite sensitivity in OPD patients suffering from skin rashes.Among the patients sensitive to mite with SPT ≥++ response, 3 groups were established.In group A, routine SIT with Injectio dermatophagoidei farinae was conducted.In 9-week increasing dose phase, three stepwise increasing volumes(0.3ml, 0.6 ml and 1.0 ml) each case was injected subcutaneously with mite concentration of 1 ∶ 100 000(w/v) , 1 ∶ 10 000(w/v) or 1 ∶ 5 000(w/v) respectively once a week, followed by a maintenance dose phase for an injection with 1 ∶ 5 000(w/v) 1.0 ml/wk for 6 weeks.Group B received rush SIT with mite injections.A total of 15 injections in a course of therapy with same concentration and volume was given as those for the routine ones except shortened intervals, namely, 9 initial injections completed in 3 days by three injections of each concentration per day with two 30 min intervals, maintenancedoses were then provided in 6 days with 1 ∶ 5 000(w/v) 1.0 ml/d.Thereafter, both groups A and B were maintained for one year with a dose of 1 ∶ 5 000(w/v) 1.0 ml every 2 wk.Group C received antihistamine treatment as control, the patients received daily oral Ebastine 10 mg in the morning and Cetirizine dihydrochloride 10 mg in the evening for one week course and pro re nata later.Levels of serum tIgE and serum mite sIgE were detected by ELISA in 20 urticaria cases before and after one year mite SIT.Results Altogether, 2 685 cases with skin rashes were detected by Df allergen SPT.The prevalence of urticaria cases sensitive to mite was 70.3%(1 754/2 496), which was higher than that of eczema 63.5%(54/85) and anaphylactoid purpura 60.6%(63/104)(P

The hydrophilicity of the normal decoction pieces (NDP) of Indigo Naturalis is not good, therefore, it is not suit for decoctions. In this paper, powder modification technology is used and some NDP and alcohol are ground together in the vibromill to prepare the hydrophilic decoction pieces (HDP) of Indigo Naturalis. Initially, the properties of NDP, ultrafine decoction pieces (UDP) and HDP are compared, the hydrophilicity of UDP was promoted slightly, that of HDP is promoted dramatically. Then, three batches of Indigo Naturalis are prepared to HDP separately, but there is no obvious difference in the contact angle. Furthermore, the size distribution, surface area and micro-shape of HDP are bigger than that of UDP and smaller than NDP. The contents of indigo and indirubin in three decoction pieces are the same, as well as the species of inorganic substance, although there is a little difference in the proportion of five inorganic substances. The fact suggests the change of physical state and the qualitative and quantitative change of organism and inorganic substances are not the main factors to influence the hydrophilicity. In addition, hydroxyl, methylene and methyl can be identified at the wavenumber of 3 356 cm(-1) and 1 461 cm(-1) in infrared spectrum; the content of alcohol in HDP is 0.67% measured by gas chromatogram. The stability of HDP in the heating condition is studied, the fact suggests the hydrophilic effect of HDP at 40 degrees C is relatively stable. All above research suggests that the alcohol is the main factor to influence the hydrophilicity and maybe the intermolecular force which fixed alcohol molecule on the surface of Indigo Naturalis is the basic principle to produce the hydrophilicity.
