Objective:To study the effectiveness of Loop electrosurgical excision procedure (LEEP) in the diagnosis and management of cervical intraepithelial neoplasia(CIN). Methods: 155 patients with CIN were diagnosed by cervical biopsy under colposcopy. All cases were treated with LEEP and the operative time, bleeding volume, cervical biopsy results before and after LEEP were evaluated, and the effects and cervical regeneration were followed up. Results: The mean operative time of LEEP was 6. 8 minutes. The mean bleeding volume was 9.6m1. Pathological diagnosis of CINI CIN Ⅱ CIN Ⅲ after LEEP were positively correlated to directed biopsy by colposcopy. The correlation coefficient was 0.785 ( P < 0.01). The cure rate of LEEP was 98.6%. Among the 151 cases, 134 (88. 7%) were satisfactory cervical regeneration. Conclusions: LEEP is one of the effective and safe methods for the diagnosis and treatment of CIN.

Objective To investigate the effects of 4-aminosalicylic acid (4-ASA) on rats with 2,4,6-trinitrobenzenesulfonic acid-induced colitis in order to understand its mechanisms in treatment of inflammatory bowel disease (IBD). Methods Thirty SD rats were given 2,4,6-trinitrobenzenesulfonic acid to induce colitis and were divided into model group, 5-ASA (200 mg/kg) treated group and 4-ASA (200 mg/kg) treated group with 10 each. Another 10 rats were severed as normal control. Seven days later,all animals were sacraficed for estimation of colonic tissues. The iNOS and serum level of interleukin (IL)-8 were detected by immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) ,respectively. And the apoptosis of polymorphonuclear neutrophil (PMN) was examined by flow cytometry. Results In comparison with model group, the body weight was increased in rats treated with 4-ASA (t= 14.09,P<0.01), whereas the macroscopic and histological scores and MPO activity were decreased (t=7.87,18.37,6.66 and 19.60,respectively, all P values <0.01), which were similar to 5-ASA treated group (all P values > 0. 05). The expression of tissue iNOS was 73.55%±5.15% in model group, which was higher than that in control group [(5.95±1.45)% ,t=39.93,P<0.01)],but was lower than that in 5-ASA treated group [(37.80±3.82)%,t = 17.62,P<0.01] and 4-ASA treated group [(42.27±3.52) %, t= 15.76 ,P<0.01]. The serum level of IL-8 in model group was significantly higher than that in 5-ASA treated group and 4-ASA treated group (P<0. 01). The apoptosis of PMN in model group was lower than that in control group (t= 11.48,P<0.01), but higher than that in 5-ASA treated group (t= 7.51, P<0.01) and 4-ASA treated group (t= 10.47,P<0.01). Conclusions The efficacy of 4-ASA in treatment of IBD may be related to the mechanisms of reducing the migration and the activities of PMN, up-regulating PMN apoptosis and scavenging reactive oxygen radicals produced by PMN.

Objective To investigate the effects of Gefarnate on expression of myeloperoxidase (MPO),cyelooxygenase-1 (COX-1) and COX-2 in trinitrobenzene sulphonic acid (TNBS) induced experimental colitis in rats and its therapeutic effects on ulcerative colitis. Methods Forty female Sprague-Dawley (SD) rats were randomly divided into 4 groups with 10 each. The rats in group A, B and C were infused with TNBS/alcohol by enema. After the production of colitis, the rats in group A or B were treated daily with 1 ml of normal saline or with 1 ml of 5-ASA (100 mg/kg) by enema,and those in group C were treated daily with 1 ml of Gefarnate by gavage. Group D was served as normal control. After the production of colitis,animals were sacrificed at day 7 and 14 with 5 in each group. The macroscopic changes of the colon were evaluated according to disease activity index (DAD scoring and histological change was assessed by HE staining. MPO activity of the mucosa was detected by biochemical methods. Expressions of COX-1 and COX-2 in tissues were detected by immunohistochemistry. Results Compared with group A, macroscopic and histological scores and MPO activity were significantly decreased in group B and C (P<0.05). The expressions of COX-1 at day 7 and 14 were 1.86±0.51 and 1.96±0.41 in group B, 1.73±0.68 and 1.79±0.6 in group C, 1.91±0.34 and 1.99±0.45 in group D, respectively, which were significantly higher than those in group A (0.87±0.18 and 0.93±0.15, P<0.05). Whereas the expressions of COX-2 at day 7 and 14 were 1.53±0.19 and 0.73±0.15 in group B, 1.73±0.94 and 0.86±0.29 in group C, 0.24±0.18 and 0.18±0. 16 in group D, respectivley, which were significantly lower that those in group A (3.50±0.2;3 and 3.06±0.27). There was a significant difference between group D and group B or C (P<0.05). Conclusions Gefarnate provides a therapeutic effect during TNBS-induced colitis in rats, which is similar to that of 5-ASA. The mechanisms are involved in decreasing the concentration of colonic MPO and regulating the expression of COX-1/COX-2.

This study is to investigate the effects of paeoniflorin on cerebral blood flow and the balance of PGI2/TXA2 of rats with focal cerebral ischemia-reperfusion injury. A total of 72 SD rats (3) were randomly divided into 6 groups: sham operation group, cerebral ischemia-reperfusion model group (I/R gourp), low (10 mg.kg-1), middle (20 mg.kg-1) and high (40 mg.kg-1) doses of paeoniflorin groups and nimrnodipine group. Focal cerebral ischemia in rats was made by inserting a monofilament suture into internal carotid artery for 90 min and then reperfused for 24 h. The effects of paeoniflorin on neurological deficit scores and the infarction volume of brain were detected. Relative regional cerebral blood flow (rCBF) was continuously monitored over ischemic hemispheres by laser-Doppler flowmetry (LDF). The expression of COX-2 in hippocampal CAl region was estimated by immunohistochemistry and the contents of prostacyclin I2 (PGI2), thromboxane A2 (TXA2), and ratio of PGIJ2/TXA2 in serum were measured by ELISA kits. Paeoniflorin significantly ameliorated neurological scores, reduced the infarction volume, and increased regional cerebral blood flow relative to the I/R group. In addition, paeoniflorin could inhibit COX-2 expression and the release of TXA2 and prevent the downregulation of PGI2 induced by I/R injury. The neuroprotective effects of paeoniflorin against focal cerebral ischemia-reperfusion rats might be attributed to improve the supply of injured hemisphere blood flow and adjust the balance between PGI2/TXA2.

Aim Toinvestigatetheeffectofhigh,me-dium and low doses of Mahuang decoction on the re-lease amount of rat hippocampal neural transmitter (Glu,Gly,Asp,GABA),then compare Mahuang de-contion with ephedra alkaloids and ephedra.Methods Ratswererandomlydividedinto6groupsandgiven orally with Mahuang decoction of high dose (calculated by ephedra 4 g·kg-1 ),medium dose (calculated by ephedra 2 g·kg-1 ),low dose (calculated by ephedra 1 g · kg-1 ),ephedra (calculated by ephedra 2 g · kg-1 ),ephedra alkaloids (ephedrine 7 mg · kg-1 , pseudoephedrine 2. 4 mg · kg-1 , methylephedrine 1. 12 mg · kg-1 )and blank control group.Samples were obtained from the hippocampus of conscious rat by microdialysis sampling technique.The content of ami-no acid neurotransmitters in dialysates was detected u-sing the established HPLC-ECD with OPA pre-column derivationmethod.Results Fouraminoacidneuro-transmitters could be well separated in 28 min.High, medium and low doses of Mahuang decoction,ephedra and ephedra alkaloids significantly increased the con-tent of these four amino acid neurotransmitters,com-pared with blank control group (P<0. 05 ).Ephedra alkaloids significantly reduced the levels of inhibitoryamino acid neurotransmitters GABA and Gly in 90 min,compared with the medium dose of Mahuang de-coction.Excitatory neurotransmitters of ASP and Glu in hippocampus showed the trend of increase first and then decrease after oral administration of Mahuang de-coction and ephedra. The levels of Glu and Asp reached peaks from 90 min to 120 min after treatment with Mahuang decoction,and also increased along with dose increase of Mahuang decoction.In comparison with the medium dose of Mahuang decoction group,the level of Glu reached peak at 90 min and 150 min in ephedra alkaloids group and ephedra group respective-ly,and the content of Glu significantly increased at peaktime.Conclusions Increasedcontentofexcita-tory amino acid neurotransmitters (Asp and Glu ) shows positive correlation with the dose of Mahuang de-coction.Other components in Mahuang decoction in-hibits the up-regulation effect of ephedra and ephedra alkaloids on Glu,and promotes the up-regulation effect of ephedra alkaloids on GABA and Gly.

Objective To clinically observe and verificate the advantages of treating infantile anorexia of spleen-dysfunction in transportation with infantile massage and Chinese medicine based on the thought of “invigo-rating spleen and nourishing qi”. Methods Multi-central large-sample randomized controlled trial was carried out in Guangzhou, Shenzhen, and Foshan. Five hundreds cases of infantile anorexia of spleen-dysfunction in transportation were randomized into infantile massage group, Chinese medicine group, infantile massage combined with Chinese medicine group and Western medicine group and two sessions of treatment were required in each group. Separately, during the enrollment, after 2 sessions of treatment, infantile anorexia signs and symptoms scale , the related therapeutic effect criterion from clinical guideline of new drugs for traditional Chinese medicine, the expression level of hemoglobin and blood zinc were adopted for efficacy assessment. Results A mong 4 groups , the recovery rate and the total effective rate of infantile massage combined with Chinese medicine group were better than those of other groups (P < 0.05). The expression level of hemoglobin and blood zinc of 4 groups both increased obviously (all P < 0.01), but more improvement was found in infantile massage combined with Chinese medicine group (both P < 0.05). Conclusion The treatment of infantile anorexia with infantile massage and Chinese medicine based on the thought of invigorating spleen and nourishing qi has a significant effect.

ObjectiveTo evaluate the effect of auscultation, partial pressure of carbon dioxide in end-expiration (PETCO2), transillumination technique to judge whether the endotracheal tube is misplaced into the esophagus. Methods A blinded randomized controlled trial was conducted. Sixty patients with American Society of Anesthesiology (ASA) gradeⅠ-Ⅱundergoing endotracheal intubation in Fengxian Central Hospital admitted from September 2014 to February 2015 were enrolled. Two endotracheal tubes with the same size were respectively inserted into the trachea and esophagus for the same depth after general anesthesia by the same person. Two blinded anesthetists with different experience checked the tube position using three methods including auscultation, PETCO2, and transillumination technique, respectively. The order of the tubes tested (trachea or esophagus) and the method used were randomized according to randomise numbers table. The experienced anesthetists conducted the test first, followed by an inexperienced anesthetist conducting the same methods. The numbers of right and wrong determinations with different methods by different anesthetists were recorded.Results Sixty patients underwent the procedures for 180 times, with intratracheal intubation for 90 times, and esophageal intubation for 90 times. It was shown that the results were not different in two groups [96.7% (174/180) vs. 92.2% (166/180),χ2 = 3.500,P = 0.057]. By using auscultation, the correct rate of experienced anesthetist was higher than that of inexperienced (95.0% vs. 78.3%,χ2 = 5.786,P = 0.013). Using PETCO2, both anesthetists were correct in all cases, and the accuracy was 100%. Using transillumination, the experienced anesthetist was mistaken in 3 cases (accuracy was 95.0%), while the inexperienced mistook in 1 case (accuracy was 98.3%), and no significant difference was found between two groups (χ2 = 0.500,P = 0.250). The correct rate of using transilluminaion was significantly higher than that of using auscultation (χ2 = 7.563,P = 0.004). The sensitivity and specificity of the auscultation was 70.0% and 80.0%, that of transillumination technique was 96.7% and 93.3%,and PETCO2 was 100%, respectively, for two groups.ConclusionsPETCO2 is the most reliable method for determining tube position, and it is superior to auscultation and transilluminaion. Transillumintaion technique is superior to auscultation, irrespective of anesthetists' experience, while the accuracy of auscultation showed an obvious relationship with the anesthetists' experience.
