Journal of Chongqing Medical University 2007;0(07):-
Objective:To investigate the current status of periodontal diseases in the population at the age of 12,35~44 and 65~74 years in Chongqing,to provide information for the establishment of oral health care policies in Chongqing. Methods:A stratified equal-sized randomly sampling design was applied to obtain 751 objects aged at 12 years old,723 objects aged at 35~44 years old and 722 objects aged at 65~74 years old of three cities and three rural areas in Chongqing. The status of gingival bleeding,dental calculus,periodontal pocket and loss of attachment were assessed according to "The Guidline for the Third National Oral Health Survey" by using a CPI prode.The detection rates were calculated and were compared in aspect of area and gender. Results:In the group aged 12,the detection rates of gingival bleeding and dental calculus were 79.49% and 86.68% respectively and the detection rates of dental calculus in rural areas were higher than that of urban residents(P

5.Comparison of the analgesic efficacy between the epidural and intravenous analgesia after spinal fusion:a Meta-analysis
Chinese Journal of Spine and Spinal Cord 2014;(5):433-439
Objectives: To compare the efficacy of patient-controlled epidural analgesia and patient-controlled intravenous analgesia in postoperative analgesia after spinal fusion. Methods: The CNKI, Wanfang, CBM, Pubmed, Embase, Ovid, Cochrane library databases were searched by computer. The randomized controlled trails with patient-controlled epidural analgesia or patient-controlled intravenous analgesia after spinal fusion published from May 1985 to July 2013 were selected. All of them were assessed by the standard of Cochrane systematic review. Data of postoperative VAS and the rate of side effects after using the analgesic drugs were extracted into an electrical sheet, which was synthesized by a Meta-analysis with RevMan 5.2 software. Re-sult: Eight randomized controlled trails involving 482 patients met the inclusion criteria. And the quality grade of 3 literatures was A, 5 literatures was B. The result of meta-analysis showed that: ①Visual analogue score(VAS). The postoperative first day′s VAS[WMD=-0.47, 95%CI(-0.74, -0.20)], second day′s VAS[WMD=-0.66, 95%CI(-1.14, -0.19)] showed that the patient-controlled epidural analgesia had a good analgesic effect compared with the patient-controlled intravenous analgesia, and both had statistic differences(P<0.05). No dif-ference in the postoperative third day′s VAS[WMD=-0.58, 95%CI(-1.38, 0.21)] was observed between the two methods, and no statistic difference(P>0.05); ②The side effects. The patient-controlled epidural analgesia had a higher incidence of skin itch[RR=1.53, 95%CI(1.08, 2.16)], paresthesia[RR=3.34, 95%CI(1.12, 9.98)] after surgery than the patient-controlled intravenous analgesia, and both had statistic differences(P<0.05). While two groups had no a significant deviation about nausea [RR=1.05, 95%CI (0.79, 1.40)], vomiting [RR=0.80, 95%CI (0.48, 1.31)], and no statistic difference(P>0.05). Conclusions: The patient-controlled epidural analgesia has better analgesic effects on the postoperative first and second day after spinal fusion, but obviously has a high-er incidence of skin itch and paresthesia than the patient-controlled intravenous analgesia.
6.Conservative Therapy Compared with Operations in Early Severe Acute Pancreatitis
Journal of Chinese Physician 2001;0(03):-
Objective To explore indications of the conservative therapy an early operative treatment for severe acute pancreatitis and researching comprehensive therapeutic rule.Methods Retrospective analyze the clinical feature and the result as making a diagnosis and giving treatment of 82 cases of SAP admitted from Aug.1986 to dec.2000.Results Among them,28 cases underwent conservative treatment,with the cure rate of 85.7%,54 cases underwent conservative treatment,with the cure rate of 81.5%,the total cure rate was 82.9%.Conclusions The conservative therapy or early operation of SAP is determined by the patients' clinica feature,while the supportive conservative therapy being on,we should carefully observe the changes of the patient's condition and the response to therapy,when once surgical indication being discovered,early operation should be performed ,the emergency surgery should be performed as soon as possible for the biliary obstruction of SAP.
7.STUDY ON THE REACTION OF CHITOSAN WITH CARRAGEENAN IN SOLUTION AND THE CHARACTERISTCS OF THE COMPLEX
Chinese Journal of Marine Drugs 1994;0(01):-
Solutions of chitosan and carrageenan were co-reacted under various experimental conditions to form water-insoluble precipitates. DR. spectroscopic studies and the counter -ions analyses revealed that the combination of the polyions proceeded through the electrostatic interaction between the - NH+3 of chitosan and the - SO3 of carrageenan, and the mole retios of N/S in the poly-electrolyte complexes (PEC) thus prepared have large scope depending on pH, the degree of deacetyla-tion (DD) of chitosan as well as the mixin ratio of the complexing components. The observation of the PEC by scanning electron microscopy showed that there exist fibrous structures in some PEC depending on such reactive conditions as pH, DD of chitosan related with the charge densities of chitosan chains. The solubility of PEC, which is greatly affected by the DD of chitosans, and the blood compatibility have also been studied.

Academic Journal of Second Military Medical University 2000;0(08):-
Objective:To evaluate the long-term effectiveness of free transfer of Abductor hallucis muscle plus anastomosis of blood vessels and nerves for dynamic reanimation of the established facial paralysis.Methods: Twenty-eight patients who received the above-mentioned treatment during March 1999 to November 2006 were followed up.The follow-up period was 1 to 16 years,with a median period of 4 years.The facial pictures of frontal view were analyzed before and after operation.T-FGS and facial nerve function index(FNFI) were used to evaluate the facial nerve function before and after operation.Meanwhile,the survival of the graft,the width of the face,the scar,and the function of the foot were analyzed and compared.Results: All patients obtained satisfactory symmetric faces in static state and voluntary contraction of the transferred muscles.Twenty-two patients obtained ideal smiling faces.The T-FGS score increased by(27?7.2) points and the score of FNFI increased by(57?10.7)% after transplantation(P
9.Downregulation of actin related protein 2/3 complex subunit 5 inhibits proliferation, migration and invasion of lung squamous carcinoma cell line SK-MES-1
China Oncology 2014;(7):529-534
Background and purpose:Actin related protein 2/3 complex subunit 5 (ARPC5) is involved in the packaging of actin, and then affects the mobility of cells. It plays an important role in the formation of invadopodia of cancer cells. This study aimed to investigate the effect of ARPC5 gene-silence on cell proliferation, migration and invasion of lung squamous carcinoma cell line SK-MES-1. Methods:Under the induction of LipofectamineTM RNAiMAX, the recombinant of si-ARPC5 was transfected into SK-MES-1. The experiment set up 3 groups:blank (mock) group, negative control (NC) group and si-ARPC5 transfected group. Cell proliferation, migration and invasion assays were investigated by cell counting kit(CCK-8) method, scratch assay and Transwell Chambers respectively. Results:The result of qRT-PCR and Western blot displayed downregulation of ARPC5 in mRNA and protein level of SK-MES-1 cell. Proliferation rate of SK-MES-1 cells in 72 h after si-ARPC5 transfection was lower than those in mock and NC groups (t=7.993, t=8.681, P<0.05). Compared to the mock and NC groups, the scratch repairing rate of the si-ARPC5 group was lower [(43.32±0.23)%vs (73.11±0.43)%and (76.58±0.88)%] (t=7.348, t=10.614, P<0.05);And the number of penetrating the membrane was signiifcantly reduced [(27±6) vs (101±11) and (92±9)] (t=10.229, t=8.391,P<0.05). Conclusion:Downregulation of ARPC5 gene can inhibit the proliferation, migration, and invasion of SK-MES-1 cell.
