OBJECTIVETo compare the efficacy difference between triple acupuncture method at cervical Jiaji (EX-B 2) and conventional acupuncture for cervicogenic headache.

METHODSA total of 66 patients were randomly divided into a triple acupuncture group and a conventional acupuncture group, 33 cases in each one. The acupoints selected in the two groups were identical, including C1 to C7 of cervical Jiaji (EX-B 2) as well as Baihui (GV 20), Qiangjian (GV 18), Naokong (GB 19), Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), etc. The conven- tional acupuncture was performed at acupoints on the head in the two groups; triple acupuncture was performed at cervical Jiaji (EX-B 2) in the triple acupuncture group while perpendicular acupuncture was performed with a depth of 25 to 40 mm in the conventional acupuncture group. The treatment was given once a day. Five treatments were considered as one session and totally two sessions were required. The changes of simplified McGill scale before and after acupuncture were observed in the two groups, and the efficacy of the two groups was compared.

RESULTSAfter acupuncture, the simplified McGill scale was both reduced in the two groups (both P < 0.01), and there was no significant difference between the two groups after treatment (all P > 0.05). The cured and markedly effective rate was 75.8% (25/33) and the total effective rate was 93.9% (31/33) in the triple acupuncture group, which were superior to 57.6% (19/33, P < 0.01) and 84.8% (28/33, P < 0.05) in the conventional acupuncture group respectively.

CONCLUSIONThe efficacy of triple acupuncture method at cervical Jiaji (EX-B 2) is superior to that of conventional acupuncture for cervicogenic headache.

Objective To develop a questionnaire which measures leisure satisfaction for university students. Methods Initial items of the questionnaire were compiled according to theoretical analysis and interviews. 400 college students were recruited to respond to the items. The explorative factor analysis was used to decide the final items and dimensions. Another 350 college students were recruited to respond to the decided questionnaire and a criterion questionnaire. Results The leisure satisfaction questionnaire consisted of three dimensions : Relaxing Satisfaction (RS) , Contacting Satisfaction (CS), and Transcend Satisfaction (TS). Internal consistency (Cronbach' sα) of the three dimensions were 0.86,085 and 0. 84 and the Cuttmann Split-half Coefficient were 0.76,0.83 and 0.86. The cumulative explanation of the variance was 58.956%. A confirmative factor analysis revealed that the three-dimension model was proper(x2/df = 1. 74, NFI = 0.88, NNFI = 0.93, CFI = 0.94, GFI =0.93,AGFI=0.91,IFI=0.94,RMSEA =0.048). The leisure satisfaction Questionnaire was positively related to freedom satisfaction( r = 0.20 ～ 0. 30, P < 0.01). Conclusion The leisure satisfaction questionnaire for university students has satisfactory psychometric characteristics.

Objective:To establish a volt-ampere polarography method for the determination of thimerosal in chondroitin sulfate eye drops, and study the adsorption of thimerosal in different packing materials. Methods:The hanging mercury drop electrode ( HM-DE) in multi-functional electrode was used and the sample solution was added to potassium chloride-hydrochloric acid buffer solution. Nitrogen deoxygenation time was 200 s, the enrichment time was 60 s, and the equilibrium time was 5 s. The potentiometric scan was performed using a two standard addition method. Results:Thimerosal had a good linear relationship within the range of 0. 01-1. 0 mg· ml-1(r=0. 9990). The detection limit was 1. 78 μg·ml-1 and the average recovery was 99. 1% (RSD=2. 7%, n=9). Conclu-sion:The method is simple and accurate, and suitable for the determination of thimerosal in chondroitin sulfate eye drops. Low-density polyethylene and polypropylene both show obvious adsorption of thimerosal,so chondroitin sulfate eye drops should not be packed in the above packing materials.

BACKGROUND:Magnesium alloy is a material that is easily degradable and has good mechanical properties.OBJECTIVE:To study the effects of the two kinds of magnesium aloy materials (AM50 and WE43) on proliferation and morphology of human umbilical vein endothelial cells.METHODS: Human umbilical vein endothelial cells at logarithmic phase were cultured in 100%, 50%, 10% extracts of AM50 and WE43 or directly seeded on the surface of AM50 and WE43 for 24 hours to study the morphological effect of magnesium alloys on the cells. Human umbilical vein endothelial cells cultured routinely served as negative controls. Relative growth rate of the cells was detected at 12, 24, 48 hours after culture. Cell morphology was observed using immunofluorescence staining at 24 hours after culture, and pH and element levels in the cell supernatant were measured.RESULTS AND CONCLUSION: (1) AM50 and WE43 extracts showed no effects on the proliferation of human umbilical vein endothelial cells in comparison with the negative control group. (2) Compared with the negative control group, reduced area of human umbilical vein endothelial cells was found on the surface of AM50 or WE43 alloy by the immunofluorescent staining, and the cytoskeleton of the cytoplasm was blurred. However, after 24 hours of culture, morphological changes of the cells cultured in 10%, 50% and 100% AM50 or WE43 extracts were consistent with those cultured routinely. The cytoskeleton of the cytoplasm was clearly visible. (3) Compared with the negative control group, the pH values of 100% AM50 and WE43 extract groups were significantly upregulated, and the level of magnesium element was also increased remarkably. In summary, AM50 and WE43 alloys possess good cytocompatibility with human umbilical vein endothelial cells, and have no influence on the cell proliferation and growth.

The human tissue kallikrein(KLK)gene family consists of 15 highly conservative serine pro-teases,which is the largest uninterrupted cluster of protease genes in the human genome. Several members of the family are expected to be markers for tumor diagnosis and prognosis. Studies find that the expressions of KLK2-11 and KLK13-15 are abnormal,and the majority of KLKs have potential diagnostic and prognostic values.

Methods: All medical professionals working in grassroots healthcare institutions in Pukou District, Nanjing City, were enrolled. The participants' demographic features and knowledge and practice of nosocomial infection control were collected using self-designed questionnaires and descriptively analyzed. Results: A total of 402 participants were enrolled, included 116 men ( 28.86% ) and 286 women ( 71.14% ). The respondents were predominantly at ages of 41 years and older ( 187 subjects, 46.52% ), with bachelor and above as the predominant educational level ( 200 subjects, 49.75% ) and intermediate title and above as the predominant professional title ( 168 subjects, 41.79%) , and there were 236 participants ( 58.71% ) with the length of service for more than 10 years. The awareness rate of nosocomial infection control knowledge was 56.22% among medical professionals working in grassroots healthcare institutions, with the highest awareness for COVID-19 prevention and control ( 89.55% ) and the lowest awareness for the key aspects in nosocomial infection control ( 39.55% ). The formation rate of implementing nosocomial infection control practices was 84.08%, with a low rate for “Implement satisfactorily the isolation interventions for patients with multidrug resistant bacteria” ( 71.14% ) and “Implement satisfactorily the control measures for nosocomial infections in key departments and key aspects”( 64.68% ). Conclusions Low levels are seen in the awareness of nosocomial infection control, behaviors of multidrug resistance management and key aspects in nosocomial infection control among medical professionals in grassroots healthcare institutions in Pukou District.

Objective To compare the efficacy of fixed bearing(FB) and rotating bearing(RB) in total knee arthroplasty (TKA) for knee valgus. Methods Data of 203 cases with valgus knee deformity who had undergone TKA procedure from January 2007 to December 2013 were retrospectively analyzed. 181 cases were primary joint replacement. They were divided into FB group and RB group. 168 patients (168 knees) were followed?up for more than 2 years. 83 cases (83 knees) were in FB group, and 85 cases (85knees) were in RB group. There were 57 males and 111 females, aged from 40 to 79 years, with an average age of 59.3 ± 7.2 years. Among them, 153 cases were osteoarthritis and 15 cases were rheumatoid arthritis. Activities of the knee , tibio?femoral angle on X?ray, Hospital for Special Surgery (Hospital for Special Surgery, HSS) knee score and the SF?36 scale scores were recorded before surgery and at the final follow?up. Results All patients were followed up for 24 to 84 months (average, 37.4 months). The average knee activities of the fixed bearing and rotating mobile bearing were from 72.8°±13.1°and 71.2°±12.8° be?fore surgery to 106.5°±9.8°and 115.4°±7.9° at final follow?up. The average tibiofemoral angle on X?ray decreased from 16.8°±5.3° and 15.2° ± 4.7° preoperatively to 5.6° ± 2.3 and 5.2° ± 2.1° at the final follow?up. The HSS knee score improved from 47.5 ± 7.1 points and 49.6±8.9 points to 89.1±4.6 points and 90.2±5.3 points at final follow?up. The SF?36 scale scores improved from 52.3± 15.4 points and 50.1±17.9 points to 81.6±12.3 points and 82.2±14.5 points at the final follow?up. At the latest follow?up, except the Range of motion, there were no statistically significant in any other indicator between two groups. Two cases appeared postoper?ative deep venous thrombosis symptoms. One case had joint stiffness early, and the symptoms improved after strengthen functional exercise. No infections, delayed knee instability, implant loosening or subsidence was found during the follow?up. Conclusion For patients with mild to moderate knee valgus, both fixed and rotating bearing with same soft tissue balance technique can improve the knee function and correct the valgus deformity, and the recent results are satisfactory.
