Objective:To study the expressions of Vascular Cell Adhesion Molecule 1 (VCAM-1) and Intercellular Adhesion Molecule 1 (iCAM-1) in patients with endometriosis and to explore its effect on the onset of endometriosis.Methods:VCAM-1 mRNA and ICAM-1 mRNA were detected by real-time PCR method in 15 specimens of eutopic endometrium and 15 specimens of ectopic endometrium from patients with endometriosis(EMT group)and 15 specimens of endometrium from patients without endometriosis(control group).VCAM-1 and ICAM-1 protein were detected by Western-Blot method.Soluble VCAM-1 and soluble ICAM-1 in 44 serum of patients with endometriosis(EMT group) and 28 serum of patients without endometriosis(control group) were tested by ELISA.Meanwhile the correlation of expressions of VCAM-1 and ICAM-1 were analyzed in different groups.Results:①The expressions of VCAM-1 mRNA and ICAM-1 mRNA in ectopic endometrium were significantly higher than those of eutopic endometrium and the controls(P ＜0.01).There was no significant different mRNA expression between eutopic group and control group(P＞0.05).②The protein expressions of VCAM-1 and ICAM-1 in eutopic group were significantly higher than those of ectopic group and the control group(P ＜0.01).The protein expression of VCAM-1 in eutopic group were higher than those in the controls group(P＜0.01).There was no significant different protein expression of ICAM-1 between eutopic group and the controls group(P ＞0.05).③The concentration of sVCAM-1 and sICAM-1 in serum from patients with EMT were significantly higher than those in the control group(P＜0.01).The concentration of slCAM-1 in serum from patients with EMT in stage Ⅲ-Ⅳ were significantly higher than those in stage Ⅰ-Ⅱ (P ＜ 0.01).④There was no significant correlation in the expression of mRNA,protein and serum between VCAM 1 and ICAM-1 in ectopic group and eutopic group(P ＞ 0.05).Conclusions:The abnormal expressions of VCAM-1 and ICAM-1 in ectopic endometrium may play an important role in the development of endometriosis.The signaling pathways and protein expression way may be different between VCAM 1 and ICAM 1 in endometriosis.

Objective To investigate the distribution of nail disorders in patients with a chief complaint of nail abnormalities. Methods From May 2007 to May 2010, patients who attended the dermatology outpatient clinic with a chief complaint of nail abnormalities were included in this study. Routine dermatological examination together with fungal culture, microscopic and pathological examination of affected nails was carried out to clarify the diagnosis of nail disorders. The results were statistically analyzed. Results Of the 2776 cases,onychomycosis accounted for 45.28% (1257), followed by paronychia (479, 17.26%) and psoriasis (122,4.39%). Conclusion In this region, patients with a chief complaint of nail disorders are most likely to suffer from nail infections.

Objective This study aims to explore the application value of tuberculosis T lymphocytes enzyme-linked immune SPOT test (T-SPOT.TB) on early diagnosis of tuberculosis.Methods The TB infection in 189 inpatients suspected tuberculosis in pneumology department of Shaanxi Provincial People's Hospital was detected with T-SPOT.TB,fluorescence RQPCR,tuberculosis (TB-Ab)protein chip and PPD methods.Results The sensitivity of four methods was 91.54％ (119/130),73.85％(96/130),63.08％(82/130) and 57.69％ (75/130) respectively and the specificity of those was 89.83％ (53/59),86.44％(51/59),67.79％(40/59) and 66.10％(39/59),respectively.The sensitivity of T-SPOT.TB method was statistically higher than those of other three tests,respectively (P＜0.05).The specificity of T-SPOT.TB was significantly higher than those of TB-AB and PPD (P＜0.05),but there was no statistical difference between RQ-PCR and T-SPOT.TB (P＞0.05).The positive predictive values of T-SPOT.TB,fluorescent quantitative PCR,TB-Ab and PPD assays were 95.2％ (119/1250),92.3％ (96/104),81.2％ (82/101) and 78.9％ (75/95) respectively while the negative predictive values of those were 82.8％ (53/64),60％ (51/85),45.5％ (40/88) and 41.5％ (39/94),respectively.The false-positive rates (misdiagnosis rate) of four assays were 10.2％ (6/59),13.6％ (8/59),32.2％ (19/59) and 33.9％ (20/59) respectively and the false-negative rates (rates of missed diagnosis) of those were 8.5％ (11/130),26.2％ (34/130),36.9％ (48/130)and 42.3 ％ (55/130),respectively.The negative likelihood ratios of T SPOT.TB,fluorescent quantitative PCR,TB-Ab and PPD assays were 0.11,0.16,0.48 and 0.51 respectively,meanwhile the positive likelihood ratios of T-SPOT.TB,fluorescent quantitative PCR,TB-Ab andPPD assays were 9.0,5.4,2.0 and 1.7,respectively.What' s more,the diagnostic accordance rates of the four assays were 91.0％ (172 189),77.8％ (147 189).64.6％ (122/189) and 60.3％ (114/189),respectively.Conclusion T-SPOT.TB test is a more sensitive and specific method and of great significance to the early diagnosis of TB,which has more clinical value in different stages of tuberculosis diagnosis.

Objective To investigate the influences of lysozyme on the mRNA expressions of MMP-1,-12 and lysyl oxidase(LOX)in cultured fibroblasts in vitro.Methods Primarily cultured fibroblasts isolated from human skin were treated with three concentrations(0.1×10~(-8),1×10~(-7)mol/L)of lysozyme followed by another 24-hour cuhure.Subsequently,total RNA was extracted from the fibroblasts and subjected to RT-PCR for the detection of MMP-1,-12 and LOX mRNA.Results There was a significant difference in the mRNA expressions of MMP-1,-12 and LOX among the fibroblasts treated with the three concentrations of lysozyme (F=6.98,4.44,5.24,respectively,all P<0.05).SNK-q test showed that untreated fibroblasts differed signifi-cantly from those treated with lysozyme of 1×10~(-7) mol/L in the mRNA expression of MMP-1 and MMP-12 (P<0.05),and from those treated with iysozyme of 1×10~(-7) mol/L.and 1×10~(-8)mol/L in the mRNA expres-sion of LOX(both P<0.05),whereas no significant difference was ohserved between fibroblasts treated with lysozyme of 1×10~(-8) mol/L and untreated fibrohlasts or those with lysozyme of 1 x 10~(-7)mol/L in the mRNA expression of MMP-1 and MMP-12.or between fibroblasts treated with lysozyme of 1 x 10~(-8)mol/L and those with that of 1×10~(-7) mol/L in the expression of LOX (all P>0.05).Conclusions Lysozyme upregulates the mRNA expression of MMP-1 and MMP-12 but downregulates the mRNA expression of LOX in cultured fibro-blasts in vitro.

Objective:To explore the use of internet-based continuous visual recognition task (MemTrax test, MTX) as a rapid screening tool for amnestic mild cognitive impairment (aMCI).Methods:Sixty-four patients with aMCI and 64 individuals with normal cognition as healthy controls were enrolled respectively from Department of Neurology and Health Examination Center of the First Affiliated Hospital of Kunming Medical University from August 2018 to December 2019. Montreal Cognitive Assessment (MoCA) scale and MTX were adopted to assess the cognitive function of all subjects. The total adjusted MoCA scale score, correct rate of MTX, reaction time of MTX and MTX score were obtained and statistically analyzed.Results:The adjusted MoCA scale scores of aMCI patients and healthy controls were 19 (14, 24) and 26 (24, 27; Z=6.795), the correct rate of MTX of aMCI patients and healthy controls were 74% (60%, 80%) and 88% (84%, 94%; Z=8.359), and the MTX score of aMCI patients and healthy controls were 51.11±14.07 and 70.56±14.91 ( t=7.590), respectively, all with statistically significant difference ( P<0.001). Reaction time of MTX of aMCI patients and healthy controls was 1.401 (1.253, 1.590) s and 1.277 (1.163, 1.410) s, respectively ( Z=3.083, P<0.01). After adjustment for age, physical or mental occupation, exercise, hypertension, hyperlipidemia, stroke, sleep time, as well as smoke, the linear regression showed that the aMCI patients had a significant decrease of adjusted MoCA score, correct rate of MTX and MTX score ( P<0.001), and an extension of reaction time of MTX ( P=0.071), compared with the controls. By MTX and MoCA scale assessment, the best cutoff value was 81% for correct rate of MTX and 23 for adjusted MoCA scale score respectively for the prediction of aMCI (with sensitivity of 79.7%, 93.8% respectively, and specificity of 68.8%, 82.8% respectively). The area under the curve (AUC) of correct rate of MTX was 0.93 (95% CI 0.89-0.97, P<0.001), and the AUC of adjusted MoCA score was 0.85 (95% CI 0.78-0.91, P<0.001). There was a statistically significant difference in paired comparison of the two AUCs (χ2=4.620, P<0.05). Conclusion:MTX acts better for the detection of aMCI than MoCA scale, and correct rate of MTX<81% can be considered as the existence of MCI.

The difficulty in the participant recruitment is the common question in acupuncture clinical trial study. The existing recruitment of clinical trial is most applicable for the clinical trial of medicines. Because the intervention of acupuncture clinical trial is different from that of medicines, characterized as the specialties in "theory, principle, acupoints, technique", it is very necessary to develop the strategy on the participant recruitment in acupuncture clinical trial. The free community medical consultation is one of the important means of recruitment. In the paper, by taking the participant recruitment of acupuncture clinical trial on chronic stable angina pectoris as the example, the discussion is given on the strategy on the recruitment of free community medical consultation in the aspects of feasible investigation of recruitment approach, recruitment plan, participant screening, etc. The revisiting after the free community medical consultation is the important approach to the improvement of successful recruitment. This strategy on the recruitment of free community medical consultation is highly practical and improves the successful rate and compliance of the participant recruitment. Hence, this strategy deserves to be promoted.

Objective: To compare the clinical efficacy of proximal gastrectomy with double tract reconstruction (PG-DT) and total gastrectomy with Roux-en-Y reconstruction (TG-RY) for proximal gastric cancer. Methods: The retrospective study was conducted. Clinicopathological data of 132 patients with proximal gastric cancer confirmed by pathology who underwent PG-DT (n=51) or TG-RY (n=81) by the same surgeon team in Southwest Hospital of Army Military Medical University between January 2006 and December 2016 were collected. Patients with preoperative neoadjuvant therapy, non-R0 resection and non-adenocarcinoma confirmed by pathology were excluded. Observation indicators included intraoperative (operation time and blood loss); postoperative (time to flatus, hospital stay, total complications, metastasis of lymph nodes around distal side of stomach from cases undergoing TG-RY), follow-up (long-term hemoglobin level, incidence of anemia, and survival) parameters. Survival analysis was conducted using the Kaplan-Meier method, and Log-rank test was used to compare survival difference between two groups. Results: No statistically significant differences were found between two groups in the baseline data, including age, gender, BMI, hemoglobin level before operation, postoperative TNM stage, tumor size and histological differentiation between two groups (all P>0.05). There were no significant differences between PG-DT and TG-RY in intraoperative blood loss [200 (200) ml vs. 200 (195) ml, Z=-1.860, P=0.063], time to flatus [(2.7±1.0) days vs. (2.6±1.1) days, t=0.225, P=0.823], postoperative hospital stay [10(3) days vs. 10 (4) days, Z=-0.449, P=0.654] and morbidity of perioperative complications [5.9% (3/51) vs. 8.6% (7/81), χ²=0.081, P=0.775]. Compared with the TG-RY group, PG-DT group had longer total operative time [294 (97) minutes vs. 255 (71) minutes, Z=–3.148, P=0.002]. The hemoglobin data of 42 patients with PG-DT and 56 patients with TG-RY were collected 1 year after operation. The incidence of anemia in PG-DT group was lower than that of TG-RY group [64.2%(27/42) vs. 82.1% (46/56), χ²=4.072, P=0.045], and PG-DT group had higher level of hemoglobin than TG-RY group [(114.4±16.3) g/L vs. (106.6±15.0) g/L, t=2.435, P=0.017]. There were 4 cases (4/81, 4.9%) with metastasis of lymph nodes around distal side of stomach in TG-RY group. All of these 4 tumors were T4 in depth and were more than 5 cm in diameter. The median follow-up period was 26 (1 to 110) months. One-year, 3-year and 5-year survival rates were 93.2%, 65.3% and 55.0% in PG-DT group, and 85.8%, 63.8% and 47.2% in TG-RY group, respectively without significant difference (χ²=0.890, P=0.345). Conclusions Compared with TG-RY, PG-DT has the same safety and feasibility for proximal gastric cancer. Although the operative time is a little longer than TG-RY, PG-DT has advantages in improving the postoperative hemoglobin level.
