To study the role of a novel MDR-related gene MGr1-Ag in the multidrug resistant (MDR) gastric cancer. The whole length MGr1-Ag gene was cloned, and eukaryotic vectors carrying the full length of MGr1-Ag cDNA and its antisense expression vector were constructed. The sense vector and anti-sense were then transfected into MGC803 cells and SGC7901/VCR cells respectively by lipofectamine. The result showed that a 1.0kb fragment was successfully amplified by RT-PCR and cloned into pUCm-T vector. DNA sequencing suggested that the fragment was the properly encoded MGr1-Ag gene. Recombinant eukaryotic plasmids harboring MGr1-Ag and its antisense expression vector were also obtained by subcloning the gene into pCDNA3.1/V5-His, which was confirmed by endonuclease digestion. As confirmed by Western blot, stable cell strains with up and down-regulated MGr1-Ag expression were constructed. Those cell strains provided the basis for further study on the MGr1-Ag in MDR of gastric cancer.

Objective To explore the indication, to describe the key of operative technique in detail and to summarize the early results in mini-incision and minimally invasive surgery (MIS) total hip arthroplasty (THA) for hip disorders. Methods From Mar. 2003 to Mar. 2005, 43 patients (49 hips) were performed with MIS THA. The mean age of patients was 53.2 years ranging from 22 to 79 years. There were 22 males and 21 females. The average body mass index (BMI) was 23.4 ranging from 17.1 to 30.2. Using the modified postero-lateral approach, MIS THA was performed with cementless prostheses. For comparison, 35 patients (43 hips) were performed with standard THA at the same period. The age and BMI of patients in both groups were similar, but the pattern of disorders was different. The comparative items included preoperative bleeding, operative time, incisional length, postoperative functional recovery, and prosthetic position. Results 31 patients (MIS THA) and 25 patients (standard THA) were followed from 6 to 24 months (mean 13.1 months). No complications occurred in MIS THA. Dislocation appeared in one patient with standard THA at the two days after operation. The length of incision was 9.3 cm (range, 8.7 to 10.5 cm) in MIS group and 16.8 cm (range, 14 to 20 cm) in standard THA group. The difference was significant statistically (P

Objective To investigate the major clinical manifestations and their effect on prognosis in patients with posterior circulation stroke (PCS).Methods The clinical data of 129 consecutive hospitalized patients with acute PCS confirmed by clinical and imaging were registered prospectively,and they were followed up for 3 months.The patients were divided into a good prognosis group (modified Rankin scale [ mRS] score ≤ 2) and a poor prognosis group (mRS score ≥ 3) according to their mRS scores.Results 90.7％ patients had 4 to 12 symptoms and signs,only 1 presented an isolated symptom.The most common symptoms and signs were unilateral.Crossed paralysis (1.6％) or quadriplegia (0.8％ ) was rare.Univariate analysis showed that the symptoms of unilateral limb weakness (relative risk [RR] 1.262,95％ confidence interval [ CI] 1.030-1.546; P =0.030),slurred speech (RR 1.434,95％CI 1.133 - 1.816; P=0.004),dysphagia (RR 2.216,95％ CI 1.131 -4.341; P =0.017),and the signs of decreased unilateral muscle strength (RR 1.288,95％ CI1.047-1.583; P=0.021),central facial/tongue paralysis (RR 1.467,95％CI 1.164- 1.850; P=0.002),dysarthria (RR 1.468,95％CI 1.154- 1.867; P=0.002),ocular motor dysfunction (RR 3.073,95％CI1.346 - 7.017; P =0.005),and conscious disturbance (RR 5.736,95％ CI 1.268 - 25.946; P =0.023) were the risk factors for poor prognosis,while ataxia (RR O.478,95％ CI 0.284 -0.804; P =0.002) was associated with good prognosis.Multivariate logistic regression analysis demonstrated that after adjusted for all risk factors,the baseline National Institutes of Health Stroke Scale (NIHSS) (odds ratio [ OR] 1.513,95％ CI1.107-2.066; P=0.009),dysarthria (OR,7.11,95％ CI 1.207-41.877; P=0.030),ocular motor dysfunction (OR 8.653,95％ CI 1.230- 60.887; P=0.030),and large-artery atherosclerotic stroke (OR5.482,95％ CI 1.008 -29.803; P =0.049) were the independent risk factors for poor prognosis in patients with PCS,while ataxia (OR 0.251,95％ CI 0.067- 0.941; P=0.040) was independently associated with good prognosis of the patients.Conclusions The clinical manifestations in patients with PCS are complex,the majority of their symptoms and signs are unilateral.Most of the patients showed a variety of symptoms,and the isolated symptoms axe rare.Some symptoms and signs may indicate the prognosis of patients.

Objective:To observe the effect of chest pain center management model and emergency green channel on pre-hospital rescue rate of patients with acute ST-segment elevation myocardial infarction (STEMI).Methods:Patients with STEMI admitted in Yunnan Provincial Emergency Center between January 2017 and June 2019 were selected as the study subjects. 522 patients with STEMI sent by emergency center were included in the observation group (chest pain center management model of first-aid), while 326 patients with STEMI who came to the hospital by themselves were included in the control group (emergency green channel for first-aid). The pre-hospital and nosocomial first-aid related indexes, cardiac function (assessed by Killip grade), rescue rate, hospital stay and incidence of complications were compared between the two groups.Results:The response time of visit, time of initial electrocardiogram (ECG) completion and total time of first-aid in observation group [(1.04±0.11)min, (1.56±0.25)min, (10.63±2.26)min] were significantly shorter than those in control group [(2.82±0.26)min, (5.99±1.06)min, (18.65±2.98)min, P<0.05]. The grade of cardiac function in observation group was significantly better than that in control group ( P<0.05). Compared with the control group, the observation group had higher successful rescue rate, shorter hospital stay , lower total incidence of complications [94.25% vs 42.02%, (6.09±1.02)d vs (8.92±1.65)d, 13.01% vs 32.12%, P<0.05]. Conclusions:Compared with emergency green channel, chest pain center management model can not only shorten first-aid related time of STEMI patients, but also improve their successful rescue rate, reduce incidence of complications and improve prognosis.
