Objective To clear the clinical efficacy of using early rehabilitation nursing model in the course of clinical nursing in patients with cerebral infarction.Methods Divided 60 patients with cerebral infarction into the observation group (30 cases) and the control group (30 cases) randomly,traditional nursing measures were used in the control group,the early rehabilitation nursing model was used in the observation group in addition.Compared the clinical efficacy,ADL scores,NIHSS scores and the satisfaction between the two groups.Results In the observation group,the satisfaction was 93.33％ (28/30),the efficiency was 90.00％(27/30),which were significantly higher than those in the control group [76.67％(23/30),[66.67％(20/30)].The ADL and NIHSS scores in the observation group was (91.25±11.38) and (8.01±1.05) respectively,which were significantly different with those of in the control group,the ADL and NIHSS scores was (79.37±10.27) and (10.22±1.27) respectively in the control group.Conclusions Early rehabilitation nursing model can effectively improve the never function of patients with cerebral infarction,and then improve their quality of life.

OBJECTIVETo observe the clinical efficacy on constipation predominant irritable bowel syndrome (IBS-C) treated with acupuncture for regulating the mind and strengthening the spleen and the impacts on the quality of life in the patients.

METHODSSixty patients of IBS-C were randomized into two groups. In the acupuncture group (30 cases), acupuncture was applied to Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Taichong (LR 3), Sanyinjiao (SP 6), Yintang (GV 29) and Baihui (GV 20), once a day, 5 treatments a week and 4 weeks treatment as one session. In the western medication group (30 cases), lactulose oral solution was prescribed, 15 mL each time, three times a day, 4 weeks treatment as one session. The symptom grade scale and the quality of life scale (IBS-QOL) were adopted to observe the changes in clinical symptoms and quality of life before treatment, after treatment and 2-month follow-up after treatment in the patients of the two groups separately.

RESULTS(1) Clinical symptom score: the difference in the symptom score at each time point was significant statistically in intra-group comparison (P < 0.01). In 1 week, 4 weeks of treatment and 2 months after treatment, the clinical symptom scores in the acupuncture group were lower than those in the western medication group (P < 0.05, P < 0.01). (2) IBS-QOL score after treatment was improved as compared with that before treatment in the two groups (P < 0.01). The improvement of IBS-QOL at 2 months after treatment in the acupuncture group was apparently superior to the western medication group (P < 0.05). (3) The total effective rate was 90.0% (27/30) in the acupuncture group and was 83.3% (25/30) in the western medication group. The overall efficacy in the acupuncture group was better than that in the western medication group (P < 0.01).

CONCLUSIONAcupuncture for regulating the mind and strengthening the spleen significantly relieves the clinical symptoms of IBS-C and improves QOL of patients. The total efficacy is superior to lactulose oral solution and presents a certain of long-term efficacy.

Objective To investigate the relationship between the general osteoporosis and local bone erosion in patients with rheumatoid arthritis (RA).Methods Bone mineral density (BMD) of femur (femur neck,Ward area,greater trochanter) and lumbar spine 2-4 (L2-4) by dual energy X-ray absorptiometry was measured in 120 patients with RA and 120 normal controls.All the clinical and laboratory factors of RA were recorded in details,and the radiographic changes in both hands of 76 RA patients were assessed by Sharp'method.Statistical anylysis was carried out by using t test and x2 test.Results ① Compared with normal controls,the BMD of total femur,L2,L3,L4 and L2-4 decreased significantly (P＜0.01),while there was no significant differences in the BMD of femur neck,Ward area and greater trochanter between the two groups (P＞0.05).② The incidence of osteoporosis in RA (34.2％) was higher than that in normal controls (15.0％)(x2=11.889,P=0.001).③ Patients with osteoporosis had elder age,higher scores of HAQ,higher scores of space narrowing and bone erosion of joint by X-ray' Sharp method than those of patients without osteoporosis.There were no significant differences in the changes of other clinical and laboratory parameters between the two groups(P＞0.05).④ BMD of total femur,femur neck,Ward area,greater trochanter,L2,L3,L4 correlated with Sharp scores in RA and had shown a negative correlations(P＜0.05).Logistic regression analysis showed that age(OR=1.069,P=0.012,95％CI:1.015-1.125) and Sharp scores(OR=1.022,P=0.003,95％CI:1.007-1.037) were risk factors for osteoporosis in RA patients,but treating with DMARD (OR=0.172,P=0.041,95％CI:0.032-0.930) was a protective factor for osteoporosis in patients with RA.Conclusion The BMD decreases significantly and correlates with age and local bone erosion in patients with RA,while the incidence of osteoporsis increases remarkably.

Objective To investigate the relationship between single-nucleotide polymorphism (SNP)in receptor activator for nuclear factor-κB ligand (RANKL),osteoprotegerin (OPG) gene and rheumatoid arthritis (RA).Methods In our study,3 SNPs in the genes of OPG (2 SNP:rs2073618,rs3102735) and RANKL (1 SNP:rs2277438) by ligase detection reactions from 200 RA and 201 controls were examined.BMD values of different areas were assessed using dual-energy X-ray absorptiometry.Clinical and laboratory parameters were collected.Analysis of variance,t-test and x2 test were used for statistical analysis.Results No signi-ficant differences in the distribution of the alleles and genotypes were observed between case group and the control group (P＞0.05).The haplotype analysis for RANKL and OPG SNPs showed that the rs2073618/rs2277438/rs3102735 GGG haplotype could reduce the risk of RA (1.5％ vs 6.0％,P=0.008; OR 0.216;95％CI:0.081 to 0.575) and the GAG haplotype increased the risk of RA (14.5％ vs 8.4％,P=0.007; OR 1.862,95％CI:1.179 to 2.943).Patients with RANKL-rs2277438 AA or GG genotypes (n=6) had significantly higher BMD values compared to those with AG genotypes (n=39) at spine lumber 3 (1.05±0.22 vs 0.93±0.26,t=2.314,P=0.023),spine lumber 4 (1.06±0.24 vs 0.94±0.28,t=2.27,P=0.030),spine lumber 2-4 (1.04±0.21 vs 0.89±0.28,t=2.788,P=0.007).The tender joint counts (13±7 vs 10±6),tender joint index (19±11 vs 13±9),and VAS score (5.7±1.9 vs 4.8±1.8) differed significantly between patients with the OPG-rs2073618 CC or GG genotypes (n=60) and GC genotypes (n=40).Conclusion The rs2073618/rs2277438/rs3102735GGG haplotype may be protective against RA,while GAG haplotype may increase the susceptibility to RA.RANKL gene SNP rs2277438 may affect BMD value at spine lumber,and OPG gene SNP rs2073618 may influence the disease activity of RA patients.

Objective To summarize the diagnosis and surgical treatment of hepatic focal nodular hyperplasia (FNH). Methods The clinical data of 63 patients with FNH proved by pathology were analyzed retrospectively. Results The disease mainly affected young to middle aged, 50 cases (79. 4% )were of 31-50 years old. Male and female ratio was 2.94: 1. Fifty-six patients (89%) were asymptomatic, 3 cases were HBsAg positive (4.8%). Liver function was basically normal (92. 1%),5 cases (7.9%) were with elevated level of total bilirubin and rGT. AFP, CEA and CA19-9 was all negative. FNH occured as a single node in 95.2% cases, ranging from 1.5 cm to 17 cm in diameter ( average 4. 5 cm). Of these patients, 25 lesions were present in the left lobe, 29 in the right lobe, 6 in the mid lobe, and 3 in the caudate lobe. A big central artery was found in 2 cases (3. 2% ) as found by color Doppler ultrasound. CT scan showed transient immediate enhancement in 96. 8% (61/63) of patients, with central scar in 6 cases. MRI demonstrated early vigorous enhancement in 93. 7% (59/63) of patients, with central scar in 5 cases. All patients underwent surgical resection; including local resection in 34 cases;segmentectomy or hepatectomy in 13 cases; hemihepatectomy in 13 cases. There was no postoperative mortality and major complications. Conclusions FNH is a kind of hepatic benign disease and characteristic of high preoperative misdiagnosis rate (25. 4% ).

AIM: To investigate the effects of transient receptor potential channel 6 (TRPC6) on the proliferation of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) induced by IL-1β.METHODS: The mRNA expression of TRPC6 in synovial tissues from RA or OA patients was studied by RT-qPCR.RA-FLS were cultured by enzyme digestion and tissue adhesion methods.The method of flow cytometry was applied to identify the RA-FLS.RA-FLS were treated with different concentrations (0, 0.25, 0.5, 1, 2, 4, 8 and 16 μg/L) of IL-1β for 36 h.The cell viability was examined by CCK-8 assay.RA-FLS were incubated with IL-1β (16 μg/L) for different time (12, 24, 36, 48, 60 and 72 h), and the cell viability was measured by CCK-8 assay.The interference efficiency of TRPC6-siRNA was determined by RT-qPCR and Western blotting.After incubation in the presence or absence of IL-1β medium, the cell viability, the percentage of EdU-positive cells and the percentage of (G2/M+S) phase were measured by CCK-8 assay, EdU labeling assay and flow cytometry, respectively.RESULTS: The mRNA expression of TRPC6 was found in synovial tissue with higher levels in RA patients than that in OA patients.TRPC6-siRNA significantly decreased the mRNA and protein expression of TRPC6 (P<0.05).When RA-FLS were treated with IL-1β, the proliferation of RA-FLS was increased (P<0.05).The differences of the cell viability, the percentage of EdU-positive cells and the (G2/M+S) phase percentage between TRPC6-siRNA group and blank control group or NC-siRNA group were significant, in the presence of IL-1β (P<0.05).However, they were not significant in the absence of IL-1β.CONCLUSION: TRPC6 is involved in the proliferation of RA-FLS induced by IL-1β.Silencing of TRPC6 gene inhibits the growth of RA-FLS induced by IL-1β.

Aim To investigate the effect of Ginsen-oside Rh2 on apoptosis in human colorectal cancer cell SW480,and to explore the possible mechanism of it. Methods The proliferation activity of SW480 treated with Ginsenoside Rh2 was measured CCK-8 assay.Ap-optosis rates were evaluated by FCM.Hoechst 33258 staining was used to observe cell nucleus morphologi-cal;change SW480 cells were treated with Ginsenoside Rh2,and the protein expressions of Bcl-2,Bax,p53, cleaved caspase-3 ,PI3 K,AKT,P-AKT,GSK-3β,P-GSK-3βwere detected by Western blot;SW480 cells were treated with LY294002,Rh2,LY294002+Rh2, the expressions of PI3 K,AKT,P-AKT,GSK-3β,P-GSK-3βwere detected by Western blot.Results The proliferation of SW480 cells was significantly inhibited by Ginsenoside Rh2 in dose-dependent and time-de-pendent manner.FCM showed the inducing apoptosis effect of Ginsenoside Rh2 was significantly different from that of control group.Hoechst 33258 staining in-dicated clearly cell apoptosis in Ginsenoside Rh2 treat-ment groups.Western blot showed Ginsenoside Rh2 decreased expression of Bcl-2,increased expression of Bax,p53 and cleaved caspase-3,PI3K/AKT/GSK-3βpathway proteins PI3 K,P-AKT,P-GSK-3βdecreased obviously,AKT and GSK-3βwere not changed signifi-cantly in SW480.SW480 cells were separately treated with LY294002,Rh2,LY294002 +Rh2,there were no significant difference in AKT and GSK-3βprotein a-mong all groups,and the expression of PI3 K,P-AKT, P-GSK-3βdecreased more obviously in LY294002 +Rh2 group compared with LY294002 and Rh2 alone. Conclusion Rh2 induces colorectal cancer cell apop-tosis through PI3 K/AKT/GSK-3βpathway,which ac-tivates p53 and cleaved caspase-3,and destroys the balance of Bcl-2/Bax.

Objective To investigate the diagnosi s and management of inflammatory abdominal mass after appendectomy. Methods Clinical data of 42 patients wit h inflammatory abdominal mass developing after appendectomy from 1972 to 2004 we re retrospectively analyzed. Results There were two kinds of mass: on abdominal wall (26 cases) and that within the abdominal cavity (16 cases). Diagnosis was established on clinical fi ndings and the barium enema examination. Correct preoperative diagnosis was achi eved in 30 cases, with 12 cases (28.6%) misdiagnosed. Laparotomy was performed in 29 cases. Postoperative pathology revealed inflammatory mass. All the 42 case s recovered from the illness. Conclusions Post-appendectomy abdominal mass is infrequent complication. T he clinical course is most often self-limited. However, laparotomy is indicated in patients when conservative therapy fails or there is a fear of malignancy or tuberculosis.

Objective To evaluate the effect of choledochoduodenostomy for the treatment of bile duct calculi. MethodsClinical data of 420 patients with choledochoduodenostomy from 1962 to 2002 were respectively analyzed. ResultsBefore 1982,this procedure was performed in 230 cases with postoperative cholangitis or sink syndrome found in 46 cases, and mortality in 6 cases. Since 1983,190 cases underwent large-sized choledochoduodenostomy with 7 cases suffering from postoperative cholangitis or sink syndrome and no mortality. The anastomotic stoma was less than 2.0 cm in 110 cases, between 2.0 to 2.5 cm in 184 cases, from 2.5 to 3.0 cm in 107 cases, no record in 19 cases. A total of 358 cases (85.2%) were followed up from 2 to 20 years. Result was excellent and good in 183 out of 190 cases(96.3%) after the year of 1983. ConclusionsCholedochoduodenostomy when the stoma was larger than 2.5 cm in diameter and was put low in position was effective for the prevention of recurrent cholangitis and sink syndrome for the treatment of bile duct calculi.
