Objective To explore the correlation between intestinal mucosal immune barrier and pathogenesis of pigment gallstone and its possible mechanism.Methods Eighty guinea pigs were randomly divided into control group(group CON),pigment gallstone group(group PS),and intestinal mucosal protection group(group GLN).The guinea pigs were fed with normal diet in group CON,pigment gallstonein during diet in group PS,and glutamine-supplemented diet in group GLN for 8 weeks.The guinea pig model of pigment gallstone was established.The incidence of pigment gallstone was detected.The morphology of intestinal mucosa was observed,and the numbers of CD3~+T cell,CD40~+B cell,and IgA~+ plasma cell were counted.Results The incidence of pigment gallstone was significantly higher in group PS than in groups GLN and CON(P＜0.05).Compared with group CON,the intestinal wall was significant thinner and represented obvious signs of inflammation in group PS,and the numbers of CD3~+ T cell,CD40~+ B cell,and IgA~+ plasma cell significantly decreased(CD3~+ T cell,21.8±2.5 vs 11.1±3.4,P＜0.01;CD 40~+B cell,12.9±2.0 vs 10.7±3.6,P＜0.01;IgA~+ plasma cell,12.4±3.4 vs 10.7±3.5,P＜0.01).The signs of inflammation were less severe in group GLN than in group PS.There were significant differences in the numbers of CD3~+ T cell,CD40~+ B cell,and IgA~+plasma cell between groups GLN and PS.Conclusion Intestinal barrier dysfunction,including mechanical barrier and immune barrier,is involved in the formation of pigment gallstone.Glutamine has proved to improve the function of intestinal mucosal barrier and decrease the incidence of pigment gallstone.

To observed the Clinical effect of ropivacaine (Rop) of different concentration used for analgesia of labor, and ex plore the ideal concentration and dosage. Methods: 45 case s of ASA Ⅰ-Ⅱ primiparae nearing labor were vandomly divided three groups rand omly (0.16% Rop group, 0.2% Rop group were assigned 15 cases). The analgesia, in which the cervical os had opened up to 2-3cm; the controlled group was not giv en the analgesia of labor. BP, SpO2, EKG, PETCO2, cerrical contraction , fetal cardiac sounds were monitored continuously in the perinatal analgesia pe riod. The analgesia effects were determined by giving a mark for pain by VAPS, motor nerve blockings were given amark by Bromage scale; Apgar scale were conduc ted 1-5 min after neonates were labored out. Results: The vital signs of three groups were stable in perinatal; the VAPS scale was lower s ignificantly in observed group than in controlled group; while the blocking freq uency and extent of motor nerve were highest from 0.2% Rop, which had light inhi bitory effect to cervical contraction, causing the dosage of oxytocin to increas e relatively; the NACS scale 24 h after labor was more increased significantly in observed group than controlled group. Conclusion: The un ique blockings to sense and motor were obviously separate, having no obvious eff ect to blood stream of uterus and placenta, being benificial to analgesia in per inatal. The 0.16% Rop was a more ideal local anaesthesia agent than 0.2% Rop .

Objective To explore the impact of juxtapapilary duodenal diverticulum on the formation of choledocholithiasis and biliary manometry after surgery.Methods The clinical data of 97 patients with common bile duct stones who successfully underwent ERCP and biliary manometry treatment from May 2011 to March 2014 were retrospectively analyzed.Ninty-seven common bile duct stone patients were divided to two groups,that is,52 cases of juxta-papilary duodenal diverticulum (experimental group) and 45 cases without juxta-papilary duodenal diverticulum (control group).The biliary manometric results before and after EST of both groups were compared.Results The basal pressure of sphincter Oddi of the experimental group before EST [(84.8 ± 26.1) mmHg] was higher than that of the control group before EST [(75.5 ± 14.6) mmHg] (P ＜ 0.05,1 mmHg =0.133 kPa);and that after EST was also higher than that of the control group after the operation[(19.8 ± 14.2)mmHg VS (15.9 ± 9.8)mmHg,P ＜ 0.05].The biliary pressure of common bile duct stone patients with JPD was higher than those without JPD before and after EST but with no significant difference(P ＞ 0.05).The biliary manometry was performed in 81 patients after one month and it was found that the basal pressure of sphincter Oddi of experimental group was still higher than that of the control group [(34.8 ± 17.1) mmHg VS (29.6 ± 15.3)mmHg,P ＜ 0.05].The biliary pressure of common bile of the experimental group was higher than that of the control group [(19.9 ± 11.2) mmHg VS (17.1 ± 13.1)mmHg,P ＜0.05].Conclusion The existence of juxtapapilary duodenal diverticulum increases the pressure of common bile duct and Oddi sphincter and leads to CBD stones.

Objective To discuss how to determine the operative margin in breast-conserving surgery in patient with early-stage breast cancer. Methods The breast-conserving surgery was performed on 111 patients with early-stage breast cancer who met the indication of breast-conserving. The operative incision was performed on normal breast tissue 1cm from the tumour edge and then the frozen sections of the surgical margin tissue were done to confirm that tumour was completely excised. The individualized therapy was performed according to pathologic examination and clinical stage. All patients were followed up regularly. Results 111 patients with early stage breast cancer received breast-conserving surgery and all had good curative effect except one patient had a local recurrence during the follow-up. Conclusions Operative incision on normal breast tissue 1cm from the tumour edge and frozen section of the surgical margin tissue are two crucial procedures to ensure the success of breast-conserving surgery and increase the life quality of patient with breast cancer.

Objective To characterize the image morphology and time-intensity curve of renal cell cancer and angiomyolipoma on contrast-enhanced harmonic sonography. Methods A total of 57 patients with 58 renal masses were enrolled in this study prospectively. The renal masses included 47 renal cell carcinomas (RCC) and 11 angiomyolipomas (AML). All patients were evaluated by tradi-tional gray-scale sonography, color Doppler sonography and contrast-enhanced harmonic sonography. Imaging findings and time-intensity curves of all renal masses were analyzed. The contrast-enhance-ment features between RCC and AML were analyzed. Results 57.4% of RCCs were hyperechoic masses and peripheral surrounding vessels and / or penetrating vessels were noted in 83.0% of RCCs on color Doppler sonography. 54.5 % of AMLs were hyperechoic masses while peripheral surrounding vessels and / or penetrating vessels were only noted in 27.3% of AMLs on color Doppler sonography. On contrast-enhanced harmonic sonography, hyper- or iso-enhancement were noted in 83.0% of RCCs, while hypo-enhancement were noted in 81.8% of AMLs (P<0.01). Statistically significant differences were noted between RCC and AML in the values of peak time (P=0.03), wash time (p= 0.02), peak intensity-basic intensity (P=0. 01), AT/R (△A tumor/△A renal) (P=0.00), k (P= 0.02), and Aok (P=0.02). Conclusions Contrast-enhanced sonography is useful in the differentia-tion of renal masses. Most RCCs are hyper- or iso-enhanced while most AMLs are hypo-enhanced. Time-intensity curves are helpful in differentiating RCC and AML.

Objective To investigate the effects of trimetazidine on the oxidative stress in maintenance he-modialysis (MHD) patients. Methods Eighty-six MHD patients and 30 healthy volunteers were recruited in the study. The activity of glutathione peroxidase (GSHPx) was measured by colorimetry and superoxide dismutase (SOD) in serum was measured by hydroxylamine method. The levels of serum malondialdehyde (MDA) were meas-ured by thiobarbituric acid reaction. Serum advanced oxidation protein products (AOPP) levels were measured by enzyme-linked immunosorbent assay (ELISA). All MHD patients were randomly divided into two groups, treatment group (n = 46) and control group (n = 40), who had undergone hemodialysis for at least three months before the study and were in a stable clinic status without signs of infection or disease activity. In the treatment group,20 mg of trimetazidine was taken orally three times each day for twenty-four weeks, when the parameters for oxidative stress were studied. The levels of GSHPx. SOD, MDA and AOPP in serum were measured before and after the treat-ment. Results At the initiation of the investigation, the serum levels of GSHPx [(584.37±215.70) μmol/L, (580.87±309.12) μmol/L vs (769.06±302.46) μmol/L] and SOD [(347.87±82.09) kU/L, (348.16±75.33) kU/L vs (428.34±15.23)kU/L] in the M HD patients were significantly lower than those in the normal eontrol group (P < 0.01), whereas the content of MDA [(4.94±1.32) nmol/L, (4.97±1.61) nmol/L vs (3.56±0.46)nmol/L] and AOPP [(120.95±59.24) μg/L,(121.76±69.12) μg/L vs (47.69±20.15) μg/L] in MHD patients was higher than those in the control group( P < 0.05 and P <0.01, respectively). After treatment for twelve weeks, the scores of GSHPx and SOD were significantly increased in the treatment group compared to that before treatment (P <0.01). However, the contents of the MDA and AOPP decreased. There were significant differences in the levels of GSHPx, SOD,MDA and AOPP between the two groups of MHD patients after the treatment with trim-etazidine. Conclusions Trimetazidine in maintenance hemodialysis patients appears to be associated with an im-provement of oxidative stress.

This study was aimed to evaluate effects of traditional Chinese medicine ( TCM ) five elements music therapy on the quality of life for both senior and non-senior advanced cancer patients , and improve TCM com-prehensive treatment mode . A total of 170 patients were stratified according to 70-year-old in a randomized controlled trial ( RCT ) with a parallel single-blind design . The ratio of patients among three groups was 2:2:1 . In the experimental group , TCM five elements music was given in the treatment . In the positive control group , western music was used in the treatment . And in the negative control group , no music was given in the treat-ment . The treatment was given for 30 min , 5 times per week . And the observation duration was 3 weeks . The Hospice Quality of Life Index-Revised ( HQOLI-R ) , Karnofsky Performance Scale ( KPS ) and Symptom Diary Score recorded by patients were used in the evaluation . The results showed that when comparing HQOLI-R , KPS and Symptom Diary Score before and after treatment among all advanced cancer patients in each group , there was a significant difference before and after treatment in the TCM five elements music therapy group ( P< 0 . 05 ) . But there was no significant difference before and after treatment in the western music therapy group or the negative control group ( P > 0 . 05 ) . It was concluded that TCM five elements music therapy is effective in improving quality of life and subjective symptoms for both senior and non-senior advanced cancer patients . However , the sensitivity of using the Symptom Diary Score as an evaluation index among senior patients still needs to be further proved .
