OBJECTIVETo study and compare the therapeutic effects of electroacupuncture and probiotics combine Deanxit in treating diarrhea predominant irritable bowel syndrome (D-IBS).

METHODSTotally 64 D-IBS patients accompanied with anxiety and/or depression were randomly assigned to the Western medicine group (Group A) and the electroacupuncture (EA) group (Group B), 30 patients in Group A and 34 patients in Group B. Patients in Group A took Bacillus licheniformis and Deanxit, while those in Group B received EA. Four weeks consisted of one therapeutic course. Three-month follow-up was carried out. The scoring for the digestive tract symptoms, HAMA score, and HAMD score were evaluated before and after treatment. The recurrence in the 3-month follow-up was also observed.

RESULTSThe total effect rate was 86.67% in Group A and 88.24% in Group B with no statistical difference between the two groups (P > 0.05). There was statistical difference in the scoring for the digestive tract symptoms, HAMA score, and HAMD score (P < 0.05, P < 0.01). There was no statistical difference in the improvement of defecation frequency score, HAMA score, HAMD score between the two groups after treatment (P > 0.05). Better effects on improving abdominal pain score and abdominal distention score was obtained in Group B (P < 0.01), while better effects on improving the stool form score and mucus score were obtained in Group A (P < 0.01). There was no statistical difference in the recurrence rate between the two groups within the two-month follow-up (P > 0.05). The recurrence rate within the 3-month follow-up was obviously lower in Group B than in Group A (P < 0.05).

CONCLUSIONSEA and Western medicine (probiotics combined Deanxit) could effectively treat D-IBS patients accompanied with anxiety and/or depression. Both of them had different superiorities in improving symptoms. But EA had better long-term therapeutic effects.

Objective To compare the infectivity between laboratory adapted human inununodefi- ciency virus(HIV-1) and primary HIV-1 isolates for different mucosal epithelial cell lines. Methods Mu-cosal epithelial cells Caco-2, T-84, HeLa and lymphocyte MT-4 were infected with laboratory adapted HIV-1 SF33 and 2 primary HIV-1 isolates (02010561, 02010141). Culture supernatant and cells were collected respectively on 3-4 days interval after virus inoculation. The former was tested for HIV-1 antigen P24 level and viral load, and the latter was tested for total viral DNA and integrated viral DNA. Results All 3 virus strains could infect MT-4 cells and integrate into their genome. Only HIV-1 SF33 could infect Caco-2 cells but could not integrate into their genomic DNA. Both HIV-1 SF33 and 02010561 infected HeLa cells but only integration of HIV-1 SF33 was detected. All the 3 HIV-1 strains infected T-84 cells but only the integra-tion of HIV-1 SF33 and 02010141 was observed. Conclusion Although laboratory adapted and primary HIV-1 strains are able to infect human mucosal epithelial cell lines, transient or productive infection estab-lished in different mucosal epithelial cells is dependent on the character of cells and virus strains.

OBJECTIVETo compare the short-term clinical outcome between unilateral fixation fusion (ULF) and minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF) in treating lumbar disc herniation (LDH).

METHODSThe clinical data of 39 patients with LDH were retrospectively analyzed from June 2008 to March 2013. There was 22 males and 17 females, aged from 45 to 75 years old with an average of 56.9 years. Therer were 3 cases in L3,4, 15 cases in L4,5, 21 cases in L5S1. Among them, 21 patients underwent unilateral fixation fusion (ULF group) and 18 underwent minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF group). Operation time, blood loss, the times of radiographic exposure and hospital stay were noted and compared between two groups. Radiograph informations were regularily accessed and VAS, ODI scores were recorded at 3 days and 3, 6, 12 months after operation, respectively. According to modified Macnab criteria, the clinical effects were evaluated at final follow-up.

RESULTSAll operations were successful without severe complications. The averaged operative time and the times of radiographic exposure in ULF group [(95 ± 25) min and (4.2 ± 0.4) times] were less than that of MIS-TLIF group [(120 ± 35) min and (10.1 ± 3.9) times] (P < 0.05). But, the mean blood loss and hospital stay in MIS-TLIF group [(75 ± 45) ml and (7.2 ± 2.2)d ]were less than that of ULF group [(165 ± 60) ml and (11.0 ± 3.7) d] (P < 0.01). All patients were followed up from 12 to 45 months with an average of 29.5 months. The VAS and ODI score had significantly improved during the follow-up and no significant differences were found between two groups at the same time point (P > 0.05). The postoperative radiographs showed internal fixation position was good. And all patients obtained bone fusion by CT scan at 1 year after operation. There was no significant differences in modified Macnab criteria between two groups at the latest follow-up (P > 0.05).

CONCLUSIONFavorable short-term clinical effects can be achieved in suitable LDH patients with ULF or MIS-TLIF surgical procedures.

OBJECTIVETo explore the relationship between the -344T/C polymorphism of aldosterone synthase (CYP11B2) gene and essential hypertension in Chinese Mongolian population.

METHODSBy cluster-sampling method, a total of 1575 Mongolian people in Tongliao city of Inner Mongolia were included in this study. And 417 subjects were normotension, 596 subjects were prehypertension and 562 subjects were essential hypertension. A survey was conducted to collect data by personal interview using a standard questionnaire, meanwhile fasting blood samples were drawn. Height, weight, waist circumference, blood pressure, blood-fat indexes and fasting plasma glucose were measured. The variant genotypes of CYP11B2 were identified by PCR assays. The relationship between the -344T/C polymorphism of CYP11B2 gene and essential hypertension were analyzed by multinomial logistic regression model.

RESULTSCrude prevalence of prehypertension among Mongolian people was 37.84% (596/1575) and hypertension was 35.68% (562/1575). The age-standardized prevalence of prehypertension was 38.57% and hypertension was 31.53%. The frequency of the T and C allele was 0.66 (481/728) and 0.34 (247/728) for normotension group, 0.69 (696/1042) and 0.33 (346/1042) for prehypertension group, 0.71 (706/998) and 0.29 (292/998) for hypertension group. The multiple logistic models showed CYP11B2 variant genotypes were associated with prehypertension (TT/CC, OR = 1.33, 95%CI: 0.87 - 2.01; TC/CC, OR = 1.74, 95%CI: 1.13 - 2.67; TC + TT/CC, OR = 1.49, 95%CI: 1.01 - 2.22); CYP11B2 variant genotypes were associated with hypertension (TT/CC, OR = 1.70, 95%CI: 1.07 - 2.70; TC/CC, OR = 1.59, 95%CI: 0.98 - 2.50; TC + TT/CC, OR = 1.66, 95%CI: 1.06 - 2.58).

CONCLUSIONCYP11B2 gene -344T/C polymorphism were associated with essential hypertension in Chinese Mongolian population.

BACKGROUNDMany studies suggest that the gamma irradiation decreases allograft strength in a dose-dependent manner. However, no study has demonstrated that this decrease in strength translates into higher failure rate in meniscal allograft transplantation (MAT). The aim of this study was to investigate the effects of gamma irradiation on macroscopic and histological alterations of transplanted meniscal tissue and joint cartilage after MAT.

METHODSMedial total meniscectomies were performed on the right knees of 60 New Zealand white rabbits. All meniscal allografts were divided into three groups (20 in each group) and then sterilized with 0 Mrad, 1.5 Mrad, or 2.5 Mrad of gamma irradiation. For each group, 5 menisci were randomly chosen for scanning electron microscopic (SEM) analysis and the remaining 15 were prepared for MAT surgeries. Forty-five right knees received MAT surgeries (0 Mrad group, 1.5 Mrad group, 2.5 Mrad group, 15 in each group), whereas the remaining 15 only received medial meniscectomy (Meni group). The left knees of the Meni group were chosen as the Sham group (n = 15). All the rabbits were sacrificed at week 24 postoperatively. Cartilage of the medial compartment of each group was evaluated macroscopically using the International Cartilage Repair Society (ICRS) score and then histologically using the Mankin score based on the Masson Trichrome staining.

RESULTSThe SEM analysis confirmed that the meniscal collagen fibers would be significantly damaged as the dose of gamma irradiation increased. At week 24, the overall scores of macroscopic evaluations of the transplanted meniscal tissue showed no significant differences among the three groups receiving MAT surgeries, except for 2 in the 2.5 Mrad group presented partial radial tears at midbody. The ICRS scores and the Mankin scores showed the lowest in the Sham group and the highest in the Meni group (P < 0.05). For the three groups receiving MAT surgeries, the 2.5 Mrad group showed significant higher ICRS scores and Mankin scores than both the 0 Mrad group and the 1.5 Mrad group (P < 0.05). Whereas the 1.5 Mrad group presented similar results to the 0 Mrad group concerning both the ICRS scores and the Mankin scores.

CONCLUSIONSThe current in vivo animal study proved that although the meniscal collagen fibers were damaged after gamma irradiation, the failure rate of MAT surgeries might not significantly increase if the irradiation dose was <1.5 Mrad for New Zealand white rabbits.

To establish a co-culture system of nuclear transferred embryos in bovine, effects of co-culture cell types, passages and cryopreservation as well as addition of BFF or FBS were investigated. The results showed that embryos co-cultured with oviductal epithelial cell and granulosa cell achieved significantly higher blastocyst rate compared with the control group (P < 0.05) and co-cultured with oviductal epithelial cell had more embryo cell number than those with granulosa cell. Passages of co-culture cells significantly affected the blastocyst rate and embryo cell number (P < 0.05), and cryopreservation decreased the blastocyst rate and embryo cell number remarkably. Supplemention of BFF increased blastocyste rate significantly (P < 0.05). In conclusion, co-cultured with fresh primary oviductal epithelial cell along with addition of 10% BFF in SOFaa could improve development of nuclear transferred bovine embryo in vitro.
