OBJECTIVETo compare the difference in the clinical efficacy on premature ovarian failure (POF) between the acupoint catgut implantation combined with artifical periodic therapy and the simple artificial periodic therapy and explore its effect mechanism.

METHODSSixty-five patients of POF were randomized into the two groups. In a western medication group, 32 cases were treated with the artificial periodic therapy with the oral administration of medroxyprogesterone acetate tablets. In a catgut implantation + western medication group, 33 cases were treated with the acupoint catgut implantation combined with artificial periodic therapy. The acupoints of Neiguan (PC 6), Zusanli (ST 36), Guanyuan (CV 4) and Sanyinjiao (SP 6) were selected. The treatment was lasted for half a year and the follow-up visit was for another half a year in the two groups. Kupperman index was used to assess the improvements in the clinical symptoms. The levels of serum sexual hormones such as follicle stimulating hormone (FSH) and estradiol (E2) were evaluated of the patients in the two groups before and after treatment. The efficacy was compared between the two groups.

RESULTSThe scores of the clinical symptoms were all significantly improved after treatment and in the follow-up in the two groups (P < 0.01, P < 0.05). In the 6-month follow-up visit after treatment, the result in the catgut implantation + western medication group was better than that in the western medication group (8.17 +/- 1.19 vs 13.68 +/- 1.08, P < 0.01). FSH was reduced after treatment in the two groups (all P < 0.01) and E2 was increased (all P < 0.05). The curative and remarkably effective rates were 75.8% (25/33) and 81.8% (27/22) after treatment and in the follow-up visit in the catgut implantation + western medication group, which were better than 67.9% (19/28) and 53.6% (15/28) in the western medication group separately (P < 0.05, P < 0.01).

CONCLUSIONThe acupoint catgut implantation combined with artificial periodic therapy achieve the remarkable improvements in the clinical symptoms of POF in the patients and the better results as compared with the simple western medication therapy. The combined therapys efficacy is stable and the long-term efficacy is apparently superior. The effect mechanism is related to the improvements in the serum sexual hormone levels.

OBJECTIVETo attempt to visualize the endolymph in patients with Meniere's disease by applying non-invasive intratympanic gadolinium through eustachian tube and three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI).

METHODSWith a 3 Tesla magnetic resonance imaging (MRI) unit, 3D-FLAIR imaging was performed 24 hours after intratympanic gadolinium through eustachian tube in two patients with medically active and intractable Meniere's disease. Pure tone test and tympanometry were performed 24 hours before and after the administration of gadolinium.

RESULTSThe gadolinium appeared in almost all parts of the perilymph inside the inner ear; moreover, the border between the perilymph and the endolymph was visible so endolymphatic space was clearly shown on 3D-FLAIR. No change in pure tone test and tympanometry was noted.

CONCLUSIONS3D-FLAIR MRI with intratympanic gadolinium through eustachian tube can clearly reveal the visualization of endolymph in patients with Meniere's disease. Intratympanic gadolinium therapy through eustachian tube is a safe and effective.

OBJECTIVETo study the molecular biological effects of Guilin Watermelon Frost (GWF) on the mRNA expressions of basic fibroblast growth factor (bFGF) in patients with uterine uterine cervical columnar ectopy.

METHODSOne hundred and sixty patients with uterine cervical columnar ectopy were assigned to two groups by the random digit table. Patients in the treatment group were treated with local spray of GWF, while those in the control group were local applied with bFGF-collagen sponge. The mRNA expressions of bFGF of the uterine tissue were detected in the two groups before and after treatment using RT-PCR.

RESULTSBefore treatment the mRNA expression of bFGF in the uterine cervical columnar ectopy was 0.55 +/- 0.10 in the treatment group and 0.58 +/- 0.13 in the control group, without insignificant difference (P > 0.05). After treatment it significantly increased in the two groups, being 0.82 +/- 0.17 and 0.78 +/- 0.15 respectively, showing statistical difference from before treatment (P < 0.01). But no statistical difference existed between the two groups after treatment (P > 0.05).

CONCLUSIONGWF showed enhancement on the mRNA expressions of bFGF in patients with uterine cervical columnar ectopy.

OBJECTIVE To identify the valid targets and new drugs of ulcerative colitis (UC), a recurrent and intractable inflammatory bowel disease. METHODS and RESULTS In an in vivo mouse model of DSS-induced colitis, HLJ2 decreased weight loss, colon contracture, disease activity index (DAI), colon mucosa damage index (CMDI) and histopathological index (HI). HLJ2 also decreased myelo?peroxidase(MPO) activity and reduced production of the inflammatory cytokines TNF- α, IL- 1β, andIL- 6. HLJ2 improved intestinal mucosa damage induced by dextran sodium sulfate (DSS) and increased the expression of ZO-1 and claudin-1. Fecal 16s rRNA high-throughput sequencing demon?strated a significant improvement in UC intestinal dysbacteriosis in mice treated with HLJ2, including increased abundance of probiotics such as Lachnospiraceae, Prevotellaceae, and Lactobacillaceae. At the same time there was a reduction in the abundance of pathogenic or conditional pathogenic microor?ganisms such as Bacteroidaceae, Porphyromonadaceae, Deferribacteraceae, and Pseudomonadaceae in HLJ2- treated mice compared with untreated mice. CONCLUSION Our results demonstrated that the XBP1 agonist HLJ2 inhibits inflammation, regulates the intestinal flora, and protects the intestinal mucosa. It is thus a potential therapeutic agent for ulcerative colitis.

OBJECTIVETo compare clinical outcomes of superior labrum from anterior to posterior (SLAP) repair and biceps tenodesis in treating type I SLAP injury.

METHODSFrom March 2009 to March 2012, 38 patients with type II SLAP injury were treated with SLAP repair and biceps tenodesis, and all patients were unilateral SLAP injury. Sixteen patients treated with biceps tenodesis included 8 males and 7 females with an average age of (49.3±3.7) years old (ranged, 45 to 54); 10 cases were on the left side and 6 cases on the right side; 10 cases were caused by falling down, 2 cases were caused by throwing damage and 4 cases were caused by daily life damage; the time from injury to operation were from 3 to 8 weeks. Twenty-two patients treated with SLAP repair included 14 males and 8 females with an average age of (49.0±2.8) years old (ranged, 44 to 56); 13 cases were on the left side and 9 cases were on the right side; 14 cases were caused by falling down, 5 cases were caused by throwing damage and 3 cases were caused by daily life damage; the time from injury to operation were from 3 to 7 weeks. Preoperative, postoperative at 6 months, 1 year and 2 years' UCLA and SST score were compared between two groups.

RESULTSThere was no significant differences in UCLA and SST score between two groups before operation. At 6 months after operation, UCLA and SST score in biceps tenodesis group was higher than SLAP group, and action,range of anteflexion, strength of anteflexion, degree of satisfaction in biceps tenodesis group was higher than SLAP group. There was no significant meaning in SST and UCLA score between two groups at 1 and 2 years after operation.

CONCLUSIONShort-term efficacy of biceps tenodesis for SLAP injury is better than SLAP repair, but long-term efficacy is fairly.

This study was aimed at exploring the immunophenotypic features of blasts in patients with myelodysplastic syndromes (MDS). Four-color flow cytometry using conventional and secondary gating strategies was used to immunophenotype blasts and the CD34 positive cells in bone marrow nucleated cells of 29 patients with MDS. The results showed: (1) with progression of MDS from RA/RAS, RAEB to RAEB-T, the proportion of CD34(+) cells were gradually increased from 8.0%, 46.4% to 76.8% (P < 0.05); (2) using CD45 vs SSC gating strategy, with the transformation of RA/RAS, RAEB to RAEB-T, the expression of HLA-DR, CD13, CD33, CD117 were also gradually increased (P < 0.05), and the expression of CD15 was gradually decreased (P < 0.05); (3) using CD45 vs CD34 gating strategy, the expression of HLA-DR, CD13, CD33, CD117 on blasts were higher by secondary gating method than those by conventional gating (P < 0.05). However, there were no significant difference (P > 0.05) in the expression of above-mentioned antigens on CD34(+) cells among different MDS subtypes. It is concluded that conventional gating method can reflect MDS progression from RA/RAS, RAEB to RAEB-T, and secondary gating strategy may accurately reflect the biological features of blasts in MDS. Abnormal expression of CD34 is related to the immaturity level and heterogeneity of blast cells, which is beneficial to the diagnosis of clinically suspected MDS incapable of diagnosing with morphology and cytogenetics.

OBJECTIVETo investigate the effects of different reference point on intra-abdominal pressure (IAP) measurement.

METHODSNine critically ill patients with risk of intra-abdominal hypertension (IAH) were studied from July 2008 to June 2010, all of the patients were equipped with abdominal cavity drain and urinary drainage tube. By which IAP was measured using direct and indirect methods respectively. The symphysis pubis, phlebostatic axis and the midaxillary line at the level of the iliac crest were defined as reference points. According to the different reference point, three sets of IAP measurements were obtained in the supine position with each method and kept as IAP(S), IAP(P), IAP(I). Bland-Altman method analysis and Pearson's correlation were performed to evaluate the relationships between results from different reference points with direct and indirect methods. Paired t-test was performed to evaluate the differences among different reference points.

RESULTSSixty measurements of IAP(S), IAP(P) and IAP(I) were obtained. In direct measurement through abdominal cavity drain, IAP(I) (13.8 ± 3.9) mmHg (1 mmHg = 0.133 kPa) was significantly higher than IAP(P) (12.8 ± 3.6) mmHg and IAP(S) (9.1 ± 3.6) mmHg, P < 0.05; while in indirect measurement through urinary drainage tube, IAP(I) (12.7 ± 3.2) mmHg was significantly higher than IAP(P) (11.7 ± 2.9) mmHg and IAP(S) (7.9 ± 3.0) mmHg too, P < 0.05. In either direct or indirect method, IAP(P) was higher than IAP(S), P < 0.05. And good correlations were found among IAP(S), IAP(P) and IAP(I).

CONCLUSIONSIn the supine position, pressure obtained via the bladder could reflect authentic IAP. But selection of reference point has great impact on IAP measurement.

OBJECTIVETo optimize the conditions of the vacuum belt drying process (VBD) for drying Panax notoginseng extract and compare with methods of vacuum freezing drying and spray drying.

METHODThe optimum conditions of VBD were obtained by orthogonal design and validated by determinations of moisture content of the dried product and recovery of active ingredients. Experiments on different drying methods were also conducted.

RESULT AND CONCLUSIONThe optimum conditions are as follows, the feeding speed was 15 mL x min(-1), the belt speed was 4 mm x min(-1), and the heating temperature was (105, 100 degrees C). Comparing with the drying methods of vacuum freezing drying and spray drying, vacuum belt drying possesses some advantages, such as higher recovery of active ingredients, less moisture content of dried product and better overall yield.
