OBJECTIVETo evaluate the efficacy and the relevant effect factors of acupuncture for type 2 diabetes mellitus (T2DM) in females.

METHODSOf 83 female patients of T2DM, 49 cases were deficiency of kidney yin syndrome and 34 cases were yin and yang deficiency syndrome. Acupuncture was adopted and the acupoints were selected according to the syndrome differentiation. In kidney yin deficiency syndrome, Taixi (KI 3), Shenmen (HT 7), Taichong (LR 3) and Sanyinjiao (SP 6), etc. were selected. In yin and yang deficiency syndrome, Shenshu (BL 23), Pishu (BL 20), Yishu (Extra) and Jingmen (GB 25), etc. were selected. In 3 courses of treatment, the changes in fasting plasma glucose (FPG), fasting insulin (FINS), insulin sensitivity index (ISI), insulin resistace index (Homa-IR), index of islet beta-cell function (Homa-beta), total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were compared before and after treatment between the two groups. The relationship of the efficacy was analyzed in terms of the syndrome differentiation, age, duration of sickness, obesity and hereditary factors.

RESULTSAfter the treatment, the levels of FPG, FINS, Homa-IR, TC, TG and LDL-C were reduced obviously (all P < 0.01) and the levels of ISI, Homa-beta and HDL-C were increased apparently (all P < 0.01). The total clinical effective rate was 80.7% (67/83), in which, that of kidney yin deficiency syndrome was 83.7% (41/49) and that of yin and yang deficiency syndrome was 76.5% (26/34). The efficacy was not different significantly between the two syndromes. But, the younger the age was, the better the efficacy was.

CONCLUSIONAcupuncture positively regulates the glucose and lipid metabolism in the patients of T2DM. This therapy improves insulin resistance, enhances the body sensitivity to insulin and improves insulin beta-cell function. The efficacy is related to the patient's age.

OBJECTIVETo study the expression of gastrin(GAS) and gastrin releasing peptide(GRP) in patients with gastric cancer and investigate the clinical significance.

METHODSThe expression of GAS and GRP in sixty patients with gastric cancer was detected by using tissue chip technique and immunohistochemical methods.

RESULTSThe positive rates of GAS and GRP were 30.0% and 11.7% respectively in 60 cases with gastric cancer. The positive rates of GAS and GRP were higher in moderately and poorly differentiated cancers than those in well differentiated cancer (P< 0.05). The positive rates of GAS and GRP were significantly higher in mucinous adenocarcinoma and signet-ring cell carcinoma than those in other types of gastric cancer (P< 0.05). The positive expression of GAS and GRP in gastric cancer was correlated with lymph node metastasis (P< 0.05).

CONCLUSIONTissue chip technique is a feasible,rapid,economic and accurate approach for screening clinical tissue specimens on a large scale.

Objective To investigate the value of Habib 4X in hepatic resection. Methods The clinical outcome of 21 patients with liver disease who received liver resection at the Tianjin Third Central Hospital from November 2009 to April 2010 were retrospectively evaluated. All the operations were carried out by using Habib 4X. Results All patients received hepatectomy, including right hepatectomy in three patients, left hepatectomy in one patient, multiple segmentectomy in nine patients, single segmentectomy in seven patients and partial liver resection in one patient. All tumors were reseeted completely. The mean operation time was (50±25) minutes and the mean blood loss was(129±117)ml. No patient was transferred to ICU. Three patients were complicated with bile leakage, one with lymphatic leakage and four with pleural effusion, and they were cured by non-surgical treatment. There were no patients with postoperative hemorrhage, incision infection or hepatic failure. No mortality was observed. The mean postoperative hospital stay was(19±14)days. Conclusions Radiofrequency energy was applied along the margins of the tumor to create zones of necrosis before resection with a scalpel, offering hepatobiliary surgeons an additional method for performing liver resections with minimal blood loss, low morbidity and mortality rates. As for malignant tumors, minor or major liver resection assisted by Habib 4X is safe, and it can reduce the chance of positive incisal margin.

With its abilities of trans-synaptic tracing and self-replication and wide host range, pseudorabies virus (PRV) has been applied in the field of neuroanatomy since the 1970s. Four decades of PRV application have made many advances in researches on neuronal tracing with PRV. Mechanism studies focused on investigating infection of primary neurons and tracing direction in secondary neurons, while application studies focused on development of new pathological strains and innovation of tracing techniques. To date, the mechanism and application of viral tracing are not completely figured out yet. Integration of molecular biology technology will improve the efficiency in related researches.

OBJECTIVETo observe the anti-inflammatory effect of total saponins of Panax japonicus on LPS-induced RAW264. 7 macrophages.

METHODThe effect of total saponins of P. japonicus of different concentrations on RAW264. 7 cell viability was determined with the MTT method. The NO kit assay was adopted to detect the NO release of total saponins of P. japonicus to LPS-induced RAW264. 7 cells. The enzyme linked immunosorbent assay (ELISA) was used to detect the secretion of tumor necrosis factor-alpha (TNF-alpha) and interleukin 1-beta (IL-1beta). The reverse transeriptase-polymerase chain reaction (RT-PCR) was used to determine the expression of inducible nitric oxide synthase (iNOS) ,TNF-alpha,IL-1beta. The protein expression of nuclear transcription factor-kappaB p65 (NF-kappaB p65) was tested by Western blot.

RESULTThe safe medication range of total saponins of P. japonicus was less than 80 mg x L(-1). Compared with the LPS model group, total saponins of P. japonicus high, middle and low dose groups (0.1, 1, 10, 40 mg x L(-1)) could significantly reduce the secretion of NO, TNF-alpha, IL-1beta of LPS-induced RAW264. 7 cells, and inhibit the expressions of iNOS, TNF-alpha and IL-1beta mRNA and the protein expression of NF-kappaB p65.

CONCLUSIONThis study preliminarily proves the protective effect of total saponins of P. japonicus on LPS-induced RAW264.7 macrophages. Its action mechanism may be related to NF-kappaB signal pathway.

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

OBJECTIVE: To analyze postmortem chemical changes in Landrace costal cartilages and ribs using attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, and to provide a novel technique for estimation of postmortem interval (PMI). METHODS: The swines were sacrificed by hemorrhage and their costal cartilages and ribs were kept in 20 degrees C. The chemical analysis of the costal cartilages and ribs were performed using ATR-FTIR every 72 h. The correlation between the certain spectral parameters and PMI was also analyzed. The time-dependent changes of costal cartilages were more significant than ribs. RESULTS: There were no obvious changes for the main absorbance bands position, and some absorbance band ratios showed time-dependent changes and significant correlations with the PMI. CONCLUSION ATR-FTIR has the ability to analyze postmortem chemical changes of the swine costal cartilages and ribs, and it can be a new method to estimate PMI based on spectroscopy.

BACKGROUNDIntersinus septal cell (ISSC) is not a very uncommon frontal recess cell. But it is poorly described in literature. The clinical significance of this anatomic variant still remains unclear. The purpose of this study was to clarify the anatomy, classification of ISSC and its clinical significance in Chinese subjects.

METHODSWe prospectively identified ISSC in 200 consecutive subjects who had undergone computed tomography (CT) scans: 120 without frontal sinusitis (group 1) and 80 with frontal sinusitis (group 2). The ISSC was classified into two types: Type I ISSC communicated with frontal sinuses, type II ISSC communicated with frontal recess. The patients of frontal sinusitis had undergone functional endoscopic sinus surgery with the assistance of the classification of ISSC. Statistical analysis was performed to correlate the ISSC and its type to the presence of frontal sinusitis.

RESULTSThe ISSC was obvious when reviewing the coronal and axial CT scans. Of the 200 CT scans reviewed, ISSC were present in 90 (45%). Of the 120 scans in group 1, ISSC were present in 49 (41%), among which type I ISSC was in 22 (18%) and type II was in 27 (23%). Of the 80 scans in group 2, ISSC was present in 41 (51%), among which type I ISSC was in 16 (20%) and type II was in 25 (31%). There were no statistically significant differences about the frequency distribution of total ISSC, type I and II ISSC between group 1 and group 2.

CONCLUSIONSThe prevalence of ISSC was very high in Chinese patients. The classification of ISSC was helpful for surgeon to operate according to whether it communicated with frontal sinus or frontal recess. The type II ISSC could be relatively easily removed from frontal recess.
