OBJECTIVETo observe the effects of Tongfu Decoction (TFD) on the gastric emptying of normal rats, thus exploring whether it could promote gastric emptying rapidly.

METHODSThirty Sprague-Dawley (SD) rats were randomly divided into 3 groups, i.e., the normal control group, the domperidone group, and the TFD group, 10 in each group. They were respectively administered with normal saline, the domperidone suspension, and TFD by gastrogavage. Thirty min later the gastric emptying of mice was detected by single photon emission computed tomography technology (SPECT) labeled with 99m Tc-DTPA, and the gastric half-emptying time and the gastric emptying rate were calculated.

RESULTSThe gastric half-emptying time was (19.0 +/-1.7) min in the normal control group, (12.9 +/- 3.4) min in the domperidone group, and (12.7 +/- 4.1) min in the TFD group. Compared with the normal control group, the gastric half-emptying time was significantly shortened in the domperidone group and the TFD group (P <0.05). The gastric emptying rate at 15 min was 41.1% +/- 5. 8% in the normal control group, 52.9% +/- 10.9% in the domperidone group, and 56.0% +/- 10.3% in the TFD group, while at 30 min it was 65.6% +/- 2.8%, 72.9% +/- 2.6%, and 72.4% +/- 4.9%, respectively. Compared with the normal control group, the gastric emptying rate at 15 min and 30 min both significantly increased in the domperidone group and the TFD group (P <0.05). There was no statistical difference in the gastric half-emptying time or the gastric emptying rate between the two groups (P >0.05).

CONCLUSIONTFD showed similar effects as domperidone in rapidly promoting gastric emptying, and could shorten the gastric half-emptying time in normal rats.

A lot of experimental findings have confirmed that: Animal cells acquire a spherical shape just before the division; Under biochemical stimulus of mitotic apparatus aster the cells form a contractile ring in equator plane, and the mother cell divides into two daughter cells; meanwhile the total volume keeps constant. In Zinemanas and Nir's model the reorientation of microfilament and the visco-elasticity of cortex have been took into consideration. In our present work, the effective coefficient m due to biochemical stimulus was incorporated into the model, and the local distribution C was modified to diffuse with the plasma membrane motion. The numerical results showed that the formation of a contractile ring and parameters such as the surface tension in the furrow and internal pressure can be predicted successfully. Compared with Zinemanas and Nir's model, the results of our model are more correspondent with the experimental results. It can be concluded that the effective coefficient m has limited effects on the process control of cytokinesis.

OBJECTIVETo observe the clinical efficacy of electroacupuncture (EA) on mild cognitive impairment (MCI) for patients of Uygur and Han nationality and explore the national diversity among the patients with MCI.

METHODSTwenty-five cases were divided into Han nationality group (15 cases) and Uygur nationality group (10 cases) according to patient's nationality. In either group, EA was applied to Baihui (GV 20), Fengchi (GB 20), Xuanzhong (GB 39), Fuliu (KI 7), Sanyinjiao (SP 6) and Taixi (KI 3), once per day, 15 treatments made one session and there were 5 days at the interval among the sessions. Totally, 3 sessions of treatment were required. The proton magnetic resonance spectroscopy (1H-MRS) was used to observe the changes in the ratio of N-acetylaspartate and creatine (NAA/Cr) on the left hippocampus for the patients in two groups before and after treatment as well as the changes in the results of the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) separately.

RESULTSNAA/Cr in Uygur nationality group was higher than that in Han nationality group before treatment (1.659 +/- 0.418 vs 1.137 +/- 0.190, P < 0.05). After treatment, MMSE and MoCA scores all increased apparently as compared with those before treatment in two groups (P < 0.05, P < 0.01), and NAA/Cr on the left hippocampus in either group was up-regulated as compared with that before treatment (both P < 0.01).

CONCLUSIONEA can improve the overall cognitive function for the patients with MCI. There is the national diversity in the partial brain metabolite level between Uygur patients and Han patients with MCI.

OBJECTIVETo study the influence of clinical and pathological-morphological parameters on the prognosis of colorectal carcinoma.

METHODSUnivariate and multivariate Cox proportional hazard model were used to study the influence of clinical and pathological-morphological factors on the prognosis in 226 colorectal carcinoma cases.

RESULTSUsing univariate analysis, data showed that the factors significantly related to disease prognosis would include: the depth of direct spread, vessel invasion, perineural invasion, tumor budding, peritumoral-lymphocytic infiltration, Crohn-like reaction, number of positive lymph nodes, distant metastasis, TNM stage and urine glucose. Multivariate Cox proportional hazard model showed that six factors were identified to be associated with higher relative-risk (RR), including: older age, advanced TNM stage, more severe budding, perineural invasion, less peritumoral-lymphocytic infiltration and urine glucose.

CONCLUSIONAge, TNM stage, tumor budding, perineural invasive, peritumoral-lymphocytic infiltration and urine glucose were independent predictors to the prognosis of colorectal carcinoma.

The bodies found in water are one of the most common types in forensic practice. The dis-covery site of the body is often not the drowning site. However, the determination of drowning site is vital for the identification of victim. Inorganic particles and planktons, such as granular impurities, diatoms and bacteria, are valuable markers for the diagnosis of drowning. By comparing the granular impurities and planktons in tissues and suspicious drowning mediums, the drowning site can be concluded based on their similarity of types and distribution, which has practical applied value. In this paper, the research progress on determination of drowning site is summarized to provide reference for the peers.

OBJECTIVETo observe the clinical efficacy of Penyanqing Capsule (PYQC) in treating pelvic inflammation of Qi-stagnation with blood stasis syndrome.

METHODSThe randomized, single blinded, parallel positive drug controlled method was adopted, with 82 patients assigned into two groups by envelop method. The 42 patients in the treated group received PYQC 3 times a day, 4 capsules each time taken orally; the 40 patients in the control group were given orally Fuyankang tablets (FYKT) 3 times a day, 6 tablets each time. The therapeutic course for both groups was 2 months, and 2 courses of treatment were given successively to observe the comprehensive effect, changes of symptoms and signs before and after treatment. The effects of PYQC on hemorrheological character in part of the patients and on the pathogenetic chlamydia and mycoplasma were also observed.

RESULTSThe total effective rate in the treated group was 83.3%, which was insignificantly different from that in the control group (77.5%, P > 0.05). However, PYQC could significantly lower the hemorrheologic indexes in patients and showed definite influence on the pathogenetic chlamydia and mycoplasma.

CONCLUSIONPYQC has good therapeutic effect in treating chronic pelvic inflammation of Qi-stagnation with blood stasis syndrome, and showed definite effect on chlamydia and mycoplasma.

OBJECTIVESelecting variable-number tandem-repeat (VNTR) loci for different serogroups of Shigella spp to explore and establish multilocus variable-number tandem-repeat analysis (MLVA) method, in order to study the molecular characteristic of the isolated strains.

METHODSOf the Shigella strains found by dysentery surveillance in Beijing from 2001 to 2009, 180 strains were selected for this study, according to the number and serotypes of the surveillant strains, at the ratio of 15%; including 50 strains of Shigella sonnei and 130 strains of Shigella flexneri. After screening the polymorphism of the 18 VNTR loci, 10 VNTR loci (sh1-sh10) were retained and constructed three groups of multi-PCR methods to detect all he 180 strains and analyze MLVA molecular subtypes using capillary segments.

RESULTSA range of 2 to 11 alleles were found on the 10 VNTR loci among the 180 Shigella strains, with a diversity index value between 0.158 and 0.766. The 10 loci showed diversity in different serogroups, such as only one allele found in sh6 of Shigella flexneri, sh2 and sh3 of Shigella sonnei individually. The isolated 180 strains were divided into 84 MLVA subtypes, with a resolution ratio D value at 0.967 (95%CI: 0.956 - 0.978). The 130 strains of Shigella flexneri were divided into 63 subtypes, named as TF001-TF063; among which TF001, TF002 and TF 005 were the dominant subtypes, accounting to 17, 16 and 15 strains respectively. The 50 strains of Shigella sonnei were divided into 21 subtypes, named as TS001-TS021; among which TS002 (14 strains) and TS001 (7 strains) were the dominant subtypes.

CONCLUSIONMLVA subtyping method including 10 VNTR loci was preliminarily developed. The MLVA cluster analysis revealed that the subtypes of Shigella strains isolated in Beijing were diverse, and suggested the possibility of multiple-clone source.
