OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.

Objective To explore the clinical value of double contrast-enhanced ultrasonography (DCUS) on evaluation of the chemotherapy effect in advanced gastric carcinoma. Methods A total of 21 patients with unresectable and received chemotherapy of advanced gastric carcinoma were examined using ultrasound after taking oral contrast agent and bolus injection of Sono Vue, and findings of DCUS of each patient before and after chemotherapy were compared. Results The thickness of lesions was slightly thinner than that after chemotherapy,but there was no significant difference ( P ＞0. 05). In addition, there was no significant difference in the basal intensity (BI), peak intensity (PI), arrive time (AT) and time to peak (TTP) of gastric carcinoma tissues after chemotherapy (P ＞0.05). While the enhanced intensity (EI) value of gastric carcinoma tissues after chemotherapy was significantly less than that before chemotherapy (P ＜0.05). Conclusions The EI value in gastric carcinoma tissues may be considered as a sensitive and effective index in assessing the therapeutic effect of the chemotherapy in patients with advanced gastric carcinoma.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins in vitro, which results in the slower-growing research on the structure and function of membrane proteins and related ligand drugs than that of water-soluble proteins. Membrane protein stabilization technology is the premise of establishing high specificity, high sensitivity and high throughput drug screening methods for membrane protein ligands, which is of great significance. In this paper, some techniques for stable separation and purification of membrane proteins are reviewed, including detergents, artificial membranes, polymers, lentiviral particles and so on, as well as their specific applications in drug screening.

Liquid-phase microextraction is a novel pretreatment technique for biological samples developed on the basis of liquid-phase extraction technology, which is simple, rapid, economical, and environmentally friendly, and has been widely used in the analysis of biological matrix samples such as blood, urine, and saliva. In this paper, we review the basic principles of the main modes of liquid-phase microextraction techniques, i.e., single-drop microextraction, dispersive liquid-liquid microextraction, and hollow-fiber liquid-phase microextraction, and the progress of their applications in biological sample pretreatment by reviewing the literature in the past five years, with a view to providing technical support and reference for sample pretreatment in the fields of in vivo drug analysis, pharmacokinetic studies and new drug development.

ABC transporters on the intestinal barrier, blood-brain barrier and on tumor cells will affect drug bioavailability, transport across the blood-brain barrier and multidrug resistance. The active ingredients of traditional Chinese medicines can affect the function and expression of ABC transporters. When combined with pharmaceuticals the potential interaction between the two can change the efficacy of the medicines. We review the ABC transporter superfamily and their distribution with regard to their relationship and interactions with traditional Chinese medicine on the intestinal barrier and the blood-brain barrier, as well as their role in tumor multidrug resistance mediated by ABC transporters. We summarize the research progress over the past five years.

Objective To explore features and clinic values of LNR anatomy with multiple planar reconstruction techniques with 16-slice spiral CT at the same slice.Methods The lumbar vertebrae with normal adults of 55 cases and 23 cases with abnormal ENR caused by 8 cases with protrusion of lumbar disc, 5 cases with spinal stenosis,4 cases with malignant tumor,5 cases with trauma and 1 case with lumbar TB confirmed by operation were scanned with 16-slice spiral CT made in American GE company in routine posture of the lumbar vertebrae,reconstructed LNR with UNIX system in workstation (ADW 4.1),and analyzed their normal and abnormal anatomic manifestations at the same slice.Results All of LNR can symmetrically showed on oblique and coronal planes according to different segments:one segment from L1 to L5(55,100% ),two segments: from L1 to L2,L2 to L3 and L3 to L4(55,100% ),three segments: from L1 to L3 (49,88%),from L2to L4(46,84% )and from L3 to L5(20,36% ),four segments: from L1 to L4 (15,27% )and five segments:(8,15% ),respectively.Each LNR,including their whole shapes of passage from starting to end,direction,size,shape,tension and peripheral relationship and so on can showed clearly on oblique and coronal planes and on other planes. However,the later planes can increase LNR but decreasing numbers of LNR and especially increase very long one LNR reconstruction.Primary manifestation of all diseases can be showed on oppressing along its walking line,meanwhile,20 cases with adhesion, 14 cases with displacement,13 cases atrophy and 9 cases with increasing diameter.Conclusions Image anatomy features of full LNR with 16-slice spiral CT with the multiple plane reconstruction techniques is very ideal ways at the same slice.It is a very valuable way to make diagnosis and treatment of LNR diseases.The concept of"road sing"and showing"at the same slice"of LNR are tried to rise from in order to make foundation for studying their image.

OBJECTIVETo discuss the land surface temperature's effect on supervising the areas with snails, comparing the land surface temperature (LST) of the areas with snails with the LST of those without snails.

METHODSChoosing the lake areas of farmland in Jiangxi Province and the beach in the bank of Ganjiang, dividing into four areas according to snails. Picking up the normalized difference vegetation index (NDVI) and LST from the remote sensing data to find the difference between the areas with snails and the areas without snails, so as to illuminate the effects of the LST on distinguishing the areas with snails.

RESULTSThe NDVI of Dongfeng Wei (an area from farmland to lake) was 0 - 0.20, the NDVI of the areas with snails was 0.20 - 0.40. The NDVI of four areas is different (chi(2) = 104.69, P < 0.01). The LST of Dongfeng wei was 24 - 30 degrees C, Wuzhoutou without snails is 23 - 28 degrees C, Wuzhoutou with snails is 22 - 26 degrees C, Changjiangzhou was 20 - 24 degrees C. The LST of four areas is different (chi(2) = 115.23, P < 0.01). The analysis farther indicates the NDVI of areas without snails was lower than that of areas with snails, but the LST was higher.

CONCLUSIONThe NDVI and (or) the LST should be significantly different between the areas with snails and the areas without, it might be concluded that the LST should be a indication to some extent on judging whether some areas may be fit for snails.

OBJECTIVETo investigate the effect of Shen-Fu (SF) injection on gastrointestinal tract injury and its potential mechanism.

METHODSThirty-eight patients undergoing elective open heart surgery were assigned to Group C (control group, n=18) and Group SF (n=20) randomly. In Group SF, the patients received intravenous injection of SF (0.5 ml/kg) at the beginning of the surgery followed by a continuous infusion of 100 ml SF (1.0 ml/kg) solution diluted by saline at a rate of 0.004 ml x Kg(-1) x min(-1) with a Grasby pump. The control group was injected with normal saline in the same volume. Gastric intramucosal pH (pHi), activity of blood diamine oxidase (DAO), and concentrations of blood LPS and IL-6 were measured before CPB (S0) and 1 h (S1) and 2 h (S2) after aortic declamping, respectively.

RESULTSIn Group C, pHi value was significantly lower at S1 and S2 than at S0 (mean P<0.01) and blood DAO and concentrations of LPS and IL-6 were significantly higher at S1 and S2 than at S0 (mean P<0.01). In Group SF, pHi was obviously lower at S1 and S2 than at S0 (P<0.05) but LPS and IL-6 levels and DAO were higher at S0 (mean P<0.05). Blood DAO and LPS level demonstrated significant negative correlations with pHi (mean P<0.01) while LPS concentration showed a positive correlation with blood DAO (P<0.01) and IL-6 concentration (P<0.05). At S1 and S2 after aortic declamping, the levels of pHi were higher in Group SF than in Group C (mean P<0.01 ) but DAO and LPS and IL-6 levels were significantly lower in Group SF than in Group C (P<0.01).

CONCLUSIONSSF has a protective effect on gastrointestinal tract and can reduce inflammatory actions.

OBJECTIVETo observe the clinical effect of hemiplegic muscle spasticity treated with acupuncture on different acupoints in combination with rehabilitation.

METHODSNinety cases of post-stroke muscle spasticity were randomized into a corresponding and central axis acupuncture group (group A), a conventional acupuncture group (group B) and a rehabilitation group (group C), 30 cases in each one. In group A, the acupoints on the Governor Vessel were mainly selected, as well as those on Hand-Shaoyang meridian and Foot-Taiyang meridian. In group B, the conventional needling and rehabilitation training were applied in combination, of which, the acupoints were mainly from Hand and Foot-Yangming meridians, associated with the acupoints of Shaoyang meridian. In group C, only rehabilitation training was applied. The assessments according to modified Ashworth scale and CSS score were performed before treatment, after 2 weeks and 4 weeks treatment respectively.

RESULTSThe level of modified Ashworth scale of the flexor of elbow and wrist was reduced apparently after treatment in group A as compared with that before treatment (P < 0.01). The level of modified Ashworth scale of the flexor of elbow was reduced apparently after treatment in group C as compared with that before treatment (P < 0.05). There was significant difference on the level change in modified Ashworth scale for the flexor of elbow between group A and group C after 4 weeks treatment (P < 0.05). CSS score decreased significantly in group A as compared with that before treatment (P < 0.01), the improvement after treatment in group A was apparent as compared with the other two groups (P < 0.01).

CONCLUSIONThe corresponding and central axis acupuncture can improve muscle tone of hemiplegic limb, which is superior to the effect achieved by the conventional acupuncture in combination with rehabilitation training and the simple rehabilitation training.
