Objective To investigate the effects of bilateral sternocleidomastoideus contraction on neck flexion and extension. Methods The electromyograms (EMG) signals of left sternocleidomastoideus of 24 healthy persons were recorded respectively when neck relaxation and flexion in the supine position, and neck relaxation and extension in the prone position. The biomechanical measurement and analysis were done using anatomical specimens and models. Results The sternocleidomastoideus registered electrical resting potential when neck relaxation in the supine position, and when neck relaxation and extension in the prone position; the motor unit action potential of sternocleidomastoideus raised the type of mixed phase when neck flexion in the supine position. Conclusion The contractions of bilateral sternocleidomastoideus can lead to the head and neck flexion while neck joints are not fixed, and the contractions of bilateral sternocleidomastoideus can lead to the head extension under the state of fixing neck joints below atlanto-occipital.

OBJECTIVETo observe the effect of magnesium sulfate, Nifedipine Tablet (NT) combined Salvia Injection (SI) on endothelin-1 (ET-1), nitric oxide (NO), thromboxane A2(TXA2), prostacyclin I2(PG2), and hemorheology of preeclampsia patients.

METHODSTotally 704 preeclampsia patients were randomly assigned to the treatment group and the control group, 352 cases in each group. All patients were treated with magnesium sulfate combined NT (on the first day: slow intravenous injection of magnesium sulfate 5 g + intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg; on the second and third day, intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg), while those in the treatment group were dripped with SI additionally at 20 mL per day for 3 consecutive days. Before and after treatment plasma levels of endothelin-1 (ET-1), nitric oxide (NO), TXA2, PGi2, and hemorheology indicators [such as high blood viscosity (HBV), low blood viscosity (LBV), plasma viscosity (PV), erythrocyte rigidity index (ERI), fibrinogen (FIB)] of two groups were detected.

RESULTSCompared with the same group before treatment, serum levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the two groups after treatment (P <0. 05), but levels of NO and PG2 increased (P <0. 05). Compared with the control group in the same period, levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the treatment group after treatment (P <0. 05), but levels of NO and PGI2 increased (P <0. 05).

CONCLUSIONMagnesium sulfate, NT combined SI could effectively regulate the balance of ET-1/NO and TXA2/PGI2, and improve hemorheology of preeclampsia patients.

Objective To investigate the feasibility and clinical effectiveness of interventional ventricular septal defect(VSD) occlusion using asymmetric occluders in patients whose VSD are adjacent to aortic valves.Methods One hundred and fifty-two patients from our hospital whose VSD were occluded with asymmetric occluders were examined by echocardiography.Dimensions,shapes and shunts of VSD,structures around defects were observed and aortic valve prolapse(AVP) degrees were accessed before the interventions.The patients were followed up periodically after the procedures.The longest follow-up was 6 years.Results Sizes of VSD measured from left ventricular side were larger than those measured from right ventricular side.Twenty-seven cases with VSD had mild AVP.Right sides of defects had adhesions with variable morphological patterns in 85% patients with perimembranous VSD.After occlusion,there were 7 cases showed residual shunt,2 cases with the third degree atrio-ventricular blockages,3 cases appeared aortic-valve regurgitations (AR) and 1 case with slightly increased AR.Conclusions Immediate and medium-term effects of interventional occlusion with asymmetric occluders were satisfactory in the patients with VSD and mild AVP whose aortic valve margin were insufficient to symmetric occluders.Surgical operation should be preferred to patients with VSD and moderate to severe AVP and to very young children.Pre-closure echocardiographic evaluation is critical to the success of interventional closure with asymmetric occluder and the long-term out coming.

OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.

OBJECTIVETo study the effects of Chinese materia medica (CMM) combined chemotherapy on the recurrence, metastasis, and the disease free survival (DFS) of stage II and III colorectal cancer (CC) patients after radical cure.

METHODSRecruited were 366 inpatients and outpatients with stage II and III colorectal cancer (CC) from Changhai Hospital, Second Military Medical University, and Tumor Department of Longhua Hospital, Shanghai University of Traditional Chinese Medicine from January 2002 to December 2008. A non-randomized concurrent control method was adopted. Patients were assigned to the combination group (treated by CMM + chemotherapy, 189 cases) and the chemotherapy group (177 cases) according to whether they were willing to receive the CMM treatment for more than 6 successive months. By using follow-ups at clinics, by letter, and by telephone, the DFS, 1-, 2-, 3-, and 5-year DFS ratios were observed. The correlations between DFS and the gender, age, tumor location, staging of clinical pathology, pathological type, chemotherapeutic cycle, radiotherapy, CMM treatment, end point event (recurrence and metastasis) were analyzed.

RESULTSThe recurrence or metastasis occurred in 145 cases (39. 61%) of the 366 patients. Of them, local recurrence occurred in 17 cases (11.72%), liver metastasis in 45 cases (31.03%), lung metastasis in 52 cases (35.86%), and metastasis in other parts in 53 cases (36.55%). Results of one-factor analysis showed six factors such as the tumor location, pathological type, staging of clinical pathology, chemotherapeutic cycle, radiotherapy, and CMM treatment were correlated with the DFS, showing statistical difference (P<0.01, P<0.05). Results of multifactor analysis showed staging of clinical pathology, chemotherapeutic cycle, and CMM treatment were correlated with the DFS, showing statistical difference (P<0.01). Results of stratified study on the staging of clinical pathology indicated that the primary tumor location (P=0.016) and the pathological type (P=0.047) were the independent predictors for DFS of stage II CC. The median DFS of the two groups could not be calculated. Results of stratified study on the stages of clinical pathology indicated that CMM treatment (P=0.000) and chemotherapeutic cycle (P=0.017) were independent predictors for DFS of stage III CC. As for comparing the composition ratio of the two therapeutic cycles, results showed the baselines of the chemotherapeutic cycle of the two groups were balanced. Further comparison showed the median DFS for the chemotherapy group at stage III was 24. 16 months, while it could not be calculated in the combination group. The DFS, 1-, 2-, 3-, and 5-year DFS ratios were 92%, 72%, 61%, and 59%, respectively in the stage III CC combination group, while they were 74%, 50%, 36%, and 20%, respectively in the stage IlI CC chemotherapy group.

CONCLUSIONCMM combined chemotherapy could prolong the DFS of stage III CC patients after radical cure.
