Objective: To observe the therapeutic effect of intracutaneous catgut embedding therapy on chronic injury of soft tissues. Methods: 106 cases of cervical spondylosis, myofascitis of back, lumbar muscle strain or the third lumbar vertebra transverse process syndrome were randomly divided into intracutaneous catgut embedding therapy group and acupuncture-cupping control group, 53 cases in each group. Their pain degrees. functional states and indurative cords were graded and comprehensive therapeutic effects were assessed. Results:There were very significant differences between the two groups in the observed indexes (P

Objective To provide the initiative experimental reference for resource utilization of Cynanchum komarovii by biological technology. Methods Using root, stem, and leaf of C. komarovii as explants, the proper media for inducing of callus were optimized by orthogonal test. In culturing process for proliferation of callus, the fresh and dry weights were determined at various times and callus growth curve was drawn. Meanwhile, division test of callus was taken. Results Root callus test showed the best effect in successful inducing percentage of 90%-100%. The best media combination of stem and leaf were MS+2,4-D 1.0 mg/L+6-BA 2.0 mg/L+NAA 0.5 mg/L and MS+2,4-D 0.5 mg/L+6-BA 0.5 mg/L+NAA 0.5 mg/L. The stem segament was more easily induced than leaf. The callus induced by various treatments is in loose character and fresh yellow colour with no brown phenomenon. At day 10 the growth entered the exponent period of callus offspring, the maximal fresh weight to 4.961 g and the dry weight to 0.496 g. The division rate of callus was rather low and not easy to shoot. However, the nail root was commonly seen in the test. Conclusion The root is proved to be the best explants in the test of inducing callus, which shows the best medium of stem and leaf for forming the callus. The growth of callus is bigger, but the division is not easy.

OBJECTIVE To evaluate the vali-dity and reliability of the outoral surface electrodes. METHODS The outoral surface electrodes were used to record the EMG activity of mandible muscles in 10 male OSAHS patients. The changes of EMG activity were observed among different sleep stages,during the apnea events,and which were compared with that recorded with intraoral surface electrodes from other researchers in our sleep center. The EMG activity was recorded again 7 days later with outoral surface electrodes in those 10 patients. RESULTS The characteristics of mandible muscular electrical activity in OSAHS patients by outoral surface electrodes were consistent to the characteristics of genioglossal electrical activity by intraoral surface electrodes. EMG activity was consistent between the 2 times recording results. CONCLUSION It is valid and reliable in measuring the EMG activity of mandible muscles by using outoral surface electrodes.

Objective To discuss the ultrasonic anatomy of gastrocnemius and its substructures in normal population. Methods Eighty gastrocnemius in 40 volunteers were scanned by real time high frequency ultrasound. Sonograms of medial and lateral heads of gastrocnemius were acquired. Plume angles between medial and lateral heads of gastrocnemius were measured at condition of rest, 5 kg and 10 kg isometric contraction. Both dominant and non-dominant legs were evaluated. Differences of plume angles were compared by ANOVA in different conditions and by t test in different legs. Results At the upper part of the muscle, both medial and lateral heads of gastrocnemius could be divided into muscular compartment, shallow compartment and deep compartment by hyperechoic intra-muscular septa with clear margin. The septa of lateral heads presented as hyperechoic side-lying′T′, while the septa of medial heads presented as hyperechoic side-lying-′T′. Vascular signals could be detected in these hyperechoic septa. The plume angle at the distal part of the lateral head of gastrocnemius was composed of shallow compartment attaching to the Achilles tendon, and that of the medial head was composed of medial muscular compartment attaching to the tendon. At rest, 5 kg and 10 kg isometric contraction, plume angles of lateral heads were (13.36±3.20)°, (13.32±3.30)° and (12.75±3.20)°, and plume angles of medial heads were (8.69±3.30)°, (8.59±2.99)° and (8.65±3.20)°. Under the same condition, plume angles of medial heads were larger than those of lateral heads and the difference was statistically signiifcant (t=9.09, 9.50 and 8.10, all P<0.01). Changes of plume angles between rest and different weight bearing conditions were small, and differences were not statistically signiifcant (F=0.89 and 0.02, P=0.41 and 0.98). Plume angles of medial heads in dominant legs and non-dominant legs were (13.66±3.60)° and (13.30±2.84)°, and those of lateral heads were (8.71±3.48)° and (8.80±3.35)°. The plume angles of medial heads were larger in dominant legs than those in non-dominant legs, while the plume angles of lateral heads were smaller in dominant legs than those in non-dominant legs. However, both differences were not statistically signiifcant (t=0.70 and 0.87, P=0.48 and 0.17). Conclusions The anatomical characteristics of medial and lateral heads and compartments of gastrocnemius can be clearly depicted by high frequency ultrasound. Plume angles can also be accurately measured.

AIM:To explore the survivorship and the mechanism of the intravenous administration of bone marrow stromal stem cells(BMSCs) for treating permanent focal cerebral ischemia in rats.METHODS:After purified,proliferated,and marked with BrdU,the BMSCs were injected intravenously into rats 1 d after focal cerebral ischemia.Modified neurological severity score(mNSS) was evaluated before and following 1,7,14 and 28 d after middle cerebral artery occlusion(MCAO).Rats were executed at 1,7,14 and 28 d after MCAO.Brain sections were stained with hematoxylin and eosin(HE) for determining the infarct volume.Slides were stained by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling(TUNEL) and immunostaining for cleaved caspase-3 method for apoptosis detection and mechanism exploration in situ.RESULTS:mNSS in BMSCs-transplanted group at 14th day and 28th day of MCAO was significantly lower than that in control group(P

Objective:To evaluate outcomes and differences of the equality indexes of health and health service utilization in different living standard indicators. Methods: Using multi-phase stratified random sampling to select samples of rural families in Ningxia region and collect data about sample families' income, consumption, wealth and some relevant data on family members' health status and health services utilization. Using concentration index to measure the equality of health and health services utilization with income, consumption or wealth index as living standard indicators respectively and discuss the differences of the outcomes. Results:For different living standard in-dicators, the correlation between each other was weak. The differences of concentration indexes with different living standard indicators between 0. 01 to 0. 21 , and most of whichweresignificant on the level of 0. 05. Conclusion: The impact of choice of living standard indicators on the equality index of health and health service utilization was signifi-cant. In a limited area, living standards measured by wealth index could be more accurate and objective than by in-come or consumption, but the condition of this method wasmore strict.
