Objective:To observe the effect of point-toward-point needling at points on the low back regions on residual back pain after percutaneous kyphoplasty (PKP),thoracolumbar function and quality of life (QOL) in patients with osteoporotic vertebral compression fracture (OVCF).Methods:A total of 72 patients with OVCF and residual back pain after PKP were included and allocated into a treatment group (n=36) and a control group (n=36) by the random number table.Cases in the control group received salmon calcitonin injection (miacalcic),for 1 mL each time,once a day,and oral intake of calcium carbonate D3 pill,600 mg each time,once a day,whereas cases in the treatment group received point-toward-point needling at points on the low back regions and electroacupuncture (EA) for 30 min each time,once a day and 6 times a week on the basis of the treatment in the control group.Treatment in both groups lasted for 2 weeks.Therapeutic efficacy indicators including visual analog scale (VAS),Oswestry disability index (ODI) and Barthel index (BI) were evaluated before and after treatment and at follow-up visit (1 month after treatment).Results:The total effective rate was 94.4％ and 88.9％ in the treatment group after treatment and at the follow-up visit,respectively,higher than 77.8％ and 69.4％ in the control group,and the between-group differences were statistically significant (both P＜0.05).After treatment and at the follow-up visit,the VAS and ODI scores decreased,and BI scores increased in both groups,and the intra-group differences were statistically significant (all P＜0.05).After treatment and at the follow-up visit,between-group differences of VAS,ODI and BI scores were statistically significant (all P＜0.05).Conclusion:On the basis of conventional medication treatment,point-toward-point needling at points on the low back regions has a good therapeutic effect in relieving residual back pain after PKP,improving thoracolumbar function and QOL,better than conventional medication treatment alone.

BACKGROUND:So far there are many studies about the uses of nano-carbon tracers in the diagnosis and treatment of malignancies. However, little has been reported on the mechanism underlying protective effect of nano-carbon tracers on the parathyroid glands during thyroid cancer surgery. OBJECTIVE:To study the protective effect of nano-carbon tracers on the parathyroid in thyroid cancer surgery. METHODS:180 cases of thyroid cancer were randomly divided into nano-carbon and control groups (n=90 per group):patients in the nano-carbon group were injected with nano-carbon tracers into the thyroid before surgery, and those in the control group underwent routine thyroid cancer surgery. Then comparisons of the operating time, incision length, blood loss, postoperative hospital stay, number of lymph node dissection, lymph node metastasis as wel as hypoparathyroidism rate were performed between two groups. Besides, levels of serum calcium and parathyroid hormone in the two groups were detected at 3 days after surgery. RESULTS AND CONCLUSION:There were no significant differences in the operating time, incision length, blood loss, postoperative hospital stay and lymph node metastasis between the two groups (P>0.05). The number of dissected lymph nodes of nano-carbon group was significantly higher than that of control group (P<0.05);the mis-resection rate of parathyroid and hypoparathyroidism of nano-carbon group were significantly lower than those of control group (P<0.05). Furthermore, the incidences of hypocalcemia and low parathyroid hormone of nano-carbon group were significantly lower than those of control group (P<0.05). These results suggest that the nano-carbon tracer plays a protective role on the parathyroid glands in thyroid cancer surgery, which can reduce the mis-resection rate of parathyroid, as wel as the incidences of hypoparathyroidism, hypocalcemia and low-level parathyroid hormone.

BACKGROUND: Preplant diagnosis and rigorous implant strategy based on multislice spiral computed tomography (MSCT) imaging can improve success rate of mini-implants as anchorage. Effective application of imaging information in implant anchorage requires reliable tools and methods.OBJECTIVE: To investigate the accuracy of the radiographic and tunnel-type surgical templates assisting implant anchorage surgery and evaluate the clinical significance.METHODS: The transparent radiographic templates were made with occlusal rest to assist MSCT to scan two pigs' skulls locatively. After designed the implant anchorage angles in MSCT images accurately, we made the tunnel-type surgical template by angle data. A total of 32 miniscrews were implanted by surgical template, and the two pigs skulls were rescanned by MSCT. After dissected the pig alveolar process, the MSCT preoperative planning angles, the MSCT postoperative measurement angles and the measurement angles of anatomic bone samples were analyzed statistically. RESULT AND CONCLUSION: The 32 miniscrews were implanted successfully. They did not damage dental roots or surrounding important structures. Compared MSCT preoperative planning angles with MSCT postoperative measurement angles and anatomic bone samples measurement angles, there were no significant differences on axial sections or cross-sections and the r concordance correlations were very good. Results show that the radiographic and the tunnel-type surgical templates are accurate and reliable for operation and will help to improve the success rate of implant anchorage.

Stem cells are a lineage with capacities of self-renewal and multipotential differentiation. They are exactly regulated by microenvironment where they live. With the understanding of stem cells biology, researchers noticed that stem cells have many similar biology characters with tumor cells, and thought that tumors were likely derived from stem cells, and gave a concept that there were tumor stem cells in tumor tissues.

Objective To analyze the constitutes of essential oil form Nervilia fordii. Methods GC-MS was used to analyze the essential oil. The relative content of each component was determined by area normalization. Results Fifty-five kinds of constitutes were identified,accounting 97.1 %of total contents. The content of 2-Pentadecanone,6,10,14-trimethyl is the highest,being 13.55 %,which had also been found in the same family. Conclusion 2-Pentadecanone,6,10,14-trimethyl can be used for the identification of the same family.

The clinical manifestation included snoring and mouth breathing for 2 years, repeated coughing and shortness of breath in action for more than 1 year. Physical examination of oral cavity showed tonsils were in grade III. The endoscopy showed 2/3 of postnaris were blocked by the adenoids. The preoperative ultrasonic cardiogram revealed the right atrial and right ventricular dilatation, pulmonary artery widened. The preoperative polysomnography (PSG) showed apnea-hypopnea index (AHI) was 28.5 events an hour, and the lowest oxygen saturation (LSaO2) was 39%. The patient was diagnosed as severe obstructive sleep apnea hypopnea syndrome with pulmonary hypertension. The postoperative PSG showed the AHI was 11.7 events an hour, and the LSaO2 was 86%. The ultrasonic cardiogram at 5 months after surgery didn't show any abnormalities.

AIM: To study the effects of fructose-1,6-diphosphate (FDP) on adriamycin (ADR)-induced calcium and sarcoplasmic reticulum Ca 2+-ATPase activity in cardiomyocytes of rats. METHODS: Rats were treated with ADR by intraperitoneal injection (2 5 mg?kg -1 body weight) once every two days for 11 days, and then ADR-treated rats were intervened by FDP at different dosages (ip) once every other day for 41 days. Enzyme linked immune absorption assay (ELISA) was employed to detect froponin I (CTnI). CK-MB was examined by monoclonal antibody. Intracellular free calcium concentration was measured on fluorescent spectrophotometry and SRCa 2+-ATPase activity was examined by inorganic phosphate. RESULTS: FDP (300, 600, 1 200 mg?kg -1) significantly reduced the levels of CTnI and CK-MB in serum. Decreased calcium and increased SRCa 2+-ATPase activity in cardiomyocytes were also observed when ADR-treated rats were intervened by FDP (P
