OBJECTIVETo analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

METHODSFrom October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation.

RESULTSAll operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases.

CONCLUSIONIt's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.

OBJECTIVETo study the solubilization effect of 2-hydroxypropyl-beta-cyclodextrin(HPCD) on paeonolum at various pH value.

METHODPhase-solubility method was adopted to study the solubilization effect at 25 degrees C and UV spectrohotometer was used to determine paeonolum content.

RESULTSThe apparent solubility of paeonolum was significantly enhanced by increased HPCD concentration. The apparent stability constant of paeonolum compounds was calculated up to 1 425 in which pH was 3 and HPCD concentration was 133.33 mmol x L(-1). The solubility of paeonolum came up to 10 mg x mL(-1).

CONCLUSIONHPCD is an ideal solubilizer for paeonolum.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

Objective To evaluate the possible interactions among different impact factors possibly affecting the treatment efficacy of 131I in Graves′ disease (GD). Methods Six hundred and thirty two GD patients that had been treated by 131I, with or without antithyroid drugs (ATD), were included in this study. The impact factors were pre-defined as age (x1), sex (x2), mass of thyroid (x3), course of disease (x4), initial symptom (x5), condition of disease (x6), ATD treatment duration (x7), effective half life time (x8), maximum 131I uptake rate (x9), total dose of 131I (x10), dose of 131I per gram of thyroid (x11), TRAb (x12), TSI (x13), TgAb (x14), and thyroid microsomal antibody(TMAb) level(x15). Interactions among different impact factors were studied by t-test, χ2 test and multi-variant logistic regression. Results Age, mass of thyroid, ATD treatment duration, maximum 131I uptake rate, dose of 131I per gram of thyroid tissue and TSI level were identified as independent impact factors affecting the 131I treatment efficacy on GD (χ2=6.908, t=-4.063, χ2=13.558, t=-2.553, t=4.528, χ2=9.716, all P<0.05) by uni-variant and multi-variate analyses. Loglinear and general linear model analyses showed that there existed multiple multiplicative and additive interactions among the factors of age, mass of thyroid, ATD treatment duration and maximum 131I uptake rate (likelihood χ2=8.176, P>0.05; F=2.928, 1.992, 2.629, 2.215, all P<0.05), which indicated that the treatment efficacy with co-existing multiple factors was not equal to simple summation of single factors. Conclusions The interactions among multiple factors can cause indi-rect effect on 131I treatment, which might guide the prescription of 131I dosage for GD treatment.

OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.

The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and β-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the β-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.

To explore the method of explants directly induced bud and establish the tissue culture system of mutiple shoot by means of direct organogenesis, core bud and daughter bulbs (the top of bud stem expanded to form daughter bulb) of T. edulis were used as explants and treated with thidiazuron (TDZ) and 1-naphthlcetic acid (NAA). The results showed that the optimal medium for bud inducted form core bud and daughter bulb were MS + TDZ 2.0 mg x L(-1) + NAA 4.0 mg x L(-1) and MS +TDZ 2.0 mg x L(-1) + NAA 2.0 mg x L(-1) respectively, both of them had a bud induction rate of 72.92%, 79.22%. The optimal medium for cluster buds multiplication was MS + TDZ 0.2 mg x L(-1) + NAA 0.2 mg x L(-1), and proliferation coefficient was 2.23. After proliferation, cluster buds rooting occurred on MS medium with IBA 1.0 mg x L(-1) and the rooting rate was 52.6%, three to five seedlings in each plant. Using core bud and daughter bulb of T. edulis, the optimum medium for adventitious bud directly inducted from daughter bulb, core bud and cluster bud multiplication were screened out and the tissue culture system of multiple shoot by means of direct organogenesis was established.

OBJECTIVETo observe the characteristics of uterine contraction and stages of labor during delivery under continuous epidural block anesthesia.

METHODSTotaling 213 parturients in spontaneous labor under epidural block anesthesia with dilated cervical orifice of 3 cm were monitored for the contraction cycle, duration, intensity and curve types of uterine contraction, and recordings were made for 30 min before and 30, 60 and 120 min after the anesthesia took effect, respectively. The duration of the active phase in the first, second and third stages of labor was compared between 421 cases with anesthesia and 237 without anesthesia.

RESULTSSignificant difference was noted in the objective indexes of uterine contraction recorded after anesthesia had taken effect (P<0.05) in comparison with those before anesthesia, suggesting significantly attenuated uterine contraction after anesthesia, whereas these indexes underwent no significant further variation as compared between different time points after anesthesia (P>0.05). The average active phase in the first stage was significantly shorter in anesthesia group than that in the control group (P<0.05), but the average duration of the second and third stages of labor differed little between the two groups with appropriate use of oxytocin under strict monitoring (P>0.05). The rates of obstetric forceps utilization and use of oxytocin were higher in anesthesia group than in the control group (P<0.05).

CONCLUSIONEpidural block anesthesia produces certain influences on uterine contraction and stages of labor during delivery, for which appropriate treatment measures may prove beneficial.
