This paper introduces a kind of clinical thermometer, which can be wor n on the breast, leg and other parts of the body. It can acquire the temperature data through a large-capacity data memory and the data can be processed by the computer.

Objective The properties of anthocyanins in Suaeda heteroptera Kitag.were investigated.Methods Properties of the extract were determined via spectral absorption,physco-chemical analyses.Results Spectrogram results showed that the red pigment was classified to anthocyanins.The color properties of the pigment were similar to plant anthocyanins and pH changes could affect the tone of the color.The pigment was soluble in water,alcohol;slightly soluble in acetone;and insoluble in petroleum ether.Under natural light,degradation of the pigment could be accelerated.High temperature was disadvantage to the pigment stability.Redox stability was very low.Fe~(2+),Mg~(2+),Cu~(2+) and Mn~(2+) did not significant affect the tone of the color.Conclusion The pigment from Suaeda heteroptera Kitag.is water-soluble anthocyanins,and may be important nature edible pigment resource.

Objective: To study the effect of zinc deficiency on the growth and concentrations of related hormones in serum of pregnant rats. Methods: Pregnant Wistar rats were assigned to zinc deficiency(ZD),pair-fed(PF),zinc supplement(ZS) and control(Cont) group and fed for 21 days with zinc deficient(0.7 mg/kg)diet(ZD rats)or a similar diet supplemented with 100 mg Zn/kg.The growth of pregnant rats was observed and the concentrations of triiodothyronine(T 3),thyroxine(T 4),thyrotropin(TSH) and growth hormone(GH) in serum of rats were determined with radioimmunoassay. Results: The ZD rats didn't gain weight.The birth weight of fetuses in ZD group was significantly lower than that of other groups (P

Objective To investigate the effect of posterior operation for thoracolumbar burst fractures combined with dislocation. Methods The study involved 22 patients with thoracolumbar burst fractures combined with dislocation admitted into our hospital from October 2005 to March 2008. There were 17 males and 5 females at age range of 18-56 years. The fractures were located at T12-L2. The fractured vertebrae lost its height by 1/4 to 3/4 of the normal height. The upper vertebral dislocation ex-tent was from 25% to 50%. All operations were accomplished within two weeks after injury. The patients were randomly divided into two groups, ie, Group Ⅰ (implanted with 4 pedicle screws in upper and lower vertebrae adjacent to the fractured vertebrae) and Group Ⅱ (implanted with 6 pedicle screws in 2 upper and 1 lower vertebrae adjacent to the fractured vertebrae). The operation time, volume of blood loss, ky-photic angle, neurological function and Low Back Outcome Score (LBOS) were compared between two groups. Results All patients were followed up for 12-36 months. The duration of operation in Group Ⅱ was longer than Group Ⅰ (P < 0.05), with no increase of intraoperative blood loss. Group ⅡI was su-perior to Group Ⅰ in aspects of correction rate, correction loss and implant failure rate (P < 0.05). There was no statistical difference in aspects of neurological function recovery and low back outcome score be-tween two groups. Conclusion Fixation with three vertebrae and six pedicle screws through posterior approach is an effective, feasible and safe procedure for treatment of thoracolumbar burst fractures com-bined with dislocation.

Objective　To evaluate the methods of surgical treatment for tumors of brain stem and their curative effects. Methods: 25 cases of tumors of brain stem were analysed retrospectively. Results: There were 18 cases of astrocytomas, 2 cases of cavernous angioma, 1 cases of hemangioblastoma, 1 cases of dermoid cyst, 1 cases of syringopontia, 1 cases of inflammatory granuloma accompanied with hecrosis and 1 cases of AVM of brain stem in 25 cases. Four patients died after operation. Conclusion: Extrinsic tumors of brain stem could be resected totally or subtotally, resulting in good outcome.

OBJECTIVE:To study the safety and efficacy of Neuroform self-expanding stent for symptomatic intracranial artery stenosis.METHODS:A total of 37 patients with symptomatic intracranial artery stenosis received treatment at the Department of Neurosurgery,Affiliated Hospital of Behua University and Xuanwu Hospital were selected,who were ineffective to anticoagulation and antiplatelet treatment,including 24 males and 13 females,aged from 49 to 72 years,mean aged 64 years.All patients were received Neuroform self-expanding stent following angiography.RESULTS:All patients underwent PTAS with mean preoperative stenosis were reduced from 64% to 24% after percutaneous transluminal angioplasty (PTAS).The technically successful rate was 100%.All the patients were received a 6-22 month follow-up (average 13 months).The average artery stents was retrieved by 50%-90% after stent deployment.There was no arterial dissection,acute occlusion of the target artery or symptomatic distal emboli.Within the follow-up period,1 patient endured asymptomatical artery full occlusion.Two stents were implanted simultaneously in 3 patients,1 of them suffered bilateral vertebral artery stenosis,and 2 had right vertebral arterial and basilar artery stenosis.One patient suffered acute in-stent thrombosis and recovered after thrombolytic therapy.No pathogenetic condition was aggravated in the follow-up.CONCLUSION:The application of Neuroform self-expanding stent can alleviate the ischemic symptoms of patients with vertebrobasilar stenosis and elevate the operative safety and effectiveness.However,further study is needed to evaluate the long-term therapeutic effect.

Objective To investigate the effects of simultaneous multi-level surgery for moderate to severe obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A retrospective analysis was made on surgical cases of one hundred and thirty seven patients with moderate to severe OSAHS diagnosed by polysomnography (PSG). They were divided into multi-level group (n = 95) and UPPP group (n = 42). The two groups were compared in terms of postoperative complications as well as the related indicators of PSG , calgary sleep apnea quality of life index (SAQLI), epworth sleepiness scale (ESS), snore scales (SS) before operation and after operation. Results Just one patient in the multi-level group had difficulties in respiration and was rescued by timely tracheotomy. The AHI, LSaO2, TS90%, the total score and the scores on the four dimensions of SAQLI, ESS score, SS score in the multi-level group were significantly improved as compared both to the results after operation (P < 0.01) and to the UPPP group (P < 0.05). But only the AHI, LSaO2 and TS90% in the UPPP group were improved (P < 0.05). Conclusions The multi-level surgery is a safe and feasible therapy or moderate to severe OSAHS. The evaluation in subjective and objective ways can be more accurate in comprehensive reflecting the surgical efficacy and effects of OSAHS on patients′ of life quality.

To compare the distribution characteristics of common syndrome types and syndrome elements of menopause syndrome in perimenopausal and postmenopausal women on the basis of standardized syndrome differentiation extracted by experts' experiences.

Objective: To investigate the clinical efficacy of reduced port laparoscopic radical resection on colorectal cancer. Methods: Clinical data of 46 patients with colorectal cancer undergoing reduced port laparoscopic radical resection were retrospectively analyzed. Results: All of 46 patients underwent laparoscopic surgery, with an average operation time of 206 minutes, an average intraoperative bleeding of 56 ml, an average number of lymph nodes removement of 12/case (ranged from 6 to 21). One case had incision infection, 2 cases had anastomotic leakage, and they all recovered and discharged after treatment. Conclusions Reduced port laparoscopic radical resection of colorectal cancer is safe and feasible, reduces labor costs, and has a good clinical efficacy, which is worthy of clinical promotion.
