Objective To study the application value of steelwire perforation and cerclage in treatment of comminuted clavicular fracture. Methods 32 patients with comminuted clavicular fracture were treated with steelwire perforation and cerclage. Two holes were made at the lateral margin at the ends of fractured clavicle, then a steel wire of 0.6mm in diameter passed through them and fixed the fracture. The bone fragments were fixed either with perforation or with cerclage according to their size and shape. Results The mean follow up time was 59 months. All the 32 cases of fracture healed within expected time. The function of the shoulder joints recovered well, with the excellent and good rate being 90.6% . Conclusion The steelwire perforation and cerclage bears advantages of being less traumatic, providing stable fixation, promoting fracture healing and making the secondary operation easy.

Objective To observe the clinical efficacy of acupuncture at the six mind-calming points plus the four gate points in treating migraine.Method Totally 128 eligible migraine patients were randomized into a treatment group and a control group, 64 cases in each group. The treatment group was intervened by acupuncture at the six mind-calming points plus the four gate points, while the control group was by ordinary acupuncture. The Numerical Rating Scale (NRS), headache attack frequency, headache duration, headache intensity, complicated symptoms, Self-rating Depression Scale (SDS), and Self-rating Anxiety Scale (SAS) were observed before and after treatment and in the follow-up study.Result The NRS scores and the headache symptoms and functions scores were significantly changed respectively after 2-week and 4-week treatment in both groups (P<0.01,P<0.05). The NRS score, headache duration, and headache intensity in the treatment group were significantly different from that in the control group after 4-week treatment and in the follow-up study (P<0.05,P<0.01). The SDS and SAS scores were significantly changed after 2-week and 4-week treatments as well as in the follow-up study in the treatment group (P<0.01). The SDS and SAS scores were significantly changed after 4-week treatment in the control group (P<0.01). There were significant differences in comparing the SDS and SAS scores between the two groups after 2-week and 4-week treatment as well as in the follow-up study (P<0.05,P<0.01). In the treatment group, the SDS and SAS scores in the follow-up study were significantly different from that after 2-week treatment (P<0.01).Conclusion Acupuncture at the six mind-calming points plus the four gate points is an effective method in treating migraine, and it can reduce headache intensity, and improve the anxiety and depression state.

Objective:To detect the expression and clinical significance of β-tubulin Ⅲ in cancer tissue of the patients with colon adenocarcinoma,and to explore its clinical significance.Methods:A total of 111 colon adenocarcinoma tissue samples were obtained.According to the location of β-tubulin Ⅲ positive cells, all patients were divided into front group (n=72) and non-front group (n=39).The positive expression rate of β-tubulin Ⅲ in the patients with colon adenocarcinoma was detected with immunohistochemistry.The correlations among the expression of β-tubulin Ⅲ and gender,age,tumor differentiation, clinical stage, lymph node metastasis, recurrence and death were analyzed.Results: The expression levels of β-tubulin Ⅲ had no significant differences between the patients with different gerder,age,lymph node metastasis,clinical stages,death and recurrence.The positive expression rates of β-tubulin in cancer tissue of the patients had significant difference between front and non-front groups (χ2=8.76, P=0.01).Lowly-to-moderately differentiated tissue was more common in front group, and highly-differentiated tissue was more common in non-front group(χ2=6.88, P=0.03).There were significant differences in the expression levels of β-tubulin Ⅲ between cancer tissues with different differentiation degrees (χ2=5.74, P=0.04).In non-front group, lymph node metastasis was closely correlated with the expression of β-tubulin Ⅲ (χ2=6.02,P=0.05).The results of immunohistochemical staining showed that the β-tubulin Ⅲ positive-expressing cells were colored brown-yellow.The number of cells with positive β-tubulin Ⅲ expression was significantly increased in highly differentiated tissue compared with low-differentiated tissue.Conclusion:The expression of β-tubulin Ⅲ is closely related to tumor differentiation in colon adenocarcinoma tissue.The highly differentiated colon adenocarcinoma tissue is more common in non-front group in which the expression of β-tubulin Ⅲ is related to lymph node metastasis.

Objective To observe the effect of nerve growth factor(NGF)and electro-acupuncture(EA) on learning and memory in rats with cerebral ischemia.Methods An experimental model of cerebral ischemiareperfusion was established in 40 rats,who were then randomly divided into a model group,a sham operated group,a NGF group,an acupuncture group and a NGF plus acupuncture group.Three weeks were allowed for the recovery of the blood-brain barrier lesion caused by ischemia-reperfusion before intravenous injection of NGF(10μg/kg,once daily for 15 days)via the vena caudalis.In the two acupuncture groups,this was administered in combination with EA at the Baihui(DU20)and Yamen(DU15)acupoints(frequency 100 Hz,2 mA,20 min/time,once daily for 15 days).Morris' water maze test was used to assess any changes in spatial learning and memory abilities.Results The ischemic rats showed significant learning and memory disorders compared with the sham-operated group.In the NGF group,the rats' learning and memory abilities did not impmve significantly compared with the model group and the EA group.Significantly better learning was observed in the NGF+EA group compared with the model group,the EA group and the NGF group.Conclusion NGF combined with EA can improve the learning and memory abilities of rats with learning and memory dysfunction caused by cerebral ischemia-repedusion.

Objective To investigate the value of high frequency 2-Dimensional and color Doppler flow imaging combined with mammography on the diagnosis of breast cancer. Methods 90 patients with breast cancer and benign breast lesions in 22 cases, respectively, separate by color Doppler ultrasound and mammography and their combination were compared. Results The blood flow signals were Ⅱ～Ⅲ grade(76.32% ) in breast cancer and benign breast lesions less blood flow to 0 ～Ⅰ grade ( 87.10% ); The detection rate of blood flow 89.48% in breast cancer were significantly higher than 38.71% in benign breast lesions ( x2 = 4.57, P ＜ 0. 05 ); 68 cases (75.5 % ) were diagnosed by mammography 38 cases(55.8% ) in diameter≤2. 0em were significantly higher than 30 cases(44.4% ) in ≤ 1.0 cm( x2 = 3.97, P ＜ 0. 05 ); The corresponding rate of Joint Inspection 85.7 % (96/112) was higher than the r 72.3% (81/112) in color Doppler ultrasound and 75.8% (85/112) in mammography ( x2 = 3.87, x2 = 3.85, all P ＜0. 05 ). Conclusion Color ultrasonography combined with mammography could raise diagnostic rate of breast cancer.Their combination is the best one of breast imaging examinations.

Aim To investigate the influence and molecular mechanism of C-phycocyanin(CPC) from Spirulina platensis on apoptosis of HeLa cells in vitro.Methods Firstly,the effect of purified CPC on proliferation of HeLa cells in vitro was determined by MTT assay,and then electron microscope was exploited to observe the characteristic apoptotic features of cells treated with CPC.Subsequently,genomic DNA changes of HeLa cells were observed by agarose electrophoresis.Flow cytometric analysis revealed the influence of different concentrations of CPC on cell cycle of HeLa cells.The expressions of apoptosis related genes of CPC treated HeLa cells were determined by immunohistochemistry analysis.In addition,the activities of caspases and the release of cytochrome c from mitochondria into the cytosol were detected.Results Compared with control cells untreated with CPC,a significant decreased in the numbers of HeLa cells in survival treated with CPC and concentration dose effects existed.CPC could induce characteristic apoptotic features including cell shrinkage,membrane blebbing,microvilli loss,chromatin margination and condensation into dense granules or blocks.DNA of HeLa cells treated with CPC showed fragmentation pattern(DNA ladder of oligomers of 180~200 bp) typical for apoptotic cells.HeLa cells treated with different concentrations of CPC demonstrated an increasing percentage of cells in sub-G0/G1 phase.In addition,CPC could promote the expression of pro-apoptotic gene(Fas and ICAM-1);meanwhile,held back the anti-apoptotic gene(Bcl-2) expression,and then facilitated the transduction of tumoral apoptosis signals that resulted in the apoptosis of HeLa cells in vitro.In CPC treated HeLa cells,CPC treatment of HeLa cells also resulted in activation of caspases and release of cytochrome C from mitochondria into the cytosol.Conclusion C-phycocyanin from Spirulina platensis can induce the apoptosis of HeLa cells in vitro.By virtue of the promotion of the apoptosis signals transduction in HeLa,CPC realizes its antitumor activities.

Objective To observe blood glucose values and serum insulin levels at different times after acupoint injection of insulin with PVP as a sustained release agent and analyze the correlation between them in SD Rats.Methods One hundred and forty-four male SD rats were randomized into groups A (acupoint injection of insulin alone), B (acupoint injection of sustained-release insulin) and C (control). At one hour after every group received an oral gavage of 40% glucose solution (2.2 g/kg), groups A and B were given point Zusanli injection and group C was not treated. In the three groups of rats, blood glucose values and serum insulin levels were measured at six time points: 0.5, 3, 6, 8, 10 and 24 hours after acupoint injection (in group C at the corresponding time points). In every group, the reaction of Point Zusanli region to the stimulation was observed by optical microscopy in at three time points: 3, 10 and 24 hours after acupoint injection.Results The glucose-lowering rate reached its peak at 3 hours after acupoint injection and then declined in groups A and B. The hypoglycemic effect tended to be stable at 6 hours after acupoint injection in group A and at 10 hours after acupoint injection in group B. The hypoglycemic effect was better in group B than in group A at 6 and 8 hours after acupoint injection (P<0.01). In group A, serum insulin reached its peak at 3 hours and tended to be stable at 6 hours after acupoint injection (P<0.05). Serum insulin levels were significantly lower in group B than in group A at four time pints: 0.5, 3, 6 and 8 hours after acupoint injection (P<0.05). An analysis of the correlation between rat serum insulin levels and the glucose-lowering rate showed a significant positive correlation in group A (P<0.01) and a low positive correlation in group B (P<0.05). In groups A and B of rats, clear stripes and complete structure of muscle fibers were seen with no obvious degeneration, necrosis and inflammatory reaction around point Zusanli at three time points: 3, 8 and 24 hours after acupoint injection; there were no obvious pathological changes compared with group C.Conclusions PVP as a sustained release agent can slow down the absorption rate of insulin in rat point Zusanli region. Meanwhile, it prolongs the continuous time of the hypoglycemic effect of insulin. There is a low correlation between serum insulin levels and the hypoglycemic effect, suggesting that acupoint injection with a sustained release agent can prolong the effect of acupoint injection of medicine.
