Objective To observe the effects of two rehabilitation programs to staff in office with cervical spondylosis,and to explore the appropriate rehabilitation program for this group of people.Methods There were 37 office personnel with cervical spondylosis were selected by the inclusion criteria.They were randomly divided into treatment group A(once a week,n=17) and treatment group B (once a week,n=20) according to the random number table method.The treatment group A took middle frequency electrotherapy and infrared therapy,while the treatment group B took tuina manipulation.The changes of visual analogue scale (VAS) and cervical range of movement (ROM) were observed after 10 weeks of treatment.Results Compared with before treatment,the VAS scores of the two treatment groups decreased with statistically significant difference after 10 weeks of treatment(tA=12.91,tB=13.88,all P<0.05).There was no significant difference in VAS score between the two treatment groups after treatment(t=0.22,P>0.05).Compared with before treatment,the cervical ROM of the two groups increased significantly after treatment(tA anteflexion=-4.59,tA posterior extension=-5.13,tA left flexion=-4.24,tA right flexion=-3.25,tA left circumflexion=-7.13,tA right circumflexion=-7.47,tB anteflexion=-5.85,tB posterior extension=-7.28,tB left flexion=-8.64,tB right flexion=-8.38,tB left circumflexion=-11.72,tB right circumflexion=-11.95,all P<0.05).There were significant differences in the increase range of flexion,left flexion and left circumflexion between the two treatment groups after treatment(tflexion=-2.29,tleft flexion=-2.77,tleft circumflexion=-2.32,all P<0.05),but posterior extension,right flexion and right circumflexion had no statistically significant diffferences(tposterior extension=-1.97,tright flexion=-1.97,tright circumflexion=-1.97,all P>0.05).Conclusion The two kinds of rehabilitation programs can relieve the neck pain of the office personnel,but treatment group B is better than treatment group A in increasing cervical ROM.

Objective To investigate the mechanism of platelet inhibitor from Agkistrodon halys venom (AHV-PI) on platelet aggregation. Methods Protein kinase Akt phosphorylation levels in platelet were measured by Western blot. XS-1000I blood cell counter was used for platelet count. The plasma content of 5'-NT and platelet membrane GPIb were determined by Enzyme-Linked Immunosorbnent Assay (ELISA). The effect of AHV-PI on binding rate between the fluorescence labeled monoclonal antibody CD61 (FITC-CD61) and platelet membrae glycoprotein Ⅱb/Ⅲa (GPⅡb/Ⅲa) was observed by flow cytometry (FCM). Results AHV-PI can reduce the level of Akt-phosphorylation level and the number of platelet. AHV-PI can increase the content of 5'-NT in plasma, reduce the expression of platelet GPIb. Flow cytometry displayed AHV-PI can not affect the rate of combination between platelet GPⅡb/Ⅲa and FITC-CD61. Conclusion The mechanism of inhibition of platelet aggregation may be inhibit protein kinase Akt phosphorylation to block the signal transduction pathway of Akt. Limit cell grouth and reduce platelet number, also it may be related to its 5'-NT activity, it can degradate ADP to prevent the formation of platelet thrombus.

Objective To summarize the sonographic characteristics of parathyroid adenomas(PAs) and investigate the diagnostic values and best diagnostic thinking for an early detection. Methods Sixteen cases finally proved with PAs were retrospectively analyzed of their clinical complaints, the department for their initial consultation,indicative ultrasound findings for neck scanning, major manifestations of PAs on a series of three-mode ultrasound imagings,association of adenoma sizes to serum parathyroid hormone(PTH) levels. Results On multimode ultrasound images, the PAs were multidisciplinary morphologic, homogenously hypoeehoic,absent of calculus and necrosis,highly vascularized with color signals,and similar to thyroid in contrast agents perfusion. Serum PTH levels were elevated in accordance with increase of adenomas' size. Among the 16 cases 12 were defined as with parathyroid incidentalomas, to which liver or/ and kidney stones were contributed as indicatives. Conclusions High frequency ultrasound with multiple imaging modes are most suitable for scanning and detection of neck PAs. For those with stones in liver and urinary tracts, unknown bone fracture etc, ultrasound scanning of the neck parathyroids used to reveal latent PAs.

Objective To investigate the amlodipine or hydrochlorothiazide and valsartan combination thera-py in elderly hypertensive patients with blood pressure variability ( BPV ) and nitric oxide ( NO ) , endothelin role. Methods 552 elderly patients with hypertension were divided into the observation group and control group,276 cases in each group,the observation group was given amlodipine valsartan for treatment,while the control group was received hydrochlorothiazide combined with valsartan for treatment,the two group were treated for three months,the content of BPV,NO and plasma endothelin were analyzed.Results After treatment,the 24hSBPV,day SBPV,24hDBPV,day DBPV of the observation group significantly decreased compared with pre-treatment, the difference was statistically significant(t=20.09,15.97,9.31,9.41,all P<0.05),patients in the control group only 24hSBPV and day SBPV [(9.12 ±2.57)%,(8.43 ±1.97)%]were significantly lower than before treatment(t=12.31,9.53,all P<0.05);The day SBPV,24hDBPV,day DBPV[(7.21 ±1.34)%,(12.31 ±2.54)%,(10.59 ±2.73)%]of the ob-servation group after treatment were significantly lower than those of the control group(t=10.52,12.34,8.35,all P<0.05);The NO[ (66.12 ±23.57)%,(68.29 ±21.52)%]and endothelin levels[(34.43 ±7.97)%,(34.21 ± 7.34)%]of the two groups after treatment were significantly lower than those of before treatment(tobservation grou P=31.39,11.79,tcontrol grouP=28.31,9.35,all P<0.05).Conclusion The amlodipine or valsartan hydrochlo-rothiazide used clinically can effectively control blood pressure, significantly increase NO levels, decrease plasma endothelin levels,which is worth to be used in the clinical.

Background and purpose: Little about the function of p53 isoforms in gastric cancer was reported. This study was designed to explore the role ofΔ133p53 in the effect of recombinant mutant human tumor necrosis factor (rmhTNF) on gastric cancer cells, and provide a new basis for the diagnostics and therapeutics of gastric carcinoma. Methods: MKN45 (withΔ133p53 expression) or SGC7901 (withoutΔ133p53 expression) cells were treated with rmhTNF of different concentrations only or combined with 5-FU (a traditional gastric cancer cellular killer), and the growth inhibition rate and apoptosis was detected by CCK-8 and lfow cytometry. mRNA expressions ofΔ133p53, Gadd45αand CyclinB1 were measured by nested reverse transcription-polymerase chain reaction (nRT-PCR) or real-time polymerase chain reaction(RT-PCR). Results:On MKN-45 cells with positiveΔ133p53 expression, the inhibitory effect of rmhTNF was signiifcant, the inhibition rates of 50 and 500 IU/mL rmhTNF were 24.82%, 72.33%after culturing for 24 h (t=-9.558, P<0.01);also, the inhibitory effect of 5-FU was improved by rmhTNF remarkably in time-and dose-dependence, the inhibition rates of 5-FU (25 μg/mL), rmhTNF (50 IU/mL) combined with 5-FU (25 μg/mL), rmhTNF (500 IU/mL) combined with 5-FU (25 μg/mL) were 18.20%, 48.66%, 59.83%, separately, after culturing for 24 h (F=82.742, P<0.01);the inhibition rates of rmhTNF (50 IU/mL) combined with 5-FU (25 μg/mL) were 48.66%, 68.20%, 85.23%, separately, after culturing for 24 h, 48 h and 72 h (F=128.583, P<0.01). However, on SGC-7901 cells with negativeΔ133p53 expression, no growth inhibition was showed by rmhTNF only, the inhibition rates of 50 and 500 IU/mL were 2.74%, 3.25%after culturing for 24 h (t=-0.121, P>0.05). In apoptosis test, the apopto-sis-enhancing effect of rmhTNF was signiifcant on MKN45 cells, and the apoptosis-enhancing effect of 5-FU was fur-ther promoted signiifcantly by rmhTNF, the apoptosis of rmhTNF (50 IU/mL), rmhTNF (50 IU/mL) combined with 5-FU (25 μg/mL), rmhTNF (500 IU/mL) combined with 5-FU (25 μg/mL) were 18.20%, 48.66%, 59.83%, separately, after culturing for 24 h (F=123.931, P<0.05). In mRNA measurement, down-regulation ofΔ133p53 and CyclinB1, up-regula-tion of Gadd45αwere signiifcant in MKN45 cells treated by rmhTNF alone or combined with 5-FU. In nRT-PCR anal-ysis, the mRNA levels ofΔ133p53 were relatively 0.886, 0.499, 0.330, 0.161 (F=240.927, P<0.01);In real-time PCR analysis, the mRNA levels of Gadd45αwere 1.227, 1.694, 3.394, and the mRNA levels of CyclinB1 were 1.221, 0.722, 0.316, relatively. The expression ofΔ133p53 was positively related to CyclinB1 (r=0.977, P<0.01), but negatively re-lated to Gadd45α(r=-0.950, P<0.01). Conclusion:InΔ133p53 positively expressed MKN45 cells, rmhTNF showed as an effective tumor inhibitor and an enhancer of 5-FU as well, and this effect might be helped by two p53 down-stream molecules CyclinB1 and Gadd45α. The results suggest thatΔ133p53 might be a key target for the biological effect of rmhTNF against gastric cancer.

To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.
