Thyroid cancer is one of common malignant tumor in neck, which can occur in any age. Females are more likely to have this disease than males. Most patients get a nodule on their thyroid, which typically does not cause any symptoms. Surgical resection is an effective method to cure thyroid cancer. In recent years, more and more evidence support that traditional Chinese medicine plays an important role in the recovery of postoperative thyroid carcinoma.

Objective To investigate the myocardial remodeling inhibition effect of bisoprolol combined with trimetazidine in the treatment of hypertensive myocardial hypertrophy.Methods 86 cases with hypertension and cardiac hypertrophy in Lingwu People’s Hospital of Ningxia from June 2015 to June 2016 were selected and randomly divided into two groups,43 cases in the control group received routine clinical treatment,43 cases in the experiment group received more with bisoprolol combined with trimetazidine treatment.Blood pressure,ultrasonic cardiogram,levels of serum TNF-α, MMP3 and CRP were compared before and after the treatment.Results Compared with before treatment,levels of blood pressure,IVST,LVPWT,LVMI, MMP3,TNF-αand serum CRP significantly decreased after treatment,and compared with the control group,levels of blood pressure,IVST,LVPWT, LVMI,MMP3,TNF-αand serum CRP in the experiment group were lower,the differences were statistically significant (P<0.05),and the effective rate in the experiment group was higher than the control group ( P<0.05 ) .Conclusion Bisoprolol combined with trimetazidine can effectively inhibit the remodeling of hypertension in patients with myocardial hypertrophy,has good clinical efficacy.

Objective To observe the postoperative analgesia effect of ultrasound-guided trans-versus abdominis plane block (TAP)in patients received lower abdominal surgery.Methods Ninety patients undergoing lower abdominal surgery were randomly divided into group A (received TAP), group B (received patient controlled intravenous analgesia with sulfentanil),and group C (received patient controlled epidural analgesia with sulfentanil and ropivacaine)for postoperative analgeda.All patients received combined spinal and epidural anesthesia.VAS score at postoperative 2,4,8,16 and 24 h,as well as the side effects related to postoperative analgesia,were observed and recorded for each patient.Results Comparing with group A,VAS scores of group B at postoperative 2,4,8,16 and 24 h were obviously higher (P< 0.05);Comparing with group A,VAS score of group C at post-operative 24 h was obviously lower (P< 0.05).Comparing with group A,nausea and vomiting,pru-ritus,and somnolence were more obvious in group B (P < 0.05);nausea and vomiting,sensory and motor abnormality of lower limbs and urinary retention occurred more frequently in group C (P <0.05).Conclusion Ultrasound-guided TAP can effectively relieve postoperative pain 24 hours,and has no obvious side effect in patients received lower abdominal surgery.

The present study was performed to determine whether or not that cardiacrenin-angiotensin system (RAS) plays an important role in volume-overload myocardialhypertrophy. In order to control the increase of circulating RAS, aortacava fistula withnephrectomy (ACF+NT) rats were used in the experiment. The ventricular angiotensin Ⅰ,Ⅱ (Ang Ⅰ,Ⅱ) contents and angiotensin-converting enzyme (ACE) activities were measuredby means of radioimmunoassay and biochemical method. It was shown that in ACF+NTrats, the Ang Ⅱ contents and ACE activities in both left and right ventricles increasedsignificantly despite the plasma Ang Ⅰ, Ⅱ and renin activity remained at a lower level.These results indicate that: (1) Cardiac RAS as a relatively independent system, plays aregulatory role in the development of volume-overload cardiac hypertrophy; (2) The in-crease of Ang Ⅱ content was partly caused by the enhancement of ACE activities; (3) Atleast at the early stage of volume-overload cardiac hypertrophy, the circulating RAS maynot be a necessary promoter.

Objective To study the dynamic changes of DNA content of the fibroblasts in narrow pedicle subdermal vascular network flap (SVNP) during their surviving. Methods Eighteen pieces of surviving skin in pig back with size of 16 cm?8 cm and pedicle wideness of 4 cm were stained with acridine orange, and their DNA contents were measured with the adherent cell analysis and sorting cytometer 570. The tissue samples were taken at 3, 4 ,5 ,and 7 days after operation from different parts of the flap.Results The DNA content of fibroblast in the proximal part of the flap was slightly changed, those in the middle portion increased from 3rd to 5th day and became normal at 7th day, and in the distal portion progressively increased after operation. The results suggested that the transitional part of the flap and skin graft in the middle portion was most active in function and metabolism, and well survived, but the distal portion of the graft was poor in surviving and had a long repairing period. These indicated that local tissue hypoxia stimulated proliferation of fibroblasts and synthesis of the DNA in a short time, but as time wert by, the proliferative speed and DNA synthesis in the individual cell were heterogeneous, probably because of the degeneration or necrosis of some epidermal cells in the graft. Conclusion The wideness and length of the pedicle as well as its vascular anastomoses should be readjusted to promote the blood circulation of the distal skin graft tissues.

Hyperuricemia mice model was established with uricase inhibitor (potassium oxonate) and uric acids in serum were observed. Polydatin (5, 10, 20 mg · kg(-1)) and benzbromarone (16.7 mg · kg(-1)) were given ig for 7 d in mice. Kidney tissues were used to detect gene contents ofurate anion transporter 1 (URAT1), organic anion transporter 1 (OAT1) and organic anion transporter 3 (OAT3) by real-time-PCR. The results showed that polydatin and benzbromarone can significantly reduce uric acid in blood of hyperuricemia mice (P < 0.05), compared with the model group. URAT1, OAT1 and OAT3 contents of the kidney in hyperuricemia mice changed significantly (P < 0.05), compared with the blank group. Polydatin can significantly inhibit the changing trends in these genes induced by potassium oxonate in a dose-dependent manner, the difference was significant (P < 0.05), compared with the model group. Those indicated that polysatin could reduce the level of the serum uric acid through promoting uric acid excretion.

Objective　To explore the effect of photon on blood biologic components in blood photochemical treatment. Methods　After the blood sample was adjusted to an appropriate density, it was treated with 0.1 nmol/ml 8-MOP (8-methoxypsoralen), 0.1 nmol/ml TFO (triple helix-forming oligonuletide) and UVA (ultraviolet A radiation) at the intensity of 1 800 μW/cm2 for 3～20 min. The changes of biologic activities of major components in blood were measured with automatic blood gas analyzer, platelet aggregation analyzer, blood coagulation analyzer, micropipette aspiration system and assay of poly-lysine adsorption. Results　The oxygen content in blood was increased gradually. The resilience of erythrocyte was enhanced ，but its adhesiveness was decreased. The parameters related to blood coagulation had some changes but all remained within the normal ranges. Conclusion　Under the definite condition of blood virus being inactivated effectively, the nonspecific effect of photosensitive response may improve blood oxygen content, enhance the transfiguring ability of erythrocyte and decrease the blood viscosity, but having no obvious change on blood coagulation.
