Objective: To evaluate the clinical effect of acupuncture in managing thalamic pain syndrome. Methods: Eighty patients with thalamic pain syndrome were randomly allocated into two groups, with 40 cases in the treatment group receiving combined scalp and body acupuncture treatment and 40 cases in the control group receiving single body acupuncture treatment. The intervention was given for 28 d in total, and the effects were evaluated after 14-day and 28-day treatments. Results: The inner-group comparison of McGill Pain Questionnaire (MPQ) showed significant differences after the treatment d 14 in both of the two groups (P<0.05), and after the treatment d 28, the differences were even more significant (P<0.01). After 28-day treatment, compared with pre-treatment, the Transcranial Doppler (TCD) test detected significant changes in the two groups (P<0.05). The total effective rate was 72.5% in the treatment group versus 47.5% in the control group, and the difference was statistically significant (P<0.05). The 3-month follow-up study found the relapse rate was 0 in the treatment group and 15.8% in the control group, and the difference was significant (P<0.05). Conclusion: Acupuncture is effective in treating thalamic pain syndrome and combined scalp and body acupuncture can achieve even better results.

Objective: To observe and evaluate the clinical efficacy and safety of using pediatric Tuina (Chinese therapeutic massage), Tui-Pushing chest-back manipulation, in treating children with cough variant asthma (CVA).Methods: Seventy-two kids with CVA were divided into two groups using the random number table method, with 36 cases in each group. The control group received the conventional Tuina treatment, and the observation group received additional Tui-Pushing chest-back manipulation. The clinical efficacy and adverse reactions were observed and recorded for the two groups. Results: After three treatment courses, compared with the control group, the observation group showed advantages in the total effective rate, reducing the number and intensity of cough and improving the nature of cough (P<0.05). However, at the one-month follow-up, there were no significant differences between the two groups in these parameters (P>0.05). Regarding the adverse reaction rate, there was no significant between-group difference (P>0.05). Conclusion: It is effective and safe to use pediatric Tuina, Tui-Pushing chest-back manipulation, plus the conventional treatment protocol to treat CVA in children.

Conclusion The digital 3D anatomical modeling of the mandible with full teeth has realistic 3D imaging view and convenient teaching-learning function , and has tremendous apllication futures in the stomatology , maxillofacial and other medical departments .

AIM: To investigate the effects of angiotensinⅡ receptor type Ⅰ antagonist irbesartan and angiotensin-converting enzyme inhibitor perindopril on the myocardial expression of connexin 43 (CX43), desmin and cardiac troponin T (cTnT) in the pressure overload-induced rat cardiac hypertrophy. METHODS: 40 male adult Sprague-Dawley rats were divided into 5 groups (8 animals for each): sham operation group and other four groups with ventricular hypertrophy caused by banding aortic artery. Drugs were given one week after operation as follows: sham operation group, normal saline (2 mL?kg~-1?d~-1 ig) was given; Operative groups: animals with ventricular hypertrophy were treated with normal saline 2 mL?kg~-1?d~-1 ig; Treatment groups: animals with ventricular hypertrophy were treated with perindopril 2 mg?kg~-1?d~-1 ig, irbesartan 20 mg?kg~-1?d~-1 ig or irbesartan 20 mg?kg~-1?d~-1 ig plus perindopril 2 mg?kg~-1?d~-1 ig, respectively. Left ventricular mass index (LVMI), transverse diameter of myocardial cell (TDM), and myocardial expression of CX43, desmin and cTnT by immunohistochemistry were performed at the end of 8 weeks of drug intervention. RESULTS: LVMI, TDM were remarkably decreased after drug intervention, compared to animals of operative group (P

Objective To investigate the effects of dexmedetomidine on hemodynamics and tra-cheal intubation facility in general anesthetized patients.Methods Forty gynecological patients of se-lective operation under general anesthesia were randomly arranged into 2 groups:group D and group C.With high flow mask oxygen inhalation(5 L/min),dexmedetomidine was intravenously pumped in-to the patients in group D at 0.6μg/kg in 10 minutes while in group C saline were given instead.Both groups were then proceeded with rapid sequence induction (RSI)immediately.The values of MAP, HR,PaO2 and PaCO2 were recorded every minute from pumping start till 15 minutes,the bucking, intubation time and glottis exposure were evaluated as well.Results No significant differences were found in intubation time or glottis exposure between these two groups.After tracheal intubation group D showed higher MAP value than group C at 14,15 minutes,and a lower HR value (P <0.05).Even no significant differences were found in values of SpO2 and PaO2 ,the group D showed less bucking than the group C (P<0.05).Conclusion Dexmedetomidine administration at 0.6μg/kg in RSI can diminish the variation in hemodynamics and facilitate the tracheal intubation by less buc-king,but no affect the oxygen reserve.

Objective To investigate the feasibility of establishing aneurysm model at the carotid artery bifurcation in experimental dogs. Methods New aneurysm model at the common carotid artery (CCA) bifurcation was established in 18 experimental dogs, which were randomly and equally divided into study group (n =9) and control group (n=9). In the dogs of the study group, the bifurcation top was treated with elastase, while in the dogs of the control group the bifurcation top was treated with saline. Angiography was separately performed immediately after, and at 12 and 24 weeks after the operation to observe the changes of the aneurysm top. Pathological examination was separately carried out at 12 and 24 weeks after the operation. Results Angiography showed that nascent aneurysm formation (mean diameter of 3.2 ± 0.4 mm) was demonstrated at the arterial bifurcation top in 5 dogs of the study group; while no nascent aneurysm at the arterial bifurcation top was observed in the control group. During the follow-up period, no rupture of the nascent aneurysm occurred in the study group. Pathological examination revealed that discontinued internal elastic membrane, elastic fiber fracture, thinning muscle layer and reduction of smooth muscle cells were detected in the aneurysm at bifurcation top in the study group; when compared with those in the control group, the difference was statistically significant (P< 0.001). Conclusion The elastase-induced digestive degeneration of artery wall can cause new aneurysm formation in the newly-established aneurysm located at carotid artery bifurcation in experimental dogs.

The facial, retromandibular and external jugular veins of the neck were studied in a total of 230 Chinese cadavers.1. The external jugular vein can be divided into six types and fourteen subtypes. Type Ⅰ(40.22％) and type Ⅲ (29.13％) occurred more frequently in this series.2. The facial vein drains into the external jugular vein in 41.09％. It drains directly or indirectly into the internal jugular vein in 43.91％.3. The anterior branch of the retromandibular vein usually drains into the internal jugular vein and it runs through the space deep to the posterior, belly of the digastric and the stylohyoid muscles in 83.70％.4. The presence of the so called common facial vein occurred only in 29.13％.5. The external jugular vein often drains into the subclavian vein. It appears in 46.57％ in our observation.6. The external jugular vein crosses the inferior belly of the omohyoid muscle, when it runs downwards in the lower part of the external cervical triangle. It usually lies superficial to the omohyoid in 66.16％, deep to it in 26.35％.
