Objective To investigate the clinical efficacy of auricular plaster therapy plus scalp acupuncture in treating post-stroke depression.Methods One hundred and twenty-five patients with post-stroke depression were randomly allocated to group A of 42 cases, group B of 42 cases and group C of 41 cases. Group A received scalp acupuncture alone; group B, auricular plaster therapy alone; group C, auricular plaster therapy plus scalp acupuncture. The Hamilton Depression Scale (HAMD) score was recorded in the three groups before and after treatment. The clinical therapeutic effects were compared between the three groups. Results There was a statistically significant pre-/post-treatment difference in the HAMD score in the three groups after two months of treatment (P<0.01). There was a statistically significant difference in the HAMD score between group C and group A or B after one and two months of treatment (P<0.05). The total effective rate and marked efficacy rate were respectively 95.0% and 33.3% in group A, versus 88.1% and 35.7% in group B, and 92.7% and 56.1% in group C, and the marked efficacy rate in group C were significantly different from that in group A and group B (P<0.05). There is not a statistically significant difference in the total effective rate among the three groups (P>0.05).Conclusion Auricular plaster therapy plus scalp acupuncture is an effective way to treat post-stroke depression.

Objective:To investigate the physical morphology of the root canal taper in human maxillary and mandibular permanent first molars.Methods: Forty maxillary and 44 mandibular extracted human permanent first molars were investigated.The roots were dissected transversely from their apical foramen vertical to the long axis of the root,and 1-mm-thick serial sections were made.The root apex side of each section was observed with a stereomicroscope at 30? magnification.The maximum and minimum canal diameters were measured at 0,1,2,and 3 mm from the apical foramen.The physical canal taper in the apical section was calculated.Results: 47.5%-60.0% of the narrowest diameter of root canals were present at the foramen,and 25.0%~42.5% located at the level of 1 mm from apical foramen.Almost all physical configurations of root canals in 3 mm apical region showed a bottleneck-like taper.Canal dia-meters increased rapidly at 1-2 mm with the biggest taper,and the taper had a bigger variance(0.07-0.35).The ring of shrunken bottleneck was formed at the level of 1 mm from apical foramen.The taper of canal in maximal diameter was larger than the one in minimal diameter.Conclusion: The physical morphology of bottleneck-like taper in apical canal was helpful to locate the canal apical stop in root canal treatment.

Objective To investigate the efficacy of fascia iliaca compartment block combined with general anesthesia for total hip arthroplasty.Methods Fifty patients underwent total hip arthroplasty were divided into trial group or control group by random digits table method with 25 cases each.Preoperatively,both groups were given fascia iliaca compartment block with the trial group receiving 60 ml 0.25％ ropivacaine and the control group receiving 60 ml 0.9％ sodium chloride.Both groups received general anesthesia.The consumption of general anesthetics and intraoperative hemodynamic variation in the 2 groups were recorded.The recovery time,extubation time,observer's assessment of alertness/sedation score (modified OAA/S) at 15 and 30 min postoperative and visual analog score (VAS) at postoperative instantly were compared between the 2 groups.Results The consumptions of propofol and remifentanil during maintenance of anesthesia in trial group were significantly lower than those in control group,and there were statistical differences:(250 ± 40) mg vs.(420 ± 85) mg and (300 ± 50) μ g vs.(600 ± 150) μ g,P ＜ 0.01.The recovery time and extubation time in trial group were significantly shorter than those in control group,and there were statistical differences:(7.2 ± 4.5) min vs.(16.2 ± 7.1) min and (8.0 ± 2.8) min vs.(20.0 ± 8.3) min,P ＜ 0.01.The modified OAA/S at 15 and 30 min postoperative in trial group were significantly higher than those in control group,and there were statistical differences:(4.3 ± 0.3) scores vs.(3.0 ± 1.2) scores and (4.6 ± 0.2) scores vs.(3.9 ± 0.8) scores,P ＜ 0.01.The VAS at postopcrative instantly in trial group was significantly lower than that in control group,there was statistical difference:(1.6 ± 0.9) scores vs.(4.5 ± 0.8)scores,P ＜ 0.01.The degree of satisfaction in trial group was better than that in control group,and there was statistical difference (P ＜ 0.05).Conclusion Compared with general anesthesia alone for total hip arthroplasty,the fascia iliaca compartment combined with general anesthesia has better hemodynamic stability,marked reduction of consumption of general anesthetics,rapid recovery and good postoperative analgesia.

Objective To investigate the differences of symptoms,physical signs and examinations in childhood and adult patients with Marfan syndrome.Methods Twenty-four children diagnosed as Marfan syndrome were investigated and evaluated synthetically in symptoms,physical signs and examinations.The positive rate of each item was analyzed to find the differences between childhood and adult patients.Results Among 24 patients,thorax and spinal deformity were found in 19 children(79%),leptosome type existed in 16 children(67%),dolichostenomelia was found in 15 children(63%).The dilation of the aortic sinus was detected in 16 children ((67%),)and the dilations of left ventricle and mitral regurgitation were found in 3 children(13%) with echocardiogram.Conclusions It is critical ascertain the abnormalities in cardiovascular system and give intervention,and it is expected to prolong the patients′ life by slowing down the changes in aortic walls.
