Accreditation of professional titles is a work with which all professionals are prevailingly concerned. In review of the accreditation work since the professional title reform, it has been thought that the Central Professional Title Reform Offices regulations on service seniority and the widely used accreditation methods at present have some drawbacks. Further reform of professional title accreditation is imperative.

Separating the appraisement and engagement of professional titles,an important task in the reform of the personnel system,renders the appraisement of professional titles more objective and fair,thus avoiding the influence of man-made factors in the appraisement of professional titles within an institution.However,there have appeared such problems as high passing rates and great pressure with regard to engagement.Thus the appraisement of professional titles is in need of reform.

Objective To investigate the postoperative complications of pregnant women with two cesarean section.Methods Clinical data of 543 cases of pregnant women with two cesarean section (group A) were retrospective analyzed,and at the same period two spontaneous vaginal delivery in 963 cases(group B),225 cases of pregnant women with the first cesarean delivery add second vaginal delivery(group C) were analyed in contrast.The postoperative close,long-term complications of three different delivery way were censused.Results (1) Postoperative complications:141 cases(26％) in group A,29 cases(3％) ingroup B,27 cases (12％)in group C,and three complications occurrence rate had significant difference (x2 =182.711,29.712,43.040,all P ＜ 0.05).(2) The complications of postpartum bleeding,pelvic adhesions in group A were significantly higher than those of C group(all P ＜0.05) ;And the close complications of postpartum hemorrhage,infection of incision,postpartum fever and the long-term complications of chronic pelvic inflammation,pelvic adhesion in group A,C were significantly higher than those in group B (all P ＜ 0.05).Conclusion The cesarean section is traumatic,which can significantly increase maternal intraoperative,postoperative complications.Clinicians should avoid no indications of cesarean section,reduce the cesarean section rate;For secondary pregnancy after cesarean section,vaginal delivery can be given under the strict observation.

ObjectiveTo investigate the effects of intravenous fentanyl combined with scalp nerve block with ropivacaine on the hemodynamic response to skin incision during craniotomy.Methods43 ASA Ⅰ～Ⅱ patients scheduled for selective frontotemporal craniotomy were randomly assigned into 3 groups: the isoflurane group(group I,n=14), the fentanyl group (group F, n=15) and the fentanyl-ropivacaine group (group B, n=14 ).Anesthetic induction was performed with IV remifentanil 2 μg/kg, propofol 2 mg/kg, and vecuronium 0.1mg/kg. Group F received fentanyl 3 μg/kg 5 min before skin incision .Group B received the same doses of fentanyl prior to skin incision as well as scalp nerve block with 1% ropivacaine before induction. Anesthesia was maintained with isoflurane. The "up and down" method was used to determine MAC-BAR in each group.ResultsThe end-tidal isoflurane concentration blocking sympathetic response to incision in group I, F and B were 2.0%,1.8%,1.0% respectively.The MAC-BAR of group I, F and B were 1.7 MAC,1.55 MAC,0.8 MAC respectively. The end-tidal isoflurane concentration blocking sympathetic response to incision and MAC-BAR of group B decreased obviously compared with that of group I and F(P<0.05).ConclusionIntravenous fentanyl combined with scalp nerve block with ropivacaine can successfully reduce the hemodynamic response to skin incision.

ObjectiveTo determine the effectiveness of scalp nerve block for attenuating intraoperative hemodynamic stress, decreasing anesthetics and postoperative pain in neurosurgical patients.Methods60 adult patients undergoing frontotemporal craniotomies were randomly divided into three groups to receive scalp nerve block with normal saline as control in group A, 0.8% lidocaine combined with 0.13 % menthol in group B, and 1% ropivacaine in group C after intubation. Anesthesia was maintained with isoflurane. Mean arterial pressure (MAP) was controlled within-20%～+10% of the baseline with isoflurane (maximum limitation of isoflurane was 2 times of minimal alveolar air concentration) and intravenous nicardipine (0.5 mg bolus iv). Heart rate was controlled below 100 bpm with esmolol (50 mg bolus iv). Patient controlled analgesia (PCA) with tramadol was used for the postoperative analgesia. MAP, heart rate (HR) and end tidal isoflurane concentration were monitored during craniotomy. Visual analogous score (VAS) was observed after craniotomy.ResultsThe concentrations of end-tidal isoflurane in group A were significantly higher than that in group B and group C. MAP and HR in group A increased significantly than baseline values during operation, especially in skin incision, opening bone,while MAP and HR in group C did not increased significantly than baseline. VAS within 2 h postoperative in group B was significantly lower than that in group A (P<0.05).ConclusionThe scalp nerve block can effectively decrease intraoperative isoflurane concentration, attenuate hemodynamic responses and reduce postoperative pain.

AIM: To investigate the causes and features of anxiety for further understanding of this disorder.METHODS: The theories of anxiety introduced by Freud, Karen Homey and Harry S. Sullivan were analyzed and assessed.RESULTS: Anxiety was emotional experience occurred when an individual anticipated that his/her self-respect was threatened by internal and external stimulus but he felt that he could not cope with such threats. Whereas, it was up to the cognitive evaluation to determine whether such internal and external stimulus threatened self-respect and to identify whether one could handle such threats.CONCLUSION: Stimulation, self-respect, cognitive evaluation and ability are the key factors that determine the anxiety. Treatment of anxiety should not based on medicine, but also carefully consider psychological treatment. Patients should be informed with the nature of this disease so that they have certain self-awareness to improve their ability to handle the threats,correct any misunderstanding, and rebuild cognition.

Objective:To evaluate the value of DSA in diagnosis of intestinal vascular malformation.Methods:The clinical and DSA characters in 8 patients with small intestinal malformation were analyzed.There were 6 males and 2 females.All patients were underwent selective and supper selective superior mesenteric inferior mesenteric or colic artery angiographies.Results:The clinical fectures:1)the main sympton is acute lower gastrointestinal bleeding;(2)the results of conventional examination were generally negative;(3)the hemoglobin was dropped down to 4～6 g/ml in a short period.DSA feactures included:(1)artery-vein fistula;(2)markedly stainning in local small intestinal walls;(3)abnormal hyperplasia and distubance of small vessels.Conclusion:DSA is the most valuable method in diognosis of atute intestinal bleeding.

Forty-five male SD rats were divided into normal group, diabetic control group, and rosiglitazone treatment diabetic group.By the end of 12 weeks, the expressions of pigment epithelium-derived factor(PEDF), matrix metalloproteinase-2 (MMP-2), and transforming growth factor-β1 (TGF-β1) in the kidney were determined by immunohistochemistry and RT-PCR.The results showed that rosiglitazone decreased the increased kidney weight/body weight ratio, serum creatinine, blood ureanitrogen, urinary albumin excretion, triglyceride levels in diabetic rats (all P＜0.01).Rosiglitazone prevented the decreasing of protein expressions of PEDF and MMP-2 and the increasing of protein expression of TGF-β1 (all P＜0.01).PEDF mRNA showed a similar change,suggesting that renoprotection of rosiglitazone on diabetic rats may be mediated through regulating the expressions of PEDF, MMP-2, and TGF-β1.

Sarcopenia is a major clinical characteristic of cancer cachexia .The main pathophysiologic mechanism of sarcopenia related to cancer cachexia is abnormality between anabolic and catabolic pathways of muscle mediated by chronic inflammation .The major treatments for sarcopenia in cancer cachexia currently in-clude hormone therapy , nutrition support , exercise therapy , and other medications , which could not effectively prevent muscle loss or enhance muscle function .Better understanding of the pathogenetic processes of cancer cachexia-related sarcopenia may help in finding targets for an effective therapy .

This study demonstrated with the immunocytochemical ABC method that thedistribution pattern of TH,5-TH,SP,L-ENK and OXY immunoreactive fiberswere alike in the intermediate zone of the thoracic and upper lumbar spinal cord.These fibers located in the lateral funiculus,lateral horn,intermediate gray and thearea surrounding the central canal,forming a transversal fiber band with most ofthe fibers in the lateral horn.In the lateral horn,TH,5-HT,SP and L-ENKimmunoreactive fibers and terminals aggregated in fiber clusters and numerous fib-ers made up a longitudinal bundle running through the fiber clusters.These immuno-reative fibers and terminals surrounding the central canal and distributed mainly dorsalto it.TH and 5-HT fibers accumulated in midplane where some fibers ran in alongitudinal fiber bundle and bilateral fibers and terminals distributed sparsely.SP and L-ENK fibers and terminals were relatively less in the midplane whiledense laterally.All kinds of the immunoreactive fibers were found close to theependyma.Two small 5-HT fiber bundles ran parallel and lateral to the centralcanal and a small SP fiber bundle ventral to it.Moderate immunoreactive fiberswere found periodically in the intermediate gray and formed distinct bands to linkfiber clusters in the lateral horn and fibers dorsal to the central canal.The imm- unoreactive fibers in lateral funiculus accumulated near the lateral horn and mostdensely in upper thoracic cord.OXY-containing fibers were much less than theothers,thus obvious fiber clusters,longitudinal bundle or transversal bands had notbeen found.In general,the distribution pattern of some monoaminergic and pepti-dergic fibers in the intermediate zone was provided with a laddershaped configura-tion.The two longitudinal immunoreactive fiber bundles——dorsal to the centralcanal and within the lateral horn,located medial and lateral in the spinal grayrespectively,and the transversal bands appeared periodically in the intermediate graybridging between the two longitudinal bundles.This configuration of immunorea-ctive fibers coincided with nuclear regions which contained preganglionic sympatheticneurons as well as their dendrites.
