Objective To determine the timing of surgical treatment for pancreatic pseudocyst(PPC) secondary to severe acute pancreatitis(SAP). Methods Twenty-seven cases of PPC appearing 4-8 weeks after SAP were treated with internal drainage were included in group A.Of the 27 cases,10 received cystojejunostomy by stapler.In other 30 cases in group B,surgical procedures were performed 24 weeks after the formation of the cyst.Several parameters were compared between the 2 groups.Results The incidence of anastomotic leakage,average duration of hospitalization and mean fee for hospitalization were significantly lower in group A than in group B(P0.05).Emergency surgical treatments were performed in 5 patients in group B due to complications of introcystic hemorrhage(1 patients),introcystic infection(2 patients) and cystic rupture(2 patients).Conclusions Accurate diagnosis and early surgical treatments are effective and safe for treatment of PPC secondary to SAP.Meanwhile,they might be helpful for avoiding complications of introcystic infection,introcystic hemorrhage and cystic rupture.

BACKGROUND:Articular capsule ligaments can lead articular surface to move normally and limit the excessive movement, especially to prevent any non-physiological movement. They are the important structures for stabilizing hip joints. It was previously thought that articular capsule should be routinely resected in the total hip arthroplasty (THA). OBJECTIVE: This study was designed to investigate the effect of retaining articular capsule in THA through posterior approach on maintaining hip stability. DESIGN, TIME AND SETTING: This study, a retrospective case analysis, was performed on 61 patients with femoral neck fracture, who received treatment in the Department of Orthopedics, Xiangya Second Hospital of Central South between January 2005 and December 2006. PARTICIPANTS: Twenty-nine patients who underwent THA with retaining articular capsule from January to December 2006 were included as retaining group, and thirty-two patients who underwent THA with routine resection of partial articular capsule were included as routine group. The two groups were kept identical in case selection, prosthesis selection, post-surgery processing and operators. METHODS: Four holes were drilled on greater trochanter on the proximal femoral bone. The superior part of articular capsule valve was sutured to the superior part of original articular capsule using No.1-0 absorbing thread, then sutured to base of femoral neck in mattress manner, and the suture was not ligated. The inferior part of articular capsule valve was sutured to the inferior part of original articular capsule using another suture. And the suture passed through two bone holes on base of femoral neck. The lower limbs were externally rotated and the suture was ligated. Subsequently, the excised extortor was repaired. Prior to and subsequent to suture, hip was slowly bent for 90° and femur was internally rotated for45°to investigate the suture of articular capsule on strengthening articular stability. MAI OUTCOME MEASURES: Operation time, bleeding volume and hip dislocation after THA. RESULTS: The operation time and bleeding volume were lower in the retaining group than in the routine group (P < 0.05). After THA, hip dislocation did not occur in any patients in the retaining group but occur in 2 patients (6.2%) in the routine group. Statistical tests could not be performed due to less data, resulting in no statistical significance.CONCLUSION: There has been no precise conclusion about the effects of retaining articular capsule or not on hip stability.But retaining articular capsule shortens operation time, reduces intrao-perative bleeding, unable raise operation risk, and re-establishes hip soft tissue balance.

Objective:To study the effect of repeated transient ischemic attacks(TIAs)on cumulative injury of cognitive function.Methods:The cognitive condition of 42 patients with repeated TIAs were assessed after each TIA using the event related potential,modified version of Wisconsin card sorting test,trail making test,digit span task,and verbal fluency test.The cognitive condition was compared and analyzed after different attack times.Results:There were significant differences among the cognitive condition after different attack times,latency and amplitude of P300,and detection rate of mild cognitive impairment.With the increase of the attack times,cognitive impairment aggravated gradually,and the detection rate of mild cognitive impairment increased gradually.Conclusions:Repeated TIAs have cumulative injury on cognitive function.The prevention and treatment of cerebral ischemia may become an important approach in decreasing cognitive impairment.

Objective To explore the feasibility of right ventricular outflow tract (RVOT) septal pacing. Methods Fifty-two patients implanted with pacemaker were randomly divided into two groups. One group underwent the RVOT septal pacing with active fixation electrodes (active fixation electrodes group, 22 cases),and the other group underwent the right ventricular apical pacing with passive fixation electrodes (passive fixation electrodes group, 30 cases). The parameters of two groups in operation were recorded. Results The successful rate of RVOT septal pacing was 100%, active fixation electrodes group took more time to plant electrodes and expose in X-ray than passive fixation electrodes group [ (56.13±1.18)min vs (15.42±1.24) min, (18.77±6.14) min vs (10.12±8.14) min, P<0.05]. The width of the QRS wave of active fixation electrodes group was narrower than that of passive fixation electrodes group [(0.14±0.02)ms vs (0.16±0.04) ms, P< 0.05]. The parameters of two groups were stable in follow-up period and none of electrodes was extracted. Conclusion The usage of active fixation electrodes in patients with RVOT septal pacing is feasible and safe.

Space-time is extremely attached importance to in the thinking of recognizing diseases and syndrome differentiations in TCM. For instance, internal/external and upper/lower in Neijing, are the concept of compartmentalization of the tissue and structure in the body, also are the mechanism of recognizing generations and changes of diseases by combining both space and time organically. Moreover, the thinking of upper/lower and internal/external syndrome differentiations and treatments in TCM constitute a relatively completely space-time system, which are in favor of systematicness and integrality of syndrome differentiation and analysis, and then are usually used clinically. Therefore, upper/lower syndrome differentiation is the medical concept deriving from yin/yang. However, it exceeds mechanical space-time concept, also has the meaning of‘principle’ to guide syndrome differentiation and treatment. Thus, raising an issue that blending the thinking of upper/lower syndrome differentiation into eight principles and other methods of syndrome differentiation, in order to make methods of syndrome differentiation more practical.
