ObjectiveTo analysis the subsets of the lymphocyte and dendritic cells (DC) in peripheral blood in patients with neurosyphilis and investigate the relationship between these cells and onset of neurosyphilis.MethodsThe subsets of CD4+T cells as well as DCs and the counts of CD4+T and CD8+T were analyzed by flow cytometry with immunofluorescent staining in 8 patients with neurosyphilis and 10 healthy controls.ResultsIn peripheral blood of neurosyphilis patients the proportion of CD4+T cell was significantly higher than that in the normal controls ( P<0.01); the proportion of CD8+T cell was significantly lower than that in the normal controls ( P<0.05). The proportion of Th1, Th2 and the ratio of Th1/Th2 in neurosyphilis patients was (14.12±5.12)%, (1.52±0.88)% and (12.05±5.62), respectively. In normal controls, it was (26.10±4.98)%, (0.99±0.35)% and (31.62±16.62) respectively. The expression of Th1 and the ratio of Th1/Th2 in neurosyphilis patients was significantly lower than the normal controls (P<0.05). The proportion of DC1 and DC2 in neurosyphilis patients was not significantly different from that in normal controls ( P>0.05). There was a significant correlation between DC1 and Th1, DC2 and Th2 in the neurosyphilis patients ( P<0.051), but no correlation between the proportion of DCs and the ratio of Th1/Th2 ( P>0.05).ConclusionThe cellular immune function of neurosyphilis patients may be inhibited, and there is no relationship between the proportion of DCs subset and unbalance of Th1/Th2.

Serum triglyceride ( TG ) , total cholesterol ( TC ) , low density lipoprotein cholesterol ( LDL-C) , high density lipoprotein cholesterol ( HDL-C) , uric acid ( UA) levels and fasting blood glucose ( FBG) were measured in 67 patients with chronic spontaneous urticaria ( CSU ) and 66 healthy subjects ( controls).Results showed that the rates of increased serum TG and FBG levels in CSU patients were higher than those in controls ( 19% vs.6%,χ2 =5.309, P <0.05; 12% vs.1%,χ2 =4.194, P <0.05, respectively);however, there were no significant differences in abnormal rate of TC(7%vs.3%) , LDL-C (4%vs.1%), HDL-C(6%vs.3%)and UA(6%vs.1%) between CSU patients and healthy controls(all P>0.05).The rate of rising FBG in CSU patients accompanied by angioedema(4/9)was higher than that in CSU patients without angioedema(7%,χ2 =7.181,P<0.05).

Objective Acute type A aortic dissection associated pregnancy severely threatens the lives of both the mother and her ferus.We retrospectively reviewed our clinical experience with this life-threatening condition in six cases.Methods Between January 2007 and February 2012,6 women with acute type A aotic dissection associated pregnancy were treated by our group,with an average of 3 1 years (range 24 -37 weeks)and a mean gestation weeks of 24.5 (range,12 -38 weeks ).The etiology was Marfan syndrome in 4 cases and gestational hypertension in 2.The pathology was the modified Stanford type A3S in I case,A2C in 2 and A3C in 3.- Five patients were treated surgically and 1 medically.Surgical operations were performed under hypothermic cardiopulmonary bypass or deep hypothermic circulatory arrest,including Bentall procedure in 1case,Bentall + Sun's procedure in 2,ascending aortic replacement + Sun's procedure in 2.Results The woman treated medically and her fetus died from aortic rupture 9 days after admission.The cardiopulmonary bypass and cross clamp time and circulatory arrest time averaged 167 rninites(range,75 -210 minites) and 98 minites(range,83 - 145 minites) and 23.5minites(range,19 -27 minutes),respectively.Five patients treaed surgically survived the operation.Three fetuses survived rand two fetuses died.After a mean follow-up of 2.2 years (range,1 - 3.5 years ),5 patients were doing well.CT angiogram detected nonmal aortic and valvular structures,with no signs of distal dilation.Three babies were normal in development and neurocognitive functios.Conclusion Palients with aortic dissection associated with pregnancy should be operated on ugently and medical treatment carries high risks of aortic rupture and maternal and fetal death.Methods of surgical repair,peffusion techniques and delivery should be chosen based on the underlying aortic pathology and gestational age,so as to maximize the safety of the mother and her baby.

Objective To reassess the treatment of Bosniak category Ⅱ-Ⅲ renal cyst.Methods Sixty-eight cases of Bosniak category Ⅱ-Ⅲ renal cyst were operated from 2005 to 2008 in our institute.The average patient age was 40 years with the average renal cyst diameter of 5.1 cm.There were 37 left lesions and 31 right lesions with 31 cases of category Ⅱ (including 13 cases of category Ⅱ F) and 37 cases of category Ⅲ.Renal unroofing were performed in 49 cases with 9 cases found malignant and followed by radical nephrectomy,19 cases were diagnosed as malignancy preoperatively and nephron sparing surgery or radical nephrectomy were performed in these cases.Results Malignant lesions were found in 21 cases and benign lesions were found in 47 cases.The malignant rate was 9.7％ in category Ⅱ (15.4％ in category Ⅱ F),48.6％ in category Ⅲ.Nine cases were diagnosed benign preoperatively but confirmed malignancy after operation; 7 cases were diagnosed malignancy preoperatively but confirmed benign after operation.Forty-two cases were followed up for 8-65 months with 15 cases of malignancy and 27 cases of benign lesions.The recurrence of renal cyst occurred in 6 cases of benign lesions and recurrence and metastasis occurred in 3 cases of malignancy in 1-5 years.Conclusions It is difficult to draw a therapeutic principle for Bosniak category Ⅱ-Ⅲ renal cyst because of the uncertainty of the lesion.Partial nephrectomy or renal cystectomy is a good choice in the treatment of Bosniak category Ⅱ-Ⅲ renal cysts.

Objective To investigate the safety and efficacy of radical nephrectomy plus inferior vena cava thrombectomy,and to evaluate the efficacy of preoperative temporary inferior vena cava filter placement and intraoperative application of liver transplantation techniques to reveal the inferior vena cava in order to avoid tumor thrombosis shedding and embolism.Methods The data of 42 cases (January 2004 to December 2010) of renal cell carcinoma with subdiaphragmatic thrombus were analyzed retrospectively.All these patients underwent radical nephrectomy plus inferior vena cava thrombectomy.Patients were implanted temporary inferior vena cava filter as preoperative routine.Patients with the tumor thrombi behind the liver were applied liver transplant techniques to free and turn liver to the left in order to reveal inferior vena cava,block blood flow according to priority and then finish the inferior vena cava thrombectomy.The filter was removed postoperatively on the same day,and the patients were followed up as routine.Results The operation of the 42 cases was successful without symptomatic tumor thrombus embolism perioperatively,while 1 case died of severe postoperative lung infection.The average operation time was 220 min (130-320 min),blood loss was 750 ml (200-2500 ml),and 12 cases had blood transfusion with an average of 800 ml (400-2000 ml).Forty-one cases were followed up with an average period of 36 months (6-60 months).Among the 37 cases without preoperative tumor metastasis,15 cases had metastases and 22 cases had disease-free survival.Conclusions Nephrectomy and inferior vena cava thrombectomy could be safe and effective for renal cell carcinoma with subdiaphragmatic thrombosis.Preoperative temporary inferior vena cava filter placement and intraoperative application of liver transplantation techniques to reveal the inferior vena cava can be effective to prevent tumor thrombosis shedding and embolism and improve surgical safety.

Objective To assess the clinical efficacy of percutaneous iliosacral screwing versus reconstruction plating in the treatment of pelvic posterior ring fractures of Tile C.Methods The authors retrieved the randomized controlled trials (RCTs) and clinical controlled trials (CCTs) comparing percutaneous iliosacral screwing versus reconstruction plating for Tile C pelvic posterior ring fractures from the Cochrane library,Medline,Embase,CNKI,Wanfang Data and Chinese Biomedical Database by computer and from major Chinese orthopedic journals by hand.Qualified data were extracted by statistical software Revman 5.2 for meta-analysis.Results 334 cases were included in this Meta-analysis from one RCT and 3 CCTs.Of them,162 underwent percutaneous iliosacral screwing and 172 reconstruction plating (including 66 cases of percutaneous reconstruction plating and 106 ones of anterior reconstruction plating).There was no significant difference between percutaneous iliosacral screwing and reconstruction plating in operation time (P =0.16).Percutaneous reconstruction plating consumed significantly less operation time than anterior reconstruction plating (P ＜ 0.001).Percutaneous iliosacral screwing decreased significantly incision length and intraoperative blood loss than both methods of reconstruction plating (P ＜ 0.001),but significantly increased times of X-ray exposure than percutaneous reconstruction plating (P ＜ 0.001).There were no significantly differences in the good to excellence rates by Matta scores and Majeed scores between percutaneous iliosacral screwing and percutaneous reconstruction plating (P ＞ 0.05),but percutaneous iliosacral screwing performed significantly better than anterior reconstruction plating (P ＜ 0.001).Percutaneous reconstruction plating led to significantly fewer postoperative complications than anterior reconstruction plating (P ＜ 0.001) but similar incidence of postoperative pain at the sacroiliac joint compared with percutaneous reconstruction plating (P =0.30).Conclusion Compared with anterior reconstruction plating,pereutaneous iliosacral screwing and percutaneous reconstruction plating may lead to better clinical efficacy and fewer complications.Percutaneous iliosacral screwing may be superior in incision length and intraoperative blood loss,but it requires more intraoperative X-ray exposure and more demanding technical skills.

The clinical data of 7 patients with porokeratosis (PK) were analyzed retrospectively.In 7 PK patients, 4 cases were disseminated superficial actinic porokeratosis (DSAP),1 case was disseminated superficial porokeratosis (DSP),1 case was giant porokeratosis (GP) and 1 case was hypertrophic porokeratosis (HP).The characteristic cutaneous manifestations were annular well-circumscribed keratotic plaques with slightly atrophic center and elevated border.All patients shared a common histological hallmark, the cornoid lamella.Four cases of DSAP patients had family medical history, consistent with autosomal dominant inheritance.DSP, GP and HP patients denied family medical history.Diagnosis of PK should be based on clinical manifestations, family medical history and histopathological examination.

An analysis of the time pattern of outpatients visits to our hospital from 1997 to 2000 led to the discovery of the variation pattern of each outpatient departments workload. This discovery has enabled the managers of the hospital to rationally deploy the manpower and material resources of various departments, make full use of limited resources, readjust the working hours and shifts of different kinds of staff, and work out a flexible system of working hours which is more scientific and more convenient to patients. Implementation of such a system has ensured that prompt delivery of medical service is accessible to patients even at the peak of visiting hours. Hence the reduction of patients time of waiting and the provision of a scientific guarantee for establishing a quality, efficient, low consumption and fast outpatient service system, meeting the medical needs of patients to the maximum and enhancing work efficiency.

ObjectiveTo study the risk factors of renal artery pseudoaneurysm (RAP) following partial nephrectomy.MethodsOpen partial nephrectomy was performed on a total of 464 cases of renal cell cancer from July 2003 to May 2010. Five patients ( 1.1％ ) had postoperative hemorrhage from RAP.The surgery technique of the open partial nephrectomy, the clinical presentation, imaging findings and treatment of RAP were reviewed. The anatomical characteristics of these five renal tumors on enhanced CT were quantified using the R.E.N.A.L. Nephrometry Score System.ResultsAll five cases were male, two had tumors on the left side and three on the right side. Median tumor size was 3.6 cm ( range from 2.5 to 5 cm; Radius score 1 - 2). Four tumors were exophytic of these, three had a major endophytic component (≥50％) deep in the parenchyma (Exophytic/endophytic score 2 ), one was entirely endophytic (score 3 ). The distance of all the tumors to the collecting system was ≤4 mm ( Nearness score 3 ). Four of the five tumors were across the polar line and/or renal axial midline ( Location score 3 ). The other tumor was located under the lower pole ( Location score 1 ) but close to the renal hilar. All patients presented with delayed gross haematuria and decreasing hemoglobin occurred on mean postoperative day 12 (3 -23 day). Four patients complained of flank pain, two of which had signs of hypovolemia requiring blood transfusion. The diagnosis was confirmed by the contrast medium-enhanced CT and selective angiography, and RAP was found most commonly arising from the segmental branch of renal artery. Superselective microcoil angioembolization was successfully performed in four cases, once in three cases and twice in the remaining case. The procedure failed in one patient and a nephrectomy was done. At a mean follow-up of 21 months (12 -30) , all patients had normal renal function without evidence of recurrence.ConclusionsRAP should be considered in all patients who had delayed hematuria after partial nephrectomy. A central, deep tumor and its relationship to the segmental branch of renal artery could be an important risk factor for this complication. Choosing the case properly for partial nephrectomy and suturing the transected vessels and the defect of parenchymal correctly could reduce occurrence of this serious complication. Early use of selective angioembolization could be a primary choice of treatment.

OBJECTIVETo investigate the mRNA expressions of the TNF adapter proteins, including TNF receptor-associated death domain protein (TRADD), Fas-associated death domain protein (FADD), receptor-interacting protein 1 (RIP-1) and TNF receptor-associated factor-2 (TRAF-2) in peripheral blood mononuclear cells (PBMCs) of lupus nephritis (LN) patients of various TCM asthenia syndromes. Methods Fifty-one inpatients with LN were differentiated according to TCM syndrome differentiation, 13 cases of yin-deficiency with inner heat syndrome (A); 26 cases of both qi-yin deficiency syndrome (B), 12 cases of Pi-Shen yang-deficiency syndrome (C). Peripheral venous blood samples from the 51 LN patients and 17 healthy subjects were collected to separate PBMCs. The mRNA expressions of TNF adapter molecules (TRADD, FADD, RIP-1 and TRAF-2), as well as Caspase-3 and interleukin-1beta (IL-1beta) were analyzed by quantitative real-time PCR and the differences among them were compared.

RESULTS(1) As compared with the healthy subjects, expression of TRADD mRNA in patients of syndrome A, B and C was lowered to 0.54, 0.32, and 0.38-fold, respectively (P < 0.05, P < 0.01), showing insignificant difference among the three syndromes; (2) FADD mRNA lowered to 0.79, 0.62, and 0.72-fold respectively, only with significance shown in syndrome B (P < 0.05); (3) RIP-1 mRNA lowered to 0.79, 0.50, and 0.60-fold respectively with significance shown in syndrome B and C (P < 0.01, P < 0.05), and insignificant difference was shown among the three syndromes; (4) TRAF-2 lowered to 0.70, 0.52, and 0.50-fold respectively (P < 0.01, P < 0.01, P = 0.07), significance shown in syndrome B and C (P < 0.01), but with insignificant difference among the three; (5) Caspase-3 elevated in all patients of the three syndromes (all P < 0.01); (6) IL-1beta in syndrome A was apparently lower ed to the normal range and also lower than that in the other two syndromes (both P < 0.05).

CONCLUSIONSExpressions of TRADD, FADD, RIP-1 and TRAF-2 mRNA decreased in all the patients of various TCM asthenia syndromes, the decrement in patients of syndrome B and C was lesser than that in syndrome A. These abnormal low expressions of signal proteins might be the substantial bases for asthenia syndromes of LN patients, and the apoptotic signal mediated by them may involve in the formation of asthenia syndrome in LN.
