ABSTRACT
Objective:To analyze the predictive value of enhanced MRI in the outcome of prolapsed and sequestrated lumbar disc herniation through a retrospective analysis.Methods:A retrospective analysis of the data of 64 patients with prolapsed and sequestrated lumbar disc herniation from January 2015 to December 2018, including 38 males and 26 females; age 35.72±12.44 years (range, 22-64 years) ; 43 cases of prolapsed type, 21 cases of sequestrated type. Conservative treatment was the first choice for all patients, in case of surgical indications during the treatment, percutaneous endoscopic lumbar discectomy or fenestration discectomy will be performed. Enhanced MRI was performed at the first and last inspections, the volume of the protrusion, the thickness of rim enhancement (Tr), and the extent of rim enhancement (Er) were measured and calculated at the same time. According to the ring around the protrusion, the size of the rim-enhancement area was divided into type I-III; then compared the relationship between the rim-enhancement signal differentiation and the resorption rate of protrusions, and the correlation between Tr, Er values and the resorption rate of protrusions during the initial inspection.Results:Among the 64 patients, 42 patients completed conservative treatment, and 22 received surgical treatment. According to the rim-enhancement signal differentiation, 23 cases were treated conservatively for type I, 3 cases were treated by surgery; 16 cases were treated for type II conservatively, 7 cases were treated by surgery; 3 cases were treated for type III conservatively, and 12 cases were treated by surgery. All patients were followed up for 12 to 34 months. Among 42 conservatively treated patients, The volume of the protrusion before treatment was 2 645.67±690.86 mm 3, and the volume of the protrusion after treatment was 842.76±573.35 mm 3. The volume of protrusions before and after treatment was statistical significance ( t=11.897, P<0.001), Tr was 1.38±0.83 mm, and Er was 73.08%±34.39%, the resorption rate of protrusions was 65.10%±24.50%, and 39 cases (92.86%, 39/42) reached the standard for protrusion resorption (resorption rate ≥30%); 23 cases of type I , the resorption rate was 76.54%±18.62%; 16 cases of type II had an resorption rate of 56.81%±21.44%; 3 cases of type III had an resorption rate of 21.58%±12.19%. The resorption rate of type III were compared by single factor analysis of variance, and the difference was statistically significant ( F=12.885, P<0.001); 32 cases of both type I and II (82.05%, 32/39) had significant resorption (resorption rate ≥50%), and no case of type Ⅲ had significant resorption, comparing with type I and II, the difference was statistically significant ( P=0.010); Tr was positively correlated with resorption rate ( r=0.569, P<0.001), Er was positively correlated with resorption rate ( r=0.677, P<0.001). Conclusion:Under close clinical observation, parts of the prolapsed or sequestrated lumbar disc herniations can be conservatively treated, and the herniated disc can be resorption in many people and the clinical symptoms were alleviated. Rim-enhancement signal differentiation by enhanced MR has a better predictive value for the outcome of the herniation, type I is more prone to resorption, preferred conservative treatment, type Ⅲ is not easy to resorption, preferred surgery treatment, and the higher thickness of rim enhancement, the greater extend the rim-enhancement, the more prone to resorption phenomenon.

ABSTRACT
Objective: To summarize the peri-operative management experience of pulmonary endarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: A total of 56 CTEPH patients received PEA in our hospital from 2015-01 to 2016-11 were retrospectively analyzed. Our study was focused on the medication in respiratory and circulatory system during ICU stay, peri-operative application of vasoactive drug and target drug to pulmonary hypertension (HP), usage of ventilators, mechanical assisted devices and other management experiences. Results: No peri-operative death occurred. There were 2/56 (3.6%) patients with lung reperfusion, 2 (3.6%) with PH crisis. Compared with pre-operation, the post-operative pulmonary artery hemodynamics parameters were improved as right heart catheter measured pulmonary artery systolic pressure (PASP) decreased from (85.05±22.40) mmHg to (36.83 ±17.21) mmHg and pulmonary vascular resistance decreased from (773.84±342.95) dyn·s·cm-5 to (293.59±214.95) dyn·s·cm-5. Post-operative oxygen saturation was maintained at (95-100) % in all patients. Echocardiography found that PASP from pre-operation (85.03±25.78) mmHg decreased to (39.44±19.24) mmHg at follow-up period, P<0.01.Conclusion: A comprehensive peri-operative management of PEA was helpful to improve pulmonary hemodynamics in CTEPH patients; meanwhile, effective prevention and treatment of severe complication could obviously reduce peri-operative mortality.
ABSTRACT
ObjectiveTo investigate the incidence rate and risk factors for the complications after laparoscopic splenectomy in patients with portal hypertension. MethodsThe clinical data of 83 patients with portal hypertension, who were admitted to our hospital and underwent laparoscopic splenectomy from June 2009 to December 2014, were analyzed retrospectively. The incidence rate of the complications was analyzed using the Clavien-Dindo classification system and the risk factors for the complications were analyzed using chi-square test and logistic regression method. ResultsThe incidence rate of postoperative complications was 24.10% (20/83). According to the Clavien-Dindo classification system, the numbers of patients with grade Ⅰ, Ⅱ, Ⅲ, Ⅳ, and Ⅴ complications were 5, 3, 10, 2, and 0, respectively. The patients undergoing total laparoscopic splenectomy had a significantly higher incidence rate of postoperative complications than those undergoing hand-assisted laparoscopic splenectomy (32.59% vs 15.00%, χ2=3.966, P=0.046). According to the univariate analysis, the Child-Pugh class, application of the hand-assisted device, gastroesophageal vein ligation, and American Society of Anesthesiologists (ASA) grade were all risks factors for the postoperative complications (all P＜0.05). Further analysis using multiple logistic regression illustrated that Child-Pugh class B and ASA grade Ⅲ were independent risk factors for the postoperative complications (OR=0.328, 95%CI: 0.129~0.834, P＜0.05; OR=0.294, 95%CI: 0.150~0.573, P＜0.05). ConclusionPatients with portal hypertension undergoing laparoscopic splenectomy have a high incidence of postoperative complications and the occurrence of the complications is closely associated with the Child-Pugh class and the ASA grade.
ABSTRACT
ObjectiveTo observe the effects of different suture techniques on complications after choledochojejunostomy. MethodsA retrospective analysis was performed on the clinical data of 162 patients who underwent choledochojejunostomy from January 2005 to December 2014 in our hospital. The patients were divided into group A undergoing simple interrupted suture (n=68), group B undergoing simple continuous suture (n=45), and group C undergoing parachute type continuous suture (n=49). The intraoperative conditions and postoperative complications were compared between the three groups. Comparison of continuous data between the three groups was made by ANOVA and pairwise comparison between any two groups was made by LSD t-tests; comparison of categorical data between the groups was made by chi-square test. ResultsThe anastomosis time and the rate of T-tube insertion showed significant differences between the three groups (P＜0.05). Groups B and C had significantly shorter anastomosis time than group A(P＜0.001), but there was no significant difference in the anastomosis time between groups B and C (P＞0.05). Among the three groups, group A had the highest rate of T-tube insertion; group B had the second highest rate; group C had the lowest rate. Significant differences were found between any two groups in the rate of T-tube insertion by pairwise comparison (P＜0.05). However, there were no significant differences between the three groups in the incidence rates of postoperative bile leakage and choleperitonitis (P＞0.05). There was significant difference in biliary stricture between the three groups in the follow-up examination 6 months after surgery (P＜0.001) and the differences analyzed by pairwise comparison were also significant (P＜0.05). Among the three groups, the degree of biliary stricture in the group A was the highest and that in the group C was the lowest. ConclusionParachute-type continuous suture is a fine suture technique for choledochojejunostomy, which can reduce the anastomosis time, the rate of T-tube insertion, and the degree of biliary stricture.

ABSTRACT
Objective To investigate the expression of human papillomavirus (HPV) L1 protein in lesional tissue of condyloma acuminatum and its clinical significance.Methods Forty-three patients with condyloma acuminatum were included in this study,and received CO2 laser therapy.Tissue samples were resected from the lesions of these patients at their first visit before treatment.Immunohistochemistry was used to determine the expression of HPV L1 protein in these samples.Follow up was carried out once every 2 weeks for 3 months to assess the recurrence rate and frequency in these patients after treatment.Results HPV L1 protein was detected in 83.72％ (36/43) of these tissue samples.The expression rate of HPV L1 protein decreased sequentially from patients infected with HPV 6/11,patients with both HPV 6/11 and 16/18,to those with HPV16/18 (x2 =17.90,P ＜ 0.01).During the 12 weeks of follow up,the recurrence rate was 69.77％ (30/43) with the average number of recurrence of 2.16.There was a sequential reduction in the recurrence rate and number from patients with strong expression of HPV L1 protein,to those with moderate expression,slight expression and negative expression (x2 =8.02,46.92,P ＜ 0.05 and 0.01,respectively).The expression intensity of HPV L1 protein was negatively correlated with the recurrence rate and frequency (rs =-0.429,-0.696,respectively,both P ＜ 0.01).Conclusion HPV L1 protein may serve as a helpful molecular biomarker for the prediction of prognosis and recurrence of condyloma acuminatum.
ABSTRACT
Objective To investigate the expression of CD133 protein in primary lesions of hepatocellular carcinoma (HCC) and its clinical significance.Methods The expression of CD133 protein in 190 patients with HCC was detected by immunohistochemical staining ABC method.The correlation of CD133 protein expression with the clinicopathologic parameters and features after operation was analyzed.Results The expression positive rate of CD133 protein in cancer tissues was 22.1％ (42/190).There was significant correlation between the expression of CD133 protein and tumor differentiation (P ＜ 0.001),micro vessel invasion (P =0.016) and hepatitis B virus infection (P =0.024).Univariate analysis of factors demonstrated that differentiation level,lymph node,macro vessel invasion,micro vessel invasion,TNM stage and CD133 expression were correlated with disease-free survival after surgery (all P ＜ 0.05).Multivariate analysis of factors demonstrated that both CD133 expression and micro vessel invasion were independent prognostic factors of disease-free survival after surgery.Prognostic analysis demonstrated that the disease-free survival of CD133 positive group was significantly lower than that of CD133 negative group.Conclusion The CD133 protein expression in HCC tissues is related with development,metastasis and prognosis of HCC.
ABSTRACT
Objective To evaluate the performance of an improved skin prick test in infantile eczema.Methods A self-controlled study was carried out in 248 infants with eczema.Improved and conventional skin prick tests were conducted with 8 allergens on the left and right flexural forearm of the subjects,respectively.Results Positive results of skin prick test were found in the left flexural forearm of 38.3％ of the infants,and in the right flexural forearm of 38.7％ of the infants,with no significant difference between the two methods in the detection rate of allergens (P ＞ 0.05).The most common sensitizing allergens were house dust mite and Dermatophagoides culinae as shown by both methods.Conclusions The improved skin prick test displays an acceptable performance with simple and safe procedure in the detection of allergens in infants with eczema,and can provide reliable evidence for clinical diagnosis.
ABSTRACT
Objective To estimate the effect of bacille calmette-guerin polysaccharide nucleic acid(BCG-PSN)on skin prick test(SPT)reactions,and to assess the clinical efficacy and therapeutic mechanism of BCG-PSN combined with mizolastine,in patients with chronic idiopathic urticaria.Methods A non-randomized,openlabel clinical trial was carried out.Totally,168 patients with chronic idiopathic urticaria were divided into 2 groups to be treated with mizolastine 10 mg once a day combined with BCG-PSN injection at a dose of 2 ml every other day(experiment group,n =85)or mizolastine 10 mg once a day only(control group,n =83).All the patients underwent SPT,and were evaluated by symptom score at the baseline and after 12 weeks of treatment.Statistical analysis was performed by using the SPSS 10.0 software,t test and Chi-square test were used to analyze the intra-and inter-group differences in symptom score reducing index(SSRI)and SPT results.Results After 12-week treatment,SSRI was significandy higher in the experiment group than in the control group(0.92 ± 0.33 vs.0.74 ± 0.35,t =2.39,P ＜ 0.05).In the experiment group,50 patients were cured,28 patients received a marked response,with a total response rate of 92.0％;meanwhile,32 patients were cured and 30 patients received a marked response in the control group with a total response rate of 74.6％;there was a significant difference in the total response rate between the experiment group and control group(x2 =5.62,P ＜ 0.05).The percentage of positive SPT to Dermatophagoides pteronyssinus and Dermatophagoides farinae was 24.7％ and 17.6％ respectively at the baseline,9.4％ and 5.9％ respectively after treatment,in the experiment group,24.1％ and 16.9％ respectively at the baseline,24.1％ and 15.7％ respectively after treatment,in the control group.Significant differences were observed in the percentage of positive SPT between the control group and experiment group after treatment(x2 =5.82,P ＜0.05),but not at the baseline.A statistical decrease in the percentage of positive SPT was induced by the combined therapy with BCG-PSN and mizolastine(x2 =4.56,P＜ 0.05),but not by mizolastine alone.Conclusions BCG-PSN combined with mizolastine appears superior to mizolastine alone in the treatment of chronic idiopathic urticaria,with a decrease in the percentage of positive SPT reactions and in the sensitivity to allergens.
ABSTRACT
ObjectiveTo determine the protein and mRNA expression levels of interleukin-17 (IL-17) and proportions of Th17 cells in peripheral blood of patients with atopic dermatitis (AD),and to analyze their clinical significance.MethodsVenous blood samples were obtained from 63 patients with AD and 30 normal human controls.Enzyme linked immunosorbent assay was performed to measure the plasma level of IL-17 protein,real time fluorescence reverse transcription (RT)-PCR to detect the mRNA expression level of IL-17 in peripheral blood,flow cytometry to determine the percentage of Th17 cells in peripheral blood mononuclear cells(PBMCs).Spearman's rank correlation analysis was performed to assess the relationship of peripheral blood Th17 cell percentage and IL-17 levels with disease severity in patients with AD.Results The percentage of Th17 cells in PBMCs was 1.83％ ± 0.47％ in patients with acute AD,significantly higher than that in normal human controls (0.85％ ± 0.45％,t =4.128,P ＜ 0.01 ) and in patients with chronic AD ( 1.12％ ± 0.69％,t =2.439,P ＜ 0.05).There was a significant increase in the plasma level (98.37 vs.63.75 ng/L,U =168,P ＜ 0.05) and mRNA expression level of IL-17 in peripheral blood in patients with AD compared with normal controls.Both the Th17 cell percentage and plasma IL-17 level were positively correlated with eczema area and severity index(EASI) score in patients with AD (r =0.681,P ＜ 0.01;r =0.427,P ＜ 0.05).ConclusionsThere is an elevated proportion of Th17 cells and an abnormal expression of IL-17 protein and mRNA in peripheral blood from patients with acute AD,which are positively correlated with disease severity,implicating the possible roles of IL-17 and Th17 cells in the pathogenesis of AD.

ABSTRACT
Objective To investigate the effects of the memory intervention on dysmnesia of elder people in 6 months as well as the intervention method and intervention duration. Methods 100 elderly people in Tangshan communities with memory impairment, with score less than 22 by Rivermead Behavioural Memory Test Second Edition( RBMT Ⅱ) ,were randomly selected and divided into the intervention group(n=50) and control group( n =50). The intervention group were given personalized memory training while the control group just went its normal course. Each group was evaluated with score by RBMT Ⅱ after 3 and 6 months respectively. All the data were made analysis of variance and t test using SPSS 13.0 software. Results After 6 months of intervention, the evaluation scores in the following aspects of the standard score, immediate story recalling, immediate route recalling, letter recalling,orientation, date and appointments recalling, delayed story recalling, name recalling and the hidden recalling were significantly higher than those of control group(P＜ 0. 01 or P＜ 0.05 ). The scores in the standard score,immediate story recalling, imformation recalling, appointments recalling, delayed story recalling, name recalling after 6 months of intervention were significantly higher than those before intervention(P＜ 0.01 or P＜ 0.05). The RBMT Ⅱ score increased significantly from (17.10±2.38 ) before the intervention to ( 19.90 ±2.17) after 3 months of intervention and to( 21.63 ± 1.45 ) after 6 months (P＜0.01). Conclusion Memory intervention is an effective method worthy to be widely spread in the communities in improving the memory of elderly people with dysmnesia.
ABSTRACT
Objective To investigate the clinical features and treatment of Kaposi's varicelliform eruption. Methods Clinical data on 24 cases of Kaposi's varicelliform eruption were retrospectively analyzed.Results All the 24 patients were accompanied by different underlying skin diseases, including eczema in 17 cases and atopic dermatitis in 7 cases. PCR of vesicle fluid was positive for herpes simplex virus type 1 (HSV 1 ) in 16 (66.67%) patients, and culture of vesicle fluid or lesional exudates grew Staphylococcus aureus in 12 (50%) patients. Conclusion Infants with atopic dermatitis or eczema are rather susceptible to Kaposi's varicelliform eruption, which may be partly caused by herpes simplex virus infection.
ABSTRACT
A 54-year-old woman presented with a five-year history of malaise with weight loss and arthralgia of both knee joints. Six months prior to the presentation, an indurated nodule developed at the site of an old scar on the temporal side of left eyebrow. Subsequently, erythema and nodules spread over the trunk and extremities, especially at the sites of old scars on the hands. Physical examination showed bilateral axillary lymphadenectasis, a plaque at the site of an old scar on the temporal side of left eyebrow, a subcutaneous mass at the extensor aspect of the right upper arm, multiple dark-erythematous nodules at the site of scars on the left hand and both soles, few small erythematous papules scattered on the left forearm and trunk. The serum angiotensin converting enzyme concentration was high (82 kU/L). Computer tomography of thorax showed multiple obscure tubercles in both lungs and swollen lymph nodes in mediastina and axillary fossa, but no hilum pulmonis lymphadenectasis was observed. Histopathology revealed non-caseating granulomas with multinucleated giant cells. Neither acid-fast bacilli nor PAS staining was positive. A diagnosis of scar sarcoidosis was established. The lesions obviously improved after one-month treatment with oral methylprednisolone. This case represents a rare subtype of sarcoidosis that arose in old sears and clinically manifests as scar, nodules,plaques, subcutaneous masses and papules. The reactivation of old scars, which manifests as erythematous swelling and nodules, may highly suggest the diagnosis of sarcoidosis.
