Objective To observe the curative effect of condyloma acuminatum patients treated with differences of bacilli phlei injection after fulfufized and the effect of immunity function. Methods We compared curative effect and peripheral blood T lymphocyte subpopulation in the treatment group( 55 cases, 8 weeks, prior and posttreatment with differences of bacilli phlei only) and the control group (50 cases, 8 weeks, prior and post-treatment with recombinant human interferon α-2b only). Results Compared with the control group (24.0 %/41.7 % ), the treatment group(47.3 %/11.5 % ) had advantage in the terms of cure rate and relapse rate( P<0.05 ). CD+3, CD+4 ,CD4+/CD+8 increased and CD+8 decreased in two groups after treatment. CD+3 , CD+4, CD+4/CDs+ were significantly increased in treatment group compared with the control group after treatment(P<0.05), but CD+8 had no obvious difference in two groups(P>0.05). Conclusion Differences of bacilli phlei injection can prevent relapse of condyloma acuminatum and increase immunity function of patients.

BACKGROUND: Oxfordshire Community Stroke Project(OCSP) is a new type of clinical classification for subdividing cerebral infarction(CI) conducted on the basis of a large-scale of investigation of stroke in the population of Oxfordshire Community, England in 1991. This kind of classification completely bases on the clinical manifestations without the help of diagnostic instruments, which can predict site and size of the lesion and the involved vessels.OBJECTIVE: To acknowledge the clinical classification of CI patients with Bamford's OCSP and its significance in predicting their long-term functional prognosis.DESIGN: Clinical observation, comparison and verified study based on patients.SETTING: Neurological department in a university hospital.PARTICIPANTS: Between January 1st and December 31st 2001, totally 126 patients with cerebrovascular disease were hospitalized in the Neurological Department of First Affiliated Hospital of Xi' an Jiaotong University,including 82 males and 44 females.METHODS: Totally 126 in-patients with CI were subdivided with Bamford's OCSP classification, and their disablity was assessed with Barthel index (BI)and modified Rankin Scale(mRS) when they were discharged and 3 months and 6 months later.MAIN OUTCOME MEASURES: Classification of patients with CI and their scores of BI and mRS when they were discharged and 3 months and 6months later.RESULTS: Of the 126 patients, 8(6. 3% ) patients were confirmed of total anterior circulation infarction (TACI), 29 (23. 0% ) of part anterior circulation infarction(PACI), 78(61.9% ) of lacunar infarction(LACI), 11(8.7%) of posterior circulation infarction(POCI) . They were followed-up for 6 months, and meanwhile 12 patients died. Of the other 114 cases the prognosis of TACI was the worst, while the prognosis of POCI and LACI was relatively better than that of PACI.CONCLUSION: CI is predominated by LACI. OCSP is effective for predicting long-term functional prognosis of patients with CI. But it is necessary to make multi-center prospective study on a much larger scale of samples of disease.

Objective:To compare the efficacy of 3D-printed guide plate assisted versus freehand placement of cannulated screws for the treatment of Sanders type II and III calcaneal fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 29 patients with Sanders type II and III calcaneal fractures admitted to Chonggang General Hospital from June 2020 to October 2022. Among them, there were 18 males and 11 females, with an age range of 22-69 years [(40.1±11.5)years]. Nineteen patients were treated with individualized 3D-printed guide plate assisted placement of cannulated screws (3D-printed group) and 10 were treated with freehand placement of cannulated screws (freehand group). The surgical time, fluoroscopy times, postoperative 6-month calcaneal morphology (length, width, height, B?hler angle and Gissane angle), and American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Maryland functional score assessed at 3, 6 months after operation and at the final follow-up were compared between the two groups. The incision healing and complications were observed.Results:The patients were followed up for 6-24 months [(11.3±2.5)months]. The surgical time and fluoroscopy times in the 3D-printed group were (53.4±9.1)minutes and (7.3±1.1)times, respectively, which were shorter than (90.2±16.0)minutes and (16.0±3.2)times in the freehand group (all P<0.01). At 6 months after operation, there was no significant difference in calcaneal length between the two groups ( P>0.05); the calcaneal width, height, B?hler angle and Gissane angle in the 3D-printed group [(34.0±1.8)mm, (47.2±1.6)mm, (27.8±1.0)°, (129.2±2.8)°] were superior than those in the freehand group [(37.5±2.0)mm, (43.0±2.7)mm, (25.8±1.5)°, (125.9±2.5)°] (all P<0.01). At 3, 6 months after operation and at the final follow-up, the values of AOFAS ankle-hindfoot score in the 3D-printed group [(72.2±2.3)points, (79.7±2.3)points, (86.5±4.4)points] were higher than those in the freehand group [(64.2±6.9)points, (73.4±4.2)points, (81.8±3.1)points] (all P<0.05); the values of Maryland score in the 3D-printed group [(71.4±7.7)points, (84.7±2.6)points, (91.5±2.5)points] were higher than those in the freehand group [(65.2±5.6)points, (79.1±3.8)points, (87.1±2.9)points] (all P<0.05). All surgical incisions were healed in stage I. In the 3D-printed group, there were no complications regarding infection, iatrogenic vascular or nerve injury, or fixation failure after surgery. In the freehand group, one patient with lateral sural cutaneous nerve injury was resolved spontaneously without specific treatment. Conclusion:Compared with freehand placement of cannulated screws, 3D-printed guide plate assisted placement of percutaneous placement has the advantages of shorter surgical time, fewer fluoroscopy times, lower reduction loss, better ankle joint function recovery, and less complications in treating Sanders type II and III calcaneal fractures.

Objective:To investigate the clinical efficacy of proximal gastrectomy and total gastrectomy in the treatment of Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG).Methods:The retrospective cohort study was conducted. The clinicopathological data of 170 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to Guangdong Provincial People′s Hospital from January 2010 to December 2018 were collected. There were 125 males and 45 females, aged from 30 to 85 years, with a median age of 64 years. Of the 170 patients, 82 cases undergoing proximal gastrectomy were allocated into the proximal gastrectomy group and 88 cases undergoing total gastrectomy were allocated into the total gastrectomy group. Observation indica-tors: (1) surgical and postoperative situations; (2) follow-up and survival; (3) analysis of prognostic factors. Follow-up was conducted using telephone interview and outpatient examination to detect survival of patients up to December 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measure-ment data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Kaplan-Meier method was used to draw survival curves, and Log-Rank test was used for survival analysis. COX proportional hazard model was used for univariate and multivariate analyses. Variables with P<0.1 in univariate analysis were included for multivariate analysis. Results:(1) Surgical and postoperative situations. Cases with surgical approach as transthoracic or thoraco-abdominal approach, transabdominal approach, the operation time, cases with volume of intra-operative blood loss ≤100 mL or >100 mL, cases with length of proximal margin ≤1.5 cm or >1.5 cm, cases with radical surgery outcome as R 0, R 1, R 2, the number of lymph nodes harvest, cases with anastomotic leakage, cases with anastomotic stricture, cases with incision infection, cases with pleural infection or effusion, cases with abdominal infection or ascites were 61, 21, (211±18)minutes, 46, 36, 44, 38, 73, 6, 3, 15(9,22), 5, 2, 2, 4, 2 in the proximal gastrectomy group, respec-tively. The above indicators were 12, 76, (263±15)minutes, 27, 61, 45, 43, 82, 4, 2, 23(18,32), 4, 1, 3, 1, 4 in the total gastrectomy group, respectively. There were significant differences in the surgical approach, operation time, volume of intraoperative blood loss and the number of lymph nodes harvest between the two groups ( χ2=63.94, t=-25.50, χ2=11.19, Z=-5.62, P<0.05). There was no significant difference in the length of proximal margin or radical surgery outcome between the two groups ( χ2=0.11, Z=-0.95, P>0.05) and there was no significant difference in the anastomotic leakage, anastomotic stricture, incision infection, pleural infection or effusion, abdominal infection or ascites between the two groups ( P>0.05). (2) Follow-up and survival. All the 170 patients were followed up for 89(64,106)months. Of the 170 patients, the 5-year overall survival rates were 43.8% and 35.5% of the Siewert type Ⅱ and Ⅲ AEG patients, respectively, showing no significant difference between them ( χ2=0.87, P>0.05). Of the patients with Siewert type Ⅱ AEG, the 5-year overall survival rates were 41.7% and 54.3% in the patients with proximal gastrectomy and the total gastrectomy, respectively, showing no significant difference between them ( χ2=1.05, P>0.05). Of the patients with Siewert type Ⅲ AEG, the 5-year overall survival rates were 31.3% and 37.5% in the patients with proximal gastrectomy and the total gastrectomy, respectively, showing no significant difference between them ( χ2=0.33, P>0.05). The 5-year overall survival rates were 39.0% and 44.2% in the proximal gastrectomy group and the total gastrectomy group, respectively, showing no significant difference between the two groups ( χ2=0.63, P>0.05). Of the patients in TNM stage Ⅰ, stage Ⅱ, stage Ⅲ, the 5-year overall survival rates were 65.3%, 36.3%, 27.1% in the proximal gastrectomy group, versus 83.3%, 48.0%, 39.7% in the total gastrectomy group, showing no signifi-cant difference between the two groups ( χ2=0.02, 1.50, 1.21, P>0.05). (3) Analysis of prognostic factors. Results of univariate analysis showed that pathological N staging, degree of tumor differen-tiation and radical surgery outcome were related factors influencing prognosis of AEG patients ( hazard ratio=1.71, 1.70, 2.85, 95% confidence interval as 1.16-2.60, 1.15-2.50, 1.58-5.14, P<0.05). Results of multivariate analysis showed that pathological N staging and radical surgery outcome were independent factors influencing prognosis of AEG patients ( hazard ratio=1.55, 2.18, 95% confidence interval as 1.05-2.31, 1.18-4.02, P<0.05). Conclusions:There is no significant difference in the prognosis of Siewert type Ⅱ and Ⅲ AEG patients undergoing proximal gastrectomy or total gastrectomy. Proximal gastrectomy can be used for the treatment of advanced Siewert type Ⅱ and Ⅲ AEG.
