Objective To explore the significance of established Tp0259-PCR in diagnosing primary syphilis.To provide basis for establishing new PCR diagnosis method of Treponema pallidum.Methods Specific primers were designed by the gene sequences of Tp0259 which was obtained from Genbank.Tp0259-PCR was established under the optimization reaction condition.Using the new construction of amplification method to detect the common pathogenic microorganism in urinary and reproductive tract infec-tion.42 clinical secretion specimens suspected primary syphilis were tested by Tp0259-PCR.Serum specimens from the same pa-tients were tested by TPPA.Results Only specific amplicons could be found in amplifying the Treponema pallidum by Tp0259-PCR.The detection rate was 73.8% using Tp0259-PCR which was apparently higher than 57.1% using TPPA(P <0.05 ).The specificity of the established method was 100% comparing with TPPA.Conclusion The established method of Tp0259-PCR has high sensibility and specificity.This method might be better than serological method in diagnosis of primary syphilis.but its clinical diagnosis value need to be repeatedly verified by more clinical specimens.

This study was aimed to investigate the efficacy ofTong-Bu San-Sheng(TBSS) Decoction to reduce the toxicity and side effects of chemotherapy, as well as prolong progression-free survival (PFS) for advanced lung squamous carcinoma patients who received chemotherapy. A total of 83 lung squamous carcinoma cases were divided into two groups by patients’ wishes. The control group contained 41 cases were treated by the chemotherapy of gemcitabine plus cisplatin (GP). The trial group contained 42 cases were treated by chemotherapy plus Chinese herbal medicine TBSS decoction. The toxicity and side effects of chemotherapy, as well as short-term outcome were evaluated. PFS of patient was recorded. The results showed that there were no differences on granulocytopenia (P = 0.115) or short-term outcome (P = 0.081) for patients of both groups after chemotherapy. The percentages of nausea, vomiting and thrombocytopenia in the trial group were lower than that in the control group (P = 0.037,P = 0.040). The PFS of patients in the trail group were prolonged compared to patients in the control group (4.31 ± 0.24 VS 3.78 ± 0.16 month;P = 0.043). It was concluded that Chinese herbal medicine TBSS decoction cannot reduce granulocytopenia caused by chemotherapy, or improve the tumor response rate (RR) of short-term outcome. However, it can prolong PFS, relieve nausea, vomiting and thrombocytopenia during chemotherapy.

Objective:To explore the efficacy of total sternotomy or partial sternotomy for the treatment of isolated plasmacytoma of the sternum, and the feasibility of the chest wall reconstruction using 3D printed polyether ether ketone(PEEK) implants.Methods:In this study, a total of 6 patients with isolated plasmacytoma of sternum was enrolled, including 5 males and 1 female, aged (57.7±9.4) years old (42-71 years old). All patients received total sternotomy or partial sternotomy, and the chest wall was reconstructed using 3D-printed PEEK implant. The perioperative data and demographic characteristics of the patients were collected for statistical analysis.Results:All patients in this study had isolated plasmacytoma of sternum. Chest wall defects with mean area of (102.7±18.8)cm 2 were anatomically repaired using 3D-printed PEEK implants. No postoperative complications such as abnormal respiration was found. All 6 patients were discharged from hospital successfully, and no complications during the perioperative period were found. During the average follow-up period of(31.2±15.4)months, no implant fracture, displacement, rejection and other phenomena occurred, and no recurrence, metastasis or death occurred in postoperative patients. Conclusion:Total or partial sternotomy was an effective treatment for isolated sternum plasmocytoma . The chest wall reconstruction using 3D-printed PEEK implant was a reliable clinical treatment method.

Objective:To investigate the safety and feasibility of Ivor-Lewis procedure under uniportal video-assisted thoracoscopy(VATS) for esophageal cancer and Siewert type I esophago-gastric junction carcinoma.Methods:The patients with middle-lower segment esophageal cancer or Siewert type I esophago-gastric junction carcinoma received minimally invasive esophagectomy between October 2020 and June 2021, and the clinical data was collected and analyzed.Results:26 patients received Ivor-Lewis procedure underwent uniportal VATS, while 45 patients underwent McKeown surgery under multiport VATS. The average operation time of patients in the two groups were(265±110)min and (235±94)min, and the average intraoperative blood loss were(80±57)ml and(105±60)ml. The mean number of lymph nodes removed in the surgery were (19.3±2.9) and 18.6±2.7 respectively in two groups, and the mean length of hospital stay was(7.5±3.5)days and(8.3±2.7)days. The incidence of perioperative complications were not significantly different in two groups. The VAS score of patients received Ivor-Lewis procedure underwent uniportal VATS was lower than that of patients received McKeown surgery in ostoperative day 1, day 3, day 7 and 1 month. The difference was statistically significant in two groups( P<0.05). Conclusion:The Ivor-Lewis procedure under uniportal VATS for esophageal cancer and Siewert type I esophago-gastric junction carcinoma has the advantage of less postoperative pain, and the procedure is feasible in clinical practice.

Objective In this study, three-dimensional printed (3DP) titanium implants were used for skeletal reconstructions after wide excision of chest wall. 3DP titanium implants were expected to provide a valid option with perfect anatomic fitting and personalized design in chest wall reconstruction. Methods There were 13 patients [mean age of 46 (24-78) years with 9 males and 4 females] who underwent adequate radical wide excision for tumors and chest wall reconstruction using 3DP titanium implants. Surgical data including patient demographic characteristics, perioperative clinical data and data from 1-year follow-up were collected and analyzed. Results Six patients of rib tumors, six patients of sternal tumors and one patient of sternal pyogenic osteomyelitis were finally selected for the study. The chest wall defect area was 221.0±206.0 cm2. All patients were able to maintain the integrity of the chest wall after surgery, and no abnormal breathing was found, achieving personalized and anatomical repair. Thirteen patients were successfully discharged from the hospital. Two patients developed pneumonia in the perioperative period. During the follow-up period in the first year after surgery, no implant related adverse reaction was observed, including implant rupture, implant shift, rejection reaction and allergies. One patient had wound ulcer after chemotherapy. Three patients had tumor recurrence, with the recurrence rate of 25.0%. Two patients died of tumor recurrence, with a mortality rate of 16.7%. Conclusion 3DP titanium implant is a safe and effective material for chest wall reconstruction.

Objective To explore the safety and effectiveness of a precise marking method based on body surface mesh and three-dimensional (3D) image reconstruction. Methods We retrospectively analyzed the clinical data of 22 patients in our hospital from October 2018 to October 2019. There were 13 males and 9 females aged 58.5 (37-72) years. All patients underwent a precise marking of pulmonary nodules based on body surface mesh and 3D image reconstruction. Then, video-assisted thoracoscopic surgery (VATS) was performed to resect the nodules. The clinical data, including positioning success rate and operation time were analyzed. Results A total of 22 small pulmonary nodules were removed. The average diameter of small nodules was 12±3 mm, and the average distance from the visceral pleura was 17±6 mm. The localization success rate was 86.4%. The operation time was 110±43 min, and there was no surgery-related complication. Conclusion The method of marking pulmonary nodules based on body surface mesh and 3D image reconstruction is a safe and reliable technology, which reduces the risk of hemopneumothorax caused by CT-guided lung puncture.
