ABSTRACT

@#Abstract: Objective To analyze the epidemiological characteristics of scrub typhus in 680 patients with unexplained fever in Hainan Island and provide guidance for local scrub typhus prevention and control. Methods Blood samples from patients with clinically diagnosed unexplained fever in the First Affiliated Hospital of Hainan Medical University, Second Affiliated Hospital of Hainan Medical University, Haikou Municipal People's Hospital and Central South University Xiangya Medical College Affiliated Hospital, People's Hospital of Qiongzhong Li Miao Autonomous County were collected between 2018 and 2021, then samples were tested for Orientia tsutsugamushi specific IgM, IgG antibodies and Orientia tsutsugamushi 56kD-specific antigen genes using colloidal gold immunochromatography and PCR methods. The clinical and epidemiological information of the samples were also collected. Epidemiological analysis was carried out on the obtained sample information and test results. Results A total of 680 samples from patients with clinically unknown fever were collected. The positive rates of scrub typhus IgM antibody, IgG antibody, PCR were 23.97% (163/680), 36.62% (249/680), 20.88% (142/680), respectively, and eschar or rash was observed in 12.06% (82/680) of all patients. According to the diagnostic criteria, 223 patients were finally diagnosed with scrub typhus. Among them, there were 111 males (49.78%) and 109 females (48.88%); the average age was (53.14±15.12) years old, and the 40-<60 years old was the main incidence group (98 cases, accounting for 43.95%). The ethnicity of the patient with scrub typhus was mainly Han ethnicity (136 cases, accounting for 60.99%). Farmers were the main morbidity group (93 cases, 41.70%). The patient with scrub typhus distributed throughout the island except for Sanya and Wuzhishan, with Haikou and Qiongzhong show the highest number of cases. The number of cases in autumn was the highest (114 cases, 51.12%). The clinical manifestations of infected patients were mainly non-specific symptoms and signs, 36.77% of patients developed skin-specific ulcers or eschars, which were mainly distributed in the shoulder and neck, armpits, elbow fossa, chest and abdomen, back, buttocks, groin, scrotum and other joints and skin folds of the upper and lower limbs. Conclusions Hainan Island is the foci of scrub typhus and the epidemic time has obvious seasonality. Its prevention should focus on rural areas in autumn, and its clinical features are mainly high fever and eschar or ulceration.

ABSTRACT

@#Objective To evaluate the feasibility and safety of single utility port video-assisted thoracoscopic surgery (VATS) anatomic segmentectomy for lung diseases. Methods We performed a retrospective review of 155 patients undergoing single utility port VATS anatomic segmentectomy from January 2015 to December 2016. There were 62 males and 93 females with a mean age of 53 (24–82) years. Two ports were used. The camera was through the port for observation which was about 1.5 cm in length and located at the 7th or 6th intercostal space. The instruments were through port for operation that was about 3–4 cm in length and located at the 4th or 3th intercostal space. Pulmonary segment vessel and segmental bronchi were cut and stitched by Hemolock or linear cut stapler. Different segments were separated by linear cut stapler. Perioperative data were collected and analyzed. Results One patient was performed suture under the auxiliary operating hole (three holes) because of pulmonary artery bleeding. The remaining 154 patients underwent single utility port VATS anatomic segmentectomy successfully. No conversion to open procedure or lobectomy was found and there was no perioperative mortality. The median operative time was 102 (65–150) min and the median blood loss in operation was 118 (50–300) ml. The thoracic drainage time was 3.8 (2–7) d and the median hospital stay after operation was 5.6 (3–9) d . Major morbidity occurred in 8 patients (5.2%) including hemoptysis (in 2 patients), pneumonia (in 2 patients), aerodermectasia (in 1 patient), pleural effussion (in 1 patient) and local atelectasis (in 1 patient). All of them above healed after symptomatic treatment. Patholocal examination showed there were 139 patients of primary lung carcinoma (pathologically staged as Tis-T1bN0M0), 9 patients of benign diseases and 7 patients of metastasis tumor. Conclusion Single utility port VATS anatomic segmentectomy procedure is safe and feasible. It can be utilized as an option for those with non-small cell lung cancer staged Ⅰa and those unable to tolerate pulmonary lobectomy.

ABSTRACT

@#To share the clinical experience of thoracoscopic unidirectional posterolateral basal segmentectomy via inferior pulmonary ligament. Methods    All the patients were in the healthy lateral position, with endoscopy holes in the 8th intercostal space of the middle axillary line and 2-3 cm operation holes in the 5th intercostal space of the front axillary line. Anatomical segmentectomy of the posterolateral basal vein, bronchus and artery was performed through the inferior pulmonary ligament upward in turn. The clinical data of this group were analyzed retrospectively. Results    From December 2015 to October 2018, 32 patients underwent thoracoscopic unidirectional posterolateral basal segmentectomy, including 8 males and 24 females, aged 13-71 (52.6±13.7) years. All patients successfully completed the operation, including 9 patients of left lower pulmonary posterolateral basal segmentectomy, 23 patients of right lower pulmonary posterolateral basal segmentectomy. The operation time was 80-295 (133.4 ±40.5) minutes, intraoperative bleeding volume was 20-300 (52.6±33.8) mL, drainage time was 2-14 (4.2±2.3) days, hospitalization time was 4-15 (6.9 ±2.4) days. No death occurred during hospitalization. Postoperative complications included atelectasis in 1 patient and persistent pulmonary leakage over 3 days (4 or 6 days respectively) in 2 patients , chylothorax in 1 patient. All of them recovered smoothly after non-operative treatments. Postoperative pathology showed that 29 patients of primary adenocarcinoma or atypical adenomatoid hyperplasia, including 5 patients of adenocarcinoma in situ, 9 patients of micro-invasive adenocarcinoma, 12 patients of invasive adenocarcinoma, 3 patients of atypical adenomatoid hyperplasia. One patient was of intestinal metastatic adenocarcinoma, 1 patient of inflammatory lesion and 1 patient of bronchiectasis. 3-21(9.6±4.6) lymph nodes were resected in the patients with primary pulmonary malignant tumors. And no metastasis was found. Conclusion    The operation of thoracoscopic unidirectional posterolateral basal segmentectomy via inferior pulmonary ligament is easy. There is no need to open intersegmental tissue. It can protect lung tissue better. The operative method is worthy of clinical promotion.

Methods    The clinical data of 21 patients with giant mediastinal mass who underwent surgical treatment in Xinhua Hospital of Shanghai from January 2007 to July 2016 were retrospectively reviewed. There were 14 males and 7 females, with a mean age of 34.62 ± 22.95 years (range: 11 months to 79 years), and mean weight of 58.07±22.24 kg (range: 10.8 to 90.5 kg). Their clinical manifestation, anesthesia methods, surgical treatment and the prognosis were analyzed. Results    The tumor volume ranged from 8 cm×6 cm×6 cm to 25 cm×25 cm×8 cm. For surgical approach, 12 patients received median sternotomy, 5 anterior lateral incision, 1 posterior lateral incision, 2 "L"-shape sternotomy, 1 cervical and thoracic "]"-shape incision. All patients were given mass radical resection, except one patient with two-stage resection. Twelve patients needed other tissues resection besides the single tomor resection. The operation time was 55-480 (207.86±87.67) min, blood loss volume 700 (10-4 000) ml, intraoperative blood transfusion 800 (0-4 100) ml, postoperative mechanical ventilation time 4.75 (0-87) h, postoperative drainage time 3-12 (7.43±2.66) d, the total drainage volume 295-4 940 (1 584.76±1 173.98) ml, average daily drainage volume 62-494 (204.90±105.76) ml, and postoperative hospital stay 7-47 (11.86±8.51) d. The postoperative complications included pericardial effusion in 1 patient, Horner   syndrome in 1, left recurrent laryngeal nerve injury with the left phrenic nerve injury in 1, right phrenic nerve injury in 1 and delayed wound healing in 1. The remaining patients recovered well. All patients were followed up for 1 month to 9 years. Till September 1, 2016, 5 patients died and 2 suffered recurrent tumor. Conclusion    It is safe to perform surgical treatment after comprehensive evaluation of patients with giant mediastinal mass, perioperative mortality is low, and prognosis in patients with benign tumor is good.

ABSTRACT

Protein tyrosine phosphatases [PTPs] are enzymes that catalyze protein tyrosine dephosphorylation of which Src homology phosphatase-1 [SHP-1] is one of the best-validated, a widely distributed intracellular tyrosine phosphatase that contains two SH2 domains. Down regulation of SHP-1 tyrosine phosphatases was significantly increased sensitivity to insulin in insulin signaling pathway. Through in vitro enzymatic reaction kinetics experiment, we found that the extract of Perilla stem was a potential inhibitor to [delta]SHP-1, the catalytic domain of SHP-1 protein tyrosine phosphatase, and its IC[50] was 4ug/ml, and was more sensitive towards SHP-1than other PTPs, which indicated that SHP-1 might be a target of the extract of Perilla stem. It can strengthened the level of tyrosine phosphorylation of insulin receptor [IR] and extracellular signal-regulated protein kinase [ERK] in HepG2 cells, and then activated the insulin signaling pathway through inhibiting the protein phosphorylation of SHP-1. These results demonstrated that the extract of Perilla stem could play an important role for diabetes treatment through inhibiting the level of SHP-1 in insulin signaling pathway
