Malignant tumors have surpassed stroke and coronary heart disease to become the main cause of death before the age of 70 in the world. The incidence of malignant tumors is increasing year by year， which seriously affects the living standards and social and economic development of Chinese people. Surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy are the main means of Western medicine to intervene in tumors， which are of great significance for prolonging the survival time of patients. However， there are many disadvantages such as adverse reactions and drug resistance. Traditional Chinese medicine has become a research hotspot in recent years because of its definite curative effect and wide application in tumor treatment. Xiao Chaihutang is derived from the Treatise on Febrile and Miscellaneous Diseases. It is composed of Bupleuri Radix， Scutellariae Radix， Ginseng Radix， Pinelliae Rhizoma， Glycyrrhizae Preparata Radix， Ginger， and Jujube. It has the effects of reconciling Shaoyang， reconciling cold and heat Yin and Yang， soothing the liver， and relieving depression. This prescription and the prescriptions based on it are widely used in various stages of tumors. This study summarized the Chinese and foreign research of Xiao Chaihutang in the field of tumors in the past 10 years and explored the role and mechanism of Xiao Chaihutang in blocking precancerous lesions， controlling the development of malignant tumors， reducing the occurrence of adverse reactions after intervention， and alleviating common complications， with a view to expanding the clinical medication ideas.

Baylisascaris schroederi,a roundworm(ascaridoid)parasite specific to the bamboo-feeding giant panda(Ailuropoda melanoleuca),represents a leading cause of mortality in wild giant panda populations.Here,we present a 293-megabase chromosome-level genome assembly of B.schroederi to infer its biology,including host adaptations.Comparative genomics revealed an evolutionary trajectory accompanied by host-shift events in ascaridoid parasite lineages after host separations,suggesting their potential for transmission and rapid adaptation to new hosts.Genomic and anatomical lines of evidence,including expansion and positive selection of genes related to the cuticle and basal metabolisms,indicate that B.schroederi undergoes specific adaptations to survive in the sharp-edged bamboo-enriched gut of giant pandas by structurally increasing its cuticle thickness and efficiently utilizing host nutrients through gut parasitism.Additionally,we characterized the secretome of B.schroederi and predicted potential drug and vaccine targets for new control strategies.Overall,this genome resource provides new insights into the host adaptation of B.schroederi to the giant panda as well as the host-shift events in ascaridoid parasite lineages.Our findings on the unique biology of B.schroederi will also aid in the development of prevention and treatment measures to protect giant panda populations from roundworm parasitism.

Esophagectomy and lymph node dissection are the cornerstones for the treatment of esophageal cancer. Upper mediastinal lymph node dissection is of great value for accurate staging and improving the prognosis of patients. Lymph node dissection along the left recurrent laryngeal nerve is the most challenging procedures in esophageal surgery, and there has been no relevant consensus on the scope and boundary of lymph node dissection. In recent years, with the application of endoscopic technology, especially robotic surgery system in esophagectomy, and the introduction of the concept of superior mediastinal microdissection, the authors have proposed the border of lymph node dissection along the left recurrent laryngeal nerve, so as to achieve precise, radical and standardized dissection. Combined with their own experiences, the authors elaborate on the anatomic boundary, extent and technique of lymph node dissection along the left recurrent laryngeal nerve.

Objective:To compare the clinical efficacy between puncture assisted by a "TINAVI" orthopaedic robot versus freehand puncture in vertebroplaty for osteoporotic vertebral compression fracture(OVCF) of the upper thoracic vertebra.Methods:A retrospective study was conducted of the 19 patients (20 vertebral bodies) with OVCF of the upper thoracic vertebra who had been treated at Department of Spine Surgery, Honghui Hospital from January 2018 to March 2019 by robotic vertebroplasty (robot group) and of another 21 counterpart patients (21 vertebral bodies) who had been treated by conventional vertebroplasty from January 2016 to December 2017 (freehand group). Puncture was conducted by a "TINAVI" orthopaedic robot in the robotic vertebroplasty but freehand in the conventional vertebroplasty. The robot group had 5 males and 14 females, aged from 62 to 88 years; the freehand group had 6 males and 15 females, aged from 64 to 83 years. The 2 groups were compared in terms of operation time, bone cement volume, postoperative complications (cement leakage, infection and embolism), visual analogue scale (VAS), Oswestry disability index (ODI), anterior height (AH) and kyphosis angulation (KA) of the injured vertebra at day 1 and last follow-up after surgery.Results:The 2 groups were comparable because there were no significant differences between them in the preoperative general data ( P>0.05). Vertebroplasty via unilateral puncture approach was completed uneventfully in the 19 patients (20 vertebral bodies) in the robot group and in the 21 patients (21 vertebral bodies) in the freehand group. The 40 patients were followed up for 6 to 12 months (mean, 8.3 month). The operation time [(37.9±8.2) min], bone cement volume [(2.3±0.9) mL] and rate of cement leakage (10.0%, 2/20) in the robot group were all significantly less or lower than those in the freehand group [(46.2±9.4) min, (4.2±1.3) mL and 42.9% (9/21)] ( P<0.05). No infection or embolism was observed in either group. There were no significant differences between the 2 groups in VAS, ODI, AH or KA of the injured vertebra at day 1 or last follow-up after surgery ( P>0.05). Conclusion:In vertebroplaty for OVCF of the upper thoracic vertebra, compared with conventional freehand puncture, puncture assisted by a "TINAVI" orthopaedic robot can lead to satisfactory clinical efficacy because it reduces operation time, volume of bone cement injection, and thus incidence of bone cement leakage.

The objective of this study was to elucidate the effect of chronic stress (CS) on dopamine (DA) level and synaptic efficiency in the hippocampal dentate gyrus (DG) during spatial learning and memory. Sprague Dawley (SD) male rats were randomly divided into control group and CS group (n = 10). CS group was treated with chronic mild unpredictable stress, and control group did not receive any treatments. The levels of epinephrine and corticosterone (CORT) in serum were measured by using enzyme-linked immunosorbent assay (ELISA); the spatial learning and memory abilities of rats were measured by Morris water maze (MWM) test. Meanwhile, the amplitude of field excitatory postsynaptic potential (fEPSP) and concentration of DA in the DG region were determined by in vivo electrophysiology, microdialysis and HPLC techniques during MWM test in rats. After that, the DA D1 receptor (D1R) and its key downstream members in DG were examined by immunohistochemistry or Western blot assay. The results showed that the levels of epinephrine and CORT in the serum of the rats in CS group were significantly increased compared with those in the control group (P < 0.05). In CS group rats, the escape latency was significantly prolonged and the number of platform crossing was markedly decreased during MWM test, compared with those in control group (P < 0.05). Furthermore, the amplitude of fEPSP in the DG was not changed during MWM test in CS rats, while it was significantly increased on the 3rd day of MWM test in control group (P < 0.05). Compared with baseline or control group, CS group showed significantly increased DA level from the 1st to 3rd days of MWM test in the DG (P < 0.05). In addition, the protein expression of D1R was markedly up-regulated in the DG in CS group, while the protein expression levels of p-PKA, p-CREB and BDNF were significantly reduced, compared with those in control group. These results suggest that CS may impair spatial learning and memory abilities in rats through the enhancement of the DA levels in the hippocampal DG.

Objective:To study the strategy of endovascular treatment for patients with the risks of internal carotid artery (ICA) rupture and bleeding during the treatment of nasopharyngeal carcinoma (NPC) based on American Society of Intervention and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) grade of collateral circulation.Methods:A total of 56 patients (45 males and 11 females, aged from 28 to 76 years old) diagnosed with nasopharyngeal carcinoma and admitted to the Department of Neurosurgery, the Third Affiliated Hospital of Southern Medical University from July 2018 to January 2020 were retrospectively analyzed. There were 15 cases of ASITN/SIR grade 4, 24 cases of ASITN/SIR grade 3, 5 cases of ASITN/SIR grade 2, 5 cases of ASITN/SIR grade 1, and 7 cases of ASITN/SIR grade 0. The events of stroke and death were analyzed statistically.Results:ALL patients with ASITN/SIR grade 4 or 3 and some of patients with ASITN/SIR grades 2-0 passed balloon occlusion test and electrophysiological monitoring. ICA pseudoaneurysm was found in 35 patients, and one-stage ICA embolization was performed in 29 patients after evaluation. Among them, 8 cases of ASITN/SIR grade 4 and 10 cases of ASITN/SIR grade 3 with obvious posterior circulation compensation obtained successful one-stage ICA embolization without cerebral ischemia; cerebral ischemic events occurred in 5 (55.6%) of 9 patients with ASITN/SIR grade 3 and in 1(50.0%) of 2 patients with ASITN/SIR grade 2. The total incidence of ischemic events was 20.7% (6/29) and 1 case was disabled (1/29, 3.4%). Among patients with ASITN/SIR 3, there were statistically significant differences in stroke event rate between patients with obvious posterior circulation compensation and patients with slight or without posterior circulation compensation (0/10 vs. 5/9, χ 2=4.95, P=0.026). Follow-up time was 10.1±7.8 months, and 46 patients were survival (46/56, 82.1%) and 10 patients died (10/56, 17.9%) with a mean survival time of 2.6±1.4 months. Conclusions:For NPC patients with ICA invasion, ASITN/SIR based on DSA can simplify the assessment process of cerebral blood flow compensation. ICA can be embolized directly in patients with ASITN/SIR 4 or 3 with obvious posterior communicating compensation.

Objective To evaluate the precise percutaneous sacroplasty (PSP) assisted by a Renaissance robot for sacral insufficiency fractures (SIF).Methods The clinical data of 12 SIF patients were retrospectively analyzed who had been treated from March 2016 to March 2018 at Department of Spinal Surgery,Honghui Hospital.They were 5 males and 7 females,aged from 55 to 76 years (average,67.5 years).They all received PSP assisted by a Renaissance robot.Their operation time,hospital stay and intraoperative radiation were recorded.The clinical efficacy was evaluated by comparing their visual analogue scale (VAS) and Oswestry disability index (ODI) before surgery,1 day,3 and 12 months after surgery.Results All the 12 patients underwent surgery successfully with no complications like cement leakage.Their operation time ranged from 32 to 47 minutes (mean,36.8 minutes),their hospital stay from 12 to 25 hours (mean 17.5 hours) and their intraoperative exposure to radiation from 0.87 to 1.53 mSv (mean,1.27 mSv).All the patients were followed up for 12 to 18 months (mean,15.8 months).Their VAS (1.7 ± 0.7) and ODI (22.8 ± 4.1) one day after surgery were significantly decreased than the preoperative values (7.6 ±0.9 and 43.7 ±4.6) (P ＜ 0.05).At 3 and 12 months after surgery,their VAS scores were 2.0 ± 0.8 and 2.4 ±0.8 and their ODI scores 21.5 ±4.3 and 23.0 ±4.6,respectively,showing no significant differences from the values at 1 day after surgery (P ＞ 0.05).Conclusion The PSP assisted by a Renaissance robot is safe and leads to satisfactory clinical efficacy for SIF as bone cement can be accurately injected into the target area of the fracture.
