OBJECTIVE: To investigate the effects of two types of temperature rinses on body temperature, inflammatory cytokine levels, and bleeding volume in percutaneous endoscopic lumbar discectomy. METHODS: Eighty patients underwent percutaneous endoscopic lumbar discectomy from January 2018 to December 2020 were selected and divided into experimental group (40 cases) and control group(40 cases). In experimental group, there were 19 males and 21 females, aged (38.8±9.8) years old;7patients on L_4,5 and 33 patients on L₅S₁;Body msss index(BMI) was (27.8±7.2) kg·m^-2. In contral group, there were 18 males and 22 females, aged (41.5±10.9) years old, 5 patients on L_4,5 and 35 patients on L₅S₁;BMI was (26.4±6.2) kg·m^-2. The patients in the control group were received normal saline rinse at room temperature, and the patients in the experimental group were received normal saline rinse heated to 37 ℃. Body temperature, chills, nausea, vomiting, and other adverse reactions were recorded. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10) in two groups were recorded before and 2 hours after operation. Visual analogue scale (VAS) was used to evaluate the degree of lumbar pain in two groups before and 2 hours after surgery. Fibrinolytic-coagulation indexes with preoperative and 2 hours after surgery, including the D-dimer (DD), fibrinogen degradation products (FDP), activated partial thrombin time (APTT) and prothrombin time (PT) were recorder. Operation time and blood loss in two groups were recorded. RESULTS: The body temperature of both groups showed a downward trend, while the body temperature of the control group was lower than that of the experimental group. The levels of TNF-α, IL-6 and IL-10 in two groups were increased 2 hours after surgery compared with those before surgery(P<0.05), while the levels in experimental group were lower than those in control group(P<0.05). Postoperative VAS in experimental group 2.19±1.13 was significantly lower than that in the control group 3.38±1.35(P<0.05). The levels of DD and FDP at 2 hours after surgery in both groups were higher than those before surgery (P<0.05), while the levels of DD and FDP in the experimental group were higher than those in the control group (P<0.05). There was no significant difference in APTT and PT levels between two groups after operation (P>0.05). The blood loss in the experimental group of (45.2±14.1) ml was lower than that in the control group of (59.52±15.6) ml. The operation time of experimental group (46.7±13.8) min was less than that of control group (58.3±15.2) min(P<0.05). CONCLUSION Body temperature rinse can reduce the incidence of adverse reactions, alleviate local inflammatory reactions, reduce intraoperative blood loss and shorten the operation time.

AIM: To explore the influence of processing with fresh-scorpion on element contents in crude scorpion in order to elucidate the processing method. METHODS: Macro-elements Ca,Mg and trace-elements Fe,Cu,Zn and Pb in crude scorpion were determined with emission spectrometric method. RESULTS: Contents of Ca,Mg in live-scorpion group were obviously lower than that in commercial-scorpion(P0.05). CONCLUSION: Processing with live-scorpion has obviously advantage over one with commercial scorpion on element contents.

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Rare diseases have been a major challenge for clinical medicine and public health challenge in China. One of the effective measures is to conduct proactive research on rare diseases to deal with the disease burden of the diseases. However, low prevalence, disperse distribution of patients, lack of knowledge about the disease course, and phenotype heterogeneity hamper the development of research for rare diseases. Recently, it has been found that patients registry is effective in understanding the course of the disease and accu- mulating the cases and data of clinical research or clinical trial design. At present, most of developed countries or regions in the world have promoted clinical research and clinical trials of new medications on rare diseases by using the registration of rare disease. In 2016, Peking Union Medical College Hospital established China's first registry system at the national level-National Rare Disease Registry System of China(NRDRS). NRDRS has accumulated 68 137 cases data registered by the researchers from China's 101 collaborating hospitals in 29 provinces/municipalities/autonomous regions, covering 171 different, and forming 188 cohorts. To date, NRDRS complete the initial stage of resources buildup.Nex stage will be focused on clinical research and clinical trials related to rare diseases based on NRDRS. This article is on the process of building NRDRS, the potential support for conducting clinical research and clinical trials related to rare diseases, and the challenges will be faced.
