Effect of Wrist-Ankle Acupuncture on Postoperative Analgesia after Total Knee Arthroplasty / 中国结合医学杂志

OBJECTIVE@#To evaluate the effect of wrist-ankle acupuncture (WAA) in pain and functional recovery after total knee arthroplasty (TKA).@*METHODS@#From June to September 2020, 94 participants were included from the Second Hospital of Tangshan and randomly assigned to the WAA group (47 cases) and the sham WAA group (47 cases) by a random number table, receiving real or sham WAA treatment, respectively. The primary outcome measure involved the visual analogue scale (VAS) scores at rest and in motion. The secondary outcomes involved the range of motion (ROM) of the knee joints, straight-leg raising time, postoperative weight-bearing time, sufentanil consumption within 48 h of patient-controlled analgesia (PCA) pump, length of hospital stay, and postoperative complications.@*RESULTS@#The VAS scores on the 3rd, 5th, and 7th postoperative days at rest and in motion was significantly lower in the WAA group than that of the sham WAA group (P<0.01). The ROM on the 1st, 2nd, and 3rd PODs was significantly higher in the WAA group than that of the sham WAA group (P<0.01). In comparison to the sham WAA group, the sufentanil consumption within 48 h of PCA pump was significantly less in the WAA group (156.3 ± 12.2 µg vs. 128.8 ± 9.8 µg, P<0.01). There was no significant difference in active straight-leg raising time, postoperative weight-bearing time, length of hospital stay, and postoperative complications between the two groups (P>0.05).@*CONCLUSIONS@#WAA could alleviate post-TKA pain, improve knee joint function, and reduce the sufentanil consumption within 48 h of PCA pump. WAA is a safe and effective treatment in the perioperative analgesic management for TKA.

A single-center, retrospective analysis of relapse and progression patterns of primary central nervous system lymphoma: can whole brain radiotherapy be replaced? / 南方医科大学学报

OBJECTIVE@#To analyze recurrence and progression patterns of primary central nervous system lymphoma (PCNSL) in patients without whole brain radiotherapy (WBRT) and assess the value of WBRT in PCNSL treatment.@*METHODS@#This retrospective single-center study included 27 patients with PCNSL, who experienced recurrence/progression after achieving complete remission (CR), partial remission, or stable disease following initial treatments with chemotherapy but without WBRT. The patients were followed up regularly after the treatment for treatment efficacy assessment. By comparing the anatomical location of the lesions on magnetic resonance images (MRI) at the initial diagnosis and at recurrence/progression, we analyzed the patterns of relapse/progression in patients with different treatment responses and different initial status of the lesions.@*RESULTS@#MRI data showed that in 16 (59.26%) of the 27 patients, recurrence/progression occurred in out-field area (outside the simulated clinical target volume [CTV]) but within the simulated WBRT target area in 16 (59.26%) patients, and within the CTV (in-field) in 11 (40.74%) patients. None of the patients had extracranial recurrence of the tumor. Of the 11 patients who achieved CR after the initial treatments, 9 (81.82%) had PCNSL recurrences in the out-field area but within WBRT target area; of the 13 patients with a single lesion at the initial treatment, 11 (84.62%) experienced PCNSL recurrence in the out-field area but within WBRT target area.@*CONCLUSIONS@#Systemic therapy combined with WBRT still remains the standard treatment for PCNSL patients, especially those who achieve CR after treatment or have a single initial lesion. Future prospective studies with larger sample sizes are needed to further explore the role of low-dose WBRT in PCNSL treatment.

Policy analysis of high-quality development of traditional Chinese medicine based on PMC index model / 中国药房

OBJECTIVE To provide reference for the optimization of development policy of traditional Chinese medicine. METHODS ROSTCM text mining analysis software was adopted to screen the literature preliminarily ，the PMC policy index model was built ，and the results by PMC index and visual PMC surface were analyzed. RESULTS & CONCLUSIONS A total of 33 policies related to traditional Chinese medicine were included ，and 10 primary variables and 46 secondary variables were set. The average PMC index of 33 policies was 6.15，of which 2 were excellent policies and the rest were good policies. Among the primary variables ，the scores of policy openness ，policy evaluation and policy field were relatively high ，while the scores of release time ，policy level and policy type were low. The analysis of sink index and secondary variables showed that the macro planning of national policies was not specific enough in terms of policy objectives and contents ，with low score ，while the local policies were usually planned in detail. Generally speaking ，there is still much room for improvement in the policies related to the development of traditional Chinese medicine in terms of policy system construction ，government investment ，talent construction ， financing supporting policies ，market access rules ，responsible subjects and legal guarantee.

Analysis on the efficacy and safety of fibrinolytic therapy in patients with acute ST-segment elevation myocardial infarction during the COVID-19 epidemic / 中华心血管病杂志

Objective: To evaluate the efficacy and safety of fibrinolysis strategy in patients with acute ST-segment elevation myocardial infarction (STEMI) during the COVID-19 epidemic, and to provide reference value for optimization of fibrinolytic process on the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff. Methods: The efficacy and safety of fibrinolysis were retrospectively analyzed in 7 patients with acute STEM, who hospitalized from February 29, 2020 to April 3, 2020 in the Department of Cardiology, Wuhan Union Hospital of Tongji Medical College, Huazhong University of Science and Technology. To optimize the fibrinolytic process on the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff, a full-time medical team in charge of fibrinolysis under third-grade protection was established. The acute STEMI patients were treated immediately in a fixed and isolated area in emergency department before receiving green channel fibrinolysis. Blood samples for complete blood count, COVID-19 antibody test and nasopharyngeal swab samples for COVID-19 nucleic acid test were made before fibrinolysis, while the chest CT examination was accomplished after fibrinolysis. By comparing differences of time from the first electrocardiogram (ECG) to fibrinolysis before and after the improvement of fibrinolytic process, the effect of optimization of the fibrinolytic process was evaluated. Results: In the present study, seven patients with acute STEMI received fibrinolysis therapy, 6 of them achieved reperfusion and no bleeding was observed in all of the patients. Five out of the 7 patients were hospitalized after fibrinolysis, and the hospitalization days were 19.6 days on average. By following up to April 14, 2020, none of the 7 patients died. The first 2 patients were treated according to the routine medical procedure and the time from the first ECG to fibrinolysis were 201 and 106 minutes, respectively. After the optimization of the fibrinolytic process, the time from the first ECG to fibrinolysis of the last 5 patients were 42, 46, 51, 43 and 54 minutes, respectively，which was significantly shorter than that before optimization. Conclusions: During the COVID-19 epidemic, fibrinolysis in patients with acute STEMI is safe, effective and easy to implement. Therefore, it is recommended as the top priority for the patients with acute STEMI with indications for fibrinolysis. On the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff, the duration of myocardial ischemia can be shortened by optimization of the fibrinolytic process.

Clinical effect of laparoscopic ovarian endometriosis cyst resection and the influence of different operative methods on follicle loss / 局解手术学杂志

Objective To analyze the clinical effect of laparoscopic ovarian endometriosis (EMs) cyst resection and the influence of different operative methods on follicle loss.Methods Selected 86 EMs patients with laparoscopic ovarian cyst resection in our hospital from January 2013 to January 2016 and randomly divided them into two groups.The control group adopted traditional blunt tearing method,while the observation group adopted sharp isolating method.The specimen thickness along with the number,thickness and grading of specimen with ovarian cortex at hilus orarii,middle part of ovarian fossa and ovarian fossa were observed.Meanwhile,the influence on ovarian function and follicle loss of the two operation methods were compared.Results The specimen thickness close to the hilus orarii was more than that of the ovarian fossa and the middle part of ovarian fossa (t =4.474,t =3.520,P ＜ 0.001).The thickness of specimen with ovarian cortex at ovarian fossa was significantly less than that of the middle part of ovarian fossa and the hilus orarii (t =1.705,t =4.428,P =0.046,P =0.000).The number of specimen ovarian cortex grading of 3 to 4 at hilus orarii was 20,which was significantly more than 2 at the ovarian fossa and 2 at the middle part(x2 =19.790,x2 =19.790,P ＜ 0.001).The specimen thickness and ovarian cortical thickness of the middle part of the observation group were less than those of the control group (t =3.897,t =2.166,P =0.000,P =0.017).The specimen number of ovarian cortex at the hilus orarii was significantly less than the control group(x2 =5.512,P =0.019),and the specimen thickness and the ovarian cortex thickness were obviously less than those of the control group (t =4.992,t =2.349,P =0.000,P =0.011).After operation,the differences between FSH,LH,and E2 levels in the two groups were not statistically significant(P ＞ 0.05),but the ovarian sinus follicle number and ovarian volume of the observation group were significantly more than those of the control group (t =7.181,t =10.921,P ＜ 0.00 001).The pregnancy rate of the observation group was 60.0％,which was significantly higher than 43.75 ％ of the control group (x2 =5.289,P =0.021).Conclusion The laparoscopic ovarian EMs cyst resection can cause the great loss of follicle in the progress of resecting cyst at hilus orarii,and advanced sharp separation can obviously reduce the loss of normal ovarian follicles and cause smaller influence on ovarian function.

A Novel Method for Analysis of Tyrosine Phosphopeptides Based on a Centrifugal Enrichment Device / 分析化学

Protein tyrosine phosphorylation is an important post-translational modification and has become one of the most active areas in proteome research in recent years. Protein tyrosine phosphorylation plays a key regulatory role in the numerous signal transduction processes and in the occurrence & development of tumor. The study of tyrosine phosphorylation and activity of it corresponding tyrosine kinases is of great significance for the research of drug targets for cancer treatment. However, tyrosine phosphorylation only represents less than 0. 1% of the total cellular protein phosphorylation. Therefore, there is a great challenge to identify tyrosine phosphorylation in real complex samples. In this work, a new centrifugal device by combining application of titanium dioxide ( TiO2 ) and C18 reversed phase packing materials for phosphopeptide enrichment and separation was developed, which led to simplified procedure, reduced sample loss and minimized interference.This new centrifugal device was made of pipette tips, adapters and Eppendorf tubes. Sample loading, phosphopeptides enrichment, washing, eluting and separation were combined into this device and could be achieved by simple centrifugation. This device was capable of paralleled sample processing with improved analysis throughput. Tandem enrichment by anti-phosphotyrosine antibody resulted in efficient enrichment and large scale identification of phosphotyrosine peptides by mass spectrometry. As a result, 967 phosphotyrosine sites corresponding to 545 proteins were successfully identified from 5 mg of mouse liver proteins, demonstrating the robustness and potential of this new strategy.

Honokiol combined with Gemcitabine synergistically inhibits the proliferation of human Burkitt lymphoma cells and induces their apoptosis / 中国实验血液学杂志

This study was aimed to investigate the effect of Honokiol (HNK) combined with Gemcitabine (GEM) on the proliferation and apoptosis of human Burkitt lymphoma Raji cells. Cell proliferation was detected by CCK-8 method to study the role of Honokiol and Gemcitabine in Raji cells. The cell apoptosis and cell cycle status were analyzed by flow cytometry. The level of apoptosis-related protein BCL-2 was measured with Western blot. The results showed that compared with cells treated with mentioned above drugs alone, the proliferative potential of cells in combination group was significantly inhibited (P < 0.01) and the inhibition rate was related to the concentration and action time of HNK; and apoptosis rate markedly increased (P < 0.01), while most Raji cells were arrested at G0/G1 phase and decreased in S phase after treatment with combination of two drugs; the expression of BCL-2 protein decreased (P < 0.01). It is concluded that Honokiol combined Gemcitabine can synergistically inhibit the proliferation, induce cell apoptosis, and down-regulate the expression of BCL-2 in Raji cells. The possible mechanism of synergistic effect may be related with arrest of cell cycle at G0/G1 phase and downregulation of the expression of BCL-2.
