For many years, TCM formula granules, as a new form of decoction pieces reform, have been favored by people with its three features—Three Efficacy, Three Small and Five Conveniences. As a result, it has become the ideal product in the course of TCM internationalization. In the face of growing sales, to formulate its standard becomes imminent. Therefore, how to establish a system that is unique to standardization of TCM formula granules has become a research hotspot of scholars. This article summarized Results of recent research on the preparation, quality control, pharmacology studies and clinical evaluation of TCM formula granules, with a purpose to put forward relevant suggestions, and provide references for standardization of TCM formula granules.

Objective To understand the epidemiological characteristics and clinical features of Zika virus disease,and to improve its prophylaxis and treatment.Methods The first case with imported Zika virus disease in China was retrospectively reported and analyzed.The literature of Zika virus infection in human was reviewed.Results This patient was the first case with imported Zika virus disease in China who presented with typical clinical characteristics and had clear epidemiological history.All the contacts were test negative for Zika virus nucleic acid.Literature retrieval showed evidence of Zika virus propagation in more than 40 countries in Africa,Asia,and Americas.The majority of patients presented with mild symptoms and the main prevention measures included mosquito control and improved awareness of personal protection.Conclusions Human infected with Zika virus often shows recessive infection.Only a small part develop disease and have generally good prognosis with supportive treatment.

Objective To evaluate the left ventricular systolic dyssynchrony in patients with left ventricular apical ballooning syndrome (LVABS) quantitatively by real-time three-dimensional echocardiography(RT-3DE) and its correlation with left ventricular ejection fraction(LVEF).Methods 7patients with LVABS were enrolled in this study.The images of left ventricle in full volume mode were obtained by RT-3DE in the different time (just after admission,4 weeks and 8 weeks).Post-processing software of 4D LV Volume Tom-Tec was used for calculation of EF and 16-segmental time-volume curves was obtained.The time to the point with minimal systolic volume(Tmsv) of each segment was calculated and by which the following indexes of systolic dyssynchrony were derived:Tmsv16-SD/Dif,Tmsv-basalSD/Dif,Tmsv-mid-SD/Dif and Tmsv-apical-SD/Dif.The correlation between systolic dyssynchrony index (SDI) and LVEF was analysed.Results ① The Tmsv16-SD/Dif,Tmsv-basal-SD/Dif,Tmsv-mid-SD/Dif and Tmsv apical-SD/Dif of left ventricle in the patients of 4 weeks and 8 weeks were smaller than those of the patients just after admission.There were significant differences among them(all P ＜0.05).②The more SDI increased,the more LVEF decreased,and vice versa.SDI was negatively associated with LVEF in the different time of admission (just after admission:r =-0.758; 4 weeks:r =-0.831 ; 8 weeks:r =-0.889;all P ＜0.05).Conclusions Left ventricular systolic dyssynchrony of severe degree is observed in patients with LVABS just after admission.But the condition of dyssynchrony has been improved gradually after 4 weeks and 8 weeks.SDI is negatively correlated with LVEF.

Objective To investigate the therapeutic efficacy of minimally invasive modified transforaminal lumbar interbody fusion (TLIF) combined with unilateral nail holding system in patients with extreme lateral lumbar disc herniation.Methods Thirty-eight patients with extreme lateral lumbar disc herniation were divided into minimally invasive modified TLIF combined with unilateral nail holding system group (observation group) and conventional open TLIF group (control group) with 19 cases each according to random digital table method.The therapeutic efficacy was compared between 2 groups.Results Surgery was completed successfully in 2 groups,and there was no perioperative complications.The amount of bleeding and hospital stay length in observation group were significantly less than those in control group:(152 ± 82) ml vs.(258 ± 104) ml and (6.5 ± 2.3) d vs.(12.7 ± 3.6) d,and the rate of fusion and score of Japan Orthopaedic Association 6 months after surgery in observation group were significantly higher than those in control group:18/19 vs.10/19 and (14.5 ± 2.1) scores vs.(12.6 ± 1.9) scores.There were statistical differences (P ＜ 0.01).There was no statistical difference in complications between 2 groups (P ＞ 0.05).Conclusion Minimally invasive modified TLIF combined with unilateral nail holding system in patients with extreme lateral lumbar disc herniation has less blood loss and shorter hospital stay,and it is effective and safe.

Objective:To explore the clinical efficacy of dual-kidney transplantation from infant donors to adult recipients.Methods:From December 2012 to November 2020 in Organ Transplant Center First Affiliated Hospital Sun Yat-sen University, rertrospective reviews were conducted for clinical data of 25 pairs of infant donors and adult recipients. The survival rates were calculated for both recipients and transplanted kidneys at Year 1/3/5 post-transplantation. And the postoperative recovery status and the postoperative incidence of adverse events of recipients were observed.Results:The survival rates of recipients were all 95.8% at Year 1/3/5 and those of transplanted kidney and dealth-cancelling transplanted kidney all 87.2%. One case died due to acute inferior-wall cardiac infarction while three others lost renal functions for vascular thrombosis, ureteral stenosis and urinary fistula. Except for loss of renal function and death, the postoperative estimated golmerular fitration rate was (99.35±21.78), (103.11±29.20) and (114.99±28.55) ml/(min·1.73 m 2) at Year 1/2/3 respectively. Conclusions:Selecting proper recipients, standardizing donor acquisition and surgical procedures and strengthening perioperative managements may expand the donor pool. The overall outcomes are excellent for adult recipients with dual-kidney transplantation from donations after infants' death.

Background Suicidal ideation serves as a sensitive predictive indicator for non-suicidal self-injury(NSSI)behavior,and NSSI behavior brings profound effects to both mental and physical health of senior high school students.Existing studies have made exploration on the relationship among insomnia,anxiety and NSSI behavior in the general population,but the internal mechanism of NSSI behavior in senior high school students with suicidal ideation requires further study.Objective To explore the pathway of anxiety between insomnia and NSSI behavior in senior high school students,so as to provide references for the intervention on NSSI behavior in such demographic.Methods From December 10 to 15,2021,cluster sampling was adopted to select 2 572 senior high school students across three senior high schools in Hubei Province as the research objects.Assessment was conducted by using Insomnia Severity Index(ISI),Generalized Anxiety Disorder Scale-7 item(GAD-7)and Adolescents Self-Harm Scale.Spearman correlation analysis was conducted to examine the correlation among scores of scales finished by senior high school students with suicidal ideation.Model 4 from the SPSS 20.0 Process 4.2 was employed to test the mediating path of anxiety between insomnia and NSSI behavior.Results A total of 2 421 valid questionnaires(94.13%)were recovered,which revealed 554 cases(22.88%)with suicidal ideation and 408 cases(16.85%)with NSSI behavior.The scores of ISI,GAD-7 and Adolescents Self-Harm Scale of senior high school students with suicidal ideation were higher than those of students without suicidal ideation(Z=17.124,20.611,21.314,P<0.01).As correlation analysis showed,the ISI score of senior high school students with suicidal ideation was positively correlated with scores of GAD-7 and Adolescents Self-Harm Scale(r=0.646,0.354,P<0.01),and GAD-7 score was positively correlated with the score of Adolescents Self-Harm Scale(r=0.375,P<0.01).Among senior high school students with suicide ideation,anxiety acted in a mediating role between insomnia and NSSI behavior,with effect value of 0.111(95%CI:0.053～0.185),accounting for 53.88%of the total effect.Conclusion Insomnia of senior high school students with suicidal ideation can not only directly affect NSSI behavior,but also indirectly affect NSSI behavior through anxiety.

Intramesorectal lymph node metastasis after radical surgery of prostate cancer is rare in clinical practice. This paper reported 2 cases of intramesorectal lymph node metastasis and resection after operation for prostate cancer. Patient 1 underwent laparoscopic radical prostatectomy 5 years ago, who was followed up closely after surgery, and was diagnosed with mesorectal lymph node metastasis by MRI examination. Patient 2 underwent robot-assisted laparoscopic radical prostatectomy 2 months ago, who was followed up by pelvic MRI and mesorectal lymph node metastasis was revealed. Both patients underwent fluorescence laparoscopic mesenteric lymphadenectomy in our department. With 4 to 6 month of follow-up after surgery, MRI examination showed no recurrence of tumor.

Objective To explore the clinical outcome of renal transplantation and analyze the risk factors influencing the kidney allograft survival after transplantation.Methods The clinical data of 524 cases of renal transplantation between January 2007 and December 2015 were retrospectively analyzed.Serum creatinine was determined,and glomerular filtration rate(GFR) was estimated.The 1-,2-and 3-year patient and graft survival after transplantation was calculated.Adverse events were recorded.Results The median follow-up time was 17.2 months.The 1-,2-and 3-year graft survival rate after transplantation was 97％,95.8％ and 95.3％,respectively.The 1-,2-and 3-year patient survival rate after transplantation was 97.8％,97％ and 97％,respectively.The eGFR was (67.6 ± 24.1),(68.9±24.2) and (72.7 ± 26.2) ml·min-1 ·1.73 m-2 at 1st,2nd and 3rd year after transplantation.The incidence of delayed graft function(DGF) was 20.6％ (108/524).Multivariate analysis revealed donor type (P =0.005) and the terminal creatinine (P＜0.001) were the independent risk factors of DGF.Elder recipients (P =0.004),recipients with diabetes(P =0.031),preoperative positivity of panel reactive antibody(PRA) (P =0.023),and donor with hypertension (P =0.046) were risk factors influencing the kidney allograft survival.Conclusion Kidney transplantation showed good outcomes at 3rd year after transplantation.The recipient age,recipient's history of diabetes,preoperative PRA and donor's history of hypertension are independent risk factors for renal graft survival.

Objective To analyze the 10-year survival outcome and failure patterns for patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT),aiming to provide reference for optimized treatment for NPC.Methods Clinical data of 866 patients with NPC receiving IMRT from January 2001 to December 2008 were retrospectively analyzed.Survival analysis was performed using the Kaplan-Meier estimator.Univariate analysis was carried out by log-rank test and multivariate analysis was performed using Cox proportional hazards model.Results The median follow-up time was 132 months.The 10-year local recurrence-free survival (LRFS),distant metastasis-free survival (DMFS),progression-free survival (PFS) and disease specific survival (DSS) were 92.0％,83.4％,75.7％ and 78.6％,respectively.A total of 210 patients died including 124 patients (59.0％) from distant metastasis,which was the primary cause of death,and 47 (22.3％) from local regional recurrence.Independent negative factors of DSS included age＞50 years (P=0.00),LDH ≥ 245 IU/L (P=0.00),Hb＜ 120 g/L (P=0.01),T2-T4 staging (P=0.00),N1-N3 staging (P=0.00) and GTV-nx＞20 cm3(P=0.00).The 10-year LRFS,DMFS and DSS of stage Ⅱ NPC patients did not significantly differ after IMRT alone and chemoradiotherapy (P=0.83,0.22,0.23).For patients with stage Ⅲ NPC,the 10-year LRFS and DSS in the chemoradiotherapy arm were significantly higher than those in the IMRT alone (P=0.01,0.01),whereas no statistical significance was observed in the DMFS between two groups (P=0.14).The overall survival of stage Ⅳa+Ⅳb NPC patients is relatively poor.Conclusions IMRT can improve the long-term survival of NPC patients.Distant metastasis is the primary failure pattern.Patients with stage Ⅰ-Ⅱ NPC can obtain satisfactory survival outcomes after IMRT alone.The addition of chemotherapy can further enhance the LRFS and DSS of stage Ⅲ NPC patients.However,the optimal therapeutic strategy remains to be urgently investigated for stage a+ Ⅳb NPC patients.

Objective:To examine the feasibility and safety of endoscopic subcutaneous mastectomy and immediate reconstruction via a small skin incision approach without gas and mesh for early breast carcinomas.Methods:We analyzed 7 patients diagnosed with breast cancer who underwent an endoscopic subcutaneous mastectomy and immediate reconstruction from Jun. to Nov. 2021 using a gasless and meshless small skin incision approach at the Department of Thyroid and Breast Surgery, the First Affiliated Hospital of USTC. Mean age was 44.9 (29-63) years. Clinical stage, postoperative complications and other data of patients were collected. Patients were required to fill in BREAST-Q scale anonymously before and during postoperative follow-up. The difference was considered significant for P < 0.05. Results:The tumors were all unilateral and solitary lesions, with a mean diameter of 1.74 (0-5) cm. The average distance of mass from the nipple on imaging was 2.11cm (range 0 to 4) . Postoperative pathological clinical stage,1 patient was in Tis, 3 patients were in stage I, 2 patients were in stage II and a pathological complete response was achieved in one patient (ypT0pN0cM0 CR) . The mean operative time was 245.3 (195-316) min, the mean intraoperative bleeding volume was 37.1ml, the mean postoperative hospital stay was 5.1 d, and the median follow-up time was 8.8 (6-11.2) months. All the 7 patients had incision healing at the first stage, and no complications such as infection, incision complications, capsular contracture, nipple-areola complex or skin flap necrosis, removal or displacement of breast implant occurred. No local recurrence or metastasis was detected during the follow-up period. Compared with preoperative, the scores of postoperative psychosocial status, chest wall status were lower ( P<0.05) , but still ideal, while breast satisfaction and sexual satisfaction scores were not significantly different from preoperative baseline ( P>0.05) . Conclusion:This study indicates that endoscope-assisted breast reconstruction with gasless and meshless is a safe and feasible surgical intervention method for early breast cancer, with good cosmetic effects, and can be promoted as a new type of breast reconstruction.
