OBJECTIVE To establish fingerprint， chemical pattern recognition and multi-component quantification analysis of Sanzi powder， and evaluate its quality. METHODS HPLC method was adopted. The fingerprints of 15 batches of Sanzi powder were established by using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition）. Cluster analysis， principal component analysis and orthogonal partial least squares-discriminant analysis were also conducted. The variable importance in projection （VIP） value greater than 1 was used as the index to screen the differential markers， and the contents of the differential markers were determined by the same HPLC method. RESULTS A total of 21 common peaks in the HPLC fingerprints of 15 batches of Sanzi powder were calibrated， and the similarities of them were 0.994- 0.999； 6 common peaks were identified， including gallic acid （peak 3）， garminoside （peak 10）， corilagin （peak 11）， chebulinic acid （peak 16）， ellagic acid （peak 18）， crocin Ⅰ （peak 19）. According to the results of cluster analysis， YKD2024LH005，No.YKD2023LH062） principal component analysis and orthogonal partial least squares-discriminant analysis， 15 batches of samples could be clustered into two categories： S1， S5， S7， S9， S14 were clustered into one category； S2-S4， S6， S8， S10-S13， S15 were clustered into one category. VIP values of 11 differential components such as corilagin， chebulinic acid and ellagic acid were higher than 1. Among 15 batches of samples， the contents of corilagin， chebulinic acid and ellagic acid ranged 2.667-5.152， 9.506- 13.522， 0.891-1.811 mg/g. CONCLUSIONS Established HPLC fingerprint and multi-component quantification analysis of Sanzi powder are rapid and simple， and can be used for quality evaluation of Sanzi powder by combining with chemical pattern recognition. Eleven components such as corilagin， chebulinic acid and ellagic acid are differential markers affecting the quality of Sanzi powder.

Objective:To discuss the feasibility and safety of robot-assisted laparoscopic retroperitoneal tumor resection in prone position.Methods:From August 2023 to January 2024, a total of eight patients with retroperitoneal tumors from the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed, including two males and six females. The average age was (47.4±12.5) years, average BMI was (24.4±3.5) kg/m 2 and median ASA grade was 2(2, 3). Retroperitoneal tumors were identified preoperatively through CT or MRI. The imaging revealed 4 cases of adrenal tumors located on the left side, 2 on the right side, and 2 non-adrenal tumors situated on the left side. The preoperative diagnoses included 2 cases of non-functional adrenal tumors, 2 cases of pheochromocytoma, 1 case of Cushing’s syndrome, 1 case of metastatic renal cell carcinoma, and 2 cases of non-adrenal tumors. Robot-assisted laparoscopic retroperitoneal tumor resection was performed with all patients in prone position. The inferior margin of the fourth lumbar vertebra (L4) was determined by the line connecting the highest points of the iliac crests bilaterally. Subsequently, the inferior margins of the L1-L3 vertebrae were sequentially identified. The surgical field was then divided into three equal segments, utilizing the posterior midline of the spine and the midaxillary line as boundaries. The medial division was situated approximately at the lateral border of the vertical spinal muscles, while the lateral division was placed near the tip of the 12th rib. A longitudinal incision of approximately 3 cm in length was created within the lateral division between L2 and L3 for the insertion of a camera trocar. The extraperitoneal space was subsequently dilated using a self-made balloon, and two 8 mm trocars were placed as operative ports along the medial division and the midaxillary line, respectively, under finger guidance. Assistance trocars, one or two 12 mm in diameter, were introduced above the level of the iliac crest. During the operation, the extraperitoneal adipose tissue was removed and the Gerota's fascia was opened. For non-adrenal retroperitoneal tumours, the major blood vessels around the tumour were suspended and fixed, by titanium clips or Hem-o-lok clips to dissect the small arteries and veins, and the tumour was carefully isolated and completely resected. For adrenal tumours, the fat capsule around the upper pole of the kidney were removed, the adrenal gland was exposed, and then the tumour was removed completely along its capsule. If total adrenalectomy is performed, the central adrenal vein was clamped and dissected. The periphery of the adrenal gland was gradually dissected until the adrenal gland was completely removed.The perioperative data, including patient positioning time, trocar placement time, operation time, intraoperative blood loss, postoperative complications, postoperative hospital stay, and postoperative drainage tube removal time, as well as recurrence and metastasis, were recorded.Two patients underwent partial nephrectomy due to renal tumor, and only the time for retroperitoneal tumor resection was included in calculating operation time. Results:All 8 surgeries were successfully completed without dramatic blood pressure fluctuations.There was no conversion to open surgery or abdominal organ injury. The patient positioning time was (5.1±0.4) minutes, trocar placement time was (16.6±1.3) minutes, operation time was (28.8±13.8) minutes, intraoperative blood loss was (65.0±28.7) ml, postoperative hospital stay was (3.6±0.9) days, and drainage tube removal time was (2.8±1.0) days. No intraoperative or postoperative blood transfusions were required. Postoperatively diagnosed pathologies included: 2 cases of adrenal pheochromocytoma, 2 cases of adrenal sebaceous adenoma, 2 cases of retroperitoneal schwannoma, 1 case of adrenal myelolipoma, and 1 case of adrenal metastatic renal cell carcinoma. The average tumor size for all patients was (4.3±1.5) cm. After a follow-up of 2.0-7.2 months, there were no recorded postoperative complications, including haemorrhage, infections, acute hypotension, or adrenocortical insufficiency. Additionally, no evidence of tumor recurrence or metastasis was observed up during foolow-up.Conclusions:Robot-assisted laparoscopic retroperitoneal tumor resection in prone position could be a safe and feasible surgical approach with short operative time, low bleeding, and fast postoperative recovery.

【Objective】 To establish a management information system (referred to as the system) for plasma collection stations in Zhejiang province, so as to explore the current situation of plasma donors and implement effective supervision in Zhejiang. 【Methods】 The system was developed and connected to four plasma collection stations that were officially operating in Zhejiang in terms of plasma station setting and approval, as well as the publicity, recruitment and management of plasma donors, information management of the whole process of plasma collection, management of deferral plasma donors, plasma quality management and administrative supervision etc. Relevant plasma donor information was uploaded to the system by each plasma station, and information before (January 2016 to December 2020) and after (January 8, 2021 to June 2021) the system was collected. Information included the number of plasma donors/donations, demographic information of eligible plasma donors in the past 5 years, the type of plasma donors, and the deferral donors after the system was activated. The online approval of Plasma Donation Certificate and the intelligent supervision of key points of plasma apheresis stations in Zhejiang were also conducted. The frequency and composition ratio were described, and chi-square test was used for statistical analysis. 【Results】 The system (V1.0) was established and was officially launched on January 8, 2021, realizing the interconnection of blood donation and plasma donation information as well as the unified management of 24 quality indicators. Since the system was applied (January 8, 2021-June 2021), the proportion of donors both donated blood and plasma over the province was 3.56 (832/23 389), and 352 deferred donors were masked by the system. And 30.11% (106/352) , who intended to donate plasma, were deferred due to insufficient interval after blood donation; 11.65% (41/352) due to permanent masking in blood donations; 23.86% (23.86%) , who intended to donate blood, were deferred due to insufficient interval after plasma donation ( 84/352); 34.38% (121/352) due to permanent masking in plasma donations. The median approval rate of four plasma stations applying for Plasma Donation Certificate before the system (January 1, 2016 to January 7, 2021) and after the system (January 8 to June 2021) were 93.38% (10 609/11 361) vs 99.50% (2 602/2 615). Before the system was put into launch, the ratio of male to female donors and the proportion of regular donors showed an overall upward trend, while the age decreased slightly. The median proportion of women in the past 5 years was 61.52 %, significantly higher than that in last 6 months after the launch(58.86%). 【Conclusion】 The application of the system can realize information interconnection between blood centers and plasma collection stations in Zhejiang as well as the real-time supervision of plasma collection process, which is helpful to overcome the shortcomings in plasma donor management.

postoperative survival and 38 had tumor recurrence or metastasis.(3) Risk factors analysis of perioperative complications.① Results of univariate analysis showed that age,body mass index (BMI),preoperative hemoglobin,preoperative serum albumin and XAPD were related factors affecting perioperative complications of laparoscopic distal gastrectomy (x2 =10.289,7.427,5.269,5.481,4.285,P＜ 0.05).② Results of multivariate analysis showed that age,BMI,preoperative serum albumin were independent related factors affecting perioperative complications of laparoscopic distal gastrectomy (odds ratio =1.033,1.118,0.937,95％ interval confidence:1.011-1.057,1.025-1.219,0.887-0.990,P＜0.05).(4) Influence of body shape related indexes on intraoperative situations and postoperative recovery.① Results of Pearson univariate correlation analysis showed correlations between UAPD,XAPD,CAD,CATD and volume of intraoperative blood loss (r=0.107,0.169,0.179,0.106,P＜0.05),between UAPD,XAPD,CAD and the number of lymph nodes dissected (r=-0.137,-0.143,-0.173,P＜0.05),between USCF,XAPD and time to postoperative anal exsufflation (r =0.122,0.109,P＜0.05),between USCF,XAPD,CAD and time for initial fluid diet intake (r=0.132,0.108,0.132,P＜0.05),between USCF,XAPD and duration of postoperative hospital stay (r=0.116,0.100,P＜0.05).② Results of liner regression model analysis showed a positive correlation between CAD and volume of intraoperative blood loss (r =6.776),a negative correlation between CAD and the number of lymph nodes dissected (r =-0.841),with statistically significant differences (t =2.410,-1.992,P＜ 0.05);a positive correlation between USCF and time to postoperative anal exsufflation (r=0.170),between USCF and time for initial fluid diet intake (r=0.365),between USCF and duration of postoperative hospital stay (r=0.636) respectively,with statisticallysignificant differences (t =2.188,1.981,2.107,P＜ 0.05).Conclusions Abdominal shape can influence intraoperative situations and postoperative recovery of laparoscopic distal gastrectomy,but cannot increase risks ofperioperative complications.Age,BMI and preoperative serum albumin are independent related factors affecting perioperative complications of laparoscopic distal gastrectomy.

LADG has an advantage of the lymph node dissection in the upper region of pylorus compared with posterior approach,and it also is better for patients with later tumor staging,higher BMI and bigger tumor.

Objective To explore the effects of Valpar Component Work Sample on Parkinson's disease (PD). Methods From June, 2015 to June, 2017, 40 patients with PD were randomly divided into control group (n=20) and observation group (n=20). Both groups received routine treatment and occupational therapy, while the observation group accepted rehabilitation with Valpar Component Work Sample in addition, for eight weeks. They were assessed with Unified Parkinson's Disease Rating Score II and III (UPDRSII and UPDRSIII), Mini-Mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA) and the Parkinson's Disease Questionnaire-39 (PDQ-39) before and after treatment. Results The scores of UPDRSII, UPDRSIII, MMSE, HAMD, and HAMA, and Summary Index of PDQ-39 improved in both groups (t>2.864, P<0.05) after treatment, and improved more in the observation group than in the control group (t>2.237, P<0.05). Conclusion Combined with Valpar Component Work Sample may further improve the activities of daily living, motor, cognitive function, depression and anxiety, and then quality of life in patients with PD.

Objective To summary the experience of AngioJet mechanical thrombectomy for the treatment of acute deep venous thrombosis (DVT) of lower extremity.Methods Clinical data of 28 patients suffering from acute DVT of lower extremities treated by AngioJet mechanical thrombectomy were analyzed retrospectively from October 2013 to February 2015.Venous recanalization was graded by a thrombus score based on pre-and post-treatment venography.Follow-up was performed by Doppler ultrasound and clinical evaluation.Results Twelve patients were planted temporary vena cava filters.The average length of hospitalization was (3.9 ± 1.1) days.The average operation time was (1.2 ± 0.4) hours.The dosage of urokinase was (320 ± 120) × 104 U and heparin was (46 ± 10)mg during surgery.The average reduction of hemoglobin was (7.5 ± 2.6) g/L.Two patients (Grade Ⅰ thrombolysis) were converted to catheter-directed thrombolysis (CDT).There were 10 (35.7％) cases achieving grade Ⅱ and 16 (57.1％) cases achieving grade Ⅲ,respectively.Technique success rate were 92.9％.Minor bleeding events occurred in 2 patients.Nine (32.1％) patients had stents implanted.One year follow-up found patent deep venous in 26 (92.9％) patients and stent patency rate was 88.9％ (1/9).Two (7.1％) cases developed mild postthrombotic syndrome (PTS).Conclusion AngioJet is a safe and effective tool to treat acute DVT accelerating thrombolytic therapy,and reducing bleeding complications.

Programmed cell death 4 (PDCD4) is a RNA-binding protein that acts as a tumor suppressor in many cancer types, including colorectal cancer (CRC). During CRC carcinogenesis, PDCD4 protein levels remarkably decrease, but the underlying molecular mechanism for decreased PDCD4 expression is not fully understood. In this study, we performed bioinformatics analysis to identify miRNAs that potentially target PDCD4. We demonstrated miR-181b as a direct regulator of PDCD4. We further showed that activation of IL6/STAT3 signaling pathway increased miR-181b expression and consequently resulted in downregulation of PDCD4 in CRC cells. In addition, we investigated the biological effects of PDCD4 inhibition by miR-181b both in vitro and in vivo and found that miR-181b could promote cell proliferation and migration and suppress apoptosis in CRC cells and accelerate tumor growth in xenograft mice, potentially through targeting PDCD4. Taken together, this study highlights an oncomiR role for miR-181b in regulating PDCD4 in CRC and suggests that miR-181b may be a novel molecular therapeutic target for CRC.
