【Objective】 To explore the relationship between hidden blood loss （HBL） and risk factors in percutaneous endoscopic interlaminar discectomy （PEID）. 【Methods】 We retrospectively analyzed 113 patients （67 males and 46 females， aged 21-71 years old） with lumbar disc herniation （L5-S1 level） who underwent PEID with complete clinical data in the Department of Spinal Surgery of Subei People’s Hospital Affiliated to Yangzhou University from January 2018 to August 2020. The collected data included general patient indicators （age， body mass index and gender）， underlying diseases （hypertension and diabetes）， laboratory tests （prothrombin time， activated partial thromboplastin time， fibrinogen， hematocrit and hemoglobin level）， imaging related parameters （grade of intervertebral disc degeneration， interlaminar space height and soft tissue thickness of interlaminar approach）， intraoperative significant blood loss and operation time. According to the Gross formula， total blood loss and HBL during operation were calculated. And the risk factors of HBL was analyzed. 【Results】 The total perioperative blood loss was （394.85±130.50） mL， and HBL was （337.09±124.98） mL which accounted for 85.4% of the total blood loss. Multivariate linear regression analysis showed that operation time （P<0.001） and disc degeneration grade （P=0.020） were independent risk factors of HBL. 【Conclusion】 HBL is the main cause of blood loss during PEID， and operation time and disc degeneration grade are independent risk factors that affect the amount of HBL.

Non-coding RNA refers to a class of RNAs that cannot encode proteins, and they play a very important role in regulating cellular activities. Pulmonary arteryhypertension is a group of diseases characterized by progressive elevation of pulmonary vascular pressure. Its pathogenesis is complex and its influencing factors are numerous. The study found that non-coding RNA, as a transcription product that does not participate in translational functions, plays an important role in the pathogenesis of patients with pulmonary arteryhypertension. With regard to the more well-studied and relatively mature circRNAs, lncRNAs, and miRNAs in non-coding RNAs, this article review the pathophysiological processes involved in the formation of pulmonary arteryhypertension.

Objective: To compare the clinical results between arthroscopic anchor suture bridge and Ethibond suture bone tunnel for anterior cruciate ligament (ACL) tibial avulsion fractures. Methods: A retrospective case control study was conducted to analyze the clinical data of 18 patients with ACL tibial avulsion fracture admitted to Wenzhou Central Hospital from June 2012 to June 2017. There were 14 males and four females, aged 12-57 years, with an average age of 31.4 years. According to the Meyers-McKeever classification, there were six patients with type II and 12 patients with type III. Seven patients underwent anchor suture bridge fixation (anchor group), and 11 patients underwent Ethibond suture bone tunnel fixation (Ethibond suture group). The operation time, range of motion (ROM) of knee joint, Lysholm knee score and International Knee Documentation Committee (IKDC) knee score of the two groups were compared before operation and 3, 6 and 12 months after operation. Results: All patients were followed up for 12-36 months, with an average of 20.18 months. The operation time of anchor group [(87.14±8.59)minutes]was longer than that of Ethibond suture group [(71.1±11.5)minutes](P<0.05). The ROM of anchor group and Ethibond suture group was (127.1±8.6)° and (124.1±7.4)° respectively at 3 months after surgery, showing no statistical difference between the two groups (P>0.05). But the functional knee scores (Lysholm score and the IKDC score) revealed better clinical results in anchor group [(91.9±3.0)points, (85.6±4.1) points respectively] than Ethibond suture group [(88.6±3.3)points, (79.9±4.9)points respectively] at 3 months after surgery (P<0.05). There were significant differences between before and after operation within two groups regarding the knee function scores including ROM, Lysholm knee score and IKDC score (P<0.05). Three months after operation, there were significant differences between the two groups in terms of the Lysholm score and IKDC score (P<0.05), but there were no statistical differences between two groups at 6 months and 12 months after surgery (P>0.05). Conclusions Both arthroscopic anchor and Ethibond suture can achieve plane fixation of fracture, but there is no significant difference in the long-term effect of improving knee joint mobility and restoring knee joint function between the two approaches. However, the anchor group can achieve early recovery of knee joint function.

Objective To detect the relationship of pathological grade and stage of bladder cancer with common chromosomal aberrations of urine exfoliated cells by FISH. Methods A total of 99 urine samples were detected by FISH with probes of chromosomes 3,7,17 and 9p21 to collect pathological grade and stage information of bladder tumor tissues. Results (1) The aberrations of chromosome 3 and 17 had significant correlation with pathological grade and stage (P<0.05) but that of chromosome 7 had no correlation with pathological stage (P>0.05), but had correlation with grade (P < 0.05). The aberration of 9p21 had no correlations with pathological grade or stage (P > 0.05). (2)The polysomic chromosomal aberrations of chromosomes 3, 7 and 17 assessed correlated with high-grade and high-stage bladder carcinoma. The 9p21 deletion was found at a significant frequency in low-grade and low-stage lesions, when, 9p21 amplification was found at a significant frequency in high-grade and high-stage lesions. Conclusions Aberrations of the four chromosomes, especially polysomic chromosomal aberrations of the bladder cancer cases could present a possible trend toward greater chromosome increased with tumor grades and progressive stages of invasion.

Objective To study the safety and efficacy of damage control using percutaneous transhepatic biliary drainage (PTBD) in acute cholangitis of severe type (ACST) secondary to intrahepatic choledocholithiasis.Methods The clinical data of 8 patients who received PTBD after hospital admission followed by conventional surgery for ACST when their general condition improved were retrospectively studied.Results All patients received PTBD successfully and the amount of bile drained was 100-400 ml in the first day.The general condition of these 8 patients became better after 24 h and the total bilirubin decreased for about 25-100 mmol/L after 48 h.Three patients with a platelet count of less than 20 × 109/L showed an improved count to more than 50 × 109/L 72 h after PTBD.All patients were operated at different times after the PTBD:2 received T-tube drainage,3 T-tube drainage combined with left hepatectomy,and 3 choledochojejunostomy.Seven patients recovered uneventfully,but 1 developed hepatic failure with the total billurubin rose to more than 200 μmol/L.He was discharged home with the PTBD tube.During the waiting time of 7 days to 3 months before surgery,the tubes were kept patent and no mortality or morbidity such as bleeding,bile leakage,and peritonitis occurred.Conclusions PTBD was a safe and efficacious procedure for patients who were in a serious condition with ACST secondary to intrahepatic choledocholithiasis.It was more likely to be successful as it is minimally invasive and therefore well-tolerented.It reduced the biliary pressure,relieved the ongoing sepsis,and was a good preparatory procedure before any conventional surgery.
