Objective:To explore the efficacy and safety of transurethral anatomical vapor incision technique of prostate (VIT) with six-step method high power side-emitting greenlight laser in the treatment of benign prostatic hyperplasia (BPH).Methods:A retrospective analysis of 82 patients with BPH who used high power side-out green laser in the treatment from October 2018 to June 2020 in Gongli Hospital of Naval Medical University was performed. Among them, 40 patients were treated with six-step method VIT, and 42 patients were treated with photoselective vaporization of prostate (PVP). The two groups of patients were compared in age [(71.1±8.7)years vs.(72.1±7.0)years], prostate volume [75 (68.25, 89.00) ml vs. 73 (63.25, 85.00) ml], and peak urinary flow rate (Q max) [6.20 (5.20, 8.20) ) ml/s vs. 5.9 (4.75, 7.50) ml/s], post-void residual volume (PVR) [74.00 (42.50, 103.75) ml vs. 67.00 (58.00, 84.50) ml], international prostate symptom score (IPSS) [(21.2±5.2) vs. ( 21.0±3.9)], quality of life score (QOL) [5 (4, 6) vs. 5 (4, 6) ], prostate specific antigen (PSA) [6.20 (4.12, 8.43) ng/ml vs. 5.40 (3.88, 7.13) ng/ml ]. In general, there was no statistical difference ( P>0.05). The VIT group adopts the six-step method of marking, removing film, grooving, excision, trimming and crushing. In the PVP group, the prostate tissue was uniformly vaporized layer by layer from the inside to the outside. Perioperative indexes and complications were compared between the two groups. The Q max, IPSS, QOL, PVR and PSA between the two groups before and 3 months after surgery were compared. Results:All patients in the VIT group and PVP group successfully completed the surgery, and there was no case of transfer to TURP or open surgery. The average operation time was [60.00(50.00, 73.75)min vs. 70.00(50.00, 73.75)min] ( P<0.05). There was no significant difference in the amount of postoperative hemoglobin decline[15.00(10.00, 17.75)g/L vs. 16.00(14.00, 19.25)g/L], average bladder irrigation time[1(1, 1)d vs. 1(1, 1)d], indwelling catheterization time[3(3, 3)]d vs. 3(3, 3)d] and hospitalization time in patients after operation[4(3, 4)d vs. 4(4, 4)d] ( P>0.05). All patients had no blood transfusion, second bleeding, readmission, TURS, urethral stricture and urinary incontinence.There were 2 cases (5.0%) of postoperative urinary tract infection in the VIT group and 9 cases (21.4%) of postoperative urinary tract infection in the PVP group ( P<0.05), and they were cured after anti-inflammatory treatment. Three months after operation, Q max, IPSS, QOL, PVR and PSA in the two groups were significantly improved compared with preoperatively. Among them, the differences of IPSS [(5.7±2.5) points vs. (7.5±2.8) points] and PSA [2.65(2.10, 3.90)ng/ml vs. 4.00(2.45, 4.45)ng/ml] in the VIT group and PVP group after operation were statistically significant ( P<0.05). Conclusions:Applying the six-step method high power side-emitting greenlight laser transurethral anatomical VIT to treat BPH, there is less intraoperative and postoperative bleeding, short operation time, significant decrease in PSA, and fewer complications. It is a safe and effective minimally invasive technology for the treatment of BPH.

Objective:To explore the clinical effect and safety of interventional treatment of autogenous arteriovenous fistula(AVF) stenosis.Methods:From July 2017 to September 2018, 96 patients with arteriovenous fistula stenosis and occlusion admitted to Handan First Hospital, Hebei Province were retrospectively analyzed.All of them were dialysis patients with chronic renal failure.All patients underwent percutaneous balloon angioplasty via the cephalic vein.The success rate of technique, clinical success rate, perioperative complications and follow-up were observed.Results:(1) Technical success rate and clinical success rate: 90 patients were treated with percutaneous transluminal angioplasty (PTA) via the cephalic vein, the other 3 patients were treated with interventional therapy via the brachial artery, and 3 patients underwent reconstruction of internal fistula.The technical success rate was 93.8% (90/96), and the clinical success rate was 89.6% (86/96). (2) Perioperative complications: thrombosis in 4 cases, vasospasm in 3 cases.There were no serious complications such as vascular rupture, aneurysm, vascular dissection, and no perioperative death.(3) The first stage patency rate was 100% (90/90), 74.4% (67/90), 62.2% (56/90) and 46.7% (42/90) in 3, 6, 12 and 18 months after operation.Conclusion:Venipuncture can be used as the first choice for AVF stenosis interventional therapy because of its advantages of small trauma, no serious complications, no need of long-term compression at the puncture point, immediate dialysis, and avoidance of local hematoma and other complications caused by artery puncture.

Objective:To compare the clinical effect and perioperative complications of the treatment of autogenous arteriovenous fistula stenosis by arterial and venous approach.Methods:The clinical data of 120 patients with AVF stenosis and occlusion who were treated with interventional therapy and met the inclusion criteria were collected and analyzed by retrospective case-control study.from September 2017 to August 2018, 60 patients with internal fistula stenosis were treated by transarterial approach (arterial approach group), and from September 2018 to may 2019, 60 patients were treated with a new surgical scheme(venous approach group). The operation success rate, perioperative complications and patency rate of 3, 6, 12 months after operation were compared between the two groups.Results:(1) The technical success rate was 96.7% (58/60) and the clinical success rate was 91.7% (55/60) in the arterial approach group, and 95.0%(57/60) and 93.3%(56/60) in the venous approach group.There was no significant difference in the technical success rate and clinical success rate between the two groups ( P=0.718 and 1.000, respectively) (2) Perioperative complications: in the arterial approach group, 3 patients had hematoma at the puncture point, 2 pseudoaneurysms and 5 thrombosis.There were 3 patients with thrombosis in the venous access group, and the difference in the incidence of complications between the two groups was statistically significant (χ 2=4.227, P=0.036). (3)The primary patency rates at 3, 6 and 12 months after operation were 95.0%(57/60), 75.0%(45/60) and 60.0%(36/60) in the arterial approach group, and 96.7%(58/60), 71.7%(43/60) and 61.7%(37/60) in the venous access group, respectively.There was no statistically significant difference between the two groups ( P=0.718, 0.749, 0.885). Conclusion:The interventional treatment for autogenous arteriovenous fistula stenosis through artery and vein approach can achieve good effect.There were many complications during the perioperative period, It is suggested that venous approach is preferred.

Apoptosis inhibitor of macrophage(AIM)belongs to group B of the scavenger receptor cysteine rich-super family.AIM is a soluble protein secreted by macrophages.The expression of this protein is controlled by the liver X receptor.AIM,which is secreted by macrophages,plays important and broad roles in the immune responses of the body.It not only inhibits the apoptosis of macrophages but also participates in the regulation of macrophage polarization.In addition,studies have revealed that AIM is involved in various physiological and pathological processes,such as inflammation,obesity,atherosclerosis,and cancer.It has been used as a biological marker for the diagnosis of diseases such as tuberculosis and liver cirrhosis.Moreover,it can promote the lipolysis of adipose cells by inhibiting the activity of fatty acid synthase(FAS),playing an important role in the regulation of lipid homeostasis,lipid metabolism,and autoimmune diseases.In this paper,we review the multiple functional characteristics of AIM and its effects on inflammation,lipid metabolism,and related diseases to provide a theoretical basis for relevant medical research.

Objective To investigate the expression and significance of FBXW7 and ENO1 in ovarian serous adenocarcinoma of different grades. Methods Immunohistochemistry was used to study the expression of FBXW7 and ENO1 in 60 cases of ovarian serous adenocarcinoma. The relationship between FBXW7 and ENO1 proteins and the prognosis of ovarian serous adenocarcinoma was analyzed. Results The positive rate of FBXW7 expression was 22. 5％ ( 9/40) in 40 cases of ovarian high grade adenocarcinoma and 10 cases in 15 cases of normal oviduct. The positive rate of FBXW7 expression was 66. 7％ ( 10/15) ,and the difference was statistically significant ( P=0. 003) . The expression of FBXW7 in 20 cases of low grade adenocarcinoma was 5 cases,and the positive rate was 25. 0％( 5/20) . In 15 cases of normal ovarian tissue,9 cases were positive,and the positive rate was 60. 0％( 9/15) . The difference was statistically significant ( P=0. 04) . The expression of ENO1 protein was 27 in 40 cases of high grade adenocarcinoma,and the positive rate of expression was 67. 5％( 27/40) . 5 cases were positive in 15 normal fallopian tubes, and the positive rate was 33. 3％( 5/15 ) . The difference was statistically significant ( P = 0. 024 ) . The expression of ENO1 protein was 15 in 20 cases of low grade adenocarcinoma,and the positive rate of expression was 75. 0％( 15/20) . In 15 cases of normal ovarian tissue,4 cases were positive, and the positive rate was 26. 7％( 4/15 ) . The difference was statistically significant ( P=0. 006) . There was no correlation between the low expression of FBXW7 and the high expression of ENO1 in high grade ovarian adenocarcinoma ( P= 0. 199 ) , but there was a significant correlation between the low expression of FBXW7 and the high expression of ENO1 in low grade ovarian adenocarcinoma ( P<0. 05) . In low grade serous adenocarcinoma,the 5-year survival rates were 44. 4％ and 32. 1％ respectively,with no significant difference ( P = 0. 052 ) . In ovarian high-grade serous adenocarcinoma, the 5-year survival rates of high-expression group and low-expression group were 20. 0％ and 7. 7％, respectively, with no significant difference ( P=0. 097) . In low grade ovarian serous adenocarcinoma,the 5-year survival rate was 7. 4％ in high expression group and 50. 0％ in low expression group ( P=0. 023) . The 5-year survival rates of ENO1 in high-grade serous adenocarcinoma were 0％ and 40. 0％ in high-expression group and low-expression group respectively ( P=0. 001) . Conclusion The low expression of FBXW7 in ovarian adenocarcinoma suggests that FBXW7 may be a tumor suppressor gene in ovarian serous adenocarcinoma, and ENO1 may be an oncogene in ovarian adenocarcinoma. The high expression of FBXW7 in serous adenocarcinoma indicates that ENO1 may be an oncogene,and the survival rate of FBXW7 in serous adenocarcinoma is higher than that in low expression group. The survival rate of the high-expression group was lower than that of the low-expression group. Therefore, they may become a new diagnostic index and therapeutic target for ovarian serous adenocarcinoma.

Objective:To explore the regulatory effect of Suaeda salsa on renal apoprosis inhibitor of macrophage (AIM) and macrophage polarization in diabetes kidney disease (DKD) model rats.Methods:A DKD rat model was established using a high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin (STZ). The rats were divided into model group, metformin group, and Suaeda salsa high-, medium-, and low-dosage groups using a random number table method, with 8 mice in each group. The normal group was set with 8 rats in this group. The metformin group was given 85.71 mg/kg of metformin solution by gavage, while the Suaeda salsa high-, medium-, and low-dosage groups were given 3.08, 1.54, and 0.77 g/kg of Suaeda salsa suspension by gavage (raw dosage). The normal group and model group were given equal volumes of saline by gavage, once a day, administered by gavage for 12 weeks of intervention. Fasting blood glucose (FBG) and glucose tolerance (OGTT) were measured, and the area under the curve (AUC) was calculated; the levels of glycosylated hemoglobin (HbA1c) and glycosylated serum protein (GSP) were detected; urea nitrogen (BUN), serum creatinine (SCr), and 24-hour urine protein (24 hUP) were detected; HE staining was used to observe the pathological morphology of the kidneys; Masson and PAS staining were used to observe renal tissue fibrosis; Western blot method was used for detecting AIM, CD206, CD86, TNF-α and IL-10 protein levels in renal tissue; Immunofluorescence was used to detect the average optical density values of AIM, CD206, and CD86 proteins in renal tissue.Results:Compared with the model group, the FBG, OGTT AUC, HbA1c, GSP of each dosage group of Suaeda salsa decreased ( P<0.01); the expression levels of AIM, CD206, and IL-10 proteins in renal tissue increased ( P<0.01 or P<0.05), while the expression levels of CD86 and TNF-α protein significantly decreased ( P<0.01 or P<0.05); HE, Masson, and PAS staining results showed that compared with the model group, the changes in renal microvasculature and renal fibrosis of rats in each dosage group of Suaeda salsa were improved. Conclusion:Suaeda salsa may regulate AIM, promote polarization of M2 macrophages, improve the inflammatory microenvironment of macrophages, thereby lowering blood lipids of DKD rats, and improving renal pathological damage.

Objective:To explore the clinical effect of the simultaneous innervated "Bi-system bone flap" on preventing postoperative spontaneous resorption of the bone grafts and recovering lip sensation after reconstructing mandibular defects.Methods:Patients with segmental mandibular defects from the Department of Oral and Maxillofacial Head and Neck Oncology, Shanghai Ninth People’s Hospital were prospectively selected. Following the screening, they were randomly divided into an innervated group and a control group according to the random number table. When the free vascularized iliac bone flap was used to repair the mandibular defect, the ilioinguinal nerve was chosen to innervate a composite tissue flap containing one pedicle (deep circumflex iliac artery), double islands (an internal oblique muscle flap and an iliac bone flap) and one nerve (ilioinguinal nerve). We anastomosed the ilioinguinal nerve with the inferior alveolar nerve and the mental nerve in the innervated group. In the control group, no nerve was involved in the composite tissue flap which contained one pedicle (deep circumflex iliac artery) and double islands (internal oblique muscle flap and iliac bone flap). CT value(Hu) decrease rate, width and height of iliac bone flap 6 months after the operation were used to evaluate the postoperative resorption. The algesia examination, two-point discrimination test and current perception threshold (CPT) test of sensory nerves were used to evaluate the recovery of the lower lip sensation. P value less than 0.05 in independent-samples t test meant the statistically significant difference. Results:Eight patients between 17-38 years old were included with an averaged age of 29.5 years, and the range of mandibular defects was 5-9 cm. There were 4 cases in the innervated group and 4 cases in the control group. All the iliac bone flaps survived. The appearance was satisfactory, and no severe complications were found in the donor and recipient sites. In six-month follow-up, the CT value decrease rate of the bone grafts was (3.13±1.21)% in the innervated group, less than that (20.32±5.23)% in the control group, and the difference was statistically significant ( t=-6.401, P=0.006). Few changes of width and height of the bone grafts were found 6 months after surgery in both groups, and the difference was not statistically significant ( P>0.05). The sensation of the lower lip in the operation area was recovered in the innervated group to some extent, and no obvious pain was showed in the control group. In the two-point discrimination test, it was more than 20 mm in the affected side of the control group, while it was less than 20mm in the innervated group. In the healthy side of the two groups, it was less than 14 mm. The results of the quantitative sensory examination in affected lower lip by CPT test showed that two cases in the innervated group were mild sensory dysfunction, one slight sensory dysfunction and one moderate sensory dysfunction, while all cases in the innervated group were severe sensory dysfunction. The sensory dysfunction of the healthy side was milder than that of the affected side. Conclusions:The innervated "Bi-system" DCIA flap can prevent postoperative osteoporosis of the bone grafts and recover the sensation of the lower lip following mandibular reconstruction, improving the quality of mandibular defect reconstruction.
