Central serous chorioretinopathy(CSC), the first described pachychoroid disease, is characterized by visual distortions and loss of vision, which are commonly seen in middle-aged male. Research has demonstrated that ocular blood flow in CSC is in a state of overload, characterized by the dilation of vortex vein ampullae and choroidal vasculature. The obstruction of venous outflow is linked to scleral thickness, while the choriocapillaris exhibits perfusion deficits due to compression from the engorged vascular layer. Over time, vascular remodeling occurs, with venous anastomoses forming to create alternative drainage pathways and mitigate blood stasis. These abnormalities in vortex vein dynamics and choroidal circulation play a critical role in elucidating the underlying pathogenesis and clinical manifestations of CSC. This review highlights the alterations in vortex vein and choroidal vasculature in CSC, hoping to understand how the changes of blood flow affect the course of CSC and their correlation with treatment response. By evaluating blood flow dynamics, we aim to determine the disease stage more accurately, optimize therapeutic strategies, and ultimately enhance patient outcomes.

Objective:To investigate the effect of endoscopic thyroidectomy through breast milk approach in patients with papillary thyroid carcinoma and its influence on Wnt and integrin signaling pathways.Methods:A total of 136 patients diagnosed with papillary thyroid carcinoma in our hospital from Jul. 2018 to Mar. 2020 were selected and were hospitalized for surgical treatment. According to different surgical procedures, they were divided into a study group (68 cases) and a control group (68 cases) . The control group was treated with open thyroidectomy and the study group was treated with thoracoscopic thyroidectomy. The two groups were compared in terms of immune function [CD4+, CD8+ and CD4+/CD8+], and pain index [PGE2, IL-6, Cor and VAS score]. RT-PCR method was used to detect WNT1, β-catenin, GSK3β and integrin Signal pathway before and after surgery.Results:Three days after operation, compared with the control group, the study group had significantly higher CD4+ and CD4+/CD8+ levels [ (27.62±2.52) vs (24.63±2.67) , (0.66±0.18) vs (0.52±0.13) ], while the CD8+ level was significantly lower [ (41.62±3.54) vs (45.62±3.63) ] ( P<0.001) ; PGE2, IL-6, Cor, VAS of the study group were significantly lower than the control group [ (48.54±9.86) vs (57.21±8.12) , (5.13±0.71) vs (6.99±0.95) , (511.23±67.52) vs (633.12±71.47) , (1.26±0.56) vs (3.99±2.06) ] ( P<0.001) ; WNT1, β-catenin, GSK3β, integrin β1, FAK, Ras, and MAPK mRNA expression levels in the study group were significantly lower than those of the control group[ (1.79±0.15) vs (2.85±0.25) , (1.94±0.15) vs (2.64±0.24) , (2.13±0.19) vs (2.97±0.28) , (1.95±0.17) vs (2.58± 0.23) , (2.15±0.16) vs (2.87±0.22) , (1.95±0.18) vs (2.91±0.27) , (1.89±0.12) vs (2.87±0.31) ] ( P<0.001) . Conclusion:Endoscopic thyroidectomy through thoracolumbar approach can effectively reduce postoperative pain in patients with papillary thyroid cancer, have a smaller impact on immune function, and block the expression of Wnt and integrin signaling pathways to reduce tumor metastasis risk.

Objective:To explore the necessity of transitional ICU care for patients with liver cancer after major hepatectomy.Methods:The clinical data of 548 liver cancer patients with major hepatectomy were retrospectively analyzed. According to whether by way of transitional ICU care was used or not, patients were divided into ICU group(92 cases) and none-ICU group(456 cases). The clinical data, postoperative complications and mortality were compared.Results:There were no difference in the incidence of major complications(ascites, liver failure, bile leakage, infection and bleeding), mortality and length of hospital stay between the two groups( P>0.05). But the total hospitalization costs of patients in the ICU group were significantly higher than those in the non-ICU group [(72 019±24 516) yuan vs. (67 002±21 374) yuan, t=2.004, P=0.046]. Multivariate analysis showed that intraoperative blood loss and transfusion were independent risk factors for patients undergoing transitional ICU care. Conclusion:Transitional ICU care does not reduce the incidence of postoperative complications and mortality for major hepatectomy patients, only increase the hospitalization costs.

Objective:To evaluate liver quadrate lobectomy combined with large-bore cholangio-jejunostomy for the treatment of benign biliary-enteric anastomotic stricture.Methods:The clinical data of 32 patients undergoing liver quadrate lobectomy combined with large-caliber cholangio-jejunostomy were retrospectively analyzed. The bile drainage effect and postoperative complications were analyzed. And the clinical effects of different size of biliary-enteric anastomosis were compared.Results:The most common short-term complications were cholangitis (9.4%) and bile leakage (9.4%), and the most common long-term complications were reflux cholangitis (15.6%). No anastomotic restenosis, stone formation or canceration were found. During the follow-up period, the total bilirubin ( t=19.455, P=0.000), direct bilirubin ( t=18.479, P=0.000), alkaline phosphatase ( t=3.229, P=0.002) and γ-glutamyltranspeptidase ( t=3.057, P=0.003) level were significantly improved. The effect of bile drainage in patients with 2-3 cm diameter of biliary-enteric anastomosis was similar to that in patients with >3 cm diameter ( t=0.284, P=0.778). The incidences of cholangitis (χ 2=0.121, P=0.728), bile leakage (χ 2=0.121, P=0.728) and reflux cholangitis (χ 2=0.205, P=0.652) were no statistical difference in both groups. Conclusion:Liver quadrate lobectomy combined with large-caliber cholangio-jejunostomy is effective in the treatment of benign biliary-enteric anastomotic stricture. More than 2cm in diameter of the biliary-enteric anastomosis is enough.

Objective:To investigate the effects of ulinastatin on liver function in patients with liver cancer after major hepatectomy.Methods:The clinical data of 232 patients with major liver resection due to liver cancer were retrospectively analyzed. According to whether ulinastatin was applied after operation, patients were divided into treatment group (105 cases) and control group (127 cases). The postoperative inflammatory factors, liver function, postoperative complications and hospital stay were compared.Results:The levels of CRP、IL-6 and TBIL、ALT、AST were significantly lower than the control group 3 days after surgery (CRP: t=4.520, P=0.000; IL-6: t=17.982, P=0.000; TBIL: t=9.843, P=0.000; ALT: t=11.913, P=0.000; AST: t=4.520, P=0.000). The incidence of massive ascites in the treatment group (χ 2=4.212, P=0.040) and the average postoperative hospital stay ( t=9.994, P=0.000) were significantly lower than that in the control group. Conclusion:Early application of ulinastatin effectively inhibits the inflammatory process, protects liver function, reduces the incidence of massive ascites, and shortens the postoperative hospital stay.

OBJECTIVETo optimize a compound prescription for treatment of liver fibrosis with an improved therapeutic effect and low toxicity.

METHODSIn rat models of liver fibrosis induced by thioacetamide (TAA), the optimized prescription was screened based on a uniform design with 2-factor 5-level table using Uniform Design 3.0 software and tested using liver content of Hyp as the screening index. To verify the efficacy of the optimized prescription, the rat models of liver fibrosis were randomized into normal control group, model group, colchicine group and optimized prescription group, and the changes of hepatic Hyp content, serum HA, ALT, AST, and ALB levels, and the pathology liver fibrosis were observed after corresponding treatments.

RESULTSThe optimized prescription, which contained 70 mg/kg glycyrrhizin and 70 mg/kg matrine, showed a significant therapeutic effect against liver fibrosis in rats (Plt;0.05), and the effect was equivalent to that of colchicine (P>0.05).

CONCLUSIONUniform design is a valuable method in prescription optimization. The optimized compound prescription of matrine and glycyrrhizin has a significant effect in inhibiting liver fibrosis.

Objective To summarize the experience in the diagnosis and treatment of hepatic trauma. Methods The clinical data of 260 patients with hepatic trauma admitted from January 1988 to December 2007 were retrospectively reviewed with regard to degree of trauma, treatment methods, therapeutical effects, complications and SO on. Results One hundred and fifty-three eases were treated by operative management,1 07 cases by nonoperative management.236 cases were cured,24 cases died,and the case fatality rate was 10.2%.There were no death among 139 patients with hepatic trauma grades Ⅰ～Ⅱ,22 death among 119 grades Ⅲ～Ⅴ patients, all death of 2 in grade VI, which demonstrated the correlation between death and hepatic trauma grade was statistically significant. Complications appeared in 82 eases, mainly including Secondary hemorrhage, abdominal infection and so on. Conclusions Nonoperative management is suitable for hepatic trauma with stable hemodynamics. Operative management is rapidly selected when the hemodynamics aren't stable. The cooperation of many specialities can enlarge the application of nonoperative management and decrease complications.

Objective To study the management of vascular injury.Methods Retrospective analysis was made on the clinical data of 59 cases of vascular injury,including 55 cases of vascular injury in neck and(extremity) and 4 cases of portal vein and vena cava injury.Among them,21 cases had femoral artery injury with infection and 4 cases had vascular injury due to intervention therapy.All patients with vascular wound of extremity or neck had undergone hemostasis by compression and antishock treament before hospital admission.All cases of femoral artery injury with infection underwent hemostasis by arterial ligation and incision and(drainage) of abscess.Vascular anastomosis was performed in 11 cases,vascular grafting in 12 cases,and(vascular) repair in 14 cases.Results There were 2 deaths.5 cases had amputation(including a case of(femoral) embolism due to intervention trerapy).Postoperative intermittent claudication,decreased skin(temperature) and other signs of ischemia occurred in 21 cases of femoral artery injury with infection,but none developed limb gangrene. The other cases were discharged in good health.Conclusions In the treatment of vascular injury,wound hemostasis and antishock treatment should be done first to save the patient′s life and the management of the vascular injury depends on the situation,with the aim to try by all means to save the extremity.Vascular reconstruction is the main method for treatment of vassular injury.Vascular ligation can be done in cases of femoral artery injury with infection.
