Research progress on the correlation between aqueous humor components and pathogenesis and postoperative complications in patients with different types of cataracts

Aqueous humor provides the necessary nutrition for the lens and transports the metabolites in the eye.It was a liquid that can directly reflect the microenvironment in the eye'and it can be easily obtained during the operation.This review intended to analyze the components of aqueous humor in patients with different types of cataracts'so as to reflect the pathogenesis and development of the disease'evaluate the incidence of postoperative complications and provide reference value for the surgical design of sequential cataract surgery.The aqueous humor components of different types of cataracts showed different degrees of inflammation'oxidative stress and extracellular matrix remodeling.The biomarker of early neuropathy in diabetic cataract was neural cell adhesion molecule-1(NCAM1).Transforming growth factor-β(TGF-β)was the evaluation factor of disease development in patients with pseudoexfoliation syndrome.The relationships between postoperative complications of different types of cataracts and aqueous humor components were as follows:Macular edema after diabetic cataract surgery was associated with tumor necrosis factor-alpha;capsular contraction after high myopic cataract surgery was related to monocyte chemoattractant protein-1(MCP-1)and TGF-β2;Klotho and glutathione S-transferase P 1(GSTP1)were associated with high intraocular pressure after primary open-angle glaucoma complicated by cataract surgery;capsular contraction after retinitis pigmentosa complicated by cataract surgery was associated with matrix metalloproteinases;pro-inflammatory cytokines and fibroblast growth factor 4 in the aqueous humor of congenital cataracts were associated with posterior capsular opacification after surgery.Granulocyte colony stimulating factor 3 and MCP-1 were the main cytokines mediating the pain of the second eye in the binocular sequential cataract surgery short interval(1 wk)'while MCP-1 mediated pain in the long interval(6 wk).The second eye after binocular sequential cataract surgery had a higher level of proinflammatory factors.The components of aqueous humor in patients with different types of cataracts were related to the pathogenesis and postoperative complications of the disease.Monitoring the components of the aqueous humor could help better understand the intraocular microenvironment of different types of cataracts and provide a reference for predicting the development of the disease and implementing relevant targeted therapy.

Cranial ultrasound in perioperative period of acute severe traumatic brain injury

Objective To observe the value of cranial ultrasound for perioperative patients with acute severe traumatic brain injury(sTBI).Methods Data of 55 sTBI patients who underwent craniotomy were retrospectively analyzed.The patients were divided into observation group(n=15)and control group(n=40)according to received perioperative cranial ultrasound or not.The general data and surgical data were compared between groups,and ultrasonic data of observation group were analyzed.Results The proportions of good prognosis 1 and 6 months after operation in observation group were both higher than those in control group,while the incidence of cerebral infarction in observation group was lower than that in control group(all P<0.05).No significant difference of general data nor other surgical data was found between groups(all P>0.05).Acute encephalocele occurred in 1 case in observation group during operation,and cranial ultrasound accurately showed the contralateral secondary epidural hematoma.Increased intracranial pressure in different degrees were found in all 15 cases(15/15,100%)in observation group after operation with transcranial color coded Doppler(TCCD)or transcranial Doppler(TCD),while cerebral vascular spasm was observed in 5 cases(5/15,33.33%),among them 4 cases(4/5,80.00%)were diagnosed cerebral infarction based on CT examination.Conclusion Cranial ultrasound could be used to evaluate changes of sTBI in perioperative period and guide adjusting treatment strategy in time,being valuable for reducing risk of postoperative cerebral infarction and improving prognosis.

Comparative study on the efficacy of transoral robotic surgery and non-robotic surgery for tongue base tumors

Objective:To compare the efficacy of transoral robotic surgery(TORS)and non-robotic surgery(NRS)in the treatment of tongue base tumors.Methods:A total of 45 patients with tongue base tumors treated in our hospital were selected,and they were divided into the TORS group and NRS group according to different surgical methods.The surgical indicators and postoperative complications of patients in the two groups were compared and analyzed.Results:Compared with the NRS group,the operative time,bleeding volume and length of hospital stay were less in the TORS group,and the postoperative recurrence rate was less in the TORS group than that in the NRS group.The incidence rate of dysphagia and restricted mouth opening in the TORS group was lower than that in the NRS group within 30 d after surgery,and the difference was statistically significant(P<0.05).Conclusion:TORS has better minimally invasive advantages in the treatment of tongue base tumors,including less intraoperative bleeding,smaller trauma,shorter length of hospital stay and faster recovery.

Risk Factors of Early Complications after Pancreaticoduodenectomy in 200 Consecutive Patients

To study the risk factors for early complications after pancreaticoduodenectomy （PD）. Methods： Two hundred patients undergoing PD at our hospital between December 1996 and September 2002 were reviewed retrospectively. Standard PD was performed on 176 cases, standard PD with extended lymphadenectomy on 24 patients, whereas pylorus-preserving PD was not used. An end-toside combined with mucosa-to-mucosa pancreaticojejunostomy was performed on the patients with a hard pancreas and a dilated pancreatic duct, and a traditional end-to-end invagination pancreaticojejunostomy on the patients with a soft pancreas and a non-dilated duct. The risk factors with the potential to affect the incidence of complications were analyzed with SAS 8.12 software. Logistic regression was then used to determine the effect of multiple factors on early complications. Results： The overall rate of the major com- plications was 21% （42/200）, with the failure of pancreaticojejunal anastomosis being the most frequently encountered. Age （odds ratio [OR] 2.162）, diabetes mellitus （OR 4.086）, total serum bilirubin level （OR 7.556）, end-to-end pancreaticojejunostomy （OR 2.616）, T tube through the choledochojejunostomy （OR 0.100）, and blood transfusion over 1000 mL （OR 2.410） were the significant risk factors for the morbidity. Conclusion： The results from published series concerning morbidity after pancreaticoduodenectomy are not comparable because of lack of homogeneity between them. The knowledge of the complications rate in each particular department turns out essentially to provide the patient with tailored information about risks before surgery. Additionally, management of postoperative complications is essential for improving the results of this operation.

Clinical Application of Exclusive Right-Thoracic Approach in Surgery with or without Laparotomy for Mid-Upper Esophageal Cancer

OBJECTIVE To evaluate the clinical application of a right-thoracic approach with or without laparotomy for mid-upper esophageal cancer. METHODS We retrospectively reviewed the data of 34 esophageal cancer patients who received Belsey surgery or a modified Ivor-Lewis surgery from November 1992 to April 2007. Twenty of the patients underwent a Belsey prodecdure （Group A） from November 1992 to January 2001 and 14 underwent a modified Ivor-Lewis prodecdure （Group B） from May 2001 to April 2007. RESULTS Twenty patients with esophageal cancer received an esophagectomy through an exclusive right-thoracic approach （Belsey surgery）, and 14 patients received an esophagectomy through a right-thoracic approach combined with a laparotomy （modified IvorLewis surgery）. The complication rate was 15% （3/20） and 7.1% （1/14） respectively. The survival rate was 42.9% （5-year survival） and 38.7% （5-year survival） respectively for these two groups. CONCLUSION An exclusive right-thoracic approach （Belsey surgery） is associated with more complications. It is not a routine surgery for cancer of the mid-upper thorax of the esophagus, but can be selectively used as palliative esophagectomy for esophageal cancer patients with poor pulmonary function. Modified Ivor-Lewis surgery can simultaneously be utilized to resect the primary tumor and dissect lymph nodes of the thorax and abdomen. With a shorter time period of surgery and postoperative recovery period, modified Ivor-Lewis surgery can achieve better effects with patients who have midupper esophagus cancer.

Diagnosis and Treatment of Liver Cystadenocarcinoma:Report of 18 Cases

Objective： To discuss the diagnosis and treatment of liver cystadenocarcinoma. Methods： The clinical, imaging, and pathological data of 18 patients with liver cystadenocarcinoma between January 2000 and December 2004 in our hospital were retrospectively analyzed. Results： The liver cystadeno- carcinoma was seen in males and females （m/f： 9/9）; mean age was 51 years. Ultrasonography revealed cystic parenchymatous mass echoes of fluid predominance with uneven margins. Nonenhanced CT revealed intrahepatic low-density space occupying shadows with nodular protrusions on the margins in all cases. Enhancement CT revealed that part of the nodular protrusions and tissues around the lesions were enhanced and the delayed phase disappeared. 66.67% （12/18） of the lesions were more than 10 cm in diameter. The diagnosis of liver cystadenocarcinoma was confirmed by postoperative pathology in all cases. Of these patients, 12 lesions were in the left lobe, 3 in the right lobe, 1 in the mid lobe, 1 in the right and left lobe, and 1 in the caudate lobe. Of tile 18 patients, 6 had completely resect the cystadenocarcinoma, 2 were surgically explored, one received TAE＋fine needle aspiration cytology＋injection of chemotherapy drugs, and 9 underwent radical hepatectomy＋choledochostomy or T-tube drainage, in which, one patient underwent choledochostomy＋left hepatectomy＋radical gastrectomy for cancer＋lymphadenectomy; one patient underwent resection of the cystadenocarcinoma, who had relapse 20 months after the initial procedure. The patient received repeat reseet for the recurrent cystadenoeareinoma＋eholangio-jejunostomy. Six months later she had another relapse and received repeat reseet （only PMCT） for the recurrent cystadenoearcinoma. The patient died from eholangiopleural fistula after third time operation （PMCT） was attempted perioperatively. Seven patients died of metastatic disease after operation. The remaining 10 patients were alive without cancer recurrence or metastasis （mean follow-up 20 months）. Conclusion： Liver eystadenocarcinoma is rarely seen and grows slowly. It shows some typical clinical and imaging features. The crux for diagnosing and treating liver cystadenoeareinoma is how familiar the surgeon is with the pathology and clinical features of the condition. Prolonged survival can be achieved by radical resection of the tumor.

Novel operating theatre scheduling method based on estimation of distribution algorithm

In order to improve the efficiency of operating rooms,reduce the costs for hospitals and improve the level of service qualities, a scheduling method was developed based on an estimation of distribution algorithm（ EDA）. First, a scheduling problem domain is described. Based on assignment constraints and resource capacity constraints, the mathematical programming models are set up with an objective function to minimize the system makespan. On the basis of the descriptions mentioned above, a solution policy of generating feasible scheduling solutions is established. Combined with the specific constraints of operating theatres, the EDA-based algorithm is put forward to solve scheduling problems. Finally, simulation experiments are designed to evaluate the scheduling method. The orthogonal table is chosen to determine the parameters in the proposed method. Then the genetic algorithm and the particle swarm optimization algorithm are chosen for comparison with the EDA-based algorithm, and the results indicate that the proposed method can decrease the makespan of the surgical system regardless of the size of operations. Moreover, the computation time of the EDA-based algorithm is only approximately 5 s when solving the large scale problems, which means that the proposed algorithm is suitable for carrying out an on-line scheduling optimization of the patients.

The Diagnosis and Treatment of Virilizing and Fem- inizing Adrenal Syndrome

Objective: To inquire into diagnosis, and treatment of virilizing andfeminizing a-drenal syndrome, differential diagnosis between benign and malignant sex hormoneproducing adrenal neo-plasma and, treatment principles of congenital adrenal hyperplasia (CAH).Methods: Eight cases of CAH and 5 cases of sex hormone producing adrenal neoplasma were admitted tohospital during 1986-1996. The former included 3 rare cases of 17 a hydroxylase deficiency. Thelatter included 3 cases of feminizing adrenal tumor and 2 cases of virilizing adrenal tumor.Results: Weight, size and CT of the tumor, DHEA, 17 -ks, sex hormone levels, infiltration, andmetastasis were closely related to the degree of differentiation of the tumors. Conclusion:Virilizing and feminizing adrenal neoplasm were removed surgically by different incisions. Modifiedsubcostal incision was recommended as the best choice for huge adrenal mass. Corticoadrenal hormonetreatment fa CAH should be individualized according to the different types of the disease. Sexhormones were not suitable for children suffering from 17 hydroxylase deficiency before puberty.

An Analysis of Prospective Outcome of Re-resection for Recurrent Live Cancer and Extrahepatic Metastases,a Follow-up of 267\Cass

Objective To evaluate the prospective outcome and summarize experience in re-resection for recurrent liver cancer and extrahepatic metastases. Methods The clinical data of 267 patients with recurrent primary liver cancer (PLC) after re-resection from January 1960 to July 2000 were retrospectively analyzed. Re-hepatectomy was performed on 205 cases, resection of extrahepatic metastases on 51 cases and combined resection of recurrent liver cancer and extrahepatic metastases on 11 cases. The clinico-pathologic features, operation type and survival were compared. Results The types of liver re-resection included left lateral lobectomy in 11.2% of patients, hemihepatetomy and extended hemi-hepatectomy in 4.4%, local radical resection in 68.3%, other subsegmentectomy in 17.1%. The peak recurrence rate (64.4%) occurred at 1–2 years. The overall 1-, 3, 5- and 10-year survival rates after second resection were 81.0%, 40.3%, 19.4% and 9.0% respectively, while they were 77.5%, 29.8%, 13.2% and 6.61% respectively after the third resection. The median survival time was 44 months. The re-resection with extrahepatic metastases also provided the possibility of longer survival. Conclusion The results suggest that subsegmentectomy and local excision is appropriate for the hepatic repeat resection. The peak recurrence may be correlated with portal thrombus and operative factor. The re-resection can be indicated not only in intrahepatic recurrent metastases but also in extrahepatic metastases in selected patients. Re-resection has become the treatment of choice for recurrence of PLC, as neither chemotherapy nor other nonsurgical therapies can achieve such favorable results. Key words prospective outcome - re-resection - primary liver cancer - recurrence - extrahepatic metastases
