Stage 4 of chronic kidney disease ( stage 4 CKD ) is induced by insufficiency of spleen and kidney , disorder of qi activity, poor circulation of blood and body fluid metabolic disorders. It is a disease due to the internal generation of dampness , turbid , stasis and toxin . Clinical observation has already demonstrated that in-sufficiency of spleen and kidney is the key pathogenesis and characteristics in stage 4 CKD . In this article , the necessity of regulating and nourishing spleen and kidney on stage 4 CKD was discussed from two aspects , which were the disease characteristics and the connotation of regulating and nourishing spleen and kidney . It provided brief and essential syndrome differentiation and treatment strategies in the clinical treatment of stage 4 CKD .

Chronic renal failure ( CRF ) , which is a progressive disease , is difficult to be reversed after the pathological damage was formed . Hence , a variety of integrated and complementary therapies should be used for the lifelong treatment and regulation . This article suggested that therapeutic methods should be given ac-cording to different stages of CRF in its development . Chinese medicine comprehensive therapy should be given to the early and middle stage chronic renal failure patients in order to delay the disease progression . In the uremia stage , replacement therapy should also be used as the basic treatment in order to reduce the general complications of dialysis or a kidney transplant , thereby improving the quality of life of patients . The integra-tion of Chinese medicine therapy on CRF are from three aspects , which are Chinese medicine decoction based on syndrome differentiation , Chinese medicine external therapy and Chinese medicine featured CRF management in order to receive better therapeutic effects .

Malignant tumors are highly heterogeneous in terms of molecular phenotypes such that personalized therapy will be-come the standard for tumor therapy. Molecular classifications of cancer based on differences in biological behavior are important for selecting treatment strategies and prognostication. The unique optical and chemical properties of quantum dots have been widely used in biomedical applications such as tumor diagnosis, monitoring, pathogenesis, treatment, molecular pathology, and heterogeneity based on biological markers. In this study, we discuss the application of quantum dot-based nanotechnology and the molecular classification of cancer in personalized oncology.

Objective To investigate the operative techniques for refractory cholelithiasis. Methods The clinical data of 521 patients with refractory cholelithiasis who had been admitted to People's Hospital of Hunan Province from January 1990 to December 2007 were retrospectively analyzed. Results All patients received surgery. After the operation, 3 patients died of liver and kidney failure, the remaining 518 patients were cured without severe complications. The results of B ultrasound and computed tomography showed residual stones in 78 patients (15.1%). Four hundred and twenty-three patients (81.7%) were followed up for 5 months to 17 years (mean, 7.5 years), and the rate of positive effect was 90.1% (381/423). Conclusions Most of the refractory cholelithiasis can be cured radically. Individualized surgical planning, fine and standard surgical procedure are key to the treatment effect.

Objective To investigate the safety and short-term effect of anatomical hepatectomy for the treatment of hepatolithiasis with the caudate lobe as the sole remnant liver.Methods The clinical data of 1 patient with hepatolithiasis combined with liver atrophy-hypertrophy syndrome who was admitted to the Hunan Provincial People's Hospital in April 2014 were retrospectively analyzed.The stones were located in the left and right liver, the involved liver became fibroatrophy, and the hepatic caudate lobe not containing stones became hypertrophy.The body surface area of the patient was 1.65 m2 , standard total liver volume was 1 167.63 mL.According to the result of CT, expected residual liver volume after hepatectomy was 706.12 mL, and the ratio of residual liver volume over the standard total liver was 60.47％.The radio of residual liver volume over the body mass index was 1.21％.The patient received the second exploration of common bile ducts, hepatectomy with the caudate lobe as the sole remnant liver and T tube drainage.The follow-up including recurrence of calculus was performed by outpatient examination and telephone interview up to April 2015.Results The patient underwent caudate lobe as the sole remnant liver following anatomical hepatectomy successfully without blood transfusion.The operation time and volume of intraoperative blood loss were 380 minutes and 350 mL.The peritoneal drainage tube was removed at postoperative day 2 and the patient was discharged at postoperative day 8 with a good recovery of liver function.The postoperative pathological examination showed that there were focal biliary epithelial papillary hyperplasia combined with light-medium atypical hyperplasia and no canceration.The T tube cholangiography two month later showed that there were unobstructed lower bile duct and no residual intra-and extra-hepatic stones.The liver function was normal.Then T tube was removed and patient resumed normal life.During the 1-year follow-up, no chills and fever, jaundice and abdominal pain occurred, no calculus was detected by B-ultrasonography, and computed tomography reexamination showed that remnant liver volume was increased and no intra-and extra-hepatic bile duct stones were detected.Conclusion Anatomical hepatectomy for the treatment of hepatolithiasis with the caudate lobe as the sole remnant liver is safe and feasible, with a good curative effect.

Objective:To study the feasibility, safety and technique for laparoscopic anatomical liver resection of segment 8.Methods:The clinical data of 9 patients who underwent laparoscopic anatomical liver resection of segment 8 from January 2015 to December 2019 at Hunan Provincial People's Hospital were retrospectively analyzed. There were 6 males and 3 females, with age ranging from 29 to 67 years (average 53.6 years). The operation time, intraoperative blood loss , postoperative hospital stay, postoperative complications, and long-term survival and recurrence rates on follow-up were analysed.Results:Laparoscopic anatomical liver resection of segment 8 was successfully carried out in these patients. The mean operative time was 188.9 min(range 140-240 min). The mean estimated intraoperative blood loss was 117.8 ml (range 20-300 ml). The postoperative hospital stay was 6.9 days (range 3-12 days). One patient developed pleural effusion after operation and responded to conservative treatment. Another patients developed ascites with delayed extubation. The patient was successfully treated with conservative treatment. No patients developed complications above Clavien Dindo Ⅲa. There were no perioperative deaths. The postoperative pathological results showed hepatocellular adenoma ( n=2), hepatocellular carcinoma ( n=4), cholangiocarcinoma ( n=1), and metastatic liver cancer ( n=2). On follow-up for 12-58 months (median 22 months) one patient with hepatocellular carcinoma developed recurrence at 18 months after operation and was treated with microwave ablation. The other patients were well on follow-up. Conclusions:With adequate preoperative evaluation, reasonable case selection, rigorous surgical planning, and skilled laparoscopic techniques, laparoscopic anatomical liver resection of segment 8 was safe and feasible, and the short-term efficacy was good in this study.

OBJECTIVETo study the relationship of TCM Syndromes, involving Viscera Syndrome and involving Meridian Syndrome, with blood hypercoagulative state and insulin resistance in patients with diabetic ischemic stroke.

METHODSInsulin sensitivity index (ISI) could reflect the insulin resistance, and those reflecting blood hypercoagulative state parameters such as platelet agglutination test (PAgT), fibrinogen (FG), in vitro thrombus length (VTL) and activating partial thrombinogen time (APTT), were used to expound and prove the relationship with the stroke syndrome.

RESULTSThe symptom scores, PAgT, VTL, FG levels in patients involved with Viscera Syndromes (including those of Wind Syndrome, Phlegm-Dampness Syndrome, Heat-Fire Syndrome and Yin-deficiency with Yang-excess Syndrome) were significantly higher than those in patients involved with Meridian Syndromes (P < 0.05 or P < 0.01), while the ISI level in the former was lower than that in the latter (P < 0.01).

CONCLUSIONThere is close relationship between blood hypercoagulative state, insulin resistance and TCM Stroke Syndromes in patients with diabetic ischemic stroke.
