OBJECTIVE: To investigate the effects of Yangyin Shengjin Decoction (YYSJD) on hemorheological parameters and coagulation factors in model rabbits with syndrome of excessive heat consuming body fluid and blood stasis. METHODS: Rabbit model with syndrome of excessive heat consuming body fluid and blood stasis was produced. The effects of YYSJD on the blood viscosity, erythrocyte sedimentation rate (ESR), hematocrit, platelet aggregation rate, prothrombin time (PT), thrombin time (TT), kaolin partial thromboplastin time (KPTT), fibrinogen (Fg), thromboxane B(2) (TXB(2)), and 6-keto-prostaglandin F(1alpha) (6-keto-PGF(1alpha)) in the model rabbits were observed. RESULTS: YYSJD decreased the whole blood viscosity and hematocrit, inhibited the platelet aggregation, prolonged PT, TT and KPTT, and reduced the content of Fg. It also regulated the balance between TXB(2) and 6-keto-PGF(1alpha). CONCLUSION: YYSJD can promote the blood circulation, adjust the blood agglutinating function, and decrease the formation of thrombus. This is one of the pharmacological mechanisms of the therapeutic method of "nourishing yin to promote blood circulation" in the theory of traditional Chinese medicine for seasonal febrile diseases.

Objectives: To evaluate the effect of TPN plus argine on nutrition status, immune function and postoperative complications in radical treatment of gastro intestinal cancer patients. Methods: 88 cases undertaking radical treatment were randomized into TPN group (normal group)(30 cases), argine group (plus argine)(30 cases) and control group (28 cases). Since POD+1, the former two groups were given intravenous nutrition support continuously for 7 days and argine 80～100ml/day in argine group.Controlled group was given glucose, amino acid solution and electrolytes first, then transited to normal oral food intake. On AOD-1 and POD+8, albumin, pre albumin, transferrin and immune parameters were analyzed; postoperative complications were observed as well. Results: On POD+8, pre albumin and transferrin were improved in normal and argine group. In argine group, IgG?IgE?CD3?CD4?CD4/CD8?NKC activity and IL 2 concentration were obviously higher than that in other two groups( P

Objective To study the therapeutic effect of rheum(Chinese herbal medicine) preparation made by using ultrasonic technique on pro-inflammatory cytokines and sepsis in rats.In order to offer novel measure for the treatment of critically ill patients.Methods Firstly, rheum sterile solution was prepared through ultrasonic technique.Secondly, fifty healthy male SD rats were randomly(random number) divided to CLP group and rheum group.Moderate degree of sepsis model was established by using cecal ligation and puncture(CLP).Rats in group rheum received the liquid rheumpreparation via intragastric administration, while rats in group CLP received saline instead.The 7-day survival rate was recorded and was compared between two groups.In addition, another fifty-four rats were randomly(random number) divided to sham group, CLP group and rheum group(n=18 in each group).CLP was performed to induce sepsis in CLP group and rheum group.Then rats in rheum group received rheum sterile solution via intragastric administration, while rats in CLP group received saline instead.At 12 hours, 24 hours and 48 hours after modeling, six rats in each group were randomly sacrificed.Serum TNF-α and HMGB1 levels were detected by ELISA method.Levels of RAGE, HMGB1 and NF-κB P65 in small intestine were detected by Western Blot.Results Level of anthraquinones extracted from rheum by ultrasonic technique was higher than that by conwentional decoction method.The 7-day survival rate of rats in rheum group(76%) was higher than that in CLP group(48%)(P<0.05).Compared with sham group, serum TNF-αand HMGB1 levels in CLP group and rheum group were significantly increased(P<0.05).TNF-α was significantly lower in rheum group than that in CLP group at each interval(P<0.05).At 12 hours after modeling, there was no significant difference in serum HMGB1 level between CLP group and rheum group(P>0.05).At 24 hours and 48 hours after modeling, serum HMGB1 levels were significantly lower in rheum group than those in CLP group(P<0.05).Compared with sham group, protein levels of HMGB1, RAGE and NF-κB in small intestine were elevated in CLP group and rheum group at 48 hours after modeling(P<0.01), while protein levels of above biomarker were higher in CLP group than those in rheum group(P<0.05).Conclusions Rheum sterile solution could down-regulate the level of pro-inflammatory cytokines, modulate the inflammatory response, and improve the survival rate in rats with sepsis.

Objective To study the molecular mechanism of Bel subtype caused by mutation p.R168W of glycosyltransferase B.Methods Serological test,SSP-PCR and direct sequence the Exon6 and Exon 7 of the ABO gene.Construct a 3D molecular model and predict the structural impact of GTB protein mutations.Results A antigen or B antigen can't be detected on the surface of the propositus' RBC,and only anti-A antibodies were detected in her serum.But serological test indicated her daughter's blood type was a normal B type.SSP-PCR test indicated propositus' ABO gene type is O1 B.By gene sequencing the Exon 6 and Exon 7 of the ABO gene,a ABO Bel allel(c.502C＞T,p.R168W)was discoverd in both the propositus and her daughter.Through the propositus' daughter coexisted Bel gene with normal B gene,her blood type was a normal B type.Conclusions ABO gene c.502C＞T mutations cause Bel phenotypes in patients by reducing the stability of GTB.

Objective To explore the expression of Tau protein in brains of the intractable epilepsy patients and discuss its function in the pathogenesis. Methods Immunohistochemistry was adapted to test the expression of Tau protein and the mossy fiber sprouting in the hippocampus and cortex of temporal lobe from 48 intractable epilepsy patients and age-mached 48 cases of controls. Results The expression of phosphorylated Tau protein in the CA_3 areas (0.0450?0.0115) and the molecular layers of dentate gyrus (0.0463?0.0120) in intractable epilepsy patients was increased, accompanied by the hippocampus mossy fiber sprouting (3.18?0.35). No difference on the expression of total Tau protein was observed between the intractable epilepsy patients and the controls. Conclusion The present findings demonstrate that the strengthening of phosphorylated Tau protein might play an important role for the synaptic reorganization of the hippocampus. Thus, the changes of phosphorylated Tau protein could improve clinical prognosis in the intractable epilepsy patients.

Objective: To improve the current understanding on the imaging features of pancreatic schwannoma. Methods: Clinical data of pancreatic schwannoma patients admitted in Changhai Hospital affiliated with Navy Medical University from January 1989 to January 2019 were retrospectively analyzed, related literature on pancreatic schwannomas was retrieved through the Chinese and English database, and clinical and imaging features of pancreatic schwannoma were analyzed. Results: A total of 84 cases were analyzed, including 3 cases of pancreatic schwannomas in Changhai hospital, and 81 cases reported in the literature. The age of onset was 17-78 years old, with an average of 55 years. There were 30 males and 54 females. The main symptoms were abdominal pain or the detection of pancreatic mass via body check. Pancreatic schwannoma was mainly in pancreatic head, and the lesion has a long diameter of 1-18 cm with an average of 4.6 cm, which can be solid, cystic (most frequent) and cystic-solid. The border of the lesion from the normal tissue was clear, and semi-transparent capsule composed of neural external membrane and fiber were often found. 15 patients underwent endoscopic ultrasonography guided fine needle aspiration, and diagnostic accuracy was 73.3%(11/15). No typical findings for pancreatic schwannoma was detected on CT. MRI was performed in 35 cases, and 12 cases had complete data. The characteristics of target sign were tumor tissue in completely low signal at T₁WI, and in partially low signal and partially high signal at T₂WI, and completely opposite signal characteristics of T₂WI area after T₁ enhancement, referring to the finding that low T₂WI signal part was gradually enhanced to be high signal, but high signal part was not enhanced and in low signal. Conclusions Pancreatic schwannoma is rare, and its target signs by MRI have imaging features which can help to improve the preoperative diagnosis.

BACKGROUNDSleeve recestion for lung cancer can get similar tumor and lymph node resection rate as pneumonectomy, with less influence on pulmonary function and much improvement of quality of life. The aim of this study is to compare the 5-year survival and complications of sleeve resection and pneumonectomy for lung cancer.

METHODSSurvival analysis was used to investigate the 5-year survival of 173 patients undergoing sleeve resection and 435 patients undergoing pneumonectomy from January 1990 to December 2000. Their complication and perioperative motality were also analyzed.

RESULTSThe overall 5-year survival for sleeve resection and pneumonectomy was 42.3% and 30.9%, respectively (P=0.007). 5-year survival of right lung sleeve resection was better than that of left lung [P=0.004 (N0), 0.025 (N1), 0.042 (N2)]. In left lung cancer patients without nodal involvement, the survival after sleeve resection was better than that after pneumonectomy. There was no survival difference between N1 and N2 lung cancer patients. Survival was not significantly different for bronchoplasty and pulmonary arterioplasty and pneumonectomy. The incidence rate of pneumonia and arrhythmia for sleeve resection was less than those for pneumonectomy (P=0.0019), and no significant difference of mortality was observed between the two groups.

CONCLUSIONSIn lung cancer patients suitable for sleeve resection or pneumonectomy, sleeve resection should be performed for right lung cancer and left lung cancer of stage I. Bronchoplasty and pulmonary arterioplasty don't prolong the survival of lung cancer patients compared with pneumonectomy.
