Objective To compare the efficacy of dexmedetomidine versus remifentanil in combination with sevoflurane for gynecological laparoscopy. Methods Forty ASA Ⅰ or Ⅱ patients aged 18-64 yr with body mass index of 18-30 kg/m2 undergoing gynecological laparoscopy were randomly assigned to one of two groups ( n =20 each): dexmedetomidine group (group D) and remifentanil group (group R). Starting from 5 min before induction of anesthesia, dexmedetomidine was infused at 0.05 μg · kg - 1 · min- 1 in group D and remifentanil at 0.1 μg· kg- 1· min-1 in group R for 10 min, then dexmedetomidine infusion rate was increased to 0. 3 μg· kg-1 · h-1 and remifentanil infusion rate was increased to 0.15 μg· kg-1 · min-1 . Anesthesia was induced with propofol 1.5-2.0 mg/kg and fentanyl 2 μg/kg. Tracheal intubation was facilitated with cis-atracurium 0.15 mg/kg. Anesthesia was maintained with sevoflurane and fentanyl 1 μg/kg and intermittent iv boluses of cis-atracurium. Narcotrend index was maintained at 40-50. Blood sample was taken from external jugular vein for blood gas analysis and determination of serum concentrations of corticosteroid, norepinephrine and epinephrine before administration, at 5 min after intubation, at 10 min of aeroperitoneum and at 5 min after extubation. The pH value and concentrations of lactic acid and glucose were recorded. The time for recovery of spontaneous breathing, eye-opening time, extubation time, orientation time and perioperative side-effects were recorded. Numeric rating scale was used to assess the intensity of pain during 2 h after operation. The analgesics used were also recorded. Results The serum concentrations of norepinephrine and epinephrine were significanfly lower at 10 min of aeroperitoneum, the time for recovery of spontaneous breathing was shorter, eye-opening time longer and the incidence of shivering and nausea and vomiting lower, the percentage of patients requiring rescue opioids lower in group D than in group R ( P ＜ 0.05). Conclusion The efficacy of dexmedetomidine combined with sevoflurane anesthesia is better than remifentanil combined with sevoflurane anesthesia for gynecological laparoscopy.

Syndrome, a very important concept in traditional Chinese medicine (TCM), is the essence and characteristics of TCM theory. Progress of related studies on syndrome will drive the development of TCM. Therefore, clinical and basic researches on syndrome have focused on the hotspot of TCM. In recent 60 years, many scholars have discussed the concept, essence and the establishment of standardization of syndrome from different angles and layers. Although many results have been obtained, there is still a certain one sidedness and dispute. Therefore, looking for a new theoretical tool to reveal the scientific connotation of TCM syndrome is imperative. TCM syndrome and biological entropy belong to two different subject concepts, but can also reveal the physiological and pathological state in the changes of life body growth. This article discussed isomorphism of TCM syndrome and biological entropy from the concept, theoretical background and characteristics, with a purpose to provide certain guiding significance to study and promote standardized researches on TCM syndrome.

Objective:The present study was aimed to evaluate the nutritional risk using nutritional risk screening 2002 (NRS2002) score and to investigate the impact of nutrition support on clinical outcome in hospitalized patients.Methods:Six hundred and ninety four hospitalized patients were recruited.NRS 2002 was applied to evaluate the nutritional risk of patients.Meanwhile,the effect of nutrition support on complication rate was evaluated between different types of patients.Results:14.0％ of patients had malnutrition and the incidence of nutritional risk was 27.5％.Patients with nutritional risk had a higher complication rate (P ＜0.01).Totally,22.0％ (153/694) patients received nutrition support,including 81.7％ patients with nutritional risk and 18.3％ patients without nutritional risk.Patients with nutritional risk benefited from nutrition support,as shown by lower complication rate and shorter length of hospital stay.In patients with nutritional risk,complication rate was lower in enteral fed patients compared to parenteral fed patients.Conclusion:With nutritional risk screening,patients' nutritional status can be evaluated and appropriate nutrition support can be performed.Compared to those without nutritional risk,patients with nutritional risk will benefit more from nutrition support,as indicated by lower complication rate and reduced length of hospital stay.

Objective: To detect potential mutations of the coagulation factor Ⅶ (F7) gene in a pedigree affected with hereditary FⅦ deficiency and explore its molecular pathogenesis. Methods: The FⅦ antigen (FⅦ∶Ag) was analyzed by an enzyme-linked immunosorbent assay (ELISA) method. Prothrombin time (PT), FⅦ activity (FⅦ∶C) and other coagulant parameters were quantified with an one-stage clotting assay. The F7 gene was amplified by PCR and sequenced. Mutational sites were confirmed by reverse sequencing. Impact of amino acid substitution was assessed using SIFT and PolyPhen-2 software. Structure of the mutant protein was analyzed using Swiss-pdb Viewer software based on the three-dimensional structure in the Protein Data Bank. Results: The propositus had prolonged PT (36.3 s), with FⅦ∶C and FⅦ∶Ag significantly reduced to 2% and 44%, respectively. Her father, mother, younger sister and daughter had slightly prolonged PT and reduced FⅦ∶C (86%-120%). The FⅦ∶Ag of her father and younger sister were also reduced. DNA sequencing revealed that the propositus has carried compound heterozygous mutations (Lys341Glu and IVS6-1G>A) of the F7 gene. Her father and younger sister were heterozygous for the IVS6-1G>A mutation, while her mother and daughter were heterozygous for the Lys341Glu mutation. Bioinformatics analysis indicated that Lys341Glu mutation may affect the stability and function of the FⅦ protein. Conclusion The Lys341Glu and IVS6-1G>A mutations probably underlie the reduced activity of FⅦ in this pedigree.

Objective To discuss the anticoagulation effects and safety of sodium citrate in continuous renal replacement therapy (CRRT).Methods A total of 140 cases who underwent CRRT in the intensive care unit (ICU) of Zhejiang Provincial People′s Hospital from January 2014 to December 2016 were selected as research objects and divided into the heparin sodium group (n=56),the low molecular weight heparin calcium group (n=48) and the sodium citrate group (n=36) according to the anticoagulation methods. The differences of anticoagulation effects,the average service life of the pipelines,the overall pipeline quantity,the total cost of blood purification,the blood transfusion amount during CRRT,total bilirubin (Tbil),serum creatinine (Cer), Na+,K+,prothrombin time (PT),activated partial prothrombin time (APTT),platelet count (PLT) before and after CRRT and the complications related to CRRT among the three groups were compared.Results The anticoagulation effect of the sodium citrate group was obviously better than that of the other two groups (χ2=18.809,P<0.05). The average service life of the pipelines of the sodium citrate group was (29.3±5.4) h, which was obviously higher than that of the heparin sodium group (16.5±3.5) h and the low molecular weight heparin calcium group (24.8±4.1) h,and the intergroup difference was statistically significant (F=6.596, P<0.05). The transfusion amount of red blood cells,plasma and platelets of the sodium citrate group was (12.3±2.8) U,(1875.5±198.6) ml and (23.5±8.6) U,which was obviously lower than that of the heparin sodium group [(16.5±5.6) U,(2463.4±265.4) ml and (58.3±18.5) U] and the low molecular weight heparin calcium group [(13.4±3.2) U,(1954.4±214.5) ml and (32.6±11.5) U],and the intergroup differences were all statistically significant (F=4.563,3.896,7.456;P<0.05). The Tbil,Cer,Na+ and K+ of all groups decreased after CRRT,and the differences were all statistically significant (P<0.05). There were statistical significance in PT,APTT and PLT among the three groups (F=4.562,4.153,5.468;P<0.05). The PLT of the sodium citrate group increased significantly after CRRT,with statistical difference (P<0.05). The incidence rate of hemorrhages in skin,digestive tract,puncture point and trachea of the sodium citrate group was respectively 2.8％,5.6％,2.8％ and 5.6％,which was obviously lower than that of the heparin sodium group (23.2％,12.5％, 16.1％,12.5％) and the low molecular weight heparin calcium group (6.3％,10.4％,8.3％,8.3％),and the differences were all statistically significant (χ2=6.678,7.553,6.849,7.534;P<0.05). The incidence rate of heparin induced thrombocytopenia (HIT) of the heparin sodium group was 8.9％ (5/56).Conclusions The anticoagulation effect of sodium citrate in CRRT is remarkable with less complications. It can significantly reduce the amount of blood transfusion and the cost of blood purification and is worth of promotion in clinical application.

BACKGROUNDIt is well known that more than 40% patients were initially diagnosed with advanced non-small cell lung cancer (NSCLC) with intrapulmonary or/and distant metastasis. However, up to now, the reports about effects of different metastatic sites on survival were limited. The aim of this study is to investigate the clinicopathologic and survival difference by retrospective analysis among sole intrapulmonary metastasis, sole extrathoracic distant metastasis and simultaneous metastasis of lung and other extrathoracic organs for the patients with advanced NSCLC, and to analyze the prognosis-related factors of NSCLC with intrapulmonary metastasis.

METHODSOf the 425 patients with stage IV NSCLC diagnosed by pathology and through staging evaluation and treated at Beijing Cancer Hospital with long follow-up during Oct. 1995 to Dec. 2003, 81 cases had sole intrapulmonary metastasis, 98 cases had sole extrathoracic distant metastasis and 68 cases presented simultaneous lung metastasis and extrathoracic spread. Kaplan-Meier survival curve was performed to estimate the survival of patients with different metastasis, Log-Rank test was used to compare their survival difference, and univariate analysis was used to find prognostic related factors.

RESULTSMedian survival time (MST) and 1-, 2-, 3-year survival rate (SR) for patients with sole intrapulmonary metastasis were 13 months (95% CI: 11-15), 57%, 21%, 7%, respectively; MST was 22 months (95% CI: 18-26) for patients with N1 and/or N2 and 10 months (95%CI: 7-13) for patients with N3 (P=0.001). Among the patients with ipsilateral, contralateral and bilateral intrapulmonary metastasis, difference of MST and 1-, 2-, 3-year SR had no statistical significance (P > 0.05); Survival of patients with sole intrapulmonary metastasis was not significantly different from that of patients with sole brain or bone metastasis (P > 0.05), but was longer than that of patients with simultaneous lung and extrathoracic spread (P=0.021). One way analysis of variance showed that no significant association were found among age, pathologic subtype, differentiation degree or response of first-line chemotherapy and survival of the patients with sole intrapulmonary metastasis (P > 0.05), but sex and invasive status of lymph node (N1/N2 vs N3) were found to influence the survival of the patients (P= 0.018, P=0.001). Further stratified analysis by age showed that invasion of lymph node was independent prognostic factor (P=0.002); whereas for the patients with simultaneous metastasis of lung and distant organs, metastatic numbers (2 vs ≥3) of organ were independent prognostic factor (P=0.013).

CONCLUSIONSNo statistical difference is found among survival of NSCLC patients with sole intrapulmonary metastasis and with sole brain, bone metastasis. Invasive status of lymph node and metastatic number of organ are important prognostic factors for patients with sole intrapulmonary metastasis and simultaneous metastasis of lung and extrathoracic organs, respectively.

OBJECTIVE: To detect potential mutations of the coagulation factor Ⅶ (F7) gene in a pedigree affected with hereditary FⅦ deficiency and explore its molecular pathogenesis. METHODS: The FⅦ antigen (FⅦ:Ag) was analyzed by an enzyme-linked immunosorbent assay (ELISA) method. Prothrombin time (PT), FⅦ activity (FⅦ:C) and other coagulant parameters were quantified with an one-stage clotting assay. The F7 gene was amplified by PCR and sequenced. Mutational sites were confirmed by reverse sequencing. Impact of amino acid substitution was assessed using SIFT and PolyPhen-2 software. Structure of the mutant protein was analyzed using Swiss-pdb Viewer software based on the three-dimensional structure in the Protein Data Bank. RESULTS: The propositus had prolonged PT (36.3 s), with FⅦ:C and FⅦ:Ag significantly reduced to 2% and 44%, respectively. Her father, mother, younger sister and daughter had slightly prolonged PT and reduced FⅦ:C (86%-120%). The FⅦ:Ag of her father and younger sister were also reduced. DNA sequencing revealed that the propositus has carried compound heterozygous mutations (Lys341Glu and IVS6-1G>A) of the F7 gene. Her father and younger sister were heterozygous for the IVS6-1G>A mutation, while her mother and daughter were heterozygous for the Lys341Glu mutation. Bioinformatics analysis indicated that Lys341Glu mutation may affect the stability and function of the FⅦ protein. CONCLUSION The Lys341Glu and IVS6-1G>A mutations probably underlie the reduced activity of FⅦ in this pedigree.
