One of its primary surgical treatments of tricuspid regurgitation is tricuspid valve biological valve replacement. Catheter tricuspid valve-in-valve implantation is a novel interventional alternative for biological valve failure. The non-invasive lung fluid measuring device remote dielectric sensing (ReDSTM) has been increasingly incorporated into clinical practice as a means of monitoring chronic heart failure in recent years. This report describes the process and outcomes of the first instance of perioperative lung fluid volume evaluation following transcatheter tricuspid valve implantation utilizing ReDSTM technology. The patient has a short-term, substantial increase in postoperative lung fluid volume as compared to baseline.

In China,peritoneal metastasis of gastric cancer has main characteristics of high incidence,late staging and poor prognosis.However,the proposal of conversion therapy has brought hope to patients.Conversion therapy of peritoneal metastasis in gastric cancer is a novel concept,which aims at down-staging of the gastric cancer's primary lesion and effectively controlling the peritoneal metastases at the same time through valid chemotherapy and other means.Then the surgeons strive for performing radical gastrectomy and lymph node dissection (D2) to prolong survival time of the patients with advanced gastriccancer and improve their life quality.Systemic chemotherapy is the core of the methods of conversion therapy,while the local intraperitoneal chemotherapy can be used as a supplement.Neoadjuvant intraperitoneal-systemic chemotherapy (NIPS) is the most promising technique as conversion therapy due to the comprehensive advantages of the systemic chemotherapy and local intraperitoneal chemotherapy.In recent years,there were many clinical studies reporting NIPS for conversion therapy of peritoneal metastasis in gastric cancer.Therefore,this paper systematically reviews experiences of clinical application in order to provide references for clinical practice of conversion therapy in gastric cancer.

Objective To investigate the risk factors of hyperbilirubinemia in late preterm infants. Methods The clinical data of 815 late preterm infants (449 males and 366 females) from 25 hospitals in Beijing were collected from October 2015 to April 2016, including 340 cases(41.7％) with hyperbilirubinemia (hyperbilirubinemia group), and 475 cases without hyperbilirubinemia (control group). The clinical data of two groups were compared, and the maternal factors influencing hyperbilirubinemia in late preterm infants were analyzed with logistic regression. Results There were no significant differences in gender ratio (M:F 1.39 vs. 1.12, t=1.811,P=0.172)and birth weight[(2502.6±439.6)g vs. (2470.2±402.9)g,χ2=2.330,P=0.127)]between two groups. The incidence rates of hyperbilirubinemia in infants of 34 wks, 35 wks and 36 wks of gestational age were 22.9％(87/174), 35％(119/300) and 42.1％(143/341) respectively (χ2=1.218,P=0.544). The multivariate logistic regression analysis indicated that the maternal age(OR=1.044,95％ CI:1.010-1.080,P=0.011)was independent risk factor and multiple births(OR=1.365,95％CI:0.989-1.883,P=0.048), premature rupture of membranes(OR=2.350,95％ CI:1.440-3.833,P=0.001), cesarean section(OR=1.540,95％CI:0.588-4.031,P=0.014)were risk factors for hyperbilirubinemia in late preterm infants. Conclusions The incidence of hyperbilirubinemia in late preterm infants is relatively high. Maternal age, multiple births, premature rupture of membranes and cesarean section are risk maternal factors related to hyperbilirubinemia in late preterm infants.

Objective To explore the effect of posterior debridement, grafting and internal fixation for treatment of non-specific lumbar intervertebral infection. Methods Clinical data of 20 patients with non-specific lumbar intervertebral infection treated in General Hospital of Ningxia Medical University from October 2013 to June 2013 were retrospectively analyzed. There were 15 males and 5 females with an average age of 41 years (range, 36-51 years). All patients suffered from single lumbar inter-vertebral infection, including 3 cases at L2/3,4 at L3/4,10 at L4/5 and 3 at L5/S1. All 20 cases underwent one-stage posterior debride-ment, autogenous bone grafting and internal fixation, tissue samples in focus were collected for bacterial culture and pathological examination. The disease controlling statues were evaluated based on laboratory results of ESR and CRP. Imaging examinations were taken to evaluate the fusion of vertebral body. Clinical effects were evaluated using the visual analog scale (VAS) and the Jap-anese Orthopaedic Association scores (JOA) score of lumbar fumction. Results All patients underwent the surgery successfully. The surgery duration time was 90-160 min, average 125 min, and the blood loss was 200-700 ml, average 360 ml. Cerebrospinal fluid leakage occurred in one case. Postoperatively, all patients experienced significant reliefof back pain, improving in the func-tion of movement, and no fever. The lower back VAS score: average (5.35 ± 1.15) points before operation , average (2.76 ± 0.34) points one week after operation, and an average score of (0.85±0.65) points by the last follow-up time. JOA lumbar function score:all patients were effective after operation, the improvement rate was excellent in 65%(13cases), good in 25%(5 cases), and pass-able in 10%(2cases). Comparing with preoperation, the excellent and good rate was 90%. All patients ESR and CRP returned to normal levels at the last follow-up. Ordinary bacterial culture was positive in 8 cases and negative in 12 cases. The pathogens iden-tified were staphylococcus aureus (6 cases), Escherichia coli (2 cases) and staphylococcus epidermidis (2cases). All incisions achieved primary healing. All patients were followed up from 6-18 months (average,12 months), and the symptom of pain relieved significantly. No recurrent infection had happened. A solid bony fusion was found in all patients at 6-14 months (average, 8.5 months) after the surgery. Conclusion Posterior debridement, grafting and internal fixation are effective treatments for non-spe-cific lumbar intervertebral infection, can reduce the time of staying in hospital, this operation is safe and reliable.

Aim Toexplorewhether1-methylhydan-toin(MH)could inhibit the basal secretion of growth hormone (GH ) and suppress the promoting effect of growth hormone-releasing hormone (GHRH ) in rab-bits.Methods Thirty-sixrabbitswererandomlydi-vided into six experimental groups according to the kind of dosing drugs,namely normal saline group(A), MH group (B ),octreotide group (C ),GHRH group (D),GHRH +MH group(E),GHRH +octreotide group(F),with 6 rabbits in each group.Blood was sampled (1. 0 mL each time)from each rabbit before injecting drugs and 5,15,30,45,60 min after drug administration.Clotting spontaneously,rabbits blood samples were centrifugated for 20 minutes at approxi-mately 1000 ×g and the supernatant was collected. Serum GH concentrations were determined by enzyme linked immunosorbent assay kit(ELISA Kit).Mean-while,the behavior of rabbits in each group after injec-tingdrugswascloselyobserved.Results TheGH level of rabbits in group A at each time point had no significant differences(P>0. 05 ).Group B and group C rabbit GH levels were significantly lower than those of group A (P<0. 05 ),while GH levels in group D were obviously higher than those of group A (P <0. 05 ).Compared with group D,rabbit GH levels in group E and group F decreased markedly(P<0. 05 ). No obvious toxic and side effects had been observed within one week after the experimental rabbits were ad-ministered corresponding drugs by intravenous injec-tion.Conclusions 1-methylhydantoincouldinhibit the basal secretion of GH in rabbits.1-methylhydan-toin could suppress the promoting effect of GHRH in rabbits.

Objective To investigate effects of two doses of dexmedetomidine (Dex) on the recovery quality from general anesthesia undergoing thyroidectomy.Methods A prospective randomized controlled double-blind trial was conducted in 90 patients admitted to Shengjing Hospital of China Medical University who were scheduled for thyroidectomy.They were randomly divided into three groups:group D0.4 received Dex 0.4 μg/kg intravenously,group D0.8 received Dex 0.8 μg/kg intravenously,and control group with same volume of normal saline.There were 30 patients in each group,and all the patients received the above drug or saline 30 minutes after intubation.The heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded before Dex administration,at the end of surgery,time of eye opening and extubation,and 10 minutes after extubation.Time of eye opening after surgery and time of extubation after eye opening were recorded.End-tidal partial pressure of carbon dioxide (PETCO2) before and after operation as well as restlessness score (RS),Ramsay sedative score,and visual analogue pain scale (VAS) scores at 10 minutes after extubation were recorded.Events during extubation including cough,nausea and vomiting,respiratory depression were also recorded.Results ① Compared with control group,in D0.4 and D0.8 groups incidence of lowering of HR,SBP and DBP was lower at time of eye opening and extubation,and 10 minutes after extubation.Compared with D0.4 group,D0.8 group had lower HR at the time of extubation and 10 minutes after extubation,SBP was lower at the time of eye opening and extubation,and lower DBP at the time of eye opening.② D0.4 and D0.8 groups showed lower RS and VAS scores than those of control group,Ramsay sedative score in groups D0.4 and D0.8 was higher than that in control group (RS:1.40±0.51,1.20±0.42 vs.1.90±0.56; VAS:1.50±0.52,0.80±0.63 vs.2.50 ± 0.52; Ramsay:2.10 ± 0.56,2.40 ± 0.51 vs.1.60 ± 0.51,P＜0.05 or P＜0.01),and VAS score in group D0.8 was lower than that in D0.4 group (P＜0.01).The time of eye opening and extubation were longer in group D0.8 as compared with those in control and D0.4 groups (minutes:12.50 ± 1.08 vs.10.50 ± 1.58,10.40 ± 1.26; 15.00 ± 0.94 vs.13.00 ± 1.63,12.80 ± 1.13,P＜0.05 or P＜0.01),but there was no significant difference between the latter two groups.No significant difference in PETCO2 was found among three groups before and after surgery.③ The incidence rate of cough,nausea and vomiting in control group (16.7％,13.3％) were significantly higher than those in groups D0.4 (3.3％,0) and D0.8 (0,0).There was no respiratory depression in the three groups.Conclusion Adjunctive infusion of Dex 0.4 μg/kg at 30 minutes after anesthesia induction was recommended as it may result in more steady hemodynamics,with shorter recovery time and extubation time after thyroidectomy.

Objective To discuss the influence of comprehensive rehabilitative nursing by traditional Chinese medicine(TCM)the neural function impairment, activity of daily living(ADL)and accompanying complications of patients in acute phase of cerebral apoplexy. Methods 238 patients from 3 cooperative hospitals from September in 2004 to September in 2006 were randomly chosen and divided into the test group(117 cases)and the control group(121 cases).The medication treatment in the two groups were basically the same. The comprehensive rehabilitative nursing with traditional Chinese medicine was adopted in the test group and the control group received routine nursing intervention. The clinical nerve function limitation score(CNS)and the ADL were evaluated within the first week and the 4th week after intervention. The incidence rate of complications was also determined. Results The CNS and ADL results in the observation group were better than those in the control group(P＜0.01).The incidence rate was lower than that in the observation group. Conclusion The comprehensive rehabilitative nursing by TCM could facilitate the functional recovery of limbs and improve activity of daily living.This intervention could be applied in clinic, family and community because of its characteristics such as simplicity, feasibility and little adverse effect.

Objective To compare a potential role of dendritic cells (DCs) and macrophages in inducing protective immunity against infection with Schistosoma japonicum. Methods DCs and macrophages were pulsed in vitro with soluble egg antigen (SEA) of S. japonicum. BALB/c mice were injected three times with DCs or macrophages, either antigen-pulsed or not,and challenged with 40 ± 2 cercariae of S. japonicum per mouse. Worms were collected 42 days later by portal perfusion of the mice and egg number of liver was calculated. To evaluate whether protective immunity had been induced by preparations of DCs or macrophages, the worm burden and fertility ( eggs per female per mouse liver) were compared between the groups of mice. The antibody level against SEA was detected by ELISA. Results With respect to mice injected with untreated cells, numbers of worms and eggs per female worms were significantly reduced in the groups of mice having received pulsed DCs (26. 3% and 37.9%, respectively), or pulsed macrophages (22. 0% and 30.7%). Untreated DCs and macrophages induced no significant effects. The antibody level against SEA rose in sera of all groups of mice up to 42 days after the challenge, but most pronounced in those immunized with pulsed DCs, although this was not significantly different from other groups. Conclusion The results suggest that the protective immunity against S. japonicum might be induced by DCs to a higher extent than by macrophages after in vitro pulsing with egg antigen.

In order to construct recombinant baculovirus carrying Schistosoma japonicum 26 ku glutathione S-transferase gene (Sj26), and observe the expression of Sj26 in mammalian cells, the Sj26 gene was amplified with plasmid pGEX-3X as template by PCR, and then recombined into T vector for sequencing. Sj26 gene was inserted into the downstream of CMV promoter of donor plasmid pFBDGC, and the recombinant donor plasmid pFBDGC-Sj26 transformed into DH10Bac, then the recombinant bacmid AcCMVSj26 was isolated and transfected into Sf9 cells. The recombinant baculovirus was harvested and final titer of vAcCMVSj26 was measured. BHK cells were transducted with recombinant baculovirus in vitro. By using Western blot, the expression of 26 ku glutathione S-transferase (GST) was detected. The results showed that after enzyme digestion and sequencing, the donor plasmid was successfully constructed. PCR confirmed that pFBDGC-Sj26 and Bacmid homologous recombination occurred in E. coli. After transfection of Sf9 cells with recombinant Bacmid, recombinant baculovirus was replicated in Sf9 cells and expressed green fluorescent protein. PCR further revealed recombinant baculovirus contained Sj26. The titer of the harvested baculovirus was 1.24 x 10(8). Western blot demonstrated that recombinant baculovirus could express 26 ku GST in BHK cells. It was concluded that Sj26 recombinant baculovirus was successfully constructed, and the 26 ku GST was expressed in mammalian cells.
