Objective To investigate the needs and its satisfaction degrees of the family members of ICU patients at the different stages. Methods 27 patients' family members who were complied to the selected standard were investigated by the Critical Care Family Needs Inventory (CCFNI) and the Needs Met Inventory (MNI) within 24 hours and after 72 hours separately after the patients were admitted in the ICU. Results The subscale of assurance of the patients was the important one of patients' family members' needs, so there was no statistical significance between the condition within 24 h and the condition after 72 h (P > 0.05). The conditions of support acquisition and comfort after 72 h were obviously higher than the conditions within 24 h, so the difference had statistical meaning (P < 0. 01). The degrees of satisfaction after 72 h was higher than that within 24 h. Sufficiency in information after 72 h was obviously higher than that within 24 h, showing a statisticeal meaning (P <0.01). Conclusions The needs and its satisfaction degrees of ICU patients' family members at the different stages are different. The ICU medical staff should pay full attention to all kinds of patients' needs, thereby increasing their satisfaction degrees.

OBJECTIVE: To determine the effects of naoyian (NYA) serum on the expression of vascular endothelial growth factor (VEGF) protein in cultured rat cerebral microvascular endothelial cell (RCMEC) with hypoxia. METHODS: NYA serum was separated from rat heart which had been filled stomach with NYA successively for 3 days. The rat cerebral microvascular endothelial cells were taken from the Sprageu-Dawley rat brain at postborn 7 days. The rat cerebral microvascular endothelial cells were incubated at anaerobic incubator to establish the hypoxia models. The vigo of RCMEC was determined by MTT. The level of expression of VEGF protein was measured by cell immunohistochemistry and Western blot. RESULTS: The OD value of NYA serum group was higher than the control groups after hypoxia for 18 hours. VEGF protein was increased by hypoxia in cerebral microvascular endothelial cells (P < 0.05). The content of VEGF protein in NYA serum containing medium was more significantly elevated than those cultured in other control media (P < 0.01). CONCLUSION VEGF protein was induced by hypoxia in rat cerebral microvascular endothelial cells, and NYA could upregulate the expression of VEGF protein, which may be one of the protection mechanisms for cerebral microvascular endothelial cells.

OBJECTIVETo observe the dynamic changes of Th17/Treg balance in patients following surgical intervention for intracranial aneurysm rupture.

METHODSThe percentage of Th cells and the intracellular IL-17 level, Treg cell percentage and transforming growth factor -β1 (TGF-β1) levels were examined in 73 patients with rupture of aneurysms before and at 24 h, 72 h and 1 week after operation, with 62 patients with unruptured aneurysms and 65 healthy volunteers as the control. The correlations among the immune cells, cytokines and clinical characteristics of the patients (NIHSS, ADL and hospitalization stay) were analyzed.

RESULTSTh17 percentage and intracellular IL-17 levels were significantly higher in the patients with ruptured and unruptured aneurysms than in the healthy volunteers, and were significantly higher in patients with ruptured aneurysms than in those with unruptured aneurysms. Treg cell percentage and TGF-β1 level were significantly lower in patients with aneurysms than in the healthy volunteers, and were lower in patients with ruptured aneurysms than in those with uruptured aneurysms (P<0.05). Patients with intracranial aneurysm rupture showed significantly increased Th17 cell percentage and IL-17 level but significantly lowered Treg cell percentage and TGF-β1 at 24 h following the surgery (P<0.05); these changes were reversed significantly at 72 h and 1 week after the surgery. Th17 cell percentage and IL-17 level were positively correlated with NIHSS and the length of postoperative hospital stay but inversely correlated with ADL; Treg cell percentage and TGF-β1 were inversely correlated with NIHSS and hospital stay but positively with ADL (P<0.05).

CONCLUSIONIn patients with intracranial aneurysms, the systemic immune inflammatory response is highlighted by excessive Th17 cells and insufficient Treg cells, which are closely related with the outcomes of the patients following surgical intervention. Evaluation of Th17/Treg balance and the cytokine levels can help to assess the prognosis of patients with aneurysm rupture.

Objective The objective of this research is to construct a clinic-usable genechip method for detection of hepatitis B virus lamivudine-resistant mutants and basal core promotor/Pre-C mutants, compare this method with DNA sequencing to investigate this genechip's character (semity, specificity, stability and practicability in clinic) and apply it in clinic. Methods This genechip detection method can detect the DNA and 8 mutative site of HBV, include 3 lamivudine-resistant mutation site (No. 180, 204, 207 site in DNA polymerase gene) ,5 HBeAg escape-related mutation site(nt 1896, 1899, 1862, 1764, 1762 site in BCP/Pre-C region).The results of genechip method was verified by DNA sequncing. Results In detecting HBV DNA, the results of genechip were agree with 100% of the results of DNA sequencing. In detecting HBV mutants, 251 sites (in 32 samples, 256 sites) showed the same results using both methods, and only 5 sites were not completely match(P >0.05). In these 5 sites, genechip methods got multi-infection results, but sequencing got single-infection results.Conclusion These results suggest that genechip method has the same positive rate and almost these same specificity with DNA sequencing method, and is better than DNA sequencing method in detecting multi-infected HBV strains.

Aim To investigate the effectiveness and safety of alfentanil in general anesthesia.Methods In this study, a multicenter randomized double-blind con¬trolled study was conducted.A total of 352 subjects were selected and randomly assigned to fentanyl group (group A, n =176) and alfentanil group (group 15, n = 176).Anesthesia induction: intravenous midazolam 0.03 mg • kg-1 + fentanyl 25 p.g • kg"'(group A) or alfentanil 4 p,g • kg-1 ( group 15) + propofol 2 mg • kg"1 + rocuronium 0.8 mg • kg"1.Sevoflurane + fent¬anyl ( group A ) or alfentanil ( group B ) + rocuronium were used for anesthesia.The vital signs of patients re¬covery time and extuhation time, anesthesia-related complications and the use of related remedial drugs during anesthesia induction and maintenance were compared between the two groups.Results During the induction and maintenance period of anesthesia, alfentanil and fentanyl could equally effectively inhibit the stress response induced by endotracheal intubation and surgical stimulation.Alfentanil also showed more effective inhibition on stress response induced by endo¬tracheal intubation and surgical stimulation than that of fentanyl ( P < 0.05 ) .However, there was no signifi¬cant difference in the incidence of intraoperative hypo¬tension and hypertension and the time of anesthesia re¬covery and extubation between the two groups.Conclu¬sions Both alfentanil and fentanyl can effectively in¬hibit the stress response induced by surgical stimulation and could be safely used in general anesthesia in sur¬gery.Alfentanil has more advantages in maintaining the stability of blood pressure and heart rate during an¬esthesia induction and maintenance.

OBJECTIVE: To analyze the hematological characteristics of HbE homozygotes. METHODS: Complete blood cells count and hemoglobin electrophoresis were used for phenotypic analysis of 78 cases with HbE homozygotes from Yunnan province, China. The PCR-fluorescence hybridization was used to detect the common gene mutation of thalassemia. The hematological indexes, including MCV, MCH, Hb, HbA2, HbF and HbE were statistically analyzed between groups with different sex, ages and compound α thalassemia status. RESULTS: In HbE homozygotes (HbEE), 89.5% (17/19) children presented mild to moderate microcytic hypochromic anemia, and 10.5% of them presented moderate anemia. 39.6% (19/48) of women with HbEE developed mild anemia ,while 11 cases of male with HbE homozygotes were asymptomatic. The levels of MCV and MCH in HbE homozygotes increased by co-inheritance of α thalassemia mutation. CONCLUSION The clinical phenotype of HbE homozygote shows highly heterogeneous, which is relates with age, sex and co-inheriting α-globin genotypes. In Hb EE women and children are more likely to develop mild to moderate anemia. The microcytic hypochromic anemia degree is relieved when HbEE combined with α- thalassemia.

Objective: To analyze the safety and efficacy of combined left atrial appendage (LAA) and patent foramen ovale (PFO) closure in adult atrial fibrillation (AF) patients complicating with PFO. Methods: This study is a retrospective and cross-sectional study. Seven patients with AF complicated with PFO diagnosed by transesophageal echocardiography (TEE) in Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences from June 2017 to October 2020 were selected. Basic data such as age, gender and medical history were collected. The atrial septal defect or PFO occluder and LAA occluder were selected according to the size of PFO, the ostia width and depth of LAA. Four patients underwent left atrial appendage closure(LAAC) and PFO closure at the same time. PFO closure was performed during a one-stop procedure of cryoablation combined with LAAC in 2 patients. One patient underwent PFO closure at 10 weeks after one-stop procedure because of recurrent transient ischemic attack (TIA). All patients continued to take oral anticoagulants. TEE was repeated 8-12 weeks after intervention. In case of device related thrombus(DRT), TEE shall be rechecked 6 months after adjusting anticoagulant and antiplatelet drug treatment. Patients were follow-up at 1, 3, 6, 12, 24 months by telephone call, and the occurrence of cardio-cerebrovascular events was recorded. Results: Among the 7 patients with AF, 2 were male, aged (68.0±9.4) years, and 3 had a history of recurrent cerebral infarction and TIA. Average PFO diameter was (3.5±0.8)mm. Three patients were implanted with Watchman LAA occluder (30, 30, 33 mm) and atrial septal defect occluder (8, 9, 16 mm). 2 patients were implanted with LAmbre LAA occluder (34/38, 18/32 mm) and PFO occluder (PF1825, PF2525). 2 patients were implanted with LACbes LAA occluder (24, 28 mm) and PFO occluder (PF2525, PF1825) respectively. The patients were followed up for 12 (11, 24) months after operation. TEE reexamination showed that the position of LAA occluder and atrial septal defect occluder or PFO occluder was normal in all patients. DRT was detected in 1 patient, and anticoagulant therapy was adjusted in this patient. 6 months later, TEE showed that DRT disappeared. No cardiovascular and cerebrovascular events occurred in all patients with AF during follow-up. Conclusions: In AF patients complicated with PFO, LAAC combined with PFO closure may have good safety and effectiveness.
