Objective To analyze the appropriate time selection of pregnancy and delivery in women with systemic lupus erythematosus (SLE ). Methods Twenty-nine pregnancies in women with SLE in our hospital from 1998 to 2003 were retrospectively analyzed regarding the selection of appropriate time of pregnancy and delivery. Results All patients did not take any cytotoxic medicine for at least 6 months before pregnancy. Twenty-three conceptions occurred when SLE was inactive for at least 1 year. Two conceptions occurred when SLE was active without doctors' agreement SLE was diagnosed during pregnancy in the remaining 4 cases. The condition of all patients fluctuated and the gestational time at delivery ranged from 30 to 38 weeks after we modified the doses of glucocorticoid (prednisone). Among totally 29 living neonates, eight were premature neonates, three were FGR and one had serious congenital heart disease. Two neonates died of complications in early stage of neonatal period. None of the 29 neonates from all patients had neonatal lupus. Conclusion Pregnancy safety will be improved obviously if the condition of SLE is controlled and the patients are given reasonable doses of glucocorticoid and intensive monitoring. If pharmacotherapy does not work well and the condition threatens the safety of mother and fetus, or the fetus has matured, termination of pregnancy should be done on time, which reduces maternal complications and improves the perinatal mortality rate. The gestational time should be 34 to 38 weeks.

OBJECTIVE: To study the effect of hypertonic seawater and isotonic seawater for nasal mucosa of allergic rhinitis mice model, and explore the possible mechanism of nasal irrigation with seawater in treatment of allergic rhinitis. METHOD: We used Der pl to make allergic rhinitis model of BALB/c mice, and divided them into three groups randomly. Nasal irrigation with hypertonic seawater (HS) or isotonic seawater (IS) in the treatment group 1-14 days after modeling, and black control (BC) group was given no treatment after modeling. Normal control (NC) group was given no treatment, the number of rubs and sneezings in each group were counted in 30 min after the last nasal irrigation. Mice were then killed 24 h after the last therapy. The noses of mice from each group were removed and fixed, then the slices were stained with hematoxylin and eosin, the others were observed by transmission electron microscope. RESULT: Mice with hypertonic seawater and isotonic seawater were significantly improved in rubs and sneezings compared to the black control group (P<0. 05); The number of eosinophiles in mucosal tissues of HS group and IS group had no significant difference with that of the black control group (P> 0. 05); Ciliated columnar epithelium cells in mucosal tissues of HS group and IS group were arranged trimly, better than that in the black control group. Morphology and microstructure in nasal mucosal of HS group was closer to the normal group than in IS group. CONCLUSION The injury of nasal mucosa ciliated epithelium was significantly improved by nasal irrigation with hypertonic seawater and isotonic seawater, and the former is better than the latter, the mechanism of nasal irrigation with seawater in treatment of allergic rhinitis may rely on repairing the injured nasal mucosa ciliated epithelium, thereby the symptoms of nasal was reduced.

Objective To census the preoperative prevalence rate of deep venous thrombosis (DVT) and to evaluate the risk factors of DVT in senile osteoporotic hip fractured patients.Methods The object of study were patients aged 60 and above, and osteoporotic hip fracture by low energy injury in 2013.Based on medical records, all the patients with osteoporotic hip fracture were evaluated the signs and symptoms of DVT in 24 h, D-dimer test and underwent Doppler ultrasound screening of bilateral venous system in lower extremity after admission, and all the patients received preoperative prophylactic anticoagulation.Patients with popliteal and proximal level thrombus or floating thrombus underwent inferior vena cava (IVC) filter insertion.Outcome measures: age, gender, fracture type, D-dimer value in 24 h preoperatively, occurrence time of DVT and region, grade of preoperative American Society of Anesthesiologists, preoperative medical diseases.Results 702 of 946 hip fracture inpatients were comprised in this retrospective study.All were not founded any symptom or signs of DVT.All patients were took preoperative Doppler ultrasound screening and the results as follows: 36 of 302 patients (11.9％) with femoral neck fracture were proved preoperative thrombosis(13 male, 23 female), the average age was 72.7 year-old(range from 62-90 year-old), on the same side as the fractured hip in 31 patients, bilateral thrombosis in 5 patients.74 of 400 patients (18.5％) with intertrochanteric fracture were proved preoperative thrombosis(38 male, 36 female), the average age was 76 year-old (range from 60-95 year-old), on the same side as the fractured hip in 68 patients, bilateral thrombosis in 6 patients.The most prevalence rate of DVT were in the first day after osteoporotic hip fracture, 15 patients (41.7％) with femoral neck fracture and 38 patients (51.40％) with intertrochanteric fracture.There were more proximal level and multiple level involment thrombosis over 5 days after injury.The most thrombosis were proven at calf and popliteal vein.Conclusion The prophylaxis of DVT should be started even in the emergency department in senile patient with osteoporotic hip fracture.To avoid the risk factors, early surgery and early postoperative mobilization will be effective.

Objective To study the feature of neonatal infections and characteristics of antibiotic treatment in a tertiary children ' s hospital. Methods Clinical data including incidence of infection, primary disease,species of bacteria, complication and antibiotic utilization in hospitalized patients from Jan. 2010 to Dec. 2012 were retrospectively reviewed using their medical records. Results Among 1826 patients admitted to neonetal surgery ward, 542 infants ( 29. 7％) were with infection. The incidence of antibiotic resistance was 23. 51％. The top five infectious diseases were:perianal abscess, necrotizing enterocolitis, colicitis, omphalitis and subcutaneous gangrene. 12 cases of multi-resistant infection were cured by non-restricted antibiotics. 109 were cured by restricted antibiotics. And other 7 were cured by special antibiotics. No death nor multi-resistant nosocomial infection were found. Risk factors including multi-site infection, premature or low birth weight infants, liver, kidney or heart dysfunction,fever lasting more than 3 days after antibiotic therapy, septic shock, sepsis, digestive tract perforation and peritonitis,were vital in choosing specific antibiotics. Conclusions Infection is one of the most common diseases in neonatal surgery ward, with major pathogens sensitive to antibiotics. The clinical characteristics and drug sensitive test are conductive to the reasonable use of antibiotics. Special antibiotics can be used directly in patients with risk factors Clinical doses of antibiotics in neonates depend on the monitoring of drug concentration.

The nuclear transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays a crucial role in maintaining cellular redox homeostasis. The aberrant NRF2 signaling confers enhanced antioxidant capacity, which is linked to tumor progression and therapeutic resistance. The current study investigates the biological effects and molecular mechanism of tribbles homolog 3 (TRIB3), a stress-induced protein, in regulating cell survival and apoptosis in lung cancer. This study first performed the RNA sequencing data analysis with 576 lung adenocarcinoma patients from the cancer genome atlas (TCGA) database. The NRF2- antioxidant response element (ARE) signature was enriched in patients with high TRIB3 expression. Dual-luciferase reporter assay and real-time quantitative polymerase chain reaction (PCR) were used to confirm the effect of TRIB3 on the kelch-like ECH-associated protein-1 (KEAP1)-NRF2 pathway. Abrogation of TRIB3 impaired NRF2 transcriptional activity and reduced the expression of its target genes. Moreover, TRIB3 enhanced NRF2 stability via blocking KEAP1-NRF2 interaction. TRIB3-depletion promoted reactive oxygen species (ROS) production, restrained cell proliferation, and enhanced carboplatin-induced apoptosis. In addition, NRF2 overexpression recovered the tumor inhibition effect of TRIB3-depletion. Consistently, TRIB3 failed to modulate apoptosis in NRF2 depletion cells. In summary, this study shows that TRIB3 inhibits the KEAP1-NRF2 interaction and upregulates the transcriptional activity of NRF2, thereby promoting lung cancer cell proliferation and reducing the sensitivity to chemotherapy. Targeting the TRIB3-NRF2 signal axis may become a new strategy for ROS homeostasis and lung cancer treatment.

Objective To evaluate the melancholia incidence in the convalescence period of cerebral hemorrhage and its correlated factors.Methods Ninety-eight cerebral hemorrhage patients in the convalescence period were involved in this study.Melancholia was assessed by Hamilton depression scale (HAMD),neural functional deficiency was assessed by the national institute of health stroke scale (NIHSS),cognitive function deficiency was assessed by the Montreal cognitive assessment (MoCA) and neural functional deficiency recovery was assessed by modified Rankin scale (mRS).Hemorrhagic site and blood quantity were detected with CT.The blood flow of middle cerebral artery (MCA),anterior cerebral artery (ACA),posterior cerebral artery (PCA) was detected by TCD.Results The melancholia incidence in the convalescence period was 51.0％(50/98),34.0％(17/50) in males and 68.8％(33/48) in females,there was significant difference between the two (P ＜ 0.05 ).The scores of NIHSS and mRS had significantly positive correlation with HAMD (P ＜ 0.05 ),and had significantly negative correlation with MoCA (P ＜ 0.05 ).When the hemorrhagic site was in frontal lobe and blood quantity was 20-40 ml,the melancholia incidence was increased [76.2％ (16/21),62.5％ (25/40)].The average blood velocity of MCA,ACA and PCA in melancholia patients was significantly slower than that without melancholia patients,while resistance index was significantly higher in melancholia patients (P ＜ 0.05).Conclusions Melancholia incidence in the convalescence period of cerebral hemorrhage has positive correlation with sex,NIHSS,MoCA,hemorrhagic site and blood quantity.The average cerebral blood flow in the melancholia patients is significantly slower and resistance index is significantly higher.

We describe two cases in which a forceps imprintdeveloped in the AcrySof ReSTOR IOL optic whileinserting these IOLs into the cartridge with straightclamping forceps. In case 1 ,the AcrySof ReSTOR IOL wasexplanted and observed under scanning electronmicroscopy (SEM). The SEM showed that the stepdesign of ReSTOR Multifocal IOL was well maintained. Incase 2, visual acuity, contrast sensitivity and wavefrontmeasurements were performed and no specific changeswere found. Strong evidence does not exist that suggeststhe on-axis forceps imprint can significantly compromisevisual acuity.

Patients with hypoxia pulmonary hypertension (HPH) are often accompanied by dyspnea, fatigue, and headache. With the development of the disease, the right ventricle gradually collapses and eventually leads to death. Hypoxic pulmonary vascular remodeling is an important pathological basis of HPH, and the remodeled pulmonary vessels will form permanent thickening. The mechanism of hypoxic pulmonary vascular remodeling is relatively complex. At present, there are few studies on drugs for pulmonary vascular remodeling on the market, mainly focusing on the alleviation of pulmonary vasoconstriction. It was found that hypoxia induces calcium overload in pulmonary artery smooth muscle cells (PASMCs), resulting in the proliferation of PASMCs. The main mechanisms include: ① abnormal expression of calcium pumps; ② abnormal calcium channels in the plasma membrane of pulmonary artery smooth muscle cells; ③ overexpression of calcium-sensitive receptors in cells; ④ the expression of Na⁺/Ca²⁺ exchanger type-1 was abnormal. This review summarized several mechanisms of hypoxia induced calcium overload leading to pulmonary artery remodeling, hoping to provide a new idea for the treatment of HPH.

Objective:To investigate the correlation between chronic renal insufficiency (CRF) and helicobacter pylori (HP) infection in elderly patients and the relative clinical treatment effects.Methods:In this study, 150 elderly patients with CRF were selected as the observation group and 40 health individuals who were confirmed in the physical examination were selected as the control group.All of them underwent examination of 14C-urea breath test (UBT) so as to diagnose the HP infection rate.100 patients with CRF combined with HP infection in 150 elderly patients with CRF were divided into sequential treatment group (50 cases) and triple treatment group (50 cases) according to the random number table method.The two groups were implement sequential treatment and routine triple treatment, respectively, and the clinical effects of the two methods were evaluated after they were continuously treated 10 d.The clearance rate of HP and symptom score of the two methods were compared, and the safeties of the two methods were evaluated by the examining functions of liver and kidney.Results:The results of 14C-UBT showed that the HP infection rate was 72％ (108cases) in observation group, which was significantly higher than that (32.50％) in control group (x2=28.324, P<0.05) .The clearance rate of HP in sequential treatment group was 98.00％, which was significantly higher than that (88.00％) in triple treatment group, and the clinically effective rate in sequential treatment group was 94.00％, which was significantly higher than that (84.00％) in triple treatment group, and the differences of them was statistically significant (x2=4.231, x2=5.576, P<0.05) .The scores of abdominal distension, abdominal pain, belching and anorexia of sequential treatment group were significantly lower than those of triple treatment group after treatment (t=12.432, t=1.223, t=10.276, t=9.326, P<0.05) .Besides, the differences of indicators of liver and kidney function between sequential treatment group and triple treatment group after treatment were no significant (t=12.432, t=1.223, t=10.276, t=9.326, P<0.05) .Conclusion:The incidence rate of HP infection in elderly patients with CRF is significantly higher than those of healthy people.For patients with CRF, routine HP detection should be carried out, moreover, compared with triple treatment, sequential treatment holds a more effective and safe therapeutic outcome.
