Objective To explore the difference of gene expression profiling between normal basilar arteries and basilar arteries of cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) in rabbits. Methods cDNA chip of normal basilar arteries and basilar arteries of CVS after SAH in rabbits were downloaded from GEO database. The chip was analyzed and screened by Bioconductor software, and function enrichment and pathway analysis of the differentially expressed genes were analyzed by Cytoscape software. Then 6 adult male Japanese rabbits were used, and randomly divided into normal control group (n=3) and SAH model group (n=3). Rabbit SAH models were established by cisterna secondary-blood-injection method. RNA data of normal basilar artery specimens on the 0 day and basilar artery specimens after SAH on the 5-day were used to validate the parts of differentially expressed genes by qRT-PCR. Results A total of 4356 differentially expressed genes were found in normal basilar arteries and basilar arteries of CVS after SAH in rabbits. Among them, 920 genes were considered to be significant with P-value<0.05, such as GRIK1, MYH13, ZNF45, SAA3, RLN1, MSR1 and others. Function enrichment analysis indicated that the differentially expressed genes were involved in regulation of Ca2+transmembrane transporter activity, negative regulation of ion transmembrane transport, regulation of potassium ion transport, positive regulation of JAK-STAT signaling cascades and other biological processes. Pathway analysis showed that calcium signaling pathway, cGMP-PKG signaling pathway, HIF-1 signaling pathway, PI3K-Akt signaling pathway and other signaling pathways maybe related with the differentially expressed genes. qRT-PCR verification showed that the expression of MSR1 in SAH model group was consistent with that of the chip result. Conclusion The gene expressions of basilar arteries of CVS after SAH in rabbits are significantly different, and MSR1 gene can be used as a potential target for studying the pathological mechanism of CVS.

Objective To investigate the application effect of interventional surgery in the treatment of facial superficial mixed hemangi-oma through the laryngeal mask ventilation under desflurane anesthesia. Methods In the period from February 2016 to April 2017 in our hospital 118 cases of facial superficial hemangioma under interventional surgery in infants( aged 3-15 months) were retrospectively analyzed;according to the difference of anesthesia,they were divided into control group (51 cases) and observation group (67 cases);the two groups of children were administered sufentanil anesthesia, in the control group laryngeal mask airway under propofol, the observation group was giv-en under laryngeal mask airway inhalation of desflurane maintenance. Then was compared the difference in anesthesia monitoring indexes of the two groups, such as mean arterial pressure ( MAP) , saturation of pulse oximetry ( SpO2 ) , heart rate ( HR) , end-tidal carbon dioxide ( ETCO2 ) , laryngeal mask removal time, loss of consciousness time, laryngeal mask removal time, consciousness recovery duration, clinical efficacy and intraoperative and postoperative adverse reactions difference. Results For the control group, the laryngeal mask removal time and consciousness recovery time length were significantly longer than those of the observation group and the difference was statistically signifi-cant (P<0. 05);after anesthesia induction, the laryngeal mask insertion time, operation start time and laryngeal mask removal time, MAP and HR of the observation group and the control group were lower than those before anesthesia induction, and MAP and HR of control group were lower than those of the observation group and the deference was statistically significant (P<0. 05). The total efficiency of the observa-tion group (97. 02％) was significantly higher than the control group (88. 24％), the adverse reaction rate (23. 52％) of children in the control group was significantly higher than that (7. 46％) of those in the observation group, and the differences were statistically significant (P<0. 05). Conclusion In the infant facial superficial hemangioma interventional surgery, laryngeal mask airway can be used for anesthe-sia maintenance for desflurane effect and clinical curative effect in the effective protection of anesthesia at the same time, but also can reduce the risk of anesthesia and intraoperative blood pressure fluctuations, especially in the stabilization of hemodynamics of the patients.

OBJECTIVE: To study the effect of red blood cell (RBC) storage duration on the clinical effect of exchange transfusion (ET) and internal environment in neonates with hyperbilirubinemia. METHODS: A retrospective analysis was performed for the clinical data of 135 neonates with hyperbilirubinemia who received ET between January 2015 and August 2018. According to RBC storage duration, the neonates were divided into short-term storage group (RBCs were stored for ≤7 days) with 56 neonates and long-term storage group (RBCs were stored for >7 days) with 79 neonates. The two groups were compared in terms of serum total bilirubin (TBIL) level and the rate of TBIL reduction at 0 and 12 hours after ET, as well as the duration of continued phototherapy and rate of repeated ET. Routine blood test parameters, electrolytes, blood glucose, and blood gas parameters were measured before ET and at 0 hour after ET. RESULTS: At 0 hour after ET, there were no significant differences in the TBIL level and the rate of TBIL reduction between the two groups (P>0.05). At 12 hours after ET, the long-term storage group had a significantly higher TBIL level and a significantly lower rate of TBIL reduction than the short-term storage group (P<0.01). The long-term storage group had a significantly longer duration of continued phototherapy after ET than the short-term storage group (P<0.05). Compared with the short-term storage group, the long-term storage group had significantly higher incidence rates of ET-related complications, including hyponatremia, hyperkalemia, and metabolic acidosis (P<0.05). CONCLUSIONS The use of RBCs with a storage duration of >7 days in ET for neonates with hyperbilirubinemia does not affect the immediate effect of ET, but these neonates tend to have a poor outcome after continued phototherapy and high risk of hyponatremia, hyperkalemia, and metabolic acidosis.

MHNTs@PDA@ZIF-8 with rod-shaped core-shell structures was synthesized and used as sorbent in magnetic solid phase extraction(MSPE).MHNTs@PDA@ZIF-8-MSPE method coupled with gas chromatography-mass spectrometry(GC-MS)was employed to analyze sixteen kinds of polycyclic aromatic hydrocarbons(PAHs)in tea beverages.Vibrating sample magnetometer(VSM),Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD),scanning electron microscopy(SEM)and nitrogen adsorption-desorption techniques were used to characterize the MHNTs@PDA@ZIF-8.The results demonstrated that the MHNTs@PDA@ZIF-8 exhibited significant magnetic properties and a large specific surface area.The experimental conditions that could affect MSPE were investigated,including adsorbent dosage,extraction time,desorption time,ionic strength,desorption solvent type,and desorption solvent volume.The optimal conditions were 10 mg of MHNTs@PDA@ZIF-8 as adsorbent,90 s under vortex extraction,and ultrasonic desorption for 60 s with 1 mL ofn-hexane.The sixteen kinds of PAHs showed good linearity in the concentration range of 5-500 μg/L(r2≥0.995).The limits of detection(S/N=3)and quantitation(S/N=10)were in the range of 0.1-0.8 μg/L and 0.3-2.6 μg/L,respectively.The recoveries of the method ranged from 60.9%to 114.7%,with relative standard deviations(n=3)ranging from 0.2%to 9.2%when the addition levels of sixteen kinds of PAHs were 10,50,and 100 μg/L.The method was simple,fast,sensitive and environmentally friendly,and suitable for detecting sixteen kinds of PAHs in tea beverages.

OBJECTIVE:To study the current status of cesarean section rate(CSR)and cesarean section(CS)indications in Shanghai,and to provide basic evidence for reducing the rate of CS.METHODS:Six general and maternal and child hospi⁃tals(MCH)in Shanghai were selected,and all data of childbirth of these hospitals in 2016 were collected.The total CSR was calculated for all hospitals and the Chi-square tests were used to compare the CSR among different hospitals.The constitution of CS indications were reported by using the data collected from two out of the six hospitals.RESULTS:The to⁃tal CSR of all hospitals in this study was 47.88%(95% CI 47.30%-48.46%).The CSR in suburb an hospitals was signifi⁃cantly higher than that in outer suburbs and city center(51.72% vs. 50.54% vs. 43.24%,P<0.01),The CSR in secondary hospitals was significantly higher than that in tertiary hospitals(49.73% vs. 46.36%,P<0.01).The CSR in general hospi⁃tals was higher than that in MCH(54.54% vs. 43.81%,P<0.01).The CS without medical indications or for social reasons accounted for 25.15% of all CS,while the scar uterus(36.31%),maternal pregnancy-related complications(13.17%)and abnormal fetal head position(6.33%)were the three leading medical indications of CS.CONCLUSION:The CSR in Shang⁃hai is at a high level.There are significant differences in CSR among different hospitals.The scar uterine and social rea⁃sons are the leading causes of CS in Shanghai.

Background::Previous studies have demonstrated that various circular RNAs are involved in the malignant proliferation of cancers, such as liver cancer, lung cancer, breast cancer, and others. The potential role of circular RNAs in glioblastoma, however, is still uncertain. In this study, we aimed to study the potential role of hsa_circ _01844 in glioblastoma.Methods::Using reverse transcription-polymerase chain reaction (RT-PCR) method, hsa_circ_01844 expression was measured in five glioblastoma samples and five normal brain samples. To evaluate the potential function of hsa_circ_01844 in glioblastoma, hsa_circ_01844 was overexpressed in glioblastoma cell lines (U251 and U87 cells). Using these two cell lines, in vitro experiments including the flow cytometry assay, 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay, Transwell assay, and cell apoptosis assay were performed to investigate the role of hsa_circ_01844 in glioblastoma. Student t test and one-way analysis of variance were used for statistical analysis. Results::The expression of circular RNA hsa_circ_01844 was lower in glioblastoma tissues when compared with the normal brain tissues by RT-PCR method (0.034 ± 0.036 vs. 1.630 ± 0.891, P < 0.001). Using two glioblastoma cell lines, we found that overexpression of hsa_circ_01844 in glioblastoma cells suppressed their proliferation, colony formation, migration, and increased the apoptotic rate compared with empty vector group and blank control group (all P < 0.05). Conclusion::Hsa_circ_01844 shows decreased expression in glioblastoma and its overexpression induces apoptosis and inhibits proliferation, migration, and invasion of glioblastoma cells.

Objective To investigate the risk factors of hip osteoarthritis(HOA)after hip arthroscopy in patients with femoro-acetabular impingement(FAI)syndrome,and to reduce and prevent HOA.Methods From September 2018 to Septem-ber 2020,106 patients with FAI underwent hip arthroscopy,including 40 males and 66 females,aged from 20 to 55 years old with an average age of(33.05±10.19)years old.The mechanism of injury included 51 cases for sports injury,36 for traffic ac-cidents,and 19 for blunt object injury.The duration of the disease ranged from 5 to 19 days with an average of(12.02±3.69)days.All patients were followed up for 18 months.Patients were divided into HOA group(23 cases)and non-HOA group(83 cases)according to the occurrence of HOA.Multivariate Logistic regression was used to analyze the risk factors of HOA after hip arthroscopy in FAI patients.Results By univariate analysis,aged from 50 to 70 years old,female,body mass index(BMI)＞30 kg·m-2,physical labor,cam type,postoperative infection,last follow-up hip degree of motion(range of motion,ROM)(flex-ion,abduction,adduction,internal rotation)and T?nnis grade 1 and above of the HOA group were higher than those of the non-HOA group(P＜0.05),and the relative appendicular skeletal muscle index(RASM)was lower than that of non-HOA group(P＜0.05).By multiple Logistic regression analysis,cam type,BMI＞30 kg·m-2,last follow-up hip internal rotation ROM and T?nnis grade 1 were risk factors for HOA after hip arthroscopy in FAI patients(P＜0.05).Conclusion FAI classification,body mass index,hip ROM and T?nnis grade are all related to HOA after hip arthroscopy in FAI patients.Follow-up and intervention should be strengthened in high-risk FAI patients to reduce the occurrence of HOA.

Poly (ADP-ribose) polymerase-1 (PARP-1) inhibitors and histone deacetylase (HDAC) inhibitors have recently emerged as promising anticancer drugs. The aim of this study was to investigate the effect of combination treatment with the PARP inhibitor PJ34 and HDAC inhibitor SAHA on the proliferation of liver cancer cells. Cell proliferation and apoptosis were assessed in three human liver cancer cell lines (HepG2, Hep3B and HCC-LM3) treated with PJ34 (8 μmol/L) and SAHA (1 μmol/L), alone or combined, by Cell Counting Kit-8 assay and flow cytometry, respectively. The nude mice bearing subcutaneous HepG2 tumors were administered different groups of drugs (10 mg/kg PJ34, 25 mg/kg SAHA, 10 mg/kg PJ34+25 mg/kg SAHA), and the inhibition rates of tumor growth were compared between groups. The results showed that combined use of PJ34 and SAHA could synergistically inhibit the proliferation of liver cancer cell lines HepG2, Hep3B and HCC-LM3. The apoptosis rate of HepG2 cells treated with PJ34+SAHA was significantly higher than that of HepG2 cells treated with PJ34 or SAHA alone (P<0.05). In vivo, the tumor inhibition rates were 53.5%, 61.4% and 82.6% in PJ34, SAHA and PJ34+SAHA groups, respectively. The combined use of PJ34 and SAHA could significantly inhibit the xenograft tumor growth when compared with use of PJ34 or SAHA alone (P<0.05). It was led to conclude that PJ34 and SAHA can synergistically suppress the proliferation of liver cancer cells.

Objectives: To investigate the association between acquired thrombocytopenia and long-term clinical outcome among stable coronary artery disease patients undergoing elective percutaneous coronary intervention (PCI). Methods: We analyzed clinical data of 8 271 consecutive patients who underwent elective PCI in Fuwai Hospital from January 2013 to December 2013. Acquired thrombocytopenia was defined as platelet count <150×109/L after PCI in patients with normal baseline platelet count value. We compared data on demographic, clinical, laboratory, and 30-month outcome between non-thrombocytopenic and thrombocytopenic patients and identified the independent predictors of acquired thrombocytopenia post PCI. Results: Acquired thrombocytopenia developed in 654 (7.91%) patients (634 [7.67%] patients had mild thrombocytopenia, 20 [0.24%] patients had moderate or severe thrombocytopenia). Patients who developed thrombocytopenia had higher 30-month rate of all cause death (2.3% vs 1.0%, P=0.0086) and cardiogenic death (1.2% vs 0.5%, P=0.0261). Moderate or severe thrombocytopenia was associated with a 13-fold increased risk for cardiogenic death, 7-fold increased risk for stent thrombosis,11-fold increased risk for myocardial infarction compared with patients without thrombocytopenia. Conclusions: Acquired thrombocytopenia after PCI is common in stable coronary artery disease patients and is independently associated with increased risk of long-term adverse outcome in these patients.

Objective To observe the safety and effectiveness of single dose intravenous infusion of tranexamic acid(TX-A)in dual level posterior lumbar interbody fusion(PLIF),and to explore the changes and trends in perioperative white blood cell(WBC),erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP).Methods Between October 2020 and September 2022,46 patients with lumbar degenerative disease were treated with dual level PLIF,including 18 males and 28 females,with an average age of(60.24±10.68)years old,from 34 to 80 years old.They were divided into observation group and control group according to different treatment methods.There were 28 patients in the observation group,including 12 males and 16 females,with an average age of(61.04±9.03)years old.There were 3 cases with lumbar disc herniation(LDH),lumbar spinal stenosis(LSS)18 cases,lumbar spondylolisthesis(LS)7 cases.TXA(1 g/100 ml)was administered intravenously 15 min before skin incision after general anesthesia.The control group consisted of 18 patients,including 6 males and 12 females,with an average age of(59.00±13.04)years old.There were 5 cases with LDH,LSS 9 cases,LS 4 cases,and TXA was not used.The operation time,intraoperative bleeding volume,postoperative drainage volume,postoperative deep vein thrombosis(DVT),postoperative hospital stay,postoperative activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB),platelet(PLT),red blood cell(RBC),hemoglobin(HB),hematocrit(HCT),the first day,the fourth day,the seventh day and the last tested after operation WBC,ESR and CRP were recorded.Results The postop-erative wounds of the patients healed well and there was no DVT.46 patients were followed up from 3 to 6 months.The intraop-erative blood loss was 400.0(300.0,500.0)ml and the postoperative drainage was 260.0(220.0,450.0)ml in the observation group,which were lower than the control group[600.0(400.0,1000.0)ml,395.0(300.0,450.0)ml],P＜0.05.There was no significant difference between the two groups in operation time,postoperative hospital stay,postoperative APTT,PT,TT,FIB,PLT,RBC,HB,HCT,and postoperative WBC,ESR and CRP at different times(P＞0.05).Conclusion Single dose intravenous infusion of TXA can reduce the blood loss of bi-segmental PLIF,and has no significant effect on WBC,ESR and CRP after op-eration.
