OBJECTIVE: To determine the prevalence of depression and anxiety in patients with psoriatic arthritis (PsA), to investigate whether there is a difference in the prevalence of depression and anxiety between PsA and rheumatoid arthritis (RA) patients and to identify associated risk factors for depression and anxiety in PsA patients. METHODS: PsA and RA patients who visited Department of Rheumatology and Clinical Immunology in Peking University First Hospital from May 2018 to Sep 2019 were recruited. Self-rating anxiety scale and self-rating depression scale were surveyed and compared between PsA and RA patients. Demographics and clinical features including age, gender, disease duration, disease activity score, psoriasis area and severity index (PASI), and medical application were collected. Power Doppler and grey-scale ultrasound of joints, tenosynovitis and enthesis were performed. Multivariate Logistic regression was used to identify the factors associated with mood disorders and the odds ratio of depression and anxiety between the PsA and RA patients. RESULTS: Among the 114 enrolled PsA patients, 37 (32.5%) had mood disorders, in which 36 (31.6%) with depression and 15 (13.2%) with anxiety. Compared with 201 RA patients, PsA patients showed greater odds for depression [adjusted OR (95%CI): 2.7 (1.1-6.4)]. Depression was more often observed in the PsA than in the RA patients (31.6% vs. 18.9%, P=0.011). The similar trend for anxiety was also observed, although the difference was insignificant (13.2% vs. 8.5%, P=0.185). Age (OR=0.95, P=0.008), psoriasis duration (OR=0.94, P=0.018), pain visual analogue scale (OR=1.47, P=0.011), PASI score (OR=1.07, P=0.007) and presence of ultrasound enthesitis (OR=4.13, P=0.009) were identified as factors associated with depression in the PsA patients. PASI score (OR=1.07, P=0.001) was identified as associated factor for anxiety in the PsA patients. CONCLUSION The prevalence of depression and anxiety is elevated in PsA patients. Depression is significantly more prevalent in PsA patients than in RA patients. Younger age, shorter psoriasis duration, worse pain and presence of ultrasound enthesitis are associated with depression, while severe psoriasis rash is associated with both depression and anxiety in PsA patients.

OBJECTIVETo compare the clinical effectiveness of blind intubation through the Cookgas intubating laryngeal airway(CILA) or Fastrach intubating laryngeal mask airway(FT-LMA) for anticipated difficult tracheal intubation.

METHODSEighty-six patients with anticipated difficult tracheal intubation who were undergoing elective plastic surgery under general anesthesia were randomly allocated into CILA group(n=43) and FT-LMA group(n=43) . After general anesthesia being induced and CILA or FT-LMA being inserted, the patients were treated with blind intubation through CILA or FT-LMA. In each case, the number and the time of intubating laryngeal airway(ILA) insertion and blind intubation attempts and ILA removal were recorded. The view of glottis under fiberoptic bronchoscope(FOB) via CILA or FT-LMA was recorded. In addition, noninvasive blood pressure and heart rate were recorded before and after intravenous anesthetic induction, at ILA insertion, at intubation, at ILA removal and every minute thereafter for 5 minutes.

RESULTSCILA or FT-LMA was inserted successfully in all 86 patients. The rate of the first successful insertion was not significantly different between two groups(P>0.05) . In CILA group, the first intubation attempt succeeded in 35 patients;5 and 2 cases were intubated blindly at the second and the third attempt, one patient failed who was intubated successfully by FOB via CILA. In FT-LMA group, 32 patients were intubated successfully at the first attempt, 4 at the second attempt, 3 at the third attempt, and 4 cases failed, three of them were intubated smoothly with FOB through FT-LMA, one failed patient was intubated by FOB. The time of FT-LMA insertion(34.2∓13.9) s was significantly longer when compared with CILA(22.4∓18.9) s (P<0.05) . However, the time of blind intubation through CILA and FT-LMA [(46.0∓26.7) s vs.(51.8∓41.1) s]and the time of ILA removal[(39.3∓11.9) s vs.(35.3∓10.4) s] were not significantly different between groups(P>0.05) . Hemodynamic changes during blind intubation in the two groups showed no significant differences(P>0.05) .

CONCLUSIONSBlind intubation via CILA or FT-LMA is safe and effective for anticipated difficult tracheal intubation. Nevertheless, CILA is easier to be inserted, with relatively higher success rate of blind intubation.

Objective To study the anatomical classification and surgical management of communicating tumors invading the anterior or middle skull base. Methods According to the location and growth direction of the tumors, the communicating tumors invading the anterior or middle skull base in 29 patients were classified into 4 types, namely fronto-naso-orbital tumors in 16 cases, middle-lateral cranial base tumors in 8 cases, central-medial skull base tumors in 4 cases and petrous bone-jugular foramen tumor in 1 case. Based on this classification, extended transbasal approach (13 cases), supraorbital-pterional approach (9 cases), fronto-temporal approach (3 cases), ffontotemporal-orbitozygomatic approach (3 cases) and transpetrol approach (1 case) were adopted for tumor resection and skull base defect reconstruction. In the transbasal approach group, the surgery was performed also through transnasal endoscopic approaches. Results Twenty-four patients underwent total tumor resection and 5 had subtotal tumor resection. No operative death or serious complications (e.g. intracranial infection, cerebrospinal fluid leakage or meningoencephalocele) occurred after the operations. Conclusion Classification of the communicating tumors invading the anterior or middle skull base according to their location and growth direction facilitates planning of the surgical approaches for tumor resection and skull base defect reconstruction.

OBJECTIVETo observe the effectiveness of conscious sedation with midazolam, propofol and sufentanil for patients in plastic surgery.

METHODS81 patients, scheduled for plastic surgery, were randomly selected to receive conscious sedation with midazolam 0.05 mg x kg(-1) and sufentanil 0.1 microg x kg(-1) intravenously, following by a continuous infusion of midazolam-propofol-sufentanil combination (midazolam 5 mg + propofol 200 mg + sufentanil 10 microg, a total of 23 ml). The initial infusion rate was 0.2 ml x kg(-1) x h(-1), and was adjusted (in 20% of initial infusion rate increment) to maintain OAA/S score as 11 during the operation. The patients' vital signs, discomfort and level of sedation were evaluated at 5 to 10 min intervals until the end of the surgery. The complications (i. e. anoxemia, apnea, restlessness, nausea and vomiting), anesthesia duration and drug consumption were recorded. The drug infusion was discontinued at 5 - 10 min before the end of the surgical procedure. On the first postoperative day, patients were asked to rate their satisfaction with the anesthetic management and whether they would choose to receive the same anesthetic technique if necessary in the future.

RESULTSThe OAA/S score decreased from 20.0 +/- 0 to 11.9 +/- 2.6 after midazolam and sufentanil IV (P < 0.05), and was maintained as 10.5-11.1 during the procedure. At the end of the procedure, the OAA/S score returned to 16.0 +/- 2.2, which was also lower significantly compared with baseline value (P < 0.05). The induction of sedation produced a significant decrease in SBP and DBP (P < 0.05) and no significant changes in heart rate (P > 0.05). At the end of the procedure, SBP, DBP and HR returned to the baseline value. The anoxemia happened in 11 cases, apnea in 5 cases and restlessness in 2. No nausea and vomiting occurred. The anesthesia duration and consumption of midazolam, propofol and sufentanil were (101.1 +/- 42.5) min, (8.4 +/- 3.7) mg, (189.1 +/- 88.7) mg and (18.2 +/- 5.6) microg respectively. In an interview on the first postoperative day, 96% (78/ 81) of the patients were satisfied with their anesthesia and were willing to receive the same anesthetic technique if necessary in the future.

CONCLUSIONConscious sedation with midazolam, propofol and sufentanil is an effective anesthetic technique for patients in plastic surgery.

BACKGROUNDSome larger scale, randomized studies have demonstrated the superiority of drug-eluting stents (DES) over bare metal stents (BMS) for the treatment of acute myocardial infarction (AMI). This study aimed to investigate the impact of DES, in comparison with BMS, on the 2-year clinical outcomes in patients with ST-elevation myocardial infarction (STEMI).

METHODSFrom January 2002 to December 2008, a total of 1301 consecutive STEMI patients treated with coronary stenting in Shenyang Northern Hospital were prospectively registered. Patients received BMS (n = 868) or DES (n = 435) implantation in the infarction related artery according to physician's discretion. A propensity score analysis was performed and two well matched subgroups were selected (BMS, n = 288; DES, n = 288) to evaluate the 2-year clinical outcomes. The primary outcome was the occurrence of major adverse cardiac events (MACE), which was defined as a composite of all-cause death, myocardial infarction (MI), or target vessel revascularization (TVR).

RESULTSSurvival salvage analysis showed that 2-year cumulative hazards were not significantly different between the two groups with respect to TVR (2.8% vs. 3.1%, log-rank P = 0.780), stent thrombosis (1.7% vs. 4.2%, log-rank P = 0.079) and MACE (8% vs. 10.8%, log-rank P = 0.236). Multivariate analysis showed that DES was an independent protective factor of MI (HR: 0.211, 95%CI: 0.049 to 0.908) and stent thrombosis (HR: 0.327, 95%CI: 0.107 to 0.994).

CONCLUSIONDES was associated with similar 2-year clinical outcomes to those of BMS for the treatment of STEMI in daily practice.

OBJECTIVETo study the role of a pathologic niche inducing mouse embryonic stem cells (ESC) to express hepatic cell functions in vitro.

METHODSEmbryoid bodies were developed from 5 to 7 day hanging-drop culture of mouse ESC, and their dissociated cells were planted in three differential systems: nothing added; with 20 ng/ml hepatocyte growth factor (HGF); and 5% rat cholestatic serum plus 20 ng/ml HGF added. Their differentiation was observed with inverted microscopes daily, and their hepatic functions were analyzed against their synthesis of glycogen, triglycerides, albumin, and urea nitrogen, and by their staining of indocyanine green (ICG) and fluorescein diacetate (FDA).

RESULTSESC spontaneous differentiation was hardly being controlled to form three germ layers. HGF prompted the ESC to develop further into visceral endoderm and mesoderm (myocardium), but both of them only expressed a low level of hepatocyte-specific metabolic functions. With cholestatic serum added into the HGF-induced system, differentiated cells grew into similar angular cells, and had a higher level synthesis of glycogen, triglycerides, albumin and urea nitrogen with positive ICG and FDA staining.

CONCLUSIONSSpontaneous or HGF-induced ESC differentiation has only limited hepatic functions expressed. A pathologic niche in vitro induces ESC to develop into hepatic lineages, with a higher level of hepatic metabolic functions.

BACKGROUNDTo investigate the incidence and risk factors of retinopathy of prematurity (ROP) in two Neonatal Intensive Care Units in North and South of China, respectively.

METHODSWe studied data concerning 472 infants with gestational age (GA) ≤ 34 weeks or birth weight (BW) ≤ 2000 g who were admitted to the Zhujiang Hospital of Southern Medical University and the Fourth Hospital of Shijiazhuang between January 1, 2011 and December 31, 2011. Clinical information about perinatal neonates was collected and was confirmed by reviewing medical charts. The incidence and severity of ROP were assessed in the screened population. Main outcome measures are the incidence and severity of ROP. The relationship of clinical risk factors and the development of ROP were analyzed.

RESULTSThe overall incidence of ROP was 12.7%, and the overall incidence of type 1 ROP was 2.3%; 9.4% of infants in Zhujiang Hospital had ROP compared to 15.0% infants in the Fourth Hospital of Shijiazhuang developed ROP, and the difference is statistically significant. ROP was significantly associated with GA (odds ratio [OR]: 0.77 [0.62-0.95], P = 0.015), BW (OR: 0.998 [0.996-0.999], P = 0.008), maternal supplemental oxygen administration before and during delivery (OR: 4.27 [1.21-15.10], P = 0.024) and preeclampsia (OR: 6.07 [1.73-21.36] P = 0.005). The risk factors for ROP are different in two hospitals. In Zhujiang Hospital, BW is the independent risk factors for ROP while GA, BW and preeclampsia in the Fourth Hospital in Shijiazhuang Conclusions: Retinopathy of prematurity incidence is different based on area. Incidence of ROP is still high in China. More efforts need to prevent ROP.

OBJECTIVETo observe the safety and feasibility of tracheal intubation by target-controlled infusion of propofol and remifentanil without muscle relaxant in children.

METHODSTotally 100 4-10-year-old pediatric patients (ASA1) who had been scheduled for plastic surgery were equally divided into remifentanil group and control group through computer-generated randomized grouping. In all patients, five minutes after intravenous administration of atropine 0.01 mg/kg and midazolam 0.1 mg/kg, propofol was infused at the targeted effect-site concentration (Ce of 6 μg/ml. When the intended target Ce of propofol was reached, the remifentanil group began to be infused with remifentanil at a Ce of 5 ng/ml, and normal saline (0.1 ml/kg) was injected simultaneously. In the control group remifentanil was replaced by normal saline and rocuronium (0.8 mg/kg) was injected together with the normal saline. After the equilibration of plasma and the Ce of remifentanil were reached, tracheal intubation was attempted. The complications during the induction and tracheal intubation were recorded. The intubating conditions were assessed using a five-point scoring system based on ease of laryngoscopy, vocal cords position, coughing, jaw relaxation and limb movement.

RESULTSThe success rate of tracheal intubation was in 90% in remifentanil group and 98% in the control group (P=0.122).CONCLUSION Target-controlled infusion of propofol and remifentanil at Ce of 6 μg/ml and 5 ng/ml is feasible for the induction and tracheal intubation without muscle relaxant in children.
