BACKGROUND: Reports on the prevalence of psoriatic arthritis (PsA) among Chinese patients with psoriasis are very limited. This study, conducted by rheumatologists, estimated the prevalence of PsA in a large number of Chinese patients with psoriasis. METHODS: Consecutive patients with a confirmed diagnosis of psoriasis attending nine dermatology clinics in five hospitals were recruited. All psoriasis patients were asked to complete a questionnaire comprising 16 questions to identify possible cases of PsA. All patients with one or more positive answers to the questionnaire were evaluated by two experienced rheumatologists. RESULTS: A total of 2434 psoriasis patients, including 1561 males and 873 females, were enrolled. Both the questionnaire and rheumatologists' examinations were completed in the dermatology clinics. The results identified 252 patients with PsA, comprising 168 males and 84 females. The overall prevalence of PsA among psoriasis patients was 10.4% (95% confidence interval [95% CI], 9.1%-11.7%). By sex, the prevalence was 10.8% (95% CI, 9.2%-12.5%) for males and 9.6% (95% CI, 7.7%-11.9%) for females and there was no significant sex difference in the prevalence of PsA (P = 0.38). Of the 252 PsA patients, 125 (49.6%, 95% CI, 41.3%-59.1%) were newly diagnosed by rheumatologists. Consequently, the prevalence of undiagnosed PsA among psoriasis patients was 5.2% (95% CI, 4.4%-6.2%). CONCLUSION The prevalence of PsA in the Chinese population with psoriasis is about 10.4%, which is almost double that of previous reports in the Chinese population, but lower than that in Caucasians.

Objective:To investigate the prognostic factors of patients with esophageal squamous cell carcinoma with pulmonary metastasis.Methods:Clinical characteristics of 135 esophageal squamous cell carcinoma patients presenting with pulmonary metastasis after treatment in Zhejiang Cancer Hospital from 2008 to 2018 were retrospectively analyzed. Thesurvival rate was calculated by Kaplan-Meier method. Univariate analysis was performed by log-rank test. Multivariate prognostic analysis was conducted by Cox models.Results:The median follow-up time of 135 patients with esophageal squamous cell carcinoma was 94.2 months (19.5-258.9 months), and 109 patients died (80.7%). The 1-and 2-year overall survival rates were 47.4% and 25.1%, with the median survival time was 11.1 months (7.3-14.9 months). Univariate prognostic analysis showed that age, number of lung metastases, treatment of lung metastases, lymph node metastasis, distant organ metastasis, and the interval between the first treatment and lung metastasis were the prognostic factors of esophageal squamous cell carcinoma with lung metastasis (all P<0.05). Multivariate analysis demonstrated that age and number of lung metastases were the independent prognostic factors for patients with esophageal squamous cell carcinoma with lung metastases (all P<0.05). Conclusions:Age and number of lung metastases are the independent prognostic factors for patients with esophageal squamous cell carcinoma with lung metastases. Surgery or radiotherapy-based regional therapy can enhance clinical prognosis.

Angiotensin (Ang)-(1-7) is an important biologically-active peptide of the renin-angiotensin system. This study was designed to determine whether inhibition of Ang-(1-7) in the hypothalamic paraventricular nucleus (PVN) attenuates sympathetic activity and elevates blood pressure by modulating pro-inflammatory cytokines (PICs) and oxidative stress in the PVN in salt-induced hypertension. Rats were fed either a high-salt (8% NaCl) or a normal salt diet (0.3% NaCl) for 10 weeks, followed by bilateral microinjections of the Ang-(1-7) antagonist A-779 or vehicle into the PVN. We found that the mean arterial pressure (MAP), renal sympathetic nerve activity (RSNA), and plasma norepinephrine (NE) were significantly increased in salt-induced hypertensive rats. The high-salt diet also resulted in higher levels of the PICs interleukin-6, interleukin-1beta, tumor necrosis factor alpha, and monocyte chemotactic protein-1, as well as higher gp91 expression and superoxide production in the PVN. Microinjection of A-779 (3 nmol/50 nL) into the bilateral PVN of hypertensive rats not only attenuated MAP, RSNA, and NE, but also decreased the PICs and oxidative stress in the PVN. These results suggest that the increased MAP and sympathetic activity in salt-induced hypertension can be suppressed by blockade of endogenous Ang-(1-7) in the PVN, through modulation of PICs and oxidative stress.

BACKGROUNDEpstein-Barr virus (EBV) commonly infects the general population and has been associated with nasopharyngeal carcinoma (NPC), which has a high incidence in certain regions. This study aimed to address how EBV variations contribute to the risk of NPC.

METHODSUsing logistic regression analysis and based on the sequence variations at EBV-encoded RPMS1, a multi-stage association study was conducted to identify EBV variations associated with NPC risk. A protein degradation assay was performed to characterize the functional relevance of the RPMS1 variations.

RESULTSBased on EBV-encoded RPMS1 variations, a single nucleotide polymorphism (SNP) in the EBV genome (locus 155391: G>A, named G155391A) was associated with NPC in 157 cases and 319 healthy controls from an NPC endemic region in South China [P < 0.001, odds ratio (OR) = 4.47, 95% confidence interval (CI) 2.71-7.37]. The results were further validated in three independent cohorts from the NPC endemic region (P < 0.001, OR = 5.20, 95% CI 3.18-8.50 in 168 cases vs. 241 controls, and P < 0.001, OR = 5.27, 95% CI 4.06-6.85 in 726 cases vs. 880 controls) and a non-endemic region (P < 0.001, OR = 7.52, 95% CI 3.69-15.32 in 58 cases vs. 612 controls). The combined analysis in 1109 cases and 2052 controls revealed that the SNP G155391A was strongly associated with NPC (P(combined) < 0.001, OR = 5.27, 95% CI 4.31-6.44). Moreover, the frequency of the SNP G155391A was associated with NPC incidence but was not associated with the incidences of other EBV-related malignancies. Furthermore, the protein degradation assay showed that this SNP decreased the degradation of the oncogenic RPMS1 protein.

CONCLUSIONSOur study identified an EBV variation specifically and significantly associated with a high risk of NPC. These findings provide insights into the pathogenesis of NPC and strategies for prevention.

BACKGROUNDRecombinant human parathyroid hormone (1-34) (rhPTH (1-34)) is the first agent in a unique class of anabolic therapies acting on the skeleton. The efficacy and safety of long-term administration of rhPTH (1-34) in Chinese postmenopausal women had not been evaluated. This study compared the clinical efficacy and safety of rhPTH (1-34) with elcatonin for treating postmenopausal women with osteoporosis in 11 urban areas of China.

METHODSA total of 453 postmenopausal women with osteoporosis were enrolled in an 18-month, multi-center, randomized, controlled study. They were randomized to receive either rhPTH (1-34) 20 µg (200 U) daily for 18 months, or elcatonin 20 U weekly for 12 months. Lumbar spine (L1-4) and femoral neck bone mineral density (BMD), fracture rate, back pain as well as biochemical markers of bone turnover were measured. Adverse events were recorded.

RESULTSrhPTH (1-34) increased lumbar BMD significantly more than did elcatonin after 6, 12, and 18 months of treatment (4.3% vs. 1.9%, 6.8% vs. 2.7%, 9.5% vs. 2.9%, P < 0.01). There was only a small but significant increase of femoral neck BMD after 18 months (2.6%, P < 0.01) in rhPTH groups. There were larger increases in bone turnover markers in the rhPTH (1-34) group than those in the elcatonin group after 6, 12, and 18 months (serum bone-specific alkaline phosphatase (BSAP) 93.7% vs. -3.6%; 117.8% vs. -4.1%; 49.2% vs. -5.8%, P < 0.01; urinary C-telopeptide/creatinine (CTX/Cr) 250.0% vs. -29.5%; 330.0% vs. -41.4%, 273.0% vs. -10.6%, P < 0.01). rhPTH (1-34) showed similar effect of pain relief as elcatonin. The incidence of clinical fractures was 5.36% (6/112) in elcatonin group and 3.2% (11/341) in rhPTH (1-34) group (P = 0.303). Both treatments were well tolerated. Hypercaluria (9.4%) and hypercalcemia (7.0%) in rhPTH (1-34) group were transient and caused no clinical symptoms. Pruritus (8.2% vs. 2.7%, P = 0.044) and redness of injection site (4.4% vs. 0, P = 0.024) were more frequent in rhPTH (1-34). Nausea/vomiting (16.1% vs. 6.2%, P = 0.001) and hot flushes (7.1% vs. 0.6%, P < 0.001) were more common in elcatonin group.

CONCLUSIONSrhPTH (1-34) was associated with greater increases in lumbar spine BMD and bone formation markers. It could increase femoral BMD after 18 months of treatment. rhPTH could improve back pain effectively. The results of the present study indicate that rhPTH (1-34) is an effective, safe agent in treating Chinese postmenopausal women with osteoporosis.

OBJECTIVE: To investigate the intestinal absorption behaviors of Diospyros kaki L.f. extract (PLE) in self-microemulsifying drug delivery system (SMEDDS). METHODS: The concentration of quercetin, kaempferol and phenol red in rat intestinal perfusion solution was determined by HPLC. Rat single-pass intestinal perfusion technique was employed to assay the effects of concentrations of PLE in perfusion solution, intestinal segments and different formulations on the drug percentage absorbed (P) and the absorption rate constant (Ka). RESULTS: No significant changes of Ka and P were observed in different PLE concentrations. The main absorption segments of SMEDDS in rat intestines were the duodenum and ileum. The values of Ka and P of SMEDDS were significantly higher than the PLE solution (P<0.05). CONCLUSION: The absorption mechanism of PLE conforms to passive diffusion. The PLE SMEDDS presented the high absorption rate than conventional solution in rat intestine, which illustrates the potential use of SMEDDS for the delivery o f PLE by the oral route.

BACKGROUNDRadiofrequency (RF) ablation has become a widely accepted treatment for atrial fibrillation (AF). This study aimed to identify the efficacy and safety of pulmonary vein (PV) ablation with ethanol and to explore an alternative energy source for catheter ablation of AF.

METHODSTwelve open-chest mongrel dogs were randomized into ethanol ablation group and control group. Both the injections and electrophysiological mapping procedures were performed epicardialy. In ethanol ablation group (n = 6), injections were performed to circumferentially ablate the root of each PV (0.2 ml each site, 3 mm apart) with 95% ethanol using an 1 ml injector. In control group (n = 6), saline was injected other than ethanol. PV isolation was confirmed with a circular catheter immediately after the procedure and at follow up of 30 days. PV isolation was defined as the absence of PV potentials at each electrode of the circular catheter positioned at the PV side of the lesions, as well as complete conduction block into left atrium (LA) during PV pacing.

RESULTSPV electrical isolation with complete bidirectional conduction block was achieved with ethanol immediately and at 30 days in 95% of PVs, while saline injection caused only transient conduction changes between LA and PVs. In ethanol group, histologic analysis showed transmural lesions at 30 days. And there was no evidence of PV stenosis or thrombus formation. Mean LA diameter was not significantly different between baseline and 30 days.

CONCLUSIONEthanol is a safe energy source to effectively isolate PV in canine model and may be promising in endocardial ablation procedure of AF patients in the future.
