【Objective】 To investigate the expression profile of circRNA in nuclear receptor NURR1 overexpressed prostate cancer (PCa) cells, so as to provide reference for revealing the mechanism of PCa progression. 【Methods】 The expression of NURR1 in PCa was analyzed with UALCAN and TNMplot. The distinct circRNAs in NURR1 overexpressed PCa cells were screened with RNA-sequencing. The functions and signal pathways of differentially expressed circRNA molecules were analyzed with GO and KEGG. 【Results】 The circ_0000915 was significantly downregulated in DU145, LNCaP and PC3 cells. In NURR1 overexpressed DU145 cells, circ_0005991 was up-regulated, while circ_0001460 and circ_0001315 were down-regulated. In NURR1 overexpressed LNCaP cells, circ_0040729 and circ_0000722 were significantly up-regulated. In NURR1 overexpressed PC3 cells, circ_0001577, circ_0000854 and circ_0018168 were up-regulated, while circ_013035, circ_0003028, circ_0082096 and circ_0005320 were down-regulated. KEGG analysis revealed that the differentially expressed circRNAs were significantly associated with dorsal/ventral neural tube patterns, protein folding chaperones, disordered domain specific binding, positive regulation of BMP signaling pathways, and neural tube patterning functions. 【Conclusion】 CircRNAs play an important role in NURR1 mediated PCa progression, but there are certain differences among different prostate cancer cell types. The regulatory mechanism between NURR1 and circ_0000915 in the progression of PCa needs further investigation.

Mayaro fever is a mosquito-borne viral infectious disease caused by Mayaro virus (MAYV). The main clinical symptoms are sudden onset of high fever triad, arthralgia and maculopapular rash. MAYV outbreaks occur more frequently in the Americas Region, particularly within tropical forests in Brazil. However, in recent years, virus circulation has been spreading to the Switzerland and Netherlands in Europe, which may invade urban areas and cause epidemics across the region. Consequently, this work focuses on the epidemiological characteristics and research progress of MAYV prevention and control, including biological characteristics, epidemiology, transmission vectors, prevention measures and treatment of this virus.

Objective:To explore the locations of the lumbosacral nerve roots by use of the magnetic stimulation.Methods:Thirty healthy subjects were studied. The projections of the right L 2 to S 1 intervertebral foramina on their body surfaces were determined manually with ultrasound assistance. Magnetic stimulation was applied to different nerve root segments to induce compound muscle action potentials (CMAP) in the vastus medialis, tibialis anterior, and gastrocnemius muscles of the lower limbs. The changes in latency, amplitude, and motor threshold were observed. Results:Magnetic stimulation on the L 2-L 3 segment resulted in a significant direct excitation of the vastus medialis. That on the L 5-S 1 segment evoked a significant direct excitatory effect on the tibialis anterior and gastrocnemius, with a motor threshold below 40%, an amplitude exceeding 1mV, and many effective responses. However, during the magnetic stimulation on the L 4 segment, the amplitude of the vastus medialis was above 1mV, with no significant differences in the number of effective responses among the muscle groups. Moreover, there was a stepwise change in the latency of effective muscle responses to magnetic stimulation at different segments. The CMAP latencies of 12+ ms for the tibialis anterior and 13+ ms for the gastrocnemius indicated activation of the L 5 and L 4 nerve roots, respectively, while those of 6+ ms, 7+ ms, and 8+ ms for the vastus medialis suggested activation of the L 4, L 3, and L 2 nerve roots, respectively. Conclusions:Based on the responses (CMAP latency, amplitude and motor threshold) of the vastus medialis, tibialis anterior and gastrocnemius to magnetic stimulation at different L 2 to S 1 segments, the spinal nerve root segments responsible for innervation can be inferred.

Objective:To investigate the clinical characteristics, diagnosis and treatment of chronic natural killer cell lymphoproliferative disease (CLPD-NK) associated peripheral neuropathy.Methods:The clinical data of 1 case of CLPD-NK associated peripheral neuropathy who was hospitalized in Beijing Chaoyang Hospital on March 17, 2022 were reported. The clinical characteristics, laboratory examinations, nerve biopsy, treatment and prognosis of CLPD-NK associated peripheral neuropathy were summarized in combination with domestic and foreign literature reports.Results:This patient was a 62-year-old woman with progressive weakness and numbness of limbs. Nerve conduction test revealed peripheral nerves injures of limbs. No abnormality was found in a routine biochemistry test of cerebrospinal fluid. Lymphocyte infiltration was found in the nerve bundle of sural nerve with CD56(+), TIA-1(+). After prednisone combined with cyclophosphamide treatment, her weakness and numbness of limbs were relieved, and the white blood cells count decreased. A total of 10 cases of CLPD-NK associated peripheral neuropathy were summarized, including 5 males and 5 females. The median onset age was 64 years. The peripheral blood white cells count was 5.50×10 9/L-24.66×10 9/L, the lymphocytes count was 1.54×10 9/L-32.00×10 9/L, and cerebrospinal fluid protein increased in 3 cases. Biopsy of sural nerve showed NK cell infiltration in all patients. Immunosuppression was the main treatment, and most patients had a good prognosis. Conclusions:CLPD-NK associated peripheral neuropathy is rare. Peripheral nerve biopsy is the important diagnostic method. Corticosteroids and immunosuppressants are effective for this disease.

Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population. Methods We conducted a retrospective observational study to investigate the relationship between lipid markers [including triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL-cholesterol, apolipoprotein A-I, apolipoprotein B, lipoprotein[a], and composite lipid profiles] and left ventricular hypertrophy. A total of 309,400 participants of two populations (one from Beijing and another from nationwide) who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study. 7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy. Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the interventricular septum or left ventricle posterior wall > 11 mm. The Logistic regression model was used in the cross-sectional study. Cox model and Cox model with restricted cubic splines were used in the longitudinal cohort. Results In the cross-sectional study, for participants in the highest tertile of each lipid marker compared to the respective lowest, triglycerides [odds ratio (OR): 1.250, 95%CI: 1.060 to 1.474], HDL-cholesterol (OR: 0.780, 95%CI: 0.662 to 0.918), and lipoprotein(a) (OR: 1.311, 95%CI: 1.115 to 1.541) had an association with left ventricular hypertrophy. In the longitudinal cohort, for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest, triglycerides [hazard ratio (HR): 3.277, 95%CI: 1.720 to 6.244], HDL-cholesterol (HR: 0.516, 95%CI: 0.283 to 0.940), non-HDL-cholesterol (HR: 2.309, 95%CI: 1.296 to 4.112), apolipoprotein B (HR: 2.244, 95%CI: 1.251 to 4.032) showed an association with new-onset left ventricular hypertrophy. In the Cox model with forward stepwise selection, triglycerides were the only lipid markers entered into the final model. Conclusion Lipids levels, especially triglycerides, are associated with left ventricular hypertrophy. Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be further investigated.

Objective:To assess the effect of patient-controlled intravenous analgesia (PCIA) with different postoperative analgesics on prognosis after colorectal surgery. Methods:A total of 460 colorectal cancer patients (TNMⅠ-Ⅱ) who underwent elective surgery within January 2010 to December 2012 in Chongqing Cancer Hospital were randomly divided into five groups for PCIA with sufentanil, dezocine, butorphanol, morphine, and tramadol. We evaluated the analgesic efficacy, detected NK cell activity and Th1/Th2 ratio from peripheral blood, and observed short-term complications and long-term cancer recurrence and metastasis. Healthy volunteers served as the control group. Results:The morphine group displayed a VAS score of less than 3 in the rest state and showed the longest hospital stay and the highest incidence of pruritus (P<0.05). The incidence of postoperative nausea and vomiting was the highest in the tramadol group (P<0.05). NK cel activity and Th1/Th2 ratio decreased in al experimental groups after surgery. NK activity and Th1/Th2 ratio returned to the control level 7 days after surgery in the tramadol and sulfentanil groups and 14 days after surgery in the dezocine and butorphanol groups (P>0.05), whereas those in the morphine group remained low (P<0.05). The incidences of cancer recurrence and metastasis were ranked as follows:morphine>butorphnol>dezocine>sufentanil>tramadol. Conclusion:Tramadol and sufentanil used in PCIA after colorectal surgery could facilitate the recovery of immune function and reduced the incidence of recurrence and metastasis.
