Objective: To examine the impact of heat waves and cold spells on the incidence of hemorrhagic stroke, so as to provide insights into prevention of hemorrhagic stroke. Methods: Data pertaining to the incidence of hemorrhagic stroke in Zibo City from 2015 to 2019 were collected from Shandong Provincial Management Information System for Chronic Diseases and Cause of Death Surveillance, and the meteorological data during the period from 2015 to 2019 were captured from National Meteorological Information Center of China. The air quality index (AQI) was collected from the National Daily Report of Urban Air Quality in China. Heat wave was defined as the highest daily temperature that was no less than the 90th percentile (P90), P92.5, P95 and P97.5 of the highest daily temperature in the warm season for at least 2, 3 or 4 days, and cold spell was defined as the lowest daily temperature that was no more than the P10, P7.5, P5 and P2.5 of the lowest daily temperature in the cold season for at least 2, 3 or 4 days. The effect of heat waves and cold spells on the incidence of hemorrhagic stroke was evaluated using a generalized additive model and described with relative risk (RR) and its 95%CI. Results: A total of 8 844 case with first-onset hemorrhagic stroke were recorded in Zibo City from 2015 to 2019. The lowest daily temperature that was no more than P10, P7.5 or P5 of the lowest daily temperature in the cold season for at least two days, or that was no more than P10 or P7.5 of the lowest daily temperature for at least 3 days resulted a remarkably increased risk of hemorrhagic stroke (lowest RR=1.187, 95%CI: 1.031-1.366; highest RR=1.242, 95%CI: 1.042-1.480), and after adjusting the effect of daily mean temperature, the lowest daily temperature that was no more than P10 or P7.5 of the lowest daily temperature in the cold season for at least two days, or that was no more than P10 of the lowest daily temperature for at least 3 days resulted a remarkably increased risk of hemorrhagic stroke (lowest RR=1.236, 95%CI: 1.009-1.513; highest RR=1.274, 95%CI: 1.023-1.585). However, there was no significant association between heat waves and the risk of hemorrhagic stroke. Conclusion Cold spells may increase the risk of hemorrhagic stroke, while no significant association is examined between heat waves and the risk of hemorrhagic stroke.

OBJECTIVETo investigate the clinicopathological characteristics between mucinous gastric cancer (MGC) and poorly differentiated gastric cancer(PDGC) and factors associated with prognosis.

METHODSMedical records of 1016 consecutive patients with gastric cancer were retrospectively reviewed. Sixty-eight patients with MGC and 508 with PDGC were identified. Clinicopathologic characteristics and overall survival data were analyzed.

RESULTSAs compared to PDGC patients, patients with MGC were significantly older [(59.2±11.9) years vs. (54.1±13.2) years], had significantly more distant metastasis(36.8% vs. 23.8%), more peritoneal seeding(29.4% vs. 16.9%), and less radical resection(60.3% vs. 76.6%). There were no significant differences in 5-year survival rate between MGC and PDGC patients(29.4% vs. 35.5%). However, for tumors in the middle third of the stomach, the survival rate of MGC patients was lower than that of PDGC. Using a Cox proportional hazard ratio model, lymph node involvement and radical resection were independent prognostic factors for survival of MGC patients, while tumor invasion, lymph node involvement, and radical resection were associated with survival in patients with PDGC.

CONCLUSIONAlthough MGC and PDGC differ in age, frequencies of peritoneal seeding, distant metastasis, and rate of radical resection, overall survival is comparable.

OBJECTIVETo investigate the role of silencing PRL-3 expression by miRNA interference in gastric cancer growth.

METHODSRNA interference mediated by recombinant lentivirus expressing artificial PRL-3 miRNA was employed to knockdown PRL-3 expression in human SGC7901 gastric cancer cells. MTT assay and tumor implantation experiment were conducted to determine the role of PRL-3 in the proliferation of SGC7901 cells and the tumor growth.

RESULTSTransfection of recombinant lentivirus expressing artificial PRL-3 miRNA significantly suppressed the proliferation of SGC7901 cells in vitro. The implanted tumor size of the PRL-3 transfection group was (1.92 +/- 0.18) cm3, significantly smaller than those in control groups [(4.74 +/- 0.39) cm3] (P < 0.05).

CONCLUSIONSSilencing of PRL-3 significantly suppressed the proliferation of SGC7901 cells and tumor growth in vivo. PRL-3 could be a potential therapeutic target in gastric cancer.

OBJECTIVETo evaluate the diagnostic value of 3.0 T diffusion-weighted imaging with background suppression (DWIBS) magnetic resonance (MR) for lymph node metastasis in rectal cancer.

METHODSThirty-five patients with rectal cancer who underwent preoperative routine MRI+DWI examination were enrolled in the study and were treated by rectal cancer resection plus lymph node dissection. Metastatic and non-metastatic lymph nodes were confirmed by postoperative pathology. Apparent diffusion coefficient (ADC) values, long-axis and short-axis diameters of lymph nodes were measured. Receiver operating characteristic (ROC) curve was used to assess the diagnostic efficacy of ADC, long-axis and short-axis diameters for differentiating metastatic lymph nodes from non-metastatic lymph nodes.

RESULTSA total of 151 lymph nodes were confirmed with exact location in 35 patients. Sixty-five metastatic lymph nodes and 86 non-metastatic lymph nodes were identified. The ADC values of metastatic lymph nodes and non-metastatic lymph nodes were(0.86±0.14)×10(-3) and (0.94±0.16)×10(-3) mm(2)/s respectively. The long-axis diameter were(9.78±3.13) and (7.90±1.77) mm, respectively. The short-axis diameter were (7.65±2.00) and (6.45±1.19) mm, respectively. There were statistically significant differences between metastatic and non-metastatic lymph nodes in ADC values, long-axis diameter, and short-axis diameter(all P<0.01). The areas under the ROC curve of ADC value, long-axis diameter, and short-axis diameter were 0.648, 0.706, and 0.692, respectively. Optimal cutoff values for these parameters were 1.05×10(-3) mm(2)/s, 7.95 mm, and 5.90 mm, respectively, and the corresponding sensitivities and specificities were 93.8% and 30.2%, 75.4% and 61.6%, 90.8% and 38.4%.

CONCLUSIONSQuantitative measurement of ADC value may reflect the degree of diffusion restriction of metastatic lymph nodes by DWIBS at 3.0 T MR. Accurate diagnosis of metastatic lymph nodes in rectal cancer demands comprehensive evaluation combining ADC value with diameter measurement.

OBJECTIVE: To analyze the clinical phenotype and pathogenic variant in a child diagnosed with mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH). METHODS: Clinical phenotype of the child was reviewed. Whole exome sequencing was carried out for the child. Candidate variant was verified by Sanger sequencing of the family member. RESULTS: The proband manifested dyskinesia, development delay, cerebellar hypoplasia and bilateral hearing impairment. WES results revealed that the proband has carried a pathogenic c.1641_1644delACAA (p.Thr548Trpfs*69) variant of the CASK gene, which was verified by Sanger sequencing to be a de novo variant. CONCLUSION The c.1641_1644delACAA (p.Thr548Trpfs*69) variant of the CASK gene probably underlay the MICPCH in the proband. Above finding has provided a basis for genetic counseling. WES should be considered for the diagnosis of neurological dysplasia.

OBJECTIVE: To analyze the clinical features and pathogenesis of a fetus with holoprosencephaly. METHODS: The findings of prenatal ultrasonography was reviewed. Following elective abortion, whole exome sequencing (WES) was carried out to identify potential pathogenic variant. Copy number variants (CNVs) of the abortus and its parents were detected by low-depth high-throughput sequencing. The parents were also analyzed by chromosomal karyotyping. RESULTS: Prenatal ultrasound suggested that the fetus had holoprosencephaly. WES revealed that it had approximately 33 Mb deletion at chromosome 13 involving ZIC2, a haploid dose sensitive gene. The results of low-depth high-throughput sequencing confirmed that the fetus carried a de novo 32.32 Mb deletion at 13q31.1-34. Karyotyping analysis has excluded gross chromosomal aberration in both parents. CONCLUSION The fetus was diagnosed with holoprosencephaly, which may be attributable to the 13q31.1-34 deletion involving the ZIC2 gene.
