Onset of Coronary Heart Disease is Associated with HCMV Infection and Increased CD14 CD16 Monocytes in a Population of Weifang, China / 生物医学与环境科学（英文）

Objective@#To investigate the relationship between human cytomegalovirus (HCMV) infection and peripheral blood CD14 CD16 monocytes in the pathogenesis of coronary heart disease (CHD), and to elucidate the mechanism of pathogenesis in CHD by analyzing the correlation between infection, inflammation, and CHD, to provide a basis for the prevention, evaluation, and treatment of the disease.@*Methods@#In total, 192 patients with CHD were divided into three groups: latent CHD, angina pectoris, and myocardial infarction. HCMV-IgM and -IgG antibodies were assessed using ELISA; CD14 CD16 monocytes were counted using a five-type automated hematology analyzer; mononuclear cells were assessed using fluorescence-activated cell sorting; and an automatic biochemical analyzer was used to measure the levels of triglyceride, cholesterol, high- and low-density lipoprotein cholesterols, lipoprotein, hs-CRp and Hcy.@*Results@#The positive rates of HCMV-IgM and -IgG were significantly higher in the CHD groups than in the control group. HCMV infection affects lipid metabolism to promote immune and inflammatory responses.@*Conclusion@#HCMV infection has a specific correlation with the occurrence and development of CHD. The expression of CD14 CD16 mononuclear cells in the CHD group was increased accordingly and correlated with acute HCMV infection. Thus, HCMV antibody as well as peripheral blood CD14 CD16 mononuclear cells can be used to monitor the occurrence and development of CHD.

Treatment of spine metastases by open decompression, microwave ablation combined with open vertebroplasty and pedicle screw rod system / 中国骨伤

OBJECTIVE@#To evaluate the preliminary clinical effective of open decompression, microwave ablation combined with open vertebroplasty and pedicle screw rod system in the treatment of spine metastases.@*METHODS@#The clinical data of 12 patients with spine metastases were retrospectively analyzed, they were treated with open decompression, microwave ablation combined with open vertebroplasty and pedicle screw rod system between January 2014 and January 2016. Six males and 6 females were included, aged from 30 to 75 years old with an average of 55.6 years. There were 5 cases with spine metastases from lung cancer, 2 from breast cancer, 2 from thyroid cancer, 2 from renal cancer and 1 from liver cancer. Sevencases were thoracic metastases and 5 cases were lumbar metastases. Tomita score were mainly arranging from 3 to 6 points. According to ASIA neurologic grading system, 3 patients were grade C, 1 was grade D, 8 were grade E. Preoperative VAS score was 8.3±0.4. VAS was used to evaluate the clinical effect at 1, 3, 6 months after operation and final follow-up.@*RESULTS@#All operations were successful and the amount of blood loss during surgery was 500 to 2 050 ml (average of 850 ml), operation time was 3.5 to 5.5 h (average of 4.5 h). There was no nerve root injury during surgery. Cerebrospinal fluid leakage occurred in 3 cases after surgery, which were healed after conservative treatment. Superficial infection of the incision occurred in 2 cases, which were healed after dressing change. There was one case of pulmonary infection. No deep infection, lower limb thrombosis or other complications were found. All 12 patients were followed up for 9 -40 months with an average of 28.6 months. The clinical symptoms of all patients were significantly improved, and the motor function of the lower limbs was recovered to varying degrees. According to ASIA grade, 2 cases of grade C were improved to grade B;1 case of grade C did not recover significantly;1 case of grade D was improved to grade E. One patient died of primary liver cancer 10 months after surgery. Local tumor recurrence occurred in 1 patient during follow up period. The VAS scores were 2.7±0.6, 2.5±0.4, 2.6±0.5, and 2.5±0.5 at 1, 3, 6 months after surgery and at final follow-up, which were significantly improved compared with the score before surgery(<0.05).@*CONCLUSION@#Open decompression, microwave ablation combined with open vertebroplasty and pedicle screw rod system in the treatment of spine metastases show some effects, with less intraoperative blood loss, shorter operation time, significant postoperative pain relief, and low tumor recurrence rate.

Progress in the encoding characteristics and mechanisms of hippocampal neural assemble sequences in spatial memory / 生理学报

The formation, consolidation and retrieval of spatial memory depend on sequential firing patterns of place cells assembling in the hippocampus. Theta sequences of place cells during behavior play a role in acquisition of spatial memory, trajectory prediction and decision making. In awake rest and slow wave sleep, place cell sequences occur during the sharp wave-ripples (SWRs), called "replay", which is crucial for memory consolidation and retrieval. In this review, we summarize the functional significances of theta sequences and SWRs replay sequences and the mechanism of these sequences. We also discuss the relationship between theta and replay sequences with the formation of spatial memory. We propose the research direction in this field in future and aim to provide new ideas for related researches.

Diatoms Distribution in Ningbo Three-river Watershed during Summer / 法医学杂志

OBJECTIVES@#To explore the species, quantity and distribution of diatoms in Ningbo three-river watershed during summer and to provide scientific basis for forensic examination of drowning cases in the waters of Ningbo.@*METHODS@#Water samples were collected in July and August of 2015. Fourteen water sampling points were selected from the Yao River, the Fenghua River and the Yong River. The morphological features of diatom species and dominant diatoms were distinguished by microscope.@*RESULTS@#A total of 16 species of diatoms were detected in the Yao River, the Fenghua River and the Yong River. Melosira was the dominant species in the Yao River, and the quantity and richness were higher than in other rivers. The richness of Cyclotella in the Yong River was higher than in other rivers. The richness of Pinnularia and Licmophora were higher in the Fenghua River than in the Yao River and the Yong River.@*CONCLUSIONS@#The species and proportion of diatom is different in each river. Database of the species and relative composition for the diatoms in corresponding river is established, which may provide data support for forensic examination of drowning cases in Ningbo three-river watershed.
