Objective To explore the relationship of different body mass index, waist circumference and serum lipid levels with essential hypertension among residents of Ningbo. And to explore the predictive value of BMI and WC (Waist Cir-cumference) for hypertension. Methods Adopting cluster sampling, 2 303 people (1 081 cases of hypertension and 1 222 people with normal blood pressure) were collected in the four townships of Ningbo City. We conducted questionnaires, physi-cal examination and blood lipid testing for all of subjects. WC group:WC≥85 cm in male or WC≥80 cm in female is central obesity, and the others are normal. BMI groups:BMI≥24 kg/m2 is overweight, and BMI<24 kg/m2 is normal. The relationship of BMI, WC and serum lipid levels with hypertension was analyzed by multivariate unconditional logistic regression model. The predictive value of BMI and WC for hypertension was analyzed by receiver operating characteristic (ROC) curve. Results WC, BMI, total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in hypertension group were higher than those in control group (P<0.01). And WC, BMI, TG, LDL-C is the impact factor for hypertension. The overweight rate and central obesity rate in hypertension group were higher than control group (P<0.01). TG and LDL-C level abnormality, overweight and central obesity were the risk factors of hypertension. As a risk factor of hypertension, over-weight with central obesity group is higher than overweight with normal waistline group, simple central obesity group and nor-mal group. In the area under the ROC curve, BMI is higher than WC in both male and female population. Conclusion WC, BMI, TG and LDL-C abnormalities were risk factors for hypertension, and BMI was a better predictive factor for hyper-tension than WC.

Building an integrated health care service system is key to the Healthy China strategy. Based on the integrated health care service conceptual framework, the authors took two pilots regions of health-centered medical alliances in Zhejiang province as an example, and analyzed their conception framework, organizational structure, operation elements and effects. The study found initial success of the two alliances in terms of the contents, capabilities, effects and satisfaction of primary health care service. Such alliances feature a health-centered multi-entity participation mechanism, carry out health care and prevention integration leveraging the information platform, hence conducive to the effective governance of the alliances. However, the contents of their health related services are expected to be broadened and deepened; functionalities of health-related institutions need to be clarified and refined, while their performance appraisal needs to be further improved.

Objective:To study the minimally invasive fixation with virtual self-designed screws between the iliac plates for acetabular posterior column fractures and compare the differences between genders.Methods:The CT data were collected from the 80 patients with normal pelvis who had undergone pelvic CT scan due to physical examination or trauma at Department of Orthopaedics, The Third Hospital of Xiamen from June 2021 to June 2022. There were 40 males and 40 females with an age of (45.0±12.4) years. The virtual screws between the minimally invasive iliac plates were designed with design software after 3D modeling. The insertion point, screw length, screw diameter, angle between the screw and the coronal plane of the pelvis, angle between the screw and the sagittal plane of the pelvis, angle ε between the screw and the anterior edge bone crest line of the greater sciatic notch, and bone channel volume were measured. Comparisons of the above data were made between genders. Results:The insertion point of the screw between the minimally invasive iliac plates was located between the anterior superior iliac spine and the iliac tubercle nodule, going toward the area between the ischial spine and the small ischial notch. The screw length was (139.64±8.46) mm, the screw diameter (8.95±1.16) mm, and the bone channel volume (51.91±10.77) cm 3. The screw length [144.34±7.58) mm], screw diameter [9.50±0.98) mm], angle between the screw and the sagittal plane of the pelvis (31.14°±2.74°), and bone channel volume [(57.82±8.82) cm 3] for males were significantly larger than those for females [(134.95±6.48) mm, (8.40±1.07) mm, 26.72°±2.74°, and (46.01±9.22) cm 3], while the angle between the screw and the sagittal plane of the pelvis [(35.74°±3.85°) mm] and angle ε between the screw and the anterior edge bone crest line of the greater sciatic notch (11.96°±4.57°) for males were significantly smaller than those for females (36.89°±2.96° and 14.17°±5.15°) (all P < 0.05). Conclusions:Fixation with screws between the iliac plates provides a new treatment for acetabular posterior column fractures, because the screws can be placed percutaneously in a minimally invasive manner or antegradely. The screw length, screw diameter, angle between the screw and the sagittal plane of the pelvis, and bone channel volume for males are significantly larger than those for females, while the angle between the screw and the sagittal plane of the pelvis and the angle between the screw and the anterior edge bone crest line of the greater sciatic notch for males are significantly smaller than those for females. Therefore, the angles between the iliac plate screw and the sagittal and coronal planes of the pelvis should be adjusted according to gender in screw placement.

Objective:To explore the CT three-dimensional reconstruction in percutaneous balloon compression of the semilunar ganglion of trigeminal nerves.Methods:Thirty-one patients with trigeminal neuralgia, admitted to our hospital from May 2018 to August 2018, were treated by percutaneous balloon compression of the semilunar ganglion of trigeminal nerves. All patients underwent intraoperative mobile CT scan; the distance from the external aperture of foramen ovale to the petrous ridge, the angle from puncture needle and the petrous ridge, and the angle from puncture needle and the clivus were analyzed by three-dimensional reconstruction technology. Prognoses were recorded immediately after surgery and 10-12 months after follow-up.Results:The distance from the external aperture of foramen ovale to the petrous ridgea was (2.14±0.17) cm, ranged from 1.83 cm to 2.42 cm. The angle from puncture needle and the petrous ridge was (102.03±7.60)°, ranged from 91.00° to 116.00°. The angle from puncture needle to the clivus was (68.03±7.06)°, ranged from 52.00° to 80.00°. The puncture succeeded in all patients under the help of CT three-dimensional reconstruction. The volume of the inflated balloon ranged from 0.30 cm 3 to 0.47 cm 3 (averaged 0.42±0.05 cm 3). The compression time ranged from 3.00 min to 5.00 min (averaged 4.72±0.53 min). The incidence of diplopia was 3.23%, and the incidence of dry eyes/decreased corneal sensation was 12.90%. During the follow-up, one patient relapsed 10 months after surgery; the left patients recovered with disappeared complications. Conclusion:The CT 3D reconstruction can reduce the difficulty of ovale foramen puncture during operation, assist the judgment and adjustment of intraoperative balloon volume, and improve the surgical efficacy.

ObjectiveTo evaluate the overall dietary intake of adult residents in Sijing Town, Songjiang District, Shanghai, and to explore the association between dietary health literacy and diet quality. MethodsA total of 1 280 adult residents were selected as the research subjects using a multi-stage sampling method, and face-to-face questionnaire surveys were administered on site. Dietary intake data were collected using a Food Frequency Questionnaire (FFQ), and the overall diet quality of the participants was evaluated based on the Chinese Healthy Eating Index (CHEI). Participants were divided into low- and high-CHEI groups according to the median CHEI score. Logistic regression models were used to examine the association between dietary health literacy and diet quality. ResultsThe median CHEI score for adults in the area was 63.68 points. Multivariate logistic regression analysis revealed that adults with lower dietary health literacy had lower CHEI scores and poorer overall diet quality compared to those with higher dietary health literacy (OR=1.435, 95%CI:1.132‒1.819). ConclusionThe overall diet quality of adult residents in this region requires improvement. There is a significant positive correlation between the level of dietary health literacy and CHEI scores, suggesting that enhancing dietary health literacy may be an important strategy to improve resident’ dietary quality.

BACKGROUND: Both aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism and lifestyle behaviors are involved in coronary artery disease (CAD), while the interaction between them is currently unknown. METHODS: A nested case-control study was conducted in 161 patients with CAD and 495 controls in dyslipidemia population in Yinzhou District, Ningbo, Zhejiang Province, China, in August 2013. Anthropometric data and blood samples were collected, demographic characteristics and lifestyle behaviors information were obtained by a face-to-face interview, dietary intake was assessed by a food frequency questionnaire, and genomic DNA was genotyped. RESULTS: Carriers with increasing number of A alleles had an elevated CAD risk compared with G allele carriers (adjusted OR = 1.483, 95% CI = 1.114-1.974). Carriers of rs671 A/G and A/A genotypes had a higher CAD risk than carriers of G/G genotype (adjusted OR = 1.492, 95% CI = 1.036-2.148). Similarly, individuals with rs671 A/A genotype had a higher CAD risk than individuals with A/G and G/G genotypes (adjusted OR = 2.161, 95% CI = 1.139-4.101). We found a borderline additive interaction between regular fried food intake and A/A and A/G genotypes, and a significantly additive interaction between sedentary/light physical activity and A/A and A/G genotypes. CONCLUSIONS Individuals with A/A or A/G genotypes of rs671 have a higher CAD risk, if they lack physical activity and take fried food regularly, than individuals with G/G genotypes. These findings can help to provide a guide to targeted heart health management.
