OBJECTIVE: The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks. METHODS: A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). RESULTS: During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43). CONCLUSION Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

Objective:To investigate the clinical effect of extraperitoneal robot-assisted laparoscopic modified Y-V plasty(LMYVP)in the treatment of refractory bladder neck contracture(BNC).Methods:We retrospectively analyzed the clinical data on 10 cases of refractory BNC after transurethral resection of the prostate between September 2020 and January 2023,all with a history of recurrent urethral dilatation and at least two failures in transurethral surgical treatment of scarring.After definite diagnosis and re-moval of some of the scar tissues to flatten the elevated bladder neck under the cystoscope,we performed robot-assisted LMYVP using the da Vinci Si robotic system and a four-port extraperitoneal approach.The surgical procedure involved an inverted T-shaped incision in the bladder neck and urethral stricture ring,an inverted V-shaped excision of the scar area at the 3-9 o'clock position on the ventral side of the prostatic urethra,continuous full-layer suturing of the bladder neck and inverted V-shaped urethra with 3-0 barbed thread,and indwelling of an F20 silicone catheter for 2 weeks.At 3 months after surgery,we performed cystoscopic examination,measured the maximum urinary flow rate(Qmax),and obtained the IPSS and quality of life(QOL)scores of the patients.Results:Operations were successfully completed in all the cases.At 3 months after surgery,the patients showed significantly increased Qmax([3.65±1.27]vs[20.3±1.77]ml/s,P＜0.05),IPSS(5.9±2.02 vs 30±1.15,P＜0.05)and QOL score(1.3±0.95 vs 5.2±0.79,P＜0.05)compared with the baseline.Cystoscopy revealed a wide and flat bladder neck with good survival and hemody-namics of the bladder flap.All the patients met the criteria for clinical cure at a median follow-up of 13.2 months.Conclusion:Extraper-itoneal robot-assisted LMYVP provides a new strategy for urinary tract reconstruction in the management of refractory BNC,with the ad-vantages of minimal invasiveness,high efficiency and high success rate.

OBJECTIVE: This study aimed to investigate the association between fruit and vegetable intake and arterial stiffness. METHODS: We conducted a cohort-based study comprising 6,628 participants with arterial stiffness information in the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) project. A semi-quantitative food-frequency questionnaire was used to assess baseline (2007-2008) and recent (2018-2021) fruit and vegetable intake. We assessed changes in fruit and vegetable intake from 2007-2008 to 2018-2021 in 6,481 participants. Arterial stiffness was measured using the arterial velocity-pulse index (AVI) and arterial pressure-volume index (API). Elevated AVI and API values were defined according to diverse age reference ranges. RESULTS: Multivariable-adjusted linear regression models revealed that every 100 g/d increment in fruit and vegetable intake was associated with a 0.11 decrease in AVI ( B= -0.11; 95% confidence interval [ CI]: -0.20, -0.02) on average, rather than API ( B = 0.02; 95% CI: -0.09, 0.13). The risk of elevated AVI (odds ratio [ OR] = 0.82; 95% CI: 0.70, 0.97) is 18% lower in individuals with high intake (≥ 500 g/d) than in those with low intake (< 500 g/d). Furthermore, maintaining a high intake in the past median of 11.5 years of follow-up was associated with an even lower risk of elevated AVI compared with a low intake at both baseline and follow-up ( OR = 0.64; 95% CI: 0.49, 0.83). CONCLUSION Fruit and vegetable intake was negatively associated with arterial stiffness, emphasizing recommendations for adherence to fruit and vegetable intake for the prevention of arterial stiffness.

BACKGROUND: The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease (CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project (Prediction for Atherosclerotic Cardiovascular Disease Risk in China). METHODS: A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors (LFs) (smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The risk advancement periods (RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage (PAR%) were also calculated. RESULTS: A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1 healthy LFs, maintaining 3-4 healthy LFs was associated with a 40% risk reduction of incident CVD (HR = 0.60, 95% CI: 0.45-0.79) and delayed CVD risk by 6.31 years (RAP: -6.31 [-9.92, -2.70] years). The PAR% of maintaining 3-4 unhealthy LFs was 22.0% compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2 to 3-4 was associated with a 23% lower risk of CVD (HR = 0.77, 95% CI: 0.60-0.98). CONCLUSIONS Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

OBJECTIVE: To investigate the value of red blood cell distribution width (RDW) and fibrinogen (Fib) level for the evaluation of therapeutic efficacy and prognosis in patients with diffuse large B-cell lymphoma (DLBCL). METHODS: The relationship between RDW/Fib at initial diagnosis and efficacy and the clinical outcome was retro-spectively analyzed based on the study of 105 patients with DLBCL. The patients were divided into two groups: low RDW group (≤15%) and high RDW group (>15%), low Fib group (Fib≤4 g/L) and high Fib group (Fib>4 g/L) according to the normal values of RDW and Fib. Therapeutic efficacy, overall survival (OS) time and progression free survival (PFS) time were compared between two groups. The correlation between each factors and efficacy, prognosis was analyzed by univariate and multivariate regression. RESULTS: The therapeutic efficacy (P<0.001), OS time(P=0.004), and PFS time(P=0.007) were poorer in the high RDW group as compared with the low RDW group. The efficacy (P=0.015) and PFS time(P=0.04) were poorer in the high Fib group as compared with the low Fib group. Multivariate analysis showed that high RDW was the independent risk factor for efficacy of DLBCL patients (OR=3.394, 95% CI 1.093-10.539, P=0.035). CONCLUSION High RDW and high Fib associate with poor efficacy in DLBCL patients.

BACKGROUND: The association of milk intake with cardiovascular disease (CVD) and cause-specific mortality remained controversial and evidence among the Chinese population was limited. We aimed to study the relationship between milk intake and CVDs among general Chinese adults. METHODS: A total of 104,957 participants received questionnaire survey. Results of physical examination such as anthropometric measurements and biochemical tests during 2007 to 2008, demographic data and their information on milk intake were collected through standardized questionnaires. Cox proportional hazard regression models were used to calculate hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs) of CVD incidence, cause-specific mortality and all-cause mortality related to milk intake. Restricted cubic splines (RCSs) were applied to examine dose-response associations. RESULTS: Among the 91,757 participants with a median follow-up period of 5.8 years, we documented 3877 CVD cases and 4091 all-cause deaths. Compared with participants who never consumed milk, the multivariate-adjusted HRs (95% CIs) of CVD incidence for 1 to 150 g/day, 151 to 299 g/day, and ≥300 g/day were 0.94 (0.86-1.03) (P > 0.05), 0.77 (0.66-0.89) (P < 0.05), and 0.59 (0.40-0.89) (P < 0.05), respectively; each 100 g increase of daily milk intake was associated with 11% lower risk of CVD incidence (HR, 0.89; 95% CI: 0.85-0.94; P < 0.001), and 11% lower risk of CVD mortality (HR, 0.89; 95% CI: 0.82-0.97; P = 0.008) after adjustment for age, sex, residential area, geographic region, education level, family history of CVD, smoking, alcohol drinking, physical activity level, body mass index, and healthy diet status (ideal or not). RCS analyses also showed a linear dose-response relationship with CVD (P for overall significance of the curve <0.001; P for non-linearity = 0.979; P for linearity <0.001) and stroke (P for overall significance of the curve = 0.010; P for non-linearity = 0.998; P for linearity = 0.002) incidence, and CVD mortality (P for overall significance of the curve = 0.045; P for non-linearity = 0.768; P for linearity = 0.014) within the current range of daily milk intake. CONCLUSIONS Daily milk intake was associated with lower risk of CVD incidence and mortality in a linear inverse relationship. The findings provide new evidence for dietary recommendations in CVD prevention among Chinese adults and people with similar dietary pattern in other countries.

INTRODUCTIONThe properties of a tumor itself were considered the main factors determining the survival of patients with locally recurrent nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT). However, recurrent tumors were mainly evaluated by using the American Joint Committee on Cancer staging system, which was modeled on primary tumors and did not incorporate the tumor volume. This study aimed to investigate the prognostic values of the primary tumor location and tumor volume, and to determine whether evaluating these parameters could improve the current staging system.

METHODSMagnetic resonance (MR) images for 229 patients with locally recurrent NPC who underwent IMRT were analyzed retrospectively.

RESULTSThe skull base, parapharyngeal space, and intracranial cavity were the most common sites of tumors. There was a difference in the survival between patients with T1 and T2 diseases (77.6% vs. 50.0%, P<0.01) and those with T3 and T4 diseases (33.0% vs. 18.0%, P=0.04) but no difference between patients with T2 and T3 diseases (50.0% vs. 33.0%, P=0.18). Patients with a tumor volume≤38 cm3 had a significantly higher survival rate compared with those with a tumor volume>38 cm3 (48.7% vs. 15.2%, P<0.01).

CONCLUSIONSA new staging system has been proposed, with T3 tumors being down-staged to T2 and with the tumor volume being incorporated into the staging, which may lead to an improved evaluation of these tumors. This new system can be used to guide the treatment strategy for different risk groups of recurrent NPC.

This study aimed to investigate the prognostic values of the primary tumor location and tumor volume, and to determine whether evaluating these parameters could improve the current staging system. Methods:Magnetic resonance (MR) images for 229 patients with local y recurrent NPC who underwent IMRT were analyzed retrospectively. Results:The skul base, parapharyngeal space, and intracranial cavity were the most common sites of tumors.

BACKGROUND AND OBJECTIVEThe primary submucous type of nasopharyngeal carcinoma (NPC) or the recurrent NPC in the parapharyngeal space is difficult to be diagnosed histologically by conventional biopsy because of the obstruction of the surrounding structures. This study was performed to evaluate the needle biopsy approach through the madibular area into the parapharyngeal space under the guidance of computed tomography (CT) for NPC.

METHODSBetween July 6, 2005 and October 23, 2009, a total of 6 patients were enrolled into the study. Two patients with cervical lymph node metastasis were clinically suspicious of NPC according to their clinical manifestations. However, no cancer cell could be found by repeated nasopharyngeal biopsies followed by histologic examinations. The other 4 patients were diagnosed with recurrent NPCs by magnetic resonance imaging (MRI) or/and positron emission tomography (PET)-CT scan, showing tumors in the parapharyngeal spaces in 3 patients and enlarged retropharyngeal lymph node in 1 patient. The CT-guided puncture was performed through the mandibular skin and the cutting needle biopsy was taken at the parapharyngeal space focus.

RESULTSAll the cutting needle biopsies of projected locations have been performed safely. Finally, all the 7 specimens met the requirement of pathologic diagnosis and the cases were all confirmed histologically to be NPCs. The main complication was mild ache at the puncture point. No blood vessel or nerve was injured and no patient needed special treatment.

CONCLUSIONSThe CT-guided puncture biopsy of the parapharyngeal space through the mandibular area is simple and feasible. It can be an additional option for routine nasopharyngeal biopsy.
