Objective： The current study was designed to investigate the diagnosis and the treatment of osteoradionecrosis of the skull base (ORN) in the patients with nasopharyngeal carcinoma (NPC) after radiotherapy. Methods： All patients (n=12) diagnosed as nasopharyneal carcinoma and osteoradionecrosis of the skull base were studied retrospectively with their clinical manifestations, diagnoses, therapies and prognoses. Results： ORN was found with characteristic CT and endoscopic findings, they were never seen in the patients with NPC relapse. The latent periods of ORN in the patients after primary radiotherapy were 3 - 15 years, while the periods were 7 months - 2 years in the patients after reirradiation. Six patients with local ORN were operated, 1 patients was died of exhaustion; Six patients with extensive ORN were treated using conservative methods, 3 patients were died of severe nasopharyngeal bleeding, while one were died of exhaustion. Conclusion： The ORN of the skull base after radiotherapy could be diagnosed by CT and endoscopic findings. The patients with extensive ORN or radiation induced cranial neuropathy were associated with poor prognosis. The most common causes of death were severe nasopharyngeal bleeding and exhaustion.

Objective To evaluate the association between resting heart rate (HR) and all-cause death and coronary heart disease (CHD) events in the Chinese cohort. Methods Data were obtained from the PRC-USA Cooperative Study on Cardiovascular and Cardiopulmonary Epidemiology. Baseline screen surveys were conducted in 1983 and 1984 from people aged 35 to 59 years living in urban or rural areas of Beijing and Guangzhou. Follow-up visits were performed for end point events of all-cause death and first CHD events every two years till 2005. Resting HR was determined from 5 consecutive intervals between R waves on the 12-lead electrocardiogram. Results A total of 9856 (4805 males) people were included in the study and the mean follow up duration was 16. 2 years. There were 1523 deaths, including 200 CHD events during the follow up period. Mean resting HR was 67. 9 beat per minute (bpm) in men and 71. 6 bpm in women respectively which had a trend to increase with aging. Cox Proportional Hazards model indicated the relative risk of all-cause death increased constantly with the increase of HR percentile after control of age, fasting glucose, serum cholesterol, serum triglyceride, body mass index, systolic blood pressure and diastolic blood pressure. With HR 60-89 bpm as control group, the relative risk and 95% confidence interval in group HR <50 bpm,50-59 bpm,90-99 bpm and ≥100 bpm were 0. 76(0. 49-1. 17) ,0. 87 (0. 75-1. 02) , 1. 33 ( 1. 06-1. 68) ,1.48 ( 1. 03-2. 14) respectively. However there was no significant correlation between HR and CHD events in studied population. Conclusion The risk of total death increased significantly in people with HR≥90 bpm suggesting higher resting heart rate might be an independent risk factor for all-cause death in the Chinese population.

BACKGROUND:At present,most of the experiments on the treatment of skin wound by mesenchymal stem cells have been performed in rats,mice and rabbits,while the research on skin wound treatment by canine bone marrow mesenchymal stem calls is less reported.OBJECTIVE:To observe the effect of canine bone marrow mesenchymal stem calls on skin wound healing.METHODS:A 3 cmx3 cm wound was made on the both sides of the scapula and buttocks of the dog,with the right side as experimental group and the left side as control group.After the wound was made,allogeneic canine bone marrow mesenchymal stem calls suspension was injected subcutaneously around the wound in the experimental group on the 1st and 3rd days.The control group was injected subcutaneously around the wound with mesenchymal stem call culture medium on the 1st and 3rd days after the wound was made.Wound healing was observed dynamically in both groups.RESULTS AND CONCLUSION:In the 1st week,there were pale yellow inflammatory substances in the wound of two groups indicating obvious inflammations.Compared with the control group,the inflammatory substances were fewer and the growth rate of the granulation tissue was faster in the experimental group.From the 2nd week until the wound healing,epithelialization on the wound became obvious following the formation of the granulation tissue,which was mainly displayed by the formation of fresh epithelial tissues from the surrounding to the wound center.The epithelialization time of the experimental group was earlier than that of the control group,and the wound area of the experimental group was smaller than that of the control group.In the 3rd week,the wound in the experimental group healed completely,and became smoother than that in the control group.The wound area of the experimental group was slightly smaller than that of the control group on the 8th and 12th days after cell transplantation,and the healing speed of the experimental group was slightly faster than that of the control group,but there was no significant difference between the two groups.Our findings indicate that the transplantation of canine bone marrow mesenchymal stem cells has the possibility or trend to promote skin wound healing.

Background::The goal of the assisted reproductive treatment is to transfer one euploid blastocyst and to help infertile women giving birth one healthy neonate. Some algorithms have been used to assess the ploidy status of embryos derived from couples with normal chromosome, who subjected to preimplantation genetic testing for aneuploidy (PGT-A) treatment. However, it is currently unknown whether artificial intelligence model can be used to assess the euploidy status of blastocyst derived from populations with chromosomal rearrangement.Methods::From February 2020 to May 2021, we collected the whole raw time-lapse videos at multiple focal planes from in vitro cultured embryos, the clinical information of couples, and the comprehensive chromosome screening results of those blastocysts that had received PGT treatment. Initially, we developed a novel deep learning model called the Attentive Multi-Focus Selection Network (AMSNet) to analyze time-lapse videos in real time and predict blastocyst formation. Building upon AMSNet, we integrated additional clinically predictive variables and created a second deep learning model, the Attentive Multi-Focus Video and Clinical Information Fusion Network (AMCFNet), to assess the euploidy status of embryos. The efficacy of the AMCFNet was further tested in embryos with parental chromosomal rearrangements. The receiver operating characteristic curve (ROC) was used to evaluate the superiority of the model. Results::A total of 4112 embryos with complete time-lapse videos were enrolled for the blastocyst formation prediction task, and 1422 qualified blastocysts received PGT-A ( n = 589) or PGT for chromosomal structural rearrangement (PGT-SR, n = 833) were enrolled for the euploidy assessment task in this study. The AMSNet model using seven focal raw time-lapse videos has the best real-time accuracy. The real-time accuracy for AMSNet to predict blastocyst formation reached above 70% on the day 2 of embryo culture, and then increased to 80% on the day 4 of embryo culture. Combing with 4 clinical features of couples, the AUC of AMCFNet with 7 focal points increased to 0.729 in blastocysts derived from couples with chromosomal rearrangement. Conclusion::Integrating seven focal raw time-lapse images of embryos and parental clinical information, AMCFNet model have the capability of assessing euploidy status in blastocysts derived from couples with chromosomal rearrangement.

OBJECTIVETo describe geographical distribution and its transition of mortality of cancers in China.

METHODSThe information of 2 513 949 310 person years were collected in 1973-1975 and 142 660 482 person years in 2004-2005 respectively. Being standardizing the death rates of these two survey with 2000 national census population, the changes of mortality of main cancers was observed and the geographic distribution of cancers in 2004-2005 was analyzed.

RESULTSA total of 1 865 445 cancer deaths were collected in 1973-1975, the standardized death rate was 99.61/100 000, and 193 839 cancer deaths were collected in 2004-2005, the standardized death rate was 123.72/100 000, with growth of 24.20%. District mortality analysis showed that the provincial standardized cancer death rates varied greatly, with the highest in Heilongjiang (7443 cases, 183.34/100 000), and the lowest in Yunnan (2454 cases, 61.03/100 000). The highest standardized death rate of esophageal cancer, gastric cancer, liver cancer, colon cancer, lung cancer, nasopharyngeal cancer, leukemia, female breast cancer, cervical cancer was in Henan (3535 cases, 32.95/100 000), Gansu (1333 cases, 59.35/100 000), Heilongjiang (1640 cases, 38.63/100 000), Shanghai (390 cases, 11.58/100 000), Heilongjiang (2382 cases, 60.15/100 000), Hainan (36 cases, 7.04/100 000), Tianjin (161 cases, 5.45/100 000), Heilongjiang (179 cases, 8.09/100 000), Xinjiang (131 cases, 10.69/100 000) respectively; the lowest standardized cancer death rate of above-mentioned cancers was in Yunnan (63 cases, 1.59/100 000), Beijing (235 cases, 5.95/100 000), Tianjin (454 cases, 10.86/100 000), Tibet (3 cases, 0.82/100 000), Tibet (12 cases, 3.29/100 000), Qinghai (0 case, 0.00/100 000), Tibet (1 cases, 0.28/100 000), Tibet (6 cases, 2.88/100 000), Chongqing (27 cases, 1.02/100 000) respectively.

CONCLUSIONComparing the two surveys, the standardized mortality of cancers was increased. Most of cancers occurred obviously in cluster by geographical distribution.

BACKGROUNDAttention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders during childhood, characterized by the core symptoms of hyperactivity, impulsivity and inattention and puts great burden on children themselves, their families and the society. Osmotic release oral system methylphenidate (OROS-MPH) is a once-daily controlled-release formulation developed to overcome some of the limitations associated with immediate-release methylphenidate (IR-MPH). It has been marketed in China since 2005 but still lacks data from large-sample clinical trials on efficacy and safety profiles. The aim of this study was to evaluate the effectiveness and safety of OROS-MPH in children aged 6 to 16 years with ADHD under naturalistic clinical setting.

METHODSThis 6-week, multi-center, prospective, open-label study enrolled 1447 ADHD children to once-daily OROS-MPH (18 mg, 36 mg or 54 mg) treatment. The effectiveness measures were parent-rated Inattention and Overactivity With Aggression (IOWA) Conners I/O and O/D subscales, physician-rated CGI-I and parent-rated global efficacy assessment scale. Blood pressure, pulse rate measurement, adverse events (AEs) and concomitant medications and treatment review were conducted by the investigator and were served as safety measures.

RESULTSA total of 1447 children with ADHD (mean age (9.52 ± 2.36) years) were enrolled in this trial. Totally 96.8% children received an OROS-MPH modal dose of 18 mg, 3.1% with 36 mg and 0.1% with 54 mg at the endpoint of study. The parent IOWA Conners I/O score at the end of week 2 showed statistically significant (P < 0.001) improvement with OROS-MPH (mean: 6.95 ± 2.71) versus the score at baseline (10.45 ± 2.72). The change in the parent IOWA Conners O/D subscale, CGI-I and parent-rated global efficacy assessment scale also supported the superior efficacy for OROS-MPH treatment. Fewer than half of 1447 patients (511(35.3%)) reported AEs, and the majority of the events reported were mild (68.2%). No serious adverse events were reported during the study.

CONCLUSIONThis open-label, naturalistic study provides further evidence of effectiveness and safety of OROS-MPH in school-aged children under routine practice.

Objective:To investigate the prognosis after salvage radiotherapy with or without hormone therapy for prostate cancer.Methods:From May 2014 to December 2020, 248 patients undergoing salvage radiotherapy due to prostate-specific antigen (PSA)persistence or biochemical progression after radical prostatectomy at Sun Yat-sen University Cancer Center (n=157) and West China Hospital, Sichuan University (n=91) were analyzed. Median age was 66 (45-78) years old. Median PSA was 23.50 (0.18-845.00) ng/ml. The number of PSA persistence and biochemical progression were 143 (59%) and 105 (42%). The number of pT 2, pT 3a, pT 3b, pT 4, and unknown T stage was 99, 49, 78, 15 and 7 cases.The number of N 0, N 1 and unknown N stage was 153, 44 and 51 cases. 165 cases had positive surgical margin. Gleason score of 6, 7, 8, >8 score and unknown was in 12, 104, 34, 90 and 8 patients. Early and late salvage radiotherapy was performed in 117 and 131 patients, and 70 patients (28%) were CRPC. Hormone therapy was used combined with radiotherapy in 182 patients (73%). PSA decline after radiotherapy was compared with Chi-squre test. Kaplan-Meier method and log-rank test were used to compare progression free-survival (PFS)after radiotherapy. Univariate and multivariate analyses of PFS were performed using Cox proportional hazards model. Early salvage radiotherapy was defined as PSA≤0.5 ng/ml before radiotherapy, and late salvage radiotherapy was defined as PSA>0.5ng/ml. Results:PSA response (PSA decline ≥50%) rate was 94% (233/248), and 82% (203/248) patients had PSA decline ≥ 90%. Twelve (5%) patients had rising PSA after completing radiotherapy, but only 4 (2%) had real progression. The median PFS was 69 months (95% CI 68-70), and 3-year and 5-year PFS rate were 80% and 67%. PFS of PSA persistence and biochemical progression were similar ( HR =0.71, 95% CI 0.37-1.37, P=0.311). Compared with late salvage radiotherapy, early salvage radiotherapy had better PFS [69 (95% CI 68-70) vs. 59 (95% CI 44-74) months, P<0.001]. Compared with hormone sensitive, castration-resistant was associated with worse PFS (5-year PFS rate 74% vs. 51%, P<0.001). In multivariate analysis, Gleason score>8, castration-resistant and late salvage radiotherapy were unfavorable prognostic factors. Conclusions:In patients receiving salvage radiotherapy with or without hormone therapy for PSA persistence and biochemical progression after radical prostatectomy, high PSA level before radiotherapy and castration resistant is associated with poor prognosis.

PURPOSE: The measuring Epstein-Barr virus (EBV) DNA is an important predictor of nasopharyngeal carcinoma (NPC). This study evaluated the predictive value of pretreatment serum amyloid A (SAA) and C-reactive protein (CRP) comparing with EBV DNA in patients with NPC. MATERIALS AND METHODS: In an observational study of 419 non-metastatic NPC patients, we prospectively evaluated the prognostic effects of pretreatment SAA, CRP, and EBV DNA on survival. The primary end-point was progress-free survival (PFS). RESULTS: The median level of SAA and CRP was 4.28 mg/L and 1.88 mg/L, respectively. For the high-SAA group (> 4.28 mg/L) versus the low-SAA (≤ 4.28 mg/L) group and the high-CRP group (> 1.88 mg/L) versus the low-CRP (≤ 1.88 mg/L) group, the 5-year PFS was 64.5% versus 73.1% (p=0.013) and 65.2% versus 73.3% (p=0.064), respectively. EBV DNA detection showed a superior predictive result, the 5-year PFS in the EBV DNA ≥ 1,500 copies/mL group was obviously different than the EBV DNA < 1,500 copies/mL group (62.2% versus 77.8%, p < 0.001). Multifactorial Cox regression analysis confirmed that in the PFS, the independent prognostic factors were including EBV DNA (hazard ratio [HR], 1.788; p=0.009), tumour stage (HR, 1.903; p=0.021), and node stage (HR, 1.498; p=0.049), but the SAA and CRP were not included in the independent prognostic factors. CONCLUSION: The results of SAA and CRP had a certain relationship with the prognosis of NPC, and the prognosis of patients with high level of SAA and CRP were poor. However, the predictive ability of SAA and CRP was lower than that of EBV DNA.
