To analyze the disease burden and trends of motor neuron disease(MND) in China and globally from 1990 to 2021, providing evidence for the formulation of relevant health strategies inChina.

PURPOSE: Rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone administered every 3 weeks (R-CHOP-21) is the standard care for diffuse large B-cell lymphoma (DLBCL). It is unknown whether the dose-dense R-CHOP (R-CHOP-14) could improve the outcome of the disease in Asian population. MATERIALS AND METHODS: Newly diagnosed DLBCL patients were centrally, randomly assigned (1:1) to receive R-CHOP-14 or R-CHOP-21. R-CHOP-14 was administered every 2 weeks, and R-CHOP-21 was administered every 3 weeks. Primary end point was disease-free survival (DFS). Secondary end points included overall survival (OS), progression-free survival (PFS), response rate and toxicities. RESULTS: Seven hundred and two patients were randomly assigned to receive R-CHOP-14 (n=349) or R-CHOP-21 (n=353). With a median follow-up of 45.6 months, the two groups did not differ significantly in 3-year DFS (79.6% for R-CHOP-14 vs. 83.2% for R-CHOP-21, p=0.311), 3-year OS (77.5% for R-CHOP-14 vs. 77.6% for R-CHOP-21, p=0.903), or 3-year PFS (63.2% for R-CHOP-14 vs. 66.1% for R-CHOP-21, p=0.447). Patients with an International Prognostic Index (IPI) score ≥ 2 had a poorer prognosis compared to those with an IPI score < 2. Grade 3/4 hematologic and non-hematologic toxicities were manageable and similar between R-CHOP-14 and R-CHOP-21. CONCLUSION: R-CHOP-14 did not improve the outcome of DLBCL compared to R-CHOP-21 in Asian population. With manageable and similar toxicities, both of the two regimens were suitable for Asian DLBCL patients. For high-risk patients with IPI ≥ 2, new combination regimens based on R-CHOP deserve further investigation to improve efficacy.

Objective To compare the clinical efficacy of gemcitabine arterial infusion chemotherapy with intravenous chemotherapy in the management of patients with advanced pancreatic cancer and to evaluate the efficacy and safety of gemcitabine arterial infusion chemotherapy. Methods 43 patients with advanced pancreatic cancer were included in this study, of whom 21 patients received arterial infusion chemotherapy (Group A) and the other 22 were treated by intravenous chemotherapy (Group B), gemcitabine combined with 5-FU chemotherapy was administrated in both groups. The main outcomes were clinical benefit response (CBR), tumor response rate and toxicity. Results Compared with Group B, there was a significant improvement of CBR in group A (81% vs 50%, P =0.033) ; there was also significant improvement of pain control in group A (76.2% vs 45.5%, P =0.039). There was no significant difference in the tumor response rate between two groups (33.3% vs 22.7%, P =0.498). No significant increase of side effects was observed in both groups. Conclusions In the management of advanced pancreatic cancer, the arterial infusion method may be more favorable than intravenous approach in improving clinical benefits with mild toxicity and well tolerability.

Objective: To analyze the association between hepatitis B virus (HBV) infection and pancreatic cancer. Methods: Retrospective analysis was performed to explore the positive rate of serum hepatitis B virus surface antigen (HBsAg) in patients with pancreatic cancer, lung cancer, diabetes mellitus and general population. Z test was used to compare the rate of HBV infection between the samples and general population. The rates among the samples were compared by Chi-square test. Results: A total of 3,701 registered patients seen in our hospital between January 1st 2003 and March 31st 2009 were collected. There were 230 pancreatic cancer patients with a positive rate of serum HBsAg of 16.1%, 1,188 lung cancer patients with a positive rate of serum HBsAg of 10.7%, and 2,283 patients with diabetes mellitus with a positive rate of serum HBsAg of 11.6%. There was no statistical significance in Z-test results between lung cancer patients and general population (Z=1.104, P=0.163), but the Z-test results between patients with diabetes mellitus and general population showed a statistical significance (Z=2.98, P=0.002). The positive rate of HBsAg was higher in pancreatic cancer patients than that in lung cancer patients (OR=1.60, 95% Cl: 1.077-2.382, r=5.487, P=0.019). Similar results were found between pancreatic cancer patients and diabetic patients (OR=1.46, 95% CI: 1.004-2.123, r=3.965, P=0.046). Conclusion: The positive rate of HBsAg is high in pancreatic cancer patients. There might be an association between HBV infection and pancreatic cancer.

Objective To discuss the influence of distribution of nursing human resource in maternalinfant wards on patients'satisfaction degree.Methods To analyze the satisfaction degree with nursing quality of all patients and distribution of nursing human resource in maternal-infant wards in our hospital in 2007.Results There was a positive correlation between inpatients'satisfaction of nursing service and distribution of nurses.Theinsufficiency of distribution of nursing human resource in maternal-infant wards caused nurses' sensation of work tiredness,degradation of service quality,bad service attitude,indifference to patients,lack of detail service,insufficiency of basic nursing care,simplistic health education,and unwarranted quality of technique operation.Conclusions The distribution of nursing human resource in maternal-infant wards should be hisher than that in common wards and We should pay attention to the distribution of naming safety in maternal-in-fant wards,increase nurse staffing,rationally utilize human resource,enhance training of comprehensive quality of nurses,strengthen quality awareness,service awareness and safety awareness,ensure the nursing quality and mother-infant safety,and improve patients'satisfaction.

[Objective] To investigate the efficacy of Xiangsha Yangwei Wan (XYW) on the inhibition of chemotherapy-induced chemical gastritis and upper gastrointestinal symptoms. [Methods] A randomized controlled trial (RCT) was carried out in 87 cases of maligant tumor confirmed by histopathological and cytological examination. All the cases were treated with chemotherapy regimen of adriamycin ( ADM) , adcarbazine ( DTIC) , platinum-based agents, irinotecan (CPT-11) and fluorouraeil (5-FU). Meanwhile, 41 cases in group A were also treated with dexamethason and 5-HT3 receptor antagonist as an essential anti-emesis and with XYW to regulate gastrointestinal function; other 46 cases in group B were given dexamethason and 5-HT3 receptor antagonist only. Seven days after treatment, incidences of chemical gastritis and upper gastrointestinal symptoms were observed and compared between the two groups. [Results] Seven days after chemotherapy, upper gastrointestinal symptoms and signs were relieved in 95.1% (39/41) of the patients of group A and in 76.1 % (35/46) of group B; the occurring rate of chemical gastritis with symptoms was 2.4% (1/41) in group A and 19.6% (9/46) in group B, the differences being significant statistically between the two groups( P - 0.0122) . [ Conclusion ] XYW has an inhibitory effect on chemotherapy-induced chemical gastritis and upper gastrointestinal symptoms.
