OBJECTIVE: To investigate the effect of body mass index (BMI) on the short-term effectiveness of high tibial osteotomy (HTO) in the treatment of varus knee arthritis. METHODS: The clinical data of 84 patients (84 knees) with varus knee arthritis treated with HTO between May 2016 and August 2020 were retrospectively analyzed. According to BMI, the patients were divided into normal group (32 patients in group A, BMI<25 kg/m ²), overweight group (27 patients in group B, BMI>30 kg/m ²), and obese group (25 patients in group C, BMI>30 kg/m ²). The BMI of groups A, B, and C were (23.35±0.89), (26.65±1.03), and (32.05±1.47) kg/m ², respectively. There was no significant difference ( P>0.05) in gender, age, surgical side, disease duration, and preoperative Hospital for Special Surgery (HSS) score, visual analogue scale (VAS) score, knee range of motion, and hip-knee-ankle angle (HKA) between groups. The operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation were recorded and compared between groups. The improvement of knee joint function and pain status were evaluated by knee joint HSS score, knee range of motion, and VAS score before and after operation, and measuring the HKA of patients on X-ray film. During the follow-up, the X-ray films of the knee joint were reexamined to observe the position of the internal fixator and the healing of osteotomy. RESULTS: All patients completed the operation successfully and were followed up 8-40 months (mean, 19.3 months). There was no significant difference in follow-up time, operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation between groups ( P>0.05). No operative complications such as severe vascular or nerve injury occurred. After operation, deep venous thrombosis of lower extremities occurred in 1 case in groups A and B respectively, and fat liquefaction of surgical incision occurred in 2 cases in group C. There was no significant difference in the incidence of perioperative complications between groups (3.1% vs. 3.7% vs. 8.0%) ( P=0.689). During the follow-up, there was no bone nonunion, plate fracture or loosening. At last follow-up, HSS score, VAS score, knee range of motion, and HKA significantly improved in the 3 groups when compared with those before operation ( P<0.05), but there was no significant difference in the differences of the above indexes between groups before and after operation ( P>0.05). CONCLUSION BMI does not affect the short-term effectiveness of HTO in the treatment of varus knee arthritis. HTO can be selected for overweight and obese patients after standard medical treatment is ineffective.

Background: Domestic yaks are the most important livestock species on the Qinghai-Tibetan Plateau. Adult female yaks normally breed in the warm season (July to September) and enter anestrous in the cold season (November to April). Nevertheless, it is unclear how ovarian activity is regulated at the molecular level. Objectives: The peculiarities of yak reproduction were assessed to explore the molecular mechanism of postpartum anestrus ovaries in yaks after pregnancy and parturition. Methods: Sixty female yaks with calves were observed under natural grazing in Haiyan County, Qinghai Province. Three yak ovaries in pregnancy and postpartum anestrus were collected. RNA sequencing and quantitative proteomics were employed to analyze the pregnancy and postpartum ovaries after hypothermia to identify the genes and proteins related to the postpartum ovarian cycle. Results: The results revealed 841 differentially expressed genes during the postpartum hypoestrus cycle; 347 were up-regulated and 494 genes were down-regulated. Fifty-seven differential proteins were screened: 38 were up-regulated and 19 were down-regulated. The differential genes and proteins were related to the yak reproduction process, rhythm process, progesterone-mediated oocyte maturation, PI3K/AKT signaling pathway, and MAPK signaling pathway categories. Conclusions Transcriptome and proteomic sequencing approaches were used to investigate postpartum anestrus and pregnancy ovaries in yaks. The results confirmed that BHLHE40, SF1IX1, FBPX1, HSPCA, LHCGR, BMP15, and ET-1R could affect postpartum hypoestrus and control the state of estrus.

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 investigate the effect and mechanism of atorvastatin (ATV) on the inflammatory response of human renal tubular epithelial cells (HK-2 cells) induced by calcium oxalate crystals. Methods: HK-2 cells were divided into control group (normal medium), ATV group (after 3 h pretreatment with 40 μmol/L ATV, replaced with normal medium), calcium oxalate crystal stimulation group (4 mmol/L calcium oxalate crystal) and ATV treatment group (after 3 h pretreatment with 40 μmol/L ATV, replaced with 4 mmol/L calcium oxalate crystals). After 12 h, the cells were collected, and the expression levels of NLRP3 and Cleaved caspase-1 were detected by immunohistochemical staining and Western blotting. The expression level of NF-κB was detected by immunofluorescence and Western blotting. The cell culture supernatant was collected to detecte the concentrations of interleukin-1β (IL-1β) and interleukin-18 (IL-18) by enzyme linked immunosorbent assay (ELISA). Results: Western blot analysis showed that the relative expression of NLRP3 (0.125±0.013 vs. 0.135±0.007) and Cleaved caspase-1 (0.090±0.014 vs. 0.095±0.006) was decreased in the ATV group compared with the control group, but the difference was not statistically significant (P>0.05). The relative expression of NLRP3 (0.315±0.021 vs. 0.135±0.007, P<0.001) and Cleaved caspase-1 (0.235±0.008 vs. 0.095±0.006, P<0.001) was significantly increased in the calcium oxalate crystal stimulation group compared with the control group. While the relative expression of NLRP3 (0.245±0.007 vs. 0.315±0.021, P<0.05) and Cleaved caspase-1 (0.170±0.017 vs. 0.235±0.008, P<0.05) in the ATV treatment group was significantly lower than that in the calcium oxalate crystal stimulation group. The results of immunohistochemical staining showed that the expression trends of NLRP3 and Cleaved caspase-1 in each group were consistent with those obtained by Western blotting. The ELISA results showed that the concentration of inflammatory factors IL-1β [(162.00±21.21)pg/ml vs. (183.50±7.78) pg/ml, P>0.05] and IL-18 [(176.50±24.12)pg/ml vs.(182.50±20.51)pg/ml, P>0.05] in the ATV group was lower than that in the control group, but the difference were not statistically significant (P>0.05). The concentrations of IL-1β[(850.50±48.79)pg/ml vs. (183.50±7.78)pg/ml, P<0.001] and IL-18 [(526.00±39.61)pg/ml vs. (182.50±20.51)pg/ml, P<0.001] were significantly increased in the cell culture medium of the calcium oxalate crystal stimulation group compared with the control group, while the concentrations of IL-1β [(452.50±36.06)pg/ml vs. (850.50±48.79) pg/ml, P<0.01] and IL-18 [(403.50±23.33)pg/ml vs. (526.00±39.61)pg/ml, P<0.05] was significantly reduced in the cell culture medium of the ATV treatment group compared with the calcium oxalate crystal stimulation group. Western blot analysis showed that the relative expression of NF-κB (0.105±0.021 vs. 0.100±0.014) in the ATV group was decreased compared with the control group, but the difference was not statistically significant (P>0.05). The relative expression of NF-κB (0.295±0.035 vs. 0.100±0.014, P<0.001) in the calcium oxalate crystal stimulation group was significantly increased compared with the control group. While the relative expression of NF-κB (0.160±0.012 vs. 0.295±0.035, P<0.05) in the ATV treatment group was significantly lower than that in the calcium oxalate crystal stimulation group. The expression of NF-κB by immunofluorescence staining was consistent with the results of Western blotting. Conclusions Calcium oxalate crystals can induce the inflammatory response of HK-2 cells, while ATV can exert anti-inflammatory effects by inhibiting the activation of NLRP3 inflammasome and decreasing the secretion of inflammatory factors IL-1β, IL-18 and the expression of NF-κB.

Objective? To understand the self-management status among elderly chronic heart failure (CHF) patients and to compare the regional differences of self-management. Methods? By random cluster sampling, we investigated 6 124 elderly CHF patients from 102 hospitals in five regions, East China (Jiangxi Province, Shanghai Municipality, Zhejiang Province), West China (Qinghai Province, Xinjiang Uygur Autonomous Region, Shaanxi Province, Gansu Province, Ningxia Hui Autonomous Region, Yunnan Province), South China (Hainan Province, Guangxi Zhuang Autonomous Region), North China (Heilongjiang Province, Inner Mongolia Autonomous Region), Central China (Henan Province, Hubei Province, Hunan Province). The investigation result statistics were carried out and regional differences were compared. Results? The self-management of elderly CHF patients had a low to medium level with 61.25% (49/80) ＜80% for the scoring rate. The scores of East China and Central China were higher and the score of West China was low; the regional differences were statistical (H=59.07, P＜0.01). The score of diet management was highest with 66.67% for the scoring rate (8/12); East China had the highest score, and West China had the lowest score; the regional differences were statistical (H=92.49, P＜0.01). The scoring rate of medication management was 65.00% (13/20) with the highest in East China and low in North China and West China; the regional differences were statistical (H=351.10, P＜0.01). Mental/social adjustment management was poor with 60.00% (12/20) for the scoring rate; the scores of Ease China were higher than those of North and West China; the regional differences were statistical (H=8.84, P＜0.01). Symptom management was the worst with 57.14% (16/28) for the scoring rate; the scores of East and Central China were high;the regional differences were also statistical (H=17.62,P＜0.01). Conclusions? Self-management of elderly CHF patients needs to be improved. Systematic and targeted health education for different regions should be carried out to improve patients' self-management and to reduce the disease burden.

Objective: To investigate the subjective well-being of gynecologic tumor patients and analyze the influencing factors. Methods: Investigated a total of 411 gynecologic tumor patients by using the a general information questionnaire, Memorial University of Newfoundland Scale of Happiness (MUNSH), Social Support Rating Scale(SSRS) and Medical Coping Modes Questionnaire(MCMQ). Results: The total scores of SWB was (32.20±9.54) points, at a moderate level. The influencing factors of subjective well-being of gynecologic tumor patients included: type of tumor, complication, education, the way of payment for medical treatment, average income per person in family, social support and medical coping modes. Furtherly, average income per person in family, social support and the resigntion dimension of medical coping modes were the main factors. Conclusions The SWB of gynecologic tumor patients need to be improved. To increase the SWB of the patients, the family, society and medical staff should give them more emotional, informational and other kinds of support, and try to minimize negative coping modes such as resigntion.

Objective The aim of this study was to investigate the application of low molecular weight heparin combined with alteplase for thrombolysis in patients with acute myocardial infarction(AMI),and to compare its thrombolysis effect with traditional anticoagulant-general heparin. Methods 35 AMI patients with alteplase intravenous thrombolytic therapy were divided into two groups,among which 15 cases in the study group were treated with 30 mg enoxaparin instant intravenous injection before thrombolysis,40 mg enoxaparin hypodermic injection 15 minutes after thrombolysis,40 mg enoxaparin hypodermic injection every 12 hours for 5 days. The other 20 cases were assigned to the control group and treated with 4 000 u(or 60 u/kg)general heparin instant intravenous injection,then pumped general heparin intravenously in the rate of 800-1 000 u/h. Meanwhile,detected coagulation convention every 3 hours and adjusted the dose of heparin according to the activated partial thromboplastin time(APTT)to keep APTT value within 1.5 to 2.0 times(50-70 s)the standard value. 48 hours later,patients in the control group was given hypodermic injection of 40 mg enoxaparin every 12 hours for 5 days. All cases were given regular treatment as guidelines recommended. Results The patency rate of infarct-related coronary artery assessed by unified clinical criteria was 86.66% and 65.00%,and the average recanalization time was(1.62±0.36)h and(1.81±0.33)h in the study and control groups,respectively. There were no significant differences on patency rate and recanalization time between the two groups(P > 0.05). One case of bleeding complication occurred in the study group(6.66%),while five cases occurred in the control group(25.00%). In the two groups,no cases appeared intracranial hemorrhage and other serious or fatal bleeding occurred. Conclusion The clinical efficacy of low molecular weight heparin was non-inferior to general heparin in AMI patients with alteplas thrombolysis. The application of low molecular weight heparin was simple and easy to operate. It can optimize the procedure of thrombolysis,reduce repetitive coagulation index monitoring and lessen clinical workload,which is worth being promoted to primary hospital and the emergency systems.
