BACKGROUND: Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS: Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS: We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION: The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

Sialidosis is a rare lysosomal storage disease caused by NEU1 gene mutation at 6p21.33. It is characterized by myoclonic, ataxia, epilepsy, and decreased vision. A pair of twins with sialidosis type 1 are reported to enrich clinicians ′ understanding of the disease, so as to improve the diagnosis and treatment. The proband was a 16-year-old male. The main symptom was intermittent limb involuntary trembling for 2 years, with paroxysmal loss of consciousness. Fundus examination showed cherry-red spots. His twin brother had similar symptoms, but the overall performance was mild. Whole exome sequencing results showed that both patients carried compound heterozygous mutations of c.239C>T (p.P80L) and c.803A>G (p.Y268C) in NEU1 gene, which were from their normal phenotype mother and father.

To find an effective method of minimally invasive treatment combining prevention and assistance in the middle zone of conservative treatment and fusion surgery for lumbar degenerative diseases, through the clinical effect observation and the advantage and disadvantage comparison of several commonly used lumbar interspinous dynamic stabilization systems, by analyzing the physiological structure, biomechanics and relevant data of lumbar interspinous processes, based on fully understanding of memory alloy materials, a new dynamic lumbar interspinous fixation device with a memory alloy material has been independently designed and researched, which can not only reconstruct the normal biomechanical characteristics of the lumbar spine and satisfy the normal activities of the human spine, but also avoid damage to the original structure and reduce the incidence of postoperative complications. In addition, the device can be used to optimize the current therapeutic methods. According to our research, the dynamic lumbar interspinous process stabilization device with a memory alloy has theoretically achieved satisfactory results, which can be used to overcome the shortcomings of the existing technology and is superior to the current several dynamic lumbar interspinous process stabilization systems.

Objective:To evaluate the early diagnostic value of tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) and insulin-like growth factor binding protein-7 (IGFBP-7) in acute kidney injury induced by sepsis.Methods:A total of 85 sepsis patients admitted to the EICU and GICU in Shanghai East Hospital from September 2017 to June 2019 were divided into theAKI group ( n=37) and the non-AKI group ( n=48) according to KIDGO diagnostic criteria, and 20 healthy volunteers were served as the control group. The clinical data were recorded and samples of urine were collected at 0 h, 6 h, 12 h, 1 d, 3 d and 7 d post sepsis. The levels of TIMP-2 and IGFBP-7 in the urine were analyzed with ELISA at different time points. Based on the receiver operating characteristic curve (ROC) and the area under the curve (AUC), the early diagnostic value of urinary TIMP-2 and IGFBP-7 in sepsis-induced AKI patients was determined. Results:Compared with the control group, the levels of TIMP-2 and IGFBP-7 of the AKI group were significantly higher at the above time points ( P<0.05), while those of the non-AKI group showed no significant differences. The levels of TIMP-2 and IGFBP-7 of the AKI group were significantly higher than the those of the non-AKI group ( P<0.05). ROC analysis showed that when the AUC of urine TIMP-2 peaked at 1 d, the sensitivity and specificity reached 97.5% and 81.2%, separately with the cutoff value of 151.23 ng/mL. Furthermore, when the AUC of urine IGFBP-7 peaked at 12 h, the sensitivity and specificity reached 100% and 72.8%, separately with the cutoff value of 14.91 ng/mL. Interestingly, when the AUC of combined TIMP-2×IGFBP-7 peaked at 12 h, the sensitivity reached 98.0% and specificity reached 91.5% with the cutoff value of 2.09 [(ng/mL) 2/1 000]. There was no significant correlation between the levels of TIMP-2 and IGFBP-7 with SOFA and APACHEⅡ score at 1 d, 3 d and 7 d post sepsis in the AKI group ( P>0.05). Conclusions:Urine TIMP-2 and IGFBP-7 have early diagnostic value in sepsis-induced AKI. Besides, the combination of the two biomarkers have superior predictive value than each single of them.

Understanding the effect of immunosuppressive agents on intestinal microbiota is important to reduce the mortality and morbidity from orthotopic liver transplantation (OLT). We investigated the relationship between the commonly used immunosuppressive agent cyclosporine A (CSA) and the intestinal microbial variation in an OLT model. The rat samples were divided as follows: (1) N group (normal control); (2) I group (isograft LT, Brown Norway [BN] rat to BN); (3) R group (allograft LT, Lewis to BN rat); and (4) CSA group (R group treated with CSA). The intestinal microbiota was assayed by denaturing gradient gel electrophoresis profiles and by using real-time polymerase chain reaction. The liver histopathology and the alanine/aspartate aminotransferase ratio after LT were both ameliorated by CSA. In the CSA group, the numbers of rDNA gene copies of Clostridium cluster I, Clostridium cluster XIV, and Enterobacteriaceae decreased, whereas those of Faecalibacterium prausnitzii increased compared with the R group. Cluster analysis indicated that the samples from the N, I, and CSA groups were clustered, whereas the other clusters contained the samples from the R group. Hence, CSA ameliorates hepatic graft injury and partially restores gut microbiota following LT, and these may benefit hepatic graft rejection.

OBJECTIVE: To determine the incidence of surgical site infection (SSI) after abdominal surgery and to further evaluate the related risk factors of SSI in China. METHODS: The multicenter cross-sectional study collected clinical data of all adult patients who underwent abdominal surgery from May 1, 2018 to May 31, 2018 in 30 domestic hospitals, including basic information, perioperative parameters, and incisional microbial culture results. The primary outcome was the incidence of SSI within postoperative 30 days. SSI was classified into superficial incision infection, deep incision infection, and organ/gap infection according to the US Centers for Disease Control and Prevention (CDC) criteria. The secondary outcome variables were ICU stay, postoperative hospital stay, total hospital stay, 30-day mortality and treatment costs. Multivariate logistic regression was used to analyze the risk factors of SSI. RESULTS: A total of 1666 patients were enrolled in the study, including 263 cases of East War Zone Hospital of PLA, 140 cases of Affiliated Hospital of Qingdao University, 108 cases of The First Affiliated Hospital of Nanchang University, 87 cases of Central War Zone Hospital of PLA, 77 cases of West China Hospital, 74 cases of Guangdong General Hospital, 71 cases of Chenzhou First People's Hospital, 71 cases of Zigong First People's Hospital, 64 cases of Zhangjiagang First People's Hospital, 56 cases of Nanyang City Central Hospital, 56 cases of Lanzhou General Hospital of Lanzhou Military Command, 56 cases of Shandong Provincial Hospital, 52 cases of Shangqiu First People's Hospital, 52 cases of People's Hospital of Xinjiang Uygur Autonomous Region, 48 cases of The Second Xiangya Hospital of Central South University, 48 cases of Chinese PLA General Hospital, 44 cases of Affiliated Hospital of Xuzhou Medical University, 38 cases of Hunan Province People's Hospital, 36 cases of Dongguan Kanghua Hospital, 30 cases of Shaoxing Central Hospital, 30 cases of Northern Jiangsu People's Hospital, 29 vases of The First Affiliated Hospital of Zhengzhou University, 27 cases of General Hospital of Tianjin Medical University, 22 cases of Zigong Fourth People's Hospital, 21 cases of The Second Hospital of University of South China, 18 cases of Tongji Hospital, 15 cases of Nanchong Central Hospital, 12 cases of The 901th Hospital of PLA, 11 cases of Hunan Cancer Hospital, 10 cases of Lanzhou University Second Hospital. There were 1019 males and 647 females with mean age of (56.5±15.3) years old. SSI occurred in 80 patients (4.8%) after operation, including 39 cases of superficial incision infection, 16 cases of deep incision infection, and 25 cases of organ/interstitial infection. Escherichia coli was the main pathogen of SSI, and the positive rate was 32.5% (26/80). Compared with patients without SSI, those with SSI had significantly higher ICU occupancy rate [38.8%(31/80) vs. 13.9%(220/1586), P<0.001], postoperative hospital stay (median 17 days vs. 7 days, P<0.001) and total hospital stay (median 22 days vs. 13 days, P<0.001), and significantly higher cost of treatment (median 75 000 yuan vs. 44 000 yuan, P<0.001). Multivariate analysis showed that male rise(OR=2.110, 95%CI:1.175-3.791, P=0.012), preoperative blood glucose level rise(OR=1.100, 95%CI: 1.012-1.197, P=0.026), operative time (OR=1.006, 95%CI:1.003-1.009, P<0.001) and surgical incision grade (clean-contaminated incision:OR=10.207, 95%CI:1.369-76.120, P=0.023; contaminated incision: OR=10.617, 95%CI:1.298-86.865, P=0.028; infection incision: OR=20.173, 95%CI:1.768-230.121, P=0.016) were risk factors for SSI; and laparoscopic surgery (OR=0.348, 95%CI:0.192-0.631, P=0.001) and mechanical bowel preparation(OR=0.441,95%CI:0.221-0.879, P=0.020) were protective factors for SSI. CONCLUSIONS The incidence of postoperative SSI in patients with abdominal surgery in China is 4.8%. SSI can significantly increase the medical burden of patients. Preoperative control of blood glucose and mechanical bowel preparation are important measures to prevent SSI.

Objective: To evaluate the anti- herpes simplex virus type 1 (HSV-1) activity of KPC-rg1, a water extract from Cinnamomum cassia, and explore its potential function of broad-spectrum antivirus effect. Methods: In vitro, the changes of morphology of Vero cells were assessed and viral loads were detected after cells were infected with HSV-1 alone and HSV-1 pre-treated with KPC-rg1 respectively. The corneal lesions of mouse and tree shrew corneal infection model were evaluated after they were infected with HSV-1 alone and HSV-1 pre-treated with KPC-rg1 respectively. The antiviral activity of KPC-rg1 against 9 viruses were measured by CPE and GFP reduction assays. Results: The virus replication of HSV-1 infected cells was moderately inhibited by KPC-rg1 in a dose range of 0.0001-1.0 mg/ml, while the cells were completely protected when they were infected with HSV-1 pre-treated with KPC-rg1 (0.001-1.0 mg/ml). The corneal lesions of animals were improved in both mouse and tree shrews models infected with HSV-1 after the treatment of KPC-rg1, while animals were completely protected from infection when HSV-1 pre-treated with KPC-rg1. KPC-rg1 had a potential anti-virus effect on the enveloped viruses such as HSV-1, HCMV, RSV alone and HIV-1. Conclusions KPC-rg1 is a collosol (Tyndall effect) which would immediately form a stable super-nanoparticle structure of KPC-rg1/virus when encounter virus, and thus the virus coated by KPC-rg1 lost its ability of infection. KPC-rg1 can reduce the suffering by newly or latent virus infection because its encapsulation of virus and inhibition of further infection. Our study added additional proofs of the anti-viral property of the water extract from Cinnamomum cassia, and provided a further basis to develop KPC-rg1 as a drug which could be potentially applied in clinic to treat HSV-1 infection.

Objective: To evaluate whether the self-designed single-channel intracavitary applicator yields equivalent clinical efficacy and safety to the standard Fletcher-type three-channel applicator in the high-dose-rate (HDR) brachytherapy for uterine cervical cancer. Methods: From December 2011 to April 2017, patients initially diagnosed with cervical cancer were randomly assigned into the external beam radiotherapy (EBRT)+ single-channel intracavitary applicator group (the patent single-channel group) and EBRT+ the Fletcher applicator group. Whole pelvis irradiation was delivered with 6-MV photons via a four-field box variant or anterior and posterior parallel fields. Five to six fractions of intracavitary brachytherapy were performed at a dose of 7 Gy at point A once a week after 30 Gy (BED at point A: 80-90 Gy). Chemotherapy was given with intravenous injection of cisplatin at a dose of 40 mg/m² once weekly during EBRT.Clinical efficacy and safety were evaluated after the treatment. Results: In total, 150 eligible cases were assigned into the Fletcher applicator group and 149 cases into the patent single-channel group. The short-term clinical efficacy and acute toxicity did not significantly differ between two groups. The response rate was 94.0% in the Fletcher group, and 94.7% in the patent single-channel group. In the Fletcher applicator group, 76(50.7%) patients developed ≥ grade 3 hematologic toxicity and 61(40.9%) in the patent group (P=0.195). Conclusions: The self-designed patent single-channel intracavitary applicator yields equivalent clinical efficacy and safety (acute toxicity) to the standard Fletcher-type three-channel applicator in the HDR brachytherapy for uterine cervical cancer.

Objective To evaluate the clinical efficacy of intra-articular injection of ozone in collagen-induced arthritis (CIA) rats and to assess its effects on serum receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG) levels. Methods Forty weight age malched Wistar rats were randomly divided into normal control group (normal group), the CIA model group (CIA group), ozone (O 3 group), and methotrexate (MTX group). In addition to the normal control group, Freund's complete adjuvant and bovine type Ⅱ collagen were injected to establish the rat model of CIA. After the model was sucessfully developed, double ankle injection concentration ozone group of 40 μg/ml of O3 each 1 ml, 1 times a week, a total of injection for 3 weeks for the experimenal group. MTX group of 0.9 mg/kg was injected 1 times a week for 3 weeks for the MTX group. Degree of foot swelling was measured, and radiographic assessment of arthritis index (AI) score was performed. One week after treatment, angular vein blood was collected for the rats after the intervention, flow multi-factor detection technology was used to test each rat. T test or Wilcoxon rank test was used to compare the difference between groups. Results ① After 3 week administration with O3, dcgree of foot swelling, and AI of the O3 group was reduced significanly than the CIA group during the same period (foot swelling degree: O3 group: (4.21±0.14) ml, CIA group (9.12±0.17) ml, T=64.08, P=0.00; AI O3 group: [(2.97± 0.18) ml, CIA group: 5.76 ±0.13, T=37.24, P=0.00], and X-ray showed joint damage was alleviated. ② The serum level of RANKL in the CIA group was significantly higher than of the normal group [CIA model group 1890.70(797.03, 10571.94)], normal group [74.46(29.21, 95.37), T=43, P=0.005] during the same period; The serum level of RANKL in the O3 group was significantly lower than the CIA group [O3 group 28.09 (14.11, 207.30), CIA group 1890.70 (797.03, 10571.94), T=39, P<0.05]; RANKL level of the Ozone group when compared with MTX group, was not statistically significantly difference (T=52, P>0.05).③Serum RANKL/OPG of the CIA group was significantly higher than that of the normal group during this period, the difference was statistically significant [CIA group 250.68(42.33, 2959.78), normal group 4.32(3.16,5.30), T=36, P<0.01);The serum level of RANKL/OPG in the O3 group was significantly lower than the CIA group [O3 treatment group 5.10 (3.38, 6.64), CIA group 250.68 (42,33, 2959.78), T=36, P<0.01]; There was no statistically significant difference of the serum RANKL/OPG between the O3 group and the MTX group (T=62.5, P>0.05). Conclusion Intra-articular injection of concentration of 40 μg/ml of O3 can reduce RA rat joint swelling degree, which may relate to the mechanism that O3 can lower levels of serum RANKL and RANKL/OPG ratio, reduce osteoclast formation and activation.
