OBJECTIVE: This study evaluated the effectiveness of acupuncture treatment on postoperative pain in patients with degenerative lumbar spine disease, and explored the relationship between the postoperative analgesic effect of acupuncture and the sensation of acupuncture experienced by the patients. METHODS: This retrospective study analyzed the medical records of 97 patients who had undergone an operation by the same surgeon due to degenerative lumbar disease. These patients were divided into acupuncture group (n = 32), patient-controlled analgesia (PCA) group (n = 27), and oral analgesia group (n = 38) according to the different postoperative analgesic methods. During their hospitalization, patients completed daily evaluations of their pain using a visual analogue scale (VAS), and injection times of supplemental meperidine were recorded. Also, the Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) was used in the acupuncture group. RESULTS: Each of the three treatment groups showed significant reductions in postoperative pain, as shown by reduced VAS scores. The acupuncture group, however, had less rebound pain (P < 0.05) than the other two groups. Both the acupuncture and PCA groups experienced acute analgesic effects that were superior to those in the oral analgesia group. In addition, the higher the C-MASS index on the second day after surgery, the lower the VAS score on the fourth day after surgery. There was also a significant difference in the "dull pain" in the acupuncture sensation. CONCLUSION The results demonstrated that acupuncture was beneficial for postoperative pain and discomfort after simple surgery for degenerative spinal disease. It is worth noting that there was a disproportionate relevance between the patient's acupuncture sensation and the improvement of pain VAS score.

Objective:To evaluate the effect of deep learning based on DWI and fluid attenuated inversion recovery (FLAIR) to construct a prediction model of the onset time in acute stroke.Methods:A total of 324 cases of acute stroke with clear onset time, from January 2017 to May 2020 in Nanjing First Hospital, were retrospectively enrolled and analyzed. The patients were divided into a training set of 226 patients and a test set of 98 patients according to the complete randomization method using a 7∶3 ratio, and the patients were divided into ≤ 4.5 h and >4.5 h according to symptom onset time in each group. The acute infarction areas on DWI and the corresponding high signal area on FLAIR were manually outlined by physician. Using the InceptionV3 model as the basic model for image features extraction, the deep learning prediction model based on single sequence (DWI, FLAIR) and multi sequences (DWI+FLAIR) were established and verified. Then the area under curve (AUC), accuracy of human readings, single sequence model and multi sequence model in predicting the acute stroke onset time from imaging were compared.Results:DWI-FLAIR mismatch was found in 94 cases (94/207) of patients with symptom onset time from imaging ≤ 4.5 h, while in 28 cases (28/117) of patients with symptom onset time from imaging >4.5 h. ROC analysis showed that the AUC of DWI-FLAIR mismatch in predicting acute stroke onset time from imaging was 0.607, and the accuracy was 60.2%. The prediction model of deep learning based on single sequence showed that the AUC of FLAIR was 0.761 and the accuracy was 71.4%; the AUC of DWI was 0.836 and the accuracy was 81.6%. The AUC of predicting stroke onset time based on the multi-sequence (DWI+FLAIR) deep learning model was 0.852, which was significantly better than that of manual identification ( Z = 0.617, P = 0.002), FLAIR sequence deep learning model ( Z = 2.133, P = 0.006) and DWI sequence deep learning model ( Z = 1.846, P = 0.012). Conclusion:The deep learning model based on DWI and FLAIR is superior to human readings in predicting acute stroke onset time from imaging, which could provide guidance for intravenous thrombolytic therapy for acute stroke patients with unknown onset time.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Background: Automated peritoneal dialysis (APD) can cater to individual needs, provide treatment while asleep, take into account the adequacy of dialysis, and improve the quality of life. Currently, independent research and development of APD machines made in China are more conducive to patients. A randomized, multicenter, crossover study was conducted by comparing an APD machine made in China with an imported machine. The safety, effectiveness, and manipulability of the two machines were compared. Methods: Two hundred and sixty patients who underwent peritoneal dialysis (PD) on a regular basis in 18 centers between August 2015 and February 2016 were included. The inclusion criteria include age ≥18 years and PD ≥30 days. The exclusion criteria were as follows: hemodialysis; exit site or tunnel infection; and peritonitis ≤30 days. The patients were randomly divided into Group A, who were first treated with a FM machine made in China, then changed to an imported machine; and Group B, who were treated using the reverse sequence. APD treatment was performed with 10 L/10 h and 5 cycles of exchange. After 72 h, the daily peritoneal Kt/V, the accuracy of the injection rate, accuracy of the injection temperature, safety, and manipulability of the machine were assessed. Noninferiority test was conducted between the two groups. Results: The daily peritoneal Kt/V in the APD machine made in China and the imported APD machine were 0.17 (0.14, 0.25) and 0.16 (0.13, 0.23), respectively. There was no significant difference between the groups (Z = 0.15, P = 0.703). The lower limit of the daily Kt/V difference between the two groups was 0.0069, which was greater than the noninferiority value of -0.07 in this study. The accuracy of the injection rate and injection temperature was 89.7% and 91.5%, respectively, in the domestic APD machine, which were both slightly better than the accuracy rates of 84.0% and 86.8% in the imported APD machine (89.7% vs. 84.0%, P = 0.2466; 91.5% vs. 86.8%, P = 0.0954). Therefore, the APD machine made in China was not inferior to the imported APD machine. The fuselage of the imported APD machine was space-saving, while the APD machine made in China was superior with respect to body mobility, man-machine dialog operation, alarm control, and patient information recognition. Conclusions: The FM machine made in China was not inferior to the imported APD machine. In addition, the FM machine made in China had better operability.

Objective To study the effects of ribosomal protein L41 (RPL41) on the proliferation and apoptosis of human retinoblastoma Y79 cells and its underlying mechanisms.Methods Y79 cells were seeded in RPMI 1640 medium containing 10％ fetal bovine serum for passage culture.Then the cells were divided into control group,with cells left untreatment,(40 μmol · L-1,80 μmol · L 1 and 120 μmol · L-1) RPL41 treatment group according to the concentration.Next CellTiter-Glo fluorescence cell viability testing system was used to observe the viability of Y79 cells in all groups,and flow cytometry was applied to measure the cell apoptotic rate in 100 μmol · L 1 RPL41 treatment group,with Hoechst staining for the observation of nuclear morphometry of apoptotic cells,and finally,Western blot was used to determine the expression of activating transcription factor 4 (ATF4) of each group.Results Compared with the control group,the viability of Y79 cells in the 40 μmol · L-1 RPL41 treatment group was (97.9 ± 1.5) ％,with no significant difference (P =0.055);and the viability in the 80 μmol · L-1 and 120 μmol · L-1 RPL41 treatment group was (87.6 ± 1.8)％ and (63.9 ± 2.0) ％,respectively,both of which were significantly different from the control group (both P ＜ 0.05),so RPL41 inhibited the viability of Y79 cells,and 100 μmol · L-1 RPL41 promoted the apoptosis of Y79 cells,with the apoptotic rate of (17.33 ± 2.47)％.Compared with normal cells,the apoptotic cells in the 100 μmol · L 1 RPL41 treatment group showed bright color and smaller cell volume by Hoechst staining.Western blot showed that PRL41 significantly decreased the expression of ATF4 protein and the expression of ATF4 protein in the 40 μmol · L 1,80 μmol · L-1 and 120 μmol · L 1 treatment group were 0.76 ± 0.04,0.29 ± 0.04,0.29 ± 0.05,respectively,all of which were significantly different from the control group (all P ＜ 0.01).Conclusion RPL41 can inhibit the proliferation and promote the apoptosis of human retinoblastoma Y79 cell,and its mechanism may be related to the expression of ATF4.

Objective To explore the correlation between the level of serum homocysteine (Hcy) and the thickness of retinal ganglion cell layer (GCL) on optical coherence tomography (OCT) in patients with type 2 diabetes.Methods Totally 60 diabetic patients were collected from October 2016 to October 2017 in the Shengjing Hospital of China Medical University,and they were divided into two groups:diabetic patients without retinopathy (NDR group,n =30) and non-proliferative diabetic retinopathy group (NPDR group,n =30) according to the ETDRS classification,and meanwhile additional 30 healthy subjects were enrolled as control group.The level of serum Hcy was detected,and the retinal GCL thickness was measure using OCT in all patients for the analysis of the correlation of serum Hcy level with the thickness of GCL.Results The serum Hcy level was (11.87 ± 2.19) nmol · L-1 in the control group,(14.87 ± 0.42)nmol · L-1 in the NDR group and (20.77 ± 2.40) nmol · L-1 in the NPDR group,which was significantly increased gradually,and the difference was statistically significant (P =0.000),but the thickness of GCL was (88.33 ± 6.36) μm,(81.73 ± 1.41) μm and (64.00 ± 12.73) μm in the three groups,accordingly,which was decreased significantly gradually,with statistically significant difference (P =0.000).Along with the progress of fundus lesions,the level of serum Hcy increased,but the thickness of GCL decreased,and there was a significant negative correlation of the serum Hcy level with the thickness of GCL in the retina by Pearson (r =-0.908,P =0.000).Conclusion The increase of serum Hcy level in diabetic patients is associated with the decrease of retinal GCL thickness,and Hcy is involved in neurodegenerative changes in patients with diabetic retinopathy.

OBJECTIVETo study the effect of aqueous extract of several kinds of herbs on human platelet aggregation and expression of P-selectin in vitro.

METHODSBlood was collected from volunteers. Effects of the prepared water extracts of herbs on platelet aggregation were monitored on a Packs-4 aggregometer. The fluorescence intensity of water extracts of Caulis Spatholobi, Flos Carthami and Rhizoma Curcumae on the expression of P-selectin in human platelets of healthy persons was measured with flow cytometry.

RESULTSOut of several herbs investigated, Flos Carthami and Rhizoma Curcumae potently inhibited platelet aggregation after incubation with platelet-rich plasma (PRP) for 15 min. Caulis Spatholobi Flos Carthami and Rhizoma Curcumae inhibited adenosine-5'-diphosphate (ADP) or platelet activating factor (PAF)-induced platelet aggregation in PRP in a dose-dependent manner. In contrast to Flos Carthami and Rhizoma Curcumae, Caulis Spatholobi could not inhibit thrombin-induced platelet aggregation. Despite its inability to inhibit thrombin-induced platelet aggregation in PRP, Caulis Spatholobi had a greater anti-aggregating activity in PRP induced by ADP or PAF. Caulis Spatholobi and Flos Carthami showed significant inhibitory effects on the expression of P-selectin.

CONCLUSIONSCaulis Spatholobi, Flos Carthami and Rhizoma Curcumae have potent anti-platelet properties, and their inhibitory actions are mediated via different mechanisms. Caulis Spatholobi inhibited ADP-induced platelet aggregation but not by thrombin, indicating that its mechanism of action might be independent of the thromboxane pathway. The effect of Caulis Spatholobi and Flos Carthami were associated with suppressing the expression of P-selectin.

This study was purposed to investigate the changes of von Willebrand factor cleaving protease (ADAMTS13) activity and vWF antigen level in patients with acute myelogenous leukemia (AML) before and after treatment and evaluate their clinical significance. Seventy-three AML patients were enrolled in this study, the sodium citrate anticoagulated plasma was collected before and after their induction chemotherapy. Fluorescence resonance energy transfer substrate vWF73 (FRETS-vWF73) assay was established to detect the plasma ADAMTS13 activity while vWF antigen level was measured by ELISA. The results showed that the ADAMTS13 activity in newly diagnosed patients with AML before induction therapy was obviously lower than that in normal controls (63.3 ± 25.5)% vs (105.1 ± 37.7)(P < 0.01), while the vWF antigen level was higher than that in normal controls (226.6 ± 127.0)% vs (111.4 ± 39.7)% (P < 0.01). After standard induction chemotherapy, the ADAMTS13 activity of AML patients in complete remission period was higher than that in AML patients before therapy (P < 0.01), and was not significant difference with that in normal controls; the vWF antigen was significantly lower than that in AML patients before therapy (P < 0.01), but it still was higher than that in controls (P < 0.05). The ADAMTS13 activity in newly diagnosed AML patients complicated with infection before therapy was obviously lower than that in AML patients without infection (52.2 ± 20.6)% vs (73.9 ± 24.7)% (P < 0.01), while the vWF antigen level was significantly higher than that in AML patients without infection (262.2 ± 135.7)% vs (193.8 ± 110.2)% (P < 0.05). The ADAMTS13 activity in AML patients with disseminated intravascular coagulation (DIC) was significantly lower than that in AML patients without DIC (42.0 ± 14.5)% vs (73.4 ± 22.7)% (P < 0.01), while the vWF antigen level was obviously higher that in AML patients without DIC (274.2 ± 140.0)% vs (204.7 ± 115.5)% (P < 0.01). It is concluded that the ADAMTS13 activity in newly diagnosed AML patients befor induction therapy has been confiremed to be lower and the vWF antigen level to be higher, especially in AML patients with infection or DIC. The ADAMTS13 and vWF antigen may play a role in the pathogenesis of AML and the formation of infection and DIC.

OBJECTIVETo investigate the early prognostic values of arterial lactate and base excess (BE) in patients with paraquat poisoning.

METHODSSeventy-five patients with paraquat poisoning were divided into sudden death group (n = 10) who died within 24 h after admission, recent death group (n = 31) who died more than 24 h after admission, and survival group (n = 34). Arterial lactate and BE were measured on admission and at 24 h after admission. The prognostic values of arterial lactate and BE were analyzed.

RESULTSThe arterial lactate measured on admission was significantly higher in the sudden death group than in the recent death group and survival group (P < 0.01), but there was no significant difference in arterial lactate between the recent death group and survival group (P = 0.309). The BE measured on admission was significantly lower in the sudden death group than in the recent death group and survival group, and it was significantly lower in the recent death group than in the survival group (P < 0.01 or P < 0.05). At 24 h after admission, the recent death group had a significantly higher arterial lactate (P < 0.01) and a significantly lower BE (P < 0.01), as compared with the survival group. The logistic regression analysis showed that the two indices were significantly associated with prognosis (P < 0.01). On admission, the areas under the receiver operating characteristic (ROC) curve (AUCs) of arterial lactate and BE for predicting death were 0.692 and 0.787, respectively, and the cut-off values were 3.25 mmol/L and -1.75 mmol/L, respectively; the AUCs of arterial lactate and BE for predicting sudden death were 0.995 and 1, respectively, and the cut-off values were 7.1 mmol/L and -12.8 mmol/L, respectively. At 24 h after admission, the AUCs of arterial lactate and BE for predicting death were 0.743 and 0.822, respectively, and the cut-off values were 2.15 mmol/L and -5.55 mmol/L, respectively.

CONCLUSIONArterial lactate and BE have certain values in predicting the death, especially the sudden death, in patients with acute paraquat poisoning.
