Objective To observe the clinical efficacy of butylphthalide soft capsules for treatment of acute cerebral infarction and its effect on the neurological function and inflammatory reaction of patients.Methods A total of 100 patients with acute cerebral infarction in the First Hospital of Zhangjiakou City and the Third Hospital Affiliated to Hebei North University from January 2016 to October 2016 were selected and divided into control group (n =50) and treatment group (n =50) according to the treatment protocols.The patients in the control group were given anti-platelet aggregation,statins,and other routine treatment;based on this,the patients in treatment group were orally administrated with butylphthalide soft capsules.The elbow venous blood of patients in the two groups was collected and the C reactive protein(CRP),interleukin-6 (IL-6) levels,the platelet aggregation rate were detected.The change of National Institute of Health stroke scale(NIHSS) score of patients after four weeks treatment was compared between the two groups.The recovery of neurological function of patients in the two groups was evaluated by modified Rankin grading after three months treatment.Results There was no statistic difference in the CRP,IL-6 levels and platelet aggregation rate before treatment between the two groups (P ＞ 0.05).The CRP,IL-6 levels and platelet aggregation rate of patients in the two groups after one week treatment were significantly lower than those before treatment (P ＜ 0.05);and the CRP,IL-6 levels and platelet aggregation rate of patients in the treatment group were significantly lower than those in the control group after one week treatment (P ＜ 0.05).The NIHSS score of patients in the treatment group was significantly lower than that in the control group after four weeks treatment (P ＜ 0.05);the Rankin score of patients in the treatment group was significantly lower than that in the control group after three months treatment (P ＜ 0.05).The total effective rate of patients in the treatment group was significantly higher than that in the control group (x2 =13.22,P ＜ 0.05).Conclusion Butylphthalide soft capsules can significantly reduce the inflammatory reaction in patients with acute cerebral infarction,improve and recover the neurologic impairment;and its curative effect is remarkable.

Objective To investigate the relationship between the effect of high mobility group protein box 1 (HMGBI) on the renal injure of systemic lupus erythematosus (SLE) and the expression of Toll-like receptor 4(TLR4). Methods The level of HMGB1, MMP-2 and TIMP-2 in serum from 16 pa-tients with SLE, 18 patients with lupus nephritis(LN) and 12 healthy people were measured by ELISA. The fresh peripheral blood mononuelear cell (PBMC) were isolated and the total RNA was extracted. Then the mRNA expression of HMGB1 was amplified by RT-PCR. Flow cytometry analysis was performed to study cell surface markers and the expression of TLR4. Results RT-PCR and ELISA results showed that the expres-sions of mRNA and level of HMGB1 protein in serum were higher in patients with LN than those in SLE and healthy people. The expression of TLR4 in CD14+ monecytes of patients with LN was higher than that with SLE and healthy people, while there were no significance in CD3+ T cells among LN, SLE and healthy peo-ple. The expressions of MMP-2 and TIMP-2 in serum of LN was lower than that in SLE and healthy people, at the same time the ratio of MMP-2/TIMP-2 decreased in LN group. HMGB1 mRNA and CD14+/TLR4+ was negatively correlated with the ratio of MMP-2/TIMP-2, and the level of HMGB1 in serum was positively correlated with proteinuria, while negatively correlated with the ratio of MMP-2/TIMP-2 in LN. Conclusion HMGB1 is one of the important cytokine in the pathogenesis of lupus nephritis. HMGBI might play a role in proteinuria of lupus nephritis in part via TLR4 pathway to activate monocytes and decrease the expression of MMP-2/TIMP-2.

Objective To analyze the clinical value of 16-row multislice CT in the live kidney donor preoperative assessment. Methods Thirty-six kidney donors underwent 16-slice CT preopera-tive assessment. The non-enhanced, arterial phase, venous phase and excretory phase examinations were performed. Two radiologists independently studied renal vessels and urinary system of each case by maximum intensity projections and volume rendering techniques. The specificity and accuracy of 16-row muhislice CT in the evaluation o{ renal vessels and urinary system were calculated after comparing with surgical findings as reference. Results 16-row muhislice CT found 7 variant renal arteries. One variant artery confirmed in surgery was missed in the CT study. 16-row muhislice CT made cor-rect diagnosis of all variant anatomy of renal veins and ureters which were confirmed in surgery. For i-dentification of variant anatomy of renal arteries, veins and ureters, the specificity of 16-slice CT was 100% (29/29), 100% (32/32), and 100% (35/35), the overall accuracy was 97%(36/37), 100% (36/ 36), and 100%(36/36), respectively. Conclusions 16-row muhislice CT shows excellent value in the evaluation of renal vessels and urinary system in live kidney donors. 16-row multislice CT is suit-able for the noninvasive examination in live kidney donor preoperative assessment and provides all sup-portive and relevant information required by the surgeons.

Objective:To investigate the expression and mechanism of NF-κB signal pathway in murine lupus nephritis.Methods:The BXSB mice as well as C57BL/6 of 16 weeks were used.Transmission electron microscope and PAS were used to detect the pathological change of renal tissue.RT-PCR and ELISA were used to detect the expression of HMGB1 mRNA and protein.The expression of HMGB1,p- NF-κB,RAGE,IκB and PCNA protein was detected by immunohistochemical stain,FCM and Western blot.Results:The level of BUN in serum and Micro-albumin in urine of BXSB mice was higher than that in C57BL/6 mice.The expression of HMGB1 mRNA and HMGB1 protein level in peripheral blood increased significantly in BXSB group.Compared with those in control group,electron microscopy and PAS revealed the thickness of glomerular basement membrane(GBM),fusion of foot processes partly of epithelial dell and subepithelial electron-dense deposits in the renal tissue of BXSBA mice.Compared with that of control group,expression of PCNA was higher in glomeruli of BXSB mouse.HMGB1 protein over-expression localized in cytoplasm and extracellular milieu,especially in proliferative glomeruli in BXSB group,while the HMGB1 protein primarily confined to the nuclear of tubule in control group.In BXSB group,the expression of p-NF-κB and RAGE increased,while the expression of IκB decreased.There were positive correlation between the expression of HMGB1,RAGE and p-NF-κB protein (r=0.833,0.621,0.848,P＜0.01),while the expression of p-NF-κB protein negatively correlated with that of IκB.Conclusion:HMGB1 could activate NF-κB through combining with its receptor-RAGE,induce the form of proliferative glomerulonephritis by promoting the proliferation of inherent cell of glomeruli,which may play an important role in the murine lupus nephritis.

Objective:To analyze the diagnostic and prognostic values of the red blood cell distribution width-to-platelet count ratio (RPR) for hepatitis B and liver cirrhosis.Methods:The clinical data of 80 patients with hepatitis B and liver cirrhosis who were diagnosed and treated in Yiwu Central Hospital from June 2020 to August 2021 were retrospectively analyzed. These patients were included in the hepatitis B and liver cirrhosis group. They were subdivided into survival ( n = 69) and death ( n = 11) groups according to their prognosis outcomes. Eighty patients with chronic hepatitis B were included in the chronic hepatitis B group. Eighty healthy controls who concurrently underwent physical examination were included in the control group. The diagnostic and prognostic values of RPR, aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis index based on four factors (FIB-4) for hepatitis B and liver cirrhosis were analyzed. Results:Red blood cell distribution width, alanine transaminase, and aspartate transaminase in the hepatitis B and liver cirrhosis group and chronic hepatitis B group were significantly higher compared with the control group (all P < 0.05). Platelet count in the hepatitis B and liver cirrhosis group and chronic hepatitis B group was significantly lower than that in the control group (both P < 0.05). Red blood cell distribution width in the hepatitis B and liver cirrhosis group was significantly higher than that in the chronic hepatitis B group [(18.25 ± 3.28)% vs. (14.67 ± 2.15)%, t = 8.16, P < 0.05]. Platelet count, alanine transaminase, and aspartate transaminase levels in the hepatitis B and liver cirrhosis group were (78.47 ± 11.43) × 10 9/L, (49.48 ± 6.85) U/L, (45.86 ± 6.28) U/L, respectively, which were significantly lower than (133.36 ± 18.42) × 10 9/L, (128.36 ± 15.40) U/L, (98.67 ± 14.41) U/L in the chronic hepatitis B group ( t = -22.65, -41.86, -30.05, all P < 0.05). PRP, APRI, and FIB-4 in the hepatitis B and liver cirrhosis group were (0.23 ± 0.05), (1.85 ± 0.44), (4.25 ± 0.81) respectively, which were significantly higher than (0.11 ± 0.02), (1.46 ± 0.33), (3.38 ± 0.63) in the chronic hepatitis B group ( t = 19.93, 6.34, 7.58, all P < 0.001). The RPR, APRI, and FIB-4 in the death group were (0.25 ± 0.08), (1.97 ± 0.48), (4.52 ± 1.31), respectively, which were significantly higher than (0.18 ± 0.05), (1.68 ± 0.40), (3.69 ± 1.21) in the survival group ( t = 3.94, 2.17, 2.09, all P < 0.05). The receiver operating characteristic curve revealed that PRP has an extremely high value in diagnosing hepatitis B and liver cirrhosis and predicting the death of patients with hepatitis B and liver cirrhosis. Conclusion:RPR has an extremely high value in diagnosing hepatitis B and liver cirrhosis and predicting the prognosis of this disease.

Objective:To investigate whether the bladder neck descent and the area of levator ani hiatus obtained on the maximum Valsalva were consistent at the lithotomy position and separating-legs-holding-knees position.Methods:Forty four subjects who underwent perineal pelvic floor four-dimensional ultrasound at 6-8 weeks postpartum in Third Hospital of Longgang Shenzhen from November 2019 to January 2020 were enrolled in this study. All subjects were able to effectively complete the maximum Valsalva maneuver both at the lithotomy position and the separating-legs-holding-knees position. The bladder neck descent and hiatus area of the levator Ani on the maximum Valsalva at these two positions were measured and compared.Results:The bladder neck descent at the separating-legs-holding-knees position was higher than that at the lithotomy position [(41.06±8.25)mm vs (39.96±8.10)mm; t=-2.965, P=0.005], and the hiatus area of levator Ani at the separating-legs-holding-knees position was larger than that at the lithotomy position[(27.55±4.90)cm 2 vs (26.32±4.76)cm 2; t=-3.820, P<0.001]. Conclusions:The bladder neck descent and the area of levator Ani hiatus on the maximum Valsalva at separating-legs- holding-knees position are larger than those on the maximum Valsalva at the lithotomy position.

ObjectiveTo investigate the possible mechanism of compound Yinqi Sanhuang Jiedu Decoction （茵芪三黄解毒汤， YSJD） against the progression of hepatic fibrosis （HF）. MethodsThirty-eight C57BL/6J mice were randomly divided into blank group， model group， silybin group and low-， medium- and high-dose YSJD groups， with eight mice in the model group and six mice each in other groups. Except for the blank group， all mice were injected intraperitoneally with 10% carbon tetrachloride （CCl₄） to establish a HF model， twice a week for 8 weeks. The drug intervention started one week after the first modeling； the low-， medium- and high-dose YSJD groups were given 8.325， 16.65 and 33.3 g/（kg·d） of YSJD suspension by gavage， respectively， while the silybin group was given 55 mg/（kg·d） of silybin suspension by gavage， and the blank group and the model group were given 0.2 ml normal saline by gavage， all for 8 weeks. The liver hardness of living mice was observed using a small animal ultrasound detector， and grey-scale ultrasound was recorded. The liver tissue was observed by Sirius scarlet staining， and the proportion of collagen fiber deposition was calculated. Liver function indicators including alanine aminotransferase （ALT） and aspartate aminotransferase （AST）， and serum laminin （LN）， hyaluronic acid （HA）， pre-collagen type III （PCIII） and collagen type IV （CIV） were also detected. The protein expression of transforming growth factor β1 （TGF-β1）， Vimentin， E-cadherin， α smooth muscle actin （α-SMA） in liver tissue were detected. ResultsCompared to the blank group， the model group showed increased gray value， collagen deposition，serum ALT， AST， HA， LN and PCIII levels， decreased expression of E-cadherin， and increased expression of N-cadherin，α-SMA，Vimentin and TGF-β1 in liver tissues （P＜0.05）. Compared to the model group， the ultrasonic gray value and the proportion of collagen fiber deposition in liver of silybin group and YSJD medium- and high-dose groups decreased， and the serum ALT， AST， LN， HA and PCⅢ levels decreased. Compared to the model group， the expression of E-cadherin in liver tissues of silybin group and all three YSJD groups increased， while the expressions of N-cadherin， Vimentin， TGF-β1 and α-SMA decreased （P＜0.05）， and among them， most improvements were seen in the medium-dose YSJD group （P＜0.05）. ConclusionThe effect of YSJD on significantly reducing the extent of HF in mice caused by CCl₄ may be related to its ability to regulate liver hardness and inhibit the occurrence of epithelial mesenchymal transition in mice.

Nonalcoholic fatty liver disease （NAFLD） is an abnormal lipid metabolic disorder of the liver characterized by accumulation of a large amount of lipids in the liver， and it is currently the most common liver disease around the world. Mendelian randomization （MR） incorporates genomic data into traditional epidemiological study designs to infer the causal relationship between exposure factors and disease risk. In recent years， MR has been widely used in studies on inference of the etiology of NAFLD. This article systematically summarizes the advances in the application of MR in NAFLD research， so as to provide new ideas for understanding the nature of the disease and scientific interventions.
