ABSTRACT

ObjectiveTo observe the effect of the Fangfeng Tongshengsan on post-chemoembolization syndrome with primary liver cancer or postoperative liver metastases of colorectal cancer. MethodSeventy-two patients suffered from post-chemoembolization syndrome after transcatheter hepatic arterial chemoembolization were randomly divided into 2 groups, including a Fangfeng Tongshengsan group and a control group, with 36 patients in each group. The patients in Fangfeng Tongshengsan group orally took the decoction for consecutive 7 d. The patients in the control group were physically cooled down with alcohol rub bath and ice pack for consecutive 7 d. Furthermore, the difference of fever, Karnofsky performance status (KPS), pain in the liver region, nausea vomiting, constipation, and liver function between these two groups were observed. ResultCompared with the control group, Fangfeng Tongshengsan significantly relieved fever, reduced the body temperature (P<0.05), and shortened the duration of fever (P<0.05), indicating that Fangfeng Tongshengsan remarkably improved the KPS (P<0.05). Meanwhile, Fangfeng Tongshengsan obviously alleviated nausea, vomiting, and constipation status and shortened the duration time compared with the control group (P<0.05). In addition, the parameters of liver function including alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), and total bilirubin (TBIL) were significantly decreased in the Fangfeng Tongshengsan group (P<0.05), which indicated that Fangfeng Tongshengsan alleviated liver dysfunction of patients with post-chemoembolization syndrome. ConclusionFangfeng Tongshengsan can be used to treat post-chemoembolization syndrome with primary liver cancer and postoperative liver metastases of colorectal cancer.

ABSTRACT

Objective: To establish and validate a nomogram-based predictive model for idiopathic hyperaldosteronism (IHA). Methods: This cross-sectional study was conducted with the collected clinical and biochemical data of patients with primary aldosteronism (PA) including 249 patients with unilateral primary aldosteronism (UPA) and 107 patients with IHA, who were treated at the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to November 2022. Plasma aldosterone concentration (PAC) and plasma renin concentration (PRC) were measured by chemiluminescence. Stepwise regression analysis was applied to select the key predictors of IHA, and a nomogram-based scoring model was developed. The model was validated in another external independent cohort of patients with PA including 62 patients with UPA and 43 patients with IHA, who were diagnosed at the Department of Endocrinology, First Affiliated Hospital of Zhengzhou University. An independent-sample t test, Mann-Whitney U test, and χ2 test were used for statistical analysis. Results: In the training cohort, in comparison with the UPA group, the IHA group showed a higher serum potassium level [M(Q1, Q3), 3.4 (3.1, 3.8) mmol/L vs. 2.7 (2.1, 3.1) mmol/L] and higher PRC [4.0 (2.1, 8.2) mU/L vs. 1.5 (0.6, 3.4) mU/L] and a lower PAC post-saline infusion test (SIT) [305 (222, 416) pmol/L vs. 720 (443, 1 136) pmol/L] and a lower rate of unilateral adrenal nodules [33.6% (36/107) vs. 81.1% (202/249)]; the intergroup differences in these measurements were statistically significant (all P<0.001). Serum potassium level, PRC, PAC post-SIT, and the rate of unilateral adrenal nodules showed similar performance in the IHA group in the validation cohort. After stepwise regression analysis for all significant variables in the training cohort, a scoring model based on a nomogram was constructed, and the predictive parameters included the rate of unilateral adrenal nodules, serum potassium concentration, PAC post-SIT, and PRC in the standing position. When the total score was ≥14, the model showed a sensitivity of 0.65 and specificity of 0.90 in the training cohort and a sensitivity of 0.56 and specificity of 1.00 in the validation cohort. Conclusion: The nomogram was used to successfully develop a model for prediction of IHA that could facilitate selection of patients with IHA who required medication directly.

ABSTRACT

OBJECTIVES@#To observe the clinical effect of wrist-ankle acupuncture on postpartum abdominal pain and its influence on serum beta-endorphin (β-EP) level in puerpera.@*METHODS@#Seventy patients with postpartum abdominal pain were randomly divided into an acupuncture + herbal medication group (35 cases, 1 case dropped out) and a herbal medication group (35 cases, 2 cases dropped out). In the herbal medication group, 1 day after delivery, modified shenghua decoction was taken orally, one dose a day. In the acupuncture + herbal medication group, on the basis of herbal medication, wrist-ankle acupuncture was given at the Lower 1 and Lower 2 of the ankles, once daily. The duration of treatment was 3 days in the two groups. Before and after treatment, the score of visual analogue scale (VAS) for pain, serum β-EP level, uterine fundus height, postpartum conditions of lochia and the uterine recovery at 42 days postpartum were compared in the patients of the two groups.@*RESULTS@#At each time point after treatment (24 h, 48 h and 72 h after delivery), VAS scores and the uterine fundus height were reduced as compared with those before treatment (2 h after delivery) in the two groups (P<0.05); these indexes in the acupuncture + herbal medication group were lower than those in the herbal medication group (P<0.05). After treatment (72 h after delivery), β-EP levels in the serum were increased when compared with those before treatment in the two groups (P<0.05), and the β-EP level in the acupuncture + herbal medication group was higher than that in the herbal medication group (P<0.05). The volume of postpartum lochia discharge in the acupuncture + herbal medication group was higher than that in the herbal medication group (P<0.05), while the duration of postpartum lochia discharge and the total time of lochia discharge were shorter (P<0.05). Regarding the recovery of the uterus at 42 days postpartum, there was no statistical significance between the two groups (P>0.05).@*CONCLUSIONS@#Wrist-ankle acupuncture obviously reduces the degree of postpartum abdominal pain and promotes the lochia discharge and the uterine recovery. The effect mechanism may be related to the up-regulation of serum β-EP level and the increase of pain threshold so that analgesia is obtained.

ABSTRACT

OBJECTIVES@#To investigate the clinical characteristics, pathology, and prognosis of children with diffuse endocapillary proliferative Henoch-Schönlein purpura nephritis (DEP-HSPN).@*METHODS@#A retrospective analysis was performed on the clinical, pathological, and prognosis data of 44 children with DEP-HSPN and 765 children without DEP-HSPN. The children with DEP-HSPN were diagnosed by renal biopsy in Jiangxi Provincial Children's Hospital from January 2006 to December 2021.@*RESULTS@#Among the 809 children with purpura nephritis, 44 (5.4%) had DEP-HSPN, with a mean age of (8±3) years, and there were 29 boys (65.9%) and 15 girls (34.1%). Compared with the non-DEP-HSPN group, the DEP-HSPN group had a significantly shorter time from onset to renal biopsy and a significantly higher proportion of children with respiratory infection or gross hematuria, and most children had nephrotic syndrome. The DEP-HSPN group had significantly higher levels of 24-hour urinary protein, urinary protein grading, microscopic hematuria grading, serum creatinine, and blood urea nitrogen and significantly lower levels of serum albumin and complement C3 (P<0.05). The DEP-HSPN group had a higher pathological grading, with predominant deposition of IgA in the mesangial area and capillary loops, and higher activity scores in the modified semi-quantitative scoring system (P<0.05). The Kaplan-Meier survival analysis showed that there was no significant difference in the renal complete remission rate between the two groups (P>0.05).@*CONCLUSIONS@#Children with DEP-HSPN have a rapid onset, severe clinical manifestations and pathological grading, and high activity scores in the modified semi-quantitative scoring system. However, most of the children with DEP-HSPN have a good prognosis, with a comparable renal complete remission rate to the children without DEP-HSPN.

ABSTRACT

Objective To validate the accuracy and reliability of structured-light three-dimensional (SL-3D) scanning in measuring the length and area of the regular and irregular scars on body surface and discuss its value in forensic practice. Methods The lengths of 30 cases of simulated linear scars and 50 cases of linear scars after injury were measured using soft ruler, vernier caliper + thin line method, and SL-3D scanning. The areas of 35 cases of simulated patchy scars and 15 cases of patchy scars after injury were measured using length × width, film tracing with coordinate paper method, pixel method, and SL-3D scanning, and then statistically analyzed. Results The differences between the length of the simulated linear scars measured by SL-3D scanning and standard length had no statistical significance. When simulated patchy scars and patchy scars after injury were measured with high surface curvature and large irregular areas, the differences between the results of SL-3D scanning measurement and the standard area had no statistical significance. When the length of 50 cases of linear scars after injury were measured using SL-3D scanning, the correlation coefficient between the measurement results of two different investigators was 0.998, and the correlation coefficient between the two measurement results by the same investigator was 1.000. The correlation coefficient between the results of SL-3D scanning and that of vernier caliper + thin line method was 0.996. Conclusion The three-dimensional information of the scars on the body surface can be acquired using SL-3D scanning. The measurement of the length and area of the scars is not influenced by the location of scars, curvature of surface, and human factors. The measurement results are accurate, reliable and has unique advantages.

ABSTRACT

Objective To investigate the intravenous lipid emulsion of vinorelbine, stability of the emulsion and factors influencing the stability. Methods The vinorelbine intravenous lipid emulsion injection was prepared by the processing process including the colostrum preparation, high pressure homogenization, filling and sealing, and rotary hot pressing sterilization. The effect of different temperatures on the stability of the emulsion was investigated by the orthogonal design using the emulsion particle size, pH and drug content as indicators. Results The three batches of pilot products were characterized by the emulsion particles with the average particle size <300 nm, uniform particle size distribution and no more than 1μm particles, as detected by the dynamic light scattering method. The emulsion showed an excellent stability at 5℃ within 6 months, but a gradual increase of the temperature significantly affected the stability of the emulsion, which caused the increase of particle size and decrease of pH. Conclusion The key parameters, processing conditions and engineering supports from the present study might be helpful for the industrial production of the drug-containing lipid nanoemulsion of vinorelbine for intravenous injection.

ABSTRACT

Professor YU Ren-cun believes that the responsibility of cough and asthma of lung cancer patients not only lies in the lungs, but also relates with spleen, kidney, heart and liver. Treatment should focus on the whole body and overall conditioning. Syndrome can be divided into 4 types: qi deficiency with phlegm resistance, yin deficiency with toxic heat, qi stagnation with blood stasis, and lung and kidney deficiency. Clinical treatment should pay attention to the combination of disease and syndrome, which can achieve satisfactory efficacy.

ABSTRACT

Objective Heart transplantation is an effective treatment of end-stage heart diseases and extending the time of donor heart preservation helps to make up for the shortage of donor hearts. This study was to investigate whether high-pressured mixed gas ( HPMG) of carbon monoxide and oxygen could prolong the time of donor heart preservation and its mechanisms. Methods Forty-eight C57BL/6 male mice aged 4-6 weeks were randomly divided in-to four groups of equal number:control ( the donor heart isolated but not transplanted) , immediate transplantation ( the donor heart transplanted right after isolated) , HTK-preservation ( the donor heart preserved in histidine-tryptophan-ketoglutarate solution for 24 hours after isolated, and HPMG preservation ( the donor heart preserved in an HPMG chamber with the oxygen partial pressure of 3200 hPa and carbon monoxide partial pressure of 800 hPa for 24 hours after isolated) .Another 36 recipient mice aged 6-8 weeks were randomly assigned to receive the donor heart immediately after harvested (n=12), preserved in HTK solution (n=12), or preserved in HPMG (n=12).At 2 hours after transplantation, the status of heart re-beating and cardiac function were compared among different groups of recipient mice.At 24 hours, tissues were taken from the transplanted hearts for examination of pathologic changes by HE stai-ning, detection of the apoptosis of cardiac cells by TUNEL, and determination of the expressions of microtubule-associated protein 1 light chain 3 -Ⅱ(LC3-Ⅱ) and B cell lymphoma/leukemia-2 (Bcl-2) by Western blot. Resul ts The re-beating rates of the imme-diately transplanted and HPMG-preserved hearts were significantly higher than that of the HTK-preserved ones (P<0.05).At 2 hours after transplantation, the cardiac function scores were 2.5 (2.0-2.9), 0.8 (0.5-1.0), and 4.5 (4.0-4.5) in the immediate implantation, HPMG-preservation and HTK-preservation groups respectively, with statistically significant differences between any two groups (P<0.05).The expressions of LC3-Ⅱand Bcl-2 were 2.06 ±0.29 and 0.87 ±0.18 in the HPMG-preserved heart recipients and 1.24 ±0.20 and 2.07 ±0.32 in the immediately transplanted heart recipients, both higher than 0.13 ±0.03 and 0.19 ±0.02 in the controls and 0.16 ±0.06 and 0.26 ±0.08 in the HTK-preserved heart recipients (P<0.05), the Bcl-2 higher in the HTK-pre-served heart recipients than in the controls (P<0.05), and the LC3-Ⅱ expression higher in the HPMG-preserved heart recipients than in the immediately transplanted heart recipients (P<0.05).HE staining showed that cell edema and inflammatory cell infiltration were more obvious in the HPMG-preserved heart recipients than in the controls and immediately transplanted heart recipients but less obvious than in the HTK-preserved heart recipients.The rate of cell apoptosis was dramatically increased in the HPMG-and HTK-pre-served heart recipients ([5.04 ±1.77]%and [26.72 ±5.23]%) in comparison with the controls ([1.08 ±0.56]%) (P<0.01) and immediately transplanted heart recipients ([2.13 ±1.71]%) (P<0.01) but decreased in the HPMG as compared with the HTK-preserved heart recipients (P<0.01). Conclusion High-pressured mixed gas preservation can reduce cold ischemia-reperfu-sion injury of the donor heart, which may be associated with its promotion of autophagy, provision of energy to cells, and apoptosis of cardiocytes in the donor heart.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of adenosine preconditioning on cell apoptosis and expressions of glucose-regulated protein (GRP-78) and cysteinyl aspartate-specific protease 12 (caspase-12) in rats with spinal cord ischemia-reperfusion injury.</p><p><b>METHODS</b>Twenty-seven rats were randomized into 3 equal groups and subjected to sham operation (group A), spinal cord ischemia-reperfusion injury (group B), or ischemia-reperfusion injury with adenosine treatment. Spinal cord ischemia-reperfusion injury was induced by cross-clamping of the abdominal aorta inferior to the left renal artery. The spinal cord function was assessed using the Modified Tarlov Scale at 6, 12, and 24 h after reperfusion. At 24 h after reperfusion, histological analysis was carried out with HE staining; cell apoptosis and viability were determined with TUNEL staining, and the expressions of GRP-78 and caspase-12 proteins were determined with Western blotting.</p><p><b>RESULTS</b>HE staining of the spinal cord showed extensive spinal cord injury such as cell edema in group B as compared with group C. Compared with group A, group B showed a significantly increased number of apoptotic cells; the number of apoptotic cells in group B was greater than that in group C. Compared with group B, group C showed significantly increased GRP-78 expression (P<0.01) and decreased caspase-12 expression (P<0.01).</p><p><b>CONCLUSION</b>Adenosine can up-regulate GRP-78 expression and down-regulate caspase-12 expression, and protects the spinal cord against ischemia-reperfusion injury by inhibiting cell apoptosis.</p>
