Label-free target discovery technology of small molecule drug and its application in traditional Chinese medicines / 药学学报

The discovery of drug targets plays a crucial role in drug research. Accurate information of small molecule drug-protein interaction can be provided by label-free target discovery technology without any structural modification at the small molecule. So, the label-free drug target discovery technology had become the powerful tool to discover the targets of drugs. Due to the “multi-component and multi-target” characteristics of traditional Chinese medicines (TCMs), the research on its targets and mechanism had been restricted. Based on potential of the label-free target discovery technology in the research of TCMs, this paper summarized the label-free target discovery technology and its application in TCMs research. It will provide a reference for the discovery of targets of TCMs and a new view for promoting the modernization of TCMs.

Clinical effects of island posterior femoral composite tissue flaps in the repair of sinus cavity pressure ulcers in the areas of ischial tuberosity and greater trochanter / 中华烧伤杂志

Objective: To explore the clinical effects of island posterior femoral composite tissue flaps in the repair of sinus cavity pressure ulcers in the areas of ischial tuberosity and greater trochanter. Methods: The retrospective observational study was conducted. From December 2018 to December 2021, 23 patients with sinus cavity pressure ulcers in the areas of ischial tuberosity and greater trochanter who met the inclusion criteria were admitted to Ganzhou People's Hospital, including 16 males and 7 females, aged 45 to 86 years. The size of pressure ulcers in ischial tuberosity ranged from 1.5 cm×1.0 cm to 8.0 cm×5.0 cm, and the size of pressure ulcers in greater trochanter ranged from 4.0 cm×3.0 cm to 20.0 cm×10.0 cm before debridement. After treatment of underlying diseases, debridement and vacuum sealing drainage for 5 to 14 days were performed. All the wounds were repaired by island posterior femoral composite tissue flaps, with area of 4.5 cm×3.0 cm-24.0 cm×12.0 cm, pedicle width of 3-5 cm, pedicle length of 5-8 cm, and rotation radius of 30-40 cm. Most of the donor site wounds were sutured directly, and only 4 donor site wounds were repaired by intermediate thickness skin graft from the contralateral thigh. The survival of composite tissue flaps, wound healing of the donor and recipient sites and the complications were observed. The recurrence of pressure ulcers, and the appearance and texture of flaps were observed during follow-up. Results: A total of 32 wounds in 23 patients were repaired by island posterior femoral composite tissue flaps (including 3 fascio subcutaneous flaps, 24 fascial flaps+fascio subcutaneous flaps, 2 fascial flaps+fascial dermal flaps, 2 fascial flaps+fascio subcutaneous flaps+femoral biceps flaps, and one fascial flap+fascio subcutaneous flap+gracilis muscle flap). Among them, 31 composite tissue flaps survived well, and a small portion of necrosis occurred in one fascial flap+fascio subcutaneous flap post surgery. The survival rate of composite tissue flap post surgery was 96.9% (31/32). Twenty-nine wounds in the recipient sites were healed, and 2 wounds were torn at the flap pedicle due to improper postural changes, and healed one week after bedside debridement. One wound was partially necrotic due to the flap bruising, and healed 10 days after re-debridement. Thirty-one wounds in the donor sites (including 4 skin graft areas) were healed, and one wound in the donor site was torn due to improper handling at discharge, and healed 15 days after re-debridement and suture. The complication rate was 12.5% (4/32), mainly the incision dehiscence of the flap pedicle and the donor sites (3 wounds), followed by venous congestion at the distal end of flap (one wound). During the follow-up of 3 to 24 months, the pressure ulcers did not recur and the flaps had good appearance and soft texture. Conclusions: The island posterior femoral composite tissue flaps has good blood circulation, large rotation radius, and sufficient tissue volume. It has a high survival rate, good wound healing, low skin grafting rate in the donor site, few postoperative complications, and good long-term effect in the repair of sinus cavity pressure ulcers in the areas of ischial tuberosity and greater trochanter.

RRM2 promotes tumor progression by interfering with G2/M cycle of prostate cancer cells / 现代泌尿外科杂志

【Objective】 To investigate the role of RRM2 in prostate cancer and the mechanism. 【Methods】 The data of prostate cancer expression profile were downloaded from The Cancer Genome Atlas (TCGA). The correlation between RRM2 expression and clinicopathological features and prognosis of prostate cancer was analyzed. The protein expressions of RRM2 in 55 cases of prostate cancer and 38 benign tissues were determined with immunohistochemistry (IHC). The effects of RRM2 on the biological process of prostate cancer were assessed with bioinformatic analysis. The biological process of RRM2 affecting the progression of prostate cancer was verified with Western blot and flow cytometry. 【Results】 RRM2 was highly expressed in prostate cancer, and the expression was positively correlated with the clinical stage, pathological grade and metastasis of prostate cancer (P<0.05). Higher RRM2 expression predicted poorer survival. RRM2 co-expression positively correlated genes were involved in cell cycle pathways, pyrimidine nucleotide metabolism, and biological processes such as RNA transport. Cell cycle pathways were significantly enriched. RRM2 was highly correlated with CDK1 and PCNA molecules. RRM2 knockdown reduced the protein expressions of CDK1 and PCNA in DU145 and LNCap cell lines, which were arrested in the G2/M phase. 【Conclusion】 RRM2 promotes tumor progression by interfering with G2/M cycle of prostate cancer cells.

Primary study of heat stress inducing early expression and secretion of tissue factor in vascular endothelial cells / 解放军医学杂志

Objective To explore the pattern of early expression and secretion of tissue factor(TF)in vascular endothelial cells induced by heat stress.Methods Thirty SPF-rated C57BL/6 male mice were randomly divided into five groups:the control group and groups of indicated recovery time,including 0,3,6,and 9 h in room temperature after heat stress(n=6).Mice in the heat stress groups were exposed to an animal incubator to reach 42.5℃for core body temperature for heat stroke.We analyzed the histopathological changes in the liver,lung,and kidney tissues with HE staining.We measured the TF mRNA in mice tissues by RT-qPCR and the plasma concentration of TF in mice with a commercial ELISA kit.Human umbilical vein endothelial cells(HUVECs)were placed in a culture incubator to build an in vitro heat stress model.HUVECs were divided into five groups,including a control group and groups of indicated recovery time,including 0,3,6,and 9 h after heat stress.We quantified the expression of TF mRNA and protein in HUVEC cells by RT-qPCR,Western blotting,and immunofluorescence and measured the secreted TF with a commercial ELISA kit.Results No significant pathological injury was observed in the tissues of the control group.Mice treated with heat stress had various degrees of structural injuries and hemorrhagic and inflammatory changes in multiple tissues.Compared to control group,the expression of TF mRNA significantly increased in the kidney of heat stress-treated mice with 0 and 3 h recovery time(1.719±0.018,1.241±0.178 vs.1.000±0.063),the lung with 3 h recovery time(2.444±0.511 vs.1.000±0.106)and the liver with 6 h recovery time(7.312±0.618 vs.1.000±0.147)(P<0.05).The concentration of TF in plasma also sustainedly elevated in mice with 0,3,6,and 9 h recovery time after heat stress as compared to control group[(132.426±17.920)pg/ml,(119.400±10.267)pg/ml,(107.374±13.495)pg/ml,(163.767±22.810)pg/ml vs.(75.479±13.831)pg/ml,respectively,P<0.01].The expression levels of TF mRNA were higher in heat stress HUVECs with 6 h and 9 h recovery time than the control cells(1.905±0.354,2.564±0.297 vs.1.000±0.097,P<0.01).Secreted TF in the supernatant from HUVECs treated with heat stress and different recovery time also increased significantly[(36.309±4.101)pg/ml,(38.425±5.484)pg/ml,(41.655±4.380)pg/ml,(43.586±4.718)pg/ml vs.(14.996±0.254)pg/ml,P<0.01].Conclusion Heat stress increased early expression and secretion of TF in vascular endothelial cells.Vascular endothelial cells may be a main source of circulating TF in heat stroke.

The effect and mechanism of exosomes from umbilical cord mesenchymal stem cells on pulmonary inflammation in chronic obstructive pulmonary disease rats / 天津医药

Objective To investigate the effect and mechanism of human umbilical cord mesenchymal stem cell exosomes(Exo)on pulmonary inflammation in chronic obstructive pulmonary disease(COPD)rats.Methods A total of 18 male SD rats were randomly divided into the control group,the COPD group and the COPD + Exo group with 6 rats in each group.COPD rat model was estalished by giving cigarette smoke and lipopolysaccharide(LPS)inhalation in the COPD group and the COPD + Exo group.Rats in the COPD + Exo group were injected with 100 μL of human umbilical mesenchymal stem cell exosome diluent(containing 2×107 exosomes)via tail vein.The control group and the COPD group were given equal amounts of phosphate buffered solution.One week after intervention,rats were killed and the peripheral blood,alveolar lavage fluid(BALF)and lung tissue samples were collected.The histopathological changes in lung tissue of each group were observed using Hematoxylin and Eosin(HE)staining.The number of inflammatory cells in peripheral blood was counted by fully automated hematology analyzer.The serum levels of IL-1β,IL-6 and TNF-α were detected by enzyme-linked immunosorbent assay(ELISA).The expression levels of IL-1β,IL-6 and TNF-α mRNA in lung tissue were detected by qRT-PCR.Western blot assay was used to detect the protein expression levels of TLR4,p-NF-κB p65 and IκBα in lung tissue.Results In the control group,the structure of pulmonary alveolus was intact and regular,while in the COPD group,the structure of alveolus was disordered,some alveolus expanded irregularly,fused into bullae and even ruptured.The alveolar septa were widened and filled with a large number of inflammatory cells.Compared with the COPD group,the COPD+ Exo group had more intact alveolar structure and less infiltration of inflammatory cells in the alveolar septum.The inflammatory cells in peripheral blood decreased.The expression levels of IL-1β,IL-6 and TNF-α in serum and lung tissue were decreased(P<0.05).The expression of TLR4 and IκBα protein in lung tissue were increased,while the expression of p-NF-κb p65 protein decreased(P<0.05).Conclusion Human umbilical cord mesenchymal stem cell exosomes can alleviate pulmonary inflammation in COPD rats by modulating TLR4/NF-κB signaling pathway,thereby playing a lung-protective effect.

Risk factors of recurrence after transperineal anastomotic urethroplasty of post-traumatic urethral stricture patients and construction of a nomogram: a retrospective study / 中华泌尿外科杂志

Objective:To explore the risk factors for urethral stricture after transperineal anastomotic urethroplasty (TAU) by retrospectively analyzing patient data and to develop a nomogram to predict the risk of recurrence before the surgery.Methods:Clinical data of patients who underwent TAU because of post-traumatic urethral stricture from January 2016 to December 2017 in West China Hospital, Sichuan University were reviewd. A total of 78 patients were included in the retrospective analysis, with 13 of them having recurrence. The patients in the recurrence group had a median age of 49.8 and 76.9% (10/13) of them had membranous urethral stricture. The proximal urethra end was located above the superior margin of the pubic ramus (higher stricture site) in 53.8%(7/13)of patients in the recurrence group and the length of the stricture measured in the operation was (2.19±0.22) cm. In the non-recurrence group, the median age was (44.8±13.6) years old, 58.5% (38/65) of them had membranous urethral stricture, 21.5% (14/65) had higher stricture site, and the length of the stricture was (2.03±0.11) cm. Both univariate and multivariate logistics analyses were performed to evaluate the risk factors of recurrence of urethral stricture 5 years after surgery. The nomogram was built based on the multivariate logistics analysis. The Concordance Index (C-index), Receiver Operating Characteristic(ROC) curve and Calibration curve were used to evaluate the nomogram.Results:Univariate logistics analysis showed that higher stricture site, history of urethral dilation, smoking, diabetes and total serum protein may be associated with recurrence after surgery. Multivariate logistics analysis further confirmed that higher stricture site ( OR=34.64, 95% CI 3.71-754.53), history of urethral dilation( OR=13.15, 95% CI 1.27-210.00), smoking ( OR=13.75, 95% CI 2.15-166.05) and diabetes ( OR=64.98, 95% CI 3.80-1957.60) were independent risk factors for recurrent urethral stricture while higher total serum protein before surgery was related to lower recurrence risk ( OR=0.78, 95% CI 0.62-0.93). A nomogram was built based on the results. The C-index of the nomogram was 0.923(95% CI 0.908-0.938), the area under curve (AUC) was 0.923 (95% CI 0.855-0.991), and the Brier Score was 0.079. Conclusion:Higher stricture site, history of urethral dilation before surgery, smoking, diabetes and lower total serum protein before surgery are associated with higher recurrence TAU of post-traumatic urethral stricture patients. With the nomogram developed, prediction of the risk of recurrence could be achieved prior surgery.

Influencing factors of metabolic syndrome in community patients with schizophrenia / 四川精神卫生

BackgroundPatients with schizophrenia are at high risk of suffering from metabolic syndrome. Most previous studies on the influencing factors of metabolic syndrome focused on the inpatients and limited ones on patients dwelling in community. ObjectiveTo explore the influencing factors at different risk levels of metabolic syndrome in community-dwelling patients with schizophrenia in Guangzhou， so as to provide references for future interventions on metabolic syndrome in this patient population. MethodsIn November 2021， 3 339 patients with schizophrenia who were registered in and administered by Guangzhou Mental Health Information System were included. All these patients had finished the physical examination in 2020， and whether they had metabolic syndrome was assessed basing on Guideline for the prevention and treatment of type 2 diabetes mellitus in China （2020 edition）. Patients were divided into high-risk group （n=423）， critical group （n=1 524） and metabolic syndrome group （n=1 392） according to the Chinese expert consensus on the management of metabolic syndrome in patients with schizophrenia. Multiple logistic regression analysis were performed on the risk factors of metabolic syndrome in community-dwelling patients with schizophrenia. ResultsThe prevalence rate of metabolic syndrome in community-dwelling patients with schizophrenia was 41.69%. Univariate analysis showed that the results in gender （χ2=44.610）， age （χ2=55.992）， marriage status （χ2=30.755）， illness course （χ2=25.913） and body mass index （χ2=829.265） were significantly different among the three groups （P<0.01）. Kruskal-Wallis H test showed that the levels of waist circumference （H=920.331）， systolic blood pressure （H=436.673）， diastolic blood pressure （H=393.337）， fasting blood glucose （H=807.304）， triglyceride （H=1 134.125） and high-density lipoprotein cholesterol （H=593.615） among the three groups were significantly different （P<0.01）. Logistic regression analysis showed that age ≥50 （OR=1.761， 95% CI： 1.087~2.853）， overweight （OR=2.418， 95% CI： 1.862~3.140） and obesity （OR=57.903， 95% CI： 14.340~233.802） were risk factors contributing to high-risk patients becoming critical population （P<0.05 or 0.01）. Female gender （OR=1.295， 95% CI： 1.034~1.622）， aged 40~49 （OR=2.597， 95% CI： 1.582~4.263）， age ≥50 （OR=4.392， 95% CI： 2.609~7.395）， overweight （OR=7.844， 95% CI： 6.018~10.223） and obesity （OR=426.785， 95% CI： 105.724~1 722.839） were risk factors for high-risk patients developing into metabolic syndrome population （P<0.05 or 0.01）. ConclusionThe prevalence rate of metabolic syndrome is higher in community-dwelling patients with schizophrenia. Female gender， older age， overweight and obesity would increase the risk of metabolic syndrome in schizophrenic patients. ［Funded by Health Science and Technology Project in Guangzhou （number， 20221A010028）］

Intestinal Cckbr-specific knockout mouse as a novel model of salt-sensitive hypertension via sodium over-absorption / 老年心脏病学杂志（英文版）

OBJECTIVES@#To investigate the value of CCKBRfl/fl villin-Cre mice as a mouse model of salt-sensitive hypertension (SSH).@*METHODS@#In the first part, 2-month-old CCKBRfl/fl villin-Cre mice (CKO) and control CCKBRfl/fl mice (WT) were fed with normal diet (0.4% NaCl) or high salt diet (4% NaCl), separately for 6 weeks. In the rescue study, one week of hydrochlorothiazide or saline injection were treated with the CKO mice fed high salt diet. The blood pressure, biochemical indexes, and the expression of small intestinal sodium transporters (NHE3, NKCC1, eNaC) was detected. The organ injury markers (MMP2/MMP9) and the histopathological changes of kidneys were observed, whereas the changes of duodenal sodium absorption were detected by small intestinal perfusion in vivo.@*RESULTS@#The CCKBRfl/fl villin-Cre mice with high salt intake exhibited high blood pressure, increased duodenal sodium absorption and urinary sodium excretion, and with renal injury. The protein expression of NHE3, NKCC1 and eNaC were also significant increase in the intestine of CKO-HS mice. Treatment with hydrochlorothiazide remarkably attenuated the elevated blood pressure by high salt absorption in the CCKBRfl/fl villin-Cre mice, but no significant histopathological changes were observed.@*CONCLUSIONS@#These results support a crucial role of intestinal Cckbr deficiency on SSH development and the diuretic antihypertension effect in CCKBRfl/fl villin-Cre mice.

@#AIM: To compare the clinical efficacy and safety of gatifloxacin eye drops and levofloxacin eye drops in the treatment of acute bacterial conjunctivitis using Meta-analysis.<p>METHODS: According to the Cochrane systematic evaluation method, “gatifloxacin” “levofloxacin” and “acute bacterial conjunctivitis” were used as keywords for literature search in Embase, Cochrane library, Pubmed, Medline, CNKI, Wanfang, VIP and CBMdisc from the establishment of the database to March 1, 2021. Randomized controlled trials(RCTs)gatifloxacin eye drops and levofloxacin eye drops in the treatment of acute bacterial conjunctivitis were included. Cochrane bias risk assessment tool was used to evaluate the quality of the included studies. RevMan5.3 software was used for combined analysis. Egger's test in Stata12 was used to assess publication bias, and the level of evidence was evaluated according to the GRADE system.<p>RESULTS: A total of 10 RCTs were included in this study with 1 149 patients. The control group was treated with levofloxacin and the experimental group was treated with gatifloxacin. The results of Meta-analysis showed that the clinical effective rate of acute bacterial conjunctivitis in gatifloxacin group was higher than that in levofloxacin group(<i>OR</i>=3.75, 95%<i>CI</i>: 2.52-5.58, <i>P</i><0.00001). Egger's test suggested there was publication bias among studies. And GRADE rating results indicated, the level of evidence was VERY LOW. The incidence of adverse drug reactions in the gatifloxacin group was lower than that in levofloxacin group(<i>OR</i>=0.37, 95%<i>CI</i>: 0.19-0.71, <i>P</i>=0.003). No publication bias was observed in Egger's test and GRADE showed the level of evidence was LOW.<p>CONCLUSION: Gatifloxacin eye drops is more effective than levofloxacin eye drops in the treatment of acute bacterial conjunctivitis, and has lower adverse effect rates. And due to the low levels of evidence included, more multicenter, randomized double-blind clinical trials are needed to improve the strength of evidence for the clinical efficacy of gatifloxacin eye drops in the treatment of acute bacterial conjunctivitis.

Semimonthly Table of Contents Nationwide investigation and problems analysis of pharmaceutical preparations in medical institutions / 中国药房

@#OBJECTIVE To investigate the situation of pharmaceutical pr eparations in medical institutions （hereinafter refer to hospital preparations ），and to promote the sustained and healthy development of hospital preparations. METHODS Under the organization of National Pharmacy Administration & Quality Control Center ，internet survey was adopted to statistically analyze the data of hospital preparations in 2019 that was completed and reported by the secondary general hospitals and above in provinces （cities，districts）and Xinjiang Production and Construction Corps. RESULTS Among the 4 639 hospitals，9.36％ had drug approval numbers and 8.15％ had preparation laboratories. The average ratio of the number of hospital preparations in production to the number of preparations approved was 0.72，and that of 41.52％ hospital was concentrated in 1-0.9. Self-produced by hospital was the main production mode of hospital preparations ；the higher hospital level was ，the higher the proportion of self-production combined with commissioned processing ，while the lower the proportion of commissioned processing only. In hospitals with preparation approval numbers ，the proportion of owning TCM preparations was the highest （73.66％），followed by common chemical preparations （69.93％）. From perspective of annual output value of hospital preparations ，tertiary hospitals were higher than secondary hospitals ，and private hospitals were higher than public hospitals ；it was related to the production mode ，varieties of hospital preparations and the establishment of the preparation laboratories. There was a trend that the development of hospital preparations in C entral China ，North China and South China was better than that in the Northeast China ，Northwest China and Southwest China. CONCLUSIONS At present ，hospital preparations in China are mainly made in medical institutions ， com and the types are relatively limited. The regional developmentis unbalanced and the scale of hospital preparations is reduced.It is suggested that medical institutions should pay attention to the innovation of hospital preparations ，especially to deve lopment of characteristic preparations with definite curative effect ，so as to give full play to their role of “shortage make-up ”. Great importance also should be paid to the policy support of dispensing and the establishment of regional dispensing centers.

Primary lung adenocarcinoma complicated with lung hamartoma: A case report and literature review / 中南大学学报(医学版)

The clinical data for a patient with primary lung adenocarcinoma complicated with pulmonary hamartoma, who admitted to Zunyi Medical University Hospital in September 2020, was retrospectively analyzed. The 62-years-old male visited outpatient service because of dysphagia in March 2015, and the pulmonary nodules were found. In September 2020, the computed tomography indicated the enlarged nodule in the lower lobe of left lung with lobulation, and there was ground glass nodule in the upper lobe of left lung. After thoracoscopic wedge surgery, the primary pulmonary adenocarcinoma in the upper lobe of left lung and pulmonary hamartoma in the lower lobe of left lung were confirmed by pathology. Whole exon sequencing revealed that kinesin family member 20B (KIF20B) gene was not expressed in lung adenocarcinoma, but was expressed in pulmonary hamartoma. The clinical manifestations of lung adenocarcinoma complicated with pulmonary hamartoma was not typical, which could locate in the same side and different sides of the lung. The imaging manifestations of the 2 kinds of tumors were diverse and can not be completely distinguished. The pathological examination after surgery is the gold standard, and the possibility of malignant transformation of pulmonary hamartoma should be warned.

Clinical characteristics of rare adrenal angiomyolipoma / 中华泌尿外科杂志

Objective:To analyze the clinical characteristics of rare adrenal angiomyolipoma.Methods:Clinical data of 5 patients with adrenal angiomyolipoma admitted to West China Hospital of Sichuan University from April 2009 to April 2019 were retrospectively analyzed. There were 2 males and 3 females. Age ranged from 40 to 57 years old, with an average of 46.7(40-57) years old. Clinical manifestations included right upper abdominal mass in 1 case, pain in the lower back in 1 case, and no significant symptoms were found in the rest. One patient was complicated with hypertension, one patient was complicated with decreased activities of epinephrine, norepinephrine and renin activity (orthosis), and the other patients had no abnormal hormones. 2 patients underwent abdominal ultrasound with " strong echo mass in adrenal area" , and all underwent enhanced abdominal CT with " space occupying lesion in adrenal area" , which was specifically manifested as tumors with mixed density in fat, blood vessels, muscle and so on. The average tumor diameter was 5.8(2.3-9.1) cm, including 2 cases on the left, 3 cases on the right, and 1 case with renal angiomyolipoma. All patients underwent laparoscopic adrenal tumor resection.Results:All the 5 patients underwent surgical resection successfully and were diagnosed as adrenal angiomyolipoma by pathological examination of tumor specimens after surgery. There was no significant change in blood pressure level of patients with hypertension after surgery. Follow-up time was 2-7 years and no recurrence.Conclusions:Adrenal angiomyolipoma is an extremely rare benign nonfunctional disease, which is more common in middle age. Most of the patients had no clinical history and signs. The tumor has no hormone secretion function and can be basically diagnosed with CT and other imaging examinations. The final diagnosis depends on pathological examination. After operation, the prognosis of adrenal angiomyolipoma is good.
