ABSTRACT

The differences of the active ingredients in Dendrobium huoshanense of different growth years and their protective effects on acute liver injury were studied to provide evidence for optimizing harvest time. The contents of polysaccharides, total flavonoids and total alkaloids in D. huoshanense of different growth years were determined by UV spectrophotometry, and the contents of gigantol in D. huoshanense were determined by HPLC. C57 BL/6 mice were randomly divided into blank control group(saline), modeling group(saline), high-dose(7.5 g·kg~(-1)) and low-dose(1.25 g·kg~(-1)) groups of D. huoshanense of different growth years. Each group was intragastrically administered every day for 2 weeks. 500 mg·kg~(-1) paracetamol was injected intraperitoneally 2 h after last treatment except the control group. After 12 hours, the serum and liver tissues were collected to detect the activities of ALT and AST, and the levels of SOD and MDA. The hepatic histopathological examination was performed. The results showed that the chemical constituents of D. huo-shanense of different growth years were significantly different(P<0.05). The contents of polysaccharide and gigantol of D. huoshanense of 2 growth years were the highest. The contents of flavonoids and alkaloids of D. huoshanense of 3 growth years were the hig-hest, followed by the D. huoshanense of 2 growth years, and the lowest were that of 1 growth year. Compared with the modeling group, D. huoshanense of different growth years could decrease the activities of ALT and AST in serum. Meanwhile, the levels of MDA reduced significantly, while those of SOD increased markedly. Histopathological results suggested that all D. huoshanense samples were effective in the reduction of the necrosis of hepatocytes in different degrees. The results of the multi-component SPSS paired tests showed that polysaccharide and gigantol probably played a leading role in the liver protection effects, while D. huoshanense of 2 growth years showed the best efficacy. The optimal harvesting time of D. huoshanense is 2 growth years.

ABSTRACT

OBJECTIVES@#The effect of Vps4b gene mutation on the expressions of cytokeratin 14 (CK14) and proliferating cell nuclear antigen (PCNA) in the Hertwig's epithelial root sheath (HERS) is investigated.@*METHODS@#The bilateral mandibular tissues of mouse on postnatal days 5, 9, 11, 15, and 19 were removed. The mandibular first molar tissue sections were obtained after paraffin embedding. The CK14 and PCNA expressions in the epithelial root sheath of the normal mouse and Vps4b knockout mouse were compared through immunohistochemistry.@*RESULTS@#On postnatal day 5, the normal mouse began to form HERS and had a strong positive PCNA expression in the HERS cells; on postnatal day 9, the HERS structure was continuous, and PCNA was positive in the HERS cells; on postnatal day 11, a small portion of HERS began to break, and PCNA was weakly positive in the HERS cells; on postnatal day 15, HERS continued to fracture; PCNA was weakly and positively expressed in the HERS cells on the root surface; on postnatal day 19, the tooth root reached normal physiological length, and PCNA was positively expressed in the HERS cells of the terminal part. Similar to the normal mouse, the gene knockout mouse also formed a HERS structure on postnatal day 5. However, HERS began to break on postnatal day 9. On postnatal day 19, only a few fragments of HERS were found on the root surface, and the root development was immature. Moreover, the expression intensity of PCNA in the gene knockout mouse was decreased.@*CONCLUSIONS@#The Vps4b gene mutation may change the CK14 and PCNA expressions, leading to abnormal root development.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

Objective:To analyze the cause of varicocele (VC) recurrence and investigate the efficacy of sub-inguinal microsurgical varicocelectomy (MV) for recurrent VC.Methods:All of 16 inpatients diagnosed as recurrent VC, in the Department of Andrology of the Affiliated Hospital of Qingdao University from 2015 April to 2019 April, were performed sub-inguinal MV. The age of the inpatients was 18-36 years old, median 27 years old.5 cases were originally performed retroperitoneal high ligation of spermatic vein and other 11 cases were originally performed laparoscopic varicocelectomy. During the review one to three years after the previous operation, all of 16 patients were diagnosed as VC recurrence. The complains of these patients during the review included male subfertility (10 cases) and scrotal pain (12 cases), in which 6 cases’ complains were male subfertility with scrotal pain. After admission, 13 patients were classified as Grade Ⅲ (left in 8 cases, bilateral in 5 cases) and 3 patients as Grade Ⅱ (all left). The median of their visual analogue scale (VAS) was 2.5. Color doppler flow imaging (CDFI) grading showed: Grade Ⅲ in 12 cases (left in 7 cases, bilateral in 5 cases), Grade Ⅱ in 4 cases (all left). Particularly, 12 of them were Graded as Ⅲ simultaneously accompanying with Nut-cracker Phenomenon (NCP). Preoperative tests showed that the average serum testosterone was (16.2±4.9)nmol/ml, the average sperm concentration was (11.8±3.9)×10 6/ml and the progressive motility rate (PR) was (24.4±4.2)%. All of the patients were performed sub-inguinal MV using general anesthesia and supine position. The spermatic cords were clearly exposed and padded up by inserting gauze strips under them. During the operation, the field was magnified 4-6 times with the microscope. Then all of the dilated external and internal spermatic veins were ligated, at the same time the internal spermatic artery and lymph vessels were well preserved. During these operations, 11 patients underwent left-side MV, while other 5 did bilateral MVs. During these MVs, we found twisted and dilated external and internal spermatic veins in all cases and well preserved the internal spermatic arteries and lymph vessels. The number of ligated left and right external spermatic veins were(2.1±0.6) and (1.4±0.5)respectively and the number of ligated left and right internal spermatic veins were (10.1±1.1) and (6.6±0.5) respectively. We also found out(1.3±0.5) internal spermatic arteries and (3.0±1.0)lymph-vessels on left side. On right side, there were (1.4±0.5) internal spermatic arteries and (2.6±0.5) lymph-vessels respectively. At last, we summarily analyzed the pre-operative and post-operative VAS, serum testosterone, CDFI and semen analysis data. Results:All of the 16 sub-inguinal MVs were successfully performed. All patients were reviewed comprehensively 6 months after MV. The reviewed results showed that the post-operative VAS was significantly reduced ( Z=-2.994, P<0.05), palpable scrotal vessels disappeared and Valsalva tests were negative. No obvious reflux of internal spermatic veins were detected by CDFI. Interestingly, the sperm concentration and motility were both significantly improved 6 months after MV ( P<0.05), while there was not remarkable increase of the serum testosterone after MV ( P>0.05). During the follow up, no testicular atrophy, hydrocele and other complications were found. Up to submission, five of the ten patients who presented for male subfertility have impregnated their wives. Conclusions:The most possible cause of VC recurrence could be the omission of the external and internal spermatic veins, particularly in the grade Ⅲ VC patients or VC accompanied with NCP. The sub-inguinal MV, which can discover more twisted spermatic veins and at the same time preserve the spermatic artery and lymph-vessels, shows better clinical efficacy than other procedures.

ABSTRACT

Objective:To explore the perivenous blocking management strategy for portal vein-superior mesenteric vein (PSMV) resection and reconstruction and its effect on postoperative complications in patients undergoing pancreaticoduodenectomy (PD).Methods:The data of 137 patients with pancreatic cancer treated with PD in Beijing Chaoyang Hospital Affiliated to Capital Medical University, Chaoyang Central Hospital, the Second Hospital of Chaoyang, Rizhao Central Hospital, the Second People's Hospital of Binzhou from January 2010 to December 2020 were collected. There were 83 males and 54 females with an average age of 61.8 years. There were 42 patients in the reconstruction group and 95 patients in the control group. The main intraoperative indexes and postoperative complications were compared between the two groups with the aim to review our experience in PSMV resection and reconstruction by using the perivenous blocking management strategy.Results:PD was successfully completed in 137 patients in the reconstruction group, the PSMV blocking time was 15-120 min, with a median of 30 min. The operation time 380 (330, 465) min, intraoperative blood loss 725 (500, 1000) ml, and postoperative hospital stay 21.0 (16.0, 28.0) d in the reconstruction group were significantly higher than those of control group [305 (280, 340) min, 400 (300, 500) ml and 18.0 (14.0, 24.5) d] (all P<0.05). The reoperation rate and perioperative mortality were 4.8% (2/42) and 2.4% (1/42) in the reconstruction group, while 2.1% (2/95) and 1.0% (1/95) in the control group, respectively. There was no significant difference between the two groups (both P>0.05). The incidence of pancreatic fistula, peritoneal effusion and infection, pulmonary infection of the reconstruction group was significantly higher than those of the control group ( P<0.05). There was no significant difference in the incidence of postoperative bleeding, delayed gastric emptying, biliary fistula, incision infection, reoperation between the two groups ( P>0.05). Conclusions:PSMV resection and reconstruction significantly increased the incidences of complication after PD, including pancreatic fistula, peritoneal effusion/infection and pulmonary infection. The perivenous blocking management strategy significantly promoted smooth postoperative recovery and effectively reduced morbidity rates of postoperative bleeding and mortality after PSMV resection and reconstruction in PD.

ABSTRACT

Liver is the most common metastatic organ in patients with advanced colorectal cancer. Once colorectal cancer liver metastasis (CRLM) occurs, the prognosis will be poor. Therefore early detection of CRLM has a great clinical significance for improving the prognosis of CRLM patients. Surgical resection of primary and metastatic lesion is the only possible curable option for CRLM, translational therapy, interventional therapy and multidisciplinary team also provide more treatment ideas. Long non-coding RNA, cancer stem cells and phosphatidylinositide-3-kinases/protein kinase B signaling pathway reveal the main mechanism of CRLM from different aspects. This article reviews the recent advances in the early diagnosis, treatments and main mechanisms of CRLM.

ABSTRACT

Objective:To investigate the effect of thrombus burden on the clinical outcome of endovascular recanalization in large vessel occlusive stroke.Methods:Patients with acute anterior circulation occlusion who underwent endovascular treatment within 24 hours after onset in Zhengzhou University People′s Hospital from January 2018 to December 2019 were retrospectively collected. According to the clot burden score (CBS) of DSA, total objectives were divided into CBS≥6 group (24 cases) and CBS<6 group (38 cases). Clinical data of the two groups were collected and the modified Rankin scale (mRS) was used to evaluate the clinical outcome at 90 days after surgery. Independent sample t-test, Wilcoxon rank sum test and χ 2 test were used to compare the clinical data between the two groups. Independent risk factors affecting the clinical outcome were analyzed by binary logistic regression. Results:There were no statistically significant differences in basic demographic data, stroke risk factors and other factors between the CBS≥6 group and CBS<6 group ( P>0.05).The proportion of using tirofiban after surgery in the CBS≥6 group (63.2%, 24/38) was lower than that in the CBS<6 group (87.5%, 21/24) (χ2=4.380, P=0.044). The discharge NIHSS score of the CBS≥6 group was [5.0 (3.3, 7.8) points] lower than CBS<6 group [8.5 (1.8, 14.5) points] ( Z=5.221, P=0.022). The proportion of postoperative mRS 0-2 was (91.7%, 22/24) in the CBS≥6 group higher than CBS<6 group(39.5%, 15/38) (χ2=20.486, P=0.001), there were no statistically significant differences between the two groups ( P<0.05). The results of binary logistics regression analysis showed the CBS groups (OR=0.042, 95%CI 0.007-0.244 , P=0.001) was an independent risk factor affecting good outcome. Subgroup analysis of whether tirofiban was used or not showed there was no statistically significant difference in clinical prognosis between the two groups ( P>0.05). Conclusions:The clinical outcome of CBS≥6 group is significantly better than that of CBS<6 group, and patients with small thrombus burden are more likely to get a good clinical outcome of 90 days.

ABSTRACT

Objective:To investigate the perfection and improvement of the execution of integrative medicine therapy in severe tetanus therapy, to successfully control tetanus severe spasms, autonomic dysfunction and prevent lethal side-effect of prolong and high-dosage sedative-muscle-relaxant therapy, resulted in significant reduction of mortality of tetanus.Methods:Symptoms, treatments and outcome of tetanus patients admitted to Peking University Third Hospital from 1965 to 2020 were reviewed. Patients were classified with Ablett classification. The cases of Ablett grade Ⅲ and Ⅳ were severe tetanus. The patients were divided into two groups according to whether they were treated together with traditional Chinese medicine (TCM) simultaneously during the standard tetanus treatment; the patients in the TCM group were divided into the tetanus TCM medication group and the non tetanus TCM medication group according to the medicine provided whether was in accord with the conventional tetanus TCM prescriptions. The mortality of each group was calculated. In addition, one survived and one deceased case with severe convulsion, autonomic nerve dysfunction (Ablett grade Ⅳ) were selected, combined with the treatment methods and curative effects, the types, use methods and outcomes of Chinese and Western medicine were analyzed.Results:The 46 tetanus cases were treated with Western medicine. Twenty-two of them, TCM were applied. Fifteen of the 22 cases took the TCM prescription which was accord with the conventional tetanus prescription. The mortality of the 46 cases was 21.7% (10/46). The number of non-TCM group was 24 cases, with mortality of 20.8% (5/24); 1 case was Ablett Ⅱ, 1 was Ablett Ⅲ and 3 were Ablett Ⅳ. The number of the TCM group was 22 cases, with mortality of 22.7% (5/22), 2 cases were Ablett Ⅲ, 3 were Ablett Ⅳ. The TCM prescription of these 5 deceased cases was not directed towards tetanus. The tetanus TCM medication group was 15 cases, with no mortality. Case analyses: case 1 was intubated because of severe spasms. Autonomic dysfunction occurred on the 8th day after admission. Esmolol with increasing the dosage of the sedatives and muscle relaxant, was not effective. Tetanus TCM was applied after 2 days of autonomic dysfunction happened. Autonomic dysfunction was then under controlled on the 2nd day post-TCM. She was recovery and discharged after 4 weeks. Case 2, also was intubated because of severe spasms. Autonomic dysfunction happened on the 3rd day after admission, and failed to be controlled by large-dose sedatives, muscle relaxant, and Esmolol. After 8 days of persistent autonomic dysfunction, tetanus TCM was applied and autonomic dysfunction was under controlled on the 2nd day post-TCM administration. Large dosage of muscle-relaxant was applied continuously. After 5 days' administration of TCM, the TCM was withdrew. One day after the withdrawal of TCM, respiratory and cardiac arrest happened because of the diffused bronchiole obstruction with pulmonary secretions loading.Conclusion:Based on the precise and real-time diagnosis of the state of the disease, integrative medicine therapy with an overall analysis tetanus TCM prescription, is the key of declining tetanus mortality.

ABSTRACT

Objective:To investigate the effects of celecoxib and anti-osteogenesis tablets on urinary biomarkers pyridinoline (PYD) and deoxypyridinoline (DPD) in adult patients with Kashin-Beck disease (KBD) in Qinghai Province, and to provide scientific basis for treatment of adult KBD.Methods:According to the "Diagnosis of Kaschin-Beck disease" (WS/T 207-2010), in July 2017, 120 cases of adult KBD that were selected from the KBD area in Qinghai Province were divided into non-drug treatment group ( n = 66) and drug treatment group ( n = 54), and 89 healthy adults were selected as control group. The drug treatment group was taken celecoxib and anti-osteogenesis tablets for 6 months. Morning urine samples were collected from the three groups. The contentss of PYD and DPD in urine were detected by enzyme linked immunosorbent assay (ELISA), and the test results were corrected with creatinine (Cre). Results:There were no statistically significant differences in gender ratio and age among non-drug treatment group, drug treatment group and control group (χ 2 = 0.820, F = 0.379, P > 0.05). The medians of urinary PYD in the three groups were 1 106.39, 812.18, 702.53 ng/μmol Cre, and the medians of DPD were 1 325.58, 802.54, 752.38 ng/μmol Cre, respectively. The differences were statistically significant among the three groups ( H = 13.849, 34.621, P < 0.01). The contents of PYD and DPD in drug treatment group were lower than those in non-drug treatment group ( P < 0.05). Conclusion:Celecoxib and anti-osteogenesis tablets can reduce the urinary levels of PYD and DPD in adult patients with KBD.

ABSTRACT

BACKGROUND: Percutaneous curved vertebroplasty is a new method for the treatment of osteoporotic vertebral compression fractures, which can achieve a good therapeutic effect, while the distribution of bone cement has not been explored thoroughly. OBJECTIVE: To retrospectively analyze the therapeutic effect of percutaneous curved vertebroplasty and the distribution characteristics of bone cement in the treatment of osteoporotic vertebral compression fractures. METHODS: A total of 28 patients with osteoporotic vertebral compression fractures of a single thoracic or lumbar vertebrate, who were admitted to Qingdao Municipal Hospital from June 2017 to February 2018, including 2 males and 26 females, aged 62-86 years old, underwent percutaneous curved vertebroplasty and were retrospectively reviewed. The bone cement was injected at the puncture side, the middle of the vertebrate and the contralateral side respectively. The change of anterior vertebral body height of the injured vertebrae and the leakage of bone cement postoperatively were observed according to X-ray images preoperatively, 48 hours and 6 months postoperatively. The bone cement distribution within the vertebrate was observed by CT scanning. Visual analogue scale score and Oswestry disability index were recorded for the evaluation of recovery. All protocols were approved by the Ethical Committee of Qingdao Municipal Hospital. RESULTS AND CONCLUSION: (1) There were 6 out of 28 cases of bone cement leakage, including 4 cases of paravertebral leakage and 2 cases of intervertebral space leakage, and no clinical symptoms were observed in all the 6 cases. CT scanning showed that the bone cement was mainly distributed in the anterior 2/3 of the vertebral body. The maximum distribution area of bone cement was (4.5±0.9) cm2, with the contralateral area (2.0±0.5) cm2 and the puncture side area (2.5±0.7) cm2, which makes the ratio of the puncture side area versus contralateral area 0.85±0.27. (2) The anterior vertebral body heights preoperatively showed no significant difference than those postoperatively in 28 patients (P > 0.05). (3) The visual analogue scale score and Oswestry disability index 48 hours and 6 months postoperatively were both significantly different from those before operation (P < 0.05). (4) The results showed that percutaneous curved vertebroplasty treatment of osteoporotic vertebral compression fractures has the advantages of accurate surgical effects and even distribution of bone cement.

ABSTRACT

OBJECTIVE@#To detect variant of the CD40L gene and infection of Jamestown Canyon virus (JCV) in a 7-year-and-9-month-old boy with co-commitment progressive multifocal leukoencephalopathy (PML) and X-linked hyper IgM syndrome (XHIGM).@*METHODS@#Peripheral blood samples of the child and his parents were collected for the extraction of genomic DNA. The 5 exons and exon/intronic boundaries of the CD40L gene were subjected to PCR amplification and sequencing. Suspected variants were analyzed by using bioinformatic software. The JCV gene was amplified from genomic DNA by nested PCR and sequenced.@*RESULTS@#The child was found to harbor a hemizygous c.506 A>C (p.Y169S) missense variant in exon 5 of the CD40L gene. The variant may affect the TNFH domain of the CD40L protein and result in structural instability and loss of hydrophobic interaction between CD40L and CD40. As predicted by PolyPhen2 and SIFT software, the variant was probably damaging (score = 1.00) and deleterious (score= -8.868). His mother was found to be a heterozygous carrier, while the same variant was not found in his father. Gel electrophoresis of the nested PCR product revealed presence of target JCV band, which was confirmed to be 99% identical with the JCV gene by sequencing.@*CONCLUSION@#The patient was diagnosed with co-commitment XHIGM and PML based on the testing of the CD40L gene and JCV infection.

ABSTRACT

Since the concept of "safe area" put forward by Lewinnek, it has been widely recognized. While in recent years, many scholars have found that even if the acetabular prosthesis was placed on the "safe area", there were still many unexplained dislocation after total hip arthroplasty. And scholars began to question whether the "safe area" is really suitable for all patients. Spinal degeneration, deformity, lumbar fusion, etc. will lead to spine sagittal imbalance and changes in pelvic activity, which could lead to changes in acetabular orientation, and ultimately lead to edge loading, wear, impact, and even dislocation after total hip replacement. From the perspective of wear, impact and dislocation, it is determined by the functional positioning of the acetabular cup, not the anatomical positioning. The anatomical positioning and functional positioning of the neutral pelvic acetabular cup in the standing position can be considered equivalent. For pelvic rotation more than 20°, functional placement needs to be considered. In recent years, as the understanding of the internal relationship between the spine-pelvis-hip joint has become more and more profound, some scholars further classify the hip-spine relationship according to whether the spine is stiff or deformed, and propose corresponding acetabulums according to different types of hip-spine relationships The function of placement, so as to achieve a stable artificial hip joint. Therefore, it is of great significance to fully assess whether the patient's sagittal plane is balanced before surgery to guide artificial hip replacement surgery.

ABSTRACT

Context: Owing to the increasing age of the population, the incidence of hepatocellular carcinoma (HCC) in the elderly is increasing annually. Aims: This study aims to investigate the clinical efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with low-dose apatinib for unresectable HCC treatment in elderly patients (≥65 years). Settings and Design: The clinical data from 61 elderly patients with unresectable HCC who were retrospectively analyzed. Subjects and Methods: Of these 61 patients, 27 received TACE combined with low-dose (250 mg/qd) apatinib (experimental group), and 34 patients received the standard TACE treatment (control group). The short-term efficacy was evaluated according to the mRECIST1.1 standards, and the mid- and long-term efficacy and safety in the two groups of patients were evaluated. Statistical Analysis Used: Statistical analyses were performed using the Statistical Package for the Social Sciences software (version 20.0; SPSS). Results: Both the objective response rate and disease control rate of the experimental group were significantly higher than those of control group (P < 0.05). The 6-month and 12-month survival rates of the experimental group were significantly higher than those of control group too (P < 0.05). The median survival in the experimental group was longer than in the control group (26.0 months vs. 20.0 months). The adverse reactions related to the intake of apatinib were higher in the experimental than the control group, but were generally alleviated after symptomatic treatment. Conclusions: TACE combined with low-dose apatinib provides an alternative treatment option for elderly patients with unresectable HCC. Our clinical study has proven its safety and efficacy.

ABSTRACT

Aims: The aim of this study is to investigate patients with unresectable Stage III non-small-cell lung cancer (NSCLC) receiving radiotherapy with induction and concurrent pemetrexed or docetaxel plus cisplatin (PP/DP) chemotherapy and to identify the subgroup most likely to benefit from induction chemotherapy (IC). Subjects and Methods: Patients with unresectable measurable Stage III NSCLC received two cycles of PP/DP IC followed by concurrent chemoradiotherapy at a dose of 60–66 Gy. Statistical Analysis Used: Cox regression analysis was performed to evaluate the prognostic factors for survival; logistic regression analysis was used to evaluate the predictors for response to IC, and the receiver operating characteristic curves were used to evaluate the independent factors predicting response. Results: Eighty patients were included; the median survival time (MST) was 22.1 months. Partial response (PR) to IC was an independent prognostic factor for overall survival. For patients in the PR and stable disease groups, the MST was 36.7 and 19.5 months, respectively. The independent predictors of PR to IC included classification as stage N3 cancer, baseline carcinoembryonic antigen (CEA) levels >10 ng/ml, and cytokeratin fragment 19 (CYFRA21-1) levels >6 ng/ml. With each additional independent predictor, the likelihood of having have PR to IC increased. Conclusions: Radiotherapy with induction and concurrent PP/DP chemotherapy is feasible for patients with unresectable Stage III NSCLC. IC may improve the survival of IC responders, as predicted by elevated CEA and CYFRA21-1 levels and classification as stage N3 cancer. Additional randomized trials on IC may consider these predictors to tailor individualized treatments

ABSTRACT

In ischemic stroke sequela phase, Rehmanniae Radix Praeparata-Corni Fructus drug pair has the effect in protecting damaged neurons, but its mechanism has not been clear. In this study, network pharmacology was used to predict the mechanism of Rehmanniae Radix Praeparata-Corni Fructus in the treatment of ischemic stroke sequela. Through database search and literature retrie-val, 40 active ingredients of Rehmanniae Radix Praeparata and Corni Fructus were obtained, and their targets were obtained through STITCH and TCMSP databases. The targets of ischemic stroke sequela were obtained through OMIM,GAD,TTD and DrugBank databases. By screening the intersections of active ingredients targets and stroke treatment targets, 21 potential targets were obtained. The DAVID database was used for GO enrichment analysis and KEGG pathway analysis of potential targets. GO enrichment analysis showed that Rehmanniae Radix Praeparata-Corni Fructus were mainly involved in regulation of blood pressure, negative regulation of extrinsic apoptotic signaling and positive regulation of angiogenesis. KEGG pathway analysis showed that Rehmanniae Radix Praeparata-Corni Fructus could inhibit inflammatory response and apoptosis signaling pathway by regulating HIF-VEGFA signaling pathway in neural stem cell proliferation, TNF signaling pathway and NF-kappaB signaling pathway. Molecular docking technique was used to verify that Rehmanniae Radix Praeparata-Corni Fructus component has a good binding activity with potential targets. The results showed that in ischemic stroke sequela phase, Rehmanniae Radix Praeparata-Corni Fructus drug pair could play an important role in recovering neural function, promoting the proliferation of neural stem cells, angiogenesis, preventing neural cells apoptosis and regulating inflammatory factors.

ABSTRACT

Objective@#To explore potential serum biomarkers of children with Kashin-Beck Disease (KBD) and the metabolic pathways to which the biomarkers belong.@*Methods@#A two-stage metabolomic study was employed. The discovery cohort included 56 patients, 51 internal controls, and 50 external controls. The metabolites were determined by HPLC-(Q-TOF)-MS and confirmed by Human Metabolome Databases (HMDB) and Metlin databases. MetaboAnalyst 3.0 and the Kyoto Encyclopedia of Genes and Genomes (KEGG) database were used to analyze the metabolic pathways of the candidate metabolites. The use of HPLC-(Q-TRAP)-MS enabled quantitative detection of the target metabolites which were chosen using the discovery study and verified in another independent verification cohort of 31 patients, 41 internal controls, and 50 external controls.@*Results@#Eight candidate metabolites were identified out in the discovery study, namely kynurenic acid, N-α-acetylarginine, 6-hydroxymelatonin, sphinganine, ceramide, sphingosine-1P, spermidine, and glycine. These metabolites exist in sphingolipid, glutathione, and tryptophan metabolic pathways. In the second-stage study, five candidate metabolites were validated, including kynurenic acid, N-α-acetylarginine, sphinganine, spermidine, and sphingosine-1P. Except for spermidine, all substances exhibited low expression in the case group compared with the external control group, and the difference in levels of sphinganine, spermidine, and sphingosine-1P was statistically significant.@*Conclusion@#The direction of change of levels of sphinganine, spermidine, and sphingosine-1P in the two-stage study cohorts was completely consistent, and the differences were statistically significant. Therefore, these substances can be used as potential biomarkers of KBD. Furthermore, these results raise the possibility that sphingolipid metabolic pathways may be closely related to KBD.

ABSTRACT

OBJECTIVE@#To observe the effect of hypnosis on pain and fear in the healthy acupuncture subjects.@*METHODS@#A total of 52 healthy subjects were randomized into an observation group and a control group, 26 cases in each one. In the observation group, the subjects received the first-time acupuncture under hypnosis. After wakened up and 30 min later, the subjects received the second-time acupuncture under clear consciousness condition. In the control group, the subjects received the first-time acupuncture under clear consciousness condition, 30 min later, received the second-time acupuncture under hypnosis. Likert scale was adopted to investigate the relaxation, pain sensation and the willingness in the subjects at the normal condition before acupuncture, after the first-time and the second-time acupuncture of the two groups separately. Using Boeran electronic blood pressure monitor, the pulse and blood pressure were measured in the subjects at the normal condition and after the first-time acupuncture of the two groups.@*RESULTS@#Compared with the normal condition, the relaxation degree was increased, the pain sensation decreased and the willingness enhanced after acupuncture either after hypnosis or after wakened-up in the observation group (0.05). In the control group, compared with the normal condition, after the first-time acupuncture (acupuncture in clear consciousness), the relaxation degree was decreased, pain was alleviated and the willingness was increased when acupuncture was exerted once again (0.05); compared with the first-time acupuncture, the relaxation degree was increased, pain alleviated and willingness enhanced after the second-time acupuncture (acupuncture after hypnosis) (0.05). In the control group, compared with the normal condition, the pulse was faster, both the diastolic pressure and systolic pressure were increased after the first-time acupuncture (<0.05, <0.01). In the observation group, compared with the normal condition, the pulse was getting slow and blood pressure was reduced after the first-time (acupuncture under hypnosis, <0.01). Compared with the first-time acupuncture in the control group, pulse was getting slow and blood pressure was reduced in the observation group after acupuncture under hypnosis (<0.001).@*CONCLUSION@#During acupuncture, with hypnosis combined, the fear alleviates, pain reduces and the willingness of acupuncture increases in the subjects.
