ABSTRACT

Objective:To observe the clinical efficacy of Sheti Zhiqiu decoction combined with intradermal needling in treatment of allergic rhinitis (AR) of deficient cold of lung Qi syndrome and its effect on cytokines of helper T cell 17 (Th17) and regulatory T cells (Treg). Method:A total of 105 patients with AR of deficient cold of lung Qi syndrome were randomly divided into traditional Chinese medicine (TCM) group, combination group and western medicine group, with 35 cases in each group. The TCM group was treated with Sheti Zhiqiu decoction, 1 dose a day. The combination group was treated with intradermal needling in addition to the therapy of the TCM group. The selected acupoints were Yintang, bilateral Yingxiang, Fengchi, Feishu and Zusanli. The needles were retained for 3 days before being replaced. The western medicine group was treated with mometasone furoate nasal spray, 100 μg/time at each side of the nasal cavity, <italic>qd</italic>, and desloratadine citrate tablet, 8.8 mg/time, <italic>qd</italic>. Three groups were treated for 4 weeks and followed up for 3 months. Nasal and ocular symptom scores and rhinoconjunctivitis quality of life questionnaire (RQLQ) scores of patients in three groups were observed before and after treatment. Levels of serum interleukin-17 (IL-17), interleukin-10 (IL-10) and transforming growth factor-<italic>β</italic><sub>1</sub> (TGF-<italic>β</italic><sub>1</sub>) were measured before and after treatment. The clinical efficacy and safety were evaluated, and the disease recurrence rate was observed during the follow-up period. Result:Compared with before treatment, nasal and ocular symptom scores and total score, and RQLQ scores and total score of patients in three groups were significantly decreased after treatment (<italic>P</italic><0.01). Compared with the TCM group and the western medicine group after treatment, except for eyes itching/foreign body sensation/red eyes score, nasal and ocular symptom scores and total score, and RQLQ scores and total score of the combination group were lower(<italic>P</italic><0.05,<italic>P</italic><0.01). Compared with before treatment, level of serum IL-17 of patients in three groups was significantly decreased (<italic>P</italic><0.01), while levels of IL-10 and TGF-<italic>β</italic><sub>1</sub> were significantly increased after treatment (<italic>P</italic><0.01). Compared with the TCM group and the western medicine group after treatment, level of serum IL-17 was lower, whereas levels of IL-10 and TGF-<italic>β</italic><sub>1</sub> were higher in the combination group (<italic>P</italic><0.05,<italic>P</italic><0.01). The clinical efficacy of the combination group was better than that of the TCM medicine group and the western medicine group (Z=-2.207,Z=-2.185,<italic>P</italic><0.05). There was no significant difference in recurrence rate between combination group and the TCM group, and the recurrence rate of both groups was lower than that of the western medicine group(<italic>χ</italic><sup>2</sup>=5.020,<italic>χ</italic><sup>2</sup>=4.835,<italic>P</italic><0.05). There was no significant adverse reaction during the treatment period in three groups. Conclusion:Sheti Zhiqiu decoction combined with intradermal needling is effective in treatment of patients with AR of deficient cold of lung Qi syndrome. It can significantly relieve patients' symptoms, improve patients' quality of life and reduce disease recurrence. It may play a role by regulating immune balance of Th17/Treg of patients and improving their immune function.

ABSTRACT

Human genetic prion diseases (gPrDs) are directly associated with mutations and insertions in the PRNP (Prion Protein) gene. We collected and analyzed the data of 218 Chinese gPrD patients identified between Jan 2006 and June 2020. Nineteen different subtypes were identified and gPrDs accounted for 10.9% of all diagnosed PrDs within the same period. Some subtypes of gPrDs showed a degree of geographic association. The age at onset of Chinese gPrDs peaked in the 50-59 year group. Gerstmann-Sträussler-Scheinker syndrome (GSS) and fatal familial insomnia (FFI) cases usually displayed clinical symptoms earlier than genetic Creutzfeldt-Jakob disease (gCJD) patients with point mutations. A family history was more frequently recalled in P105L GSS and D178N FFI patients than T188K and E200K patients. None of the E196A gCJD patients reported a family history. The gCJD cases with point mutations always developed clinical manifestations typical of sporadic CJD (sCJD). EEG examination was not sensitive for gPrDs. sCJD-associated abnormalities on MRI were found in high proportions of GSS and gCJD patients. CSF 14-3-3 positivity was frequently detected in gCJD patients. Increased CSF tau was found in more than half of FFI and T188K gCJD cases, and an even higher proportion of E196A and E200K gCJD patients. 63.6% of P105L GSS cases showed a positive reaction in cerebrospinal fluid RT-QuIC. GSS and FFI cases had longer durations than most subtypes of gCJD. This is one of the largest studies of gPrDs in East Asians, and the illness profile of Chinese gPrDs is clearly distinct. Extremely high proportions of T188K and E196A occur among Chinese gPrDs; these mutations are rarely reported in Caucasians and Japanese.

ABSTRACT

Objective@#To our knowledge, no definitive conclusion has been reached regarding the relationship between glucocorticoids and hypertension. Here, we aimed to explore the characteristics of glucocorticoids in participants with dysglycemia and hypertension, and to analyze their association with blood pressure indicators.@*Methods@#The participants of this study were from the Henan Rural Cohort study. A total of 1,688 patients 18-79 years of age were included in the matched case control study after application of the inclusion and exclusion criteria. Statistical methods were used to analyze the association between glucocorticoids and various indices of blood pressure, through approaches such as logistic regression analysis, trend tests, linear regression, and restricted cubic regression.@*Results@#The study population consisted of 552 patients with dysglycemia and hypertension (32.7%). The patients with co-morbidities had higher levels of serum cortisol ( @*Conclusions@#Serum deoxycortisol was positively correlated with systolic blood pressure, pulse pressure, mean arterial pressure, mean blood pressure, and mean proportional arterial pressure. Glucocorticoids (deoxycortisol and cortisol) increase the risk of hypertension in people with dysglycemia, particularly in those with T2DM.

ABSTRACT

Objective@#To investigate the molecular mechanism of high phosphorylation levels of cofilin-1 (p-CFL-1) associated with paclitaxel resistance in epithelial ovarian cancer (EOC) cells.@*Methods@#Cells displaying varying levels of p-CFL-1 and CFL-1 were created by plasmid transfection and shRNA interference. Cell inhibition rate indicating paclitaxel efficacy was assessed by Cell Counting Kit-8 (CCK-8) assay. Apoptosis was assessed by flow cytometry and protein levels were detected by western blotting. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure the expression levels of phosphokinases and phosphatases of CFL-1. Survival analysis evaluated the correlation between the prognosis of EOC patients and the levels of p-CFL-1 and slingshot-1 (SSH-1).@*Results@#High levels of p-CFL-1 were observed in EOC cells that survived treatment with high doses of paclitaxel. SKOV3 cell mutants with upregulated p-CFL-1 showed impaired paclitaxel efficacy, as well as decreased apoptosis rates and pro-survival patterns of apoptosis-specific protein expression. Cytoplasmic accumulation of p-CFL-1 inhibited paclitaxel-induced mitochondrial apoptosis. SSH-1 silencing mediated CFL-1 phosphorylation in paclitaxel-resistant SKOV3 cells. Clinically, the high level of p-CFL-1 and the low level of SSH-1 in EOC tissues were closely related to chemotherapy resistance and poor prognosis in EOC patients.@*Conclusion@#The SSH-1/p-CFL-1 signaling pathway mediates paclitaxel resistance by apoptosis inhibition in EOC and is expected to be a potential prognostic predictor.

ABSTRACT

@#Considering the increased use of electronic devices, the incidence of dry eye disease(DED)has been rising. The condition has seriously affected people's work and lives. DED, the most common ocular surface disease, can be caused by many factors. The meibomian gland dysfunction(MGD)is one of the main factors. Either abnormal secretions from the meibomian gland or an obstruction of the gland ducts can lead to evaporative dry eye. By summarising the relevant literature, this review addresses the aetiology, pathology, diagnosis and treatment of DED associated with MGD.

ABSTRACT

@#Uniportal video-assisted thoracic surgery (UniVATS) is a significant approach of mini-invasive surgery for lung cancer. UniVATS was first used for treatment of lung cancer in 2010. The European consensus and the Chinese consensus were published in 2019 and 2020 respectively. The latest Chinese consensus included the definition of UniVATS, indications for lung cancer treatment, safety and feasibility, surgical skills, learning curve, short-term and long-term results, providing suggestions for the standardization of uniportal video-assisted thoracic surgery, which are essential to improve the quality of surgery and reduce the incidence of related complications. The Chinese consensus also summarized the current status of subxiphoid UniVATS and non-intubated UniVATS for lung cancer. Considering the technical difficulties and challenges, the application of both technologies in clinical treatment has certain limitation. This article aims to give an interpretation of the results of the Chinese consensus and the similarities and to compare the differences with the European consensus, and to provide a reference for the majority of thoracic surgery colleagues.

ABSTRACT

Aberrant activation of NLRP3 inflammasome in colonic macrophages strongly associates with the occurrence and progression of ulcerative colitis. Although targeting NLRP3 inflammasome has been considered to be a potential therapy, the underlying mechanism through which pathway the intestinal inflammation is modulated remains controversial. By focusing on the flavonoid lonicerin, one of the most abundant constituents existed in a long historical anti-inflammatory and anti-infectious herb

ABSTRACT

OBJECTIVE@#High-fat diet (HFD) and inflammation are two key contributors to nonalcoholic fatty liver disease (NAFLD). Shenling Baizhu powder (SLBZP), a classical herbal compound, has been successfully used to alleviate NAFLD. However, its specific mechanisms are not fully understood. In this study, we assessed the anti-NAFLD effect of SLBZP in vivo.@*METHODS@#Rats were fed an HFD with or without SLBZP or with probiotics. At the end of week 16, an echo magnetic resonance imaging (EchoMRI) body composition analyser was used to quantitatively analyse body composition; a micro-computed tomography (micro-CT) imaging system was used to evaluate whole body and liver fat; and the Moor full-field laser perfusion imager 2 was used to assess liver microcirculation, after which, all rats were sacrificed. Then, biochemical indicators in the blood and the ultrastructure of rat livers were evaluated. Protein expression related to the liver Toll-like receptor 4 (TLR4)/Nod-like receptor family pyrin domain-containing 3 (NLRP3) signalling pathway was assessed using Western blot analysis. Further, high-throughput screening of 29 related inflammatory factors in liver tissue was performed using a cytokine array.@*RESULTS@#SLBZP supplementation reduced body weight, serum free fatty acid, and insulin resistance index (P < 0.05). It also ameliorated liver microcirculation and ultrastructural abnormalities. EchoMRI and micro-CT quantitative analyses showed that treatment with SLBZP reduced fat mass and visceral fat (P < 0.05 and P < 0.01, respectively). In addition, SLBZP decreased the expression of lipopolysaccharide (LPS)-activated TLR4/NLRP3 signalling pathway-related proteins and altered the expression levels of some inflammatory cytokines in liver tissues.@*CONCLUSION@#SLBZP can inhibit NLRP3 inflammasome activation and interleukin-1β release by suppressing LPS-induced TLR4 expression in rats with HFD-induced NAFLD. Thus, SLBZP may be beneficial for the prevention and treatment of inflammatory damage and associated diseases.

ABSTRACT

The inhibition of 5-α reductase type 2 (SRD5A2) by finasteride is commonly used for the management of urinary obstruction resulting from benign prostatic enlargement (BPE). Certain BPE patients showing no SRD5A2 protein expression are resistant to finasteride therapy. Our previous work showed that methylated cytosine-phosphate-guanine (CpG) islands in the SRD5A2 gene might account for the absence or reduction of SRD5A2 protein expression. Here, we found that the expression of the SRD5A2 protein was variable and that weak expression of the SRD5A2 protein (scored 0-100) occurred in 10.0% (4/40) of benign adult prostates. We showed that the expression of SRD5A2 was negatively correlated with DNA methyltransferase 1 (DNMT1) expression. In vitro SRD5A2-negative BPH-1 cells were resistant to finasteride treatment, and SRD5A2 was re-expressed in BPH-1 cells when SRD5A2 was demethylated by 5-Aza-2'-deoxycytidine (5-Aza-CdR) or N-phthalyl-L-tryptophan (RG108). Furthermore, we determined the exact methylation ratios of CpG dinucleotides in a CpG island of SRD5A2 through MassArray quantitative methylation analysis. Ten methylated CpG dinucleotides, including four CpG dinucleotides in the promoter and six CpG dinucleotides in the first exon, were found in a CpG island located from -400 bp to +600 bp in SRD5A2, which might lead to the silencing of SRD5A2 and the absence or reduction of SRD5A2 protein expression. Finasteride cannot exert a therapeutic effect on patients lacking SRD5A2, which may partially account for the resistance to finasteride observed in certain BPE patients.

ABSTRACT

With the continuous improvement of living conditions, increasing attention is being drawn to the genitourinary health of males, which has boomed the development of uroandrology in recent years. Refractory hemospermia, infertility, and perineal pain are commonly seen in some male patients, and mainly relied on medical imaging for diagnosis in the past, which, however, has a high pseudopositive rate and cannot give an etiological explanation. Patients with these diseases often adopt conservative treatments such as medication and physiotherapy, often with poor prognosis, and those suffering frequent recurrence used to be treated by transurethral resection, laparoscopic surgery or open surgery, which are now rarely employed due to their high rate of postoperative complications, slow recovery, and easy recurrence. In recent years, transurethral seminal vesiculoscopy has gained a wide application in the diagnosis and treatment of the above-mentioned uroandrological diseases and shown its advantages of high clinical effectiveness and low incidence of complications. The review updates on the indications, methods, skills and clinical application of transurethral seminal vesiculoscopy.

ABSTRACT

Objective@#To investigate the effect of isosorbide mononitrate (ISMN) targeted nanoparticles on inflammatory factors of sinusitis by establishing a rabbit model of rhinosinusitis.@*Methods@#Thirty healthy rabbits, male and female, weighing 2.5-3.5 kg, were randomly divided into 6 groups with 5 rabbits in each group. Group A was the control group. The model of rabbit sinusitis was established in group B to F, and CT was used to confirm the model was successful. After placing tubes into the maxillary sinus in the group C to F, saline, 45 mg/ml ISMN, 45 mg/ml ISMN nanoparticles and 45 mg/ml ISMN targeted nanoparticles were used to wash the maxillary sinus, respectively. Blood samples were collected from the ear vein of rabbits on day 7, 14, 21, 28, 35 and 42 after modeling respectively. Changes in the expression levels of inflammatory factors in rabbits during the modeling process and after drug washing were detected by ELISA. After the drug intervention, the maxillary sinus mucosa was taken for real-time quantitative PCR to detect the changes in the mRNA level of inflammatory factors. SPSS 22.0 software was used to process the data.@*Results@#Rabbit model of sinusitis was successfully established. ELISA showed that after the action of ISMN targeted nanoparticles of 1 week (42th day after modeling), the levels of (interleukin, IL) 4, IL-8, IL-17A and interferon γ (IFN-γ) in the blood were lower compared with that of 35th day after modeling, the difference was statistically significant (5.57±1.20 vs 19.73±0.68, 66.41±11.87 vs 154.68±13.13, 17.96±1.87 vs 28.23±0.80, 53.56±5.66 vs 111.93±7.29, all P<0.05). Compared with the ISMN nanoparticles and ISMN, the ISMN targeted nanoparticles reduced the levels of IL-4, IL-8, IL-17A and IFN-γ more obviously, the differences were statistically significant (13.26±1.43 vs 8.81±1.33 vs 7.14±2.16, 89.47±17.80 vs 41.07±7.77 vs 15.84±3.72, 10.28±2.07 vs 3.06±1.62 vs 1.82±0.90, 62.16±6.18 vs 35.12±4.62 vs 27.89±10.18, all P<0.05). Real-Time PCR showed that after the flushing of ISMN targeted nanoparticles, the levels of IL-4, IL-8, IL-17A and IFN-γ mRNA were lowest compared with that of the model group, ISMN nanoparticles and ISMN group.@*Conclusion@#ISMN targeted nanoparticles can reduce the level of inflammatory factors in rabbit sinusitis model.

ABSTRACT

Objective:To investigate the serum level of miR-126 in patients with hypertensive intracerebral hemorrhage and to elucidate its clinical significance in hypertensive cerebral hemorrhage.Methods:From January 2015 to December 2018, 60 patients with hypertensive cerebral hemorrhage were selected as observation group, and 60 healthy subjects were selected as control group in the People's Hospital of Lin'an Affiliated to Hangzhou Medical College.The serum levels of miR-126 were determined by reverse transcription-polymerase chain reaction (RT-PCR). The serum levels of C-reactive protein (CRP), tumor necrosis factor-ɑ (TNF-ɑ) and nuclear factor kappa B (NF-κB) were measured by enzyme-linked immunosorbent assay (ELISA).Results:The serum level of miR-126 in the observation group was lower than that in the control group [(0.46±0.11) vs.(1.00±0.13), t=24.562, P<0.05], and the serum levels of CRP, TNF-ɑ and NF-κB were higher than those in the control group[(8.74±0.69)mg/L vs.(3.98±0.61)mg/L, (62.43±8.26)μg/L vs.(31.28±6.54)μg/L, (19.73±1.02)μmol/L vs.(4.92±0.87)μmol/L, t=40.034, 22.902, 85.570, all P<0.05]. There were statistically significant differences in serum miR-126, CRP, TNF-ɑ, NF-κB levels among patients with different severity of hypertensive intracerebral hemorrhage[(0.57±0.09) vs.(0.44±0.12) vs.(0.36±0.11), (6.91±0.72)mg/L vs.(8.63±0.67)mg/L vs.(9.14±0.75)mg/L, (53.16±8.19)μg/L vs.(62.57±8.33)μg/L vs.(70.38±8.09)μg/L, (12.49±0.97)μmol/L vs.(19.58±1.11)μmol/L vs.(25.64±1.05)μmol/L, F=14.433, 41.379, 17.796, 623.893, all P<0.05], with the severity increased, the serum miR-126 level decreased, serum CRP, TNF-ɑ and NF-κB levels increased.The serum miR-126 level in patients with hypertensive cerebral hemorrhage of the poor prognosis group was lower than that of the good prognosis group [(0.53±0.10) vs.(0.38±0.12), t=5.279, P<0.05], and the serum levels of CRP, TNF-ɑ and NF-κB in the poor prognosis group were higher than those in the good prognosis group[(7.85±0.64)mg/L vs.(9.16±0.73)mg/L, (51.07±8.32)μg/L vs.(73.26±8.17)μg/L, (14.73±1.08)μmol/L vs.(26.52±0.99)μmol/L, t=7.392, 10.317, 43.424, all P<0.05]. The area of brain edema in patients with hypertensive intracerebral hemorrhage was negatively correlated with serum miR-126 ( r=-0.623, P<0.05), and positively correlated with serum CRP, TNF-ɑ and NF-κB ( r=0.581, 0.618, 0.642, all P<0.05). The serum miR-126 level was negatively correlated with CRP, TNF-ɑ and NF-κB in patients with hypertensive intracerebral hemorrhage ( r=-0.593, -0.624, -0.618, all P<0.05). Conclusion:The serum level of miR-126 is reduced in patients with hypertensive intracerebral hemorrhage, which may participate in the pathogenesis of hypertensive cerebral hemorrhage by participating in inflammatory reaction.The detection of serum miR-126 level has great value in evaluation of the severity and prognosis of hypertensive cerebral hemorrhage.

ABSTRACT

BACKGROUND: Core decompression and bone grafting is the main postoperative method in the treatment of ARCO stage II non-invasive necrosis of the femoral head, but there are risks of inaccurate location, incomplete or excessive removal of necrotic bone. OBJECTIVE: To observe the accuracy and safety of three-dimensional(3 D) printed navigation template assisted core decompression and bone grafting in the treatment of ARCO stage II non-traumatic femoral head necrosis. METHODS: Eighty patients(96 hips) of ARCO stage II non-traumatic femoral head necrosis were enrolled from January to November 2017 in Honghui Hospital Affiliated to Xi’an Jiaotong University. The patients were randomly divided into two groups. In the 3 D group, 40 cases(48 hips) received 3 D printed navigation template assisted core decompression and bone grafting. In the control group, 40 cases(48 hips) received core decompression and bone grafting(no navigation template). All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. The operation time, intraoperative fluoroscopy, and intraoperative blood loss were recorded, and X-ray examination results at 3, 6, 12, and 24 months after operation were observed. The femoral head survival rate, hip Harris score, and pain visual analogue scale score were evaluated. The efficacy was compared. RESULTS AND CONCLUSION:(1) Compared with the control group, the operation time was shortened from(132.57±14.86) minutes to(82.63±10.31) minutes; the number of intraoperative fluoroscopy was reduced from(16.80±2.15) times to(4.93±1.36) times; blood loss was reduced from(143.23±17.98) mL to(75.64± 16.23) mL in the 3 D group. Operation time, number of fluoroscopy, and blood loss were superior in the 3 D group than in the control group(P < 0.05).(2) The 24-month follow-up of imaging showed that only 2 cases of the femoral head collapsed in the 3 D group, but the hip joint function was acceptable. There was no artificial hip arthroplasty and the femoral head survival rate was 96%. In the control group, femoral head collapsed in 9 cases. Four of them had total hip arthroplasty due to limited hip joint activity, and the femoral head survival rate was 81%. The survival rate of the femoral head in the 3 D group was higher than that in the control group(P=0.024).(3) Compared with the control group, Harris score and visual analogue scale score were improved in the 3 D group(P < 0.05).(4) Applying 3 D printed navigation template to core decompression and bone grafting for ARCO stage II non-traumatic femoral head necrosis can reduce the operation time, intraoperative fluoroscopy and blood loss, and improve the accuracy and safety of intraoperative positioning.

ABSTRACT

BACKGROUND@#Epithelial to mesenchymal transition (EMT) is a key process in determining distant metastasis and intra-hepatic dissemination of hepatocellular carcinoma (HCC). Follistatin (FST) family members are considered to be an attractive therapeutic targets and prognostic indicators in cancers. As a derivative of FST, Follistatin Like 5 (FSTL5) may play a similar role in HCC cells. This study aimed to investigate the expression and function of FSTL5 in HCC and its role in EMT.@*METHODS@#FSTL5, E-cadherin and vimentin in HCC, and paracancerous tissues were detected by immunohistochemistry. Correlation of FSTL5 expression with overall survival was assessed. The proliferation and invasion of HCC cell lines SK-Hep1 and MHCC-LM3 were analyzed by cell counting kit-8 and Transwell assays. The expression of FSTL5, E-cadherin, and vimentin in HCC cells was examined by polymerase chain reaction and Western blot analysis. T-test was used to analyze the difference in proliferation and invasion ability between groups. The Spearman rank correlation test was used to detect the correlation between the expression of FSTL5 and E-cadherin or vimentin.@*RESULTS@#The expression of FSTL5 in HCC was lower than that in paracancerous tissues (9.97% vs. 82.55%, χ = 340.15, P < 0.001). Patients with high FSTL5 expression had a better prognosis (χ = 8.22, P = 0.004) and smaller tumor diameter (χ = 45.52, P < 0.001), less lymph node metastasis (χ = 5.58, P = 0.02), earlier tumor node metastasis stage (χ = 11.29, P = 0.001), a reduced number of tumors (χ = 5.05, P = 0.02), lower alpha-fetoprotein value (χ = 24.36, P < 0.001), more probability of hepatitis carrying (χ = 40.9, P < 0.001), and better liver function grade (χ = 5.21, P = 0.02). Immunohistochemistry showed that FSTL5 expression in HCC tissues was positively correlated with E-cadherin expression (r = 0.38, P < 0.001) and negatively correlated with vimentin expression (r = -0.385, P < 0.001). Furthermore, over-expression of FSTL5 up-regulated the expression of E-cadherin and down-regulated the expression of vimentin in SK-Hep1 (negative control [NC] vs. FSTL5-interfering group [Lv-FSTL5]: E-cadherin [t = 45.03, P < 0.001], vimentin [t = 67, P < 0.001]) and MHCC-LM3 (NC vs. Lv-FSTL5: E-cadherin [t = 50, P < 0.001], vimentin [t = 72.75, P < 0.001]) cells at mRNA level. The same as protein level. In addition, the over-expression of FSTL5 inhibited the proliferation (NC vs. Lv-FSTL5: SK-Hep1, 3 d [t = 7.324, P = 0.018], 4 d [t = 6.23, P = 0.021], 5 d [t = 10.21, P = 0.003]; MHCC-LM3, 3 d [t = 4.32, P = 0.037], 4 d [t = 7.49, P = 0.012], 5 d [t = 9.3661, P = 0.009]) and invasion (NC vs. Lv-FSTL5: SK-Hep1, t = 21.57, P < 0.001; MHCC-LM3, t = 18.04, P < 0.001) of HCC cells.@*CONCLUSIONS@#Down-regulation of FSTL5 may contribute to EMT of HCC, and FSTL5 is a potential target in the treatment of HCC.

ABSTRACT

Inthomycins are polyketide antibiotics which contain a terminal carboxamide group and a triene chain. Inthomycin B (1) and its two new analogues 2 and 3 were isolated from the crude extract of Streptomyces pactum L8. Identification of the gene cluster for inthomycin biosynthesis as well as the N-labeled glycine incorporation into inthomycins are described. Combined with the gene deletion of the rare P450 domain in the NRPS module, a formation mechanism of carboxamide moiety in inthomycins was proposed via an oxidative release of the assembly chain assisted by the P450 domain.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of platelet rich plasma (PRP) combined with β tricalcium phosphate bioceramic bone in the treatment of non traumatic necrosis of the femoral head in ARCO stageⅡ.@*METHODS@#From January 2017 to December 2018, 100 patients (160 hips) with ARCO stageⅡnon traumatic necrosis of the femoral head were divided into PRP group and control group. In PRP group, 50 patients (80 hips), 22 males and 28 females, aged from 18 to 65 (43.47± 7.23) years, with a course of 4 to 18 (15.8±2.9) months, underwent core decompression and bone grafting combined with PRP implantation. There were 50 cases (80 hips) in the control group, including 27 males and 23 females, aged 20 to 63 (45.72± 7.43) years, and the course of disease was 6 to 19 (14.9±3.8) months. Hip X-ay film was followed up after operation. Harris score and VAS score were used to evaluate the curative effect, and the survival rate of hip joint was recorded.@*RESULTS@#All patients had good wound healing, no infection, thrombosis and other complications. All patients were followed up for 12 to 14 (12.0±0.4) months. Twelve months after operation, the image expression of PRP group was better than that of control group(@*CONCLUSION@#Platelet-rich plasma(PRP) combined with artificialbone for core decompression and bone grafting can change the situation of simple artificial bone implantation and uncertain curative effect, improve the success rate of this operation, effectively reduce the collapse rate of femoral head necrosis in the early and middle stage, delay or even avoid hip replacement.

ABSTRACT

To systematically evaluate the efficacy of traditional Chinese medicine(TCM) compounds combined with levodopa medicine in the treatment of Parkinson's disease(PD), and screen basic herbs to provide certain evidence-based medical proof and program for better guidance on clinical drug use. Six databases were searched to screen out the randomized controlled trial on the TCM compounds combined with levodopa medicine in the treatment of PD. Literature quality of the included studies was evaluated by improved Jadad rating scale, and the Meta-analysis was performed by RevMan 5.3 software. After the data of the basic TCM compounds involved were sorted out, the strong association rules were found by using Apriori algorithm of SPSS Modeler 18.0 software, and then the basic herbs for the treatment of PD could be picked out. A total of 20 studies were eventually included, involving 1 784 patients. Ten studies were of high-quality literature, Jadad score≥4 points. Meta-analysis showed that efficacy of TCM combined with levodopa medicine was better than levodopa medicine alone in lowering Unified Parkinson's Disease Rating Scale(UPDRS) score: UPDRS Ⅰ(MD=-0.43, 95%CI[-0.62,-0.24], P<0.000 1), UPDRS Ⅱ(MD=-2.72, 95%CI[-3.24,-2.21], P<0.000 01), UPDRS Ⅲ(MD =-1.97, 95%CI[-2.69,-1.25], P<0.000 01), UPDRS Ⅳ(MD=-0.28, 95%CI[-0.46,-0.11], P=0.002). And the improvement in UPDRS score reduction rate of TCM combined with levodopa medicine was better than that in levodopa medicine alone: effective rate(OR=4.81, 95%CI[3.50, 6.62], P<0.000 01). Data mining results showed that the basic prescription for treating PD consisted of Paeoniae Radix Alba-Rehmanniae Radix Praeparata-Gastrodiae Rhizoma in general. According to each part of UPDRS, the basic prescription for treating mentation, behavior and mood(UPDRS Ⅰ) consists of Paeoniae Radix Alba-Rehmanniae Radix Praeparata-Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle, Among which Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle might have unique efficacy. The basic prescriptions for treating UPDRS Ⅱ and UPDRS Ⅲ consisted of Paeoniae Radix Alba-Rehmanniae Radix Praeparata, or Chuanxiong Rhizoma-Angelicae Sinensis Radix(two drug combinations). However, in the treatment of UPDRS Ⅳ, the drugs were scattered. But due to the limitations in the quantity and quality of clinical studies, the results obtained still need further research and clinical confirmation of its efficacy.
