ABSTRACT

ABSTRACT Purpose: The regulatory effect of microRNA on diseases has been confirmed. This study aimed to evaluate the expression of microRNA-210-3p in age-related cataracts and assess the effect of abnormal miR-210-3p expressions on H2O2-induced SAR01/04 cells. Methods: Reverse-transcription quantitative polymerase chain reaction method was performed to assess the levels of miR-210-3p in aqueous humor samples. Receiver operating characteristic analysis was employed to assess the discrimination ability of miR-210-3p between patients with age-related cataracts and healthy people, and Pearson correlation analysis was used to identify the correlation between miR-210-3p and oxidative stress indices such as superoxide dismutase, glutathione peroxidase, malonaldehyde. Cell counting kit-8 assay and Transwell assay were used to estimate the biological function of H2O2-induced age-related cataract cell model. The levels of oxidative stress indices such as superoxide dismutase, glutathione peroxidase, and malonaldehyde were measured to evaluate the degree of oxidative stress damage in the age-related cataract cell model. The relationship between miR-210-3p and its target gene was verified by luciferase reporter gene analysis. Results: The miR-210-3p expression was elevated in the aqueous humor of patients with age-related cataracts. A high miR-210-3p expression showed a high diagnostic value for age-related cataracts and was significantly associated with the level of oxidative stress markers in patients with age-related cataracts. The inhibition of miR-210-3p can reverse oxidative stress stimulation and adverse effects on H2O2-induced cell function. Conclusions: The results suggested that miR-210-3p could promote cell viability, cell migration, and oxidative stress by targeting autophagy-related gene 7 in in vitro age-related cataract cell model.

O ensaio de contagem de células kit-8 (cck-8) e o ensaio no sistema Transwell foram utilizados para estimar a função biológica do formato de células de catarata relacionada com a idade induzida por H2O2. Os níveis de índices de estresse oxidativo como superóxido dismutase, glutationa peroxidase e malonaldeído foram detectados para avaliar o grau de dano do estresse oxidativo em formato de células de catarata relacionada à idade. A relação entre miR-210-3p e seu gene alvo foi verificada por análise do gene repórter luciferase. Resultados: A expressão miR-210-3p foi elevada no humor aquoso de pacientes com catarata relacionada à idade. A expressão miR-210-3p altamente expressiva mostrou alto valor diagnóstico para catarata relacionada à idade e foi significativamente associado ao nível de marcadores de estresse oxidativo em pacientes com catarata relacionada à idade. A inibição de miR-210-3p pode reverter a estimulação do estresse oxidativo e os efeitos adversos da função celular induzida por H2O2. Conclusões: Esses dados sugeriram que a expressão miR-210-3p poderia promover a viabilidade celular, migração celular e estresse oxidativo ao direcionar genes ATG 7 relacionados à autofagia em modelo in vitro de células de catarata relacionadas à idade.

ABSTRACT

Objective: To investigate the oncologic and surgical safety of the fused fascia method for immediate breast reconstruction with implants. Methods: The clinical data of 343 patients with immediate breast reconstruction with implants in Tianjin Medical University Cancer Hospital from 2014-2017 were retrospectively analyzed to compare the 5-year local recurrence-free survival, 5-year disease-free survival and 5-year overall survival of patients with breast reconstruction by fusion fascia and other methods, and to analyze the complication incidences of implant removal between different implant groups. Results: Of the 343 patients with breast reconstruction, 95 were in the fused fascia group (fascia group) and 248 were in the non-fascia group (25 in the bovine pericardial patch group and 223 in the muscle flap group). At a median follow-up of 49 months, the differences in 5-year local recurrence-free survival (90.1% and 94.9%, respectively), 5-year disease-free survival (89.2% and 87.6%, respectively), and 5-year overall survival (95.2% and 95.1%, respectively) between patients in the fascial and non-fascial groups were not statistically significant (P>0.05). The complication incidence of implant removal was 24.0% (6/25) in the patch group and 2.1% (2/95) and 2.2% (5/223) in the fascia and muscle flap groups, respectively. Conclusion: Immediate breast reconstruction with fused fascial combined with implant is safe and feasible, less invasive than muscle flaps, more economical and with fewer complications than patches.

ABSTRACT

ObjectiveTo study the mechanism of Renshen Baidusan in regulating adenylate-activated protein kinase (AMPK)/Unc-51-like kinase 1 (ULK1) autophagy pathway to inhibit mucosal barrier damage in the mouse model of ulcerative colitis (UC). MethodSixty SD rats were randomized into normal, model, sulfasalazine enteric-coated tablets (0.312 5 g·kg-1, western medicine), and high-, medium-, and low-dose (31.2, 15.6, 7.8 g·kg-1, respectively) Renshen Baidusan groups. The UC model was induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS)/50% ethanol. The drugs were administrated by gavage for 2 weeks, and then the histopathological changes of the colon were examined. Real-time quantitative polymerase chain reaction was conducted to measure the mRNA level of AMP-activated protein kinase subunit alpha (AMPKα). Western blot was employed to determine the protein levels of closure protein (Occludin), compact linking protein-2 (Claudin-2), autophagy marker p62, microtubule-associated protein 1 light chain 3B (LC3B), phosphorylated AMPK (p-AMPK), and phosphorylated ULK1 (p-ULK1). ResultCompared with the normal group, the model group showed increased colon injury score (P<0.05), down-regulated mRNA level of AMPKα (P<0.05) and protein levels of p-AMPK, p-ULK1, and Occludin, decreased LC3Ⅱ/Ⅰ ratio (P<0.05), and up-regulated protein levels of p62 and Claudin-2 (P<0.05). Compared with the model group, all the doses of Renshen Baidusan lowered the colon injury score, up-regulated the mRNA level of AMPKα and the protein levels of p-AMPK, p-ULK1, and Occluding, increased LC3Ⅱ/Ⅰ ratio, and down-regulated the protein levels of p62 and Claudin-2. Moreover, the medium-dose group showed a significant intervention effect (P<0.05). ConclusionRenshen Baidusan can protect the intestinal mucosal barrier from damage, and the medium dose showed the best efficacy. It may activate the AMPK/ULK1 pathway to accelerate the transformation of LC3Ⅰ to LC3Ⅱ and promote the degradation of p62, so as to improve the function of Occludin and Claudin-2 and repair the mechanical damage of the intestinal barrier.

ABSTRACT

ObjectiveTo explore the mechanisms of internal treatment (Renshen Baidusan), external treatment (Yurui Enema), and combination of the two methods in treating intestinal mucosal injury in the rat model of ulcerative colitis (UC) from the changes of phosphatidylinositol-3 kinase (PI3K)/protein kinase B (Akt)/nuclear factor-κB (NF-κB) pathway. MethodFifty SPF-grade SD rats were randomized into blank, model, Renshen Baidusan (15.6 g·kg-1), Yurui Enema (25 g·kg-1), and combined treatment (15.6 g·kg-1 Renshen Baidusan + 25 g·kg-1 Yurui Enema) groups (n=10). The rat model of UC was established in other groups except the blank group by 2,4, 6-trinitrosulfonic acid (TNBS)/ethanol. The rats were administered with corresponding drugs once a day for 14 consecutive days since the 8th day after modeling. The histopathological changes of colon were observed by hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, interleukin (IL)-4, and IL-10 in the colon tissue. The apoptosis of colon epithelial cells was detected by terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL). The location and expression of B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), TNF-α, and IL-6 in the colon tissue were examined by immunohistochemistry. Real-time quantitative fluorescence polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of the proteins in the PI3K/Akt/NF-κB pathway in the colon tissue. ResultIn the model group, HE staining showed a large number of inflammatory cell infiltration in the mucosa and submucosa. Compared with the blank group, the model group showed elevated levels of TNF-α and IFN-γ and lowered levels of IL-4 and IL-10 in the colon tissue, increased apoptosis rate of colon epithelial cells, increased positive expression of Bax, TNF-α, and IL-6, and decreased positive expression of Bcl-2 (P<0.05). Moreover, the model group showed up-regulated mRNA levels of PI3K, Akt, and NF-κB and protein levels of PI3K, p-PI3K, Akt, p-Akt, p65, p-p65, Bax, and cleaved Caspase-3, increased Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios, and down-regulated protein levels of NF-κB suppressor protein α(IκBα), Bcl-2, and Caspase-3 in the colon tissue (P<0.05). Compared with the model group, the internal treatment, the external treatment, and the combination (referred to as the three groups) alleviated the colonic mucosal injury, lowered the levels of TNF-α and IFN-γ and elevated the levels of IL-4 and IL-10 in the colon tissue, decreased the apoptosis rate of colon cells, inhibited the positive expression of Bax, TNF-α, and IL-6, and promoted the positive expression of Bcl-2 (P<0.05). Furthermore, the combination group down-regulated the mRNA level of PI3K (P<0.05). The three groups down-regulated the mRNA levels of Akt and NF-κB and the protein levels of p-PI3K, Akt, p-Akt, p65, p-p65, Bax, and cleaved Caspase-3 in the colon tissue, decreased the Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios, and up-regulated the protein levels of IκBα, Bcl-2, and Caspase-3 (P<0.05). ConclusionRenshen Baidusan, Yurui Enema, and their combination may inhibit the activation of PI3K/Akt/NF-κB signaling pathway and regulate the expression of genes and proteins related to this pathway to achieve anti-inflammatory and anti-apoptotic effects, thus restoring the intestinal mucosal barrier function of UC rats.

ABSTRACT

ObjectiveTo explore the mechanism of Renshen Baidusan in repairing intestinal mucosa in ulcerative colitis (UC) by regulating autophagy to scavenge peroxides. MethodThe mouse model of UC was induced by free drinking of 3.0% dextran sulphate sodium (DSS) solution. Sixty male C57BL/6J mice were randomized into normal, model, mesalazine (0.3 g·kg-1), and high-, medium-, and low-dose (12.35, 8.22, 4.11 g·kg-1, respectively) Renshen Baidusan groups (n=10). The mice were administrated with corresponding drugs by gavage for 7 consecutive days. The colon tissue was stained with hematoxylin-eosin (HE) to reveal the pathological changes, and Alcian blue-Periodic acid Scheff (PAS/AB) staining was employed to observe the goblet cell changes. The fluorescence expression of reactive oxygen species (ROS) in the colon tissue was detected by the immunofluorescence assay. The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) were measured by the biochemical methods. Western blot was employed to determine the expression levels of proliferating cell nuclear antigen (PCNA), microtubule-associated protein 1 light chain 3 (LC3), leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), and p62. ResultDestroyed mucosal epithelial structure, intestinal gland destruction, loss of goblet cells, and massive infiltration of inflammatory cells appeared in the model group. Compared with the normal group, the model group showed increased tissue damage injury (TDI) score of the colon tissue, decreased SOD activity and LC3Ⅱ/Ⅰ, PCNA value, and elevated levels of p62, MDA, ROS, and LGR5 (P<0.05). Compared with the model group, different doses of Renshen Baidusan decreased the TDI score, promoted the generation of new goblet cells, elevated the levels of PCNA, LGR5, SOD, and LC3Ⅱ/Ⅰ, and lowered the levels of p62, MDA, and ROS (P<0.05). Moreover, the low dose group showed the best performance (P<0.05). ConclusionRenshen Baidusan can promote intestinal epithelial repair by activating intestinal autophagy, alleviating oxidative stress, and promoting intestinal stem cell proliferation and differentiation.

ABSTRACT

Objective To prepare a sustained-release membrane with longer adhesion time and dissolution time, and compare it with the commercially available oral ulcer membrane. Method Adhesion strength, adhesion time, swelling coefficient, dissolution time, etc. were used as the inspection indicators, and a combination of single factor inspection and analytic hierarchy process were used to screen the membrane -forming materials. The dispersion method of clotrimazole, ornidazole and borneol were investigated to prevent the drug from seed out. The method of combining orthogonal experiment and analytic hierarchy process were used to optimize the dosage of CMC-Na, PVA-1788 and glycerin; and the commercial products were compared. Results Through single-factor investigation and orthogonal experiment, the optimal ratio of excipients was selected as CMC-Na∶PVA-1788∶glycerol (3∶1∶0.08). The water-insoluble component clotrimazole, ornidazole and borneol were treated by precipitation in liquid with good effect. The best method was used to prepare the membrane. The adhesion strength was 102 g. The adhesion time was 55 min. The swelling coefficient was 1 939.52. The average dissolution time was 110 min. The appearance was white and the surface was free of bubbles, soft and elastic. The membrane forming time at 60 ℃ was 300 min and the demolding effect was better which could be completely peeled off with moderate thickness. Conclusion The oral ulcer membrane developed in this method has good appearance, comfortable use, strong adhesion, long adhesion time and dissolution time, and could stay on the ulcer surface for a long time to form physical isolation, and slowly release the drug during the dissolution process, which could play the role of long-term pain relief, antibacterial, anti-inflammatory and promote healing effects on oral ulcers.

ABSTRACT

Objective To investigate the long non-coding RNA(lncRNA) MRAK08838 regulates macrophage function to influence the development of asthmatic airway inflammation. Methods MRAK088388 gene knockout (MRAK088388-/-) mouse model was prepared and allergic asthma was induced by dust mite protein Dermatophagoides farinae 1 (Der f1). The mice were sacrificed after 28 days of modeling, and serum was collected to measure IgE and IgG. The FinePointe RC system was used to measure airway hyperresponsiveness and evaluate lung function in mice. Lung tissue was taken for HE staining, and periodic acid-Schiff (PAS) staining was used to evaluate inflammatory infiltration and mucus secretion in mouse lungs. Fluorescence quantitative PCR was used to detect the expression level of lncRNA MRAK08838 in bronchoalveolar lavage fluid (BALF) cells and lung tissue of asthmatic mice. ELISA was used to detect the levels of inflammatory cytokines IFN-γ, IL-4, IL-5, IL-13, IL-10 and IL-17A. Flow cytometry was used to evaluate the phenotype of macrophages in BALF and lung tissue, as well as the proportion of neutrophils, eosinophils, and alveolar macrophages. The changes of the above indicators were detected in mice by adoptive transfer of bone marrow-derived macrophages (BMDM). Results Under the challengle of Der f1, MRAK088388-/- mice showed reduced allergic airway inflammation, including reduced eosinophils in BALF and reduced production of IgE and IgG1. In addition, Der f1-treated MRAK088388-/- mice had fewer M2 macrophages than wild-type asthmatic mice. Wild-type mouse BMDM (M0) and Der f1-treated MRAK088388-/- mice also showed mild inflammatory response. Conclusion Knockout of MRAK088388 alleviates airway inflammation in asthmatic mice by inhibiting M2 polarization of airway macrophages.

ABSTRACT

To investigate the intervention effect and mechanism of Zhenwu Decoction on diabetic nephropathy(DN) mice of spleen-kidney Yang deficiency syndrome based on the Rho-associated coiled-coil kinase(ROCK)/IκB kinase(IKK)/nuclear factor-κB(NF-κB) pathway. Ninety-five 7-week-old db/db male mice and 25 7-week-old db/m male mice were fed adaptively for one week. The DN model of spleen-kidney Yang deficiency syndrome was induced by Dahuang Decoction combined with hydrocortisone by gavage, and then the model was evaluated. After modeling, they were randomly divided into a model group, high-dose, medium-dose, and low-dose Zhenwu Decoction groups(33.8, 16.9, and 8.45 g·kg~(-1)·d~(-1)), and an irbesartan group(25 mg·kg~(-1)·d~(-1)), with at least 15 animals in each group. The intervention lasted for eight weeks. After the intervention, body weight and food intake were measured. Serum crea-tinine(Scr), blood urea nitrogen(BUN), fasting blood glucose(FBG), urinary albumin(uALb), and urine creatinine(Ucr) were determined. The uALb/Ucr ratio(ACR) and 24 h urinary protein(UTP) were calculated. Renal pathological morphology was evaluated by HE staining and Masson staining. The levels of key molecular proteins in the ROCK/IKK/NF-κB pathway were detected by Western blot. Enzyme-linked immunosorbent assay(ELISA) was used to detect interleukin-1β(IL-1β), interleukin-6(IL-6), interleukin-8(IL-8), interleukin-10(IL-10), and tumor necrosis factor-α(TNF-α). Compared with the blank group, the model group showed increased content of BUN, uALb, and SCr, increased values of 24 h UTP and ACR, decreased content of Ucr(P<0.05), enlarged glomeruli, thickened basement membrane, mesangial matrix proliferation, inflammatory cell infiltration, and collagen fiber deposition. The protein expression of ROCK1, ROCK2, IKK, NF-κB, phosphorylated IKK(p-IKK), phosphorylated NF-κB(p-NF-κB), and phosphorylated inhibitor of NF-κB(p-IκB) increased(P<0.05), while the protein expression of inhibitor of NF-κB(IκB) decreased(P<0.05). The levels of inflammatory factors IL-1β, IL-6, IL-8, and TNF-α increased(P<0.05), while the level of IL-10 decreased(P<0.05). Compared with the model group, the groups with drug treatment showed decreased levels of BUN, uALb, SCr, 24 h UTP, and ACR, increased level of Ucr(P<0.05), and improved renal pathological status to varying degrees. The high-and medium-dose Zhenwu Decoction groups and the irbesartan group showed reduced protein expression of ROCK1, ROCK2, IKK, NF-κB, p-IKK, p-NF-κB, and p-IκB in the kidneys(P<0.05), increased protein expression of IκB(P<0.05), decreased levels of serum inflammatory factors IL-1β, IL-6, IL-8, and TNF-α(P<0.05), and increased level of IL-10(P<0.05). Zhenwu Decoction can significantly improve renal function and renal pathological damage in DN mice of spleen-kidney Yang deficiency syndrome, and its specific mechanism may be related to the inhibition of inflammatory response by down-regulating the expression of key molecules in the ROCK/IKK/NF-κB pathway in the kidney.

ABSTRACT

Under the national policy background of traditional Chinese medicine(TCM)registration review and approval reform, TCM preparations in medical institutions(hereinafter referred to as medical institution preparations) have human use experience, conform to the characteristics of TCM clinical practice, and have advantages in the research and development of innovative Chinese medicines. Therefore, the research and development mode based on clinical experience prescription-medical institution preparations-innovative Chinese medicines has attracted widespread attention from the industry. However, in the process of development and use of medical institution preparations, there are generally clinical problems that restrict their transformation into innovative Chinese medicines, resulting in a relatively weak collection basis of human use experience and insufficient clinical evidence for supporting the research and development of new TCM medicines. In this paper, on the basis of sorting out the supporting regulations and relevant technical requirements of human use experience, and analyzing the clinical problems restricting the transformation of medical institution preparations, it provides suggestions for medical institutions to carry out high-quality research on human use experience of preparations in the process of TCM clinical practice from the aspects of continuously exploring clinical value, improving the construction of information system, focusing on the TCM clinical practice and giving full play to the advantages of discipline cooperation. By realizing the whole life cycle management of medical institution preparations based on three-combination evaluation evidence system, we can promote the transformation of medical institution preparations into innovative Chinese medicines.

ABSTRACT

OBJECTIVE@#Omicron, a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant, is responsible for numerous infections in China. This study investigates the association between the use of Seven-Flavor Herb Tea (SFHT) and the risk of SARS-CoV-2 infection to develop precise and differentiated strategies for control of the coronavirus disease 2019 (COVID-19).@*METHODS@#This case-control study was conducted at shelter hospitals and quarantine hotels in China. A total of 5348 laboratory-confirmed COVID-19 patients were enrolled between April 1 and May 31, 2022, while 2190 uninfected individuals served as healthy controls. Structured questionnaires were used to collect data on demographics, underlying diseases, vaccination status, and use of SFHT. Patients were propensity-score-matched using 1:1 nearest-neighbor matching of the logit of the propensity score. Subsequently, a conditional logistic regression model was used for data analysis.@*RESULTS@#Overall, 7538 eligible subjects were recruited, with an average age of [45.54 ± 16.94] years. The age of COVID-19 patients was significantly higher than that of uninfected individuals ([48.25 ± 17.48] years vs [38.92 ± 13.41] years; t = 22.437, P < 0.001). A total of 2190 COVID-19 cases were matched with uninfected individuals at a 1:1 ratio. The use of SFHT (odds ratio = 0.753, 95% confidence interval: 0.692, 0.820) was associated with a lower risk of SARS-CoV-2 infection compared to untreated individuals.@*CONCLUSION@#Our findings suggest that taking SFHT reduces the risk of SARS-CoV-2 infection. This is a useful study in the larger picture of COVID-19 management, but data from large-sample multi-center, randomized clinical trial are warranted to confirm the finding.

ABSTRACT

OBJECTIVE@#To explore the effect of facet joint degeneration in adjacent segments on the incidence of adjacent segment disease (ASD) after lumbar fusion and fixation.@*METHODS@#A retrospective analysis was performed on 138 patients who underwent L5S1 posterior lumbar interbody fusion (PLIF) from June 2016 to June 2019. Patients were divided into a degeneration group (68 cases) and a non-degenerative group (70 cases) based on the presence or absence of L4,5 facet joint degeneration before surgery (graded using the Weishaupt standard). Age, gender, body mass index (BMI), follow-up time, and preoperative L4,5 intervertebral disc degeneration (graded using the Pfirrmann standard) were collected for both groups. Clinical outcomes were evaluated using the visual analogue scale (VAS) and Oswestry disability index (ODI) at 1 and 3 months after surgery. The incidence and time of ASD after surgery were analyzed.@*RESULTS@#There were no significant differences between the two groups in age, gender, BMI, follow-up time, or preoperative L4,5 intervertebral disc degeneration. Both groups showed significant improvement in VAS and ODI at 1 and 3 months after surgery (P<0.001), with no significant difference between the groups(P>0.05). However, there was a statistically significant difference in the incidence and timing of ASD between the groups (P<0.05). The degeneration group had 2 cases of ASD in gradeⅠdegeneration, 4 cases of ASD in gradeⅡdegeneration, and 7 cases of ASD in grade Ⅲ degeneration. There was a statistically significant difference between the number of patients with grade Ⅲ degeneration and those with gradesⅠandⅡASD (P<0.0167, Bonferroni correction).@*CONCLUSION@#Preoperative degeneration of adjacent articular processes will increase the risk of ASD after lumbar fusion fixation, whereas gradeⅢ degeneration will further increase the risk.

ABSTRACT

OBJECTIVE@#To investigate the effect of body mass index (BMI) on the short-term effectiveness of high tibial osteotomy (HTO) in the treatment of varus knee arthritis.@*METHODS@#The clinical data of 84 patients (84 knees) with varus knee arthritis treated with HTO between May 2016 and August 2020 were retrospectively analyzed. According to BMI, the patients were divided into normal group (32 patients in group A, BMI<25 kg/m 2), overweight group (27 patients in group B, BMI>30 kg/m 2), and obese group (25 patients in group C, BMI>30 kg/m 2). The BMI of groups A, B, and C were (23.35±0.89), (26.65±1.03), and (32.05±1.47) kg/m 2, respectively. There was no significant difference ( P>0.05) in gender, age, surgical side, disease duration, and preoperative Hospital for Special Surgery (HSS) score, visual analogue scale (VAS) score, knee range of motion, and hip-knee-ankle angle (HKA) between groups. The operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation were recorded and compared between groups. The improvement of knee joint function and pain status were evaluated by knee joint HSS score, knee range of motion, and VAS score before and after operation, and measuring the HKA of patients on X-ray film. During the follow-up, the X-ray films of the knee joint were reexamined to observe the position of the internal fixator and the healing of osteotomy.@*RESULTS@#All patients completed the operation successfully and were followed up 8-40 months (mean, 19.3 months). There was no significant difference in follow-up time, operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation between groups ( P>0.05). No operative complications such as severe vascular or nerve injury occurred. After operation, deep venous thrombosis of lower extremities occurred in 1 case in groups A and B respectively, and fat liquefaction of surgical incision occurred in 2 cases in group C. There was no significant difference in the incidence of perioperative complications between groups (3.1% vs. 3.7% vs. 8.0%) ( P=0.689). During the follow-up, there was no bone nonunion, plate fracture or loosening. At last follow-up, HSS score, VAS score, knee range of motion, and HKA significantly improved in the 3 groups when compared with those before operation ( P<0.05), but there was no significant difference in the differences of the above indexes between groups before and after operation ( P>0.05).@*CONCLUSION@#BMI does not affect the short-term effectiveness of HTO in the treatment of varus knee arthritis. HTO can be selected for overweight and obese patients after standard medical treatment is ineffective.

ABSTRACT

Objective Primary ovarian small cell carcinoma of pulmonary type (SCCOPT) is a rare ovarian tumor with a poor prognosis. The platinum-based chemotherapy is the standard treatment. However, there is little research on the clinical characteristics of SCCOPT and the potential benefits of other treatments due to its low incidence. The study aims to investigate clinicopathological characteristics and treatment of SCCOPT.Methods We summarized the clinical, imaging, laboratorical and pathological characteristics of 37 SCCOPT cases, in which 6 cases were admitted to the Gansu Provincial Hospital from the year of 2008 to 2022 and 31 cases reported in 17 English and 3 Chinese literatures.Results The median age of the studied SCCOPT cases (n=37) was 56.00 (range, 22-80) years. Almost 80% of them had a stage Ⅲ or Ⅳ tumor. All patients underwent an operation and postoperative chemotherapy. Nevertheless, all cases had a poor prognosis, with a median overall survival time of 12 months. Immunohistochemically, the SCCOPT of all patients showed positive expressions of epithelial markers, such as CD56 and sex-determining region of Y chromosome-related high-mobility-group box 2 (SOX-2), and negative expressions of estrogen receptor, progesterone receptor, vimentin, Leu-7, and somatostatin receptor 2. The tumor of above 80% cases expressed synaptophysin. Only a few cases expressed neuron-specific enolase, chromogranin A, and thyroid transcription factor-1. Conclusions SCCOPT had a poor prognosis. SOX-2 could be a biomarker to be used to diagnose SCCOPT.

ABSTRACT

Diabetic kidney disease is an important microvascular complication of diabetes and the leading cause of end-stage renal disease. Its pathological characteristics mainly include epithelial mesenchymal transition(EMT) in glomerulus, podocyte apoptosis and autophagy, and damage of glomerular filtration barrier. Transforming growth factor-β(TGF-β)/Smad signaling pathway is specifically regulated by a variety of mechanisms, and is a classic pathway involved in physiological activities such as apoptosis, proliferation and differentiation. At present, many studies have found that TGF-β/Smad signaling pathway plays a key role in the pathogenesis of diabetic kidney disease. Traditional Chinese medicine has significant advantages in the treatment of diabetic kidney disease for its multi-component, multi-target and multi-pathway characteristics, and some traditional Chinese medicine extracts, traditional Chinese medicines and traditional Chinese medicine compound prescription improve the renal injury of diabetic kidney disease by regulating TGF-β/Smad signaling pathway. This study clarified the mechanism of TGF-β/Smad signaling pathway in diabetic kidney disease by expounding the relationship between the key targets of the pathway and diabetic kidney disease, and summarized the research progress of traditional Chinese medicine in the treatment of diabetic kidney disease by interfering with TGF-β/Smad signaling pathway in recent years, to provide reference for drug research and clinical treatment of diabetic kidney disease in the future.

ABSTRACT

In order to comprehensively evaluate the quality of Viticis Fructus, this study established HPLC fingerprints and evaluated the quality of 24 batches of Viticis Fructus samples from different species by similarity evaluation and multivariate statistical analysis(PCA, HCA, PLS-DA). On this basis, an HPLC method was established to compare the content differences of the main components, including casticin, agnuside, homoorientin, and p-hydroxybenzoic acid. The analysis was performed on the chromatographic column(Waters Symmetry C_(18)) with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B) at the flow rate of 1 mL·min~(-1) and detection wavelength of 258 nm. The column temperature was 30 ℃ and the injection volume was 10 μL. The HPLC fingerprint of 24 batches of Viticis Fructus samples was established with 21 common peaks, and nine peaks were identified. Similarity analysis was carried out based on chromatographic data of 24 batches of chromatographic data of Viticis Fructus, and the results showed that except for DYMJ-16, the similarity of Vitex trifolia var. simplicifolia was ≥0.900, while that of V. trifolia was ≤0.864. In addition, the similarity analysis of two different species showed that the similarity of 16 batches of V. trifolia var. simplicifolia was 0.894-0.997 and that of the eight batches of V. trifolia was between 0.990 and 0.997. The results showed that the similarity of fingerprints of these two species was different, but the similarity between the same species was good. The results of the three multivariate statistical analyses were consistent, which could distinguish the two different species. The VIP analysis results of PLS-DA showed that casticin and agnuside contributed the most to the distinction. The content determination results showed that there was no significant difference in the content of homoorientin and p-hydroxybenzoic acid in Viticis Fructus from different species, but the content of casticin and agnuside was significantly different in different species(P<0.01). The content of casticin was higher in V. trifolia var. simplicifolia, while agnuside was higher in V. trifolia. The findings of this study show that there are differences in fingerprint similarity and component content of Viticis Fructus from different species, which can provide references for the in-depth study of the quality and clinical application of Viticis Fructus.

ABSTRACT

@#Objective     To investigate the effect of intravenous analgesia with a wireless or traditional analgesia pump system in thoracoscopic lung resection. Methods     Patients who used the patient-controlled intravenous analgesia after thoracoscopic lung resection between June 2016 and June 2021 were enrolled in the study. They were allocated into a wireless pump group (a ZigBee-based wireless analgesia pump system collecting data automatically) and a traditional analgesia pump group. Perioperative analgesia management followed the routine standard operation protocol of Shanghai Chest Hospital. The patients’ numeric rating scale (NRS) for pain and postoperative nausea and vomiting (PONV) scores were collected for analysis from the Anesthesia Information Record System. The incidence of postoperative analgesia insufficiency (defined as NRS≥4 points) within 48 h, the incidence of PONV within 24 h, and the 48 h completion rate of analgesia pump infusion were compared. Results    A total of 59 431 patients were collected, including 24 855 males and 34 576 females, 17 209 patients in the wireless pump group, and 42 222 patients in the traditional analgesia pump group. The incidence of analgesia insufficiency within 48 h after operation (3.75% vs. 4.98%, P=0.007), the incidence of PONV within 24 h after operation (13.60% vs. 16.70%, P=0.030) in the wireless pump group were lower than those in the traditional analgesia pump group. The 48 h completion rate of analgesia pump infusion in the wireless pump group was higher than that in the traditional analgesia pump group (83.40% vs. 71.90%, P<0.001). The wireless pump group could monitor the pressing times and use of the analgesia pump, while the traditional analgesia pump group could not record the relevant data. Conclusion    Compared with the traditional analgesia pump, the wireless analgesia management system may be convenient for timely, accurate and individualized management, and has good analgesic effect and low incidence of adverse reactions, and may be more suitable for perioperative analgesia management.

ABSTRACT

This article reported a male neonate with lethal mitochondrial trifunctional protein deficiency (MTPD) caused by compound heterozygous variations in the HADHB gene. The patient presented with poor milk intake complicated by abnormal myocardial enzymes within 24 h after birth and was transferred to the Children's Hospital of Nanjing Medical University on day 4. Physical examination revealed no obvious abnormalities on admission. Laboratory examination showed increased creatine kinase isoenzyme and cardiac troponin levels, and electrocardiogram suggested sinus tachycardia and low QRS voltage in limb leads. Blood screening for metabolic abnormalities showed high levels of tetradecenyl carnitine and various 3-hydroxycarnitines. Heterozygous mutations of c.739C>T(p.Arg247Cys) and c.607C>T(p.Arg203Ter,272) were detected in the HADHB gene in the boy, which were pathogenic variants included in the Human Gene Mutation Database. Followed up to three months of age, the boy was readmitted to hospital due to poor milk intake for one week and poor response for 2 d after catching a cold. After admission, he quickly developed multiple organs dysfunction such as heart failure and respiratory failure, and then died. Lethal MTPD is rare with no effective treatment and poor prognosis. Lethal MTPD should be highly suspected when unexplained cardiomyopathy, hypoglycemia, acidosis and other metabolic abnormalities appear in the neonatal period, and an early diagnosis could be confirmed with genetic testing in the neonatal period.

ABSTRACT

Objective:To investigate the counteractive effect of mouse dermal fibroblasts (MdFBs) during their adipogenic differentiation against Staphylococcus aureus infection, and to explore its mechanisms. Methods:MdFBs were obtained from newborn C57BL/6 mice, and their adipogenic differentiation was induced by culture in an adipogenic medium for 48 hours. Real-time fluorescence-based quantitative PCR (RT-PCR) was performed to determine the mRNA expression of cathelicidin antimicrobial peptide (CAMP) on days 0-6 during the adipogenic differentiation of MdFBs, and Western blot analysis to determine the protein expression of CAMP in the culture supernatant of MdFBs during their adipogenic differentiation. MdFBs were divided into 4 groups: co-stimulation group stimulated by S. aureus suspensions and cultured in an adipogenic medium, adipogenic control group cultured in an adipogenic medium, S. aureus-stimulation group stimulated by S. aureus suspensions and cultured in a common medium, and control group stimulated by phosphate-buffered saline and cultured in a common medium; Western blot analysis and RT-PCR were conducted to determine the protein and mRNA expression of CAMP. S. aureus (5 × 10 4 CFU/ml) was cultured with the culture supernatant of MdFBs after 5-day adipogenic differentiation (adipogenic group), and the growth activity was evaluated every 2 hours during 10 - 24 hours after the start of co-culture; S. aureus cultured with the culture supernatant of MdFBs in a common medium served as the normal control group, and that cultured with cell-free culture supernatant served as the negative control group. Differences between groups were assessed using unpaired t-test or analysis of variance. Results:Significant differences were observed in the relative mRNA expression of CAMP among different time points (days 0, 1, 2, 4, and 6) during the adipogenic differentiation of MdFBs (1.14 ± 0.74, 68.04 ± 12.72, 683.12 ± 38.06, 1 390.68 ± 226.21, 454.57 ± 204.12, F = 50.08, P < 0.001) ; the CAMP mRNA expression was significantly higher on days 1, 2, 4, and 6 than on day 0 ( t = 9.09, 31.03, 10.63, 3.85, respectively, all P < 0.05), and showed an initial rise and subsequent fall during days 0 - 6. The CAMP protein expression in the culture supernatant of MdFBs peaked on days 2-5 and subsequently decreased. Significant differences were observed in the mRNA and protein expression of CAMP among the control group, S. aureus-stimulation group, adipogenic control group and co-stimulation group (mRNA: 0.08 ± 0.02, 0.38 ± 0.10, 0.49 ± 0.11, 0.80 ± 0.03, respectively, F = 43.25, P < 0.05; protein: 0.433 ± 0.176, 0.574 ± 0.176, 1.007 ± 0.176, 1.217 ± 0.176, respectively, F = 46.79, P < 0.05), and the relative mRNA and protein expression of CAMP was significantly higher in the co-stimulation group than in the adipogenic control group, S. aureus-stimulation group and control group (all P < 0.05). At 10 hours during culture, the growth activity of S. aureus was significantly lower in the adipogenic group (0.053 ± 0.015) than in the normal control group and negative control group (0.109 ± 0.015, 0.106 ± 0.015, t = 11.30, 13.26, respectively, both P < 0.05) ; during 10 - 24 hours, the growth activity of S. aureus also showed a significant decrease in the adipogenic group compared with the normal control group and negative control group (all P < 0.05) . Conclusion:MdFBs secreted CAMP during the adipogenic differentiation, and could inhibit the proliferation of S. aureus.
