RESUMEN
OBJECTIVE: To investigate blood pressure rhythm (BPR) in Yin deficiency syndrome of hypertension (YDSH) patients and develop a random forest model for predicting YDSH. METHODS: Our study was consistent with technical processes and specification for developing guidelines of Evidence-based Chinese medicine clinical practice (T/CACM 1032-2017). We enrolled 234 patients who had been diagnosed with primary hypertension without antihypertensive medications prior to the enrollment. All participants were divided into Yin deficiency group (YX, n = 74) and non-Yin deficiency group (NYX, n = 160). Participants were professionally grouped by three experienced chief Traditional Chinese Medicine (TCM) physicians according to four examinations (i.e., inspection, listening and smelling, inquiry and palpation). We collected data on 24 h ambulatory blood pressure monitoring (ABPM) and YDSH rating scale. We divided 24 h of a day into 12 two-hour periods [Chen-Shi (7:00-9:00), Si-Shi (9:00-11:00), Wu-Shi (11:00-13:00), Wei-Shi (13:00-15:00), Shen-Shi (15:00-17:00), You-Shi (17:00-19:00), Xu-Shi (19:00-21:00), Hai-Shi (21:00-23:00), Zi-Shi (23:00-1:00), Chou-Shi (1:00-3:00), Yin-Shi (3:00-5:00), Mao-Shi (5:00-7:00)] according to the theory of "midnight-midday ebb flow". We used random forest to build the diagnostic model of YDSH, with whether it was Yin deficiency syndrome as the outcome. RESULTS: Compared with NYX group, YX group had more female participants with older age, lower waist circumference, body mass index (BMI), diastolic blood pressure (DBP), and smoking and drinking rate (all P ï¼ 0.05). The YDSH rating scores of YX group [28.5 (21.0-36.0)] were significantly higher than NYX group [13.0 (8.0-22.0)] (P < 0.001), and the typical symptoms of YX group included vexing heat in the chest, palms and soles, dizziness, dry eyes, string-like and fine pulse, soreness and weakness of lumbus and knees, palpitations, reddened cheeks, and tinnitus (all P < 0.05). The ratio of non-dipper hypertension in YX group was higher than in NYX group (56.9% vs 44.4%, P = 0.004). Compared with NYX group, 24 h DBP standard deviation (SD), nighttime DBP SD, Si-Shi DBP, Si-Shi mean arterial pressure (MAP), Hi-Shi systolic blood pressure (SBP), Hi-Shi DBP, Hi-Shi MAP, Zi-Shi SBP, Zi-Shi DBP, Zi-Shi MAP, Chou-Shi SBP SD, Chou-Shi DBP SD, Chou-Shi SBP coefficient of variation (CV) were lower in YX group (all P ï¼ 0.05). Binary Logistic Regression analysis showed that the diagnosis of YDSH was positively correlated with age, heart rate, YDSH rating scores, and four TCM symptoms including vexing heat in the chest, palms and soles, string-like and fine pulse, soreness and weakness of lumbus and knees, and reddened cheeks (all P ï¼ 0.05), but was negatively correlated with smoking (Pï¹¥0.05). In addition, the diagnosis of YDSH was positively correlated with daytime SBP SD, nighttime SBP SD, nighttime SBP CV, and Hi-Shi SBP CV, but was negatively correlated with 24 h SBP CV, daytime DBP SD, nighttime DBP SD, and Hi-Shi DBP (all P ï¼ 0.05). Hi-Shi SBP CV had independent and positive correlation with the diagnosis of YDSH after adjusting the variables of age, gender, course of hypertension, BMI, waist circumference, SBP, DBP, heart rate, smoking and drinking (P = 0.029). Diagnostic model of YDSH was established and verified based on the random forest. The results showed that the calculation accuracy, specificity and sensitivity were 77.3%, 77.8% and 76.9%, respectively. CONCLUSION: The BPR was significantly attenuated in YDSH patients, including lower 24 h DBP SD and nighttime DBP SD, and Hi-Shi SBP CV is independently correlated with the diagnosis of YDSH. The prediction accuracy of diagnosis model of YDSH based on the random forest was good, which could be valuable for clinicians to differentiate YDSH and non-Yin deficiency patients for more effective hypertensive treatment of TCM.

This article reviews the effects of sleep deprivation during pregnancy on offspring cognition and its underlying mechanisms, in order to establish a foundation for developing scientifically sound sleep strategies during pregnancy and to provide clinical insights for improving the neurodevelopment and cognitive function of offspring.
RESUMEN
OBJECTIVE: To investigate the effects of acupotomy on the subchondral bone absorption and mechanical properties in rabbits with knee osteoarthritis (KOA). METHODS: The rabbits were divided into blank control, model, acupotomy and electroacupuncture (EA) groups, with 12 rabbits in each. Modified Videman's method was used to prepare KOA model. The acupotomy and EA group were given indicated intervention for 3 weeks. The behavior of rabbits in each group was recorded. Subsequently, cartilage-subchondral bone units were obtained and morphological changes were observed by optical microscope and micro computed tomography. Compression test was used to detect the mechanical properties of subchondral bone, Western blot and real-time polymerase chain reaction (RT-PCR) were applied to detect the expression of bone morphogenetic protein 2-Smad1 (BMP2-Smad1) pathway in subchondral bone. RESULTS: Compared with the control group, rabbits in the KOA group showed lameness, knee pain, and cartilage degradation; the subchondral bone showed active resorption, the mechanical properties decreased significantly and the BMP2-Smad1 pathway downregulated significantly. Both acupotomy and EA intervention could increase the thickness of trabecular bone (Tb. Th), the bone volume fraction (BV/TV) and the thickness of subchondral bone plate, reduce the separation of trabecular bone (Tb. Sp), improve the maximum load and elastic modulus of subchondral bone, and effectively delay cartilage degeneration in KOA rabbits. This process may be achieved through upregulation the related proteins of BMP2-Smad1 pathway. The maximum load and elastic modulus of subchondral bone in the acupotomy group were slightly better than those in the EA group. CONCLUSIONS: Acupotomy could effectively protect cartilage by inhibiting abnormal bone resorption and improving mechanical properties of subchondral bone thorough the related proteins of BMP2-Smad1 pathway in KOA rabbits.

Hispidin is an important styrylpyrone produced by Sanghuangporus sanghuang. To analyze hispidin biosynthesis in S. sanghuang, the transcriptomes of hispidin-producing and non-pro ducing S. sanghuang were determined by Illumina sequencing. Five PKSs were identified using genome annotation. Comparative analysis with the reference transcriptome showed that two PKSs (ShPKS3 and ShPKS4) had low expression levels in four types of media. The gene expression pattern of only ShPKS1 was consistent with the yield variation of hispidin. The combined analyses of gene expression with qPCR and hispidin detection by liquid chro matography-mass spectrometry coupled with ion-trap and time-of-flight technologies (LCMS-IT-TOF) showed that ShPKS1 was involved in hispidin biosynthesis in S. sanghuang.ShPKS1 is a partially reducing PKS gene with extra AMP and ACP domains before the KS domain. The domain architecture of ShPKS1 was AMP-ACP-KS-AT-DH-KR-ACP-ACP. Phylogenetic analysis shows that ShPKS1 and other PKS genes from Hymenochaetaceae form a unique monophyletic clade closely related to the clade containing Agaricales hispidin synthase. Taken together, our data indicate that ShPKS1 is a novel PKS of S. sanghuang involved in hispidin biosynthesis.

All the institutions could provide services of prevention and treatment for regular reproductive health diseases, but the numbers of institutions providing such services as nutritional assessment, common problems consultation and guidance, psycho-behavioral screening, mental health consultation and guidance, accidental injury prevention and guidance, violence injury prevention and guidance, as well as Internet addiction assessment and guidance, were 25, 20, 16, 10 and 8, respectively. There were 273 medical workers engaged in adolescent healthcare, mostly part-time (98.9%).Conclusions:The construction of outpatient clinics for adolescent health care is expected to be strengthened at health centers for women and children at district and county level in Chongqing. Meanwhile, services provision and human resources of medical workers for adolescent health care are inadequate.
RESUMEN
Objective To investigate the clinical manifestations, treatment and prognosis of primary hyperoxaluria type 1 (PH1). Methods Relevant literature review was conducted from Chongqing VIP, CNKI, Wanfang Data, PubMed, Web of Science, Embase and Cochrane databases. Clinical data of 57 patients with PH1 were collected, and the clinical manifestations, diagnosis and treatment and prognosis were analyzed. Results A total of 35 eligible studies were searched, including 57 patients with PH1, 39 male and 18 female, aged 0.2-57.0 years old, and the age of onset was from date of birth to 42 years old. The specificity of clinical symptoms of 57 patients with PH1 was relatively low, including 41 cases of renal stones, 21 cases of renal calcification and/or calcium deposition, 12 cases of oxalic acid deposition outside the urinary system, 12 cases of lumbago, backache and abdominal pain, and 8 cases of ureteral stones. Besides, alternative symptoms, such as decreased urine output, metabolic acidosis, disorder of water and electrolyte, anemia and gross hematuria were also reported. Thirty-three patients were diagnosed with end-stage renal disease (ESRD) upon admission. Twenty-six patients received transplantation. Among them, 17 cases underwent kidney transplantation (2 cases repeatedly received combined liver-kidney transplantation due to recurrence of stones and resumption of dialysis, and 1 case repeatedly received liver transplantation due to resumption of dialysis), 7 cases received combined liver-kidney transplantation, 2 cases underwent liver transplantation, and 3 cases received sequential liver-kidney transplantation, respectively. Thirty-one patients did not undergo transplantation. Significant differences were observed in the survival rate between patients treated with and without transplantation (85% vs. 58%, P < 0.05). Conclusions Clinical manifestations of PH1 are diverse and lack of specificity. A majority of PH1 patients are diagnosed with ESRD upon admission. Clinical prognosis of patients undergoing transplantation is better than that of those counterparts without transplantation. Prior liver transplantation or combined liver-kidney transplantation is recommended.
RESUMEN
Objective:To determine the protective effect of fasudil on acute lung injury in septic mice.Methods:Forty-five 4-6-week-old male C57BL mice were randomly(random number) assigned to three groups ( n=15 each group): control group, lipopolysaccharide (LPS) group and Fasudil intervention group (FAS+LPS). Acute lung injury model of septic mice was established with an intraperitoneal injection and intratracheal infusion of LPS. The mice in the FAS+LPS group were injected with fasudil hydrochloride intraperitoneally 30 min before intraperitoneal LPS injection and 1 h after intratracheal LPS infusion, respectively. All mice were sacrificed at 4 h after modeling, and lung tissues were collected. Hematoxylin-eosin staining was preformed to observe the morphological changes in the lung tissue. The wet /dry weight (W/D) ratio, malondialdehyde (MDA) content and the activity of myeloperoxidase (MPO) in the lung tissues were detected. Caspase-3 expression was examined by immunohistochemical (IHC) staining. Western blot was employed to detect the expression of RhoA, ROCK1, endothelial nitric oxide synthase (eNOS), and p-eNOS. Results:Inflammatory cell infiltration and erythrocyte exudation were significantly reduced, and the degree of interstitial oedema and derangement of alveolar structure appeared in a decreasing degree after FAS intervention. Compared with the LPS group, the W/D ratio, MDA content, MPO activity and the expression of Caspase-3 in the FAS+LPS group were significantly reduced (all P<0.01). Meanwhile, the expression of RhoA and ROCK1 of the LPS group were obviously higher than those in the control group ( P<0.05), and p-eNOS was obviously lower than that in the control group ( P<0.05). Furthermore, the expression of RhoA and ROCK1 of the FAS+LPS group were obviously lower than those in the LPS group, and p-eNOS was obviously higher than that in the LPS group. There was no significant difference on the expression of eNOS among the three groups. Conclusions:Fasudil can alleviate the degree of inflammatory cell infiltration, reduce apoptosis in lung tissue, inhibit the RhoA/ROCK1 signaling activity, and promote the phosphorylation expression of eNOS in septic mice.

RESUMEN
Extracellular vesicles (EVs), also known as membrane vesicles, are vesicular bodies secreted by eukaryotic cells and bacteria. EVs can carry proteins, DNA, RNA, and various metabolites for the exchange and transmission of substances between cells. They play contents-dependent physiological functions, such as delivering nutrients, participating in immune response, and treating cancers. Currently, most studies focus on the exploration of vesicles secreted by eukaryotic cells and gram-negative bacteria, while few studies focus on gram-positive bacteria. This review summarized the production, content composition, physiological function, and engineering of EVs secreted by gram-positive bacteria, and prospected future perspectives in this area.

Pyroptosis is a pattern of cell death to eliminate endogenous and exogenous harmful stimuli. GSDMD and GSDME, members of the Gasdermin protein family, are the main executors of pyroptosis, and after being cut by activated caspases, they can induce pyroptosis by perforating the cell membrane, and causing the release of intracellular inflammatory factors such as IL-18 and IL-1β. Recent studies have found that pyroptosis is involved and plays a "double-edged sword" role in the development and progression of liver diseases. This article elaborates on the molecular mechanism of pyroptosis and the research advances in the role of pyroptosis in the development and progression of liver diseases, so as to provide new targets and ideas for the prevention and treatment of liver diseases.
RESUMEN
BACKGROUND@#Autophagy related genes (ARGs) regulate lysosomal degradation to induce autophagy, and are involved in the occurrence and development of a variety of cancers. The expression of ARGs in tumor tissues has a great prospect in predicting the survival of patients. The aim of this study was to construct a prognostic risk score model for lung adenocarcinoma (LUAD) based on ARGs.@*METHODS@#5,786 ARGs were obtained from GeneCards database. Gene expression profiles and clinical data of 395 LUAD patients were collected from The Cancer Genome Atlas (TCGA) database. All ARGs expression data were extracted, and The ARGs differentially expressed were identified by R software. Survival analysis of differentially expressed ARGs was performed to screen for ARGs with prognostic value, and functional enrichment analysis was performed. The least absolute selection operator (LASSO) regression and Cox regression model were used to construct a prognostic risk scoring model for ARGs. The receiver operating characteristic (ROC) curve was drawn to obtain the optimal cut-off value of risk score. According to the cut-off value, the patients were divided into high-risk group and low-risk group. The area under curve (AUC) and the Kaplan-Meier survival curve was plotted to evaluate the model performance, which was verified in external data sets. Finally, univariate and multivariate Cox regression analysis was applied to evaluate the independent prognostic value of the model, and its clinical relevance was analyzed.@*RESULTS@#Survival analysis, Lasso regression and Cox regression analysis were used to construct a LUAD prognostic risk score model with five ARGs (ADAM12, CAMP, DKK1, STRIP2 and TFAP2A). The survival time of patients with low-risk score in this model was significantly better than that of patients with high-risk score (P<0.001). The model showed good prediction performance for LUAD in both the training set (AUCmax=0.78) and two external validation sets (AUCmax=0.88). Risk score was significantly associated with the prognosis of LUAD patients in univariate and multivariate Cox regression analyses, suggested that risk score could be a potential independent prognostic factor for LUAD. Correlation analysis of clinical characteristic showed that high risk score was closely associated with high T stage, high tumor stage and poor prognosis.@*CONCLUSIONS@#We constructed a LUAD risk score model consisting of five ARGs, which can provide a reference for predicting the prognosis of LUAD patients, and may be used in combination with tumor node metastasis (TNM) staging for prognosis prediction of LUAD patients in the future.
RESUMEN
Objective:The aim of this study was to investigate the carrier ratio and the genotype of thalassemia among Tujia and Miao people of reproductive age in Chongqing.Methods:According to forward-looking design and multi-stage stratified cluster sampling method, fasting venous blood samples of Tujia and Miao people of reproductive age were collected from 11 survey sites in Chongqing from March to July 2019. Gap-PCR and high-throughput sequencing were used to screen thalassemia genes.Results:A total of 516 Tujia people (258 males, 258 females) and 270 Miao people (139 males, 131 females) were included in this study, and their age were (28.63 ± 5.26) and (28.62 ± 5.35) years, respectively. About 5.04% (26/516) Tujia people carried thalassemia gene, with 1.94% (10/516) and 2.52% (13/516) for α and β thalassemia, respectively. Three kinds of new variants (1 case of each variant), HBA 2: c.46G>A (Gly>Ser), HBB: c.*+129T>A and HBB: c.-39T>G with unclear pathogenicity, were identified in Tujia people. About 7.78% (21/270) Miao people carried thalassemia gene, among these, α and β thalassemia were 3.33% (9/270) and 4.44%(12/270), respectively. The most common mutation type of α-globin gene was -α 3.7/in the two ethnic groups. Three kinds of β-globin gene mutation types, Codons 41/42 (-TTCT) beta 0, Codon 17 (A>T) beta 0 and IVS-Ⅱ-654 (C>T) beta +, were the most common in Tujia people. Meanwhile, the chief β-globin gene mutation type was Codons 41/42 (-TTCT) beta 0 in Miao people. Conclusions:The carrying rate of thalassemia gene is higher in Tujia and Miao people in Chongqing, and the genotypes of thalassemia gene are different between Tujia and Miao people. The clinical significance of three kinds of new variants with unclear pathogenicity should be focused on.
RESUMEN
Circulating tumor DNAs (ctDNAs) are DNA fragments released from tumor cells into bloodstream, containing genetic mutations and epigenetic variations related to cancer. DNA methylation variation is a kind of epigenetic variation which happens in early carcinogenesis and dynamically changes with cancer development. Liquid biopsy of ctDNA methylation has the advantages of non-invasiveness, target molecule stableness, considerable cost-effectiveness, high diagnostic performance and wide application expansion, detection of whose level is conducive to early diagnosis and prognostic evaluation of cancer. The pre-analytical procedures and methylation detection methodologies significantly influence after test results, and should be standardized to obtain high quality results. Up to now, a large amount of literature covering the utility of ctDNA methylation in cancer diagnosis and prognosis have been published. It is believed that in the near future, the detection process of ctDNA methylation would be standardized, and the large-scale clinical application of ctDNA methylation as a liquid biopsy project would be promoted.
RESUMEN
There are a wide range of gap junction proteins and pannexins between brain cells. The neurovascular unit, which are composed of neurons, glial cells and vascular cells, integrate and process information through cell membrane channels composed of gap junction proteins and pannexins, so as to maintain the dynamic balance of the nervous system. After cerebral ischemia, cell membrane channels play an important role in ischemic brain injury by participating in excitatory toxicity, inflammatory response, blood-brain barrier injury and other pathological mechanisms. Therefore, maintaining the normal function of gap junction proteins and pannnexins is essential to protect neurons from ischemic brain injury.

Objective:To evaluate the effect of fascia iliaca compartment block (FICB) on postoperative delirium in elderly patients undergoing total hip arthroplasty (THA).Methods:One hundred and two patients of both sexes, aged ≥ 65 yr, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with body mass index ≤ 35 kg/m 2, undergoing elective THA under combined spinal-epidural anesthesia, were divided into 2 groups ( n=51 each) using a random number table method: FICB group and patient-controlled intravenous analgesia (PCIA) group.In group FICB, FICB was performed under ultrasound guidance after operation, 0.5% ropivacaine 30 ml (a loading dose) was given after successful insertion of the catheter, then the analgesic pump was connected, the analgesia solution contained 0.25% ropivacaine in 275 ml of normal saline, and the pump was set up with a 0.5 ml bolus dose, a 15 min lockout interval and background infusion at a rate of 5 ml/h.In group PCIA, the PCIA solution contained fentanyl 10 μg/ml in 100 ml of normal saline, and the pump was set up with a 1 ml bolus dose, a 10 min lockout interval and background infusion at a rate of 2 ml/h.Analgesia was maintained until 48 h after operation, and the visual analogue scale (VAS) score was maintained ≤4 in the two groups.When the VAS score was >4, the analgesic pump was pressed first followed by 10-20 min of observation.When the VAS score was still >4, flurbiprofen axetil 50 mg was intravenously injected for rescue analgesia.The Confusion Assessment Method was used to assess the development of delirium within 48 h after operation.The requirement for rescue analgesia and development of nausea and vomiting, urinary retention, constipation and pruritus were recorded within 48 h after operation.The serum concentrations of interleukin-6 (IL-6), IL-8, tumor necrosis factor-alpha and S100β protein were measured at 24 h before operation and 24 and 48 h after operation. Results:Compared with group PCIA, the incidence of postoperative delirium was significantly decreased after operation, the serum concentration of S100β protein was decreased at 24 and 48 h after operation ( P<0.05), and no significant change was found in the requirement for rescue analgesia, incidence of nausea and vomiting, urinary retention, constipation and pruritus after operation, and serum concentrations of IL-6, IL-8 and tumor necrosis factor-alpha at each time point in group FICB ( P>0.05). Conclusion:FICB can reduce the development of postoperative delirium in elderly patients undergoing THA.
RESUMEN
BACKGROUND: EGFR mutational testing is crucial for advanced non-squamous NSCLC. PAP is a sensitive and selective method to detect rare mutations. METHODS: Eighty-five patients with non-squamous NSCLC were enrolled in this study. A set of paired plasma samples from each patient were collected and detected by PAP and ARMS. RESULTS: Of 85 paired samples, 78.8% (67/85) presented the same mutational status by the two methods. There was no statistically significant difference between the mutation frequencies in plasma samples detected with PAP and ARMS (p = 0.096). CONCLUSIONS: PAP technology appears to be an alternative choice with relatively high sensitivity for the detection of plasma EGFR mutations.

PURPOSE: This study was aimed to investigate the role of poly(A)-binding protein-interacting protein 1 (Paip1) in cervical carcinogenesis. MATERIALS AND METHODS: The expression of Paip1 in normal cervical epithelial tissues and cervical cancer (CC) tissues were detected by immunohistochemistry. In vivo and in vitro assays were performed to validate effect of Paip1 on CC progression. RESULTS: Paip1 was found to be up-regulated in CC, which was linked with shorter survival. Knockdown of Paip1 inhibited cell growth, induced apoptosis and cell cycle arrest in CC cells, whereas its overexpression reversed these effects. The in vivo tumor model confirmed the pro-tumor role of Paip1 in CC growth. CONCLUSION: Altogether, the investigation demonstrated the clinical significance of Paip1 expression, which prompted that the up-regulated of Paip1 can presumably be a potential prognostic and progression marker for CC.
