ABSTRACT
Background/Aims@#Stigma related with antidepressants is prevalent in patients with functional dyspepsia. It affects medication compliance and efficacy.Herbal medicine acquired a deep-rooted cultural identity in relieving dyspeptic symptoms in Asians. The research was designed to compare the effectiveness of Zhizhu Kuanzhong capsules (ZZKZ) versus doxepin hydrochloride (doxepin) on alleviating stigma and medication nonadherence among patients with refractory FD (rFD). @*Methods@#Patients with rFD from February 2021 to February 2022 were randomly allocated to receive either doxepin (n = 56) or ZZKZ (n = 57) combined with omeprazole for 4 weeks. Medication possession ratio (MPR), the disease- and medication-associated stigma were analyzed. The scales were utilized to assess dyspeptic symptoms (Leeds Dyspepsia Questionnaire) and psychological conditions (Generalized Anxiety Disorder Questionnaire and Patient Health Questionnaire). @*Results@#The MPR values for ZZKZ were significantly higher than those for doxepin (P < 0.001). The stigma scores decreased in ZZKZ group while increased in doxepin group compared to baseline after treatment. The proportion of patients showing ZZKZ-associated stigma was significantly lower than doxepin-associated stigma (P < 0.001). The MPR values were negatively correlated with posttreatment stigma scores in both groups (P < 0.001). Dyspeptic symptoms and psychological condition were improved in both groups after treatment, with no significant difference on post-treatment Leeds Dyspepsia Questionnaire, Generalized Anxiety Disorder Questionnaire, or Patient Health Questionnaire scores between 2 groups. @*Conclusion@#ZZKZ is superior to doxepin in alleviating stigma and medication non-adherence, with comparable efficacy in improving dyspeptic symptoms and psychological condition of patients with rFD.

To reveal the extra- and intramuscular nerve distribution patterns of the gluteus maximus, medius, and minimus, and to provide guidance for gluteal muscle injection in order to avoid nerve injury. Ten adult and 10 child cadavers were used. The superior and inferior gluteal nerves innervating the gluteus maximus, medius, and minimus were dissected, exposed, and sutured in-situ on the muscle. The three gluteal muscles were removed, and the distribution patterns of the intramuscular nerves were revealed by modified Sihler's nerve staining. The nerve distribution pattern was returned to the corresponding position in the body, and the patterns in the four quadrants of the buttock were analyzed. There were 3-12 extramuscular nerve branches of the gluteus maximus, medius, and minimus. After entering the muscle, these nerve branches arborized and anastomosed to form an arc-shaped, nerve-dense zone. The nerve distribution was most dense in the inferomedial region of the superolateral quadrant and the inferolateral region of the superomedial quadrant of the buttocks. The nerve distribution was relatively dense in the inferolateral region of the superolateral quadrant, and the medial region of the inferomedial quadrant. An arc-shaped, nerve-sparse zone in the superolateral and superomedial quadrants near the lower iliac crest accounted for about two-fifths of the two quadrants' limits. The arc-shaped, nerve-sparse zone in the superolateral quadrant is the preferred injection site, and the superomedial quadrant near the lower iliac crest is also recommended as a gluteal intramuscular injection region, free from nerve injury.
El objetivo de este trabajo fue revelar los patrones de distribución nerviosa extramusculat e intramuscular de los músculos glúteo máximo, medio y mínimo y proporcionar orientación para la inyección en la región glútea con el propósito de evitar lesiones nerviosas. Se utilizaron diez cadáveres adultos y diez niños. Los nervios glúteos superior e inferior que inervan a los músculos glúteo máximo, medio y mínimo fueron disecados, expuestos y suturados in situ en el músculo. Se extirparon los tres músculos glúteos y se revelaron los patrones de distribución de los nervios intramusculares mediante la tinción nerviosa de Sihler modificada. El patrón de distribución nerviosa se devolvió a la posición correspondiente en el cuerpo y se analizaron los patrones en los cuatro cuadrantes de la región glútea. Se encontraron 3 a 12 ramos nerviosos extramusculares de los músculos glúteo máximo, medio y mínimo. Después de ingresar al músculo, estas ramas nerviosas se arborizaron y anastomizaron para formar una zona densamente nerviosa en forma de arco. La distribución nerviosa fue de mayor densidad en la región inferomedial del cuadrante superolateral y en la región inferolateral del cuadrante superomedial de la región glútea. La distribución nerviosa era relativamente densa en la región inferolateral del cuadrante superolateral y en la región medial del cuadrante inferomedial. Una zona en forma de arco en los cuadrantes superolateral y superomedial y con escasa inervación, cerca de la cresta ilíaca representaba una parte de los límites de los dos cuadrantes. La zona de poca inervación en forma de arco en el cuadrante superolateral es el sitio de inyección preferido, y el cuadrante superomedial próximo a la cresta ilíaca también se recomienda como una región de inyección intramuscular glútea, libre de lesión nerviosa.

Hyperglycemia is the dominant phenotype of diabetes and the main contributor of diabetic complications. Puerarin is widely used in cardiovascular diseases and diabetic vascular complications. However, little is known about its direct effects on diabetes. The aim of our study is to investigate its antidiabetic effect in vivo and in vitro, and explore the underlying mechanism. We used type I diabetic mice induced by streptozotocin to observe the effects of puerarin on glucose metabolism. In addition, oxidative stress and hepatic mitochondrial respiratory activity were evaluated in type I diabetic mice. In vitro, glucose consumption in HepG2 cells was assayed along with the qPCR detection of glucogenesis genes expression. Moreover, ATP production was examined and phosphorylation of AMPK was determined using Western blot. Finally, the molecular docking was performed to predict the potential interaction of puerarin with AMPK utilizing program LibDock of Discovery Studio 2018 software. The results showed that puerarin improved HepG2 glucose consumption and upregulated the glucogenesis related genes expression. Also, puerarin lowered fasting and fed blood glucose with improvement of glucose tolerance in type I diabetic mice. Further mechanism investigation showed that puerarin suppressed oxidative stress and improved hepatic mitochondrial respiratory function with enhancing ATP production and activating phosphorylation of AMPK. Docking study showed that puerarin interacted with AMPK activate site and enhancing phosphorylation. Taken together, these findings indicated that puerarin exhibited the hypoglycemic effect through attenuating oxidative stress and improving mitochondrial function via AMPK regulation, which may serve as a potential therapeutic option for diabetes treatment.
ABSTRACT
Excess accumulation of white adipose tissue (WAT) causes obesity which is an imbalance between energy intake and energy expenditure. Obesity is a serious concern because it has been the leading causes of death worldwide, including diabetes, stroke, heart disease and cancer. Therefore, uncovering the mechanism of obesity and discovering anti-obesity drugs are crucial to prevent obesity and its complications. Browning, inducing white adipose tissue to brown or beige (brite) fat which is brown-like fat emerging in WAT, becomes an appealing therapeutic strategy for obesity and metabolic disorders. Due to lack of efficacy or intolerable side-effects, the clinical trials that promote brown adipose tissue (BAT) thermogenesis and browning of WAT have not been successful in humans. Obviously, more specific means still need to be developed to activate browning of white adipose tissue. In this review, we summarized seven kinds of natural products (alkaloids, flavonoids, terpenoids, long chain fatty acids, phenolic acids, else and extract) promoting white adipose tissue browning which can ameliorate the metabolic disorders, including obesity, dislipidemia, insulin resistance and diabetes. Since natural products are important drug sources and the browning property plays a significant role in not only obesity treatment but also in type 2 diabetes (T2DM) improvement, natural products of inducing browning may be an irreplaceable drug discovery orientation for obesity, diabetes and even other metabolic disorders.
ABSTRACT
Cardiopulmonary bypass (CPB) is often accompanied by postoperative nerve injury in children. Studies have shown that monitoring of cerebral blood flow and cerebral oxygenation during enhanced operation can help to detect the adverse events of cerebral ischemia and hypoxia in time, guide physicians to adjust perfusion parameters in time, and can significantly reduce the incidence of postoperative nerve injury and improve the prognosis of children. Transcranial doppler (TCD) can directly reflect cerebral perfusion and indirectly reflect cerebral oxygen supply and demand by monitoring cerebral blood flow velocity, and jugular blood oxygen saturation (SjbO2) and cerebral local oxygen saturation (CrSO2) directly reflect cerebral oxygen supply and demand by monitoring cerebral oxygenation in the cerebral hemisphere. Therefore, the combined monitoring of these indexes during the perioperative period of cardiac surgery in children can reflect the cerebral oxygen supply and demand in an all-round way, and prevent the ischemic and hypoxic nerve injury. The research status has been reviewed in present paper of TCD, SjbO2 and CrSO2 in monitoring cerebral oxygen supply and demand during perioperative cardiac surgery in children with CPB in order to provide evidence for the prevention of postoperative nerve injury.
ABSTRACT
This study aimed to analyze the clinical phenotype of chromosome 9p deletion or duplication and its relationship with karyotype. A patient, female, aged 6 months, visited the hospital due to motor developmental delay. Karyotype analysis identified abnormalities of chromosome 9 short arm, and high-throughput sequencing found 9p24.3-9p23 deletion and 9p23-9p13.1 duplication. Her parents had a normal karyotype. Karyotype analysis combined with high-throughput sequencing is of great significance for improving the efficiency of etiological diagnosis in children with motor developmental delay or multiple congenital deformities and mental retardation.
ABSTRACT
OBJECTIVE Diabetic nephropathy (DN) has been one of the most common complications of diabetes and the leading cause of end-stage renal disease. Glomerular hyperfiltrationis central in earlystage of DN and leads to the progression of renal architectonic and functional abnormalities. Salvi?anolic acid A (SalA) has been proved to protect diabetic complications such as hepatic fibrosis and neuropathy. The present study was designed to investigate the effects of SalAon glomerular endothelial dysfunctionand diabetic nephropathy. METHODS Primary glomerular endothelial cells were subjected to assess permeability under injury of advanced glycation end-products (AGEs). AGEs-induced changes of RhoA/ROCK pathway and cytoskeleton rearrangement were assessed bywestern blotandimmunoflu?orescence. The beneficial effects of SalA on diabetic nephropathy were investigated in a rat model induced by high-fat and high-glucose diet combined with low dose of streptozocin (35 mg·kg- 1, ip). Renal function and architectonic changes were evaluated by biochemical assay and PAS staining. RESULTS SalA 3μMameliorated AGEs- induced glomerular endothelial permeability (P<0.05) and suppressed rearrangement of cytoskeleton through inhibiting AGE-RAGE-RhoA/ROCK pathway. SalA 1 mg · kg- 1 markedly reduced endothelium loss (P<0.01) and glomerular hyperfiltration (P<0.05) in diabetic kidney. Subsequently,SalA 1 mg·kg-1 suppressed glomerular hypertrophy and mesangial matrix expansion, eventually reduced 24 h-urinary albumin and ameliorated renal function by decreasing blood urine nitrogen (BUN), serum creatinine (Scr) and serum n-acetyl-β-d-glucosaminidase (NAG). AGEs-RAGE-Nox4-induced oxidative stress was suppressed by the treatment of SalA 1 mg·kg-1. CONCLUSION SalA ameliorated AGEs-induced glomerular endothelial hyperpermeability, and effec?tively protected against early-stage diabetic nephropathy by reducing hyperfiltration and alleviating renal structural deterioration through inhibiting AGEs and its downstream pathway. Thus, SalA might be a promising therapeutic agent for the treatment of diabetic nephropathy.
ABSTRACT
Objective To compare biomechanical performance of four-part proximal humeral fractures fixed by novel locking plate or by AO-PHILOS plate. Methods The finite element fixation models of both the novel locking plate and AO-PHILOS plate for four-part proximal humeral fractures were established, respectively. The maximum Von Mises stress and displacement under 4 different functional positions of shoulder abduction in the two fixation models were compared by finite element analysis. Results The maximum displacement in shoulder abduction of 0°,30°,60°,90° were 6.644, 7.079, 5.850, 3.005 mm, respectively, in novel locking plate fixation model, and 6.293, 6.826, 5.774, 3.023 mm, respectively, in AO-PHILOS plate fixation model. Since the maximum displacements in both fracture fixation models were similar, it indicated that there was no significant difference in the stability for fixing proximal humeral fracture. The maximum Von Mises stress in shoulder abduction of 0°,30°,60°,90°were 1 033.0, 904.1, 888.1, 1 062.0 MPa in novel locking plate fixation model, while in AO-PHILOS plate fixation model, it showed 743.1, 692.4,486.4,393.5 MPa, respectively. During the process of shoulder abduction, the total stress in both fracture fixation models gradually decreased, but the new locking plate decreased in a larger range, showing an obvious stress dispersion. Conclusions Both the novel locking plate and AO-PHILOS plate can be used as internal fixation treatment for complex four-part proximal humeral fractures with no significant difference in stress distribution, and both showing a stable fixation effect. For fixing proximal humeral fractures with osteoporosis combined with the great and less tuberosity, the novel locking plate has an advantage over AO-PHILOS plate due to its unique anatomical wings and better fixing effect.
ABSTRACT
Diabetic nephropathy presents an increasing trend worldwide. It has been an attractive area to find novel targets for the treatment of diabetic nephropathy. SIRT1 (Sirtuin 1), a member of deacetylation enzymes, regulates cell senescence, metabolism, and apoptosis. In last ten years, lots of studies showed that SIRT1 exerts a protective effect in the progression of the diabetic nephropathy by promoting reconstruction of energy homeostasis, modulating cell redox state, resisting cell apoptosis, inhibiting inflammation and ameliorating renal fibrosis. SIRT1 has become a potential new target for the treatment of diabetic nephropathy.

Late embryogenesis abundant (LEA) protein family is a large protein family that includes proteins accumulated at late stages of seed development or in vegetative tissues in response to drought, salinity, cold stress and exogenous application of abscisic acid. In order to isolate peanut genes, an expressed sequence tag (EST) sequencing project was carried out using a peanut seed cDNA library. From 6258 ESTs, 19 LEA-encoding genes were identified and could be classified into eight distinct groups. Expression of these genes in seeds at different developmental stages and in various peanut tissues was analysed by semi-quantitative RT-PCR. The results showed that expression levels of LEA genes were generally high in seeds. Some LEA protein genes were expressed at a high level in non-seed tissues such as root, stem, leaf, flower and gynophore. These results provided valuable information for the functional and regulatory studies on peanut LEA genes.
ABSTRACT
<p><b>BACKGROUND</b>The neurogenic bladder dysfunction caused by spinal cord injury is difficult to treat clinically. The aim of this research was to establish an artificial bladder reflex arc in rats through abdominal reflex pathway above the level of spinal cord injury, reinnervate the neurogenic bladder and restore bladder micturition.</p><p><b>METHODS</b>The outcome was achieved by intradural microanastomosis of the right T13 ventral root to S2 ventral root with autogenous nerve grafting, leaving the right T13 dorsal root intact. Long-term function of the reflex arc was assessed from nerve electrophysiological data and intravesical pressure tests during 8 months postoperation. Horseradish peroxidase (HRP) tracing was performed to observe the effectiveness of the artificial reflex.</p><p><b>RESULTS</b>Single stimulus (3 mA, 0.3 ms pulses, 20 Hz, 5-second duration) on the right T13 dorsal root resulted in evoked action potentials, raised intravesical pressures and bladder smooth muscle, compound action potential recorded from the right vesical plexus before and after the spinal cord transaction injury between L5 and S4 segmental in 12 Sprague-Dawley rats. There were HRP labelled cells in T13 ventral horn on the experimental side and in the intermediolateral nucleus on both sides of the L6-S4 segments after HRP injection. There was no HRP labelled cell in T13 ventral horn on the control side.</p><p><b>CONCLUSION</b>Using the surviving somatic reflex above the level of spinal cord injury to reconstruct the bladder autonomous reflex arc by intradural microanastomosis of ventral root with a segment of autologous nerve grafting is practical in rats and may have clinical applications for humans.</p>

Microsatellites, or simple sequence repeats (SSRs), in expressed sequence tags (ESTs) provide an opportunity for low cost SSR development. We looked for EST-SSRs in 403,511 ESTs (generated by 454 sequencing and representing 70,654 contigs and 52,082 singletons) from soybean globular stage embryos. Among 122,736 unique ESTs, 3,729 contained one or more SSRs. In total, 3,989 SSRs were identified including 304 mono, 1,374 di, 2,208 tri, 70 tetra, 13 penta and 20 hexanucleotide SSRs. Thirty three EST-SSRs were selected for primer design and polymorphism analysis using twenty soybean cultivars and one wild-type soybean. Successful amplification was obtained using 21 of these primer pairs, 11 of which detected polymorphisms in these soybean cultivars. These results demonstrated that 454 high throughput sequencing is a powerful tool for molecular marker development. From the 3,989 identified SSRs we expect to obtain a large number of makers with polymorphism among different soybean cultivars, which would be useful for analysis of genetic diversity and maker assisted selection in the soybean breeding programs.

Making use of the gene resources of wild type peanuts is a way to increase the genetic diversity of the cultivars. Marker assisted selection (MAS) could shorten the process of inter-specific hybridization and provide a possible way to remove the undesirable traits. However, the limited number of molecular markers available in peanut retarded its MAS process. We started a peanut ESTs (Expressed Sequence Tags) project aiming at cloning genes with agronomic importance and developing molecular markers. In this study we found 610 ESTs that contained one or more SSRs from 12,000 peanut ESTs. The most abundant SSRs in peanut are trinucleotides (66.3 percent) SSRs and followed by dinucleotide (28.8 percent) SSRs. AG/TC (10.7 percent) repeat was the most abundant and followed by CT/GA (9.0 percent), CTT/GAA (7.4 percent), and AAG/TTC (7.3 percent) repeats. Ninety-four SSR containing ESTs were randomly selected for primer design and synthesis, of which 33 pairs could generate good amplification and were used for polymorphism assessment. Results showed that polymorphism was very low in cultivars, while high level of polymorphism was revealed in wild type peanuts.

The cultivated peanut is a valuable source of dietary oil and ranks fi fth among the world oil crops. Plant fatty acid biosynthesis is catalysed by type II fatty acid synthase (FAS) in plastids and mitochondria. By constructing a full-length cDNA library derived from immature peanut seeds and homology-based cloning, candidate genes of acyl carrier protein (ACP), malonyl-CoA:ACP transacylase, β-ketoacyl-ACP synthase (I, II, III), β-ketoacyl-ACP reductase, β-hydroxyacyl-ACP dehydrase and enoyl-ACP reductase were isolated. Sequence alignments revealed that primary structures of type II FAS enzymes were highly conserved in higher plants and the catalytic residues were strictly conserved in Escherichia coli and higher plants. Homologue numbers of each type II FAS gene expressing in developing peanut seeds varied from 1 in KASII, KASIII and HD to 5 in ENR. The number of single-nucleotide polymorphisms (SNPs) was quite different in each gene. Peanut type II FAS genes were predicted to target plastids except ACP2 and ACP3. The results suggested that peanut may contain two type II FAS systems in plastids and mitochondria. The type II FAS enzymes in higher plants may have similar functions as those in E. coli.
ABSTRACT
The effect of curcumin on JAK-STAT signaling pathway was investigated in hepatoma cell lines Huh7 and Hep3B. Curcumin inhibited cell proliferation and induced apoptosis of both cell lines, but Huh7 cells were more sensitive to curcumin than Hep3B cells. Curcumin (50 micromol x L(-1)) significantly increased phosphorylations of p38 (T180/Y182) and STAT-1 (S727) in Huh7 and Hep3B cells, and caused relocalization of phosphorylated-STAT-1 (Y701) from cytoplasm to nucleus in Hep3B cells. In addition, curcumin (25 and 50 micromol x L(-1)) dramatically suppressed the phosphorylation level of STAT-1 (Y701) and resulted in a significant reduction of nuclear phosphorylated-STAT-1 (Y701) in Huh7 cells.

In the present study, shRNA plasmid of pSi-p21 targeting p21 mRNA was constructed and the effect of p21 shRNA on curcumin-induced apoptosis of human hepatoma Huh7 cells was investigated. The effect of curcumin on the expression of p21 mRNA and protein and the silence efficiency of pSi-p21 were detected with RT-PCR and Western blotting. The effect of pSi-p21 on curcumin-induced apoptosis of Huh7 cells was evaluated with DAPI staining. The results showed that curcumin significantly upregulated p21 mRNA and protein expression, which was knocked down by pSi-p21 of Huh7 cells. DAPI staining results showed that pSi-p21 significantly decreased curcumin-induced apoptosis of Huh7 cells. The data suggested that curcumin induced apoptosis of Huh7 cells via upregulation of p21 expression.
