On the basis of the Uncaria transcriptome, specific primers were designed for UrSTR. The full-length cDNA of UrSTR (GeneBank: OL310251) was 1 541 bp, encoding 345 amino acid residues, and the promoter region sequence of UrSTR (GeneBank: OL310252) was 1 179 bp. Phylogenetic tree is revealed that UrSTR had a closest relationship with STR from Ophiorrhiza pumila and Ophiorrhiza japonica. Localization of UrSTR protein is revealed located in the vacuole membrane. Plant-care analysis indicated that the promoter region sequence of UrSTR, covering multiple light, stress and hormone-response cis-regulatory elements, and verified transcriptional activity. The results of SDS-PAGE show that pET-28a-UrSTR recombinant protein was successfully expressed, and the size was anticipated. The UrSTR prokaryotic expression system needs to be optimized in the later stage. The research lays the foundation for further purification to study its structure and functional characterization of the UrSTR protein.

Objective: To investigate the effect of rhubarb on gastrointestinal blood perfusion in critical illness and hemorrhagic shocked rats.Methods: Clinical Study: Sixty-four septic patients, who suffered from stress ulcer, were treated with rhubarb at a dose of 25 mg/kg. Twenty-five non-septic patients were taken as control. The gastrointestinal perfusion was evaluated by intramural pH (pHi). Animal study: SD rats were anesthetized with intraperitoneal sodium pentobarbital at a dose of 20 mg/kg. Blood-letting were performed in the animals. Blood pressure reduced to 5.32 kPa and maintained for 120 mins. They were resuscitated at the end of shock by reinfusing all of the shed blood. The rats were randomly divided into four groups: Normal control, shock group, therapeutic group (shocked rats were treated with 50 mg/kg rhubarb at the end of shock) and rhubarb group (normal rats were treated with rhubarb). Laser Doppler was applied to estimate the gastrointestinal blood perfusion. Results: Clinical Study: The gastrointestinal pHi in septic patients was much lower than that in the control, whereas rhubarb could obviously elevate gastrointestinal pHi (P<0.001). In addition, rhubarb also had good effect on gastric hemorrhage caused by stress ulcer. Animal Study: Although the shocked rats were resuscitated completely, their gastrointestinal blood perfusion was much lower than that in the control. Rhubarb could significantly improve the blood perfusion in gastrointestinal mucosa and mesentery (P<0.01). Furthermore, rhubarb also increase the gastrointestinal perfusion in normal rats. Conclusion: Rhubarb could improve gastrointestinal blood perfusion in critical illness and shocked rats.

Objective To screen the differentially expressed genes in esophageal squamous cell cancer (ESCC) and normal tissue of esophageal mucosa in Kazakh. Methods RNA was extracted from the ESCC sections in Kazakh patients, and was amplified to obtain cRNA. The gene expression profiles in ESCC and normal tissue of esophageal mucosa were detected by HG-U133 Plus 2.0 gene chip. The results were analyzed by bioinfor-matics. Results One hundred and seventy differentially expressed genes in ESCC and normal tissue of esophageal mucosa were found, with a difference of more than 10 times in expression levels. Of the 170 genes, 39 were up-regulated (signal log ratio > 3 ) and 131 down-regulated (signal log ratio < - 3). These factors such as cell cycle regulation, apoptosis, cytoskeleton; extracellular matrix, intracellular signal transduction, protein translation and synthesis, and immunological functions were correlated with the genes with abnormal expression. Conclusion The use of oligonucleotide microarray accurately and efficiently screen the 170 target genes in ESCC in Kazakh. It is suggested that these genes may be related to the carcinogenesis and development of ESCC in Kazakh.

In order to clarify the pharmacodynamic substances and mechanism of Xiangju Preparations (Xiangju Tablets, Xiangju Drops) in the treatment of rhinitis and sinusitis, the multi-level network integration analysis of "ingredients-targets-pathways" was conducted. 137 chemical constituents were identified in Xiangju Preparations by high pressure liquid chromatography-quadrupole-time of flight mass spectrometry (HPLC-QTOF/MS) for the first time. Network pharmacology analysis was performed on 59 potential active components. The results of network pharmacology analysis demonstrated that the medicinal ingredients in Xiangju Preparations included caffeic acid, senkyunolide F, rosmarinic acid, ligustilide, prim-O-glucosylcimifugin, linarin, magnolin, luteolin, senkyunolide I and gallic acid. These ingredients act on the crucial targets of tumor necrosis factor (TNF), interleukin 1B (IL1B), protein kinase B (AKT1), vascular endothelial growth factor A (VEGFA), signal transducer and activator of transcription 3 (STAT3) and participate in the regulation of advanced glycosylation end products-receptor of AGEs (AGE-RAGE), TNF, nuclear factor kappa B (NF-κB), and cyclic guanosine monophosphate-protein kinase G (cGMP-PKG) signaling pathways to effectively treat rhinitis and sinusitis. The excellent binding performance between above 10 active components and 5 key target proteins was further confirmed by molecular docking, indicating that these 10 ingredients are pharmacodynamic substances of Xiangju preparations. In conclusion, this study preliminarily clarified the effective components and mechanism of Xiangju preparations in the treatment of rhinitis and sinusitis, and provided a theoretical basis for the clinical application of Xiangju preparations.

The rol genes on pRiA4 plasmid of Agrobacterium rhizogenes are potent genes that promote secondary metabolism. Molecular breeding of Atropa belladonna can be conducted by introducing rol genes to increase tropane alkaloids (TAs) content in A. belladonna. In this study, the rolB gene was overexpressed in A. belladonna plants to study the effect of rolB gene on the biosynthesis of TAs. The phenotype, TAs content and expression levels of key enzyme genes in the pathway of TAs biosynthesis of transgenic A. belladonna were analyzed. The results showed that transgenic A. belladonna had developed root system, enlarged leaves, increased leaf fresh weight, deepened leaf color, enlarged flowers, changed flower shape, reduced pistil height and decreased pollen vitality. The content of TAs in the stems of transgenic A. belladonna was significantly higher than that of the control, and the contents of scopolamine, anisodamine, hyoscyamine can reach 2.11-2.91, 1.23-2.37 and 4.88-5.20 times of the control, respectively. Compared with the control group, the expressions of key enzymes putrescine N-methyltransferase (PMT), type III polyketide synthase (PYKS), tropinone reductase I (TRI), aromatic amino acid aminotransferase 4 (ArAT4), UDP-glycosyltransferase 1 (UGT1) and hyoscyamine 6-β-hydroxylase (H6H) in the TAs biosynthesis pathway were up-regulated, and the expression of tropinone reductase II (TRII) as a metabolic shunting gene was down-regulated. The results indicated that rolB gene enhanced TAs synthesis ability in roots and accumulation in stems of A. belladonna by enhancing metabolic flow of TAs synthesis pathway and weakening the metabolic shunt of competing pathway. This study laid a foundation for molecular breeding of A. belladonna with high-yield TAs content using rolB gene.

Objective: To observe the clinical efficacy of tendon-regulating and bone-setting manipulation combined with endurance resistance exercises in treating female with chronic neck pain, and explore the mechanism. Methods: A total of 57 female patients with chronic neck pain who met the inclusion criteria were randomly divided into a manipulation group (29 cases) and a medium-frequency electrotherapy group (28 cases). Patients in both groups received the same endurance exercise therapy, while those in the manipulation group received additional tendon-regulating and bone-setting manipulation, and those in the medium-frequency electrotherapy group received additional medium-frequency electrotherapy. Both groups were treated for 5 weeks. Before and after treatment, the neck function of patients was evaluated by visual analog scale (VAS), Analgesy-Meter, Northwick Park questionnaire (NPQ), root mean square (RMS) and median frequency (MF) of surface electromyography of sternocleidomastoid muscle and posterior cervical extensor muscle, and the patients were followed up at a month after treatment. Results: All patients completed the treatment and were followed up. Compared with the same group before treatment, the VAS scores of both groups decreased, the tenderness values increased, the RMS and MF values increased, and the NPQ scores decreased after treatment (all P<0.05). The improvement of manipulation group was more notable than that of medium-frequency electrotherapy group (all P<0.05). At one-month follow-up, the VAS and NPQ scores of the manipulation group were lower than those before and after treatment, and the VAS and NPQ scores of the medium-frequency electrotherapy group were only lower than those before treatment; the two scores of the manipulation group were lower than those of the medium-frequency electrotherapy group (both P<0.05). Conclusion: Tendon-regulating and bone-setting manipulation combined with endurance resistance exercises can relieve neck pain and cervical dysfunction in female patients with chronic neck pain. The efficacy of this method is more durable and better than that of medium-frequency electrotherapy combined with endurance exercises.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal disorder of hematopoiesis due to the inactivation of PIG-A gene. However, the presence of mutant PIG-A gene in a group of hematopoietic cells is not enough for the development of PNH, immunologic injury and apoptotic effects are considered to play an important role in clonal expansion. Knowledge of the molecular mechanisms leading to PNH has substantially increased in the past decades, which remarkably advances the diagnostic modalities and treatment approaches of patients with PNH. Though great progress has been made because of targeted therapy method, the challenges are still ahead. In this review the advances of studies on mechanism, laboratorial diagnosis and therapeutic protocols of PNH are summarized.
