SUN Shen-tian's clinical experience in treating Tourette's syndrome with acupuncture / 中国针灸

To introduce the clinical experience of professor SUN Shen-tian in treatment of Tourette's syndrome (TS) with acupuncture. TS is a psychosomatic disease and the core pathogenesis refers to blood deficiency producing internal wind. The disease is located in the heart and liver. Acupoints are selected according to the functional orientation of the cerebral cortex. The extrapyramidal system area is preferred for tic disorder, and the emotional area is for behavioral disorder. The treatment focuses on regulating the mind by multiple methods, including manual needling technique used the transcranial repeated acupuncture, and regulating the mind by taking multiple acupoints, Baihui (GV 20), Neiguan (PC 6), Shenmen (HT 7) and Dazhong (KI 4) are stimulated. For abdominal twitching and mental symptoms of TS children, the first and third abdominal areas are selected. The target symptoms (biao) are treated specially by local acupoints, the combination of the starting and ending acupoints of the affected meridian, or the acupoints of the meridians with same name. The modified chaihu longgu muli decoction and siwu decoction are prescribed to sooth liver, nourish blood and soothe wind. In association with the characteristics and target symptoms of TS, the sequential therapy is used with filiform needling, intradermal needling, Chinese herbal medication and psychotherapy.

Full-length transcriptome sequence and identification of genes involved in phenylethanol glycoside biosynthesis in Rehmannia glutinosa / 药学学报

italic>Rehmannia glutinosa belongs to the Scrophulariaceae family with important medicinal value. In order to effectively explore the transcriptome information of R. glutinosa and identify the genes encoding enzymes involved in phenylethanol glycoside (PhGs) biosynthesis, the leaves, stems and tuberous roots of R. glutinosa were used for transcriptome sequencing using Pacific Biosiences RS II platform. A total of 27 773 transcripts were generated with an average length of 2 380 bp, and 27 236 coding sequences (CDS) were predicted. Using BLAST software, non-redundant transcript sequences were annotated with NR, NT, GO, COG, KEGG, SwissProt and Interpro databases and a total of 27 399 annotated genes were obtained. Among them, the number of genes related to Sesamum indicum in the NR database was the highest (81.44%), which is consistent with their evolutionary relationship. Enzymes likely involved in the biosynthesis of isoacteoside, echinacoside, cistanosides A, cistanosides F, 2′-acetylacteoside and leonoside F were identified, and 143 genes were identified in R. glutinosa full-length transcriptome. The expression levels of 19 genes correlated with acteoside content in twelve tissues of R. glutinosa, and most showed higher expression levels in leaf tissues and floral organs. This study provides more reliable transcriptome data for screening R. glutinosa for functional genes and provides a foundation for the study of the molecular mechanisms of PhGs biosynthesis.

Effect of Placing Drainage or Not on Rapid Rehabilitation after Primary Total Knee Arthroplasty / 中国康复理论与实践

Objective:To explore the effect of placing drainage or not on rapid rehabilitation after total knee arthroplasty (TKA). Methods:From January, 2018 to September, 2020, 80 patients with knee osteoarthritis who underwent primary TKA in our hospital were analyzed retrospectively, and they were divided into groups A and B, with 40 cases in each group. Drainage was placed routinely in group A and not in group B. The postoperative serum inflammatory factors, postoperative pain score, postoperative complication rate, postoperative time out of bed, hospital stay, knee function score, range of motion of knee and World Health Organization Quality Of Life-abbreviated version score (WHOQOL-BREF) were compared between two groups. Results:There was no significant difference in the levels of C-reactive protein between two groups on the 1st to 3rd day after operation (t < 0.410, P > 0.05). There was no significant difference in Visual Analogue Score between two groups from 12 h to 48 h after operation (t < 0.300, P > 0.05). The incidences of postoperative complications were 5.0% in group A and 2.5% in group B, with no significant difference between two groups (χ2 = 0.346, P > 0.05). The time of getting out of bed and hospital stay was significantly shorter in group B than in group A (t > 4.863, P < 0.001). The scores of knee joint function, range of motion of knee and WHOQOL-BREF significantly increased after operation in both groups (t > 6.099, P < 0.001), however, there was no significant difference between two groups (P > 0.05). Conclusion:Placement or non-placement of drainage after primary TKA does not affect postoperative complications, knee joint function and quality of life of patients with knee osteoarthritis, however, non-placement of drainage can promote postoperative recovery and discharge.

Effects of vitamin C on function of different subtypes of glycine receptors / 中国药理学通报

Aim To investigate the effects of vitamin C (VC) on glycine receptor (GlyR) subtypes. Methods The HEK-293T cells were transfected with plasmids expressing different subtypes of GlyR. Then the cells were incubated with different concentrations of VC. The EC2 concentration of glycine-activated currents were recorded by patch clamp before or after incubation of VC. The effects of the sodium-dependent vitamin C transporter-type 2 ( SVCT2 ) inhibitor sulfinpyrazone on VC induced potentiation of GlyRs were also examined. The method of amino acid point mutation was used to explore the critical site for interaction between VC and GlyR. Results Ascorbic acid dose-dependently increased the currents mediated by GlyRal and GlyRa3, with a3 subunits being the most sensitive to VC. Ascorbic acid had no significant effect on the current mediated by the al subunit of GlyRs. Cell incubation with sulfinpyrazone did not affect the VC induced potentiation of GlyR function. The mutation of Ser296 at the third transmembrane domain of a3 GlyR significantly reduced the potentiation of VC on GlyR func-tion. Conclusions Ascorbic acid can enhance the function of GlyR al and a3 subunits, but not a2 sub- unit. Such enhancement is not likely to be an effect oc- curing inside cells. The Ser296 of GlyR plays a key role in the VC induced enhancement of GlyR function.

Effects of density on growth and gene transcription characteristics of Rehmannia glutinosa / 中国中药杂志

The present study analyzed the effects of planting density on the development, quality, and gene transcription characte-ristics of Rehmannia glutinosa using 85-5 and J9 as materials with three planting densities of 5 000, 25 000, and 50 000 plants/Mu(1 Mu≈667 m~2). The agronomic characteristics of leaves and tuberous roots, the content of catalpol and acteoside, and the changes of gene expression were determined. The results showed that the leaf size, the diameter of tuberous root, leaf biomass, tuberous root number, and tuberous root biomass per plant at low density were significantly higher than those of medium and high densities. The content of catalpol and acteoside in leaves was higher at high density. The content of catalpol in tuberous roots was higher at low density, and the change trend was similar to that in leaves, while the content of acteoside in tuberous roots was higher at high density. Transcriptome analysis found that about 1/2 of the expansin genes could change regularly in response to density treatment, which was rela-ted to the development of tuberous roots. The change trend of the gene expression of multiple catalytic enzymes involved in the biosynthesis of catalpol and acteoside was consistent with that of their content, which was presumedly involved in the accumulation and regulation of density-responsive medicinal components. Based on the analysis of the development, medicinal components, and gene expression characteristics of R. glutinosa at different densities, this study is expected to provide an important basis for regulating the quality and yield of medicinal materials of R. glutinosa by managing the planting density.

Vaginal microbiome analysis of healthy women during different periods of gestation.

To assess the vaginal microbiome throughout full-term uncomplicated pregnancy, a longitudinal study was designed for 12 healthy women who had prepared to become pregnant and then delivered at term (38-42 weeks) without complications. The vaginal microbial community was studied at pre-pregnancy, 8-12, 24-28, 37-38 weeks of gestation, and puerperium, using hypervariable tag sequencing of the V3-V4 region of the 16S rRNA gene. Sequencing produced approximately 10 million reads on the Illumina MiSeq. Members of the Firmicutes phyla were prevailing before and during pregnancy periods, and the proportion was quite as Proteobacteria until puerperium. Lactobacillus genus was abundant before and during pregnancy, but post-delivery vaginal microflora variety turned diverse. The species-level analysis revealed that a healthy vaginal microbiome before or during pregnancy was prominently dominated by Lactobacillus crispatus. Furthermore, PCoA analysis revealed for differences in the bacterial community composition between the two levels of Lactobacillus species in pre-pregnancy and pregnancy period (PC1 contribution of 58.46%, PC3 contribution of 8.64%). Based on the taxonomic and PCoA analysis, we found that L. crispatus was dominant in the vaginal microflora of healthy women before or during pregnancy, but at the puerperium, the status changed leading to decreased abundance of protective Lactobacillus species that made vaginal micro-ecological barrier vulnerable to diseases. Additionally, vaginal pH was an important environmental property affecting the vaginal microbial community.

Correlation of Social-psychological Health and Joint Function in Patients during Rehabilitation for Joint Impairment / 中国康复理论与实践

Objective:To explore the influence of social-psychological factors on outcome of joint rehabilitation. Methods:From October, 2015 to April, 2017, 64 inpatients accepting joint rehabilitation were divided into anxiety group and non-anxiety group, and depression group and non-depression group, according to the scores of Hamilton Anxiety Scale and Hamilton Depression Scale. They were assessed with routine joint scores as initial and final stages of joint rehabilitation, as well as Symptom Checklist-90 (SCL-90) and World Health Organization Disability Assessment Schedule 2.0 (WHO-DAS 2.0). The correlation of joint scores to scores of SCL-90 and WHO-DAS 2.0 was analyzed with Spearman correlation analysis. Results:There were significant differences in joint scores between the depression and the non-depression groups initially and finally (|t| > 2.106, P < 0.05). The joint score at the initial stage was negatively correlated with the interpersonal factor score of SCL-90 (r = -0.257, P < 0.05). The joint score at the final stage was negatively correlated (P < 0.05) with the dimension one (r = -0.257) and four (r = -0.278) of WHO-DAS 2.0, total score (r = -0.263), and interpersonal (r = -0.328) and hostile (r = -0.385) factor scores of SCL-90. Improvement of joint score negative correlated with dimension one of WHO-DAS 2.0 score (r = -0.249, P < 0.05). Conclusion:The social-psychological factors affect the outcome of joint rehabilitation. It is necessary to explore the way to take the the social-psychological assessment into the routine three stage evaluation of the joint rehabilitation protocol.

Goal-directed Fluid Therapy May Improve Hemodynamic Stability of Parturient with Hypertensive Disorders of Pregnancy Under Combined Spinal Epidural Anesthesia for Cesarean Delivery and the Well-being of Newborns.

BACKGROUND: Hypotension induced by combined spinal epidural anesthesia in parturient with hypertensive disorders of pregnancy (HDP) can easily compromise blood supply to vital organs including uteroplacental perfusion and result in fetal distress. The aim of this study was to investigate whether the goal-directed fluid therapy (GDFT) with LiDCO rapid system can improve well-being of both HDP parturient and their babies. METHODS: Fifty-two stable HDP parturient scheduled for elective cesarean delivery were recruited. After loading with 10 ml/kg lactated Ringer's solution (LR), parturient were randomized to the GDFT and control group. In the GDFT group, individualized fluid therapy was guided by increase in stroke volume (ΔSV) provided via LiDCO rapid system. The control group received the routine fluid therapy. The primary endpoints included maternal hypotension and the doses of vasopressors administered prior to fetal delivery. The secondary endpoints included umbilical blood gas abnormalities and neonatal adverse events. RESULTS: The severity of HDP was similar between two groups. The total LR infusion (P < 0.01) and urine output (P < 0.05) were higher in the GDFT group than in the control group. Following twice fluid challenge tests, the systolic blood pressure, mean blood pressure, cardiac output and SV in the GDFT group were significantly higher, and the heart rate was lower than in the control group. The incidence of maternal hypotension and doses of phenylephrine used prior to fetal delivery were significantly higher in the control group than in the GDFT group (P < 0.01). There were no differences in the Apgar scores between two groups. In the control group, the mean values of pH in umbilical artery/vein were remarkably decreased (P < 0.05), and the incidences of neonatal hypercapnia and hypoxemia were statistically increased (P < 0.05) than in the GDFT group. CONCLUSIONS: Dynamic responsiveness guided fluid therapy with the LiDCO rapid system may provide potential benefits to stable HDP parturient and their babies.

Effect of Meisoindigo on Wnt signal pathway in K562 and HL-60 cells / 中国实验血液学杂志

The aim of this study was to investigate the effect of meisoindigo on Wnt signal pathway in K562 cells and HL-60 cells and its possible regulatory mechanism. RT-PCR and Western blot assay were used to detect the expression of GSK-3beta and its downstream associated genes as well as proteins expression respectively. The results showed that the meisoindigo could inhibit the phosphorylation of GSK-3beta and decreased beta-catenin and c-myc genes expression in HL-60 cells, but did not significantly affect the two gene expression in K562 cells. Meisoindigo slightly increased the expression of GSK-3beta protein in HL-60 cells, obviously decreased the expression of p-GSK-3beta and c-MYC proteins in K562 cells and HL-60 cells, while meisoindigo did not affect the expression of beta-catenin in K562 cells significantly, but could decrease the expression of beta-catenin in HL-60 cells. It is concluded that the meisoindigo can affect the Wnt signal pathway through inhibiting the GSK-3beta expression and down-regulating the beta-catenin and c-MYC protein expression, which play an important role in the treatment for chronic myeloid leukemia.

[The treatment of dorsally displaced intra-articular fractures of the distal radius via palmar approach].

OBJECTIVE: To treat dorsally displaced intra-articular fractures of the distal radius, and to assess the integrity of radiocarpal joint and the reliability of stable fixation fracture. METHODS: Sixty-three cases (65 sides) patients with dorsally displaced intra-articular fractures of the distal radius were performed operatively with the open reduction and internal fixation via palmar approach between August 2003 and May 2008. The series included 20 males (21 sides) and 43 females (44 sides). The mean age of patients was 52.4 years ranging from 18 to 82 years. According to the Frykman classification, 6 sides were of type III, 8 of type IV, 5 of type V, 4 of type VI, 13 of type VII and 29 of type VIII. With the exception of the radiocarpal arthrography and the standard antero-posterior and lateral views of the wrist joint, two new tangential antero-posterior and lateral views of the wrist joint were intraoperatively described so as to observe the relation of the distal screws with the articular surface. RESULTS: The 53 cases (54 sides) of the 63 cases (65 sides) were followed up, and the follow-up time was averagely 16.4 months ranging from 4 to 47 months. According to Gartland and Werley criteria, 32 sides were rated as excellent (59.3%), 14 sides as good (25.9%), 7 fair (13.0%) and 1 poor (1.8%), and the excellent-good rate was 85.2%. Observing the new tangential antero-posterior and lateral views of the wrist joint, it showed that screws appeared penetrating into the radiocarpal joint in 26 of the 42 sides by standard antero-posterior view and in 31 of the 42 sides by standard lateral view. CONCLUSION: This palmar approach represents a simple and valuable treatment methodology for the most frequent types of unstable fractures of the distal radius in young and elderly patients.

<p><b>OBJECTIVE</b>To treat dorsally displaced intra-articular fractures of the distal radius, and to assess the integrity of radiocarpal joint and the reliability of stable fixation fracture.</p><p><b>METHODS</b>Sixty-three cases (65 sides) patients with dorsally displaced intra-articular fractures of the distal radius were performed operatively with the open reduction and internal fixation via palmar approach between August 2003 and May 2008. The series included 20 males (21 sides) and 43 females (44 sides). The mean age of patients was 52.4 years ranging from 18 to 82 years. According to the Frykman classification, 6 sides were of type III, 8 of type IV, 5 of type V, 4 of type VI, 13 of type VII and 29 of type VIII. With the exception of the radiocarpal arthrography and the standard antero-posterior and lateral views of the wrist joint, two new tangential antero-posterior and lateral views of the wrist joint were intraoperatively described so as to observe the relation of the distal screws with the articular surface.</p><p><b>RESULTS</b>The 53 cases (54 sides) of the 63 cases (65 sides) were followed up, and the follow-up time was averagely 16.4 months ranging from 4 to 47 months. According to Gartland and Werley criteria, 32 sides were rated as excellent (59.3%), 14 sides as good (25.9%), 7 fair (13.0%) and 1 poor (1.8%), and the excellent-good rate was 85.2%. Observing the new tangential antero-posterior and lateral views of the wrist joint, it showed that screws appeared penetrating into the radiocarpal joint in 26 of the 42 sides by standard antero-posterior view and in 31 of the 42 sides by standard lateral view.</p><p><b>CONCLUSION</b>This palmar approach represents a simple and valuable treatment methodology for the most frequent types of unstable fractures of the distal radius in young and elderly patients.</p>
