Unraveling the anti-primary dysmenorrhea mechanism of Ainsliaea fragrans Champ. extract by the integrative approach of network pharmacology and experimental verification.

BACKGROUND: The plant Ainsliaea fragrans Champ. (A. fragrans) named "Xingxiang Tuerfeng", is a traditional herb with a long history of therapeutic practice in southern China in the treatment of gynecological diseases. PURPOSE: The anti-inflammatory extract of Ainsliaea fragrans Champ. (AF-ext) exhibited anti-primary dysmenorrhea (PD) activity in oxytocin-induced mice. This study aimed to unravel the underlying mechanisms of AF-ext on PD by the integrative approach of network pharmacology and experimental verification. METHODS: First, the therapeutic targets of AF-ext are predicted using network pharmacology and molecular docking methods. Second, activity screening and immunoblotting methods were used for target validation. Then, the therapeutic effect of AF-ext on PD was evaluated using oxytocin-induced mice and uterine strips model. RESULTS: AF-p1, and AF-p2, the active ingredients of AF-ext, showed inhibitory effects on COX1/2 and EGFR, and all five active components showed antagonistic activity on TRPV1. AF-ext (25, 50, 100 mg/kg) could significantly reduce the number of writhing times and prolong writhing latencies in a dose-dependent manner. AF-ext inhibited spasmolytic activity in uterine strips induced by oxytocin and Ca2+ stimulation. AF-ext inhibited NF-κB/COX-2/PG pathway and activation of the NLRP3 inflammasome in PD mice. It significantly downregulated the PD-induced overexpression of p-p65/p65, p-IκBα, and COX-2 by inhibiting the NF-κB pathway. Moreover, the overexpression of NLRP3, p20/pro-Caspase 1, and p17/pro-IL-1ß was greatly downregulated. CONCLUSIONS: AF-ext demonstrated anti-inflammatory, analgesic, and spasmolytic activity in the treatment of PD. It inhibited the NF-κB/COX-2/PG pathway and NLRP3 inflammasome activation in PD mice with a multi-target approach.

[Dong's extraordinary point needling technique combined with medication for postoperative complications of anal fistula: a randomized controlled trial].

OBJECTIVE: To observe the effect of Dong's extraordinary point needling technique on postoperative complications of anal fistula. METHODS: A total of 241 patients undergoing anal fistula surgery were randomly divided into an observation group (121 cases, 3 cases dropped off) and a control group (120 cases, 2 cases dropped off). The patients in the control group were treated with intramuscular injection of compound diclofenac sodium injection and oral administration of tamsulosin hydrochloride sustained release capsules. In addition to the treatment in the control group, the patients in the observation group were treated with Daoma needling technique at the "Sanqi points" (Qimen point, Qijiao point, and Qizheng point) combined with Dongqi needling technique at "Sanhuang points" (sub-Tianhuang point, Dihuang point, Renhuang point), with each session lasting 30 min. The treatment in the two groups both started on the first day after surgery, and was given once daily for 14 consecutive days. Visual analog scale (VAS) score was compared between the two groups on postoperative day 1, 7, and 14; bladder residual urine volume, spontaneous voiding volume, and urinary catheterization frequency were assessed after treatment on postoperative day 1; and anorectal dynamic indexes (anal canal resting pressure, rectal resting pressure, maximum squeeze pressure of the anal canal, and minimum rectal sensory threshold) were evaluated before surgery and on postoperative day 4. Clinical efficacy was assessed in both groups one month after surgery. RESULTS: On postoperative day 7 and 14, the VAS scores of both groups were lower than those on postoperative day 1 (P<0.05), and the VAS scores in the observation group were lower than those in the control group (P<0.05). The bladder residual urine volume and urinary catheterization frequency in the observation group were lower than those in the control group (P<0.05), while the spontaneous voiding volume was higher than that in the control group (P<0.05). On postoperative day 4, the anal canal resting pressure, maximum squeeze pressure of the anal canal, and the minimum rectal sensory threshold were lower than preoperative values (P<0.05), while the rectal resting pressure was higher than preoperative value (P<0.05) in both groups. The anal canal resting pressure, maximum squeeze pressure of the anal canal, and minimum rectal sensory threshold were lower than those in the control group, and the rectal resting pressure was higher than that in the control group (P<0.05). The effective rate was 93.2% (110/118) in the observation group, which was higher than 84.7% (100/118) in the control group (P<0.05). CONCLUSION: Dong's extraordinary point needling technique could reduce postoperative pain, alleviate urinary retention, and improve defecation in patients undergoing anal fistula surgery.

A case report of Gitelman syndrome in children.

RATIONALE: Giltelman syndrome (GS) is an autosomal recessive infectious disease, which is caused by the mutation of SLC12A3 gene encoding thiazide diuretic sensitive sodium chloride cotransporter located in the distal convoluted tubule of the kidney. PATIENT CONCERNS: A 7-year-old and 3-month-old male patient has poor appetite, slow growth in height and body weight since the age of 3, body weight: 16 kg (-3 standard deviation), height: 110 cm (-3 standard deviation), normal exercise ability and intelligence. One year ago, he was diagnosed with hypokalemia. After potassium supplement treatment, the blood potassium returned to normal. The patient developed abdominal pain, vomiting, limb weakness, and tetany 1 day before admission. DIAGNOSES: After admission examination, the patient was found to have hypokalemia (2.27-2.88 mmol/L), hypomagnesemia (0.47 mmol/L), hypophosphatemia (1.17 mmol/L), hypocalcemia (1.06 mmol/24 hours), and metabolic alkalosis (PH 7.60). The blood pressure is normal, and the concentration of aldosterone is 791.63 pg/mL. The adrenocorticotropic hormone and cortisol detected at 8 am are 4.95 pmol/L and 275.09 nmol/L, respectively. Twenty-four hours of urine potassium is 32.52 mmol. Gene sequencing results showed 2 pathogenic variants in the GS-related SLC12A3 gene, which are related to the phenotype of the subject. INTERVENTIONS: After admission, the patients were given potassium and magnesium supplements, as well as oral spironolactone. The symptoms of limb weakness and tetany were significantly relieved. After discharge, the patients continued to maintain treatment to keep the blood potassium at more than 3.0 mmol/L, and the blood magnesium at more than 0.6 mmol/L. OUTCOMES: Follow-up at 1 month after discharge, in the patient's self-description, he had no symptoms such as limb weakness and tetany, and his height was increased by 1 cm and the body weight increased by 1.5 kg. LESSONS: For patients with hypokalemia, hypomagnesemia, and metabolic alkalosis, the possibility of GS should be given priority. After the diagnosed by gene sequencing of SLC12A3 gene, potassium and magnesium supplementation could significantly improve symptoms.

2D Black Phosphorus-Based Cytomembrane Mimics with Stimuli-Responsive Antibacterial Action Inspired by Endotoxin-Associated Toxic Behavior.

Biomimetic membrane materials have been widely explored and developed for drug loading and tissue engineering applications due to their excellent biocompatibility and abundant reaction sites. However, novel cytomembrane mimics have been lacking for a long time. In this study, black phosphorus (BP) was used as the foundation for a new generation of promising cytomembrane mimics due to its multiple similarities to cytomembranes. Inspired by the dual function of endotoxins on membranes, we prepared a BP-based cytomembrane mimic with controllable antibacterial ability via electrostatic interaction between BP and [1-pentyl-1-quaternary ammonium-3-vinyl-imidazole]Br ([PQVI]Br). The release of PQVI could be manipulated in different conditions by adjusting the electrostatic force, thereby achieving controllable antibacterial ability. This report confirms the possibility of using BP as a new material to mimic cytomembranes and provides a new concept of controllable antibacterial action based on endotoxins.

Sedative and hypnotic effects of compound Anshen essential oil inhalation for insomnia.

BACKGROUNDS: The chemical composition of many essential oils indicates that they have sedative and hypnotic effects, but there is still a lack of systematic studies on the sedative and hypnotic effects of essential oils. In addition, aromatherapy does not seem to have the side effects of many traditional psychotropic substances, which is clearly worthwhile for further clinical and scientific research. The clinical application of essential oils in aromatherapy has received increasing attention, and detailed studies on the pharmacological activities of inhaled essential oils are increasingly needed. HYPOTHESIS/PURPOSE: As insomniacs are usually accompanied by symptoms of depression and anxiety of varying degrees, based on the theory of aromatherapy of Traditional Chinese Medicine, this experiment is to study a Compound Anshen essential oil that is compatible with Lavender essential oil, Sweet Orange essential oil, Sandalwood essential oil and other aromatic medicine essential oils with sedative and hypnotic effects, anti-anxiety and anti-depression effects. To study the sedative and hypnotic effects of Compound Anshen essential oil inhaled and the main chemical components of Compound Anshen essential oil, and to compare and analyze the pharmacodynamics of diazepam, a commonly used drug for insomnia. METHODS: The Open field test and Pentobarbital-induced sleep latency and sleep time experiments were used to analyze and compare the sedative and hypnotic effects of inhaling Compound Anshen essential oil and the administration of diazepam on mice. The changes of 5-HT and GABA in mouse brain were analyzed by Elisa. The main volatile constituents of Compound Anshen essential oil were analyzed by gas chromatography-mass spectrometry (GC-MS). RESULTS: Inhalation of Compound Anshen essential oil can significantly reduce the spontaneous activity of mice, reduce latency of sleeping time and prolong duration of sleeping time. The results of enzyme-linked immunosorbent assay showed that Compound Anshen essential oil can increase the content of 5-HT and GABA in mouse brain. The main volatile chemical constituents of the Compound Anshen essential oil are D-limonene (24.07%), Linalool (21.98%), Linalyl acetate (15.37%), α-Pinene (5.39%), and α-Santalol (4.8%). CONCLUSION: The study found that the inhalation of Compound Anshen essential oil has sedative and hypnotic effect. This study provides a theoretical basis for further research and development of the sedative and hypnotic effects of Compound Anshen essential oil based on the theory of aromatherapy.

[Effect of Small Knife Needle on ß-enorpin and Enkehalin Contents of Tansverse Process Syndrome of the Third Vertebra].

OBJECTIVE: To explore the analgesic mechanism of small knife needle for treating transverse process syndrome of the third vertebra (TPSTV) by observing peripheral and central changesof ß-endorphin (ß-EP) and enkephalin (ENK) contents. METHODS: Totally 30 Japanese white big-ear rabbits of clean grade were divided into 5 groups according to random digit table, i.e., the normal control group, the model group, the small knife needle group, the electroacupunture (EA) group, and the small knife needle plus EA group, 6 in each group. The TPSTV model was established by inserting a piece of gelatin sponge into the left transverse process of 3rd lumbar vertebrae. Rabbits in the small knife needlegroup were intervened by small knife needle. Those in the EA group were intervened by EA at bilateralWeizhong (BL40). Those in the small knife needle plus EA group were intervened by small knife needleand EA at bilateral Weizhong (BL40). Contents of ß-EP and ENK in plasma, muscle, spinal cord, and hypothalamus were determined after sample collection at day 28 after modeling. RESULTS: Compared with the normal control group, contents of ß-EP and ENK in plasma and muscle increased significantly, and contents of ß-EP and ENK in spinal cord and hypothalamus decreased significantly in the model group (P < 0.05, P < 0.01). Contents of ß-EP and ENK approximated normal levels in the three treatment groups after respective treatment. Compared with the model group, the content of ß-EP in muscle decreased, and contents of ß-EP and ENK in hypothalamus increased in the three treatment groups after respective treatment (P < 0.05). There were no significant difference among the three treatment groups (P > 0.05). CONCLUSIONS: Small knife needle treatment and EA had benign regulation on peripheral and central ß-EP and ENK in TPSTV rabbits. Small knife needle treatment showed better effect than that of EA.

[Study on levels of serum phosphorus, bone alkaline phosphatase and 25-hydroxyvitamin D in preterm infants with very low birth weight].

OBJECTIVE: To compare the levels of serum phosphorus, bone alkaline phosphatase and 25-hydroxyvitamin D3 in preterm infants with very low birth weight, and provide evidence for early screening, prevention of metabolic bone disease in preterm infants. METHODS: A total of 110 newborns who met the inclusion criteria were selected in pediatric ward in our hospital. The case group included 60 preterm infants with very low birth weight and control group included 50 full term infants. Fasting blood were taken from the subjects at week 1, 4, and 12 respectively, and ELISA was conducted to quantitatively detect the serum levels of phosphorus, bone alkaline phosphatase and 25-hydroxyvitamin D. RESULTS: The increase of serum 25-hydroxyvitamin D3in case group was smaller than that in control group; the levels of serum phosphorus had no significant difference between two groups. In case group, the level of bone alkaline phosphatase increased at week 1, 4, and 12, and the 25-hydroxyvitamin D3level had significant difference at week 12 (P<0.05). The abnormal rate of 25-hydroxyvitamin D3 level was 26.7% for case group and 0% for control group. CONCLUSION: There were significant differences between case group and control group in levels of bone alkaline phosphatase and 25-hydroxyvitamin D3, suggesting that detecting the serum levels of bone alkaline phosphatase and 25-hydroxyvitamin D3 would facilitate the early diagnosis of metabolic bone disease in preterm infants.

Effect of acupotomy on nitric oxide synthase and beta-endorphin in third lumbar vertebrae transverse process syndrome model rats.

OBJECTIVE: To explore the long-term effects and pain relief mechanism of acupotomy by observing changes in nitric oxide synthase (NOS) and beta-endorphin (beta-EP) in the hypothalamus, spinal cord, and peripheral blood of rats with third lumbar vertebrae (L3) transverse process syndrome. METHODS: Twenty-eight SD rats were randomly assigned to normal, model, electroacupuncture (EA), and acupotomy group. The last three groups were put through an operation to emulate L3 transverse process syndrome. Fourteen days after the simulation operation, EA and acupotomy treatments were applied to the respective groups. Fifty-six days after the simulation operation, biochemistry tests and enzyme-linked immunosorbent assay were used to measure NOS and beta-EP in the hypothalamus, spinal cord, and peripheral blood. RESULTS: Rats with the simulation operation showed significantly higher levels of NOS and beta-EP in the hypothalamus, spinal cord, and peripheral blood than those in the normal group. The EA and acupotomy groups had significantly lower levels of NOS and beta-EP than those in the model group. There was no statistical difference between the EA and acupotomy groups. CONCLUSION: EA and acupotomy treatments significantly lowered NOS and beta-EP levels in the hypothalamus, spinal cord, and peripheral blood and alleviated L3 transverse process syndrome.

Da-Bu-Yin-Wan and Qian-Zheng-San, two traditional Chinese herbal formulas, up-regulate the expression of mitochondrial subunit NADH dehydrogenase 1 synergistically in the mice model of Parkinson's disease.

ETHNOPHARMACOLOGICAL RELEVANCE: Da-Bu-Yin-Wan (DBYW) and Qian-Zheng-San (QZS), two traditional Chinese herbal formulas, were clinically employed to treat Parkinson's disease (PD) for decades. AIM OF THE STUDY: Our previous studies demonstrated neuroprotective effects of DBYW and QZS on mitochondrial function in mice model of PD induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). In present research, we aimed to investigate the possible neuroprotective mechanisms of DBYW and QZS. MATERIALS AND METHODS: The effects of DBYW and QZS on the behavioral changes (pole test), expression of tyrosine hydroxylase (TH) of substantia nigra by immunohistochemistry, monoaminergic contents and activity of striatum by high performance liquid chromatography, neuronal ultrastructure changes by transmission electron microscopy, mitochondrial DNA (mtDNA) damage by long-extension polymerase chain reaction (PCR), and mRNA expression of mitochondrial subunit NADH dehydrogenase 1(ND1) by qualitative real-time PCR were investigated. RESULTS: Present study demonstrated that DBYW and QZS not only ameliorated the behavior induced by the administration of MPTP and synergistically prevented the decreasing of TH expression, but also increased monoaminergic contents and activity, improved the ultrastructural changes, decreased the mtDNA damage, and synergistically up-regulated the expression of ND1 in mRNA level. CONCLUSIONS: These results suggest that DBYW and QZS possess anti-parkinsonism and neuroprotective properties.

[Effect of electroacupuncture on learning-memory ability, and Abeta and LRP1 immunoactivity in hippocampal sulcus microvessels in APP transgenic mice].

OBJECTIVE: To investigate the effect of electroacupuncture (EA) of "Baihui" (GV 20) and "Yongquan" (KI 1) on the expression of amyloid beta protein (Abeta) and low density lipoprotein (LDL) receptor-related protein 1 (LRP 1) in the hippocampal sulcus microvessels in amyloid precursor protein (APP) 695 V717 I transgenic mice, so as to study its mechanism underlying relief of Alzheimer Disease (AD). METHODS: Twelve APP 695 V717 I transgenic mice were randomly divided into model group and EA group. Six C 57 BL/6 mice were used as the control group. EA (2 Hz/100 Hz, 3-5 mA) was applied to "Baihui" (GV 20) and "Yongquan" (KI 1) for 15 min, once every other day for three months. The learning-memory ability of mice was detected by using Lashley III water maze system. The expression level of Abeta(1-42), and LRP 1 in the hippocampal sulcus microvessels were measured by immunohistochemistry. RESULTS: Water maze test showed that the swimming duration from the start to the goal box (terminal) in the Lashley III water maze was significantly longer in the model group than in the control group (P < 0.05), suggesting a markedly lower learning-memory capacity of APP 695 V717 I transgenic mice. Compared with the model group, the swimming duration in the EA group was decreased considerably (P < 0.05). The integrated optical density (IOD) value of hippocampal Abeta(1-42) immunoreaction (IR) positive products in the model group was significantly higher than that in the control group (P < 0.01) and the IOD value of hippocampal LRP 1 IR-positive products in the model group was apparently lower than that in the control group (P < 0.01). In comparison with the model group, the IOD value of Abeta(1-42) IR-positive products in the EA group was obviously lower than that in the model group (P < 0.05), while that of LRP 1 IR-positive products in the EA group was significantly higher than that in the model group (P < 0.05), suggesting down-regulation of hippocampal Abeta(1-42) expression and up-regulation of LRP 1 expression after EA, and reduction of deposition of Abeta in the cerebral microvessels after EA. CONCLUSION: EA can improve the learning-memory capacity of APP transgenic mice, which is closely related to its effects in up-regulating hippocampal LRP 1 expression and down-regulating hippocampal Abeta(1-42) expression.

[Effect of acupotomy lysis on hypothalamic POMC mRNA and PPE mRNA expression in rats with 3rd lumbar vertebrae transverse process syndrome].

OBJECTIVE: To observe the effect of acupotomy lysis (AL) on hypothalamic proopiomelanocortin (POMO) mRNA and preproenkephalin (PPE) mRNA expression in rats with the third lumbar vertebrae transverse process syndrome (TLVTPS) so as to study its underlying mechanism in relieving symptoms of lumbar muscle strain. METHODS: Twenty-four SD rats were randomly divided into normal control group, model group, AL group and electroacupunture (EA) group. The TLVTPS model was established by inserting a piece of gelatin sponge into the posterior of the left 3rd lumbar vertebrae transverse process. AL and EA were applied to the left "Shenshu"(BL 23) and "Yaoyangguan" (GV 3) respectively. The POMC mRNA and PPE mRNA expression levels in the hypothalamus were detected by in situ hybridization. RESULTS: In comparison with the normal group, the integrated optical density (IOD) values of hypothalamic POMC mRNA and PPE mRNA positive cells in the model group were increased significantly (P < 0.01); while compared with the model group, those of POMC mRNA and PPE mRNA positive cells in both left and right hypothalamus were increased further considerably in both AL and EA groups (P < 0.01). No significant differences were found between AL and EA groups in POMC mRNA and PPE mRNA expression levels (P > 0.05). CONCLUSION: AL and EA therapies can increase the expression of POMC mRNA and PPE mRNA in hypothalamus in rats with TLVTPS, which may contribute to its effect in relieving pain in the treatment of lumbar muscle strain.

[Effect of electroacupuncture on the behavior and the expression of amyloid beta-protein, amyloid precursor protein and ChAT in APP 695 V 717 I transgenic mice].

OBJECTIVE: To observe the effect of electroacupuncture (EA) on the expression of amyloid precursor protein (APP) and amyloid beta-protein (Abeta) in hippocampal CA 1 area and cerebral cortex in APP 695 V717 I transgenic mice, so as to investigate its underlying mechanism in improving Alzheimer's disease (AD). METHODS: APP 695 V 717 I transgenic mice were randomly divided into model and EA groups, with 6 cases in each. The other 6 negatively-transgenic mice (C 57 BL/6 J) were used as the normal control group. EA (2 Hz/100 Hz, 3 mA) was applied to "Baihui" (GV 20) and "Yongquan" (KI 1) for 15 min, once every other day for 3 months. The learning-memory ability of mice was measured by Y-type maze test and the expression levels of APP, Abeta, and choline acetyltransferase (ChAT) in the cerebral cotex and hippocampal CA 1 area were detected by immunohistochemistry. RESULTS: In comparison with control group, the times of training for gaining correct reaction and the expression levels of Abeta and APP in both cerebral cortex and hippocampal CA 1 area in model group increased significantly (P < 0.05, P < 0.01), while the expression level of ChAT of cerebral cortex in model group decreased considerably (P < 0.05). Compared to model group, +he times of training for gaining correct reaction and the expression levels of APP in both cerebral cortex and hippocampal CA 1 area, and Abeta in CA 1 area of EA group lowered remarkably (P < 0.05), while those of ChAT in cerebral cortex and hippocampal CA 1 area of EA group increased evidently (P < 0.05, P < 0.01). CONCLUSION: Electroacupuncture can improve the learning-memory capacity of the APP transgenic mice, which may be related to its effects in increasing the production of acetylcholine and lowering the levels of APP and Abeta in the brain.

[Effect of Ginkgo biloba Pingchan Recipe on neuronal nitric oxide synthase mRNA expression in the brain of mouse models of Parkinson disease].

OBJECTIVE: To study the effect of the Chinese compound prescription Ginkgo biloba Pingchan Recipe (GBPR) on experimental Parkinson disease (PD) in mice and explore the possible mechanism. METHODS: Male C57/BL6J mice were divided into normal control, PD model and treatment groups. PD model was established by intraperitoneal injection with 1-methl-4-phenyl-1,2,3,6-tetrahydropyridin (MPTP) in the mice, and in the treatment group, GBPR was administered intragastrically after the injection. The mice were sacrificed 14 and 28 days later, and using in situ hybridization with Digoxin-labeled nNOS cDNA oligonucleotide probe, neuronal nitric oxide synthase (nNOS) mRNA was detected in the striatum and substantia nigra in the brain of mice. RESULTS: nNOS mRNA expression was detected in the striatum and substantia nigra of the PD model mice, and GBPR treatment significantly reduced its expressions. CONCLUSION: GBPR has obvious inhibitory effect against the neurotoxicity of NO probably by producing an anti-oxiditive effect through decreasing nNOS synthesis in the brain.
