Tenglong Buzhong granules inhibits the growth of SW620 human colon cancer.

OBJECTIVE: To observe the anticancer effects of the granular preparation of Tenglong Buzhong decoction (,TBD), i.e Tenglong Buzhong granules (, TBG), in human SW620 colon cancer. METHODS: BALB/c nude mice were subcutaneously transplanted with SW620 cells, and treated with TBG (2.56 g/kg, once per day) and/or 5-Fu (104 mg/kg, once per week) for 21 d. Apoptosis, Caspase activities and cellular senescence were measured by commercial kits. The protein expression and phosphorylation were detected by Western blot or immunohistochemistry. RESULTS: TBG and 5-Fu inhibited tumor growth. The tumor inhibition rate of the TBG, 5-Fu, and TBG+5-Fu groups was 42.25%, 51.58%, and 76.08%, respectively. Combination of TBG and 5-Fu showed synergetic anti-cancer effects. TBG and 5-Fu induced apoptosis, activated caspase-3, -8, and -9, increased SMAC expression, inhibited XIAP expression. TBG induced cellular senescence, upregulated cyclin-dependent kinase inhibitor 1a (CDKN1a) and cyclin-dependent kinase inhibitor 2a (CDKN2a) expression, and inhibited phosphorylation of retinoblastoma-associated protein (RB) and expression of cyclin E1 (CCNE1) and cyclin-dependent kinases (CDK) 2. TBG also inhibited angiogenesis accompanied by downregulation of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1α (HIF-1α). CONCLUSIONS: TBG inhibits SW620 colon cancer growth, induces apoptosis SMAC-XIAP-Caspases signaling, induces cellular senescence through CDKN1a/CDKN2a-RB-E2F signaling, inhibits angiogenesis by down-regulation of HIF-1α and VEGF, and enhances the effects of 5-Fu.

Sensitization characteristics of Juniperus chinensis pollen in Beijing area / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the sensitization characteristics of Juniperus chinensis pollen in patients with allergic rhinitis and/or allergic asthma in Beijing area, and to explore the characteristics of Juniper chinensis pollen sensitized population. Methods: Patients with suspected allergic rhinitis and/or asthma from January 2017 to December 2019 in the outpatient department of Allergy Department of Beijing Shijitan Hospital were selected in this study. Skin prick test (SPT) was performed with Juniper chinensis pollen allergen reagent to compare different age and disease allergen distribution, and to observe the sensitization characteristics of its population. All of the analyses were performed using SAS software version 9.4. Results: A total of 8 380 patients were enrolled in the end. The total positive rate of Juniper chinensis pollen SPT reached 49.92% (4 183/8 380). The positive rate of Juniper chinensis pollen SPT was highest in the 10-14 age group, reaching 60.99% (283/464). Compared with other age groups, there was a statistical difference (χ²=266.77, P<0.01). The SPT positive rate of patients aged less than 10 years increased with the increase of age, while the SPT positive rate of patients aged over 40 years decreased with the increase of age. Single Juniper chinensis pollen was less allergenic, accounting for about 25.05% (1 048/4 183), and the patients' age was (35.21±12.39) years. Regardless of single Juniper chinensis pollen or other pollen allergies, allergic rhinitis was the main disease. Among the patients with SPT positive Juniper chinensis pollen combined with other inhaled pollen allergens, willow pollen accounted for the first (74.99%). The positive rate of Juniper chinensis pollen was the highest in patients with single allergic rhinitis, accounting for 52.05% (3 797/7 295), and the rate in patients with single allergic asthma was the lowest, accounting for 17.49% (53/303), with statistically difference (χ²=138.99, P<0.01). Conclusions: Juniper chinensis pollen is highly sensitized in patients with allergic rhinitis and/or allergic asthma in Beijing . The positive rate of SPT is highest among 10-14 age group, most of which showed strong positive reaction, and allergic rhinitis is more common in Juniper chinensis pollen sensitization diseases.

Correlation Analysis of Adverse Reactions of Antiosteoporosis Drugs by Different Mechanisms with Bone Turnover and Vitamin D.

OBJECTIVE: The risk factors for the most common adverse reactions of two types of antiosteoporosis drugs in the first treatment of postmenopausal osteoporosis were analyzed to investigate the relationship between the occurrence of adverse reactions and different bone transition states and vitamin D levels. METHODS: A total of 381 postmenopausal women who were diagnosed with osteoporosis in the Osteoporosis Clinic of Ningxia Medical University General Hospital from January 2017 to June 2020 were enrolled. A telephone follow-up survey was conducted on the mentioned subjects. According to the survey results, the mentioned subjects were selected according to their first use of antiosteoporosis drugs. They were divided into zoledronic acid and teriparatide acetate groups. The subjects in the two groups were divided into two groups according to the presence or absence of adverse reactions after medication and according to vitamin D level and P1NP level, and the correlation between the two factors and the occurrence of adverse reactions was analyzed. RESULTS: Among the 307 patients treated with zoledronic acid for antiosteoporosis, 99 patients developed acute phase adverse reactions (APR+), accounting for 32.2% of the total subjects. 56.7 percent of the subjects had vitamin D deficiency. The 25(OH)D level of the APR + subjects was 16.75 ± 9.20 ng/mL, significantly lower than that of the APR- patients (23.68 ± 10.67 ng/mL). Serological P1NP level in APR+ patients was 73.95 ± 34.50 ng/ml, significantly higher than that of APR- patients with 55.80 ± 36.91 ng/ml. Musculoskeletal symptoms were observed in 14 of the 74 subjects treated with teriparatide acetate, accounting for 18.9% of the total subjects. The 25(OH)D level was deficient in 59.5% of the subjects. The 25(OH)D level of the subjects with musculoskeletal symptoms was 15.96 ± 8.17 ng/ml, while that of the subjects without musculoskeletal symptoms was 20.86 ± 8.52 ng/ml, which showed no statistical significance. The reason was considered to be related to the small sample size included in the study. The P1NP level of subjects with musculoskeletal symptoms was 96.85 ± 58.52 ng/ml, significantly higher than the P1NP level of subjects without musculoskeletal symptoms (55.28 ± 27.87 ng/ml). CONCLUSIONS: The 25(OH)D level in vivo was negatively correlated with the acute phase adverse reactions after the first infusion of zoledronic acid. When the rate of bone formation is increased and osteoblasts are active, the risk of acute phase adverse reactions is increased with the use of zoledronic acid as antiosteoporosis therapy. There was no significant correlation between 25(OH)D levels and musculoskeletal symptoms after teriparatide acetate treatment of osteoporosis. When the rate of bone formation is increased and osteoblasts are active, the risk of adverse reactions to musculoskeletal symptoms is increased with antiosteoporosis treatment with teriparatide acetate.

Exploratory Study on Expression of Fatty Tissue in Gestational Diabetes Mouse.

OBJECTIVE: To investigate the changes of UCP1 protein in brown fat by establishing a model of gestational diabetes mellitus through intervention of high fat and carbohydrate diet. To explore the changes of UCP1 protein in brown fat in gestational diabetic mice, and analyze the characteristics of abnormal glucose metabolism in gestational diabetic mice and its relationship with changes in adipocyte morphology and insulin resistance. METHODS: Eighty C57BL/6J pregnant mice were randomly divided into a normal control group and a high-fat and high-sugar feeding group. The normal control group was fed a normal diet, while the high-fat and high-sugar group was fed a high-fat and high-sugar diet to establish a gestational diabetes mellitus (GDM) model. On the pregnancy days 0, 10, and 18, the weight and fasting glucose were measured. On the pregnancy day 18, the triglycerides (TG), the total cholesterol (TC), free fatty acid (FFA), insulin levels, and insulin resistance index (HOMA-IR) were measured or calculated. At the same time, brown fat UCP1 protein of the two groups of pregnant mice were measured using Western blot Observed the Adipose tissue pathological changes by staining HE. The adipocyte was observed, and the correlation was analyzed. RESULTS: Twenty-one pregnant mice reach the level of gestational diabetes diagnosis (FBG ≥ 5.1 mmol/L) in the high-fat and high-sugar diet group. On the pregnancy day 10 and 18, the fasting plasma glucose and the body weight significantly increased (P < 0.05). The total cholesterol, triglycerides, free fatty acid, insulin level, and insulin resistance index of the GDM group were also higher compared with that of the control group (P < 0.05). The adipocyte size significantly increased in the GDM mice. TG, TC, FFA, and body weight at 18 days of gestation were significantly correlated with HOMA-IR and single-adipocyte area in the GDM mice. HOMA-IR was significantly correlated with a single-adipocyte area. Compared with the normal control group, the UCP1 proteins of GDM mice decreased significantly and negatively correlated with body weight increase. CONCLUSION: Feeding C57BL/6J pregnant mice with high fat and high sugar to establish a gestational diabetes mouse model has good stability and is similar to human gestational diabetes. The reduction of brown fat UCP1 protein in GDM mice has a certain correlation with obesity tendency and obvious insulin resistance.

Investigation of acupuncture in improving sleep, cognitive and emotion based on attenuation of oxidative stress in prefrontal cortex in sleep-deprived rats / 针灸推拿医学（英文版）

Objective: To explore whether acupuncture can improve sleep disturbance, cognitive impairment and emotional disorders caused by sleep deprivation, and its association with the attenuation of oxidative stress injury in prefrontal cortex. Methods: Fifty-two male Sprague-Dawley rats were randomly divided into a control group (n=10), a model group (n=14), a manual acupuncture (MA) group (n=14), and a sham-MA group (n=14). All the groups were established as sleep deprivation models via the modified multiple platform method, except for the control group. Rats in both the MA group and the sham-MA group received corresponding intervention, respectively. After modeling and intervention, the four groups received three behavioral tests, namely sleep monitoring, by comprehensive lab animal monitoring system (CLAMS), Morris water maze (MWM) test and open-field test (OFT), followed by oxygen free radical level test and Western blot (WB) detection for the expression levels of Bax and Bcl-2. Results: The MA group derived more sleep time within 24 h than either the model group or the sham-MA group (both P<0.05). On MWM orientation navigation test day 1, there were no significant differences in escape latency among the control, MA and sham-MA groups (P>0.05), and the escape latency was significantly shorter in these three groups than that in the model group (all P<0.05). On test day 4, the escape latency was markedly shorter in the MA group than that in either the model group or the sham-MA group (both P<0.05); meanwhile, the MA group showed significantly better performance compared with these two groups in space probe test (both P<0.05). In OFT, compared with the control group, there was a significant decline in the horizontal movement score in the other three groups (all P<0.05), and the decrease was more significant in the model group and the sham-MA group than that in the MA group (both P<0.05). The superoxide dismutase (SOD) content was markedly higher and the malondialdehyde (MDA) content was markedly lower in the MA group than those in the model group and the sham-MA group (all P<0.05). Compared with the model group and the sham-MA group, the expression of Bax was significantly lower and the expression of Bcl-2 was significantly higher in the MA group (all P<0.05). Conclusion: MA therapy can lengthen the sleep time in sleep-deprived rats and improve learning and memory impairments induced by sleep deprivation, and the underlying mechanism may be associated with the enhancement of antioxidant capacity in the prefrontal cortex and the inhibition of hippocampal neuronal apoptosis.

[Effect of Xiaoyao San on OVX combined with CUS anxiety and depression model rats based on hippocampal microglia M1 polarization].

To investigate the anti-anxiety and anti-depression effect and mechanism of Xiaoyao San on rats with ovariectomy(OVX) combined with chronic unpredictable stress(CUS) model. The model of perimenopausal depression was established by OVX and CUS; the level of anxiety and depression was evaluated by open field test; the levels of interleukin-1ß(IL-1ß) and interleukin-6(IL-6) mRNA in rat hippocampus were detected by Real-time qPCR; double staining immunofluorescence was used to detect the expression of ionized calcium binding adaptor molecule-1(Iba-1) and inducible nitric oxide synthase(iNOS) in microglia of rat dentate gyrus(DG); Western blot was used to detect the protein expression of Iba-1 and iNOS of microglia in DG region of rat hippocampus. The results showed that in the model group, the number of horizontal movement, the number of vertical movement and central residence time were significantly reduced, and the grooming time was significantly prolonged(P<0.05 or P<0.01); the levels of IL-1ß and IL-6 in hippocampus increased significantly(P<0.05); the number of positive cells with co-expression of Iba-1/iNOS of microglia cells in DG region of hippocampus increased; the expression levels of Iba-1 and iNOS protein in hippocampus were significantly increased(P<0.01), suggesting that microglia in DG region of hippocampus was activated and polarized toward M1 type in rats with stress. The high dose group of Xiaoyao San significantly increased the number of horizontal movement, vertical movement and central residence time of model rats(P<0.05 or P<0.01), and significantly down-regulated the levels of inflammatory factors IL-1ß and IL-6(P<0.05). Meanwhile, it reversed the activation and quantity change of microglia in hippocampus. Although the Xiaoyao San low dose group had no significant effect on the behavioral indicators in the open field test and the levels of IL-1ß and IL-6, they all showed a trend of improvement. Low dose Xiaoyao San significantly decreased iNOS protein level(P<0.05), and high dose Xiaoyao San significantly down-regulated the protein expression of Iba-1 and iNOS in hippocampus microglia(P<0.05 or P<0.01). In conclusion, Xiaoyao San can improve anxiety and depression-like behavior in OVX combined with CUS model rats, and its mechanism is related to its anti-inflammatory effect by inhibiting M1 polarization of hippocampal microglia.

Biocompatible Interface-Modified Tissue Engineering Chamber Reduces Capsular Contracture and Enlarges Regenerated Adipose Tissue.

Adipose flap expansion using a tissue engineering chamber (TEC) presents a promising candidate for soft tissue regeneration by activating in situ adipose tissue regeneration. However, foreign body reaction (FBR) and capsular contracture caused by a silicone chamber limit large tissue reconstruction. Here, a hydrophilic and biodegradable film made of poly(ethylene glycol) diacrylate (PEG-da) with methacrylated gelatin (gelatin-MA) was presented between the host tissue and silicone chamber to tune the local wound and to prevent initiation of FBR. After a 60 day investigation, 6.1-fold-regenerated fat tissue was obtained from the PEG-gelatin group, whereas only 3-fold tissue was harvested from a silicone group. Histological staining demonstrated that the structure of the neo-formed adipose tissue in both groups was similar to mature adipose tissue. Noticeably, a more distinct and denser fibrous capsule was observed in the silicone group compared to the PEG-gelatin group. Immunohistochemistry of CD206 and TGF-ß expression indicated less M2 macrophage infiltration and a minor inflammation reaction with PEG-gelatin assistance. Less collagen deposition and myofibroblast activation in the PEG-gelatin group were demonstrated via α-SMA and type I collagen staining. All these demonstrated that a biocompatible membrane supplement can attenuate capsule formation and contracture leading to a larger tissue regeneration through the TEC technique, which could lead to new perspectives to the relationship between materials-mattered FBR and tissue regeneration.

AIM: To observe the long - term effect of visual perceptual learning to correct anisometropic amblyopia in children.?METHODS: The clinical data of 200 children (200 eyes) with anisometropic amblyopia were retrospectively analyzed, which were divided into 2 groups according to therapeutic methods, and 82 children treated with traditional integrative therapy were distributed to the control group, while 118 children treated with visual perceptual learning were distributed to the observation group. After 1 year's treatment, the corrected vision, contrast sensitivity and stereo sharpness of patients were compared between groups.?RESULTS:After 1 year's treatment, the effective rate of the observation group was higher than the controls (90. 7％ vs 75. 6％, P<0. 05), and after 1 year's follow up, there was 92. 5％ patients maintained stabilization in the observation group, while that in the control group was 80. 6％, and the observation group was higher than the controls too, the difference between groups had statistical significance (P<0. 05). Before treatment, there was no significant difference in contrast sensitivity between groups (P>0. 05). After 6 and 12 months' treatment, the contrast sensitivity of both groups increased(P<0. 05), and the observation group was higher than the controls after 12 months' treatment, the difference between groups had statistical significance (P<0. 05). Before treatment, there was no significant difference in stereopsis acuity between groups ( P > 0. 05 ). After treatment, the stereopsis acuity of the observation group was better than the controls, and the difference between groups had statistical significance (P<0. 05).?CONCLUSION: The long-term curative effect of visual perception learning to correct children's refractive aberration is better than traditional comprehensive therapy.

Rhododendron oldhamii leaf extract improves fatty liver syndrome by increasing lipid oxidation and decreasing the lipogenesis pathway in mice.

Some members of Rhododendron genus are traditionally used as medicinal plants for arthritis, acute and chronic bronchitis, asthma, pain, inflammation, rheumatism, hypertension and metabolic diseases. To the best of our knowledge, there is no report on the protective effects of R. oldhamii leaf extract on non-alcoholic fatty liver disease (NAFLD) in vivo and in vitro. In this study, the effects of R. oldhamii leaf extract on inhibiting the free fatty acid (FFA)-induced accumulation of fat in HepG2 cells and on improving fatty liver syndrome in mice with high fat diet (HFD)-induced NAFLD were investigated. For the in vitro assay, HepG2 cells were treated with FFAs (oleate/palmitate = 2:1) with or without treatment with R. oldhamii leaf ethyl acetate (EtOAc) fraction to observe lipid accumulation using Nile red and oil red O stains. For the in vivo assay, C57BL/6 mice were randomly assigned to three groups (n = 5), including the normal diet group, the HFD group and the HFD+EtOAc group. After 11 weeks, body weight, serum biochemical indices and the mRNA expressions of the liver tissue, as well as the outward appearance, weight and histopathological analysis of liver and adipose tissues were evaluated. Among the fractions derived from R. oldhamii leaf, the EtOAc fraction exhibited a strong fat-accumulation inhibitory activity. Following reverse-phase high-performance liquid chromatography (HPLC), four specific phytochemicals, including (2R, 3R)-astilbin (AS), hyposide (HY), guaijaverin (GU) and quercitrin (QU), were isolated and identified from the EtOAc fraction of R. oldhamii leaf extract. Among them, AS and HY showed excellent fat-accumulation inhibitory activity. Thus, the EtOAc fraction of R. oldhamii leaf and its derived phytochemicals have great potential in preventing FFA-induced fat accumulation. In addition, the EtOAc fraction of R. oldhamii leaf significantly improved fatty liver syndrome and reduced total cholesterol (TC) and triglyceride (TG) in HFD-induced NAFLD mice at a dosage of 200 mg/kg BW. These results demonstrated that the methanolic extracts from R. oldhamii leaf have excellent inhibitory activities against fat accumulation and anti-NAFLD activities and thus have great potential as a natural health product.

GTS40, an active fraction of Gou Teng-San (GTS), protects PC12 from HO-induced cell injury through antioxidative properties / 中国天然药物

Oxidative stress, a predominant cause of apoptosis cascades triggered in neurodegenerative disorders, has been regarded as a critical inducement in the pathogenesis of Alzheimer's disease (AD). Gou Teng-San (GTS) is a traditional Chinese herbs preparation commonly utilized to alleviate cognitive dysfunction and psychological symptoms of patients with dementia. The present study aimed to investigate the protective effects of GTS40, an active fraction of GTS, on HO-induced oxidative damage and identify the potential active ingredients. Our results revealed that GTS40 exhibited radical scavenging activity, elevated cell viability, decreased the levels of intracellular reactive oxygen species (ROS), and stabilized mitochondrial transmembrane potential (MMP) in HO-treated PC12 cells. In addition, GTS40 blocked the apoptotic cascade by reversing the imbalance of Bcl-2/Bax and inhibiting the activity of caspase-3. Furthermore, an HPLC-QTOFMS method was developed to characterize major chemical constituents in GTS40. Our results revealed twenty-seven identified or tentatively characterized compounds through comparing their retention time (t) and MS spectra with reference standards. These results suggested that GTS40 was a promising active fraction that may be beneficial in the prevention and treatment of oxidative stress-mediated neurodegenerative disorders.

Compared with the baseline, the patients achieved significantly increased IIEF-5 scores after 2 and 4 weeks of medication (15.01 ± 2.25 vs 16.96 ± 2.55 and 19.41 ± 2.82, P <0.05), penileelectionhardness remarkably improved at 4 weeks (3.36% vs 44.58%, P<0.05), and the positive answers to SEP-2 and SEP-3 both markedly increased at 2 (38.11% vs 90.49%, P<0.05; 22.01% vs 63.77% , P<0.05) and 4 weeks (38.11% vs 96.95% , P<0.05; 22.01% vs 89.73%, P<0.05).@*CONCLUSIONS@#TCM combined with sildenafil is safe and effective in the treatment of ED in Chinese men, which can significantly improve the IIEF-5 score and erection hardness of the patients.

Modified stapled transanal rectal resection combined with perioperative pelvic floor biofeedback therapy in the treatment of obstructed defecation syndrome / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical efficacy and safety of modified stapled transanal rectal resection (STARR) combined with perioperative pelvic floor biofeedback therapy (POPFBFT) in treating obstructed defecation syndrome (ODS).</p><p><b>METHODS</b>Thirty female ODS patients underwent modified STARR (resection and suture was performed in rectocele with one staple) combined with POPFBFT in Department of Colorectal and Anal Surgery, The First Hospital of Jilin university from October 2013 to March 2015. Before the modified STARR, patients received a course of POPFBFT (20 min/time, 2 times/d, 10 times as a course), and another 2 courses were carried out in clinic after discharge. Efficacy evaluation included general conditions of patients, morbidity of postoperative complication, overall subjective satisfaction (excellent: without any symptoms; good: 1 to 2 times of laxatives per month and without the need of any other auxiliary defecation; fairly good: more than 3 times of laxatives per month ; poor: with no improvement; excellent, good, fairly good are defined as effective), Longo ODS score (range 0 to 40 points, the higher the score, the more severe the symptoms), gastrointestinal quality of life index(GIQLI)(range 0 to 144 points, the lower the score, the more severe the symptoms), anorectal manometry and defecography examination. The follow-up lasted 12 months after operation (ended at April 2016).</p><p><b>RESULTS</b>Average age of 30 patients was 57(46 to 72) years and Longo ODS score of every patient was ≥9 before operation. The modified STARR was completed successfully in all the 30 patients with average operation time of 25 (18 to 34) min and average hospital stay of 6(4 to 9) d. Postoperative complications included pain(20%, 6/30), urinary retention (16.7%, 5/30), anorectal heaviness (6.7%, 2/30), and fecal urgency(26.7%, 8/30). Anaorectal heaviness and fecal urgency disappeared within 3 months. No severe complications, such as postoperative bleeding, infection, rectovaginal fistula, anastomotic dehiscence and anal incontinence were observed. The effective rate of overall subjective satisfaction was 93.3%(28/30) during the follow-up of 12 months. There was no significant difference in Longo ODS score between pre- POPFBFT and pre-operation (pre- POPFBFT: 32.95±3.22, pre-operation: 32.85±3.62, t=1.472, P=0.163). Compared with pre-POPFBFT, Longo ODS score at 1 week after operation decreased (t=4.306, P=0.000), moreover, score at 1 month after operation was lower than that at 1 week (13.05±7.49 vs. 15.00±7.17, t=7.322, P=0.000), while no significant differences were found among 1, 3, 6, 12 months after operation (F=2.111, P=0.107). Likewise, there was no significant difference in GIQLI score between pre-POPFBFT and pre-operation (pre-POPFBFT: 79.39±17.14, pre-operation: 76.65±17.56, t=1.735, P=0.096). Compared with the pre-POPFBFT, GIQLI score at 1 week after operation increased (t=4.714, P=0.000), moreover, GIQLI score at 1 month after operation was higher than that at 1 week (102.26±19.24 vs 91.31±21.35, t=5.628, P=0.000), while no significant differences were found among 1, 3, 6, 12 months after operation(F=1.211, P=0.313). In comparison with pre- POPFBFT, parameters of defecography examination at 12 months after operation showed obvious improvement: the rectocele decreased from (34.1±0.4) mm to (3.1±0.3) mm (t=6.847, P=0.000), anorectal angle during defecation increased from (123.8±6.7)degree to (134.7±8.5)degree, enlargement of anorectal angle during defecation increased from (29.1±3.5)degree to (37.1±5.3)degree, while no significant differences in descend of perineum, anorectal angles at rest as well as parameters of anorectal manometry were found (all P>0.05).</p><p><b>CONCLUSION</b>Modified STARR combined with POPFBFT is safe and effective for ODS patients.</p>

Effect of two administration routes of Shenmai Injection () on pulmonary gas exchange function after tourniquet-induced ischemia-reperfusion / 中国结合医学杂志

<p><b>OBJECTIVE</b>To compare the effect between nebulized and intravenous administration of Shenmai Injection () on pulmonary gas exchange function of patients following tourniquet-induced lower limb ischemia-reperfusion.</p><p><b>METHODS</b>Thirty-eight patients scheduled for lower extremity surgery were randomized into three groups using the closed envelop method: Shenmai Injection was administered 30 min before tourniquet inflflation by nebulization [0.6 mL/kg in 10 mL normal saline (NS)] in the nebulization group or by intravenous drip (0.6 mL/kg dissolved in 250 mL of 10% glucose) in the intravenous drip group, and equal volume of NS was given intravenously in the NS group; 15 in each group. Arterial blood gases were analyzed, serum levels of malonaldehyde (MDA) and interleukine-6 (IL-6) and interleukine-8 (IL-8) were determined using the method of thiobarbituric acid reaction and enzyme-linked immuno sorbent assay respectively just before tourniquet inflflation (T0), and at 0.5 h (T1), 2 h (T2), 6 h (T3) after tourniquet deflflation.</p><p><b>RESULTS</b>Compared with baselines at T0, MDA levels signifificantly increased at T2, T3 in the NS group and at T3 in the nebulization group, and IL-6 and IL-8 levels were signifificantly increased at T2, T3 in NS, the intravenous drip and the nebulization groups (P <0.05). Arterial pressure of oxygen (PaO) at T3 was decreased, while alveolararterial oxygen tension showed difference (PA-aDO) at T3 in the NS group; RI at T3 in both intravenous drip and the nebulization groups were enhanced (P <0.05). Compared with the NS group, MDA and IL-8 levels at T2, T3, IL-6 at T3 in the intravenous drip group, and IL-8 at T3 in the nebulization group were all remarkably increased (P <0.05). Additionally, MDA level at T3 in the nebulization group was higher than that in the intravenous drip group (P <0.05).</p><p><b>CONCLUSIONS</b>Intravenous administration of Shenmai Injection provided a better protective effect than nebulization in mitigating pulmonary gas exchange dysfunction in patients following tourniquet-induced limb ischemia-reperfusion.</p>

Effect of Pre-intervention with Electroacupuncture at Neiguan (PC 6) plus Intra-operative Administration ofα2-adrenoceptor Agonist on Peri-operative Heart Rate Variability / 上海针灸杂志

Objective To observe the effect of pre-intervention with electroacupuncture at Neiguan (PC 6) plusα2-adrenoceptor (α2AR) agonist on peri-operative heart rate variability (HRV).Method A total of 120 patients going to receive lower limb orthopedic surgery were randomized into four groups by using the random number table, namely a control group (group A), an electroacupuncture group (group C), anα2AR agonist group (group D) and an electroacupuncture plus medication group (group N), 30 cases in each group. The indicators of heart rate variability (HRV), including the standard deviation of normal-to-normal (N-N) intervals (SDNN), standard deviation of the average of N-N intervals (SDANN), root mean square successive differences (rMSSD), percentage of adjacent N-N intervals>50 ms apart (pNN50), low-frequency power (LF), high-frequency power (HF), LF/HF and total power (TP) were recorded 1 d prior and 1 d after the operation; meanwhile, the mean arterial pressure (MAP) and heart rate (HR) were recorded before incubation (T0), right after incubation (T1), 5 min after incubation (T2), right afterextubation (T3), 5 min after extubation (T4), 60 min after extubation (T5), and 180 after extubation (T6).Result In group N, the HR and MAP at the other time points were insignificantly different from those at T0 (P>0.05); in group A, the HR and MAP at T1-T6 were significantly different from those at T0 (P<0.05); in group C and D, the HR and MAP at T1-T4 were significantly different from those at T0 (P<0.05); the HR and MAP in group N were significantly lower than those in group A at T1-T6 (P<0.05) and were significantly lower than those in group C and D at T1-T4 (P<0.05); the HR and MAP in group C and D were significantly lower than those in group A at T5 and T6 (P<0.05). In group A, the LF, HF, LF/HF and TP 1 d after the operation were significantly increased compared to those 1 d prior to the operation (P<0.05); in group A and D, the SDNN, SDANN, rMSSD, and pNN501 d after the operation were significantly lower than those 1 d prior to the operation (P<0.05); the LF, HF, LF/HF, and TP in group C, D and N were significantly lower than those in group A 1 d after the operation (P<0.05); the SDNN, SDANN, rMSSD, and pNN50 in group C and N were significantly higher than those in group A and D 1 d after the operation (P<0.05). Conclusion Pre-intervention electroacupuncture plusα2AR agonist can improve the balance of cardiac sympathetic and vagus nerves, and better maintain the peri-operative hemodynamic stability.
