SrCl2·6H2O: An Alkaline-Earth-Metal Chloride Hexahydrate as Deep-Ultraviolet Nonlinear-Optical Crystal with the {[Sr(H2O)6]2+}∞ Cationic Framework.

Exploring deep-ultraviolet (DUV) nonlinear-optical (NLO) materials is significant for the conversion of high-frequency laser. Herein, two alkali-earth-metal halide hexahydrates, SrX2·6H2O (X = Cl, Br), were obtained, and the centimeter-sized single crystals of SrCl2·6H2O were grown by a slow evaporation method. Both of them crystallize in the trigonal space group P321, and their crystal structures show {[Sr(H2O)6]2+}∞ cationic chains, with isolated Cl- or Br- anions interspersed between the chains. SrCl2·6H2O exhibits a moderate second-harmonic-generation response (0.4 × KDP) at 1064 nm and can realize phase matching. Importantly, SrCl2·6H2O has a short ultraviolet cutoff edge (<200 nm). Crystal growth, crystal structures, optical performances, and theoretical calculations of the title and related compounds have been discussed in this work. This study enriches the understanding of metal halide hydrates as NLO materials in the DUV region.

Cation Regulation to Investigate the Chalcogenide Borate RE6Nb2MgSB8O26 (RE = La-Nd) Family.

Chalcogenide borates have been developed and are considered an attractive system due to their favorable physical properties such as magnetism and nonlinear optical effects. Here, isostructural RE6Nb2MgSB8O26 (RE = La-Nd) compounds in the title family have been obtained through cation regulation in rare-earth and VB group metals. This family crystalizes in the centrosymmetric P3̅ space group and features 3D frameworks formed by {[Mg(NbB4O13)2]16-}∞ polyanionic layers and QRE6 octahedra. The structural chemistry was characterized and theoretical calculations were performed to understand the structural merit of this family. In addition, RE6Nb2MgSB8O26 possess the largest band gaps among known rare-earth chalcogenide borates, and they all show antiferromagnetic-like behaviors.

Three-in-One Strategy Constructing a Series of Hybrid Tetrahedral Motif-Based Selenides with Balanced Second-Order Nonlinear Optical Performance.

Concurrently achieving suitable second harmonic generation (SHG) effect and high laser-induced damage threshold (LIDT) is challenging for infrared nonlinear optical (NLO) materials. Here, a series of pentanary infrared NLO materials CsMIIIMIVSnSe6 (MIII = Ga, In; MIV = Si, Ge) have been obtained by a three-in-one strategy, viz. three kinds of elements (MIII, MIV, and Sn) in one position, which is first adopted to design NLO materials. Their three-dimensional structures are constructed by the MQ4 (M denotes MIII, MIV, and Sn) tetrahedral units. They exhibit promising hybrid NLO properties, witnessed by their moderate/large SHG effects of 0.52, 0.98, 1.05, and 1.12 × AgGaS2, and high powder LIDT values of 6.9, 4.1, 8.1, and 5.4 × AgGaS2, respectively. These NLO properties are well verified by the DFT calculation results. The three-in-one strategy of designing high-performance infrared NLO materials will stimulate more investigations in this field.

[Protecting Effects of Jian'erji on Age-related Hearing Loss of C57BL/6J Mice].

Objective To observe decreased hearing in aged C57BL/6J mice, and to study pro- tective effects of Jian' erji ( JEJ ) for age-related hearing loss (AHL) and its possible mechanism. Methods Totally 36 C57BL/6J mice were randomly divided into four groups, i.e., the normal control group (n =6) , the AHL control group (n =12) , the high dose JEJ group (n =12) , the low dose JEJ group (n =6). Mice in the normal control group drank tap water from ablactation till 2 months old. Mice in the AHL control group drank tap water from ablactation till 7 months old. Mice in high and low dose JEJ groups drank JEJ at the daily dose of 3. 65 g/kg and 0. 91 g/kg respectively from ablactation till 7 months old. Six mice were selected from each group for auditory brainstem response (ABR) using brainstem evoked potentiometer on the day of ending the test. The cochlear tissue, auditory cortex, and liver were immediately collected from 6 mice of the high dose JEJ group and 6 of the AHL control group at the same ages. Contents of malondialdehyde (MDA) , end product of lipid peroxidation were detected by UV spectrophotometer using MDA coomassie blue kit. Results ABR thresholds evoked by short-pure tone from 4 to 48 KHz were in the normal range of 2 months old mice in the normal control group. Compared with 2 months old mice in the normal control group, ABR thresholds were significantly elevated in 7 months old mice of the AHL control group (P <0. 05). Significant differences also existed in ABR thresholds from 8 to 48 KHz in the high dose JEJ group (P <0. 05). Compared with 7 months old mice of the AHL control group, MDA contents in cochlear tissue, auditory cortex, and liver were obviously reduced in the high dose JEJ group (P <0. 01). Conclusions C57BL/6J mice showed significant symptoms of AHL in high frequency range at 7 months old. Daily drinking of high dose JEJ could significantly delay the occurrence and progress of AHL. Its protection might be related to antioxidant effects JEJ contained.

Echocardiographic evaluation of the effect of dapagliflozin on epicardial adipose tissue and left ventricular systolic function in type 2 diabetes mellitus.

BACKGROUND AND AIMS: Epicardial adipose tissue (EAT) is associated with cardiovascular disease, and sodium-glucose cotransporter-2 inhibitors (SGLT-2I) have been reported to reduce the occurrence of cardiovascular events. This study was designed to investigate the effect of an SGLT-2 inhibitor (dapagliflozin) on EAT and left ventricular (LV) systolic function in type 2 diabetes mellitus (T2DM) patients during a 6-month follow-up. METHODS: Twenty-seven T2DM patients who received dapagliflozin for the first time were enrolled in this study to measure EAT thickness and evaluate LV function before and after 6 months of SGLT-2 administration. The thickness of EAT was measured as the echo-free space between the free wall of the right ventricle and the visceral layer of the pericardium at end-systole by echocardiography. LV systolic function was evaluated by LV global longitudinal strain (LV GLS) obtained through two-dimensional speckle tracking echocardiography (2D-STE) technology. RESULTS: After a 6-month follow-up, twenty-five patients completed this study. The values of EAT thickness, HbA1c, body weight, body mass index (BMI), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were significantly reduced, while the LV GLS value was significantly increased. Moreover, the increase in LV GLS was independently associated with the reduction in EAT thickness, HbA1c, weight, and SBP (all p < 0.05). CONCLUSIONS: Dapagliflozin can reduce EAT thickness and improve LV systolic function in T2DM patients. 2D-STE can be used for the early evaluation of the beneficial effect of dapagliflozin on LV systolic function. The improvement in LV systolic function is independently associated with a reduction in EAT thickness.

Can acupuncture enhance therapeutic effectiveness of antidepressants and reduce adverse drug reactions in patients with depression? A systematic review and meta-analysis.

BACKGROUND: Some depressed patients receive acupuncture as an adjunct to their conventional medications. OBJECTIVE: This review aims to provide evidence on whether acupuncture can enhance the therapeutic effectiveness of antidepressants for treating depression, and explore whether acupuncture can reduce the adverse reactions associated with antidepressants. SEARCH STRATEGY: English and Chinese databases were searched for randomized controlled trials (RCTs) published until December 1, 2021. INCLUSION CRITERIA: RCTs with a modified Jadad scale score ≥ 4 were included if they compared a group of participants with depression that received acupuncture combined with antidepressants with a control group that received antidepressants alone. DATA EXTRACTION AND ANALYSIS: Meta-analysis was performed, and statistical heterogeneity was assessed based on Cochran's Q statistic and its related P-value. Primary outcomes were the reduction in the severity of depression and adverse reactions associated with antidepressants, while secondary outcomes included remission rate, treatment response, social functioning, and change in antidepressant dose. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to evaluate the overall quality of evidence in the included studies. RESULTS: This review included 16 studies (with a total of 1958 participants). Most studies were at high risk of performance bias and at low or unclear risk of selection bias, detection bias, attrition bias, reporting bias, and other bias. Analysis of the 16 RCTs showed that, compared with antidepressants alone, acupuncture along with antidepressants reduced the Hamilton Depression Rating Scale-17 (HAMD-17) scores (standard mean difference [SMD] -0.44, 95% confidence interval [CI] -0.55 to -0.33, P < 0.01; I2 = 14%), Self-rating Depression Scale (SDS) scores (SMD -0.53, 95% CI -0.84 to -0.23, P < 0.01; I2 = 79%), and the Side Effect Rating Scale (SERS) scores (SMD -1.11, 95% CI -1.56 to -0.66, P < 0.01; I2 = 89%). Compared with antidepressants alone, acupuncture along with antidepressants improved World Health Organization Quality of Life-BREF scores (SMD 0.31, 95% CI 0.18 to 0.44, P < 0.01; I2 = 15%), decreased the number of participants who increased their antidepressant dosages (relative risk [RR] 0.32, 95% CI 0.22 to 0.48, P < 0.01; I2 = 0%), and resulted in significantly higher remission rates (RR 1.52, 95% CI 1.26 to 1.83, P < 0.01; I2 = 0%) and treatment responses (RR 1.35, 95% CI 1.24 to 1.47, P < 0.01; I2 = 19%) in terms of HAMD-17 scores. The HAMD-17, SDS and SERS scores were assessed as low quality by GRADE and the other indices as being of moderate quality. CONCLUSION: Acupuncture as an adjunct to antidepressants may enhance the therapeutic effectiveness and reduce the adverse drug reactions in patients receiving antidepressants. These findings must be interpreted with caution, as the evidence was of low or moderate quality and there was a lack of comparative data with a placebo control.

Modulation of the gut microbiota and lipidomic profiles by black chokeberry (Aronia melanocarpa L.) polyphenols via the glycerophospholipid metabolism signaling pathway.

Black chokeberry (Aronia melanocarpa L.) is rich in polyphenols with various physiological and pharmacological activities. However, the relationship between the modulation effect of black chokeberry polyphenols on obesity and the alteration of lipid metabolism is not clearly understood. This study aimed to investigate the beneficial effects of the black chokeberry polyphenols (BCPs) treatment on the structure of gut microbiota, lipid metabolism, and associated mechanisms in high-fat diet (HFD)-induced obese rats. Here, we found that a high-fat diet promoted body weight gain and lipid accumulation in rats, while oral BCPs supplementation reduced body weight, liver, and white adipose tissue weight and alleviated dyslipidemia and hepatic steatosis in HFD-induced obese rats. In addition, BCPs supplementation prevented gut microbiota dysbiosis by increasing the relative abundance of Bacteroides, Prevotella, Romboutsia, and Akkermansia and decreasing the relative abundance of Desulfovibrio and Clostridium. Furthermore, 64 lipids were identified as potential lipid biomarkers through lipidomics analysis after BCPs supplementation, especially PE (16:0/22:6), PE (18:0/22:6), PC (20:3/19:0), LysoPE (24:0), LysoPE (24:1), and LysoPC (20:0). Moreover, our studies provided new evidence that composition of gut microbiota was closely related to the alteration of lipid profiles after BCPs supplementation. Additionally, BCPs treatment could ameliorate the disorder of lipid metabolism by regulating the mRNA and protein expression of genes related to the glycerophospholipid metabolism signaling pathway in HFD-induced obese rats. The mRNA and protein expression of PPARα, CPT1α, EPT1, and LCAT were significantly altered after BCPs treatment. In conclusion, the results of this study indicated that BCPs treatment alleviated HFD-induced obesity by modulating the composition and function of gut microbiota and improving the lipid metabolism disorder via the glycerophospholipid metabolism signaling pathway.

The polyphenol-rich extract from chokeberry (Aronia melanocarpa L.) modulates gut microbiota and improves lipid metabolism in diet-induced obese rats.

The gut microbiota plays a critical role in obesity and lipid metabolism disorder. Chokeberry (Aronia melanocarpa L.) are rich in polyphenols with various physiological and pharmacological activities. We determined serum physiological parameters and fecal microbial components by using related kits, liquid chromatography-mass spectrometry (LC-MS) and 16S rRNA gene sequencing every 10 days. Real-time PCR analysis was used to measure gene expression of bile acids (BAs) and lipid metabolism in liver and adipose tissues. We analyzed the effects of different Chokeberry polyphenol (CBPs) treatment time on obesity and lipid metabolism in high fat diet (HFD)-fed rats. The results indicated that CBPs treatment prevents obesity, liver steatosis and improves dyslipidemia in HFD-fed rats. CBPs modulated the composition of the gut microbiota with the extended treatment time, reducing the Firmicutes/Bacteroidetes ratio (F/B ratio) and increasing the relative abundance of Bacteroides, Prevotella, Akkermansia and other bacterial species associated with anti-obesity properties. We found that CBPs treatment gradually decreased the total BAs pool and particularly reduced the relative content of cholic acid (CA), deoxycholic acid (DCA) and enhanced the relative content of chenodeoxycholic acid (CDCA). These changes were positively correlated Bacteroides, Prevotella and negatively correlated with Clostridium, Eubacterium, Ruminococcaceae. In liver and white adipose tissues, the gene expression of lipogenesis, lipolysis and BAs metabolism were regulated after CBPs treatment in HFD-fed rats, which was most likely mediated through FXR and TGR-5 signaling pathway to improve lipid metabolism. In addition, the mRNA expression of PPARγ, UCP1 and PGC-1α were upregulated markedly in interscapular brown adipose tissue (iBAT) after CBPs treatment. We confirmed that CBPs could reduce the body weight of HFD-fed rats by accelerating energy homeostasis and thermogenesis in iBAT. Finally, the fecal microbiota transplantation (FMT) experiment results demonstrated that FMT from CBPs-treated rats failed to reduce the weight of HFD-fed rats. However, FMT from CBPs-treated rats improved dyslipidemia and reshaped gut microbiota in HFD-fed rats. In conclusion, CBPs treatment improved obesity and complications by regulating gut microbiota in HFD-fed rats. The gut microbiota plays an important role in BAs metabolism after CBPs treatment, and BAs have therefore emerged as major effectors in microbe-host signaling events that influence host lipid metabolism, energy metabolism and thermogenesis.

Integrated approach for identifying and evaluating the quality of Marsdenia tenacissima in the medicine market.

The accurate identification and quality evaluation of herbal medical plants is highly necessary to ensure their safety and efficacy. In present study, a new strategy combining DNA barcoding techniques with thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC) was proposed to facilitate the identification and quality control of M. tenacissima. In present work, the internal transcribed spacer 2 (ITS2) barcode was successfully used to identify 58 M. tenacissima samples and its adulterants. TLC successfully identified the other three M. tenacissima samples that failed to produce ITS2 regions. An adulterant was found in all the 62 samples. Moreover, the content of active medicinal ingredients is important for herbal plants quality. The content of tenacissoside H (TS-H) of M. tenacissima samples was determined by HPLC to range from 0.39% to 1.09%, which meets the criterion of the Chinese Pharmacopoeia. Thus, DNA barcoding coupled with TLC and HPLC is very promising to identify and evaluate the quality of M. tenacissima in the medicine market.

[Comparison of Extracellular and Intracellular Fluid Distribution Between Stomach Meridian or Gallbladder Meridian and Their Neighboring Tissues of Lower Leg in Healthy Volunteers].

OBJECTIVE: To compare differences of extracellular fluid impedance (Re) and intracellular fluid impedance (Ri) between the Stomach(ST) Meridian or Gallbladder(GB) Meridian and their neighboring non-meridian sites of the left lower leg at the same level, so as to explore the distribution characteristics of body fluid in the meridian. METHODS: Sixteen healthy volunteers were enrolled in the present study. The Re and Ri were detected by using Ag/AgCl electrodes and a digital lock-in amplifier. The measuring electrodes (at an interval of about 3 cm) were separately fixed to the skin sites covering the running courses of the ST Meridian (in the lateral interspace of the anterior tibial muscle)and the GB Meridian (in the interspace of the anterior edge of the fibula), and the excitation electrodes (at an interval of about 9 cm) respectively fixed to the skin sites covering the anterior tibial muscle and the interspace between the anterior tibial muscle and the tibia (about 2 cm and 5 cm lateral to the ST and GB meridians, and about 3－4 cm and 6－8 cm lateral to the ST and GB meridians, respectively). A 100 µA constant current with frequencies from 1 kHz to 100 kHz delivered via an excitation electrode was applied to the site (control spots of the ST Meridian), and signals of the voltage amplitude and phase difference of the tissues fed to the lock-in amplifier via the measuring electrode were collected, followed by measuring those of the GB Meridian and control sites. The circumference of the lower leg around the two excitation and measuring electrodes was measured. Then the cole-cole curve fitting was performed to calculate the Ri and Re, as well as the intracellular fluid resistivity (ρi) and extracellular fluid resistivity (ρe) of the ST and GB meridians, the related muscles and interspace lateral to ST or GB (ST/GB) meridians at the same level. RESULTS: The Ri and Re (Ω) values of the ST, GB, the muscle lateral to ST/GB and the interspace lateral to ST/GB were 19.1±1.3 and 28.3±1.4, 15.8±1.9 and 25.7±2.0, 19.6±1.3 and 31.3±1.6, and 19.4±1.2 and 32.4±1.6, respectively. The Re values were significantly lower at the ST and GB meridians than at the muscle lateral to and the interspace lateral to both meridians (P<0.05). The ρi and ρe values (Ω•cm) of the ST, GB, the muscle lateral to and the interspace lateral to ST/GB were 658.9±78.5 and 953.8±75.3, 528.0±90.1 and 833.9±101.7, 669.9±71.8 and 1 059.8±86.0, 655.9±64.8 and 1 099.3±93.3, respectively. The ρi and ρe values were significantly lower at the GB Meridian Than at the other three locntions, and the ρe value of ST Meridian was significantly lower than those of the muscle lateral to and the interspace lateral to ST/GB meridians (P<0.01)．. CONCLUSION: The Ri, Re, ρi and ρe values of the ST and GB meridians are significantly lower than those of their neighboring tissues at the same levels of the lower leg, suggesting a more extracellular fluid in the meridian running course and providing evidence for our speculation that the meridian is a hydraulic resistance channel.

Understanding Qi Running in the Meridians as Interstitial Fluid Flowing via Interstitial Space of Low Hydraulic Resistance.

Qi, blood and the meridians are fundamental concepts in Chinese medicine (CM), which are components of the human body and maintain physiological function. Pathological changes of qi, blood and meridians may lead to discomfort and disease. Treatment with acupuncture or herbal medicine aims to regulate qi and blood so as to recover normal function of the meridians. This paper explores the nature of qi as well as compares and correlates them with the structures of the human body. We propose a conceptualization of qi as being similar to the interstitial fluid, and the meridians as being similar to interstitial space of low hydraulic resistance in the body. Hence, qi running in the meridians can be understood as interstitial fluid flowing via interstitial space of low hydraulic resistance.

[Preliminary Observation on Imbalance Degree of Blood Perfusion on the Twelve Yuan-source Points in Healthy Subjects].

OBJECTIVE: To lay a foundation for meridian diagnosis by measuring the blood perfusion (BP) on yuan-source points of twelve meridians and calculating the normal range of imbalance degree (IBD) of left and right meridian (IBD-LRM), IBD of exterior-interior meridian (IBD-EIM) and IBD of hand-foot of the same name meridians (IBD-HFM) in healthy subjects. METHODS: BP at yuan-source points of twelve meridians was measured on 31 healthy volunteers by a Laser Doppler Line Scanner (LDLS). BP distribution and IBD-LRM, IBD-EIM, IBD-HFM were calculated. RESULTS: (1) Of the twelve meridians, BP was almost equal between the left and right of the same meridian. The mean value of IBD-LRM was (0.8±7.0)%. The absolute value of IBD-LRM ranged from (13.2±12.0)% to (22.9±15.6)%, with the mean value of (16.2±4.1)%, the IBD of gallbladder meridian of foot-shaoyang was the highest. (2) Of the six pairs of exterior-interior meridians, five pairs manifested as the interior (yin) meridians being larger than the exterior (yang) meridians in BP. The mean value of IBD-EIM was (-11.4±10.4)%. The absolute value of IBD-EIM ranged from (16.6±12.1)% to (36.6±15.6)%,with the mean value of (25.2±8.0)%, the IBD between pericardium meridian of hand-jueyin and triple energizer meridian of hand-shaoyang was the highest. (3)All of the hand-foot of the same name meridians were found hand meridians being larger than foot in BP. The mean value of IBD-HFM was (38.8±18.2)%.The absolute value of IBD-HFM ranged from (34.4±20.9)% to (59.6±12.0)%, with the mean value of (43.8±13.3)%, and IBD between heart meridian of hand-shaoyin and kidney meridian of foot-shaoyin was the highest. (4) The order of IBD absolute value in BP was the same as transcutaneous CO2 emission (TCE) measured before, and their IBD-LRM absolute values were close to each other. However, the absolute values of IBD-EIM and IBD-HFM existed some differences. CONCLUSIONS: The IBD-LRM of the twelve yuan-source points in BP of healthy subjects is small and in a balance state, but IBD-EIM and IBD-HFM are relatively high.

Barcode ITS2: a useful tool for identifying Trachelospermum jasminoides and a good monitor for medicine market.

Trachelospermum jasminoides is commonly used in traditional Chinese medicine. However, the use of the plant's local alternatives is frequent, causing potential clinical problems. The T. jasminoides sold in the medicine market is commonly dried and sliced, making traditional identification methods difficult. In this study, the ITS2 region was evaluated on 127 sequences representing T. jasminoides and its local alternatives according to PCR and sequencing rates, intra- and inter-specific divergences, secondary structure, and discrimination capacity. Results indicated the 100% success rates of PCR and sequencing and the obvious presence of a barcoding gap. Results of BLAST 1, nearest distance and neighbor-joining tree methods showed that barcode ITS2 could successfully identify all the texted samples. The secondary structures of the ITS2 region provided another dimensionality for species identification. Two-dimensional images were obtained for better and easier identification. Previous studies on DNA barcoding concentrated more on the same family, genus, or species. However, an ideal barcode should be variable enough to identify closely related species. Meanwhile, the barcodes should also be conservative in identifying distantly related species. This study highlights the application of barcode ITS2 in solving practical problems in the distantly related local alternatives of medical plants.

Fetal central nervous system anomalies: comparison of magnetic resonance imaging and ultrasonography for diagnosis.

BACKGROUND: Evaluation of fetal central nervous system (CNS) agenesis by ultrasonography (US) is frequently limited, but magnetic resonance imaging (MRI) has its own advantages and is gaining popularity in displaying suspected fetal anomalies. The purpose of this study was to explore the value of MRI in detecting fetal CNS agenesis. METHODS: Thirty-four women (aged from 22 to 35 years, average 27 years) with complicated pregnancies (16 - 39 weeks of gestation, average 30 weeks) were examined with a 1.5 T superconductive MR unit within 24 hours after ultrasonography. Half-Fourier acquisition single-shot turbo spin-echo (HASTE) T(2)-weighted imaging (T(2)WI) sequence were performed in all patients, and fast low angle shot (FLASH) T(1)-weighted imaging (T(1)WI) sequence were applied sequentially in seven of them. Comparison of the results was made between the MRI and US findings as well as autopsy or postnatal follow-up MRI findings. RESULTS: The gyrus, sulcus, corpus callosum, thalamus, cerebellum, brainstem, and spinal cord of fetus were shown more clearly on T(2)-weighted MR images than on T(1)-weighted MR images. MRI corrected the diagnosis of US in 10 cases (10/34, 29.41%) and the diagnosis was missed only in 1 case (1/34, 2.94%). CONCLUSION: MRI has advantages to US in detecting fetal CNS anomalies and is a supplement to US in complicated pregnancies.
