The antidepressant activity and molecular mechanisms of Yueju Wan volatile oil were investigated. The Yueju Wan volatile oil was extracted by using supercritical CO_2. Gas chromatography-mass spectrometry(GC-MS) combined with network pharmacology identified 28 chemical constituents in Yueju Wan volatile oil, primarily terpenes and lactones. A total of 123 overlapping targets were associated with depression, including core targets of interleukin-1β(IL-1β), signal transducer and activator of transcription 3(STAT3), and caspase-3(CASP3). These targets were mainly involved in the prolactin, advanced glycation end products/receptor(AGE/RAGE), and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathways. A reserpine-induced depression mouse model was established to evaluate the therapeutic effects and mechanisms of Yueju Wan volatile oil. The effects of Yueju Wan volatile oil on depression-like behavior in mice were evaluated by analyzing body mass, body temperature index, tail suspension immobility time, forced swimming immobility time, and sucrose preference. Hematoxylin-eosin(HE) staining revealed neuronal protection of Yueju Wan volatile oil in the brain of mice. Enzyme-linked immunosorbent assay(ELISA) and Western blot were employed to detect the protein expression of AGEs, IL-1β, phosphorylated PI3K(p-PI3K), Akt, phosphorylated Akt(p-Akt), nuclear factor κB(NF-κB), and brain-derived neurotrophic factor(BDNF). Behavioral evaluation showed that Yueju Wan volatile oil could effectively control the decline of body mass and body temperature of depressed mice, reduce tail suspension and swimming immobility time, and enhance their preference for sucrose. Histopathological examination showed that Yueju Wan volatile oil could alleviate the neuronal damage in CA1 and dentate gyrus(DG) of the hippocampus of mice. ELISA and Western blot results showed that Yueju Wan volatile oil could significantly increase the protein expression levels of PI3K, Akt, and BDNF and significantly decrease the protein expression levels of AGEs, IL-1β, p-PI3K, p-Akt, and NF-κB in the hippocampus of mice. Furthermore, the p-PI3K/PI3K and p-Akt/Akt ratios were significantly decreased at medium and high doses. These findings suggest that the aromatherapy of Yueju Wan volatile oil can significantly improve reserpine-induced depression-like behavior in mice, which may be related to reducing the expression of neuronal membrane protein AGEs, reducing the phosphorylation levels of PI3K and Akt, inhibiting NF-κB entry into the nucleus, and alleviating the release of pro-inflammatory factors and nerve injury.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Bone-turnover marker (BTM) measurements in the blood or urine reflect the bone-remodeling rate and may be useful for studying and clinically managing metabolic bone diseases.Substantial evidence supporting the diagnostic use of BTMs has accumulated in recent years, together with the publication of several guidelines. Most clinical trials and observational and reference-interval studies have been performed in the Northern Hemisphere and have mainly involved Caucasian populations. This review focuses on the available data for populations from the Asia-Pacific region and offers guidance for using BTMs as diagnostic biomarkers in these populations. The procollagen I N-terminal propeptide and β-isomerized C-terminal telopeptide of type-I collagen (measured in plasma) are reference BTMs used for investigating osteoporosis in clinical settings. Premenopausal reference intervals (established for use with Asia-Pacific populations) and reference change values and treatment targets (used to monitor osteoporosis treatment) help guide the management of osteoporosis. Measuring BTMs that are not affected by renal failure, such as the bone-specific isoenzyme alkaline phosphatase and tartrate-resistant acid phosphatase 5b, may be advantageous for patients with advanced chronic kidney disease. Further studies of the use of BTMs in individuals with metabolic bone disease, coupled with the harmonization of commercial assays to provide equivalent results, will further enhance their clinical applications.

Background: Calibration is a critical component for the reliability, accuracy, and precision of mass spectrometry measurements. Optimal practice in the construction, evaluation, and implementation of a new calibration curve is often underappreciated. This systematic review examined how calibration practices are applied to liquid chromatography-tandem mass spectrometry measurement procedures. Methods: The electronic database PubMed was searched from the date of database inception to April 1, 2022. The search terms used were “calibration,” “mass spectrometry,” and “regression.” Twenty-one articles were identified and included in this review, following evaluation of the titles, abstracts, full text, and reference lists of the search results. Results: The use of matrix-matched calibrators and stable isotope-labeled internal standards helps to mitigate the impact of matrix effects. A higher number of calibration standards or replicate measurements improves the mapping of the detector response and hence the accuracy and precision of the regression model. Constructing a calibration curve with each analytical batch recharacterizes the instrument detector but does not reduce the actual variability. The analytical response and measurand concentrations should be considered when constructing a calibration curve, along with subsequent use of quality controls to confirm assay performance. It is important to assess the linearity of the calibration curve by using actual experimental data and appropriate statistics. The heteroscedasticity of the calibration data should be investigated, and appropriate weighting should be applied during regression modeling. Conclusions This review provides an outline and guidance for optimal calibration practices in clinical mass spectrometry laboratories.

Functional reference limits describe key changes in the physiological relationship between a pair of physiologically related components. Statistically, this can be represented by a significant change in the curvature of a mathematical function or curve (e.g., an observed plateau). The point at which the statistical relationship changes significantly is the point of curvature inflection and can be mathematically modeled from the relationship between the interrelated biomarkers. Conceptually, they reside between reference intervals, which describe the statistical boundaries of a single biomarker within the reference population, and clinical decision limits that are often linked to the risk of morbidity or mortality and set as thresholds. Functional reference limits provide important physiological and pathophysiological insights that can aid laboratory result interpretation. Laboratory professionals are in a unique position to harness data from laboratory information systems to derive clinically relevant values. Increasing research on and reporting of functional reference limits in the literature will enhance their contribution to laboratory medicine and widen the evidence base used in clinical decision limits, which are currently almost exclusively contributed to by clinical trials. Their inclusion in laboratory reports will enhance the intellectual value of laboratory professionals in clinical care beyond the statistical boundaries of a healthy reference population and pave the way to them being considered in shaping clinical decision limits. This review provides an overview of the concepts related to functional reference limits, clinical examples of their use, and the impetus to include them in laboratory reports.

Kaixinsan recorded in an ancient medical book named Beiji Qianjin Yaofang is one of the famous classical formula，which is one of the common prescriptions used by ancient physicians to treat amnesia. In the process of using this prescription，later generations of physicians derived many kinds of associated prescriptions. The effect and indications of these prescription have been inherited and expanded from those in the Beiji Qianjin Yaofang because of the changes in dosages. Therefore，it is necessary to verify the effect and indications of the formulas and the rules of dosage changes. The research results showed that its basic effects included to nourish the mind，induce resuscitation，strengthen the spleen and calm the mind，and keep balance between heart-Yang and kidney-Yin. The main indications included amnesia，sorrow and sadness，fright and fear，and so on，which may differ slightly in different dynasties. In Song，Jin and Yuan dynasties，it also demonstrated the effect of warming the heart and Yang，clearing away heat and relieving wind besides the basic effects， with basically the same indications （slightly different from those in previous dynasties）. In Ming dynasty，it demonstrated the effect of nourishing Yin，clearing away heat and nourishing blood besides the basic effects，and the indications expanded to farsightedness，nearsightedness，spermatorrhea and blurred urine. In the Qing dynasty，its effect also included to nourish the heart and kidney on the basis of the Ming dynasty，and the indications were basically the same with those in the previous dynasties. The compatibility ratio of ancient physicians in the application of this prescription and its associated prescriptions showed some remarkable features，for example，Ginseng Radix et Rhizoma and Poria should be increased and their ratio was≈1∶1 in the treatment of amnesia，sorrow，sadness，fright，fear，farsightedness，spermatorrhea and blurred urine，with ratio of Polygalae Radix to Acori Tatarinowii Rhizoma≈1∶1； the dosage of Polygalae Radix and Acori Tatarinowii Rhizoma should be increased in the treatment of nearsightedness，and their ratio was≈1∶1. The compatibility ratio of Polygalae Radix-Ginseng Radix et Rhizoma-Poria-Acori Tatarinowii Rhizoma=2∶3∶3∶2 was the most frequent，which basically included the indications of this prescription and its associated prescriptions. According to statistics，the average dosages that ancient physicians used were significantly higher than those in the modern times，Polygalae Radix 57 g，Ginseng Radix et Rhizoma 62 g，Poria 70 g，and Acori Tatarinowii Rhizoma 54 g，respectively in ancient times，while Polygalae Radix 11 g，Ginseng Radix et Rhizoma 15 g，Poria 17 g，and Acori Tatarinowii Rhizoma 9.5 g，respectively in modern times. The above textual research results can provide some reference for preparation of tradition Chinese medicine products of Kaixinsan.

The classical prescription Kaixinsan，which is recorded in an ancient medical book named Beiji Qianjin Yaofang，is one of the famous prescriptions used by ancient physicians to treat amnesia. Research on classical prescriptions has attracted more and more attention from scientific research institutions and related enterprises. Based on ancient books，textual research on origins and development of prescriptions，combing the evolution of prescriptions，preparations，oral ways，taboos and others are the important contents of the study on classical prescriptions. The research results show that the creation of Kaixinsan in Beiji Qianjin Yaofang can be traced back to Kaixinsan recorded in Jiyanfang and Dingzhiwan recorded in Gujinluyanfang. Later generations of physicians created many associated prescriptions in the process of applying Kaixinsan，and the efficacy of these prescriptions was constantly expanded with the development of the times. In the Tang and Song dynasties，Kaixinsan and its associated prescriptions were mainly used to treat amnesia，sorrow，fear，and other diseases. In the Jin and Yuan dynasties，these prescriptions were also used to treat convulsions and yawning. In the Ming dynasty， they were mainly for the treatment of hyperopia， myopia， sprematorrhea，and constipation. In the Qing dynasty，these herbs could be used to treat auricular deafness， aging and sweating. The dosage of Ginseng Radix et Rhizoma and Poria should be increased in the treatment of farsightedness，spermatorrhea and blurred urine，and in the treatment of nearsightedness，the dosage of Polygalae Radix and Haliotidis Concha should be increased. The main pathogenesis of the disease that Kaixinsan and its associated prescriptions treated could be summarized as the deficiency of heart and spleen，imbalance between heart-Yang and kidney-Yin，and the internal resistance of phlegm stagnation. By summarizing the contents of the preparation of tradition Chinese medicine products for Kaixinsan and its associated prescriptions，it is suggested that the dosage form of Kaixinsan can be pills，with the specification size confroming to the most record of ancient generations of physicians，as big as Firmiana platanifolia's fruit.The volume of a single pill is about 0.25 mL and the weight is about 0.3 g. The initial dosage is fifteen pills，which can be modified according to the severity of the illness，with no more than forty pills for each time，three times a day. Also，some excitant food like the sour food，sweet food and mutton should be avoided during the medication. The above research results can provide literature basis for the development of compound tradition Chinese Medicine preparation of Kaixinsan.

Objective To study the clinical characteristics and biochemical parameters of diabetic nephropathy patients , and to understand the occurrence of chronic complications such as kidney diseases. Methods From February 1, 2017 to November 30, 2020, 352 patients with type 2 diabetes aged between 35 and 70 years with diabetes lasting more than 10 years were selected for study. According to the estimated glomerular filtration rate (EGFR), the patients were divided into two groups, in which the patients with EGRF were less than 15mL/min/1.73m2, and they suffered from ESRD and underwent hemodialysis. The subjects in the second group were reclassified into three groups according to their urinary albumin excretion, including microalbuminuria, massive albuminuria and end-stage renal disease (ESRD). To analyze the hematological and biochemical parameters in different stages of diabetic nephropathy. Results Among 232 patients with nephropathy, 96 cases (41.38%) had microalbuminuria, 43 cases (18.53%) had albuminuria and 91 cases (39.22%) had end-stage renal disease (ESRD).The remaining 120 patients (34.09%) did not develop nephropathy. Patients with kidney disease are older, with an average age (SD) of 55.62 6.00 years, and diabetes lasts longer (19.04 6.33 years). The BMI of patients with kidney disease is lower than that of patients without kidney disease. Among them, insulin resistance, elevated uric acid level, low red blood cell count and low hemoglobin level are related to the significantly increased risk of albuminuria and ESRD. Elevated levels of uric acid and LDH are associated with significantly increased risk of microalbuminuria and ESRD, while elevated red blood cell distribution width is associated with significantly increased risk of ESRD. Conclusion Diabetic nephropathy is related to insulin resistance, changes of liver enzymes and uric acid, as well as abnormal red blood cell count and red blood cell shape, which need to be monitored frequently by diabetic nephropathy patients.

Objective To study the genetic polymorphism of whole mitochondrial DNA （mtDNA） genomes in She population in Zhejiang and to explore the maternal genetic structure of the She population. Methods Whole mtDNA genomes of 231 unrelated individuals from She population in Zhejiang Province were sequenced. The number of mutations and population genetics parameters such as, the haplotype diversity （HD）, discrimination power （DP）, and random match probabilities （RMP） were analyzed. The mtDNA haplogroups of Zhejiang She population were classified, and the maternal genetic relationships between She and nine other Chinese populations were estimated. Results In 231 Zhejiang She samples, 8 507 mutations （702 types） were observed and the samples were classified into 94 haplogroups. The HD, DP and RMP values were 0.998 6, 0.994 2 and 0.005 8, respectively. The lowest genetic differentiation degree （F_st=0.006 89） was detected between Zhejiang She population and southern Han population. Principal component analysis （PCA） and median-joining network analysis showed that the genetic distance of Zhejiang She population with Guangxi Yao, Yunnan Dai and Southern Han populations was relatively close, but the population still had some unique genetic characteristics. Conclusion The whole mtDNA genomes are highly polymorphic in Zhejiang She population. The Zhejiang She population contains complex and diverse genetic components and has a relatively close maternal genetic relationship with Guangxi Yao, Yunnan Dai and Southern Han populations. Meanwhile, Zhejiang She population has kept its unique maternal genetic components.
