ObjectiveTo investigate the expression of CCL2 and its effects on the proliferation and adhesiveness on leukemia cells in patients with acute lymphoblastic leukemia(ALL). MethodsThe bone marrow mesenchymal cells (BMMSC) and bone marrow mononuclear cells (BMMNC) of 30 ALL patients and 30 healthy controls were studied, and CCL2 level was evaluated by ELISA. CCL2 gene mRNA level in ALL was determined by RT-PCR. The cell proliferation and adhesiveness were detected by MTT assays. The cell counts were measured by flow cytometry. ResultsThe BM plasma levels of CCL2 in patients at diagnosis were significantly higher than that in healthy controls [(780.12±129.61) pg/ml vs (120.49±25.21) pg/ml,t =4.96, P =0.00]. Supernatant levels of CCL2 in BMMSC were significantly higher than that of BMMNC [(572.38±35.39) pg/ml vs (193.85±15.45) pg/ml,t =5.37,P =0.00]in vitro.CCL2 cannot induce leukemia proliferation alone,but could induce leukemia proliferation in BMMNC and BMMSC co-culture in a dose- and time-dependent manner.CCL2 could increase the leukemia adhesive to the BMMSC compared with control (r =0.824,P =0.02).ConclusionPatients with B type ALL had higher levels of CCL2 which was secreted by BMMSC. The leukemia could induce the BMMSC to secrete CCL2. CCL2 could promote the survival and proliferation of leukemia in the presence of BMMSC and BMMNC, and enhance ALL cells adhesion toBMMSC in a dose-dependent manner.

The animal models used in the experimental research of Traditional Chinese Medicine (TCM) to prevent and treat T2DM are mainly spontaneous and induced. The experimental research of TCM in the prevention and treatment of type 2 diabetes can be divided into Chinese medicine compound, Chinese medicine and its extract, Chinese medicine monomer. The mechanism is mainly through regulating intestinal flora, increasing insulin content, lowering blood sugar, lowering blood lipids, improving glucose tolerance, and improving gluconeogenesis, antioxidant, inhibit cell apoptosis, etc. play the role of preventing and treating T2DM in multiple links and multiple targets.

This study was aimed to explore the curative effect of Zhuo-Du-Qing (ZDQ) particles on diabetic cystopa-thy (DCP) based on the theory of turbid toxin. A total of 100 DCP patients were randomly divided into the control group with 47 cases and the treatment group with 53 cases. Mecobalamin tablets was given in the control group. And ZDQ particles were given to the treatment group. The treatment course was 3 months. The observation was made on the bladder residual urine (BRU), clinical manifestation integral, hemodynamic indexes, HOMA-IR and HbA1c before and after the treatment. The results showed that compared with pretreatment, the BRU, clinical manifestation integral, hemodynamic indexes, and HOMA-IR were significantly reduced (P < 0.01). Compared with the control group, the BRU, clinical manifestation integral, hemodynamic indexes, and HOMA-IR were also significantly reduced (P <0.01). The effective rate in the treatment group was 81.1%, which was significantly higher than 59.6% in the control group (P< 0.05). There were no obvious changes on the blood routine examination, urine routine examination, stool routine examination, liver function, renal function, electrocardiogram and so on before and after treatment. It was con-cluded that the treatment of DCP with ZDQ particles was safe and effective. To remove toxin and descend turbid may be another effective treatment method for DCP. The occurrence and development of DCP were closely related to the turbid toxin.

Objective To analyze crossed cerebellar diaschisis(CCD) after subacute phase of spontaneous cerebral hemorrhage(SPSCH)and it's relevant factors with whole-brain CT perfusion(CTP) imaging. Methods Eighty-six patients diagnosed with unilateral SPSCH by CT were prospectively enrolled in our study from July 2015 to October 2016. Whole-brain CTP was performed in each patient.Cerebral blood flow(CBF), cerebral blood volume(CBV), mean transit time(MTT)and time-to-peak(TTP) inipsilateral and contralateral cerebellum were manually measured.The asymmetric indexs(AIs) were also calculated. Moreover, the volume of hematoma, the maximumarea of peri-hematomahypoperfusionin CBF and clinical factors(age, gender, time intervals from symptom onset)were analyzed,and NIHSS scores were used to evaluate the neurological status before patient admission, inspection, and discharge.CCD was rated positive when a unilateral supratentorial hematomawas appeared and an accompanying perfusion decrease was showed in the contralateral cerebellum on at least two sequential slices of CTP maps.All the individuals were divided into two groups including CCD-positive groupand CCD-negative group. The perfusion parameters (CBF, CBV, MTT, and TTP)between the contralateral and ipsilateral cerebellum were analyzed by the two-tailed paired t-test in CCD-positive group. The differences in the perfusion and clinical variables between the two groups were analyzed by the independent sample t-test and the Chi-squared test. Therelationships between the AI values and clinical or radiologic variables were assessed with Pearson correlation test. Results We found 35 CCD positive cases and 51 negative cases in the 86 patients.In CCD-positive groups, the perfusion values of cerebellumipsilateral and contralateral to the hematomawere as follows:CBF were (40.88±11.23) vs. (33.91±9.96) ml·100 g-1·min-1, CBV were (3.30±1.18) vs. (2.75±1.13) ml/100 g and TTP were (22.09±3.98) vs. (22.88±4.15) s, respectively, and there was statistical significance (t=10.231,8.223,-2.883,P<0.05).In CCD positive group, CBF, CBV, TTP, and MTT of the contralateral cerebellar hemisphere was changed in 35, 32, 26, and 16 cases,respectively.The AI value of CBF(AICBF)in CCD-positive group was (17.10±9.10)%, which was higher than that in the negative group (-0.95±17.01)%, there was statistical significance(t=6.367,P<0.05).The AI value of CBV(AICBV)was (17.43 ± 11.65)% in CCD-positive group, also significantly higher than that in negative group which was (1.55±21.06)%(t=4.477, P<0.05). No statistical difference(P>0.05)was found in hematoma location,hematoma volume, supratentorialhypoperfusion area and NIHSS scores(at admission, inspection)between CCD-positive and negative groups.The AICBF and AITTP showed linear correlation with time intervals in CCD-positive patients(P<0.05). Conclusions CCD is a common phenomenon in patients with SPSCH.Of all the perfusion parameters,CBF abnormalities are more common.The severity of CCD has a certain correlation with time intervals.There is no significant correlation between CCD and the clinical or radiological data(age, NIHSS scores,hematoma volume, and supratentorial hypoperfusion area).

Objective: This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder. Methods: Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration. Results: The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week. Conclusion PMTS is safe and effective in improving insomnia disorders.

Hydroxy amino acids, constituents of chiral pharmaceutical intermediates or precursors, have a variety of unique functions in the research fields of biotechnology and molecular biology, i.e. antifungal, antibacterial, antiviral and anticancer properties. Biosynthesis of hydroxy amino acids is preferred because of its high specificity and selectivity. The hydroxylation of hydrophobic amino acids is catalyzed by hydroxylase, which belongs to the mononuclear non-heme Fe(Ⅱ)/α-ketoglutarate-dependent dioxygenases (Fe/αKGDs). Fe/αKGDs utilize an (Fe(Ⅳ)=O) intermediate to activate diverse oxidative transformations with key biological roles in the process of catalytic reaction. Here, we review the physiological properties and synthesis of hydroxy amino acids, especially for the 4-HIL and hydroxyproline. The catalytic mechanism of Fe/αKGDs is elucidated, and the applications of hydroxy amino acids in industrial engineering are also discussed.

Glycyrrizae Radix et Rhizoma has high medicinal value and is widely used in compatibility. It is used most frequently in the compatibility of Chinese medicine prescriptions，and is known as ''Guolao''（national medicine） and "master of all medicines". The characteristic active ingredients are mainly liquitin，glycyrrizic acid，glycyrrizin，and licochalcone. In different compatibilities，based on traditional and modern pharmacological theories，the corresponding effect of Glycyrrizae Radix et Rhizoma are brought into play through different mechanisms. Based on the traditional pharmacology of Glycyrrizae Radix et Rhizoma for tonifying spleen，replenishing Qi，clearing heat，removing toxin，dispelling phlegm，relieving cough and pain，and harmonizing various medicines，this paper used herbal authentication to analyze its compatibility application and mechanism. It was found that Glycyrrizae Radix et Rhizoma played corresponding effect in compatibilities through "tonification"，"harmonization"，and "regulation". For example，Glycyrrizae Radix et Rhizoma was combined with tonics including Ginseng Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma to tonify the five Zang-organs through its strong tonifying effect，combined with Paeoniae Radix Alba and Aconiti Lateralis Radix Praeparata to relieve emergencies and pains through harmonizing medicine power and properties，and combined with Rhei Radix et Rhizoma and Natrii Sulfas to reduce medicine intensity through regulating medicine properties and body characteristics. The application law and mechanism of the modern pharmacological compatibility of Glycyrrizae Radix et Rhizoma were analyzed by data mining and network pharmacology. It was found that the modern clinical formula was often compatible with Glycyrrizae Radix et Rhizoma for anti-inflammation，cardiovascular and cerebrovascular protection，anti-virus，and anti-tumor，Ephedrae Herba and Scutellariae Radix for anti-inflammation，Bambusae Caulis in Taenias，Salviae Miltiorrhizae Radix et Rhizoma，and Aurantii Fructus Immaturus for cardiovascular and cerebrovascular protection，and Ophiopogonis Radix and Chuanxiong Rhizoma for nerves protection. Meanwhile，the important targets of the characteristic ingredients were protein kinase B1 （Akt1），interleukin-6 （IL-6），tumor necrosis factor （TNF），and epidermal growth factor receptor （EGFR）. The important characteristic pathways such as tyrosine kinase inhibitor resistance pathway and cyclic guanosine monophosphate （cGMP）/protein kinase G （PKG） signal pathway played the role of cardiovascular and cerebrovascular protection，and proteoglycan pathway in cancer played a neuroprotective role. This study is expected to provide references for the rational compatibility and application of Glycyrrizae Radix et Rhizoma，as well as the compatibility application of Chinese medicine prescriptions.
