ABSTRACT
italic>Gentiana crassicaulis Duthie ex Burk. is one of the plant sources of Gentianae Macrophyllae Radix (QinJiao). Gentiana tibetica King ex Hook. f. and Gentiana robusta King ex Hook. f. are relative species of G. crassicaulis. Due to the large intraspecific morphological variation, G. crassicaulis showed high morphological similarity with G. tibetica and G. robusta. And the distribution area of the three species overlaps to some extent, which makes it difficult to identify them. On the basis of morphological identification, the method of molecular identification of the three species was constructed in this study based on chloroplast genomes. The chloroplast genome of Gentiana tibetica is 148 765bp long, with LSC, SSC and IR 81 163 bp, 17 070 bp and 25 266 bp, respectively. The structure of the three is consistent. The chloroplast genome sequences of G. tibetica and G. crassicaulis are highly similar, and the number of variable sites is 9 (149 267 bp in total). Diagnostic SNP that could effectively identify the three species was screened and verified, and a dual-peak SNP detection method was established for the effective identification of each species and mixed samples. Our study provides basic data for the molecular identification of G. crassicaulis and its related species, and the arrangement of related Tibetan medicine.

ABSTRACT
Objective:To evaluate the effects of a booster immunization with a candidate tetanus toxoid, reduced diphtheria toxoid and acellular pertussis combined vaccine (Tdap) in a rat model after primary vaccination with diphtheria, tetanus, acellular pertussis and Sabin strain inactivated poliovirus combined vaccine (DTacP-sIPV) or diphtheria, tetanus, acellular pertussis, inactivated poliovirus and haemophilus type b combined vaccine (DTacP-IPV/Hib) for further preclinical study.Methods:Wistar rats were randomly divided into three groups and respectively immunized with a self-developed DTacP-sIPV, a marketed DTacP-IPV/Hib and normal saline at 0, 1, and 2 months of age. Serum levels of antibody against each component in each group were detected before immunization and after each dose. A booster dose of the candidate Tdap was given 10 months after primary immunization. Serum levels of antibody against each component in each group were detected before, 1 month and 6 months after the booster immunization.Results:One month after three doses of primary immunization, the geometric mean titers (GMT, Log2) of antibodies against diphtheria toxoid (DT), tetanus toxoid (TT), pertussis toxin (PT), filamentous hemagglutinin (FHA) and pertactin (PRN) in the DTacP-sIPV group were 17.41, 18.34, 18.11, 19.93 and 13.91, respectively, and the seroconversion rates of these components all reached 100%. Ten months after primary immunization, the GMTs of antibodies against DT, TT, PT, FHA and PRN decreased to 15.17, 14.26, 13.60, 14.51 and 10.39, respectively, and the seroconversion rates remained above 89%. One month after booster immunization, the GMTs of antibodies against DT, TT, PT and FHA in the DTacP-sIPV and DTacP-IPV/Hib groups were 16.49/17.26, 16.80/17.63, 16.70/17.74 and 18.48/19.26, respectively, and the seroconversion rates of these components all reached 100% with no significant difference between the two groups ( P>0.05). The GMTs of anti-PRN antibody in the DTacP-sIPV and DTacP-IPV/Hib groups were 13.07 and 11.00, and the seroconversion rates were 100% and 88%, which were higher in the DTacP-sIPV group than in the DTacP-IPV/Hib group ( P<0.05). Six months after booster immunization, the GMTs of antibodies against DT, TT, PT, FHA and PRN in the DTacP-sIPV and DTacP-IPV/Hib groups decreased to 15.74/14.87, 15.07/15.14, 14.84/15.73, 16.62/16.37 and 11.44/9.96, respectively, and the seroconversion rates remained above 88%. Conclusions:Booster vaccination with the candidate Tdap vaccine induces humoral immune response following primary immunization with DTacP-sIPV or DTacP-IPV/Hib in the Wistar rat model, while the antibody titer decreases with time.
ABSTRACT
OBJECTIVE@#To investigate the effect of norcantharidin (NCTD) to proliferation of leukemia cells through disrupting key regulators of sonic Hedgehog (SHH) pathway and its downstream transcription factor SOX2.@*METHODS@#CCK8 was used to detected the HL60 and NB4 cells after inhibited by NCTD, SMO and GLI1 inhibitor for 24 hours. Expression level of SMO, GLI1 and SOX2 in HL60 cells with NCTD treatment was detected by immunoblot. HL60 cells were transfected with pcDNA3.1 plasmid expressing GLI1 or SOX2. Empty vector and pcDNA3. 1-EGFP were divided into negative and positive control group, respectively. The expression of exogenous GLI1 or SOX2 in HL60 cells was confirmed by immunoblot, and growth curve of HL60 cell was checked by CCK8. Proliferation of genetic modified HL60 cells treated by various dose of NCTD was detected.@*RESULTS@#NCTD, SMO/GLI1 inhibitors could inhibit the proliferation of NB4 and HL60 cells in a dose-dependent manner. Compared with solvent (DMSO)-treated control group, NCTD remarkably decreased protein level of SMO, GLI1 and SOX2. GLI1 and SOX2 were overexpressed in HL60 cells as compared with pcDNA3.1 empty vector-transfected group. Growth curve demonstrated significant proliferative advantage of GLI1/SOX2-transfected cells. CCK8 assay indicated that GLI1/SOX2-overexpressed HL60 cells were more resistant to NCTD treatment.@*CONCLUSION@#NCTD attenuates HL60 proliferation via targeting the Hedgehog/SOX2 axis.

Objective:To report our experience in treatment of patients with orthopaedic trauma during COVID-19 epidemic.Methods:We retrospectively analyzed the 67 patients with orthopedic trauma who had been treated at Department of Orthopaedics, Peking Union Medical College Hospital from February 1 to March 31, 2020. After screening for COVID-19 infection was performed under strict protection, the patients were diagnosed and assigned to outpatient emergency treatment or hospitalization according to their specific condition. Twenty-six patients were treated at the outpatient emergency department. They were 8 males and 18 females with an average age of 69.5 years. Of them, 6 with vertebral compression fracture were placed on bed brakes, 14 with limb fracture immobilized after close reduction, 2 with skin laceration treated with debridement and suture, and 4 with hip fracture immobilized in bed. In the 41 hospitalized patients, there were 14 males and 27 females with an average age of 68.5 years. In them, hemiarthroplasty was performed for 7 femoral neck fractures, kyphoplasty for 5 vertebral compression fractures, total elbow arthroplasty for one humeral intercondylar fracture, exploration and suture for one case of Achilles tendon rupture, and internal fixation surgery for the remaining 27 cases.Results:Most of the patients had osteoporotic fractures which accounted for 61.5% (16/26) of the outpatients and 68.3% (28/41) of the inpatients, respectively. The duration from injury to surgery averaged 2.3 days and the length of hospitalization 4.5 days for the 41 hospitalized patients, decreased compared with the corresponding data (3.1 days and 11.5 days) for the similar inpatients in the same period last year. In the 41 inpatients, fever was observed upon hospitalization in 4 cases and after operation in 26 cases, and related to their primary injury or surgical trauma in all. Acute pulmonary embolism happened during operation in one patient with femoral shaft fracture.Conclusions:The prevention and control of COVID-19 should be continued. The awareness and behavior of health care providers are expected to be enhanced by strict screening protocol, protection and supervision. The proportion of elderly patients with osteoporotic fracture increased during the COVID-19 pandemic. Shortage of blood was the major problem affecting the treatment. Timely surgical treatment should be indicated for the patients with orthopedic trauma, especially those with lower extremity fracture.

ABSTRACT
OBJECTIVE@#To compare the effect of acupoint injection and intramuscular injection with mouse nerve growth factor (mNGF) on gross motor function development of children with cerebral palsy (CP), and explore the treatment mechanism.@*METHODS@#A total of 63 children with CP were randomly divided into an observation group (32 cases, 4 cases dropped off ) and a control group (31 cases, 3 cases dropped off). Based on the routine rehabilitation therapy, the control group received intramuscular injection of mNGF(18 µg/2 mL), and the observation group received acupoint injection of mNGF at Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), Sanjiaoshu (BL 22), Shenting (GV 24), Baihui (GV 20), Fengfu (GV 16), Dazhui (GV 14), etc. Of them, 5-6 acupoints alternately were selected each time, and each acupoint was given 0.3-0.5 mL, totally 18 µg/2 mL. Both treatment were carried out once every other day for six months. Before and after treatment, the children's development of brain function was assessed using gross motor function classification system (GMFCS). Before treatment (T), after 2 (T), 4 (T) and 6 (T) months of treatment, the motor function was evaluated by gross motor function measure (GMFM-88). The systolic peak velocity (Vs), mean velocity (Vm) and vascular resistance index (RI) of anterior cerebral artery (ACA) and middle cerebral artery (MCA) were measured, and the level of N-acetyl aspartate acid (NAA), choline (Cho), lactate (Lac) and creatine (Cr) from the basal ganglia, thalamus and periventricular white mater were detected by magnetic resonance spectroscopy (MRS) technology with MAGNETOM Skyra3.0T magnetic resonance imaging system before and after treatment.@*RESULTS@#Compared with before treatment, the GMFCS classification of the observation group after treatment was significantly improved (0.05), however, the observation group had a 3.142 times of feasibility for good gross motor function development by more than level 1 compared to the control group (<0.05). After 2, 4, and 6 months of treatment, the GMFM-88 scores of the two groups showed an upward trend (<0.01), and the increase of the observation group was greater than that of the control group (<0.05). Compared with before treatment, in the ACA and MCA, the Vs and Vm increased, RI decreased in both groups after treatment (<0.01), and in the brain, NAA/Cr increased, Cho/Cr and Lac/Cr decreased (<0.01), and after treatment, the Vs, Vm of ACA and MCA and NAA/Cr of brain in the observation group were higher than those in the control group (<0.05), and the RI of ACA and MCA and Cho/Cr and Lac/Cr of brain in the observation group were lower than those in the control group (<0.05).@*CONCLUSION@#The mNGF acupoint injection has a better effect on the gross motor function in the children with cerebral palsy compared with the intramuscular injection, and the mechanism may be associated with exhibiting the double effects of acupoint effect and the targeting therapy of drug, which can effectively improve the cerebral hemodynamics and the metabolism of cerebral nervous substances.
ABSTRACT
Cardiac glycoside is a class of steroidal glycosides with significant physiological activities to the heart. Several drugs had been approved for the treatment of heart failure and atrial fibrillation. In recent studies, the researchers have found that cardiac glycoside can selectively inhibit the proliferation of human tumor cells and has potent antitumor efficacy. Unfortunately, the poor solubility and severe adverse effects of cardiac glycoside hindered further clinical application in the field of anticancer. It is an effective strategy to solve the "drug-like" problem of cardiac glycoside by changing the pharmacokinetics and distribution in vivo and reducing the dosage and side effects by virtue of modern preparations technology and treatment scheme. In this review, a brief introduction of the developmental course and mechanism of cardiac glycosides in anticancer field was made, and recent research progress of cardiac glycosides preparations were summarized and discussed. Finally, the further research direction was prospected.

Objective: To prepare dihydromyricetin (DMY) phospholipids complex (DMY-PC) and its nanostructured lipid carriers (DMY-PC-NLC), and carry out in vitro and in vivo evaluation. Methods: DMY-PC was prepared by solvent evaporation method. High pressure homogenization method was used to prepare DMY-PC-NLC. Orthogonal test was employed to optimize the ratio of solid/liquid lipid, dose of lipids materials, dose of DMY-PC and the concentration of emulsifier of poloxamer. The lyophilized powder of DMY-PC-NLC was prepared with 5% of mannitol as protective agent. The comparation of in vitro release and pharmacokinetics between DMY-PC and DMY-PC-NLC was also studied. Results: DMY was in an amorphous state in DMY-PC. The results of 1HNMR showed that the structure of DMY was not changed. The optimized prescription of DMY-PC-NLC determined by orthogonal test was as follow: The ratio of solid/liquid lipid was 5:1, dose of lipids materials was 325 mg, dose of DMY-PC was 45 mg and the concentration of emulsifier of poloxamer was 0.9%. The average size, Zeta potential, entrapment efficiency and drug loading of DMY- PC-NLC was (197.25 ± 4.42) nm, (-18.2 ± 2.1) mV, (71.68 ± 1.36)% and (3.94 ± 0.24)%, respectively. The in vitro release model was accord with Weibull model and the equation was lnln(1-Mt/M∞)=0.700 1 lnt-1.954 1 (r = 0.971 4). The relative bioavailability of DMY-PC and DMY-PC-NLC were enhanced to 1.63 and 3.22 times compared to DMY, respectively. Conclusion: Compared with DMY-PC, the absorption was promoted by DMY-PC-NLC in further, and the bioavailability of DMY was enhanced effectively.

ABSTRACT
OBJECTIVE:To study the preventive effect of resveratrol on model mice and improvement effect on model golden hamsters (shorter for hamsters) with hyperlipidemia. METHODS:Hyperlipidemia animal models were induced by using high-fat and high-cholesterol diet. Mice and hamsters were both randomly divided into model group and resveratrol low-dose, medi-um-dose,high-dose groups(40,80,160 mg/kg for mice,25,50,100 mg/kg for hamsters),10 in each group. 10 corresponding animals were selected as normal control group. Except that normal control group was fed normal diet and intragastrically administrat-ed normal saline,other mice were intragastrically administrated relevant medicines when fed high-fat and high-cholesterol diet;oth-er hamsters were firstly modeled for 2 weeks and intragastrically administrated relevant medicines after modeling. High-fat and high-cholesterol diet was fed during administration. It was administrated for 4 weeks. Total cholesterol(TC)and low density lipo-protein cholesterol(LDL-C)levels in serum of mice and hamsters were detected every week. After 4 weeks,pre-protein converting enzyme subtilisin 9(PCSK9)mRNA and protein expression,microRNA-27a(miRNA-27a)expression in serum of mice and ham-sters,and low density lipoprotein receptor(LDLR)protein expression in liver tissue of mice were detected. RESULTS:Compared with normal control group,the TC,LDL-C,PCSK9 mRNA and protein,miRNA-27a levels of mice in model group were obvious-ly increased after 2 weeks of administration (P<0.05);LDLR protein level in liver tissue was obviously decreased (P<0.05). TC,LDL-C,PCSK9 mRNA and protein,miRNA-27a levels of hamsters in model group were obviously increased (P<0.05). Compared with model group,above-mentioned indexes of mice and hamsters in each administration group were obviously im-proved(P<0.05),which were positively correlated with dose. CONCLUSIONS:Resveratrol has preventive effect on model mice and improvement effect on model golden hamsters with hyperlipidemia. The mechanism may be down-regulating miRNA-27a ex-pression and PCSK9 protein expression in serum,to increase LDLR protein level in liver tissue,and finally reduce LDL-C level.
