Plant growth retardant as one of plant growth regulator can inhibit the cell division, elongation and growth rate in shoot apical meristem (SAM), which can be reversed by gibberellin regulate the product of photosynthesis transfer to the root and rhizome part. As commonly used plant growth retardant, paclobutrazol, uniconazole, chlorocholine chloride, mepiquat chloride, choline chloride and daminozide are used to promote the growth of root and rhizome, call as "zhuanggenling", "pengdasu", "pengdaji" etc. Single or recombination of plant growth regulator is registered as pesticide, and called as pesticide "zhuanggenling" in this paper. Growth regulator which registered as a foliar fertilizer or fertilization was called agricultural fertilizer "zhuanggenling" in this paper. The author investigate the usage of "zhuanggenling" in the root and rhizome of medicinal plants cultivation from 2012 to 2014 in Sichuan province, Huangyuan town, Mianyang (Ophiopogonis Radix); Pengzhou Aoping town (Chuanxiong Rhizoma); Pengshan Xiejia town (Alismatis Rhizoma); Jiangyou Taiping town and Zhangming town (Aconiti Lateralis Radix Praeparata); Yunnan Wenshan (Notoginseng Radix et Rhizoma); Henan province, Wuzhidafeng Town (Rehmanniae Radix, Achyranthis Bidentatae Radix, Dioscoreae Rhizoma); Gansu Min county (Codonopsis Radix, Angelicae Sinensis Radix); Gansu Li county (Rhei Radix et Rhizoma). The result showed that "zhuanggenling" were applied in the most medicinal plant cultivation except Rhei Radix et Rhizoma. It has been applied widespreadly in Ophiopogonis Radix, Alismatis Rhizoma, Achyranthis Bidentatae Radix, Codonopsis Radix; Rehmanniae Radix, commonly in Angelicae Sinensis Radix application, and occasionally in Chuanxiong Rhizoma, Aconiti Lateralis Radix Praeparata, Notoginseng Radix et Rhizoma and Dioscoreae Rhizoma. In 53 collected sample from plantation areas, fifteen (28%) were pesticide "zhuanggenling", thirty-eight (72%) were pesticide "zhuanggenling". UPLC analysis results showed that 38 farmers fertilizer "zhuanggenling" content of 6 kinds of plant growth retardant. It is regarded that fertilizer "zhuanggenling" was dominant in medicinal plant cultivation, and that the plant growth retardant is added widespreadly in farm fertilizer "zhuanggenling". All evidence proves conclusively that "zhuanggenling" have been used in the proper way, whereas some others have been misused or even abused in the use regarding to type, number, use frequency. The root or rhizoma are increased to 20%-200%. But there is lack of evaluation to appraise the quality of medicinal materials from the aspects of research or industry. "zhuanggenling" has become a important Chemical control material besides fertilizer, insecticidal sterilization of pesticide

AIM:To investigate the inhibitory effect of apolipoprotein A-I mimetic peptide D-4F on the scaven-ger receptor A1 ( SR-A1 ) in macrophage-derived foam cells induced by oxidized low-density lipoprotein ( ox-LDL ) . METHODS:RAW264.7 cells were pretreated with different concentrations (12.5, 25 and 50 mg/L) of D-4F or 50 mg/L inactive control peptide scrambled D-4F (sD-4F) for 1 h or endoplasmic reticulum stress (ERS) inhibitor 4-phenylbutyr-ic acid (5 mmol/L) for 30 min, followed by the treatment with 100 mg/L ox-LDL for 12 h.In addition, the cells were pre-treated with 50 mg/L D-4F or sD-4F for 1 h, and then stimulated with 2 mg/L tunicamycin (TM;an ERS inducer), for 4 h.The viability of the cells was measured by MTT assay, and the content of intracellular total cholesterol ( TC) was meas-ured by a tissue/cell TC assay.The protein and mRNA levels of SR-A1 and glucose-regulated protein 78 (GRP78) were analyzed by Western blotting and quantitative real-time PCR, respectively.The fluorescence intensity of DiI-ox-LDL in the cells was detected by a multifunctional microplate reader.RESULTS:D-4F significantly reduced ox-LDL-induced macro-phage injury and intracellular cholesterol accumulation, and attenuated the ox-LDL-induced expression of SRA1 and GRP78 in a dose-dependent manner.Additionally, D-4F significantly inhibited the TM-induced protein expression of SR-A1 and GRP78, and attenuated the uptake of ox-LDL by macrophages.CONCLUSION: D-4F reduces ox-LDL-induced macro-phage cholesterol accumulation and injury by inhibiting SR-A1 expression.The mechanism may be related to the inhibition of ERS signaling pathway mediated by GRP78.

Objective To assess the heritability of serum uric acid in adult,using the classic twin design.Methods Adult Twins were recruited from the Qingdao Twin Registry.Uric acid,height,weight were measured.Zygosity in all the same-sex twin pairs was determined by 16 polymorphic markers.Heritability was assessed by structural equation models,with age,gender and body mass index(BMI) included as covariates.Results In total,687 twin pairs were available for data analyses,including 420 pairs of monozygotic and 267 pairs of dizygotic twins.After logarithm transformed,uric acid in males ( 17.47±1.91 ) was significantly higher than in females ( 15.22±1.70,P＜0.0001 ).After adjustment on age,sex and BMI,intraclass correlations for uric acid were 0.70 for monozygotic twins and 0.40 for dizygotic twins.The sex-limitation AE model,combining additive genetic and unique environmental factors,could produce the best fit for the data.Heritability estimate for uric acid was 70.5% (95% CI:65.9-74.6),with the proportion of unique environmental effects as 29.5%(95%CI:25.4-34.2).Conclusion Additive genetic effects appeared to be the major contributor to the variation of uric acid in this twins sample being studied.

OBJECTIVE: To study the efficacy and safety of vitamin D as an adjuvant therapy for childhood pneumonia through a systematic review. METHODS: Cochrane Library, PubMed, EMbase, CNKI, Wanfang Data, and Weipu Data were searched for randomized controlled trials (RCTs) of vitamin D as the adjuvant therapy for childhood pneumonia published up to August 2019. Literature screening, quality assessment, and data extraction were performed based on inclusion and exclusion criteria. Revman 5.3 was used to perform the Meta analysis of outcome indicators. RESULTS: A total of 7 RCTs with 1 527 children were included, with 762 children in the vitamin D adjuvant therapy group and 765 children in the control group. The results of the Meta analysis showed that vitamin D adjuvant therapy had no effect on recovery time (P=0.67), length of hospital stay (P=0.73), and time to relief of fever (P=0.43). Furthermore, it did not reduce the recurrence rate (P=0.14), rate of adverse events (P=0.20), and mortality rate (P=0.98) of childhood pneumonia. CONCLUSIONS Current evidence shows that vitamin D adjuvant therapy has no marked efficacy in the treatment of childhood pneumonia.

OBJECTIVETo describe the status of nutrition and health related indices in the Chinese population.

METHODSA stratified multi-stage cluster sampling was used from 31 provinces, autonomous regions, and municipalities. The survey was done in 2002, including data gathered from questionnaires, interviews, physical examinations, measurement of biochemical indices, and dietary investigation.

RESULTSCereals accounted for 48.5% of all the sources of energy in urban and 61.4% in rural populations. Daily mean percentages of calories for total fat were 35.0% in urban and 27.5% in rural areas. The prevalence rates of stunting and underweight were 14.3% and 7.8% respectively in young children under 5-year-old. The prevalence of vitamin A deficiency was 9.3% in Chinese children aged 3-12 years old. The total prevalence of anemia was 15.2% in general population of all ages. The prevalence of anemia in young adults was significantly higher in women than in men. The total prevalence rates of overweight and obesity were 17.6% and 5.6%, respectively. The prevalence rates of hypertension, diabetes, hypercholesteremia, hypertriglyceridemia, or low serum high density lipoprotein cholesterol were 18.8%, 2.6%, 2.9%, 11.9%, 7.4% respectively in Chinese adults aged 18 and over. The rates of awareness, treatment, and under control among hypertensives were 30.2%, 24.7%, and 25.0%, respectively. Significant regional and age differences were revealed in the dietary habit and the prevalence of various diseases. The prevalence of diseases associated with malnutrition were higher in rural than in urban areas. In contrast, the prevalence of conditions associated with overconsumption and inappropriate dietary patterns were higher in urban than in rural populations.

CONCLUSIONChinese people were currently suffering from both problems on nutrition related issues and burdens of diseases which were characterized in nutrient deficiencies and overconsumption, malnutrition and noncommunicable conditions associated with overconsumption and inappropriate diet. The difference of nutrition and health status between rural and urban people was also seen.

Objective: To evaluate the efficiency and safety of low intensity conditional regimen for children with Fanconi anemia (FA) receiving allogenic hematopoietic stem cells transplantation (allo-HSCT). Methods: Four patients diagnosed as Fanconi anemia were enrolled in this study. One patient received HLA-identical sibling donor hematopoietic stem cell transplantation, two patients underwent unrelated donor matched (UD) HSCT, and one patient received unrelated cord blood transplantation. The conditional regimen consisted of Busulfan with low dose of cyclophosphamide. Results: All 4 cases succeeded in allo-HSCT. The median time for neutrophils engraftment was 11(9-15) day, median time to platelets (PLT) engraftment was 12 (8-28) day. One case occurred with grade I of aGVHD, 1 case with hemorrhagic cystitis. No patient happened with hepatic veno-occlusive disease (VOD). Conclusion: Low intensity of conditional regimen is efficient and safe which should be recommended for FA patients with HSCT.

Objective: To evaluate the prognostic significance of early phase full donor chimerism (FDC) after myeloablative allogeneic peripheral blood stem cell transplantation (allo-PBSCT). Methods: The clinical data of 72 hematological patients received myeloablative allo-PBSCT from Feb. 2016 to Jul. 2017 were analyzed retrospectively. The median age was 36.5 years (range 4-59), 44 were males and 28 females. Of the donors, there were 35 HLA matched sibling donors, 27 haploidentical donors and 10 unrelated donors. Polymerase chain reaction amplification of short tandem repeat sequence (PCR-STR) was used to detect donor cell chimerism (DC) rate of recipient bone marrow at one, two and three months after transplantation. Results: The median follow-up was 462 d (range: 47-805 d), 55 cases were still alive, and 45 cases were disease-free survival (DFS) at the end of follow-up. The 2-year overall survival (OS) and DFS were (68.9±7.7)% and (59.5±6.3)%, respectively. A number of 16 cases underwent relapses, with 2-year cumulative incidence of (24.1±5.3)%. The median time of recurrence was 157(32-374) d. Forty cases (55.6%) developed acute graft-versus-host diseases (aGVHD), with median time of 35.5 (13-90) d. Chronic GVHD (cGVHD) occurred in 23 patients (31.9%), with median time of 169 (94-475) d. Univariate analysis found the following factors were not related to OS, DFS or relapse rate (RR), including age, sex, blood type and sex of donor-recipient, occurrence of aGVHD and cGVHD. The OS and DFS in cases reached FDC and no FDC at two months after transplantation were (85.2±6.9)% vs (66.1±7.7)% (P=0.051) and (76.7±7.7)% vs (48.9±8.1)% (P=0.021), respectively. The RR rate in FDC group was lower than that in no FDC group [(16.6±6.8)% vs (30.4±7.8)%, P=0.187, respectively]. Conclusion: The present study confirmed the important value for predicting the prognosis with whether or not the patients reached FDC at the early phase after allo-PBSCT. The OS and DFS in cases with FDC at two months after transplantation were significantly higher than those of no FDC patients.

The present study was to investigate whether endoplasmic reticulum stress (ERS) was involved in oxidized low density lipoprotein (ox-LDL)-induced scavenger receptor A1 (SR-A1) upregulation in macrophages. RAW264.7 cells were pretreated with 20 mmol/L of 4-phenylbutyric acid (PBA) for 30 min and then treated with ox-LDL (50 mg/L) for 12 h or stimulated with 2 mg/L tunicamycin (TM) or 2 μmol/L thapsigagin (TG) for 4 h. In addition, RAW264.7 cells were incubated with 0.5, 1 and 2 mg/L TM for 4 h or treated with 2 mg/L TM for 1, 2 and 4 h, respectively. The intracellular total cholesterol (TC) content was measured using a tissue/cell total cholesterol assay kit. The protein and mRNA expressions of SR-A1 and glucose-regulated protein 78 (GRP78) were analyzed by Western blot and real-time PCR, respectively. Dil-ox-LDL uptake was detected using a microplate reader. The results showed that ox-LDL-induced cholesterol accumulation in macrophages was attenuated by PBA, an ERS inhibitor. Ox-LDL caused significant SR-A1 upregulation with concomitant activation of ERS as assessed by upregulation of GRP78, whereas PBA significantly inhibited the ox-LDL-induced SR-A1 upregulation (P < 0.05) and slightly decreased GRP78 expression by 39.3% (P = 0.057). TM, an ERS inducer, upregulated SR-A1 protein expression and ox-LDL uptake in dose- and time-dependent manner, but had no significant effect on SR-A1 mRNA level. However, the TM- or TG-induced SR-A1 upregulation and ox-LDL uptake were significantly mitigated by PBA. These data indicate that ERS plays a critical role in ox-LDL-induced SR-A1 upregulation, which in turn enhances the foam cell formation by uptaking more ox-LDL.

Objective: To compare eficacy and safety of porcine antihuman lymphocyte immunoglobulin (pALG) and rabbit antithymocyte immunoglobulin (rATG) as a part of alternative donor allogeneic hematopoietic stem cell transplantation (AD allo-HSCT) for severe aplastic anemia (SAA). Methods: The clinical data of 46 SAA patients received AD allo-HSCT from January 2006 to November 2016 were retrospectively analyzed. The cohort of patients were divided into two groups based on rATG or pALG as a part of conditioning regimen to compare implantation rate, transplantation related complications and outcome. Results: In rATG group 30 patients achieved ANC reconstitution, 27 patients achieved PLT reconstitution. In pALG group all 16 patients achieved ANC and PLT reconstitutions. There were no significant differences between the two groups in terms of acute graft-versus-host disease (aGVHD) (P=0.475), Ⅲ-Ⅳ grade aGVHD (P=0.876), chronic GVHD (cGVHD) (P=0.309), extensive cGVHD (P=0.687), graft rejection (GR) (P=0.928), bloodstream infection (P=0.443), invasive fungal disease (P=0.829), cytomegalovirus viremia (P=0.095) respectively. Prospective 5-year overall survival (OS) in rATG and pALG groups were (75.1±8.2)% and (53.6±13.3)% with median follow-up of 14(2-102) and 23(4-63) months, respectively (P=0.190). Conclusion: As a part of conditioning regimen, pALG could achieve similar efficacy as rATG, without increasing the incidences of transplantation complications such as GVHD, GR and infection, in the setting of AD allo-HSCT for SAA patients.
