To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

OBJECTIVETo investigate the effect of the intrauterine environment on pancreas ghrelin and L-type calcium channels of islet like cell clusters (ICCs) in neonatal rats.

METHODSDifferent birth weight neonatal rat models were established. The samples of entire pancreas or ICCs were collected at the first day after birth. Ghrelin, Cav1.2, Cav1.3 mRNAs and proteins were determined using real-time RT-PCR and immunohistochemistry respectively.

RESULTThe real-time RT-PCR revealed that ghrelin mRNA in SGA group were significantly higher than that of the AGA group (P <0.05). Cav1.2 mRNA of SGA group and LGA group was significantly lower than that of the AGA group; Cav1.3 mRNA of SGA group was significantly lower than that of the AGA group (P <0.05). The results of integral OD value of immunohistochemistry were consistent with those of real-time RT-PCR.

CONCLUSIONIntrauterine nutritional status may affect pancreatic endocrine cells differentiation and maturity, resulting in the difference of expression ghrelin and calcium channels in ICCs.

Objective To determine the expression of membrane-bound B lymphocyte stimulator (BLyS) protein and its mRNA in vitro of peripheral blood mononuclear cells (PBMCs) from individuals with systemic lupus erythematosus (SLE),and to investigate the role of interferon-?(IFN-?) on the expression of BLyS.Methods PBMCs were obtained from 25 SLE patients (mean age of 31+14) and 20 healthy volunteers (mean age of 28?10).They were randomized into IFN-?(5 ng/ml) group and control group.PBMCs were col- lected at 0,6,12 and 24 h for BLyS mRNA assessment using semi-quantitative reverse transcription-PCR (RT-PCR).PBMCs were also collected at 72 h for membrane-bound BLyS protein detection using flow cy- tometry (FACS) and direct immunofluorescence.Results①The expression of BLyS mRNA and membrane- bound protein in PBMCs was significantly higher in individuals with SLE compared with healthy controls (P＜0.05);②IFN-?enhanced BLyS mRNA expression in PBMCs in both healthy controls and SLE patients,with the greatest effect at 6 h (stimulated vs unstimulated,0.42?0.19 vs 0.25?0.14,P＜0.01;0.59?0.28 vs 0.44?0.21,P＜0.01 );③IFN-?also increased the expression of membrane-bound BLyS protein in both healthy con- trols and individuals with SLE (FACs,mean fluorescence intensity,4.5+3.0 vs 3.7~2.6,P

Objective To investigate the potential clinical factors associated with the prognosis and relapse of adult onset Still's disease(AOSD).Methods The factors possibly influencing the prognosis and relapse of AOSD were analyzed by logistic regression and COX regression in the cohort study.Ninety-six con- secutive inpatients of AOSD diagnosed based on Yamaguchi criteria in the hospital from March 1996 to September 2004 were included in the study.Results Nine cases(9.4%)were lost during the follow-up. Eleven patients(12.6%)were diagnosed as other diseases(5 with other rheumatic diseases,4 with tumor and 2 with infections)in the 87 follow-up cases.In 76 cases,3 patients(3.9%)died and 33 patients(43.4%) got remission over one year after treatment.Splenomegaly(OR=3.14,95%CI=1.01～9.74)and treated with methotrexate(OR=0.22,95%CI=0.07～0.67)were associated with the prognosis from the logistic regression analysis of the 76 cases.The serum ferritin(RR=I.05,95%CI=1.01～1.08)and treated with methotrexate (RR=0.13,95%CI=0.02～0.76)were associated with relapse from the COX regression analysis of the 61 remis- sion cases.Conclusion We need to be very cautious in the follow-up of AOSD patients because some of them may change to other diseases.Methotrexate may be an importent therapy of AOSD not only in improve- ment the prognosis but also in reduction of relapse.

ObjectiveTo systematically review the evidences of impact of exercise rehabilitation and adapted physical activity on psychomotor skills, motor abilities, and motor development in children with spastic cerebral palsy (CP). MethodsRelevant literature was retrieved from PubMed, Embase, Web of Science and CNKI, from January, 2010 to June, 2023. The contents were coded using International Classification of Diseases, Eleventh Revision, and International Classification of Functioning, Disability and Health; and evidences were analyzed with theoretical framework and code of ICD-11 and ICF. ResultsA total of nine articles were included, from Denmark, South Korea, Australia, Saudi Arabia, Ghana, India and Japan, published from 2015 to 2022. The intervention programs primarily involved exercise rehabilitation (including physical therapy) and adapted physical activity. Exercise rehabilitation included upper limb strength training, lower limb strength training, balance and coordination training, gait training, functional aerobic exercise, stretching and flexibility exercises, flexibility training, muscle relaxation techniques; ten to 50 minutes a time, two to six times a week,with the intensity of low to high, for six to 20 weeks. Adapted physical activities mainly involved adapted running training, virtual games; 60 minutes a time, two to four times a week, with the intensity of medium to high, for six to twelve weeks. Interventions primarily took place in medical and rehabilitation institutions, schools, and home-based communities, with professionals including occupational physical therapists, university researchers, community health personnel and teachers. The outcomes were mainly reflected in four aspects: psychomotor skills, motor abilities, motor development, and quality of life and well-being. In terms of psychomotor skills, adolescents with CP mastered running techniques and knowledge, and enhanced their response to balance threats. In terms of motor abilities, adolescents with CP showed an increase in muscle strength, enhanced muscle endurance, and an expansion of muscle tone; improvements in gait functionality, walking ability, and gait symmetry; increases in walking endurance; improvements in standing function; and improvements in dynamic balance; as well as enhanced control over balance posture. In terms of motor development, there was a significant improvement in activities of daily living, participation levels in school and leisure activities during free time, and an expanded range of motion. In terms of quality of life and well-being, adolescents with CP showed significant enhancements in self-confidence and self-esteem, significant relief from (spastic) pain, and improvements in social well-being and acceptance. ConclusionThis systematic review has synthesized the evidences of benefits of exercise rehabilitation and adapted physical activity on the psychomotor skills, motor abilities and motor development of children and adolescents with spastic CP. In terms of psychomotor skills, exercise rehabilitation and adapted physical activity help to improve the cognitive and motor skills of adolescents with spastic CP. In terms of motor abilities, exercise rehabilitation and adapted physical activity can improve muscle-related functions, gait and walking abilities, as well as balance and coordination. In terms of motor development, exercise rehabilitation and adapted physical activity significantly enhance activities of daily living and the level of participation in leisure physical activities. Finally, exercise rehabilitation and adapted physical activity can increase energy and motivation, alleviate pain, and enhance social well-being and acceptance.

OBJECTIVETo evaluate therapeutic effect of acupuncture at Sifeng (EX-UE 10) on infantile malnutrition.

METHODSMulticentral, randomized, controlled and single blind test was adopted. 222 infants of malnutrition were divided into an acupuncture group (n=110) and a medicine group (n=112). The acupuncture group were treated with acupuncture at bilateral Sifeng (EX-UE 10), once each week, for 4 times; and the medicine group were treated with oral administration of Yiqi Jianpi Oral Liquid, twice each day, one ample each time, for 4 weeks. The therapeutic effect was evaluated by improvement of symptoms and signs in the syndrome cumulative score scale, and changes of serum insulin-like growth factor-I (IGF-I), pre-albumin (PA), hemoglobin and red-cell count.

RESULTSTwo hundred and twenty-two cases were enrolled in the 4 centers and 212 cases completed the test. The acupuncture group in improvement of appetite, body weight, subcutaneous fat thickness of the abdomen, etc. were superior to the medicine group (P < 0.01), but there was no significant difference between the two groups in improvement of the body height. There was no significant increase of serum IGF-I level in the two groups, and the acupuncture group in increase of PA was superior to the medicine group (P < 0.05). After treatment, hemoglobin and red-cell count increased significantly in the treatment group (P < 0.01), and hemoglobin increased significantly in the medicine group.

CONCLUSIONAcupuncture at Sifeng (EX-UE 10) has obvious therapeutic effect on infantile malnutrition.

OBJECTIVETo evaluate the usefulness of serum alpha-fetoprotein (AFP) in clinical diagnosis and screening for hepatocellular carcinoma (HCC).

METHODSTotally 290 HCC patients, 48 liver cirrhosis patients, and 49 healthy subjects were enrolled in this study. Serum AFP analysis was performed to investigate the correlation between the serum AFP level in HCC and the clinical or biochemical parameters of the disease, which included the size and number of tumor and the TNM stage. Sensitivities and specificities of AFP in HCC prediction at different cut-off levels were determined.

RESULTSThe serum AFP level was significantly higher in HCC patients than in liver cirrhosis patients (P = 0.0274) and healthy subjects (P = 0.0001). Among 290 HCC patients, 95 patients (32.8%) were AFP-negative (AFP < 20 microg/L), 195 (67.2%) were AFP-positive (AFP > or =20 microg/L). Sensitivity and specificity of AFP at 20 microg/L cut-off was 67.2% and 29.2%, respectively, and the positive and negative predictive value was 85.2% and 12.8%, respectively. Sensitivity of AFP at 400 microg/L cut-off was only 42.8%. Serum AFP levels were significantly different among HCC with different tumor size (P = 0.0009), tumor number (P = 0.0001), and TNM stage [TNM I vs. TNM III-IV (P = 0.0001); TNM II vs. TNM III-IV (P = 0.0003)].

CONCLUSIONSIncreased serum AFP level is highly suggestive in HCC diagnosis. Combined with other imaging examinations, AFP level can be used for the screening of high risk population and for the follow-up of AFP-positive patients.

OBJECTIVETo study the clinicopathologic features, diagnostic criteria, differential diagnosis and treatment options of ovarian steroid cell tumor, not otherwise specified (NOS).

METHODSLight microscopy and immunohistochemical study was carried out in 8 cases of ovarian steroid cell tumor, NOS. The literature was reviewed.

RESULTSThe 7 cases of benign ovarian steroid cell tumor, NOS were composed mainly of polygonal cells with granular eosinophilic cytoplasm and larger cells with vacuolated cytoplasm. They resembled the architecture of normal adrenal gland, with formation of cell nests and trabeculae. The single case of malignant ovarian steroid cell tumor had evidence of significant cellular pleomorphism, haemorrhage and coagulative tumor necrosis. The mitotic count measured about 7 per 10 high-power fields. Immunohistochemical study showed that the tumor cells expressed calretinin and alpha-inhibin. Differential diagnosis included oxyphilic granulosa cell tumor, thecoma, Sertoli cell tumor and clear cell carcinoma. The treatment options of benign ovarian steroid cell tumor, NOS was local excision or ipsilateral salpingo-oophorectomy, while the malignant counterpart should be treated with a combination of surgery and chemotherapy, including administration of GnRH agonist.

CONCLUSIONSOvarian steroid cell tumor, NOS, is the most common type of ovarian steroid cell tumors. Most of which are associated with a benign clinical outcome. Immunohistochemistry is an important adjunct for diagnosis. The treatment options of ovarian steroid cell tumor, NOS depend on its malignant potential.

The present study investigated the influence of the methyl jasmonate and salicylic acid elicitors on the formation of phenylethanoid glycosides (PeG) in the suspension cultures of Cistanche deserticola. The results showed that methyl jasmonate and salicylic acid enhanced greatly the accumulation of PeG and echinacoside (Echin), but their optimum elicitation dosage and addition time were different. The yields of PeG and Echin were significantly increased in the presence of 5 micromol/L methyl jasmonate on day 14 (up to 2.59-fold and 3.82-fold, respectively), whereas treated with 50 micromol/L salicylic acid on day 28, the maximum content of them were, respectively, 2.71 and 3.16-fold higher than the untreated cell cultures.
