OBJECTIVETo establish a method to test citrinin (CIT) in monascus products by immuno-affinity chromatography (IAC)-high performance liquid chromatography (HPLC), and to detect the content of CIT in monascus products in Fujian province.
METHODSIAC-HPLC was applied to detect the CIT content in monascus products. The conditions to use HPLC were as follows: C(18) reversed-phase chromatographic column, 150.0 mm×4.6mm×3 µm; mobile phase: the volume ratio of acetonitrile and 0.1% phosphoric acid solution at 65:35; isocratic elution; column temperature: 28°C; flow velocity: 0.8 ml/min; fluorescence detector, excitation wavelength (λ(ex)) was 331 nm and emission wavelength (λ(em)) was 500 nm. The standard curved was established by the linear regression of peak area (Y) to CIT content (X, ng/ml). The accuracy and precision of the method would then be verified. And 32 kinds of monascus products were determined and their color values were compared by this method.
RESULTThe standard curve established in this study was Y = 4634.8X-136.42, r = 1.000; whose limits of detection was 20 µg/kg and the limits of qualification was 64 µg/kg. In the range between 200 and 800 µg/kg, the standard recovery rate was 98.9% - 110.0% (n = 3), and the relative standard deviation (RSD) was 0.51% - 1.76%. Out of the 32 samples, CIT was detected from 11 samples of monascus rice, 9 samples of monascus powder and 5 samples of monascus pigments, the content was around 0.212 - 14.500 mg/kg. 4 out of 7 functional monascus samples were detected out CIT, whose content at 0.142 - 0.275 mg/kg.
CONCLUSIONThe method to detect CIT in monascus products by IAC-HPLC has been established.

OBJECTIVETo investigate the factors that influence survival of the patients with differentiated thyroid carcinoma in young people and evaluate the efficiency of unilateral lobectomy plus isthmectomy with therapeutic cervical lymph node dissection and postoperative TSH (thyroid stimulating hormone) suppressive therapy.
METHODSOne hundred and thirty-one patients under 30 years old with differentiated thyroid carcinoma treated in this hospital (14 cases no more than and 117 cases more than 16 years) from Jan. 1st, 1985 to Dec. 31st, 1997 were retrospectively reviewed. One hundred and twenty-eight patients were received only surgery and TSH suppressive therapy, and 3 patients received chemotherapy or radiotherapy because of the progressive metastasis in necks or mediastina. A multivariate analysis was performed in these patients by the Cox proportional hazard model.
RESULTSThe mean follow-time (x +/- s) of all patients were (140.86 +/- 43.76) months, with range from 20 to 229 months; Ninety-eight patients followed more than 10 years. Ten patients died of thyroid cancer. The overall 10-year survival rate was 97.18%. The 10-year survival rate for patients < or = 16 years of age and > 16 years were 75.97% and 96.57% respectively (P = 0. 0006). The 10-year survival rate for women and men were 94.91% and 93.69% respectively (P = 0.5261). The 10-year survival rates of patients with papillary thyroid carcinoma and follicular thyroid carcinoma were 93.77% and 96. 55% respectively (P = 0.8137). For patients with tumor size of < or = 1 cm, 1-4 cm and >4 cm the survival rate was 100.0%, 96.40%, and 80.67% respectively (P = 0. 0589). The 10-year survival rates of patients with or without lymph node metastasis were 88.37% and 100. 0% respectively (P = 0.0313). For patients of with or without distant metastasis, The survival rate was 96.64% or 60.00% (P = 0.0000). The 10-year survival rates with or without recurrence were 86. 67% and 95.48% respectively (P = 0. 5681). Using multivariate analysis, risk factors that independently influence survival were distant metastasis, tumor size and age.
CONCLUSIONSThe distant metastasis, tumor size and age at diagnosis were the independent factors influencing survival significantly. The status of lymph node metastasis may have certain effect on the prognosis. Unilateral lobectomy plus isthmectomy with a therapeutic cervical lymph node dissection followed by postoperative TSH suppressive therapy is a favourable model to children and young adults with DTC without distant metastasis, but to the patients with distant metastasis, their prognosis of this therapy model is disappointing.

OBJECTIVETo investigate the mRNA and protein expression of nucleostemin (NS) in human esophageal squamous cell carcinoma.
METHODSThe mRNA and protein expression of NS were detected in 31 mucosal atypical hyperplasia specimens, 62 esophageal squamous cell carcinoma specimens and the matched normal esophageal mucosa samples by RT-PCR and immunohistochemistry method, respectively.
RESULTSThe positive expression rate of NS protein in normal esophageal mucosa, atypical hyperplasia and esophageal squamous cell carcinoma was 17.7% (11/62), 41.9% (13/31) and 69.4% (43/62), respectively. There was a significant difference among the above three groups (chi2 = 33.676, P < 0.01). The expression levels of NS mRNA in esophageal squamous cell carcinoma (0.971 +/- 0.121) was significantly higher than that in the atypical hyperplasia (0.913 +/- 0.085) and also in the normal esophageal mucosa (0.866 +/- 0.103; F = 14.829, P < 0.01). The expression level of both NS protein and mRNA was positively correlated with histological grade, infiltration depth, and lymph node metastasis (P < 0.05), but not with age, gender or pathological type (P > 0.05).
CONCLUSIONOur results indicate that nucleostemin mRNA and protein are over-expressed in human esophageal squamous cell carcinoma, and it may be related with its oncogenesis.

Objective To explore the value of degree of cranial suture closure in forensic adult age estimation by thin-layer CT scan and establish an adult age estimation model of the Han nationality. Methods Thin-layer CT scan samples of the heads of 220 healthy Sichuan Han adults (110 males, 110 females) aged 20 to 70 were collected, of which 20 samples (10 males, 10 females) were randomly selected as test samples. The sagittal suture, coronal suture (both left and right) and lambdoid suture (both left and right) were respectively and equally divided into 2 segments, and every segment was equally divided into 10 layers and the corresponding multiplanar reformation (MPR) images were selected. The closure of cranial sutures on MPR images was classified into the grades 1-7. The correlations between cranial sutures and age were analyzed to build regression equation for age estimation. Results The degree of closure of sagittal suture, coronal suture (both left and right) and lambdoid suture (both left and right) was positively correlated with age. The coefficient of determination (R2) of regression equation was 0.419 in males, 0.589 in females, and 0.522 in all samples. The results of the verification test showed that the mean absolute error (MAE) was 6.39 years in males, 6.16 years in females, and 6.29 years in all samples. Conclusion There was a higher accuracy in adult age estimation by thin-layer CT scan of cranial sutures. The age of Han nationality adults can be estimated by the degree of cranial sutures closure.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.
METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).
RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).
CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.

Objective: To evaluate the safety of simultaneous administration of quadrivalent influenza split virion vaccine and 23-valent pneumococcal polysaccharide vaccine in adults aged 60 years and older. Methods: From November 2021 to May 2022, eligible participants aged 60 years and older were recruited in Taizhou City, Jiangsu Province, China, and a total of 2 461 participants were ultimately enrolled in this study. Each participant simultaneously received one dose of quadrivalent influenza split virion vaccine and one dose of 23-valent pneumococcal polysaccharide vaccine. The safety was observed within 28 days after vaccination. Safety information was collected through voluntary reporting and regular follow-ups. Results: All 2 461 participants completed the simultaneous administration of both vaccines and the safety follow-ups for 28 days after vaccination. The mean age of the participants was (70.66±6.18) years, with 54.61% (1 344) being male, and all participants were Han Chinese residents. About 22.51% (554) of the participants had underlying medical conditions. The overall incidence of adverse reactions within 0-28 days after simultaneous vaccination was 2.07% (51/2 461), mainly consisting of Grade 1 adverse reactions [1.83% (45/2 461)], with no reports of Grade 4 or higher adverse reactions or vaccine-related serious adverse events. The incidence of local adverse reactions was 0.98% (24/2 461), primarily presenting as pain at the injection site [0.93% (23/2 461)]. The incidence of systemic adverse reactions was 1.42% (35/2 461), with fever [0.85% (21/2 461)] being the main symptom. In the group with underlying medical conditions and the healthy group, their overall incidence of adverse reactions was 2.53% (14/554) and 1.94% (37/1 907), respectively. The incidence of local adverse reactions in the two groups was 1.62% (9/554) and 0.79% (15/1 907), respectively, and the incidence of systemic adverse reactions was 1.44% (8/554) and 1.42% (27/1 907), respectively, with no statistically significant differences between them (all P>0.05). Conclusion: It is safe for adults aged 60 years and older to receive quadrivalent influenza split virion vaccine and 23-valent pneumococcal polysaccharide vaccine at the same time.
