Objective: To establish the methods for extraction and isolation of punicalagin from pomegranate peel, and further study the purification and quantification of punicalagin. Methods: Using an ultrasonic-assisted extraction method, punicalagin in pomegranate peel was extracted at room temperature by 50% ethanol with 20-fold volume of raw material. The content of punicalagin in the crude extract was determined by HPLC. To optimize the purification process of punicalagin, static adsorption and desorption experi-ments were employed to study five kinds of macroporous adsorbent resins (D101, A8-8, NKA-9, HPD-100 and HPD-500) for the one with the highest purification efficacy of punicalagin. In addition, the technical parameters of the macroporous adsorbent resin were opti-mized to obtain punicalagin with higher purity. Punicalagin was further separated and purified by using a reverse phase MCI GEL CHP20P column. Results:HPD500 resin showed the best ability to absorb and separate punicalagin in among five kinds of macro-porous adsorbent resins. The best technical parameters were as follows:the mass concentration of sample solution was 15 mg·ml-1 , the loading amount was 2BV, the pH was 2 and the eluting solvent was 8BV of 30% ethanol. With the best process as described a-bove, the content of punicalagin extracted from pomegranate peel increased from 10. 3% to 30. 7%. The obtained punicalagin could be further purified to 61. 3% from 30% in ethanol eluate by the reverse phase MCI GEL CHP20P column. Conclusion:HPD500 resin is the most effective in the purification of punicalagin from pomegranate peel, and the content of punicalagin can be dramatically increased after the purification by a reverse phase MCI GEL CHP20P column. The optimized process shows good reproducibility and stability.

Objective To investigate the association of the polymorphism of the N-acetyltransferase 2 (NAT2 )gene with isoniazid-induced hepatotoxicity and anti-tuberculous treatment efficacy in Chinese Han patients with tuberculosis(TB).Methods A total of 108 TB patients who received initial anti-TB treatment were followed up prospectively.A polymerase chain reaction direct sequencing approach was used to detect genetic polymorphisms of the NAT2 gene.Associations between NAT2 genotype and isoniazid-induced hepatitis/early treatment were analyzed.Chi-square test was used for statistical analysis. Results Among the 108 TB patients, intermediate-acetylators (IA ) was the most frequent NAT2 genotype with the proportion of 54.63%(59/108).The proportion of rapid-acetylators(RA)was 33.33%(36/108),slow-acetylators (SA)was 10.19%(11/108)and super-rapid acetylators was 1 .85 % (2/108). Among the 20 patients who developed drug-induced hepatitis,2 were RA,5 were SA and 13 were IA. Regarding NAT2 genotype,RA patients had a lower incidence of hepatotoxicity (OR =0.176,95 %CI :0.038-0.809,P =0.014)and SA patients were more likely to developed drug-induced hepatic injury (OR=4.556,95 %CI :1 .231 -16.854,P =0.044 ).Statistical analysis revealed that the frequency of variant diplotypes,NAT2*4/*6A (OR=7.741 ,95 %CI :2.653-22.586,P <0.01 )and NAT2 *6A/*6A (OR=15 .353,95 %CI :1 .506 -156.552,P =0.020)were significantly increased in TB patients with hepatotoxicity.NAT2 *4/*4 was less likely to developed hepatic injury (OR =0.176,95 %CI :0.038-0.809,P =0.014).Among the 58 culture-positive patients,12(31 .03%)were persistent culture positive after 2 months standard therapy.Early treatment failure was observed with significantly higher incidence rate in RA than other genotypes (OR = 7.200, 95 % CI :1 .794-28.900, P = 0.008). Conclusions In Chinese Han TB patients,IA is the most frequent NAT2 genotype.The SA status of NAT2 is a risk factor of isoniazid-induced hepatotoxicity.The diplotype of NAT2 *6A has clearly high risk of isoniazid-induced hepatotoxicity.In contrast,NAT2 * 4/* 4 is protective diplotype.RA is associated with early treatment failure in culture-positive patients.

Objective:
To investigate the genotypes and prognosis of infants with definitive diagnosis of inherited metabolic diseases during neonatal screening in Zhejiang Province from 2009 to 2021, so as to provide insights into the management of birth defects.
Methods:
The medical records of infants with definitive diagnosis of inherited metabolic diseases by tandem mass spectrometry during neonatal screening in Zhejiang Province from 2009 to 2021 were collected from the database created by Zhejiang Provincial Center for Neonatal Disease Screening. The prevalence, genotypes and prognosis of inherited metabolic diseases were analyzed.
Results:
A total of 1 038 infants were definitively diagnosed with inherited metabolic diseases in Zhejiang Province from 2009 to 2021, with an overall incidence rate of 1/4 535. There were 400 infants with amino acid metabolic disorders (AAD), 342 infants with fatty acid oxidation metabolic disorders and 296 infants with organic acid metabolic disorders (OAD), with incidence of 1/11 767, 1/13 763 and 1\15 902, respectively. There were 32 types of diseases, including 13 types of AAD, 8 types of FAOD and 11 types of OAD identified, and phenylketonuria and tetrahydrobiopterin deficiency (PKU/BH4D), primary carnitine deficiency (PCD) and methylmalonic academia (MMA) were detected as the most common forms of AAD, FAOD and OAD, with incidence of 1/20 827, 1/24 262 and 1\49 030, respectively. A total of 789 infants received genetic testing (76.01%), and genetic testing was performed among 70.00% of infants with AAD, 83.04% of infants with FAOD and 76.01% of infants with OAD. The c.728G >A (p.R243Q) variant was the most common mutation in infants with PKU (29.17%), c.1400C>G (p.S467C) variant was the most common mutation in infants with PCD (33.46%), c.609G>A (p.W203X) variant was the most common mutation in infants with combined MMA (40.00%), and c.1663G>A (p.A555T) variant was the most common mutation in infants with MMA (17.86%). Among the 997 infants (96.05%) with successful follow-up, 973 infants (93.74%) had normal intelligence and physical developments, and 41 infants died (3.95%), including 9 deaths due to AAD, 15 deaths due to FAOD and 17 deaths due to OAD.
Conclusions
The incidence of PKU, PCD and MMA was high among infants with inherited metabolic diseases in Zhejiang Province from 2009 to 2021, with c.728G>A (p.R243Q), c.1400C>G (p.S467C) and c.609G>A (p.W203X) variants as common gene mutations, respectively. Most infants with inherited metabolic diseases had a favorable prognosis; however, the mortality of OAD was relatively high.

The aim of this study is to develop monoclonal antibody against human hepatocyte growth factor activator inhibitor 1 (HAI-1) for future study of HAI-1. The cDNA fragments of human hepatocyte growth factor activator inhibitor 1 (HAI-1) were subcloned to construct GST-HAI-1 fusion protein expression vectors. The vectors were transformed into E. coli and fusion protein expression was induced by IPTG. The GST-HAI-1 fusion proteins were separated on preparative SDS-PAGE and recovered by electroelution, and used to immunize BALB/c mice. Hybridomas producing monoclonal antibodies against human HAI-1 were prepared by cell fusion technique and characterized by ELISA, Western Blot and immunohistochemical staining. One hybridoma cell line, ZMC6, was obtained, which produces specific antibody against the expressed GST-HAI-1 fusion protein. The monoclonal antibody recognizes both the membrane-type and secretory-type HAI-1 proteins of colorectal tissue. The successful development of anti-HAI-1 antibody provides a powerful tool for further investigation on HAI-1's function.
