Tripterygium wilfordii has exihibited multiple pharmacological activities, such as anti-inflammatory, immune modulation, anti-tumor and anti-fertility. T. wilfordii have been used for the therapy of inflammation and autoimmune diseases including rheumatoid arthritis, immune complex nephritis and systemic lupus erythematosus clinically. However, it is well known that T. wilfordii has small margin between the therapeutic and toxic doses and could cause serious injury on digestive, reproductive and urogenital systems. Among all the organs, liver is one of the most remarkable targets of T. wilfordii-induced toxicities, and the damage is more serious than others. It is generally accepted that T. wilfordii-induced liver injury is a result of the combined effects of toxic elements of T. wilfordii. It is reported in several studies that the mechanism of T. wilfordii-induced liver injury may be related to lipid peroxidation, cell apoptosis and immune damage, and so on. Licorice is one of the most commonly used Chinese herbal medicine, with effects of heat- clearing and detoxicating, anti-inflammatory and hepatoprotective, reconciling various drugs, and so on. Licorice often accompany T. wilfordii in clinical application which can significantly reduce the liver injury induced by T. wilfordii. The attenuated effect is exact, but the mechanism is still a lack of in-depth study. This paper reviews the studies on T. wilfordii-induced liver injury and the related mechanism as well as licorice and other traditional Chinese medicine accompany T. wilfordii to reduce the injury in recent years, so as to provide reference for related research in the future.

Objective:To investigate the effects of medroxyprogesterone acetate combined with a levonorgestrel-releasing intrauterine contraceptive system (Mirena) on the levels of sex hormone and vascular endothelial growth factor in patients with moderate and severe endometriosis after laparoscopic surgery.Methods:A total of 102 patients with endometriosis who received laparoscopic conservative surgery in Hangzhou Ninth People's Hospital from October 2015 to May 2018 were retrospectively analyzed. They were randomly assigned to undergo either medroxyprogesterone acetate treatment alone (control group, n = 51) or medroxyprogesterone acetate treatment + levonorgestrel-releasing intrauterine contraceptive system application (observation group, n = 51) for 6 successive months. Clinical efficacy, serum luteinizing hormone, follicle-stimulating hormone, estradiol and vascular endothelial growth factor levels, Visual Analogue Scale score, endometriosis recurrence rate, and adverse reactions were compared between the control and observation groups. Results:Total effective rate in the observation group was significantly higher than that in the control group [94.12% (48/51) vs. 80.93% (41/51), χ2 = 4.320, P < 0.05]. At 6 months after surgery, serum luteinizing hormone, follicle-stimulating hormone, estradiol and vascular endothelial growth factor levels in the observation group were (5.72 ± 0.53) U/L, (5.05 ± 0.91) U/L, (156.02 ± 21.80) pmol/L and (155.39 ± 24.72) ng/L respectively, which were significantly lower than those in the control group [(6.51 ± 0.67) U/L, (5.73 ± 0.68) U/L, (177.20 ± 23.20) pmol/L and (186.22 ± 28.14) ng/L, t = 6.604, 4.275, 4.747 and 5.878, all P < 0.05). At 3 and 6 months after surgery, Visual Analogue Scale score in the observation group were (2.39 ± 0.33) points and (1.27 ± 0.20) points respectively, which were significantly lower than those in the control group [(2.72 ± 0.40) points, (1.52 ± 0.25) points, t = 4.545 and 5.577, both P < 0.05]. Two-year follow-up results revealed that endometriosis recurrence in the observation group was significantly lower than that in the control group [1.96% (1/51) vs. 13.73% (7/51), χ2 = 4.883, P < 0.05]. There was no significant difference in total incidence of adverse reactions between the two groups [15.69% (8/51) vs. 13.73% (7/51), χ2 = 0.078, P > 0.05]. Conclusion:Application of medroxyprogesterone acetate combined with a levonorgestrel-releasing intrauterine contraceptive system after laparoscopic surgery for moderate and severe endometriosis can effectively regulate serum levels of sex hormone and vascular endothelial growth factor, decrease endometriosis recurrence rate and is highly safe. This method is worthy of clinical promotion.

Abstract: Objective To collect and organize malaria case data in Hubei Province from 2017 to 2021, compare and analyze the malaria epidemic characteristics on the before and after malaria elimination, and provide scientific support for Hubei Province to further optimize the comprehensive strategies to prevent re-transmission after the elimination of malaria. Methods The study was conducted by collecting the data of reported malaria cases of Hubei during 2017-2021 from the Infectious Disease Surveillance Reporting and Management System, and conducting the epidemiological characteristics of malaria on pre-elimination (2017-2019) and post-elimination (2020-2021). Results A total of 429 cases of imported malaria were reported in Hubei Province from 2017 to 2021, and the malaria epidemic showed an obvious trend of rising first and then falling. On the pre-malaria elimination, 374 malaria cases were reported, including 262 cases of P.falciparum (70.05%); on the post-malaria elimination, 55 malaria cases were reported, including 25 cases of P.falciparum (45.45%). There was a statistically significant difference in the proportion of infections caused by the four types of malaria parasites before and after the elimination of malaria (χ2=14.248, P<0.05). On the pre-malaria elimination, the peak of disease onset mainly occurred in January, July, and November; on the post-malaria elimination, the peak of disease onset mainly occurred in January to February, and December. Both before and after malaria elimination, the reported cases were mainly concentrated in Wuhan, Yichang, Huangshi, Xiangyang, Shiyan and Huanggang, but the range of cases showed a clear trend of narrowing. Before and after malaria elimination, malaria cases in Hubei Province were mainly among young and middle-aged males aged 30-49. The proportions of workers and migrant workers increased from 37.70% and 9.09% before the elimination to 50.91% and 18.18% after the elimination, respectively, with a statistically significant difference (χ2=17.839, P<0.05). The percentage of interval from onset of illness to initial diagnosis ≥ 5d decreased from 21.66% before the elimination to 10.91% after the elimination (χ2=6.448, P<0.05). The percentage of definitive diagnosis of malaria at initial diagnosis in town clinic increased from 18.18% before the elimination to 50.00% after the elimination. The proportion of malaria cases diagnosed by county-level medical institutions increased from 22.73% before the elimination to 34.55% after elimination. There was no statistically significant difference in the proportion of malaria cases diagnosed by medical institutions at all levels before and after the elimination of malaria (χ2=5.630, P>0.05). The proportion of cases with the interval between initial diagnosis and diagnosis within 24h increased from 43.85% before the elimination to 70.91% after the elimination. There was a statistically significant difference in the proportion of cases with the interval between initial diagnosis and diagnosis before and after the elimination of malaria (χ2=14.006, P<0.05). Before and after malaria elimination, all reported cases were mainly imported from African countries. Conclusions There are imported malaria cases reported every year in Hubei Province before and after the elimination of malaria, which poses a great challenge to the prevention of re-transmission. Therefore, it is necessary to strengthen the surveillance system, detect and standardize the treatment of imported malaria cases in a timely manner, conduct targeted retransmission risk surveys and assessments, and consolidate the achievements of malaria elimination.

OBJECTIVETo investigate the effect and possible mechanism of complete Freund's adjuvant induced chronic pain on later function of learning and memory in neonatal rats.
METHODSSixty Sprague-Dewley rat pups (10 litters of 6 pups) were randomly divided into control group and chronic pain group (n = 30 in each group). In the chronic pain group, left hind paws of the rats were treated with subcutaneous injection of 20 microl of CFA on postnatal day-2. The control rat pups received normal saline. The hippocampus of rats were separated on postnatal days 10 and 21 (one rat in each group from every litter, n = 10). The expression of Bcl-2 and BDNF mRNA were investigated by RT-PCR. Morris water maze tests were performed on day 21 (one rat in each group from every litter, n = 10).
RESULTSIn hidden-platform training of Morris water maze, the mean escape latency of rats in the chronic pain group were longer than that of the control rats. In spatial probe tests, the average percentages of the swimming time and distances in the platform quadrant in the pain group rats were less than those in the control group. There was no significant difference in visible-platform training between the two groups. The Bcl-2 and BDNF mRNA expressions in hippocampus of the pain group rats were lower than those in the control at day 10, but no significant difference at day 21.
CONCLUSIONChronic pain stress induced by CFA impairs the spatial learning and memory function in neonatal rats. These effects might exert through down-regulating Bcl-2 and BDNF mRNA expression in the hippocampus.

BACKGROUNDMutations in fumarylacetoacetate hydrolase (FAH) gene can lead to tyrosinemia type 1 (HT1), a relatively rare autosomal recessive disorder. To date, no molecular genetic defects of HT1 in China have been described. We investigated a Chinese family with a HT1 child to identify mutations in FAH.
METHODSDNA sequencing was used for mutations screening in FAH gene. Real-time polymerase chain reaction (PCR) was performed to determine the FAH gene expression level. To confirm the presence of degradation by the nonsense-mediated mRNA decay pathway (NMD), the fragments containing R237X mutations were analyzed by primer introduced restriction analysis-polymerase chain reaction (PIRA-PCR) and cDNA sequencing. Finally, the effects of the mutations reported in this study were predicted by online softwares.
RESULTSA boy aged 3 years and 8 months was diagnosed clinically with HT1 based on his manifestations and biochemical abnormalities. Screening of FAH gene revealed two heterozygous mutations R237X and L375P transmitted from his mother and father respectively. In this pedigree, the amount of FAH mRNA relative to a healthy control was 0.44 for the patient, 0.77 for his mother and 1.07 for his father. Moreover, both PIRA-PCR and cDNA sequencing showed significant reduction of the FAH mRNA with R237X nonsense mutation. The missense mutation of L375P was not reported previously and prediction software showed that this mutation decreased the stability of protein structure and affected protein function.
CONCLUSIONSThis is the first case of HT1 analyzed by molecular genetics in China. The R237X mutation in FAH down- regulates the FAH gene expression, and the L375P mutation perhaps interrupts the secondary structure of FAH protein.

OBJECTIVETo explore the effect of auricular points sticking-pressing (APSP) in treating post-cesarean hypogalactia (PCH).
METHODSA randomized, controlled, single-blinded clinical trial on 116 patients with PCH was carried out. They were equally assigned to the treatment group and the control group. The treatment group received APSP, with the pellets pressed for 4 times daily, while the control group was only asked to do lactation to meet infant demand. The therapeutic efficacy and the changes in scores of traditional Chinese medicine (TCM) syndrome, volume of milk secretion, supplementary feeding and serum level of prolactin (PRL) in the two groups were estimated and compared after the patients had been treated for 5 days.
RESULTSThe cured and markedly effective rate in the treatment group was 89.7%, which was significantly higher than that in the control group (27.6%, P<0.05), 95% CI (0.1543, 0.2527). The improvement of TCM syndrome, elevation of milking volume, decrease of the supplementary feeding and increase of PRL level revealed in the treatment group were all superior to those in the control group, showing statistical significance (P<0.01).
CONCLUSIONAPSP shows an apparent efficacy in treating PCH and is worthy of application in clinical practice.

OBJECTIVES:
To explore the risk factors for hemorrhagic cystitis (HC) in children with β-thalassemia major (TM) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT).
METHODS:
A retrospective analysis was conducted on clinical data of 247 children with TM who underwent allo-HSCT at Shenzhen Children's Hospital from January 2021 to November 2022. The children were divided into an HC group (91 cases) and a non-HC group (156 cases) based on whether HC occurred after operation. Multivariable logistic regression analysis was used to explore the risk factors for HC, and the receiver operating characteristic curve was used to analyze the predictive efficacy of related factors for HC.
RESULTS:
Among the 247 TM patients who underwent allo-HSCT, the incidence of HC was 36.8% (91/247). Univariate analysis showed age, incompatible blood types between donors and recipients, occurrence of acute graft-versus-host disease (aGVHD), positive urine BK virus deoxyribonucleic acid (BKV-DNA), and ≥2 viral infections were associated with the development of HC after allo-HSCT (P<0.05). Multivariable analysis revealed that incompatible blood types between donors and recipients (OR=3.171, 95%CI: 1.538-6.539), occurrence of aGVHD (OR=2.581, 95%CI: 1.125-5.918), and positive urine BKV-DNA (OR=21.878, 95%CI: 9.633-49.687) were independent risk factors for HC in children with TM who underwent allo-HSCT. The receiver operating characteristic curve analysis showed that positive urine BKV-DNA alone or in combination with two other risk factors (occurrence of aGVHD, incompatible blood types between donors and recipients) had a certain accuracy in predicting the development of HC after allo-HSCT (area under the curve >0.8, P<0.05).
CONCLUSIONS
Incompatible blood types between donors and recipients, occurrence of aGVHD, and positive urine BKV-DNA are risk factors for HC after allo-HSCT in children with TM. Regular monitoring of urine BKV-DNA has a positive significance for early diagnosis and treatment of HC.

Objective:To investigate the prognostic value of serum free triiodothyronine (FT3) in patients with hepatitis E-related acute liver failure (HEV-ALF).Methods:Clinical data of 88 patients with HEV-ALF and 86 patients with acute hepatitis E (AHE) were collected from the member hospitals of Chinese Consortium for the Study of Hepatitis E between January 2016 and December 2021; the data of 100 health subjects who underwent health check-up in Suzhou Municipal Hospital were also collected as healthy control (HC) group. Serum FT3 levels were analyzed in all subjects. HEV-ALF patients were divided into survival group ( n=73) and death group ( n=15) according to their 30 day survival. Correlation between serum FT3 level and prognosis of HEV-ALF patients were analyzed by Cox regression and orthogonal partial least squares discriminant analysis (OPLS-DA). The receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were used to assess the predictive value of serum FT3 levels for predicting the prognosis of patients, and its prediction efficacy was compared with conventional Model for End-Stage Liver Disease (MELD), King’s College Hospital criteria (KCH) and Child-Pugh models. Results:The levels of serum FT3 in HEV-ALF patients were significantly lower than those in AHE patients and HC group ( P=0.006 or <0.001). Cox regression analysis showed that international standardized ratio ( HR=17.984, 95% CI 2.804-115.362), hepatic encephalopathy ( HR=12.895, 95% CI 2.386-69.695) and total cholesterol ( HR=2.448, 95% CI 1.108-5.409) were independent risk factors for death in HEV-ALF patients, and serum FT3 level ( HR=0.323, 95% CI 0.119-0.876) was a protective factor. OPLS-DA results showed serum FT3 levels had high predictive value. ROC curve analysis results showed that the area under the curve was 0.828 (95% CI 0.733-0.900, P<0.001), the sensitivity was 80.00%, and the specificity was 78.08%. DCA showed that FT3 has good prediction ability and decision-making level serum FT3 levels in patients with improvement and fluctuation were significantly higher than those in the patients with deterioration ( P<0.05 or <0.01). Conclusion:Serum FT3 levels are closely related to the prognosis of HEV-ALF patients and it may be used as a biomarker for the prognosis of patients with HEV-ALF.
