ObjectiveTo investigate the therapeutic effect of the water extract of Zanthoxylum bungeanum aqueous extract（ZBAE）on rheumatoid arthritis. MethodThe sixty SD rats were divided into normal group， model group ［complete Freund's adjuvant （CFA）， 10 mg·kg-1］， methotrexate（MTX） group （0.25 mg·kg-1）， low -， medium -， and high-dose ZBAE groups （90， 180， 360 mg·kg-1）. The rats in MTX group were given intraperitoneal injection for two weeks， three times a week， and the rats in ZBAE group were administrated for 14 days. The swelling of the ankle joint and body weight were observed， and arthritis scores were also performed. Computed tomography （CT）， hematoxylin-eosin （HE） staining and safranine-O and fast green staining were used to observe the effect of ZBAE on synovial hyperplasia and bone protection. Cell counting kit-8（CCK-8）method was used to detect the proliferation of the RA-FLSs cells treated with ZBAE. According to the results of CCK-8 experiment， the optimal concentration and time of administration were determined， blank group， low -， medium -， and high-dose ZBAE groups （0.08，0.10，0.12 g·L-1） were set up. The cell cycle distribution and apoptosis rate were analyzed by flow cytometry，the migration ability of RA-FLSs cells was examined by scratch test. Western blot was used to detect the effect of ZBAE on phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， cyclin-dependent kinase 2 （CDK2）， Cyclin A and phosphorylated PI3K， Akt （p-PI3K，p-Akt） protein expression in RA-FLSs cells. ResultCompared with the normal group，joint swelling index and arthritis score were increased in the model group （P<0.05），the bone of the ankle was seriously damaged， and there was obvious synovial hyperplasia. Compared with the model group， the ZBAE group could significantly reduce the joint swelling index （P<0.05）， inhibit synovial hyperplasia and cartilage destruction. In vitro study showed that compared with the blank group， ZBAE could inhibit the migration of RA-FLSs （P<0.05）， promoted cell apoptosis （P<0.05）， and acted on RA-FLSs cells in S phase to inhibit cell proliferation. Moreover， the result of Western blot showed that compared with the blank group， the expression of p-PI3K， p-Akt， CDK2 and Cyclin A proteins were significantly decreased in the high dose group of ZBAE （P<0.05）. ConclusionThese results suggest that ZBAE has a therapeutic effect on rheumatoid arthritis by inhibiting synovial hyperplasia， promoting synovial apoptosis and inhibiting its migration.

Cloning and expression analysis of JrGI gene in walnut / 生物工程学报

GI (GIGANTEA) is one of the output key genes for circadian clock in the plant. The JrGI gene was cloned and its expression in different tissues was analyzed to facilitate the functional research of JrGI. RT-PCR (reverse transcription-polymerase chain reaction) was used to clone JrGI gene in present study. This gene was then analyzed by bioinformatics, subcellular localization and gene expression. The coding sequence (CDS) full length of JrGI gene was 3 516 bp, encoding 1 171 amino acids with a molecular mass of 128.60 kDa and a theoretical isoelectric point of 6.13. It was a hydrophilic protein. Phylogenetic analysis showed that JrGI of 'Xinxin 2' was highly homologous to GI of Populus euphratica. The result of subcellular localization showed that JrGI protein was located in nucleus. The JrGI, JrCO and JrFT genes in female flower buds undifferentiated and early differentiated of 'Xinxin 2' were analyzed by RT-qPCR (real-time quantitative PCR). The results showed that the expression of JrGI, JrCO and JrFT genes were the highest on morphological differentiation, implying the temporal and special regulation of JrGI in the differential process of female flower buds of'Xinxin 2'. In addition, RT-qPCR analysis showed that JrGI gene was expressed in all tissues examined, whereas the expression level in leaves was the highest. It is suggested that JrGI gene plays a key role in the development of walnut leaves.

Clinical analysis of liver dysfunction induced by SHR-1210 alone or combined with apatinib and chemotherapy in patients with advanced esophageal squamous cell carcinoma / 中华肿瘤杂志

Objective: To investigate the clinical characteristics of abnormal liver function in patients with advanced esophageal squamous carcinoma treated with programmed death-1 (PD-1) antibody SHR-1210 alone or in combination with apatinib and chemotherapy. Methods: Clinical data of 73 patients with esophageal squamous carcinoma from 2 prospective clinical studies conducted at the Cancer Hospital Chinese Academy of Medical Sciences from May 11, 2016, to November 19, 2019, were analyzed, and logistic regression analysis was used for the analysis of influencing factors. Results: Of the 73 patients, 35 had abnormal liver function. 13 of the 43 patients treated with PD-1 antibody monotherapy (PD-1 monotherapy group) had abnormal liver function, and the median time to first abnormal liver function was 55 days. Of the 30 patients treated with PD-1 antibody in combination with apatinib and chemotherapy (PD-1 combination group), 22 had abnormal liver function, and the median time to first abnormal liver function was 41 days. Of the 35 patients with abnormal liver function, 2 had clinical symptoms, including malaise and loss of appetite, and 1 had jaundice. 28 of the 35 patients with abnormal liver function returned to normal and 7 improved to grade 1, and none of the patients had serious life-threatening or fatal liver function abnormalities. Combination therapy was a risk factor for patients to develop abnormal liver function (P=0.007). Conclusions: Most of the liver function abnormalities that occur during treatment with PD-1 antibody SHR-1210 alone or in combination with apatinib and chemotherapy are mild, and liver function can return to normal or improve with symptomatic treatment. For patients who receive PD-1 antibody in combination with targeted therapy and chemotherapy and have a history of long-term previous smoking, alcohol consumption and hepatitis B virus infection, liver function should be monitored and actively managed in a timely manner.

Action Mechanism of Chinese Medicine Polysaccharides in Prevention and Treatment Diabetes and Its Complications：A Review / 中国实验方剂学杂志

Diabetes is a metabolic disease mainly characterized by hyperglycemia due to inadequate insulin secretion. And persistent hyperglycemia can cause chronic damage or dysfunction of eyes， kidneys， heart， blood vessels and nerves. Polysaccharides are high molecular carbohydrates polymerized by glycosidic bonds from more than 10 monosaccharide molecules of the same or different types. They have the advantages of wide sources， high safety and low toxic and so on. As one of the important effective components of traditional Chinese medicine， polysaccharides have biological activities such as immune regulation， anti-oxidation， anti-tumor， lowering blood sugar and so on. The structure is directly related to biological activities， and the advanced structure of polysaccharides is based on the primary structure. Exploring the primary structure of polysaccharides is the key task of lowering blood sugar and improving diabetic complications. This paper summarizes the monosaccharide composition of the primary structure of Chinese medicine polysaccharides， and the mechanism of Chinese medicine polysaccharides improving diabetes is emphasized by increasing the secretion and release of insulin， increasing the islet β cell number， upregulating insulin receptor level， improving glucose and lipid metabolism， inhibiting inflammatory response， improving oxidative stress and regulating phosphatidylinositol-3-kinase（PI3K）/protein kinase B （Akt）， mitogen activated protein kinase， cyclic adenosine monophosphate（cAMP）/protein kinase A（PKA） and adenosine monophosphate activated protein kinase（AMPK） signaling pathways. At the same time， we also summarized the prevention and treatment of Chinese medicine polysaccharides in diabetic nephropathy， diabetic cardiomyopathy， diabetic ophthalmopathy and diabetic peripheral neuropathy， in order to provide a theoretical basis for new drug development and clinical application of Chinese medicine polysaccharides in the intervention of diabetes and its complications.

ObjectiveTo observe the clinical efficacy and safety of Chinese medicinal mixture for dispelling stasis and resolving phlegm combined with western medicine in the treatment of epilepsy combined with cognitive impairment by randomized， double-blind， placebo-controlled， parallel-group trial. MethodA total of 123 inpatients and outpatients with epilepsy complicated with cognitive impairment admitted to the department of neurology at Longhua Hospital from October 2020 to October 2021 were randomly assigned into a control group （62 cases， carbamazepine + placebo） and a treatment group （61 cases， carbamazepine + Quyu Dingxian Zhengtong mixture） by random number table method. In the treatment group， 4 cases were exfoliated and eliminated. In the control group， 3 cases fell off. Finally， 57 cases in the treatment group and 59 cases in the control group were included. The total course of treatment for both groups was 12 weeks. The clinical efficacy， efficacy for traditional Chinese medicine （TCM） syndromes， and incidence of adverse reactions were compared between two groups. The changes of seizure frequency， abnormal rate of electroencephalogram （EEG）， cognitive function score， serum homocysteine （HCY）， folic acid， and vitamin B12 （B12） were measured and compared before and after treatment. ResultAfter 12 weeks of treatment， the treatment group had higher clinical efficacy ［92.98% （53/57） vs 79.66% （47/59）， χ2=4.327， P<0.05］ and efficacy for TCM syndromes ［96.49% （55/57） vs 84.75% （50/59）， χ2=4.660， P<0.05］ than the control group. The treatment group was superior to the control group in reducing the seizure frequency （Z=-3.938， P<0.01） and improving the Montreal cognitive assessment （MoCA） score （t=4.333， P<0.01） and mini-mental state examination （MMSE） score （t=9.531， P<0.01）. The variations in serum HCY， folic acid， and B12 in the treatment group were less than those in the control group （t=-7.233， t=-7.972， t=-6.871， P<0.01）. After treatment， the abnormal rate of EEG in the treatment group was lower than that in the control group （χ2=4.437， P<0.05）. The incidence of adverse reactions in the treatment group （1.75%， 1/57） was lower than that （13.56%， 8/59） in the control group （corrected χ2=4.116， P<0.05）. ConclusionChinese medicinal mixture for dispelling stasis and resolving phlegm in combination with western medicine had better efficacy and safety than western medicine alone in the treatment of epilepsy complicated with cognitive impairment. Specifically， the combination outperformed western medicine alone in terms of clinical efficacy， efficacy for TCM syndromes， reduction in seizure frequency， abnormal rate of EEG， adverse reactions， improvement of cognitive function， and variations in serum folic acid， B12， and HCY values. Chinese medicinal mixture for dispelling stasis and resolving phlegm may improve the clinical efficacy and safety by changing the metabolism of folic acid， B12， and HCY in serum of the patients with epilepsy complicated with cognitive impairment.

Two cases of Cornelia de Lange syndrome type 2 for SMC1A gene mutations / 中华实用儿科临床杂志

The clinical features and gene mutation characteristics of 2 children who suffered from Cornelia de Lange syndrome(CdLs)and were admitted to Affiliated Hospital of Zunyi Medical University in March 2019 were retrospectively analyzed.The 2 cases developed in infancy and presented with intractable epilepsy were accompanied with developmental retardation and special appearance.It was obvious that the 2 children had SMC1A gene mutations on X chromosome.Case 1 was frameshift mutations in the SMC1A gene at c. 2561dupA(p.K854fs), and case 2 was mutations in the SMC1A gene at c. 3441+ 1G>A(exon24)splicing mutation.These were heterozygous de novo mutations, and weren′t detected in their parents, which was not reported in literatures.In this study, 2 cases of CdLs were caused by SMC1A gene mutation, which enriched the human gene mutation database.CdLs should be considered in children with early-onset epilepsy, especially appearance and developmental retardation.Genetic testing is the most important diagnostic method.

Evaluation the triage performance of p16/Ki-67 dual staining for HR-HPV positive women / 中华预防医学杂志

This study aimed to evaluate the clinical performance of p16/Ki-67 dual staining for triage high risk HPV (HR-HPV) infected women. Target objects were women who infected HR-HPV and received colposcopy examination between April and December of 2016 at the Second Affiliated Hospital of Zhengzhou University. Gynecologists collected the cervical exfoliated cells from eligible women for p16/Ki-67 dual staining, LBC testing and HPV DNA testing. Histology diagnosis were used as gold standard. Sensitivities, specificities, positive predictive values (PPVs), negative predictive values (NPVs) of p16/Ki-67 dual staining, LBC testing and HPV16/18 testing for triage of HR-HPV positive population were calculated and compared. A total of 295 HR-HPV infected women were selected, and the mean age was (44.29±11.48) years old. Positive rates of p16/Ki-67 dual staining, HPV16/18 testing and LBC testing were 70.17% (207), 56.95% (168) and 85.76% (253), respectively. When CIN2+as the endpoint, among the three triage methods, sensitivity of p16/Ki-67 dual staining was 90.00% (95: 85.06%-93.43%), higher than the value of HPV 16/18 testing, but lower than the value of LBC testing. Specificity, PPV and NPV of p16/Ki-67 dual staining were the highest [71.58% (95: 61.81%-79.67%), 86.96% (95:81.69%-90.88%) and 77.27% (95: 67.49%-84.78%)]. When detection for CIN3+, sensitivity of p16/Ki-67 dual staining was 92.90% (95: 87.74%-95.99%), lower than the value of LBC testing, but higher than the value of HPV16/18 testing. Specificity of p16/Ki-67 dual staining was 55.00% (95: 46.74%-63.00%), lower than the value of HPV16/18 testing, but higher than the value of LBC testing. PPV of p16/Ki-67 dual staining was 69.57% (95: 62.99%-75.43%), lower than the value of HPV 16/18 testing, but higher than the value of LBC testing. NPV of p16/Ki-67 dual staining was 87.50% (95: 78.99%-92.87%), higher than value of HPV 16/18 testing, but lower than the value of LBC testing. p16/Ki-67 dual staining has better clinical effects than HPV 16/18 testing and LBC testing for triage women with HR-HPV infection.

Overexpression of CircRNA BCRC4 Regulates Cell Apoptosis and MicroRNA-101/EZH2 Signaling in Bladder Cancer / 华中科技大学学报（医学）（英德文版）

Emerging evidence has indicated that circular RNAs (circRNAs) play pivotal roles in the regulation of cellular processes and are found to be aberrantly expressed in a variety of tumors.However,the clinical role of circRNAs in bladder cancer (BC) and the molecular mechanisms have yet to be fully understood.In this study,the clinical specimens were obtained and the expression level of a circRNA BCRC4 was detected by real-time PCR in both BC tissues and cell line.The circular RNA over-expression plasmid was constructed and transfected into BC cells and related cell line.The cell cycles and apoptosis were observed using inverted microscope and flow cytometry.Western blotting was used to compare the relative protein expression of groups with different treatments.It was found that circRNA BCRC4 expression was lower in BC tissues than in adjacent normal tissues.Furthermore,consequences of fomed-expression of BCRC4 promoted apoptosis and inhibited viability of T24T and UMUC3 cells,and up-regulated BCRC4-inereased miR-101 level,which suppressed EZH2 expression in both RNA and protein levels.In addition,gambogic acid (GA) is a promising natural anticancer compound for BC therapy,and GA treatment increased the BCRC4 expression in T24T and UMUC3 cells in a dose-dependent manner.Altogether,our findings suggest that BCRC4 functions as a tumor suppressor in BC,and mediates anticancer function,at least in part,by up-regulating the expression of miR-101.Targeting this newly identified circRNA may help us develop a novel strategy for treating human BC.

The course of the treatment was 4 weeks in the two groups, and the 3-month follow-up was given after the course was finished, for comparing the clinical symptoms, results of colon transit tests, scores of depression/anxiety scale and nursing satisfaction. Results: The total effective rate was 92.3% in the observation group and 69.2% in the control group, with a significant difference between the two groups. After the treatment and during the follow-up checks, the scores of Chinese medical symptoms in the two groups were remarkably decreased than those before the treatment (all P<0.01); the scores of the observation group were obviously lower than those in the control group (all P<0.01). The discharge rates of the markers in the two groups were remarkably increased than those at the same time period before the treatment; moreover, the discharge rates of the markers at various time periods were remarkably better in the observation group than those in the control group (P<0.01). SDS and SAS scores were remarkably decreased after the treatment in the two groups (P<0.01). In comparison of SDS score between the two groups after the treatment, the difference was statistically significant (P<0.01). In comparison of SAS score between the two groups after the treatment, the difference was statistically significant (P<0.05). The nursing satisfaction was 96.2% in the observation group after the treatment, obviously better than that in the control group (73.1%). The recurrence rate was 8.3% in the observation group, remarkably lower than that in the control group (33.3%). Conclusion: Moxibustion at the abdominal acupoints plus routine nursing can remarkably improve the colon transit functions and anxious and depressive emotion in patients with STC, and the therapeutic effects are remarkable. Not only the clinical satisfaction is higher, but the recurrence rate is obviously lower than that of routine nursing.

Secondary male hypogonadism induced by sellar space-occupying lesion: Clinical analysis of 22 cases / 中华男科学杂志

<p><b>Objective</b>To analyze the clinical characteristics of secondary male hypogonadism induced by sellar space-occupying lesion, explore its pathogenesis, and improve its diagnosis and treatment.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data about 22 cases of secondary male hypogonadism induced by sellar space-occupying lesion, reviewed related literature, and investigated the clinical manifestation, etiological factors, and treatment methods of the disease. Hypogonadism developed in 10 of the patients before surgery and radiotherapy (group A) and in the other 12 after it (group B). The patients received endocrine therapy with Andriol (n=7) or hCG (n=15).</p><p><b>RESULTS</b>The average diameter of the sellar space-occupying lesions was significantly longer in group A than in B (［2.35±0.71］ vs ［1.83±0.36］ cm, P<0.05) and the incidence rate of prolactinomas was markedly higher in the former than in the latter group (60% vs 0, P<0.01). The levels of lutein hormone (LH), follicle stimulating hormone (FSH) and testosterone (T) were remarkably decreased in group B after surgery and radiotherapy (P<0.01). Compared with the parameters obtained before endocrine therapy, all the patients showed significant increases after intervention with Andriol or hCG in the T level (［0.78±0.40］ vs ［2.71±0.70］ ng/ml with Andriol; ［0.93±0.44］ vs ［3.07±0.67］ ng/ml with hCG) and IIEF-5 score (5.00±2.61 vs 14.50±3.62 with Andriol; 5.36±1.82 vs 15.07±3.27 with hCG) (all P<0.01). The testis volume increased and pubic hair began to grow in those with hypoevolutism. The patients treated with hCG showed a significantly increased testis volume (P<0.01) and sperm was detected in 7 of them, whose baseline testis volume was markedly larger than those that failed to produce sperm (［11.5±2.3］ vs ［7.5±2.3］ ml, P<0.01). Those treated with Andriol exhibited no significant difference in the testis volume before and after intervention and produced no sperm, either.</p><p><b>CONCLUSIONS</b>Hypothyroidism might be attributed to surgery- or radiotherapy-induced damage to the pituitary tissue, space-occupying effect of sellar lesion, and hyperprolactinemia. Both Andriol and hCG can improve the T level and erectile function, but the former does not help spermatogenesis.</p>

Relationship of abnormal sperm DNA methylation with early spontaneous abortion / 中华男科学杂志

<p><b>Objective</b>To investigate the relationship between the abnormal sperm DNA methylation level and early spontaneous abortion.</p><p><b>METHODS</b>We randomly selected 98 males who met the inclusion criteria and whose wives suffered from unexplained abortion or embryo abortion, and included another 46 normal healthy men present for pre-pregnancy check-up as controls. We examined the semen quality and sperm morphology, obtained the sperm DNA fragmentation index (DFI) by modified sperm chromatin dispersion, and measured the sperm DNA methylation level using the methylated DNA quantification kit and the colorimetric method.</p><p><b>RESULTS</b>Compared with the normal controls, the men in the unexplained abortion group showed a significantly lower rate of big-halo sperm (［45.50 ± 26.27］ vs ［36.49 ± 23.06］%, P = 0.038), a higher rate of abnormal-head sperm (［77.08± 12.21］ vs ［81.09± 10.89］%, P = 0.049), and a lower level of sperm DNA methylation (［0.47 ± 0.33］ vs ［0.36 ± 0.26］ ng/μl, P = 0.035). The sperm DNA methylation level was positively correlated with the percentage of big-halo sperm (OR=0.546, P<0.01). Multivariate regression analysis manifested that sperm head abnormality was an independent risk factor of early spontaneous abortion or embryo abortion (OR=1.032, P = 0.049), while the high methylation level was protective factor against early spontaneous abortion or embryo abortion (OR=0.244, P = 0.03).</p><p><b>CONCLUSIONS</b>The abnormal level of sperm DNA methylation may be one of the important reasons for early spontaneous abortion or embryo abortion.</p>
