Objective To observe the effect of the modified Yulin Decoction on improving the living quality of patients with yang-deficiency of the spleen and kidney of premature ovarian failure. Methods One hundred and twenty-seven patients were divided into experimental group (80) and control group (47) by non-randomized noninferiority comparative study. The experimental group was treated with modified Yulin Decoction daily orally once a day. The control group was treated with oral estradiol valerate and progesterone cycle. Two groups received continuous medication for 21 d, and treatment interval was 5 d. Three cycles of treatment were set as one course, and treated for 2 courses. The SF-36 scale was used to calculate the total scores and scores of eight dimensions before and after treatment. Results Before treatment, there was no significant difference (P>0.05) in the scores of SF-36 dimensions (except somatic pain) and total score between the two groups. Compared with before treatment, the score and total score of SF-36 in the experimental group increased (P<0.05, P<0.01). The mental health score of the control group was higher than that of before treatment (P<0.05, P<0.01). After treatment, there was statistical significance in the two dimensions of vitality and mental health in the two groups (P<0.05). There were significant differences (P<0.01) in the total score and scores of SF-36 physiological function, physical pain, general health, vigor, social function, emotional function and mental health between the two groups. Conclusion Modified Yulin Decoction can improve the living quality of patients with yang-deficiency of the spleen and kidney of premature ovarian failure.

OBJECTIVE:To regulate the management of operation drug and promote medication security. METHODS:Based on the relevant principles in the standard of JCI,the practice about establishment of operation pharmacy in our hospital was intro-duced,and it were stated from two aspects which included working mode and effects. RESULTS:The working mode were format-ed by definiting the duties and working flow of pharmacist,anesthetist and liaison man. The establishment of operation pharmacy, which brought operation drugs into the unified management system of our hospital,saved manpower and improved work efficien-cy,refined the management of drugs in all aspects,improved the management of drug safety level,strengthened drug expiration date management,implemented the reporting of adverse drug reactions(event)and collecting of medication(potential)errors. The established mode conformed to the relative standard of JCI including preparation,grant,storage and collection of ADR of drug. CONCLUSIONS:The established drug management of operation pharmacy promotes standardized administration of surgery drug, which guarantees the drug use safety of patients.

Aim To confirm the inhibitory effect of chronic intermittent hypobaric hypoxia ( CIHH) on my-ocardial apoptosis induced by metabolism syndrome ( MS) , and to investigate its mechanism. Methods A rat model of MS induced by fructose was used. The blood pressure and the plasma content of glucose, tri-glyceride, cholesterol, and insulin after 12 h fasting were detected. HE stain were used to detect the cardi-ac structure. The TUNEL staining and activity of caspase-3 were used to detect the apoptosis of myocar-dium. The protein expression of Bcl-2 and Bax was detected by Western blot . Results Compared with the control rats, the blood pressure and the plasma content of glucose, triglyceride, cholesterol, and insu-lin were all increased in rats with MS. In rats with MS, the impairment of cardiac structure and the increase of apoptosis were also observed. The protein expression of Bcl-2 was significantly down-regulated, and that of Bax was significantly up-regulated in MS rats. The ratio of Bcl-2/Bax was also significantly decreased. Interest-ingly, CIHH could ameliorate all of the above issues. There was no significant difference between control group and CIHH group. Conclusion CIHH may im-prove the increased apoptosis in rats with MS via inhib-iting the mitochondrial pathway of apoptosis. This stud-y might provide new targets for therapy and the preven-tion of MS patients.

Objective To investigate the association between the six single nucleotide polymorphisms ( SNP),named as rs179247,rsl2101261,rs2284722,rs4903964,rs2300525,rsl7111394 in the intron 1 of thyroid stimulating hormone receptor gene (TSHR) and Graves' disease (GD).MethodsThe genotypes of the six SNPs were genotyped by Taqman probe technique on Fluidigm EP1 platform in 618 GD patients and 646 control subjects.Meanwhile,TSH receptor antibodies (TRAb) of the patients were determined.ResultsAmong the six SNPs,five S NPs were strongly associated with GD,with the most signals at rs179247_G,rs12101261_C,rs4903964 _G (P=2.85×10-10,OR=1.73,95％CI1.46-2.05;P=1.74×10-10,OR=1.73,95％CI 1.46-2.05;P=2.24×10-10,OR=1.69,95％ CI 1.44-1.99 ).The results of logistic regression analysis indicated that rs12101261 and rs4903964 were main susceptibility loci of GD in the intron 1 of TSHR.rs179247_G,rs1210126 1_C,and rs4903964_G were associated with subset of the GD patients with positive TRAb (P=4.24× 10-13,p=5.48× 10-13,P =3.89×10-12 ).Conclusionrs179247,rs12101261,and rs4903964 in TSHR intron 1 were significantly associated with GD in the Chinese Han population from Bengbu city.rs12101261 and rs4903964 were the major susceptibility SNPs associated with GD.TSHR gene may play a main role of susceptibility gene in the subset of GD patients with persistent positive TRAb.

BACKGROUND: At present, there is evidence that domestic porous tantalum has good biocompatibility and osteogenic properties, but the specific osteogenic mechanism and its effect on osteogenic factors are still unclear. OBJECTIVE: To observe the effects of domestic porous tantalum materials on the expression of collagen type I, tissue transglutaminase-2 and calcium-binding protein A4 in MG63 cells. METHODS: MG63 cells in logarithmic growth phase were inoculated onto 24-well plates and cultured in three groups: in blank group, conventional medium was added; in tantalum extract group, porous tantalum material extract was added; and in tantalum scaffold group, porous tantalum material and conventional medium were added. On 1, 3, 5, 7 and 9 days of culture, the cell proliferation of each group was detected by cell counting kit-8 method. On 5 days of culture, the levels of collagen type I, tissue transglutaminase-2 and calcium-binding protein A4 secreted by MG63 cells in each group were detected by ELISA. Western blot assay was used to detect the expression of three proteins in each group. RESULTS AND CONCLUSION: (1) With the prolongation of culture time, the number of cells in each group increased gradually. There was no difference in cell proliferation among the three groups at different time points (P> 0.05). (2) The secretory levels of collagen type I and tissue transglutaminase-2 in the tantalum scaffold group were significantly higher than those in the blank group and tantalum extract group (P < 0.05), while the secretion of collagen type I and tissue transglutaminase-2 in the tantalum extract group was significantly higher than that in the blank group (P < 0.05). The secretion of calcium-binding protein A4 in the tantalum scaffold group was significantly lower than that in the other two groups (P < 0.05). (3) The expression of collagen type I and tissue transglutaminase-2 protein in the tantalum scaffold group was significantly higher than that in the blank group and tantalum extract group (P < 0.05), while the expression of collagen type I and tissue transglutaminase-2 protein in the tantalum extract group was significantly higher than that in the blank group (P < 0.05). The expression of calcium-binding protein A4 in the tantalum scaffold group was significantly lower than that in the blank group and tantalum extract group (P < 0.05). To conclude, domestic porous tantalum materials could promote the secretion of collagen type I and tissue transglutaminase-2 by MG63 cells, and inhibit the secretion of calcium-binding protein A4.

OBJECTIVETo estimate the reference value for micronucleus frequency of peripheral blood lymphocytes in general Chinese population, and to guide the genotoxicity evaluation and risk analysis for populations exposed to environmental or occupational chemicals.

METHODSA fulltext search was performed in CNKI with the key words of "micronucleus" and "human", and PubMed was searched with "cytokinesis-block micronucleus","CBMN","humans", and "adults", to obtain the articles published at home and abroad from 2001 to 2014 in which cytokinesis-block micronucleus (CBMN)assay was applied for micronucleus detection and populations not exposed to genotoxins were established as a control. Monte Carlo simulation was performed based on the micronucleus frequency, standard deviation, and sample size provided in these articles to calculate the micronucleus frequency for general population and to analyze the influence of sex, smoking, and drinking on micronucleus frequency.

RESULTSA total of 23 articles were included in the final analysis. The minimum mean micronucleus frequency was 0.39‰, and the maximum mean micronucleus frequency was 25.3‰. There were 1623 subjects in the control group in total (range 22~178, mean 70.6). Monte Carlo simulation was performed 100 times, and the mode of micronucleus frequency was 0 or 1‰; the values of P0, P25, P50 , P75, and P95 were 0‰, 1‰, 2‰~3‰, 5‰~6‰, and 14‰~19‰, respectively; the mean value was 4.36‰(range 4.22‰~4.57‰). With the application of one-sided 95% range(x±1.64 s), the upper limit of the range of reference value was calculated to be 13.46‰~14.75‰.

CONCLUSIONThe micronucleus frequency of peripheral blood lymphocytes in general Chinese population is 4.36‰, the interquartile range is 1‰~5‰ or 1‰~6‰, and the upper limit of reference value is 14.17‰. The factors of living area, sex, smoking, and drinking may influence micronucleus frequency.

OBJECTIVE: To explore the genetic etiology for a Chinese pedigree affected with Lesch-Nyhan syndrome. METHODS: Members of the pedigree who had visited the Genetic Counseling Clinic of Linyi People's Hospital on February 10, 2022 were selected as the study subjects. Clinical data and family history of the proband were collected, and trio-whole exome sequencing (trio-WES) was carried out for the proband and his parents. Candidate variants were verified by Sanger sequencing. RESULTS: Trio-WES revealed that both the proband and his cousin brother had harbored a hemizygous c.385-1G>C variant in intron 4 of the HPRT1 gene, which was unreported previously. A heterozygous c.385-1G>C variant of the HPRT1 gene was also found in the proband's mother, grandmother, two aunts, and a female cousin, whilst all phenotypically normal males in his pedigree were found to have a wild type for the locus, which has conformed to an X-linked recessive inheritance. CONCLUSION The heterozygous c.385-1G>C variant of the HPRT1 gene probably underlay the Lesch-Nyhan syndrome in this pedigree.

Objective To investigate the clinical and histopathologic characteristics, diagnosis, differential diagnosis and prognostic features of anastomosing hemangioma.Methods Five cases of anastomosing hemangioma of the kidney and adrenal gland were collected, the clinical and radiologic features, histomorphology, immunophenotype and prognosis were analyzed with review of literature.Results Three patients were male and two were female with ages ranging from 47 to 77 years; three were located in adrenal gland and 2 originated from the kidney.Clinically, 4 tumors were incidentally identified, 1 presented as edema of lower extremity.By radiography, all presented as a well-demarcated, oval, solid and low-density mass.Grossly, the tumors ranged in maximum diameter from 1.6 to 2.5 cm ( mean 2.1 cm) .Microscopically, the tumors consisted of anastomosing sinusoidal capillary-sized vessels lined by a single layer of flattened, cubical to hobnail endothelial cells, setting in an pauci-cellular stroma of edematous and hyaline changes.Other commonly seen features included vaguely lobular growth pattern ( 3/5 ) , hemorrhage and thrombosis ( 5/5 ) , intravascular growth pattern ( 5/5 ) , eosinophilic intracytoplasmic hyaline globules ( 1/5 ) and extramedullary hematopoiesis ( 3/5 ).The tumor cells were typically bland-appearing and mitoses were scarce, with 1 case demonstrating cellular foci of tumor with slight pleomorphism and increased mitoses ( 2/50 HPF ).Immunohistochemical studies showed the tumor cells expressed endothelial cells markers.Follow-up information was available for all 5 patients and showed no evidence of tumor recurrence or metastasis within 6 to 52 months ( mean 30 months).Conclusions Anastomosing hemangioma is a rare, benign subtype of capillary hemangioma that predominantly affects the urologic organs and adrenal glands;it is needed to distinguish it histologically from a series of benign or malignant tumors that feature a richly vascular stroma.Careful attentions to its characteristic morphology with the judicious use of immunohistochemistry can help distinguish this tumor from its many mimickers.

Objective:To explore the efficacy of PVP combined with zoledronic acid in the treatment of postmenopausal osteoporotic vertebral fractures.Method:90 patients with postmenopausal osteoporotic vertebral fractures treated in our hospital from Jul. 2018 to Aug. 2020 were selected. According to different treatment methods, the patients were divided into observation group and control group. The patients in both groups were treated with PVP. The patients in the control group were given oral alendronate, calcitriol capsules and calcium, and the patients in the observation group were given zoledronic acid injection, calcitriol capsules and calcium were taken orally for 1 year. BMD of lumbar spine, femoral neck, greater trochanter and ward triangle, lumbar ODI index and VAS score, serum BGP and β-CTX, PINP levels and adverse reactions during treatment. Results:One year after operation, the lumbar ODI index and VAS score of the observation group were significantly lower than those of the control group ( P<0.05), and the BMD of lumbar spine, femoral neck, greater trochanter and ward triangle were higher than those of the control group ( P<0.05). The levels of serum BGP, β-CTX and PINP levels in the two groups were significantly higher than those in the control group ( P<0.05) . Conclusion:Zoledronic acid can significantly improve bone metabolism, accelerate bone formation, increase BMD, reduce low back pain and improve lumbar function in patients with osteoporotic vertebral compression fracture after PVP.

Objective: To investigate the clinicopathologic and differential diagnostic features of glomus tumor of the kidney. Methods: Four cases of glomus tumor of the kidney were collected from the archives of Peking University Third Hospital, the Second Hospital of Tianjin Medical University, Ningbo Yinzhou Second Hospital and Zhejiang Provincial People′s Hospital between January 2012 to June 2017; the clinical and radiologic features, histomorphology, immunohistochemistry, ultrastucture and prognosis were analyzed and the relevant literature was reviewed. Results: Patients consisted of 2 men and 2 women with ages ranging from 37 years to 66 years (mean 55 years). Three patients had history of hypertensive disease (grade Ⅱ, 3 to 10 years). The tumors measured in maximum diameter from 3.0 cm to 4.0 cm (mean 3.6 cm) and showed gray-white to yellow and tan on cut surface. Macroscopical examinations showed all tumors were circumscribed but non-encapsulated. Histologically, 1 tumor presented as glomus tumor with extensive myxoid change, 1 as cellular and solid pattern glomus tumor, 1 as glomangioma with focal myopericytoma-like pattern and 1 as symplastic glomus tumor with areas resembling myopericytoma. The tumor cells in two cases showed scant cytoplasm and uniform, bland-appearing nuclei without mitoses. In one case, the tumor cells were epithelioid with abundant eosinophilic cytoplasm and relatively well-defined cell borders. There was an increased mitosis of 4/50 HPF; however, no evidence of atypical mitosis or nuclear atypia was noted. In the symplastic glomus tumor the tumor cells showed frequently nuclear pleomorphism without mitoses. By immunohistochemistry, all tumors showed strong and diffuse reactivities to at least 3 of the 4 muscle-associated markers (SMA, h-Caldesmon, MSA and Calponin), 3 tumors strongly and diffusely expressed collagen Ⅳ, 2 expressed CD34 and 1 focally expressed desmin; whereas markers including epithelial, neuroendocrine, nephrogenic, melanoma-associated, STAT6, S-100 protein, CD117 and β-catenin all were negative in all the 4 tumors. Ultrastuctural analysis was done in 2 cases and showed prominent cytoplasmic actin bundles and pericellular basement membrane, and lacking of rhomboid renin crystals in both tumors. The hypertension persisted after surgical resection for all the 3 patients with this medical history. Follow-up information (range: 6-64 months, mean: 44 months)showed that no evidence of local recurrence or distant metastasis was identified in all 4 patients. Conclusions Glomus tumor rarely occurs in the kidney and usually has a good prognosis. Careful attention to its morphology with the judicious use of immunohistochemistry and ultrastuctural analysis can be helpful for its diagnosis and differential diagnosis.
