Objective To evaluate the accuracy and sensitivity of three techniques in the diagnosis of renal diseases following multiple myeloma. Methods 41 serum samples from the kidney-damaged patients with multiple myeloma and 36 from the control group with general renal diseases were detected by quantitative analysis of immunoglobulins, serum protein electrophoresis and serum Immunofixation Electrophoresis. The accuracy and sensitivity of the three techniques were analysed by Two-way ANOVA and Multiple Comparisons of the check-out rate of monoclonal immunoglobulin. Results No monoclonal components were checked out by quantitative analysis of immunoglobulins. The checkout rate of IgG and IgM myelomas were 100% by serum protein electrophoresis, which had application limit on other types of myelomas. Whereas all secretarial myelomas could be diagnosed and typied by Immunofixation Electrophoresis, the sensitivity and accuracy was 100%, there was no false positive in the control group. Comparing with quantitative analysis of immunoglobulins and serum protein electrophoresis, serum Immunofixation electrophoresis had higher sensitivity and accuracy in diagnosis of renal diseases following multiple myeloma ( P

OBJECTIVE:To study the effect of Zuogui pill on the expression of gap junction protein 43(Cx43)in ovarian tis-sue of mice with premature ovarian failure(POF)induced by intraperitoneal injection of cyclophosphamide(CTX),and explore its mechanism in the treatment of chemotherapy-induced POF. METHODS:72 mice were randomly divided into blank group,model group,Estradiol valerate tablet group (positive control,0.00013 g/kg),Zuogui pill low-dose,medium-dose,high-dose groups (13.65,40.95,122.85 g/kg)by body mass,10 in each group. Except for blank group,other groups were reduce POF model by ip CTX,once a day,for 20 d. Meanwhile,the mice were intragastrically administrated related medicines,once a day,for 30 d. After 2 h of last administration,reverse transcription-polymerase chain reaction method and Western blot method were used to detect the Cx43 mRNA and protein expressions in ovarian tissue respectively,and immunohistochemistry method was adopted to detect the distribution of Cx43 protein in ovarian tissue. RESULTS:Compared with blank group,Cx43 mRNA and protein expressions in ovarian tissue of mice in model group were obviously weakened,and the distribution of Cx43 protein in follicle and granulocytes were obviously reduced(P<0.01). Compared with model group,Cx43 mRNA and protein expressions in ovarian tissue of mice in Estradiol valerate tablet group and Zuogui pill medium-dose,high-dose groups were obviously strengthened,and the distribution of Cx43 protein in follicle and granulocytes were obviously increased(P<0.01). CONCLUSIONS:Zuogui pill can increase the Cx43 mRNA and protein expressions in ovarian tissue of CTX-induced POF mice,increase the distribution of Cx43 in follicle and granu-locytes and gap junction function,which may be one of the treatment mechanism of POF.

OBJECTIVETo analyse clinical feasibility of two electrophoresis procedures of seminal plasma proteins, agarose gel electrophoresis and SDS-agarose gel electrophoresis.

METHODSSixty-nine semen samples were examined and classified into three groups: the asthenozoospermia (n = 22), the asthenoteratozoospermia (n = 19), and the relative normal group (n = 28) with normal routine and special test results, according to WHO routine and special test criterion. Then, the seminal plasma protenis were separated by two different electrophoresis, with SDS-agarose and agarose support medium, the buffer pH 7.0 and 9.2 respectively. The agarose gel electrophoresis was done under various sample loading time, motion power and staining modules. The completed gels were scanned and compared the each other statistically.

RESULTSSeminal plasma proteins can be separated into 4 strips by SDS-agarose gel electrophoresis with acid crystal violet, and the strips were diffusion and with dark background. However, 6 clear strips named A, B, C, D, E, and F can be obtained by agarose gel electrophoresis with 6 min. After samples were loaded and stained by amidoblack, there showed appropriate spaces among strips, and it was very easy to scan the drying gel by a densitometer. Using agarose gel electrophoresis, the statistical difference in strip C and E was shown between the asthenozoospermia and the relative normal group, and between the asthenozoospermia and the asthenoteratozoospermia, however, not between the relative normal and the asthenoteratozoospermia group. Moreover, the samples in the relative normal group with normal routine and special test results were in different electrophoresis maps.

CONCLUSIONAgarose gel electrophoresis of seminal plasma proteins with buffer pH 9.2, 6 min. sample loading and amidoblack stain was a simple, fast and fit technique for clinic.

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 analyse protein alterations in the seminal plasma of non-obstructive azoospermia patients.

METHODSSemen samples were collected from 11 healthy fertile and 6 azoospermia male volunteers respectively and tested by SELDI-TOF-MS with CM10 protein chip to get protein spectra maps, which were automatically treated with the special softwares of Ciphergen Inc.

RESULTSThe mean peak heights of 28 proteins expressed in the seminal plasma of the azoospermia patients were statistically different from those of the healthy fertile males (P < 0.05 ), of which 24 were of lower contents than in the normal controls, 4 with remarkably significant difference, M/Z 7 196.058, 7 630.573, 7 547.610 and 7 709.833 (P < 0.01).

CONCLUSIONThe seminal plasma proteins of the azoospermia patients were significantly different from those of the healthy fertile males, with decreased contents of most of the different proteins, which might be significantly correlated with the development of azoospermia.

BACKGROUNDProteasome subunits (PSMB) and transporter associated with antigen processing (TAP) loci are located in the human leukocyte antigen (HLA) Class II region play important roles in immune response and protein degradation in neurodegenerative diseases. This study aimed to explore the association between single nucleotide polymorphisms (SNPs) of PSMB and TAP and Parkinson's disease (PD).

METHODSA case-control study was conducted by genotyping SNPs in PSMB8, PSMB9, TAP1, and TAP2 genes in the Chinese population. Subjects included 542 sporadic patients with PD and 674 healthy controls. Nine identified SNPs in PSMB8, PSMB9, TAP1, and TAP2 were genotyped through SNaPshot testing.

RESULTSThe stratified analysis of rs17587 was specially performed on gender. Data revealed that female patients carry a higher frequency of rs17587-G/G versus (A/A + G/A) compared with controls. But there was no significant difference with respect to the genotypic frequencies of the SNPs in PSMB8, TAP1, and TAP2 loci in PD patients.

CONCLUSIONChinese females carrying the rs17587-G/G genotype in PSMB9 may increase a higher risk for PD, but no linkage was found between other SNPs in HLA Class II region and PD.

The study was aimed to investigate the application value of interphase fluorescence in situ hybridization (FISH) on cell smears in hematological diseases. Both interphase FISH on peripheral blood smears and bone marrow smears treated by methanol/acetic acid, and routine interphase FISH of bone marrow cells dropped on slides were done at the same time, in order to detect Ph chromosome by BCR/ABL dual color, dual fusion probe in 20 patients with chronic myelogenous leukemia or acute lymphoblastic leukemia which had been proven to display Ph chromosome positive. The results indicated that as compared with routine interphase FISH, the interphase FISH on cell smears could also offer reliable result. It is concluded that interphase FISH on cell smears is a kind of reliable and time-saving technique, which is also suitable for retrospective research and worthy to further apply in clinic.

An adult man of methylmalonic acidemia combined with hyperhomocysteinemia is reported. He presented with progressive walking instability with mental and behavioral alterations when aged 24 years. Physical examination showed significant cerebellar ataxia and pyramidal signs. Brain magnetic resonance imaging revealed symmetric lesions of bilateral cerebellum. His plasma total homocysteine and urine methylmalonic acid were significantly elevated. Compound heterozygous mutations, c.482G>A and c.217C>T, were found in his MMACHC gene, confirming the diagnosis of cblC deficiency. Improved clinical manifestations and decreased plasma total homocysteine were observed one month after treatment.

Given that the current Newcastle disease virus (NDV) infection in wild birds poses the threat to poultry, surveillance of Newcastle disease in captive wild birds was carried out in Jilin, China in 2018. Here, an NDV strain obtained from toco toucan was firstly characterized.The results showed that the F gene of the NDV isolate Toucan/China/3/2018 is classified as genotype II in class II. Sequence analysis of the F0 cleavage site was 113 RQGR/L 117 , which supports the result of the intracerebral pathogenicity index assay indicating classification of the isolate as low-pathogenicity. Experimental infection demonstrated that Toucan/ China/3/2018 can effectively replicate and transmit among chickens. To our knowledge, this is the first report on genetically and pathogenically characterizing NDV strain isolated from toucan, which enriches the epidemiological information of NDV in wild birds.
