OBJECTIVETo observe the curative effect of integrative medicine for treatment of systematic lupu erythematosus (SLE).

METHODSTotally 110 cases of SLE were randomized into two groups, 50 in the control group and 60 in the treated group, both were treated with prednisone, but to the treated group, integrative medica treatment was given additionally according to syndrome differentiation. The course for both groups was 6 months. Clinical symptoms, immunological indexes, peripheral blood figure, erythrocyte sedimentation rate (ESR), levels of C-reactive protein (CRP) and creatinine (Cr) in blood, and 24 h urinary total protein (u-TP/24 h) were observed before and after treatment.

RESULTSOf the 60 patients in the treated group, the treatment on 29 was evaluated as clinical remission, 18 as remarkably effective, 9 as effective, and 4 as ineffective, the total effective rate being 93.33% (56/60), while that in the control group was clinical remission in 11, remarkably effective in 10, effective in 19, ineffective in 10 respectively, and the total effective rate 80% (40/50), the difference on total ef fective rate between the two groups was significant (chi2 = 4.36, P <0.05). Besides, the improvement in the treated group was superior to that in the control group in terms of clinical symptoms such as fever, arthralgia and baldness (P <0.05, P <0.01); the negative reversion rate of anti-nuclear antibody (ANA, 51.3% vs 28.1%), antidouble-stranded DNA (ds-DNA, 53.6% vs 26.1%), anti- ribonucleoprotein (RNP, 63.2% vs 29.4%) and circulating immnue complexes (CIC, 63.2% vs 29.4%, all P <0.05); lowering of immunoglobulin (for IgG, P < 0.05; IgA, P <0.01; IgM, P <0.01); as well as bettering in peripheral blood figure, ESR, CRP, Cr and u-TP/24 h (P <0.05 or P <0.01).

CONCLUSIONIntegrative medical treatment is obviously effective for SLE patients.

Objective To investigate the epidemiological characteristics of foodborne diseases in Liuzhou City, and to provide reference for formulating the prevention and control measures of foodborne diseases. Methods The surveillance data of foodborne diseases in 25 sentinel hospitals in Liuzhou City from 2018 to 2020 were collected for statistical analysis. Results From 2018 to 2020, a total of 9 317 cases of foodborne diseases were reported in Liuzhou City, and 2 158 samples were collected for pathogen detection. A total of 311 cases were detected positive , with a detection rate of 14.41%. Norovirus had the highest detection rate (8.63%), followed by Salmonella (4.08%) and Escherichia coli (3.10%). July to October was a period of high incidence of foodborne disease（ 41.17%）. The proportion of patients aged 60 and over was the highest (18.49%), followed by the age group of 30-39 (18.03%). Suspicious foods were mainly meat and meat products (22.35%) and aquatic animals and their products (13.89%). The suspicious eating places were mainly families (40.43%) and restaurants (13.63%). Conclusion The high incidence of foodborne diseases in Liuzhou occurs in summer and autumn. The main pathogens are Salmonella and norovirus. Infected patients are concentrated in the age group of 60 years and above and the age group of 30 to 39 years old. The family is the main place of foodborne disease, followed by the restaurants and hotels. Suspicious foods include mainly meat and meat products and aquatic animals and their products. It is necessary to strengthen monitoring ability and food safety education to reduce the occurrence of foodborne diseases.

So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

Objective To evaluate the diagnosis and surgical treatment of parathyroid carcinoma (PTC). Methods Clinical data of 8 PTC cases were analyzed retrospectively. Results PTC accounted for 5. 7% of patients with primary hyperparathyroidism (PHPT) in our hospital. There were 4 men and 4 women. Male patients had younger mean onset age compared with female patients. The disease history of PTC was shorter than PHPT of benign causes. Six patients were admitted for acute hypercalcemia. Seven patients complained of palpable neck mass. Calcium level was 3.75?0.34 mmol/L,and PTH level was 1429.47?841.75 pg/ml. Frozen section established diagnosis in only one case. Four patients underwent radical en bloc resection. Other 4 cases received routine simple parathyroidectomy, 3 patients developed recurrence in 12 - 18 months postoperatively. Conclusions Acute hypercalcemia is common in PTC. Frozen biopsy diagnosis is not satisfactory. An initial en bloc resection of tumor and adjacent structures contributes most to the prognosis.

Objective To develop a method for content determination of sinensetin,eupatorin,and 3′-hydroxy-5,6,7, 4′-tetramethoxyflavone in Orthosiphon stamineus. Methods The determination was carried out on a Symmetry C18 column (4.6 mm×250 mm,5 μm) by HPLC.The mobile consisted of acetonitrile and water containing 0.05% H3 PO4 in gradient elution. The flow rate was 1 mL?min-1 ,the column temperature was 30 ℃ ,the detected wavelength was set at 365 nm, and the injection volume was 10 μL. Results The peak areas and the sample quantity of the three components presented good linear relationship in the range of 0. 50 - 5. 00 μg for sinensetin,0. 50 - 5. 00 μg for eupatorin, and 0. 05 - 0. 50 μg for 3′-hydroxy-5,6,7,4′-tetramethoxyflavone.The average recoveries were 101.26%,100.28% and 99.66%,respectively. RSD were 1.73%, 0.82% and 1.67%, respectively. Conclusion The method is proved to be simple,accurate and can be used for the quality evaluation of Orthosiphon stamineus.

Objective To analyze the CT features of renal cell carcinoma,so as to improve the diagnostic accuracy of renal cell carcinoma.Methods Three hundred cases of renal cell carcinoma proved by pathology were examined by means of CT.There were 214 male and 86 female in this group.Their age ranged from 9 to 81 years,with a mean of 53.7 years.Their CT features were retrospectively reviewed. Results The masses were 1.5—16.0 cm(mean,4.8 cm)in greatest dimension,125 masses on left kidney and 175 masses on right kidney.According to WHO histological classification of tumours of the kidney in 2004,there were 238 cases of clear cell renal cell carcinoma,6 cases of multilocular clear cell renal cell carcinomas,23 cases of papillary renal cell carcinoma,14 cases of chromophobe renal cell carcinoma and 19 cases of renal cell carcinoma,unclassified.The above subtype of renal cell carcinoma demonstrated characteristic features.Clear cell renal cell carcinoma exhibited inhomogenous(due to hemorrhage,necrosis or cystic degeneration)and hypervaseular.Multilocular clear cell renal cell carcinoma presented as a multilocular cystic mass lacking an,expansile nodule,and with regular thin cyst wall and septa.Papillary renal cell carcinoma exhibited inhomogenous and hypovascular.Chromophobe renal cell carcinoma was relatively homogenous and hypovascular.Renal cell carcinoma,unclassified showed inhomogenous and hypervascular,and was more invading growth compared to clear cell renal cell carcinoma. Conclusion Common subtype of renal cell carcinoma demonstrated characteristic features in CT and it is helpful for differentiation.

To construct a secretory-expression vector of antimicrobial peptide Bactenecin 7(Bac7),and identify the secretory-expression product in L.lactis MG1363 and its bioactivity.The splicing primers of regulation elements and Bac7 gene,which designed according to codon usage preferences of L.lactis MG1363,were chemically synthesized,and the overlap-extension PCR method was used to splice the full length of Bac7 gene.Then the Bac7 gene was linked to expression vector pMG36e to construct pMG36e/Bac7 vector,and pMG36e/Bac7 was transformed into L.lactis MG1363 by electrophoration.RT-PCR and Western blot assays were applied to investigate the expression of the Bac7 gene in L.lactis,and bioactivity of Bac7 in culture supernatant of L.lactis was tested with plate-diffusion method.The results showed that the Bac7 gene and its regulation elements was amplified and cloned in the vector pMG36e successfully,The secretory-expressed Bac7 in L.lactis MG1363 harboring pMG36e/Bac7 was identified by Western blot,and it had high bacteriostatic activity against E.coli.These results indicate that the recombinant L.lactis MG1363 could express bioactive Bac7,which lays a foundation for further study of oral administration of a Bac7-secreting L.lactis to treat intestinal bacteria infection.

To decrease the oxygen content in the cell is a key method to improve hydrogen production in Chlamydomonas reinhardtii.A new approach was developed by transforming the leghemoglobin gene lba,which has high affinity to oxygen,into the chloroplast of C.reinhardtii to get a low dissolved oxygen in the cell and result into improvement of H2 ase activity and H2 yield. The results showed that lba was successfully transformed into the chloroplast of C.reinahrdtii strain 849 and did not affect its growth significantly. The work paved the road for further regulation of lba expression in the chloroplast to improve of hydrogen production of C.reinahrdtii.

In order to provide a scientific basis for the establishment of a Daphnes Cortex medicinal material fungus library and the screening of endophytic fungi that promote the growth of Daphnes Cortex and increase the content of daphnetin, we used Illumina high-throughput testing technology to analyze 9 Daphnes Cortex samples from Gansu and Shanxi provinces. A total of 632 766 valid sequences were obtained, including 348 OTUs, 4 phyla, 20 classes, 48 orders, 108 families, 154 genera, and 208 species. The sum of the first 3 fungal genera account for more than 65% of the total abundance, with the highest reaching 98.4%. Alternaria and Phoma are the main genuses of Daphne giraldii Nitsche, and Altemaria is the dominant genus. The endophytic fungi community of Daphnes Cortex is rich in diversity, and the order of fungal diversity in different producing areas is: Gangu County > Wutai County > Tanchang County.
