Objective To discuss the clinicopathologic characteristics and risk factors for lung metastasis of early-stage cervical cancer after radical hysterectomy. Methods The complete clinicopathologic data of patients with lung metastasis of cervical cancer after radical surgery from January 2008 to December 2013 admitted in Zhejiang Cancer Hospital were retrospectively analyzed by univariate and multivariate analysis. Results (1)There were 38 cases of early cervical cancer suffered from lung metastasis after radical hysterectomy during the period. The median age at diagnosis of cervical cancer was 46 years, the average lung metastasis time was 13 months after operation, 50.0%(19/38) cases occurred in the first year. Thirty-one cases were squamous cell carcinoma and 7 cases were non-squamous cell carcinoma.(2)Univariate analysis showed that age,clinical stage, manner of tumor growth, tumor grade, perineuronal invasion, para-aortic lymph node metastasis were not significant effect on postoperative lung metastasis(all P>0.05). But tumor size, histologic types, depth of stromal invasion, uterine body infiltration, lympho-vascular space invasion,pelvic lymph node metastasis, positive margin and abnormal tumor markers were significantly correlated with postoperative lung metastasis(all P<0.05). Multivariate analysis showed that only tumor size, histologic types and pelvic lymph node metastasis were independent risk factors for lung metastasis of cervical cancer(P<0.05). Conclusions Patients of early-stage cervical cancer with lung metastasis mostly occurs within 1 year after radical hysterectomy. Local large tumor lesions (tumor size>4 cm), non-squamous cell carcinoma and pelvic lymph node metastasis were more likely to have lung metastasis.

Objective The article was to speed up the dissolution rate of poorly soluble drugs, reduce the configuration time and improve the allocative efficiency by analysis on factors influencing dissolution and adoption of proper allocative approaches accord-ing to different characteristics of insaluble drugs. Methods 5 insaluable drugs were chosen for the study, which were ornithine as-partate, mezlocillin sodium and sulbactam sodium, teicoplanin, omeprazole sodium injection and imipenem and cilastatin sodium.The control group were allocated by routine configuration approach, while the experiment group were improved by increasing the amount of solvent, loosing the powder inside the bottle before configuration, reducing the bubble, adopting special solvent and increasing the dis-solution temperature.Observation and comparative experiment were made on two groups along with the timing from configuration to com-plete dissolution into clear transparent liquid. Results As to the average complete dissolution time of 5 drugs, significant difference was found between two groups([42±5]s vs [246±35]s, [3±1]min vs [30±3]min, [5±1]min vs [10±3]min, [5±3]min vs [10± 5]min, [2±1]min vs [10±1]min, P<0.05).Compared with the control group, the dissolution time of 5 drugs was cut down by 83%, 90%, 50%, 50%, 80%in experiment group. Conclusion Appropriate increase of solvent, loose powder, bubble reduction, special solvent and increased solution temperature contribute to shortening the dissolution time of insoluble drugs and improving the configura-tion efficiency of pharmacy intravenous admixture.

Objective To explore and analyze the prescription patterns of Professor Zhou Min in treating primary liver cancer at different stages according to the China Liver Cancer Staging (CNLC) system. Methods The clinical records of outpatients with primary liver cancer treated by Professor Zhou Min were collected and entered into the Traditional Chinese Medicine Inheritance Support System (Version 2.50) to establish a database. Data mining methods such as frequency analysis, drug association analysis, and cluster analysis were employed, the pathogenesis of primary liver cancer the prescription patterns at different stages was explored and medication rules were analyzed according to Professor Zhou Min's experience in treating liver cancer at various CNLC stages. Results A total of 202 prescriptions from 113 patients with primary liver cancer were collected, involving 230 traditional Chinese medicines. The high-frequency drugs and drug combinations at each stage were identified. The drugs with higher frequencies at each stage included Fuling, Chenpi, Yiyiren, fried Baishu, and Fabanxia. For stage Ⅰ, high-frequency drugs also included Zhongjiefeng, Xiangfu, Jiangcan, and Jianghuang. For stages Ⅱ and Ⅲ, high-frequency drugs further encompassed Zhongjiefeng, Xianhecao, Banzhilian, Baihua Sheshecao, Jiangcan, Zeqi, Xiangfu, and Maidong. For stage Ⅳ, high-frequency drugs also include Maydis stigma, Huoxiang, fried Maiya, Jineijin, and fried Guya. The majority of the drugs were cold in nature, with sweet and bitter tastes being the most common, and their meridian tropism were mostly distributed in the spleen and stomach meridians. The drug combinations with higher frequencies at each stage were mostly derived from Sijunzi Decoction and Erchen Decoction. The drug efficacies were mainly heat-clearing and dampness-resolving. Cluster analysis screened out new prescriptions with unique characteristics at each stage. Conclusion By performing data mining on the prescriptions used by Professor Zhou Min in treating primary liver cancer at various CNLC stages through the Traditional Chinese Medicine Inheritance Platform, combined with his understanding of the pathogenesis and clinical experience of the disease, the pathogenesis characteristics of primary liver cancer are summarized as dampness-heat, phlegm, and toxin accumulation, as well as qi and yin deficiency. The basic treatment methods established are heat-clearing and dampness-resolving, spleen-invigorating and yin-nourishing, with an emphasis on strengthening the body resistance to eliminate pathogenic factors and stage-based treatment. Flexible prescriptions and medications are used for different complications.

The study aims to identify the role of cAMP-PKA pathway in the group Ⅱ metabotropic glutamate receptors (mGluRs)-mediated regulation of respiratory rhythm from the brainstem slice. Neonatal (aged 0-3 d) Sprague-Dawley rats of either sex were used. The brainstem slice containing the medial region of the nucleus retrofacialis (mNRF) and the hypoglossal nerve rootlets was prepared, and the surgical procedure was performed in the modified Kreb's solution (MKS) with continuous carbogen (95% O2 and 5% CO2) bubbling, and ended in 3 min. Respiratory rhythmical discharge activity (RRDA) of the hypoglossal nerve rootlets was recorded by suction electrode. Eighteen brainstem slice preparations were divided into 3 groups. In group 1, group Ⅱ mGluRs specific antagonist (2S)-α-ethylglutamic acid (EGLU) was added into the perfusion solution for 10 min. In group 2, after application of Forskolin for 10 min, washout with MKS, the slice was perfused with Rp-cyclic 3', 5'-hydrogen phosphorothioate adenosine triethylammonium salt (Rp-cAMPS) alone for another 10 min. In group 3, after application of Rp-cAMPS for 10 min, additional EGLU was added into the perfusion for another 10 min. The results showed EGLU shortened respiratory cycle (RC), but the changes of integral amplitude (IA) and inspiratory time (TI) were not statistically significant. Forskolin induced significant decreases in RC, and increased TI, IA. Rp-cAMPS could make the opposite effect compared with the changes of RRDA with Forskolin. The effect of EGLU on the RRDA was inhibited after blocking the cAMP-PKA pathway. Taken together, cAMP-PKA pathway may play an important role in the group Ⅱ mGluRs-mediated regulation of RRDA in the brainstem slice of neonatal rats.

Abstract: Objective　To understand the distribution and drug resistance of bacteria in clinical blood culture specimens in Ningxia in recent years, and to provide a basis for the prevention and treatment of bloodstream infection diseases. 　　　Methods　The blood culture isolation bacteria and drug resistance of Ningxia bacterial resistance monitoring network hospitals from 2018 to 2020 were statistically analyzed by WHONET5.6 software. Results　In the past three years, a total of 6 757 strains of bacteria were isolated from blood samples, including 3 697 strains (54.7%) of gram-negative bacteria and 3 060 (45.3%) of gram-positive bacteria. Among the gram-negative bacteria, Escherichia coli (2 074 strains,30.7%), Klebsiella pneumoniae (696 strains), Pseudomonas aeruginosa (139 strains), and Acinetobacter baumannii (121 strains). Among the gram-positive bacteria, coagulase-negative Staphylococcus (1 691 strains,25.0%), Staphylococcus aureus (442 strains), Streptococcus spp. (431 strains), Enterococcus spp. (379 strains). Resistance to Escherichia coli and Klebsiella pneumoniae was 56.6% and 22.6% against third-generation cephalosporins, and resistance to carbapenems was 1.0% and 3.7%, respectively. Pseudomonas aeruginosa and Acinetobacter baumannii were resistant to carbapenems at 9.0%（12/139） and 80.7%（71/121）. Methicillin-resistant Staphylococcus aureus (MRSA) was detected at 26.8%, methicillin-resistant coagulase-negative Staphylococcus was detected at 70%, and no Staphylococcus bacteria resistant to vancomycin and linezolid were found. For three years, only 1 strain of vancomycin-resistant Enterococcus faecalis was detected, and no linezolid-resistant Staphylococcus and Enterococcus were detected. Conclusions　Ningxia clinical blood specimen isolates of Escherichia coli, coagulase-negative Staphylococcus, and Klebsiella pneumoniae are more common. Among them, the resistance rate of Escherichia coli and Klebsiella pneumoniae to the third generation of cephalosporins is relatively stable, and the resistance rate to carbapenems is low. Acinetobacter baumannii is highly resistant to carbapenems, and methicillin-resistant Staphylococcus aureus detection rates are on the rise and should be closely monitored.
