Herbal Textual Research on Coptidis Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

Through the combing of ancient books of Chinese herbal medicine in the past dynasties， a textual research of Coptidis Rhizoma involved the name， origin， medicinal parts， producing area， quality evaluation， harvesting and processing methods in famous classical formulas was conducted in this paper. After textual research， the mainstream varieties of Coptidis Rhizoma in the Ranunculaceae family before Tang and Song dynasties were Coptis chinensis and C. chinensis var. brevisepala， after the Ming and Qing dynasties， C. deltoidea， C. teeta and C. omeiensis were gradually praised. In ancient times， the authentic producing area of Coptidis Rhizoma has the characteristics of gradually moving to the west. The eastern Coptidis Rhizoma was highly praised in the early stage， while in the later stage， western Coptidis Rhizoma like chicken feet was highly praised. In the early stage， western Coptidis Rhizoma probably originated from C. chinensis and its genus， while Coptidis Rhizoma like chicken feet was cultivated， and no wild species has been found so far. As Coptidis Rhizoma has mixed use of multiple origins in ancient books of past dynasties， based on the current shortage of market resources in C. teeta and C. deltoidea， there are also endangered and protected plants of C. chinensis var. brevisepala and C. omeiensis， combined with the mainstream medicines and resources of past generations， it is recommended to choose C. chinensis as the base of the formulas. In ancient times， there were many processing methods for Coptidis Rhizoma， such as frying and wine-， ginger-， honey-processed. In the process of developing famous classical formulas， the appropriate processing specifications of Coptidis Rhizoma should be selected based on the original source records and the requirements of the medicinal material.

Development and validation of a deep learning model to screen hypokalemia from electrocardiogram in emergency patients / 中华医学杂志(英文版)

BACKGROUND@#A deep learning model (DLM) that enables non-invasive hypokalemia screening from an electrocardiogram (ECG) may improve the detection of this life-threatening condition. This study aimed to develop and evaluate the performance of a DLM for the detection of hypokalemia from the ECGs of emergency patients.@*METHODS@#We used a total of 9908 ECG data from emergency patients who were admitted at the Second Affiliated Hospital of Nanchang University, Jiangxi, China, from September 2017 to October 2020. The DLM was trained using 12 ECG leads (lead I, II, III, aVR, aVL, aVF, and V1-6) to detect patients with serum potassium concentrations <3.5 mmol/L and was validated using retrospective data from the Jiangling branch of the Second Affiliated Hospital of Nanchang University. The blood draw was completed within 10 min before and after the ECG examination, and there was no new or ongoing infusion during this period.@*RESULTS@#We used 6904 ECGs and 1726 ECGs as development and internal validation data sets, respectively. In addition, 1278 ECGs from the Jiangling branch of the Second Affiliated Hospital of Nanchang University were used as external validation data sets. Using 12 ECG leads (leads I, II, III, aVR, aVL, aVF, and V1-6), the area under the receiver operating characteristic curve (AUC) of the DLM was 0.80 (95% confidence interval [CI]: 0.77-0.82) for the internal validation data set. Using an optimal operating point yielded a sensitivity of 71.4% and a specificity of 77.1%. Using the same 12 ECG leads, the external validation data set resulted in an AUC for the DLM of 0.77 (95% CI: 0.75-0.79). Using an optimal operating point yielded a sensitivity of 70.0% and a specificity of 69.1%.@*CONCLUSIONS@#In this study, using 12 ECG leads, a DLM detected hypokalemia in emergency patients with an AUC of 0.77 to 0.80. Artificial intelligence could be used to analyze an ECG to quickly screen for hypokalemia.

@#AIM: To verify the accuracy of Van Herick method and slit-lamp anterior chamber depth examination in estimating angle closure. <p>METHODS: Totally 52 patients(100 eyes)over 40 years old were randomly selected from our outpatient department from June 2018 to January 2019.Their anterior chamber depth were examined by the methods of Van Herick method and the improved method to sort out peripheral anterior chamber depth are less than or equal to 1/3 CT and more than 1/4 CT and peripheral anterior chamber depth are less than or equal to 1/4 CT. Van Herick's anterior chamber depth inspection method and improved anterior chamber depth inspection method were checked for consistency, and then gonioscopic inspection and UBM inspection under darkroom were performed to check whether the peripheral angle was closed. In order to know whether there was any difference between gonioscopic and UBM inspection for angle closure, the consistency of the two verification results was checked. <p>RESULTS: Peripheral anterior chamber depth are less than or equal to 1/3 CT and more than 1/4 CT by the methods of Van Herick, the positive incidence of angle closure in angioscopy and ultrasound biomicroscopy are 39% and 43% respectively, Peripheral anterior chamber depth are less than or equal to 1/3 CT and more than 1/4 CT by the improved methods, the positive incidence of angle closure in angioscopy and ultrasound biomicroscopyare 46% and 42% respectively. In the patients whose peripheral anterior chamber depth checked by angioscopy and ultrasound biomicroscopy is less than or equal to 1/4 CT estimated by Van Herick method, the positive rate of angle closure was 67% and 89%, respectively. In the patients whose peripheral anterior chamber depth checked by angioscopy and ultrasound biomicroscopy is less than or equal to 1/4 CT estimated by the improved method, the positive rate of angle closure was 67% and 89%, respectively. The consistency test of the Van Herick method and the improved method showed good consistency(Kappa value: 0.85), when peripheral anterior chamber depth are less than or equal to 1/3 CT and more than 1/4 CT. peripheral anterior chamber depth(>1/4 CT), and good consistency(Kappa value: 0.83)when estimating peripheral anterior chamber depth ≤1/4 CT. According to the consistency test of the results of angioscopy and ultrasound biomicroscopy, when the Van Herick method estimated the depth of peripheral anterior chamber are less than or equal to 1/3 CT and more than 1/4 CT, the consistency was general(Kappa value: 0.73). When the Van Herick method estimated the depth of peripheral anterior chamber is less than or equal to 1/4 CT, the consistency was general(Kappa value: 0.40). According to the consistency test of the results of angioscopy and ultrasound biomicroscopy, when the improved method estimated the depth of peripheral anterior chamber are less than or equal to 1/3 CT and more than 1/4 CT, the consistency was good(Kappa value: 0.75). When the improved method estimated the depth of peripheral anterior chamber is less than or equal to 1/4 CT, the consistency was poor(Kappa value: 0). <p>CONCLUSION: The slit lamp anterior chamber depth examination has a certain false negative rate in estimating the angle closure in the population, but its accuracy is high, and it is still suitable for the preliminary examination of estimating the angle closure.

Establishment of a screening model for compounds uncoupling the interaction of nNOS with PSD-95 / 药学学报

In ischemic stroke, increased level of neuronal complex of nitric oxide synthase (nNOS)-postsynaptic density protein-95 (PSD-95) plays an important role in neuronal damage. We aimed to establish a screening model to identify compounds capable of uncoupling nNOS interaction with PSD-95. In this model, human embryonic kidney-293T (HEK-293T) cells were transfected with either pCDH-Flag-nNOS or pcDNA3.1-PSD-95 plasmid to obtain the protein of Flag-nNOS or PSD-95. Incubating Flag-nNOS with PSD-95 causes formation of the nNOS-PSD-95 complex. ZL006, a known uncoupler of nNOS-PSD-95 interaction, can disturb the interaction between Flag-nNOS and PSD-95, serving as a positive control. The method coupling antibodies to magnetic beads with glutaraldehyde was used to decrease the cost and increase the efficiency. To establish that our model is suitable for selecting nNOS-PSD-95 uncouplers, we evaluated the ability of IC87201, another reported uncoupler of nNOS-PSD-95 interaction, and structural analogs of ZL006. IC87201 and one structure analog of ZL006 showed uncoupling effect, supporting that our model can be used to select different types uncoupler blocking nNOS-PSD-95 interaction.

Lesch-Nyhan syndrome in a Chinese family with mutation in the HGPRT gene / 中国生化药物杂志

Lesch-Nyhan syndrome(LNS) is a congenital X-linked recessive inherited disorder caused by mutations in the hypoxanthine guanine phosphoribosyl transferase (HPRT) gene.A deficiency of the HPRT enzyme is responsible for the disease.The main clinical manifestation includes hyperuricemia, juvenile-onset gouty arthritis and neurological developmental disorders.Studies have reported there are more than 400 HPRT gene mutation sites, but the incidence of LNS in the Chinese population is extremely low.Here we report a 16-year-old male patient who suffered neurological dysfunction at an early age and gouty arthritis in his youth.DNA of patient and his family members were extracted from peripheral blood lymphocytes.The coding region and the intron-exon boundaries of HPRT gene were sequenced by standard methods.We found a mutation in exon 3 of the HPRT gene of the patient and his mother (Exon3:c.143G>A), which resulted in an arginine to histidine (p.R48H) substitution in the encoded protein.No activity of the enzyme HPRT was detected in the erythrocytes.The same mutation was reported in several European families, but was found in Chinese family for the first time.Clinicians in China have poor experience in diagnosing LNS case, due to the low incidence in China.Therefore LNS screening for infants or adolescents with hyperuricemia, gouty arthritis and neurological dysfunction should be performed.
