ABSTRACT
Objective:To investigate the accuracy, effectiveness and feasibility of MassARRAY genotyping assay in the diagnoses of neonatal genetic metabolic diseases.Methods:This is a retrospective study. From December 2016 to January 2020, newborns were screened by tandem mass spectrometry at the Zhejiang Newborn Screening Center, among which the data of 7 922 suspected positive cases of genetic metabolic diseases were collected. These patients were then tested for the common variants of 27 genetic metabolic diseases by MassARRAY genotyping assay, along with further testing using Sanger or next-generation sequencing used to verify and/or further search for potential variants.Results:A total of 1 408 cases were tested with MassARRAY. Among these, 307 cases were confirmed with certain genetic metabolic diseases. The detection rate of hyperphenylalaninemia was the highest, followed by primary carnitine deficiency, short acyl-coA dehydrogenase deficiency and methylmalonic acidemia. With these cases, the consistency of Sanger sequencing and MassARRAY was 100% (307/307). Another 287 cases were identified as carriers by MassARRAY with a 49.1% (141/287) consistency in reference to Sanger sequencing, mainly involving SLC22A5 and MCCC1 genes. Meanwhile, 50.8% (146/287) of these cases were found to have another variant mainly involving PAH, PTS and ACADS genes. The remaining 814 cases have no variants; 158 cases out of these patients have continuously abnormal amino acids, acyl carnitines, urine organic acid and/or other biochemical indices, and were tested by next-generation sequencing, among which 38% (60/158) were detected with two variants. In this study, a total of 513 patients with genetic metabolic disease were diagnosed, and the detection rate of MassARRAY was 59.8% (307/513). Conclusions:MassARRAY genotyping assay can be used as an early molecular screening method for neonatal genetic metabolic diseases. The detection rate is particularly high in diseases with a high concentration of hotspot variants, such as hyperphenylalaninemia and primary carnitine deficiency. The future application value of MassARRAY should be further improved by continuously optimizing its ability to identify new disease genes and potential variable sites.

ABSTRACT
Quality evaluation based on character identification of traditional Chinese medicinal materials is the wisdom crystallization of the long-term medication experience of the pharmacists in the past dynasties， and is a quality evaluation system with the characteristics of traditional Chinese medicine （TCM）. Because of its simple language， easy to understand and easy to operate， it plays an important guiding role in the quality evaluation of TCM. Modern electronic sensory apparatus technology can realize the objective expression of TCM characters. Some scholars correlated their expression results with the contents of the main chemical components in TCM， proving that quality evaluation based on character identification of traditional Chinese medicinal materials has a certain scientific basis. However， the scientific connotation of quality evaluation based on character identification of traditional Chinese medicinal materials has not yet been clearly clarified. There is a lack of systematic research on which characters of TCM can truly reflect its quality. Therefore， the author summarizes quality evaluation based on character identification of traditional Chinese medicinal materials from three aspects. It makes clear that the idea of quality evaluation based on character identification of traditional Chinese medicinal materials is derived from analogical thinking， and combs the four stages of germination， development， prosperity and maturity experienced in its formation process， summarizes the modern research progress of this theory， clarifies that the role of the theory in evaluating the quality of medicinal materials， guiding the classification of commodity specifications， and harvesting and processing of medicinal materials. It is recommended that the follow-up should be strengthened on the research of quality evaluation based on character identification of traditional Chinese medicinal materials， make full use of electronic sensory instruments， liquid-mass spectrometry， biological efficacy evaluation and other technologies， strengthen the objective description of the characteristics of TCM， and attach importance to the analysis of the correlation between the overall characteristics of TCM and its efficacy， and establish a new research model related to the characteristics-active ingredients-pharmaceutical effects of TCM， in order to elucidate the scientific connotation of quality evaluation based on character identification of traditional Chinese medicinal materials， so as to better serve the quality evaluation of TCM.
ABSTRACT
OBJECTIVE: To evaluate the application value of finger systolic blood pressure(FSBP) in the diagnosis of vibration-induced vascular injury. METHODS: Thirty patients with vibration-induced vascular injury [vibration-induced white finger(VWF)] were selected as the case group by a non-randomized concurrent controlled trial, and 30 hand-transmitted vibration workers without VWF were selected as the control group. The FSBP test was performed on the tested hands of all subjects, and the FSBP index of each Finger(F_( i)) was measured. RESULTS: The F_i of the index finger, middle finger, ring finger and tail finger of the tested hand in the case group were lower than that in the control group(all P<0.01). In the case group, the F_i of index finger was lower than ring finger and tail finger(all P<0.01). The abnormal rates of F_i on the index, middle and ring fingers in the case group were higher than those in the control group(86.7% vs 10.0%, 76.7% vs 13.3%, 43.3% vs 10.0%, all P<0.01). The area under the receiver operator characteristic curve of the measured F_i of the index finger, middle finger, ring finger and tail finger were 0.884, 0.843, 0.764 and 0.687 respectively. The diagnostic cut off value of the F_i of index finger was 80.2%. The sensitivity and specificity were 86.7% and 90.0%, respectively. CONCLUSION: FSBP test has a good application value in the diagnosis of vibration-induced vascular injuries. It is suggested that the F_i of index finger be the first choice as the diagnostic index, and the abnormal value can be set at 80.0%.
ABSTRACT
SUMMARY OBJECTIVE This study aims to investigate the application value of magnetic resonance (MR) hydrography of the inner ear in cochlear implantation. METHODS 146 patients were enrolled. MR hydrography and spiral CT examinations for the intracranial auditory canal were performed before surgery, and all imaging results were statistically analyzed in order to explore the application value of MR hydrography of the inner ear in cochlear implantation. RESULTS 146 patients (292 ears) were examined. Among these patients, 13 were diagnosed with abnormal vestibular aqueducts (20 ears) by MR hydrography, while five were diagnosed with this disease by CT; 15 patients were diagnosed with inner ear malformation (19 ears) by MR hydrography, while 11 were diagnosed by CT (four were misdiagnosed); five patients were diagnosed with internal acoustic canal stenosis (eight ears) by MR hydrography, while two were diagnosed by CT (three were misdiagnosed); and four patients were diagnosed with cochlear fibrosis (five ears) by MR hydrography, while four were diagnosed by CT (four ears). The correct rate of diagnosis was 77.40% (113/146) based on CT, while the rate was 93.84% (137/146) based on MR hydrography. CONCLUSIONS MR hydrography imaging technique can be applied to the preoperative evaluation of cochlear implantation, providing accurate and reliable anatomic information on the inner membranous labyrinth and nerves in the internal acoustic canal and an accurate basis for the diagnosis of cochlear fibrosis and nerve development. This has a guiding significance for the selection of treatment schemes.

To introduce the application status of network Meta-analysis( NMA) in the field of traditional Chinese medicine,and to discuss the application value of NMA in the field of traditional Chinese medicine,this study comprehensively reviewed the systematic reviews with application of NMA in the field of traditional Chinese medicine. CNKI,Wan Fang,Sino Med,VIP,Embase,PubMed and Cochrane Library and the reference list of previous studies were searched. The AMSTAR scale was used to evaluate the quality of literature methodology,and PRISMA-NMA checklist was used to measure the degree of report specification. Overall,122 articles were included,including 80 in Chinese and 42 in English. The included studies centered on cancer,bone and joint disease,cardiovascular disease,respiratory disease,mental disease and digestive disease. Additionally,the intervention can be categorized into three groups,traditional Chinese medicine injection,oral Chinese medicine or prescription,and traditional physical therapy including acupuncture.Nearly one-third of the researches' intervention program is aimed at comparing the effect of Chinese and Western combined therapy and monotherapy. The overall methodology quality grade is medium and the report quality is average,with methodology reporting and result reporting especially need to be improved. The subgroup analysis shows that the methodology quality of the English literatures is evidently higher than Chinese literatures,and the quality of the literatures published after 2015 is higher than those published in or before 2015.This study indicates that the NMA can compare multiple treatments simultaneously,which accords with characteristics of the clinical practice in traditional Chinese medicine that is complex and individual. NMA in the field of traditional Chinese medicine is still in the process of development. With higher level of quality control and reporting as well as the improvement of the statistical methodology and the accumulation of original researches,NMA application in the field of traditional Chinese medicine will be promising.

ABSTRACT
Objective To investigate the changes in serum procalcitonin (PCT) in patients with severe pneumonia, and to analyze its value on evaluating the clinical outcome of patients with severe pneumonia. Methods A total of 58 patients with severe pneumonia aged over 18 years, and admitted to intensive care unit (ICU) of Zhuozhou City Hospital of Hebei Province from January 2017 to July 2018 were enrolled. The patients were divided into recovery group (the symptoms and signs of pneumonia disappeared or improved, and the X-ray chest films improved or did not make significant progress) and deterioration group (the symptoms and signs of pneumonia persisted or progressed, while X-ray chest radiography progressed, as well as serious complications such as involvement of other organ functions due to deterioration of pulmonary infection or septic shock) according to the therapeutic outcome. The serum PCT levels at 1, 3, 5, 7, 9 days after severe pneumonia diagnosed were recorded, and procalcitonin clearance rate (PCTc) was calculated. The acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score was estimated within 24 hours when severe pneumonia was diagnosed. Receiver operating characteristic (ROC) curve was drawn, and the area under ROC curve (AUC) was calculated to analyze the value of PCTc on evaluating the clinical outcome of patients with severe pneumonia. Results Among 58 patients, 33 (56.9%) had better outcome after active treatment (recovery group), and 25 (44.1%) had worse condition (deterioration group). There was no significant difference in PCT level at 1 day or 3 days between the recovery group and the deterioration group [μg/L: 5.05 (3.89, 7.61) vs. 5.29 (4.15, 7.46) at 1 day, 4.59 (4.02, 6.90) vs. 5.70 (4.59, 7.28) at 3 days, both P > 0.05]. With the prolongation of treatment time, serum PCT level was gradually decreased in the recovery group, while remained at higher level in the deterioration group, which was significantly lowered at 5, 7, 9 days in the recovery group as compared with that in the deterioration group [μg/L:2.92 (2.09, 3.42) vs. 6.09 (3.24, 7.96) at 5 days, 1.94 (1.50, 2.07) vs. 7.65 (5.60, 10.52) at 7 days, 1.37 (0.91, 1.74) vs. 8.96 (6.09, 10.87) at 9 days, all P < 0.01]. PCTc at 3, 5, 7, 9 days in the recovery group were significantly higher than those in the deterioration group [15.10 (-17.80, 32.10)% vs. -1.53 (-20.80, 11.48)% at 3 days, 47.50 (30.25, 60.34)% vs. 6.25 (-14.58, 29.05)% at 5 days, 76.44 (53.18, 77.92)% vs. -11.20 (-66.75, -1.38)% at 7 days, 80.01 (59.86, 88.27)% vs. -38.15 (-99.38, -2.81)% at 9 days, all P < 0.05]. ROC curve analysis showed that PCTc at 3, 5, 7 and 9 days were valuable for evaluating the clinical outcome of patients with severe pneumonia, and 9-day PCTc had the greatest value, the AUC was 0.978 [95% confidence interval (95%CI) = 0.945-1.000, P = 0.000], which was higher than APACHEⅡ(AUC = 0.442, 95%CI = 0.280-0.610, P = 0.392); when the best cut-off value of 9-day PCTc was 93.00%, its sensitivity was 99.0%, and specificity was 87.3%. Conclusions The PCT level of patients with severe pneumonia remained at a high level, which was related with the deterioration of the disease. PCTc, as an index to evaluate the clinical outcome of patients with severe pneumonia, has good application value.

The difference was statistically significant (χ2=13.611, P<0.05).@*Conclusions@#Prophylactic care can be used in the mechanical ventilation of premature infants with NRDS, which can significantly reduce the incidence of complications, reduce the amount of pulmonary surfactant, shorten the mechanical ventilation time, and save the cost of treatment. It is worth promoting.
ABSTRACT
Objective To evaluate the value of a dynamic automatic identification system in routine miracidium hatching test with nylon gauzes. Methods Different quantities of fresh Schistosoma japonicum eggs were added to bovine fecal samples and divided into the low-infection group, medium-infection group and high-infection group, while the bovine feces without S. japonicum eggs served as negative controls. The detection efficiency and accuracy were compared between the identification system and manual detection in different groups. Results The identification system can automatically identify S. japonicum miracidium. The detection rate and efficiency of S. japonicum miracidium in bovine fecal samples were both higher by using the identification system than by manual detection. Notably in the low-infection group, the identification system had a significantly higher rate of detection of S. japonicum miracidium than manual detection (χ2 = 10.769, P = 0.002). The identification system completed the detection of bovine fecal samples in the field within 1 min. Conclusions The dynamic automatic identification system may effectively improve the detection efficiency and accuracy of routine miracidium hatching test with nylon gauzes, and it may replace manual detection to be used in the field schisotsomiasis examinations and related researches.

ABSTRACT
@#AIM:To observe and analyze the effect of non-mydriatic fundus photography in screening diabetic retinopathy(DR), so as to provide the basis for clinical screening.<p>METHODS:In our hospital from December 2016 to November 2017, 120 patients(240 eyes)was diagnosed as diabetes(DM), which were treated as the subjects of observation. By the same operator with non-mydriatic fundus photography, fundus photography and 7 range fundus fluorescein angiography(FFA)after mydriasis were taken. Taking the international clinical classification of diabetic retinopathy(DR)as the standard, the above three examinations were review, grade and record by the same physician by blind method. The fundus fluorescein angiography as the gold standard, the other two results were compared to detect the sensitivity, specificity, Youden index, Kappa value of the two for DR with different grade.<p>RESULTS: There was 70.0% eyes diagnosed as diabetic retinopathy after screened by fundus angiography, 66.7% by post-mydriatic fundus photography, 65.0% by non-mydriatic fundus photography. The grading results of diabetic retinopathy screened by different methods were basically consistent, with no significant difference(<i>P</i>>0.05). When screening for diabetic retinopathy of different degrees, the sensitivity and specificity of the non-mydriatic group were 92.9% and 90.3%, respectively. There was no significant difference between the results of the non-mydriatic group and the non-mydriatic group. Compared with the gold standard group(FFA), the Youden index(83.14%)was close to 1, with high reliability; Kappa=0.81, and the validation was consistent. When screening for moderately nonproliferative diabetic retinopathy, the sensitivity and specificity of non-mydriatic fundus photography were 90.6% and 95.5%; there was no significant difference between the results of non-mydriatic and the results of fundus photography after mydriasis. Compared to the gold standard group, the Youden index was 86.09%, the reliability is high, Kappa=0.86, and the test was consistency. <p>CONCLUSION:Non-mydriatic fundus photography can be used as a simple and accurate method for screening diabetic retinopathy. It is simple and easy to carry out without risk. It is easy to train specialist technicians for multi-point operation. With the help of today's convenient network, the image is transmitted to an experienced ophthalmologist for reading and diagnosis, which is convenient and fast, so that the patient can be diagnosed and treated nearby, which has positive significance for the society.
ABSTRACT
Traditional Chinese Medicine (TCM) has distinctive traditional features and unique therapeutic advantages.The characteristics of TCM including long history, rich theory, efficacy diversity, complex chemical composition, fuzzy mechanism, leading health care, compound-based, dose confidential, and dialectical pharmacy and so on, but TCM research findings with few practical applications now. We need a profound understanding of the characteristics of TCM and Chinese medicine research and application of full advantage of clear objectives that to accurate selection of TCM research focus and appropriate methods, creative design scheme of TCM. In this way, we may have satisfied the anticipated target about TCM and TCM academic truly promote the maintenance of health. In the medicine industry is bound to promote the great development of TCM to the world.
ABSTRACT
Objective To investigate the effect of total laparoscopic hysterectomy (LTH) and laparoscopic assisted vaginal hysterectomy (LAVH) for hysterectomy. Methods From February 2015 to February 2017, 182 patients with total hysterectomy were enrolled, among them, LTH was performed in 97 patients, and LAVH was performed in 85 patients, the operation time, intraoperative blood loss, the length of scar, postoperative anal exhaust time and so on were observed in the two groups, C reactive protein (CRP), interleukin -2 (IL-2) and IL-6 were detected before and after operation in two groups. Results In group LTH, the amount of bleeding and the length of scar were (104.33 ± 40.20) ml and (2.03 ± 0.84) cm respectively, which were significantly lower than those in group LAVH (P < 0.05); There was no significant difference between LTH group and LAVH group in postoperative anal exhaust time, hospital stay, postoperative analgesia and hospitalization costs (P > 0.05); The CRP and IL-6 in the LTH group postoperative were (26.43 ± 6.11) mg/L and (40.04 ± 11.03) ng/ml, significantly lower than those in LAVH group (P < 0.05), while IL-2 was (44.20 ± 12.29) ng/ml, was significantly higher than that of the control group (P < 0.05); The incidence of postoperative complications in LTH group was 6.19%, which was significantly lower than that of LAVH group (P < 0.05). Conclusion LTH is a safe and reliable method for hysterectomy, has the advantages of less complications, less influence on immune function and so on, is worthy of clinical application.
