ABSTRACT

OBJECTIVE To discuss medical insurance access and pricing methods for multi-indication drugs. METHODS The access situation of multi-indication drugs in China’s medical insurance negotiation over the years was sorted out. Referring to the economic theory of value-based pricing and the relevant experience of other countries, five applicable pricing methods of 3 categories for multi-indication drug in China were summarized. Taking ceftazidime-avibactam(CAZ-AVI) as an example, cost- utility analyses were performed for different indications, and appropriate pricing methods were applied. RESULTS & CONCLUSIONS All multi-indication drugs in China adopted a single pricing method. The pricing methods that could be explored include product-based pricing, such as single pricing based on the lower-value indication or mixed/weighted single pricing; indication-based pricing, such as developing a new agreement for single pricing under different discounts and listing with different brands and pricing of the same medicine for different indications; and compensation for access restrictions. Each method has its advantages and limitations. The case of CAZ-AVI showed that it is necessary to estimate the value of each indication for multi- indication drugs, and comprehensively consider appropriate access conditions and pricing methods based on value. Although single pricing is simple to operate, it is different to reflect the value entirely. The indication-based pricing and compensation for access restrictions all depend on the information collection system and the cooperation of multiple departments. China is supposed to carry out the value-based pricing of multi-indication drugs and constantly explore reasonable access methods to improve overall social welfare.

ABSTRACT

With the wide application of tyrosine kinase inhibitor (TKI), to obtain treatment-free remission (TFR) has gradually become the long-term goal for patients with chronic myelogenous leukemia (CML). Self-renewing leukemia stem cells during disease progression are related with the recurrence, and surveillance of residual leukemic cells is hypothesized to be one of the critical factors in successful TFR. On the way to obtain TFR, many breakthroughs have been made in innate and adaptive immunity of CML cells. This paper reviews the immune function of CML patients, the role of the immune markers in maintaining TFR, and the exploration of TKI combined with new immunomodulator therapy to achieve a greater degree of TFR.

ABSTRACT

Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

ABSTRACT

Objective: To investigate the characteristics, risk factors and outcomes of thalassemia major (TM) children with pericardial effusion (PE) after allo-geneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Clinical data of 446 TM children received allo-HSCT at Shenzhen Children's Hospital between January 2012 and December 2020 were analyzed retrospectively. Patients were divided into PE and non-PE group according to the occurrence of PE. Chi-square tests were used to investigate the risk factors that were associated with the development of PE. Kaplan-Meier method was used for survival analysis of the 2 groups. Results: Twenty-five out of 446 patients (5.6%) developed PE at a time of 75.0 (66.5, 112.5) days after allo-HSCT. Among these patients, 22 cases (88.0%) had PE within 6 months after allo-HSCT and 19 patients (76.0%) had PE within 100 days after allo-HSCT. The diagnoses of PE were confirmed using echocardiography. Pericardial tamponade was observed in only 1 patient, who later undergone emergency pericardiocentesis. The rest of patients received conservative managements alone. PE disappeared in all patients after treatment. Risk factors that were associated with the development of PE after allo-HSCT included the gender of patients, the type of transplantation, the number of mononuclear cells (MNC) infuse, pulmonary infection after HSCT and transplantation associated thrombotic microangiopathy (TA-TMA) (χ²=3.99, 10.20, 14.18, 36.24, 15.03, all P<0.05). In 239 patients that received haploidentical HSCT, the development of PE was associated with the gender of patients, pulmonary infection after HSCT and TA-TMA (χ²=4.48, 20.89, 12.70, all P<0.05). The overall survival rates of PE and non-PE groups were 96.0% (24/25) and 98.6% (415/421). The development of PE was not associated with the overall survival of TM children after allo-HSCT (χ²=1.73, P=0.188). Conclusions: PE mainly develop within 100 days after allo-HSCT in pediatric TM recipients. Haploidentical grafts, female gender, pulmonary infection after HSCT and TA-TMA are the main risk factors associated with PE development after transplant. However, the presence of PE don't have a significant impact on the outcomes of pediatric TM patients after allo-HSCT.

ABSTRACT

Objective:To explore the risk factors involved in gastritis, gastric intraepithelial neoplasia (GIN) and gastric cancer in Shihezi area.Methods:A total of 7 110 Han nationality patients who underwent gastroscopy at the First Affiliated Hospital of Shihezi University School of Medicine from January 2012 to December 2016 were selected as the research subjects. The data of patients were obtained through medical records and questionnaires. After excluding diseases related to esophagus and duodenum, a total of 4 429 cases were included in the retrospective analysis. Of which, 4 249 were gastritis, 93 were GIN, and 87 were gastric cancer. χ2 test, rank-sum test or Fisher exact probability method were used to analyze the differences of various factors in gastritis, GIN and gastric cancer. Univariate and multivariate logistic regression analysis were used to screen the risk factors for gastritis progression to GIN and gastric cancer. Results:χ2 test and rank sum test showed that there were statistically significant differences in gender, age, history of digestive diseases and distribution of Helicobacter pylori ( HP) infection among the groups of gastritis, GIN and gastric cancer ( P<0.05). The proportion of HP infection decreased gradually with the disease severity. Multivariate logistic regression analysis showed that male ( P<0.001, OR=2.251, 95% CI: 1.461-3.470), elderly ( P<0.001, OR=4.829, 95% CI: 2.241-10.409), a family history of gastric cancer ( P=0.002, OR=3.227, 95% CI: 1.537-6.774) and a history of digestive diseases ( P=0.034, OR=1.644, 95% CI: 1.037-2.607) were independent risk factors for gastritis progression to GIN. Male ( P<0.001, OR=3.254, 95% CI: 2.026-5.225), middle-aged ( P=0.022, OR=2.688, 95% CI: 1.153-6.265) and elderly ( P=0.002, OR=4.734, 95% CI: 1.750-12.807) were independent risk factors for gastritis progression to gastric cancer. In stratified analysis to exclude age and gender, smoking ( P=0.028, OR=4.060, 95% CI: 1.160-14.202) was found to be a risk factor for gastritis progression to GIN in young adults, and obesity ( P=0.032, OR=3.869, 95% CI: 1.121-13.356) was found to be a risk factor for gastritis progression to gastric cancer in women. Conclusion:The degree of HP infection in gastric tissues is negatively correlated with the severity of gastric diseases, suggesting that HP infection may be an early event inducing gastric cancer. Male, the elderly, people with a family history of gastric cancer and a history of digestive diseases, and young smokers in Shihezi are more likely to develop GIN, and male, middle-aged, elderly, and obese women are at increased risk of gastric cancer.

ABSTRACT

Objective:To summarize the prenatal diagnosis and postnatal follow-up of 15q11.2 BP1-BP2 microdeletion syndrome (Burnside-Butler syndrome, BBS), and provide a reference for the management of BBS.Methods:A retrospective analysis was performed on 27 singleton pregnancies with fetal BBS that were prenatally diagnosed by single nucleotide polymorphism(SNP) array of amniotic fluid in Wuxi Maternity and Child Health Care Hospital from January 2017 to September 2021. Prenatal diagnosis indications, serological screening, prenatal ultrasound features, SNP array results, and postnatal growth and development were described and summarized.Results:(1) Of the 27 cases, the indications of prenatal diagnosis in 14 cases were abnormal sonographic findings, including eight cases with increased nuchal translucency, two with cleft lip and palate/alveolar process cleft, one with fetal multiple joint contracture syndrome, one with fetal right diaphragmatic hernia and single umbilical artery, one with suspected fetal duodenal atresia and one with nasal bone absence. Other indications included high risk of Down syndrome by serological screening in six cases, history of adverse pregnancy in six cases, and advanced age in one case. (2) Karyotyping of amniotic fluid in these 27 BBS fetuses showed normal results and SNP array indicated the deletion range of 311.8-855.3 kb. Parental verification of 23 cases confirmed one was a new mutation, seven were inherited from the father and 15 from the mother. (3) Five pregnancies were terminated in the second trimester and the remaining 22 cases were live births. (4) The median follow-up of the 22 children was 1 year 8 months (range 0.5 months to 4 years 3 months), which found low body weight and/or growth retardation in six cases, low body weight with language retardation in one case, low body weight with growth retardation and hyperactive behavior in one case, language retardation with left ear appendage in one case, cleft palate accompanied by duodenum/cleft lip and alveolar cleft in two cases without abnormal development after surgical treatment, and no abnormal growth in the remaining 11 cases.Conclusion:For BBS fetuses, the proportion of ultrasound abnormalities is high but with a low specificity in prenatal diagnosis, and the risk of abnormal postnatal growth and development/behavior is high, which requires continuous monitoring.

ABSTRACT

Objective:To investigate the ultrasonographic and genetic features of Cri-du-chat syndrome (CDCS).Methods:In this retrospective study, cases with CDCS diagnosed in Wuxi Maternal and Child Health Care Hospital from 2004 to 2021 and with complete data were reviewed to describe and analyze the maternal serum prenatal screening, non-invasive prenatal testing (NIPT), ultrasound, genetic examination data, and pregnancy outcomes.Results:All cases were diagnosed by karyotype analysis, seven of them were diagnosed prenatally through amniotic fluid, and four were diagnosed after birth through peripheral blood. Five of the seven cases diagnosed prenatally had an abnormal serological screening, including two cases with 5p- indicated by NIPT. Of the 11 cases, prenatal ultrasonography showed cerebellar transverse diameter less than -2 SD in eight cases, including four with cerebellar hypoplasia (CH), two with fetal growth restriction, and two with cranial diameters less than -2 SD. One case was shown with an increased nuchal translucency, accompanying bilateral choroid plexus cysts of the lateral ventricles, and suspected persistent left superior vena cava. No obvious ultrasound abnormality was observed in the remaining two cases. Among the seven cases diagnosed prenatally, excluding one case that refused parental verification, further single nucleotide polymorphism array (SNP array) showed that all six cases inherited the de novo mutations from the parents. The cytogenetic analysis found the breakpoints at 5p13, 5p14, and 5p15 in five, three, and three cases. All seven pregnancies were terminated in the second trimester. Four children diagnosed postnatally presented with CDCS phenotype during the follow-up at three years old. Conclusions:Fetal CDCS should be considered with CH detected by prenatal ultrasonography, though the correlation between CH and CDCS still needs further investigation. Gene mapping with an SNP array is helpful for phenotypic profiling and genetic counseling.

ABSTRACT

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis, closely associated with the immune system. Its pathogenesis is currently not clear. The lack of specificity in the clinical manifestations and histopathological changes of PG leads to a long clinical diagnosis cycle and even misdiagnosis, which is easy to delay treatment or promote the deterioration of ulcer wound. The diagnosis of this disease is still very difficult, which poses a great challenge to wound repair practitioners. This article reviews the research advances on the pathophysiology, clinical features, and diagnosis of PG in recent years, with the aim of providing reference for relevant clinical practitioners.

ABSTRACT

BACKGROUND@#Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.@*METHODS@#The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD.@*RESULTS@#A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05).@*CONCLUSION@#Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

ABSTRACT

Chronic myelogenous leukemia (CML) is a myeloproliferative disease characterized by heterotopic Ph chromosome. Tyrosine kinase inhibitor (TKI) has significantly improved the prognosis of patients with CML. Cytogenetic and molecular monitoring for assessing the therapeutic efficacy of TKI to guide disease management has become an important component of CML therapy. However, the expanded genomic analysis of the disease diagnosis, transformation and drug resistance has not been fully explored in CML research. The paper reviews the frequency and type of gene mutations at initial diagnosis and the time of treatment failure and transformation, and investigates the relationship between genetic mutations and the prognosis of CML patients in the diagnosis and treatment.

ABSTRACT

Objective:To investigate the pathogenic gene locus and prenatal genetic diagnosis of 54 families with oculocutaneous albinism (OCA).Methods:This retrospective study enrolled 54 OCA probands and their families from Gansu Province Maternal and Child Health Care Hospital from May 2014 to May 2020. TYR gene variation screening was performed on the probands by Sanger sequencing. Those with negative results were analyzed by high-throughput sequencing, and further verification was performed on their parents by Sanger sequencing. Among the 54 families, 15 ml amniotic fluid were collected from 16 women at 18-21 gestational weeks in their subsequent pregnancy. Sanger sequencing combined with short tandem repeats sequence for linkage analysis were performed for genetic analysis. All data were analyzed using descriptive statistical analysis. Results:Out of the 54 OCA probands, 48 were diagnosed as OCA1, five were OCA2 and one was OCA4 based on the Sanger sequencing and high-throughput sequencing detection. A total of 26 different variation sites were involved in the 48 OCA1 probands, including 15 missense mutations, five nonsense mutations, three splicing mutations, and three frame-shift mutations, among which, c.929insC (29%, 28/96) was the most frequent mutation, followed by c.896G>A (11%, 11/96), c.832C>T (8%, 8/96) and c.703T>C (5%, 5/96). The diagnosis was confirmed in all 16 fetuses in the 16 families that underwent prenatal diagnosis. Five of them were affected and their mothers chose to terminate the pregnancies, the other 11 pregnancies continued to delivery, including seven heterozygous carriers and four fetuses without the same pathogenic allele as the proband. Maternal contamination was excluded in all prenatal samples using short tandem repeat for linkage analysis. All 11 children were in good health during telephone follow-up one month after birth. Postnatal validations were consistent with the prenatal tests.Conclusions:Genetic diagnosis could accurately identify various types of OCA and help to provide prenatal diagnosis and fertility consultation for subsequent pregnancies.

ABSTRACT

OBJECTIVE:To provide referenc e for selectin g antitumor drugs economic evaluation models and improving the quality of evidence for antitumor drugs economics evaluation in China. METHODS :A systematic search of the antitumor drug health technology evaluation (pCODR)reports were conducted on the official website of the Canadian Agency for Drugs and Technologies in Health (CADTH). The search time was limited to Jan. 1st,2015 to Sep. 6th,2020. The basic information ,model types and structure ,and key limitations were extracted and summarized. RESULTS & CONCLUSIONS :A total of 185 pCODR reports were finally retrieved ,involving 114 types of tumor indications and 98 types of antitumor drugs. The number of CADTH antitumor drugs economics evaluations in the past 5 years had shown an increasing trend. Among 137 pCODR reports with final economic guidance report ,98 reports(71.5%)adopted the PartSA model ,21 reports(15.3%)used the Markov model ,and some reports(6 reports,4.3%)used both PartSA and Markov models to explore the uncertainty of the model structure. In terms of model health status setting ,86 reports(62.8%)used three-state models to evaluate the economy of different anti tumor drugs ,and 16 reports(11.7%)used no less than four health states to simulate the outcome of disease state. However ,there were still some problems in CADTH models ,such as the unreasonable choice of research time limit ,the unreasonable extrapolation method or uncertain extrapolation results of efficacy (survival)data,the uncertainty of efficacy data obtained by indirect comparison ,and some assumptions or parameter settings did not conform to the actual diagnosis and treatment environment. In view of the advantages of PartSA model ,it is suggested that PartSA model or Markov model combined with PartSA model should be used first to verify the uncertainty of model structure in the future economic evaluation of antitumor drugs ;reasonable settings of key model parameters should be considered to improve the quality of evidence for antitumor drugs economics evaluation in China.

ABSTRACT

OBJECTIVE@#Patients with 22q11.2 microduplications have highly variable clinical phenotypes. The clinical manifestations and prognosis of 19 fetuses carrying 22q11.2 microduplications were analyzed.@*METHODS@#The fetuses were analyzed by single nucleotide polymorphism array (SNP array), which was followed by parental validation. Pregnancy outcome and clinical features of the newborns were analyzed in order to delineate genotype-phenotype correlation.@*RESULTS@#Two fetuses were identified by karyotyping analysis of amniotic fluid samples. SNP array revealed that all have carried a 468.8 kb~3.4 Mb duplication in 22q11.2 region. Two couples have refused parental verification. Seven cases were inherited from the mother, 6 were from the father, and 4 cases were de novo in origin. Three couples opted termination of the pregnancy. One fetus perished at birth. Five newborns showed delayed growth, the remaining 10 were normal.@*CONCLUSION@#The prenatal phenotype of fetuses carrying 22q11.2 microduplications are nonspecific, and the phenotypes of survivors may become more diverse along with increased age. Professional evaluation and long-term follow-up should be recommended.

ABSTRACT

This study was to investigate the chemical constituents from the aerial parts of Thymus przewalskii. The chemical consti-tuents were separated and purified by column chromatography on silica gel, ODS, Sephadex LH-20 and semi-prepared HPLC, and their structures were determined by physicochemical properties and spectroscopic data. Four flavanones were isolated from the ethanol extract of the aerial parts of T. przewalskii, and identified as(2S)-5,6-dihydroxy-7,8,4'-trimethoxyflavanone(1), 5,4'-dihydroxy-6,7-dimethoxyflavanone(2),(2S)-5,4'-dihydroxy-7,8-dimethoxyflavanone(3), sakuranetin(4), respectively. Compound 1 was a new compound and its configuration was determined by CD spectrum, compound 3 was natural product which was isolated for the first time and their configurations were determined by CD spectra. Compound 2 was isolated from the genus Thymus for the first time and compound 4 was isolated from T. przewalskii for the first time. Furthermore, cytotoxicity test was assayed for the four flavanones. They exhibited weak cytotoxicity against human lung cancer cells(A549), with the IC_(50) from 74.5 to 135.6 μmol·L~(-1).

ABSTRACT

Objective To systematically evaluate the efficacy and safety of different non-steroidal anti-inflammatory drugs (NSAIDs) in middle-aged and old Chinese patients with osteoarthritis(OA). Methods A systematic literature search was conducted through PubMed, Cochrane Library, CNKI, Wan Fang Data and VIP databases to collect randomized controlled trials with non-steroidal anti-inflammatory drugs in middle-aged to old Chinese OA patients. The search time was from the establishment of the database to November 17, 2020. Two researchers independently carried out literature screening, data extraction and literature quality evaluation. Bayesian network meta-analysis was conducted with R3.6.0 software. Results 28 RCTs were included with 2531 patients. Based on the last follow-up pain visual analogue scale (VAS) score, the ranking chart showed that Etoricoxib had the highest probability of having the lowest pain VAS score (88.55%). In terms of total effective rate, the ranking chart showed that the probability of Etoricoxib as first choice was the highest (92.49%). As far as safety, diclofenac sodium patch had the lowest adverse effects rate (59.10%). Conclusion The results of this study indicated that Etoricoxib was the most effective treatment for middle-aged and old Chinese OA patients. It can significantly reduce the OA pain. Diclofenac sodium patch had the least adverse effects.

ABSTRACT

Tumor has become the second most serious disease that threatens human health and life. Treating with chemical drugs (referred to as chemotherapy) is the most basic treatment, but most chemotherapeutic drugs cause damage to normal tissues. It is a difficult problem in the field of biomedical research that how to deliver anti-tumor drugs more efficiently, increase the concentration of drugs in tumor tissues, enhance the anti-tumor effect, and decrease the drug distribution in normal tissues to weaken the damage to normal tissues. In order to achieve the goals of accurate delivery of anti-tumor drugs and synergism and attenuation, the researchers used systematic evolution of ligands by exponential enrichment technology (SELEX technology) to screen aptamers that can specifically target tumor markers or tumor cells, and designed the novel liposome targeting drug delivery system with aptamers as targeting molecules (ligands). This paper briefly introduced nucleic acid aptamer technology and common tumor markers, and reviewed the research advances on the antitumor effect of aptamer-liposome drug delivery system. It will provide references for the selection of appropriate tumor markers as targets and the application of aptamer technology in the research and development of high-efficiency and low-toxicity liposome targeting agents of anti-tumor traditional Chinese medicine. Meanwhile, it is of great significance for promoting the application of aptamer technology in targeted drug delivery systems.
