ABSTRACT

Objective: To explore the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) ratio with the severity of coronary artery disease and 2-yeat outcome in patients with premature coronary heart disease. Methods: This prospective, multicenter, observational cohort study is originated from the PROMISE study. Eighteen thousand seven hundred and one patients with coronary heart disease (CHD) were screened from January 2015 to May 2019. Three thousand eight hundred and sixty-one patients with premature CHD were enrolled in the current study. According to the median LDL-C/HDL-C ratio (2.4), the patients were divided into two groups: low LDL-C/HDL-C group (LDL-C/HDL-C≤2.4, n=1 867) and high LDL-C/HDL-C group (LDL-C/HDL-C>2.4, n=1 994). Baseline data and 2-year major adverse cardiovascular and cerebrovascular events (MACCE) were collected and analyzed in order to find the differences between premature CHD patients at different LDL-C/HDL-C levels, and explore the correlation between LDL-C/HDL-C ratio with the severity of coronary artery disease and MACCE. Results: The average age of the low LDL-C/HDL-C ratio group was (48.5±6.5) years, 1 154 patients were males (61.8%); the average age of high LDL-C/HDL-C ratio group was (46.5±6.8) years, 1 523 were males (76.4%). The number of target lesions, the number of coronary artery lesions, the preoperative SNYTAX score and the proportion of three-vessel coronary artery disease in the high LDL-C/HDL-C group were significantly higher than those in the low LDL-C/HDL-C group (1.04±0.74 vs. 0.97±0.80, P=0.002; 2.04±0.84 vs. 1.85±0.84, P<0.001; 13.81±8.87 vs. 11.70±8.05, P<0.001; 36.2% vs. 27.4%, respectively, P<0.001). Correlation analysis showed that there was a significant positive correlation between LDL-C/HDL-C ratio and preoperative SYNTAX score, the number of coronary artery lesions, the number of target lesions and whether it was a three-vessel coronary artery disease (all P<0.05). The 2-year follow-up results showed that the incidence of MACCE was significantly higher in the high LDL-C/HDL-C group than that in the low LDL-C/HDL-C group (6.9% vs. 9.1%, P=0.011). There was no significant difference in the incidence of all-cause death, cardiac death, myocardial infarction, stroke, revascularization and bleeding between the two groups. Cox multivariate regression analysis showed that the LDL-C/HDL-C ratio has no correlation with 2-year MACCE, death, myocardial infarction, revascularization, stroke and bleeding events above BARC2 in patients with premature CHD. Conclusion: High LDL-C/HDL-C ratio is positively correlated with the severity of coronary artery disease in patients with premature CHD. The incidence of MACCE of patients with high LDL-C/HDL-C ratio is significantly higher during 2 years follow-up; LDL-C/HDL-C ratio may be an indicator for evaluating the severity of coronary artery disease and long-term prognosis in patients with premature CHD.

ABSTRACT

The intangible cultural heritage of traditional Chinese medicine (TCM) is the essence of the treasure house of TCM. The State Council has successively announced five batches of national intangible cultural heritage representative projects and lists of inheritors, including 182 projects and 130 inheritors in traditional medicine. A systematic analysis of current traditional medicine projects and inheritors has found problems such as unreasonable categorization, obvious category bias, large regional distribution gap, serious aging of the inheritance team, and under emphasizing in ethnic minority medicine. Therefore, it is suggested to adjust categories, balance development, rationalize categories, and increase attention, thereby providing reference for the protection of TCM intangible cultural heritage.

ABSTRACT

Glucocorticoid-induced osteoporosis (GIOP) is a skeletal disease characterized by decreased bone strength and increased fracture risk associated with long-term glucocorticoid use. GIOP is the most common secondary osteoporosis that critically affects the quality of life of patients. Currently, the incidence of GIOP in China remains high, with insufficient awareness and lack of prevention and treatment norms. Therefore, the Chinese Rheumatology Association has established this standard based on domestic and international experience, with the aim of raising awareness of prevention and treatment among clinicians, guiding the standardized diagnosis and treatment of this disease, and improving the overall prognosis of patients with GIOP.

ABSTRACT

Sj?gren′s syndrome (SS) is a chronic systemic autoimmune disease characterized by lymphocyte proliferation and progressive exocrine gland damage. In addition to the impairment of salivary and lacrimal gland function, SS can present with multi-system and multi-organ involvement, accompanied by autoantibodies in serum and hyperimmunoglobulinemia. SS can be divided into primary and secondary forms based on the absence or presence, respectively, of concurrent connective tissue diseases such as systemic lupus erythematosus and rheumatoid arthritis. Based on evidence and guidelines from China and other countries, the Chinese Rheumatology Association drafted standardized criteria for the diagnosis and treatment of primary SS. The objectives were to standardize the detection and interpretation of key indicators for the diagnosis of SS, including serum anti-SSA antibody and labial gland pathology, suggest the use of the widely accepted European League Against Rheumatism (EULAR)-SS disease activity index for the evaluation of the disease, and standardize the rational management of SS patients with topical and systemic therapies.

ABSTRACT

Polymyalgia rheumatica (PMR) is a syndrome characterized by pain and morning stiffness in the neck and shoulder and pelvic girdles, as well as raised acute-phase reactants, with or without systemic symptoms, such as fever. Giant cell arteritis (GCA) is a systemic vasculitis of unclear etiology that involves systemic arteries, principally affecting medium- and large-sized arteries with skipped, segmental alterations and granulomatous vasculitis seen on histopathology. In China, epidemiological data describing GCA are still limited; thus, the prevalence might be underestimated. The involvement of vessels in GCA can cause irreversible visual impairment or loss and stroke, which are serious complications. PMR is three times more prevalent than GCA, and other specific diseases should be excluded before the diagnosis is established. PMR symptoms can be present in 40%-60% of patients with GCA. Conversely, GCA can develop in 15% of patients with PMR. Chinese Rheumatology Association, based on the clinical diagnosis and treatment guidelines in 2005, utilizing the experience and guidelines of diagnosis and treatment at home and abroad, formulated this specification to standardize the diagnosis and treatment of GCA and PMR and improve the patient′s prognosis.

ABSTRACT

Hemophagocytic syndrome (HPS), which is currently named as hemophagocytic lymphohistiocytosis (HLH), is a hyperinflammatory syndrome characterized by persistent fever, hepatosplenomegaly, pancytopenia and hemophagocytosis found in bone marrow, liver, spleen and lymph nodes due to excessive activation of macrophages and cytotoxic T cells. Macrophage activation syndrome (MAS) is a specific form of HLH induced by autoinflammatory/autoimmune disorders which can be life-threatening and requires multiple disciplines. In order to improve clinicians′ understanding of MAS and standardize the clinical diagnosis and treatment practice of MAS, the rheumatology branch of Chinese Rheumatology Association organized domestic experts to formulate the diagnosis and treatment standard, in order to improve the diagnosis and treatment level of MAS and improve the prognosis of patients.

ABSTRACT

Objective:To investigate the value of pre-therapy 18F-FDG PET/CT radiomic models in differentiating epidermal growth factor receptor (EGFR) exon 19 deletion from exon 21 L858R missense in patients with non-small cell lung cancer (NSCLC). Methods:A total of 172 patients with EGFR mutant NSCLC (54 males, 118 females, age: (56.2±12.5) years) in the Fourth Hospital of Hebei Medical University between January 2015 and November 2019 were retrospectively included. Exon 19 mutation was found in 75 patients and exon 21 mutation was identified in 97 patients. The patients were divided into training set ( n=121) and validation set ( n=51) in a 7∶3 ratio by using random number table. The LIFEx 4.00 package was used to extract texture features of PET/CT images of lesions. The least absolute shrinkage and selection operator (LASSO) algorithm was used for feature screening. Three machine learning models, namely logistic regression (LR), random forest (RF), and support vector machine (SVM) models, were constructed based on the selected optimal feature subsets. The ROC curve analysis was performed to assess the predictive performance of those models. Finally, decision curve analysis (DCA) was used to evaluate the clinical value of the models. Results:Nine radiomics features, including 6 PET features (histogram (HISTO)_Kurtosis, SHAPE_Sphericity, gray level run length matrix (GLRLM)_ low gray-level run emphasis (LGRE), GLRLM_ run length non-uniformity (RLNU), neighborhood grey level different matrix (NGLDM)_Contrast, gray level zone length matrix (GLZLM)_ short-zone low gray-level emphasis (SZLGE)), and 3 CT features (gray level co-occurrence matrix (GLCM)_Correlation, GLRLM_ run percentage (RP), NGLDM_Contrast), were screened by LASSO algorithm. Three machine learning models had similar predictive performance in the training and validation sets: AUCs for the RF model were 0.79, 0.77, and those for the SVM model were 0.76, 0.75, for the LR model were 0.77, 0.75. The DCA showed that the 3 machine learning models had good net benefits and clinical values in predicting EGFR mutation subtypes.Conclusion:18F-FDG PET/CT radiomics provide a non-invasive method for the identification of EGFR exon 19 deletion and exon 21 L858R missense mutations in patients with NSCLC, which may help the clinical decision-making and the formulation of individualized treatment plan.

ABSTRACT

Objective:To investigate the effect of laparoscopic ovarian cystectomy on anti-Mullerian hormone (AMH) level, ovarian response to gonadotropin stimulation and pregnancy rate for in vitro fertilization (IVF) patients with benign ovarian cysts.Methods:Patients with benign ovarian cysts who were admitted for cystectomy and had undergone IVF treatment were enrolled in the study. There were 373 participants with ovarian cysts underwent laparoscopic ovarian cystectomy in the experimental group. According to duration of post-surgery, there were four sub-groups: 1 year post-surgery (1Y POST), 2 years post-surgery (2Y POST), 4 years post-surgery (4Y POST) and ≥5 years post-surgery (≥5Y POST) in the experimental group. According to histopathologic types of ovarian cysts, there were two sub-groups: ovarian endometriotic cysts and ovarian non-endometriotic cysts. Two hundreds and three patients with no history of ovarian cysts and ovarian surgery were in the control group. The level of AMH and basic concentrations of follicle stimulating hormone (FSH), luteinizing hormone (LH), progesterone (P), estradiol (E 2) were measured. Antral follicle counts (AFC) were calculated. There were other study variables: total dose of gonadotropins, duration of ovarian stimulation, the number of oocyte retrieved, the number of embryo obtained, blastocyst transfer rate and pregnancy rate. Results:The control group was matched as closely as possible to the experimental group, including age, body mass index and menstrual cycle (all P>0.05). Compared to the women in control group, the women in ovarian endometriotic cystectomy sub-group had significantly higher levels of basal FSH and basal P, lower level of AMH (all P<0.05); the women in ovarian endometriotic cysts sub-group had significantly higher dose of gonadotropins (all P<0.05); the women in ovarian endometriotic cysts ≥5Y POST sub-group had significantly lower number of oocyte retrieved, lower number of embryo obtained, lower blastocyst transfer rate, and lower pregnancy rate (all P<0.05). Compared to the women in control group, the women in ovarian non-endometriotic cysts sub-group had a significantly higher level of basal FSH and basal P (all P<0.05). The women in ovarian non-endometriotic cysts sub-group had lower level of AMH, higher dose of gonadotropins, lower number of oocyte retrieved, lower number of embryo obtained, lower rate of blastocyst transfer and lower rate of pregnancy than the control group but there were no statistically significant differences among them (all P>0.05). The women with unilateral ovarian endometriotic cysts had significantly lower number of oocyte retrieved on the side of surgery than another side ( P<0.05). Conclusions:In short term laparoscopic ovarian cystectomy has no significant effect on ovarian reserve. But with long-term follow-up ovarian reserve, ovarian response to gonadotropin stimulation and pregnancy rate are decreased. The effect of laparoscopic ovarian cystectomy in benign cysts on ovarian is associated with whether or not it is the surgical side.

ABSTRACT

Objective:To observe the lipid-lowering effect of atorvastatin on patients with acute cerebral infarction with different ATP-binding cassette subfamily B member 1(ABCB1) genotypes, and thus to provide clinical research evidence for individual application of atorvastatin in patients with acute cerebral infarction.Methods:From March 2021 to December 2021, 131 patients with acute cerebral infarction admitted to the Department of Neurology of Xuchang Central Hospital were included. The ABCB1 G2677T gene polymorphism rs2032582 of patients was detected by fluorescence staining in situ hybridization.Based on the detection results, patients were divided into GG group, GT group and TT group.All patients were given atorvastatin (20 mg/d) for lipid-lowering treatment.The levels of low density lipoprotein cholesterol(HDL-C), high density lipoprotein cholesterol(HDL-C), total cholesterol(TC)and triglyceride(TG) in serum of patients in the three groups before and 2 months after treatment were recorded and analyzed.The adverse drug reactions in the three groups were recorded. When the serum LDL-C level was less than 1.8 mmol/L, it was considered that the lipid-lowering treatment was effective.The binary Logistic regression analysis was used to explore the influencing factors of atorvastatin lipid lowering therapy.The software of SPSS 25.0 was used for statistical analysis.Results:There were 50 (38.17%), 49 (37.40%) and 32 (24.43%) patients in GG group, GT group and TT group, respectively. The serum TC levels of patients in GG group, GT group and TT group after treatment were (3.47±0.70) mmol/L, (3.59±1.09) mmol/L and (3.48±1.02) mmol/L, respectively, which were lower than those before treatment ((4.27± 0.99) mmol/L, (4.02±0.98) mmol/L and (4.03±1.31) mmol/L), all of which were statistically significant ( t=7.652, 3.092, 5.593, all P<0.01). The serum LDL-C levels in GG group, GT group and TT group after treatment were (1.89±0.53) mmol/L, (2.07±0.92) mmol/L and (1.96±0.79) mmol/L, respectively, which were lower than those before treatment ((2.87±0.92) mmol/L, (2.56±0.89) mmol/L and (2.55±1.11) mmol/L) ( t=9.896, 4.055, 5.980, all P<0.001). The differences of serum LDL-C level before and after treatment in GG group, GT group and TT group were (-0.97±0.69) mmol/L, (-0.50±0.86) mmol/L and (-0.59±0.56) mmol/L, respectively. The difference of serum LDL-C level before and after treatment in the three groups was statistically significant ( F=5.614, P=0.005). The difference of TC, TG and HDL-C before and after treatment was not statistically significant( F=2.783, 0.490, 1.677, all P>0.05). The binary Logistic regression analysis showed that ABCB1 G2677T gene type and staying up late were independent influencing factors for atorvastatin lipid-lowering therapy. The probability of effective lipid-lowering in GT patients with ABCB1 G2677T gene was 27.9% of that in GG patients ( OR=0.279, 95% CI: 0.110-0.709, P=0.007), and the probability of TT type patients was 33.8% of GG type patients ( OR=0.338, 95% CI: 0.121-0.943, P=0.038). The probability of effective lipid-lowering in patients who had the habit of staying up late was 26.4% of the patients who did not stay up late ( OR=0.264, 95% CI: 0.118-0.591, P=0.001). There was no significant difference in the total incidence of adverse drug reactions among the three groups( χ2=0.868, P=0.648). Conclusion:The lipid-lowering effect in patients with GG type of ABCB1 G2677T is better than that of GT type and TT type when atorvastatin is used to treat patients with acute cerebral infarction.

ABSTRACT

Objective: To investigate the clinical features and long-term prognosis of primary biliary cholangitis (PBC) in patients with past hepatitis B virus (HBV) infection. Methods: 353 cases with PBC who visited the Liver Disease Center of Beijing Friendship Hospital Affiliated to Capital Medical University between January 2000 and January 2018 were retrospectively analyzed and were divided into the past HBV infection group (156 cases) and the no HBV infection group (197 cases). The two groups' baseline clinical features were compared. Ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, and long-term liver transplantation-free survival rate were compared through outpatient and telephone follow-up. Results: PBC with past HBV infection had a significantly reduced female proportion compared to the no HBV infection group (91.9% vs. 79.5%, P = 0.001). However, there were no statistically significant differences in age, biochemical indices, immunological indicators, platelet count, cirrhosis proportion, and others. Ursodeoxycholic acid biochemical response rate was reduced in patients with past HBV infection at the end of one year of treatment, but the difference was not statistically significant (65.8% vs. 78.2%, P = 0.068). In addition, there were no statistically significant differences between the GLOBE score (0.57 vs. 0.59, P = 0.26) and UK-PBC 5-year (2.87% vs. 2.87%, P = 0.38), 10-year (9.29% vs. 8.2%, P = 0.39) and 15-year liver transplantation rates (16.6% vs. 14.73%, P = 0.39). Lastly, the overall 5-year liver transplantation-free survival rate had no statistically significant difference between the two groups of patients (86.4% vs. 87.5%, P = 0.796). Conclusion: Primary biliary cholangitis had no discernible effect in terms of age at onset, biochemical indices, immunological indicators, cirrhosis proportion, ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, or overall liver transplantation-free survival rate in patients with past hepatitis B virus infections.

ABSTRACT

Objective To explore the risk factors of unplanned readmission in patients with acute myocardial infarction in plateau area. Methods The convenience sampling method was used to select 220 patients with acute myocardial infarction in the hospital's internal medicine department from January 2020 to May 2021. The patients were divided into two groups according to whether they had unplanned readmission within one year, 79 patients were included in readmission group, and 141 patients without unplanned readmission were included in non-readmission group. Clinical data of the 220 patients with acute myocardial infarction in plateau area were collected by reviewing electronic medical records, and laboratory examination and angiography examination were performed 1 day before discharge. Univariate and multivariate logistic regression analysis were carried out, and ROC curve risk prediction model was established. Results There were statistically significant differences in age, history of myocardial infarction, history of PCI, history of stroke, blood calcium, and Kilip cardiac function between the two groups (P < 0.05). Logistic regression analysis showed that age ≥60 years old, history of myocardial infarction, history of PCI, history of stroke, blood calcium and Kilip cardiac function grading were positively correlated with unscheduled readmission (P < 0.05). The ROC curve was drawn with the occurrence of unplanned readmission as the state variable. The AUC area was 0.801, the predictive sensitivity was 88.94%, and the specificity was 57.92%. Conclusion Unplanned readmission of AMI patients in plateau areas is related to multiple factors. It is necessary to identify high-risk groups as early as possible in combination with risk factors and develop individualized intervention measures.

ABSTRACT

AIM:To compare the curative effect of different surgical methods combined with Toric intraocular lens(IOL)implantation on age-related hard nuclear cataract.METHODS:According to retrospective study, 104 patients(104 eyes)with age-related hard nuclear cataract confirmed in the hospital between January 2020 and December 2021 were enrolled. They were divided into phacoemulsification group(52 eyes, phacoemulsification combined with Toric IOL implantation)and small-incision group(52 eyes, small-incision split nuclear technique in horizontal space combined with Toric IOL implantation)according to different surgical methods. The best corrected distance visual acuity(BCDVA), corneal astigmatism, number of corneal endothelial cells, proportion of normal hexagonal cells, tear film function and complications were compared between the two groups.RESULTS:There was no significant difference in BCDVA(LogMAR)between the two groups before and at 3mo after surgery(all P&#x003E;0.05), while BCDVA(LogMAR)was better in small-incision group than phacoemulsification group at 1wk after surgery(0.15±0.04 vs. 0.20±0.05, P&#x003C;0.001). The corneal astigmatism of the patients in both groups was lower at 1wk and 3mo after surgery than that before surgery, and it was lower at 3mo than 1wk after surgery(all P&#x003C;0.05), while there was no significant difference in corneal astigmatism between the two groups before and after surgery(all P&#x003E;0.05). At 1wk and 3mo after surgery, number of corneal endothelial cells in small-incision group was more than that in phacoemulsification group(1wk after surgery: 2363.8±315.3 vs. 2231.4±326.4 cells/mm2, P&#x003C;0.05; 3mo after surgery: 2414.6±245.7 vs. 2322.9±221.0 cells/mm2, P&#x003C;0.05). Before and at 1wk after surgery, there was no significant difference in the proportion of normal hexagonal cells between the two groups(all P&#x003E;0.05). At 3mo after surgery, proportion of normal hexagonal cells in small-incision group was higher than that in phacoemulsification group(21.77%±1.91% vs. 20.59%±1.65%, P&#x003C;0.001). Before and at 3mo after surgery, there was no difference in break up time(BUT)or ocular surface disease index(OSDI)score between the two groups(P&#x003E;0.05). At 1wk after surgery, BUT in small-incision group was longer than that in phacoemulsification group(6.8±0.8 vs. 5.9±1.0s, P&#x003C;0.001)and OSDI score was lower than that in phacoemulsification group(17.62±5.47 vs. 20.34±6.18 points, P&#x003C;0.05). The incidence of postoperative complications in small-incision group was lower than that in phacoemulsification group(3.9% vs. 17.3%, P&#x003C;0.05).CONCLUSION: Small-incision split nuclear technique in horizontal space combined with Toric IOL implantation can significantly improve visual acuity and astigmatism in patients with age-related cataract, with slight damage to corneal endothelium and tear film function.

ABSTRACT

Galactinol synthase (GolS) genes play important roles in plant response to abiotic stress. In this research, the plant expression vector of soybean GmGolS2-2 gene was constructed and transformed into tobacco to study the drought tolerance of transgenic tobacco. A GmGolS2-2 gene with 975 bp coding sequence was cloned from soybean leaves by reverse transcription-polymerase chain reaction (RT-PCR). GmGolS2-2 was linked to the plant expression vector pRI101 by restriction enzyme sites Nde Ⅰ and EcoR Ⅰ, and transformed into tobacco by leaf disc method. Genomic DNA PCR and real-time PCR showed that three GmGolS2-2 transgenic tobacco plants were obtained. The growth status of GmGolS2-2 transgenic tobacco under drought stress was better than that of wild-type tobacco. After drought stress treatment, the electrolyte leakage and malondialdehyde content of transgenic tobacco were lower than those of wild-type tobacco, but the proline content and soluble sugar content were higher than those of wild-type tobacco. The results of real-time PCR showed that the heterologous expression of GmGolS2-2 increased the expression of stress-related genes NtERD10C and NtAQP1 in transgenic tobacco. The above results indicated that GmGolS2-2 improved drought resistance of transgenic tobacco.

ABSTRACT

Objective: To investigate the effects of human umbilical cord mesenchymal stem cells (hUCMSCs) combined with autologous Meek microskin transplantation on patients with extensive burns. Methods: The prospective self-controlled study was conducted. From May 2019 to June 2022, 16 patients with extensive burns admitted to the 990th Hospital of PLA Joint Logistics Support Force met the inclusion criteria, while 3 patients were excluded according to the exclusion criteria, and 13 patients were finally selected, including 10 males and 3 females, aged 24-61 (42±13) years. A total of 20 trial areas (40 wounds, with area of 10 cm×10 cm in each wound) were selected. Two adjacent wounds in each trial area were divided into hUCMSC+gel group applied with hyaluronic acid gel containing hUCMSCs and gel only group applied with hyaluronic acid gel only according to the random number table, with 20 wounds in each group. Afterwards the wounds in two groups were transplanted with autologous Meek microskin grafts with an extension ratio of 1∶6. In 2, 3, and 4 weeks post operation, the wound healing was observed, the wound healing rate was calculated, and the wound healing time was recorded. The specimen of wound secretion was collected for microorganism culture if there was purulent secretion on the wound post operation. In 3, 6, and 12 months post operation, the scar hyperplasia in wound was assessed using the Vancouver scar scale (VSS). In 3 months post operation, the wound tissue was collected for hematoxylin-eosin (HE) staining to observe the morphological changes and for immunohistochemical staining to observe the positive expressions of Ki67 and vimentin and to count the number of positive cells. Data were statistically analyzed with paired samples t test and Bonferronni correction. Results: In 2, 3, and 4 weeks post operation, the wound healing rates in hUCMSC+gel group were (80±11)%, (84±12)%, and (92±9)%, respectively, which were significantly higher than (67±18)%, (74±21)%, and (84±16)% in gel only group (with t values of 4.01, 3.52, and 3.66, respectively, P<0.05). The wound healing time in hUCMSC+gel group was (31±11) d, which was significantly shorter than (36±13) d in gel only group (t=-3.68, P<0.05). The microbiological culture of the postoperative wound secretion specimens from the adjacent wounds in 2 groups was identical, with negative results in 4 trial areas and positive results in 16 trial areas. In 3, 6, and 12 months post operation, the VSS scores of wounds in gel only group were 7.8±1.9, 6.7±2.1, and 5.4±1.6, which were significantly higher than 6.8±1.8, 5.6±1.6, and 4.0±1.4 in hUCMSC+gel group, respectively (with t values of -4.79, -4.37, and -5.47, respectively, P<0.05). In 3 months post operation, HE staining showed an increase in epidermal layer thickness and epidermal crest in wound in hUCMSC+gel group compared with those in gel only group, and immunohistochemical staining showed a significant increase in the number of Ki67 positive cells in wound in hUCMSC+gel group compared with those in gel only group (t=4.39, P<0.05), with no statistically significant difference in the number of vimentin positive cells in wound between the 2 groups (P>0.05). Conclusions: The application of hyaluronic acid gel containing hUCMSCs to the wound is simple to perform and is therefore a preferable route. Topical application of hUCMSCs can promote healing of the autologous Meek microskin grafted area in patients with extensive burns, shorten wound healing time, and alleviate scar hyperplasia. The above effects may be related to the increased epidermal thickness and epidermal crest, and active cell proliferation.

ABSTRACT

OBJECTIVE@#To assess the value of single sperm sequencing in preimplantation genetic testing for monogenic disease (PGT-M).@*METHODS@#A Chinese couple with two children whom had died of Spinal muscular atrophy (SMA) and attended the Jiangxi Provincial Maternal and Child Health Care Hospital in June 2020 was selected as the subject. Eleven single sperm samples were isolated by mechanical immobilization and subjected to whole genome amplification. Real-time PCR and Sanger sequencing were used to detect the SMN1 variants in the single sperm samples. Genomic DNA of the wife, her parents and the husband, as well as one single sperm sample harboring the SMN1 variant and two single sperm samples without the variant were used for the linkage analysis. Targeted capture and high-throughput sequencing were carried out to test 100 single nucleotide polymorphisms distributed within 2 Mb up- and downstream the variant site. The haplotypes linked with the SMN1 variants were determined by linkage analysis. Blastocyst embryos were harvested after fertilizing by intracytoplasmic sperm injection. Cells from the trophoblasts of each embryo were biopsied and subjected to whole genome amplification and targeted capture and high-throughput sequencing to determine their carrier status. Chromosomal aneuploidy of wild-type embryos was excluded. An euploid embryo of high quality was transferred. Amniotic fluid sample was taken at 18 weeks of gestation to confirm the status of the fetus.@*RESULTS@#Genetic testing showed that the couple both had deletion of exons 7 ~ 8 of the SMN1 gene. The wife has inherited the deletion from her father, while the husband was de novo. The haplotypes of the husband were successfully constructed by single sperm sequencing. Preimplantation genetic testing has indicated that 5 embryos had harbored the heterozygous variant, 4 embryos were of the wild type, among which 3 were euploid. Prenatal diagnosis during the second trimester of pregnancy has confirmed that the fetus did not carry the deletion.@*CONCLUSION@#By single sperm sequencing and PGT-M, the birth of further affected child has been successfully avoided.
