Sweet potato is an important food crop that can also be used as an industrial raw material. Sucrose is the main form of long-distance carbohydrate transport in plants, and sucrose transporter (SUT) regulates the transmembrane transport and distribution of sucrose during plant growth and metabolism. Moreover, SUT plays a key role in phloem mediated source-to-sink sucrose transport and physiological activities, supplying sucrose for the sink tissues. In this study, the full-length cDNA sequences of IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ were obtained by rapid amplification of cDNA ends (RACE) cloning according to the transcripts of the two SUT coding genes which were differentially expressed in sweet potato storage roots with different starch properties. Phylogenetic analysis was performed to clarify the classification of IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆. The subcellular localization of IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ was determined by transient expression in Nicotiana benthamiana. The function of IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ in sucrose and hexose absorption and transport was identified using yeast functional complementarity system. The expression pattern of IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ in sweet potato organs were analyzed by real-time fluorescence quantitative PCR (RT-qPCR). Arabidopsis plants heterologous expressing IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ genes were obtained using floral dip method. The differences in starch and sugar contents between transgenic and wild-type Arabidopsis were compared. The results showed IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ encoded SUT proteins with a length of 505 and 521 amino acids, respectively, and both proteins belonged to the SUT1 subfamily. IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ were located in the cell membrane and were able to transport sucrose, glucose and fructose in the yeast system. In addition, IbSUT₆₂₇₈₈ was also able to transport mannose. The expression of IbSUT₆₂₇₈₈ was higher in leaves, lateral branches and main stems, and the expression of IbSUT₈₁₆₁₆ was higher in lateral branches, stems and storage roots. After IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ were heterologously expressed in Arabidopsis, the plants grew normally, but the biomass increased. The heterologous expression of IbSUT₆₂₇₈₈ increased the soluble sugar content, leaf size and 1 000-seed weight of Arabidopsis plants. Heterologous expression of IbSUT₈₁₆₁₆ increased starch accumulation in leaves and root tips and 1 000-seed weight of seeds, but decreased soluble sugar content. The results obtained in this study showed that IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ might be important genes regulating sucrose and sugar content traits in sweet potato. They might carry out physiological functions on cell membrane, such as transmembrane transport of sucrose, sucrose into and out of sink tissue, as well as transport and unloading of sucrose into phloem. The changes in traits result from their heterologous expression in Arabidopsis indicates their potential in improving the yield of other plants or crops. The results obtained in this study provide important information for revealing the functions of IbSUT₆₂₇₈₈ and IbSUT₈₁₆₁₆ in starch and glucose metabolism and formation mechanism of important quality traits in sweet potato.

This study aimed to investigate the effects of Erxian Decoction(EXD)-containing serum on the proliferation and osteogenic differentiation of MC3T3-E1 cells under oxidative stress through BK channels. The oxidative stress model was induced in MC3T3-E1 cells by H_2O_2, and 3 mmol·L~(-1) tetraethylammonium(TEA) chloride was used to block the BK channels in MC3T3-E1 cells. MC3T3-E1 cells were divided into a control group, a model group, an EXD group, a TEA group, and a TEA+EXD group. After MC3T3-E1 cells were treated with corresponding drugs for 2 days, 700 μmol·L~(-1) H_2O_2 was added for treatment for another 2 hours. CCK-8 assay was used to detect cell proliferation activity. The alkaline phosphatase(ALP) assay kit was used to detect the ALP activity of cells. Western blot and real-time fluorescence-based quantitative PCR(RT-qPCR) were used to detect protein and mRNA expression, respectively. Alizarin red staining was used to detect the mineralization area of osteoblasts. The results showed that compared with the control group, the model group showed significantly blunted cell proliferation activity and ALP activity, reduced expression of BK channel α subunit(BKα), collagen Ⅰ(COL1), bone morphogenetic protein 2(BMP2), osteoprotegerin(OPG), and phosphorylated Akt, decreased mRNA expression levels of Runt-related transcription factor 2(RUNX2), BMP2, and OPG, and declining area of calcium nodules. EXD-containing serum could significantly potentiate the cell proliferation activity and ALP activity, up-regulate the protein expression of BKα, COL1, BMP2, OPG, and phosphorylated Akt, and forkhead box protein O1(FoxO1), promote the mRNA expression of RUNX2, BMP2, and OPG, and enlarge the area of calcium nodules. However, BK channel blockage by TEA reversed the effects of EXD-containing serum in promoting the protein expression of BKα, COL1, BMP2, OPG, and phosphorylated Akt and FoxO1, increasing the mRNA expression of RUNX2, BMP2, and OPG, and enlarging the area of calcium nodules. EXD-containing serum could improve the proliferation activity, osteogenic differentiation, and mineralization ability of MC3T3-E1 cells under oxidative stress, which might be related to the regulation of BK channels and downstream Akt/FoxO1 signaling pathway.

OBJECTIVE: To explore the clinical characteristics and genetic variants in a patient with adult ceroid lipofuscinosis neuronal type 7 (ACLN7). METHODS: A female patient diagnosed with ACLN7 in Henan Provincial People's Hospital in June 2021 was selected as the study subject. Clinical data, auxiliary examination and result of genetic testing were retrospectively analyzed. RESULTS: The patient, a 39-year-old female, has mainly presented progressive visual loss, epilepsy, cerebellar ataxia and mild cognitive decline. Neuroimaging analysis has revealed generalized brain atrophy, prominently cerebellum. Fundus photography has revealed retinitis pigmentosa. Ultrastructural skin examination has revealed granular lipofuscin deposits in the periglandular interstitial cells. Whole exome sequencing revealed that she has harbored compound heterozygous variants of the MSFD8 gene, namely c.1444C>T (p.R482*) and c.104G>A (p.R35Q). Among these, c.1444C>T (p.R482*) was a well established pathogenic variant, while c.104G>A (p.R35Q) was a missense variant unreported previously. Sanger sequencing confirmed that the daughter, son and elder brother of the proband have respectively carried heterozygous c.1444C>T (p.R482*), c.104G>A (p.R35Q), and c.104G>A (p.R35Q) variants of the same gene. The family has therefore fit with the autosomal recessive inheritance pattern of the CLN7. CONCLUSION Compared with previously reported cases, this patient has the latest onset of the disease with a non-lethal phenotype. Her clinical features have involved multiple systems. Cerebellar atrophy and fundus photography may be indicative of the diagnosis. The c.1444C>T (p.R482*) and c.104G>A (p.R35Q) compound heterozygous variants of the MFSD8 gene probably underlay the pathogenesis in this patient.

OBJECTIVES: Application of ultrashort wave (USW) to rats with cerebral ischemia and reperfusion injury could inhibit the decrease of expression of secretory pathway Ca²⁺-ATPase 1 (SPCA1), an important participant in Golgi stress, reduce the damage of Golgi apparatus and the apoptosis of neuronal cells, thereby alleviating cerebral ischemia-reperfusion injury. This study aims to investigate the effect of USW on oxygen-glucose deprivation/reperfusion (OGD/R) injury and the expression of SPCA1 at the cellular level. METHODS: N2a cells were randomly divided into a control (Con) group, an OGD/R group, and an USW group. The cells in the Con group were cultured without exposure to OGD. The cells in the OGD/R group were treated with OGD/R. The cells in the USW group were treated with USW after OGD/R. Cell morphology was observed under the inverted phase-contrast optical microscope, cell activity was detected by cell counting kit-8 (CCK-8), apoptosis was detected by flow cytometry, and SPCA1 expression was detected by Western blotting. RESULTS: Most of the cells in the Con group showed spindle shape with a clear outline and good adhesion. In the OGD/R group, cells were wrinkled, with blurred outline, poor adhesion, and lots of suspended dead cells appeared; compared with the OGD/R group, the cell morphology and adherence were improved, with clearer outlines and fewer dead cells in the USW group. Compared with the Con group, the OGD/R group showed decreased cell activity, increased apoptotic rate, and down-regulating SPCA1 expression with significant differences (all P<0.001); compared with the OGD/R group, the USW group showed increased cell activity, decreased apoptotic rate, and up-regulating SPCA1 expression with significant differences (P<0.01 or P<0.001). CONCLUSIONS USW alleviates the injury of cellular OGD/R, and its protective effect may be related to its up-regulation of SPCA1 expression.

Objective: To investigate the misdiagnosis of area postrema syndrome (APS) manifesting as intractable nausea, vomiting and hiccups in neuromyelitis optic spectrum disease (NMOSD) and reduce the risk of misdiagnosis. Methods: We retrospectively analyzed data from NMOSD patients attending the Department of Neurology at the First Medical Center of PLA General Hospital between January 2019 and July 2021. SPSS25.0 was then used to analyze the manifestations, misdiagnosis, and mistreatment of APS. Results: A total of 207 patients with NMOSD were included, including 21 males and 186 females. The mean age of onset was 39±15 years (range: 5-72 years). The proportion of patients who were positive for serum aquaporin 4 antibody was 82.6% (171/207). In total, 35.7% (74/207) of the NMOSD patients experienced APS during the disease course; of these patients, 70.3% (52/74) had APS as the first symptom and 29.7% (22/74) had APS as a secondary symptom. The misdiagnosis rates for these conditions were 90.4% (47/52) and 50.0% (11/22), respectively. As the first symptom, 19.2% (10/52) of patients during APS presented only with intractable nausea, vomiting and hiccups; 80.8% (42/52) of patients experienced other neurological symptoms. The Departments of Gastroenterology and General Medicine were the departments that most frequently made the first diagnosis of APS, accounting for 54.1% and 17.6% of patients, respectively. The most common misdiagnoses related to diseases of the digestive system and the median duration of misdiagnosis was 37 days. Conclusions: APS is a common symptom of NMOSD and is associated with a high rate of misdiagnosis. Other concomitant symptoms often occur with APS. Gaining an increased awareness of this disease/syndrome, obtaining a detailed patient history, and performing physical examinations are essential if we are to reduce and avoid misdiagnosis.

OBJECTIVE: To explore the regulatory mechanism of human hepatocyte apoptosis induced by lysosomal membrane protein Sidt2 knockout. METHODS: The Sidt2 knockout (Sidt2^-/-) cell model was constructed in human hepatocyte HL7702 cells using Crispr-Cas9 technology.The protein levels of Sidt2 and key autophagy proteins LC3-II/I and P62 in the cell model were detected using Western blotting, and the formation of autophagosomes was observed with MDC staining.EdU incorporation assay and flow cytometry were performed to observe the effect of Sidt2 knockout on cell proliferation and apoptosis.The effect of chloroquine at the saturating concentration on autophagic flux, proliferation and apoptosis of Sidt2 knockout cells were observed. RESULTS: Sidt2^-/- HL7702 cells were successfully constructed.Sidt2 knockout significantly inhibited the proliferation and increased apoptosis of the cells, causing also increased protein expressions of LC3-II/I and P62(P < 0.05) and increased number of autophagosomes.Autophagy of the cells reached a saturated state following treatment with 50 μmol/L chloroquine, and at this concentration, chloroquine significantly increased the expressions of LC3B and P62 in Sidt2^-/- HL7702 cells. CONCLUSION Sidt2 gene knockout causes dysregulation of the autophagy pathway and induces apoptosis of HL7702 cells, and the latter effect is not mediated by inhibiting the autophagy-lysosomal pathway.

To summarize the clinical diagnosis and treatment process and genetic test results and characteristics of one child with Angelman syndrome (AS) complicated with oculocutaneous albinism type 2 (OCA2), and to review the literature. "Angelman syndrome" "P gene" and "Oculocutaneous albinism type 2" were used as keywords to search at CNKI, Wanfang, and PubMed databases (from creation to December 2019). Then all the patients were analyzed. The patient in this study was a girl aged 1 year. After birth, she was found to present as white body, yellow hair, and nystagmus. She could raise her head at the age of 2 months and turn over at the age of 7 months. The head circumference was 42 cm and she could not sit alone or speak at present. Trio-based exome sequencing revealed that the patient carried a homozygous mutation of c.168del (p.Gln58ArgfsTer44) in the P gene, and her father was heterozygous and her mother was wild-type. The detection of copy number variation showed deletion on the maternal chromosome at 15q11.2-13.1 region (P gene located in this region) in the patient. Until December 2019, a total of 4 cases in the 4 literature had been reported. Adding our case here, the 5 cases were summarized and found that all the cases showed white skin, golden hair, and shallow iris after birth. Comprehensive developmental delay was found around 6 months of age after birth, and the language remained undeveloped in 2 cases till follow-up into childhood. Seizures occurred in 4 patients. Two cases had ataxia. All the 5 cases had acquired microcephaly. Two cases had a family history of albinism. Electroencephalogram monitoring was completed in 3 cases and the results were abnormal. Genetic tests showed that all the 5 cases had deletion on maternal chromosome at 15q11-13 region. Four cases carried mutation of P gene on paternal chromosome. And 1 case was clinically diagnosed as OCA2 without P gene test. AS combined with OCA2 is relatively rare. OCA2 is easily diagnosed based on the obvious clinical manifestations after birth. When combined with clinical manifestations such as neurodevelopmental delay, it might indicate the possibility of AS that is hardly diagnosed clinically at an early stage. Genetic tests can reveal the cross-genetic phenomenon of AS and OCA2 and the complex of them can be eventually diagnosed.

OBJECTIVE: To explore the mechanisms of large-conductance calcium-activated potassium channel (BKCa) involved in inflammatory response in sepsis. METHODS: The serum levels of BKCa were measured by enzyme-linked immunosorbent assay (ELISA) in patients with sepsis (28 cases), patients with common infection (25 cases) and healthy people (25 cases). The relationship between levels of BKCa and acute physiology and chronic health evaluation II (APACHE II) were analyzed. Cultured RAW 264.7 cells were stimulated by lipopolysaccharide (LPS). In some experiments, a cell model of sepsis was constructed using Nigericin as the second stimulus signal. The mRNA and protein expressions of BKCa in RAW 264.7 cells stimulated with LPS (0, 50, 100, 1 000 μg/L) were measured by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blotting. RAW 264.7 cells were transfected with small interfering RNA of BKCa (siRNA-BKCa), and the levels of caspase-1 precursor (pro-caspase-1), interleukin-1β precursor (pro-IL-1β) in cell, and the levels of caspase-1 p20, IL-1β p17 of cell culture medium, and NOD-like receptor protein 3 (NLRP3), nuclear factor-κB (NF-κB) were measured by Western blotting. The apoptosis were detected by staining with propidium iodide (PI), the release rate of lactate dehydrogenase (LDH) were measured, and the expression of apoptotic protein Gasdermin D (GSDMD) was measured by Western blotting to evaluate the effect of silencing BKCa on cell pyrosis. RESULTS: The level of serum BKCa in patients with sepsis was significantly higher than that in patients with common infection and health peoples (ng/L: 165.2±25.9 vs. 102.5±25.9, 98.8±20.0, both P < 0.05). In addition, the level of serum BKCa in patients with sepsis was significantly positively correlated with APACHE II score (r = 0.453, P = 0.013). LPS could construct a sepsis cell model by which LPS could promote BKCa expression in mRNA and protein with a concentration-dependent manner. The mRNA and protein expressions of BKCa in the cells stimulated by 1 000 μg/L LPS were significantly higher than that in the blank group (0 μg/L) [BKCa mRNA (2^-ΔΔCt): 3.00±0.36 vs. 1.00±0.16, BKCa/β-actin: 1.30±0.16 vs. 0.37±0.09, both P < 0.05]. Compared with the control group, the ratios of caspase-1 p20/pro-caspase-1 and IL-1β p17/pro-IL-1β in the model group were significantly increased (caspase-1 p20/pro-caspase-1: 0.83±0.12 vs. 0.27±0.05, IL-1β p17/pro-IL-1β: 0.77±0.12 vs. 0.23±0.12, both P < 0.05), however, transfection of siRNA-BKCa induced the decrease both of them (caspase-1 p20/pro-capase-1: 0.23±0.12 vs. 0.83±0.12, IL-1β p17/pro-IL-1β: 0.13±0.05 vs. 0.77±0.12, both P < 0.05). Compared with the control group, the number of apoptotic cells, LDH release rate and GSDMD expression in the model group were significantly increased [LDH release rate: (30.60±8.40)% vs. (15.20±7.10)%, GSDMD-N/GSDMD-FL: 2.10±0.16 vs. 1.00±0.16, both P < 0.05], however, transfection of siRNA-BKCa induced the decrease both of them [LDH release rate: (15.60±7.30)% vs. (30.60±8.40)%, GSDMD-N/GSDMD-FL: 1.13±0.17 vs. 2.10±0.16, both P < 0.05]. The mRNA and protein expressions of NLRP3 in sepsis cells were significantly higher than those in the control group [NLRP3 mRNA (2^-ΔΔCt): 2.06±0.17 vs. 1.00±0.24, NLRP3/GAPDH: 0.46±0.05 vs. 0.15±0.04, both P < 0.05]. However, the expression of NLRP3 after siRNA-BKCa transfection was significantly lower than that in model group [NLRP3 mRNA (2^-ΔΔCt): 1.57±0.09 vs. 2.06±0.17, NLRP3/GAPDH: 0.19±0.02 vs. 0.46±0.05, both P < 0.05]. Compared with the control group, the NF-κB p65 nuclear transfer of sepsis cell were significantly increased (NF-κB p65/Histone: 0.73±0.12 vs. 0.23±0.09, P < 0.05). However, the NF-κB p65 expression in the nucleus were decreased after siRNA-BKCa transfection (NF-κB p65/Histone: 0.20±0.03 vs. 0.73±0.12, P < 0.05). CONCLUSIONS BKCa is involved in the pathogenesis of sepsis, and its possible mechanism is to activate NF-κB/NLRP3/caspase-1 signaling pathway to induce inflammatory factor production and cell death.

Renal interstitial fibrosis (RIF) is the crucial pathway in chronic kidney disease (CKD) leading to the end-stage renal failure. However, the underlying mechanism of Shen Qi Wan (SQW) on RIF is not fully understood. In the current study, we investigated the role of Aquaporin 1 (AQP1) in SQW on tubular epithelial-to-mesenchymal transition (EMT). A RIF mouse model induced by adenine and a TGF-β1-stimulated HK-2 cell model were etablished to explore the involvement of AQP 1 in the protective effect of SQW on EMT in vitro and in vivo. Subsequently, the molecular mechanism of SQW on EMT was explored in HK-2 cells with AQP1 knockdown. The results indicated that SQW alleviated kidney injury and renal collagen deposition in the kidneys of mice induced by adenine, increased the protein expression of E-cadherin and AQP1 expression, and decreased the expression of vimentin and α-smooth muscle actin (α-SMA). Similarly, treatmement with SQW-containing serum significantly halted EMT process in TGF-β1 stimulated HK-2 cells. The expression of snail and slug was significantly upregulated in HK-2 cells after knockdown of AQP1. AQP1 knockdown also increased the mRNA expression of vimentin and α-SMA, and decreased the expression of E-cadherin. The protein expression of vimentin increased, while the expression of E-cadherin and CK-18 significantly decreased after AQP1 knockdown in HK-2 cells. These results revealed that AQP1 knockdown promoted EMT. Furthermore, AQP1 knockdown abolished the protective effect of SQW-containing serum on EMT in HK-2 cells. In sum, SQW attentuates EMT process in RIF through upregulation of the expression of AQP1.

OBJECTIVE: To observe the effects on neural function, living ability and mental state of the patients with acute intracerebral hemorrhage (ICH), as well as aquaporin 4 (AQP4) in the serum after treated with electroacupuncture (EA) on the base of routine therapy of western medicine. METHODS: Seventy-two acute ICH patients were randomized into an observation group (36 cases, 4 cases dropped off) and a control group (36 cases, 2 cases dropped off). In the control group, the conventional treatment was delivered such as stopping bleeding, preventing re-hemorrhage, controlling blood pressure, mitigating neural edema and reducing intracranial pressure. In the observation group, on the base of the treatment in the control group, EA was supplemented. Acupoints included Shuigou (GV 26), bilateral Neiguan (PC 6) and Sanyinjiao (SP 6) etc. Electric stimulation was operated at Neiguan (PC 6) and Sanyinjiao (SP 6) on the same side, with disperse-dense wave, and 2 Hz/100 Hz in frequency, tolerable current intensity. Electric stimulation was delivered for 30 min in each treatment, once daily and for 6 times per week. The duration of treatment was 2 weeks in the two groups. Before and after treatment, changes of the scores of National Institutes of Health stroke scale (NIHSS), modified Barthel index (MBI) and mini-mental state examination (MMSE), as well as AQP4 content in the serum were observed in the two groups; the efficacy and safety were compared between the two groups. RESULTS: The NIHSS scores and the serum AQP4 content decreased after treatment when compared with those before treatment in the two groups (P<0.05), while, MBI and MMSE scores increased (P<0.05). In the observation group, NIHSS score and serum AQP4 content were lower than those of the control group (P<0.05), and MBI and MMSE scores were higher (P<0.05). The total effective rate of the observation group was 93.8% (30/32), higher than that of the control group (73.5%, 25/34, P<0.05). The treatment in the two groups was safe, without adverse reactions and events occurring in the patients. CONCLUSION Electroacupuncture, on the base of conventional treatment of western medicine, can effectively improve the neural function, living ability, mental state and serum AQP4 content of the patients with acute ICH. It is suggested that the effective treatment by electroacupuncture may be related to the regulation of the serum AQP4 content.
