Abstract
During the coronavirus disease 2019 (COVID-19) outbreak in Shanghai with the Omicron variant in March 2022, locally accessible hospitals and healthcare centres encountered difficulties quickly responding to a demand for hospitals that were rapidly increasing, optimizing clinical results and controlling the infection. In this commentary, we summarize the management strategies of patients in a temporary COVID-19 specialized hospital during the outbreak in Shanghai, China. The present commentary was considered eight characteristics of management system, including general idea, infection prevention team, and efficient time management, and preventive and protective measures management, strategies for the management of infected patients, disinfection management, drug supply management strategies, and medical waste management. Following eight characteristics, the temporary COVID-19 specialized hospital operated effectively for 21 days. A total of 9674 patients were admitted, 7127 cases (73.67%) were cured and discharged, and 36 were transferred to designate hospitals for better treatment. Twenty-five management staff, 1130 medical, nursing staff, 565 logistics staff, and 15 volunteers participated in the temporary COVID-19 specialized hospital, and no infection prevention team member was infected. We speculated that these management strategies could be potential references for public health emergencies.

Abstract
Objective: To compare the efficacy and safety of Tonghua Dongbao's insulin aspart injection (Rishulin) and NovoRapid (Novo Nordisk) in the treatment of diabetes. Methods: A 26-week, randomized, open-label, parallel-group, positive control drug and non-inferiority trial was conducted in 23 centers in China. A total of 563 diabetes with poor blood glucose control treated with insulin for at least 3 months before were included. The subjects were randomized(stratified block random method) into those receiving Rishulin or NovoRapid at a ratio of 3∶1. Both groups were combined with basal insulin (Lantus). The primary endpoint was the change in glycosylated hemoglobin (HbA1c) from baseline to the end of 24 weeks of treatment. Results: For full analysis set, after 24 weeks of treatment, HbA1c level of Ruishulin group decreased from (8.66±1.28)% to (7.77±1.09)% (P<0.001), and that of NovoRapid group decreased from (8.47±1.28) % to (7.65±0.97) % (P<0.001). Treatment difference in HbA1c (NovoRapid group-Ruishulin group) was -0.061% (95%CI -0.320-0.199). HbA1c<7.0% target reacing rates were 24.26% and 21.21% (P=0.456), and HbA1c<6.5% target reacing rates were 9.65% and 6.82% (P=0.310) in Ruishulin group and NovoRapid group, repectively. The standard 2 hours postprandial blood glucose (2hPG) in Ruishulin group decreased from (16.23±5.22) mmol/L to (12.65±4.57) mmol/L (P<0.001), and 2hPG in NovoRapid group decreased from (16.13±5.37) mmol/L to (11.91)±4.21) mmol/L (P<0.001). The fingertips blood glucose at 7-point of both groups exhibited varying degrees of reduction compared with those at baseline, repectively. Positive ratios of specific antibodies were 31.68% in Ruishulin group and 36.36% in NovoRapid group (P=0.320). Ratios of negative to positive were 7.43% and 10.61% (P=0.360), and ratios of positive to negative were 10.40% and 7.58% (P=0.360) in Ruishulin group and NovoRapid group, respectively. The incidence of hypoglycemia was 60.05% and 55.40% (P=0.371), and the incidence of adverse events was 76.60% and 77.70% (P=0.818) in Ruishulin group and NovoRapid group, respectively. Conclusions: Rishulin is not inferior to NovoRapid, and has shown good efficacy and safety. It can be an ideal choice for clinicians in patients with poor blood glucose control with insulin.

Abstract
The structure and performance of nuclear cytoplasmic autophagosomes was explored. Seventeen cases of hepatocellular carcinoma and liver cells with other diseases from liver tissues were selected. The nuclear cytoplasm were isolated and degraded by the nuclear membrane. Damaged cytoplasm had damaged its own membrane and the surrounding nuclear tissues other than the nuclear membrane, leading to specific nucleolysis and cell death of liver cancer cells and liver cells.

Abstract
Adiposis is reputed as a twin disease of type 2 diabetes and greatly harmful to human health. In order to understand the molecular mechanisms of adiposis, the changes of physiological, pathological, epigenetic and correlative gene expression were investigated during the adiposis development of C57BL/6J mice induced by long time (9 months) high-fat and high-sucrose diet (HFSD) sustainably. The results showed that mRNA transcription level of the Leptin, Glut4 and Glut2 genes have been obviously changed, which exhibit a negative correlation with methylation on their promoter DNA. The results also revealed that HFSD induced higher level of DNA methyltransferase 1 (DNMT1) in fat tissue might play important role in regulating the changes of methylation pattern on Glut4 and Leptin genes, and which might be one of the molecular mechanisms for the adiposis development.

Abstract
Objective: To explore short-term effect of intense pulsed light (IPL) combined with meibomian gland expression in treating meibomian gland dysfunction (MGD). Methods: This study was a prospective, randomized, double-masked, controlled study. Forty-four MGD patients were enrolled in the study and received three consecutive IPL treatments with an interval of 4 weeks. One eye of each patient was randomly assigned as the study eye receiving the IPL therapy with an energy of 14-16 J/cm(2), and the fellow eye was as the control eye receiving a placebo therapy with 0 J/cm(2). Meibomian gland expression was immediately performed after the IPL treatment in both eyes. Efficacy was evaluated through assessment of the meibomian gland yielding secretion score (MGYSS) , SPEED questionnaire, tear film break-up time (TBUT), cornea fluorescein staining and infrared meibography. Safety was evaluated through best spectacle corrected visual acuity, intraocular pressure, slit lamp examination and fundus examination. These examinations were performed before and after each treatment. Results: Significant improvements were observed in the MGYSS and TBUT after IPL treatments (P<0.05). The improvements compared to the baseline of MGYSS at the upper eyelid in the treatment eyes were significantly higher than those in the control eyes after the first treatment (Z=-2.036, P=0.003). The improvements compared to baseline of MGYSS at the lower eyelid and the TBUT in the treatment eyes were significantly higher than those in the control eyes after the second treatment (Z=-2.999 and -2.036, respectively P=0.007 and 0.042, respectively). SPEED and cornea fluorescein staining were decreased in both eyes after IPL treatments, but there was no statistical difference between the two eyes. No obvious complication was observed in the study. Conclusions: IPL treatment combined with meibomian gland expression is an efficient and safe therapy, and can increase meibomian gland yielding secretion, increase the TBUT, relieve the symptoms and repair the corneal epithelium defects for MGD eyes.

Abstract
Recent studies have revealed that the receptor activator of nuclear factor-kappa B ligand/RANK/osteoprotegerin (RANKL/RANK/OPG) system has an important role in vascular calcification, which is contributory to various cardiovascular diseases and intimately linked to the regulation of blood pressure. Therefore, we performed a case-control study to investigate the associations of 21 single-nucleotide polymorphisms (SNPs) in the TNFSF11, TNFRSF11A and TNFRSF11B genes in the RANKL/RANK/OPG system with hypertension and blood pressure in post-menopausal Chinese women. In this study, 503 hypertensive patients and 509 normal controls were recruited. Genotyping was performed using the high-throughput Sequenom genotyping platform. The results showed that two SNPs (rs6567270 and rs4603673) in the TNFRSF11A were associated with hypertension (P=0.010 and P=0.013, respectively) and systolic blood pressure (P=0.024 and P=0.023, respectively). One SNP (rs9646629) in the TNFRSF11A showed significant association with diastolic blood pressure (P=0.031). The results of this study suggest that TNFRSF11A but not TNFSF11 and TNFRSF11B genetic variation is associated with hypertension and blood pressure in Chinese women. The findings provide additional support for the genetic role of RANKL/RANK/OPG system in hypertension and blood pressure regulation.

Abstract
UNLABELLED Association between 22 single nucleotide polymorphisms (SNPs) in the TNFSF11, TNFRSF11A, and TNFRSF11B genes in the RANKL/RANK/OPG pathway with bone mineral density (BMD) in 881 post-menopausal women. Our results suggest that TNFSF11 and TNFRSF11A, but not TNFRSF11B, genetic polymorphisms influence BMD mainly in the femoral neck in post-menopausal Chinese women. INTRODUCTION The aim of this study was to assess the relationship of polymorphisms in the TNFSF11, TNFRSF11A, and TNFRSF11B genes in the RANKL/RANK/OPG pathway with bone mineral density (BMD) in a cohort of Chinese post-menopausal women. METHODS A cross-sectional study was conducted in 881 post-menopausal women aged 50-89 years. All participants underwent lumbar spinal (LS) and femoral neck (FN) BMD evaluation by dual-energy X-ray absorptiometry. Twenty-two TNFSF11, TNFRSF11A, and TNFRSF11B SNPs were genotyped. We tested whether a single SNP or a haplotype was associated with BMD variations. RESULTS Two SNPs in the TNFSF11 gene (rs2277439 and rs2324851) and one in the TNFRSF11A gene (rs7239261) were found to be significantly associated with FN BMD (p = 0.014, 0.013, and 0.047, respectively). Haplotype TGACGT of TNFSF11 rs9525641-rs2277439-rs2324851-rs2875459-rs2200287-rs9533166 was a genetic risk factor toward a lower FN BMD (beta = -0.1473; p = 0.01126). In contrary, haplotype TAGCGT of TNFSF11 rs9525641-rs2277439-rs2324851-rs2875459-rs2200287-rs9533166 was genetic protective factor for LS BMD (beta = 0.3923; p = 0.04917). CONCLUSIONS Our findings suggest that TNFSF11 and TNFRSF11A, but not TNFRSF11B, genetic polymorphisms influence BMD mainly in the femoral neck in post-menopausal Chinese women. This contributes to the understanding of the role of genetic variation in this pathway in determining bone health.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is a prevalent form of nonmelanoma skin cancer. Although numerous studies in white populations suggest that mutations in the TP53 gene play an important role in the development of BCC, it is not clear whether this is also the case in East Asian populations such as in China. AIM To investigate the frequency and the features of TP53 mutation in sporadic BCC in a Chinese population. METHODS In total, 30 patients with sporadic BCC, who had previously taken part in a study on PTCH1 mutations, were enrolled. BCC and control cells were obtained by laser-capture microdissection, and DNA was amplified and sequenced for analysis of TP53 mutations. RESULTS In the 30 BCC samples, 6 TP53 point mutations were found (frequency of 20%), and 4 of these 6 mutations had ultraviolet (UV)-specific alterations. Combining these results with those of the previous study on PTCH1 mutations, we found that two patients with had three types of genetic alterations (each had two PTCH1 mutations and one TP53 point mutation). A further two patients each had one PTCH1 mutation and one UV signature TP53 mutation. In addition, the total number of UV-specific mutations of PTCH1 and TP53 accounted for 20% of the total patient group. CONCLUSIONS The incidence of TP53 mutation in BCC in our Chinese subjects was lower than that reported for white populations. Many of the patients carried mutations of other genes in addition to of TP53. The majority of TP53 mutations were UV-induced specific alterations. However, the results of the two studies on TP53 and PTCH1 indicated that the incidence of UV-specific mutations is much lower in Chinese than in white populations.

Abstract
Drug-drug interactions (DDIs) may adversely affect the prevention and cure of diseases. The effects of three polyether ionophore antibiotics, salinomycin (SAL), monensin (MON), and maduramycin (MAD) on the pharmacokinetics of florfenicol (FFC) were investigated in broilers. The chickens were fed rations with or without SAL (60 mg/kg feeds), MON (120 mg/kg feeds), or MAD (5 mg/kg feeds) for 14 consecutive days. FFC was given to the chickens either intravenously (i.v.) or orally (p.o.) at a single dose of 30 mg/kg body weight. Blood samples were taken from each chicken at 0-24 h postadministration of FFC. The plasma concentration of FFC was detected by high-performance liquid chromatography. The plasma concentration of FFC decreased with i.v. or p.o. co-administration of SAL, MON, or MAD in broilers, implying occurrence of DDIs during the co-administration of FFC with these ionophores. Our findings suggest that more attention should be given to the use of FFC to treat bacterial infections in chickens supplemented with polyether ionophore antibiotics.

Abstract
BACKGROUND Alterations of the PTCH1 gene have been found to contribute to both familial and sporadic basal cell carcinoma (BCC), especially in Caucasian patients. Furthermore, the majority of PTCH1 gene mutations in sporadic BCCs in Caucasian patients carry ultraviolet (UV) signatures, suggesting the key role of UV light in BCC development. However, sporadic BCC in non-Caucasian population has a lower incidence, and the pathogenesis remains largely unknown. To date, there has been no mutation analysis on PTCH1 gene in Chinese patients with sporadic BCCs. OBJECTIVE To investigate genetic alterations of the PTCH1 gene in Chinese sporadic BCCs. METHODS Direct sequencing was used to screen for mutations in PTCH1 in 31 microdissected samples in Chinese sporadic BCCs. In addition, single nucleotide polymorphisms (SNPs) were studied for loss of heterozygosity (LOH). RESULTS Nineteen PTCH1 mutations in 17 of the 31 BCCs (54.8%) were identified. SNP analysis revealed LOH of PTCH1 in 10 of 23 BCCs (43.5%). Interestingly, the majority of mutations identified (63.2%) were insertion/deletion, which was different from the results in Caucasian cases whose mutations are predominantly point mutations. Only two (10.5%) of the remaining seven mutations were UV-specific C → T transition or tandem CC → TT transitions. All mutations occurred evenly throughout the entire PTCH1 protein domain without a hot-spot detected. CONCLUSION Mutations and LOH in PTCH1 were also highly prevalent in Chinese sporadic BCCs. However, UV light plays a less role in causing these mutations, suggesting other potential mechanisms in the development of sporadic BCC in Chinese patients.

Abstract
AIM Previous studies have shown that tenuigenin, a crude extract of Polygala tenuifolia Willd. that is commonly used in traditional Chinese herbal medicine for memory loss, can reduce the secretion of Abeta from cultured cells. However, the mechanism underlying this effect and the active compound derived from tenuigenin is unknown. In this study, a purified component of tenuigenin, tenuifolin, was examined and revealed to be an effective compound in vitro. METHODS Abeta secretion from three sets of COS-7 cells, each carrying a plasmid expressing a different form of APP was examined following the treatment with tenuifolin. Initially, tenuifolin was determined to have no inherent toxicity to either the transfected or wild type cells at the effective concentrations. Cells were then treated with 0.5-2.0 microg mL(-1) tenuifolin for 12 h and their media were examined via an ELISA for Abeta1-40 and Abeta-42. RESULTS We found that treatment with 2.0 microg mL(-1) tenuifolin significantly decreased Abeta secretion from COS-7 cells without altering the ratio of Abeta1-40 and Abeta-42. This effect is most probably due to inhibition of the beta-site APP cleaving enzyme as Abeta secretion was not inhibited from cells expressing the C99 fragment. CONCLUSION Tenuifolin is an effective compound from tenuigenin. We believe that this finding should lead the way for future experiments to determine the exact mechanism for tenuifolin's effect on Abeta secretion.

Abstract
BACKGROUND Autosomal recessive lamellar ichthyosis (LI) is a severe skin disorder characterized by generalized hyperkeratosis. Gene mutation in transglutaminase 1 (TGM1), which mediates cross-links in the formation of the cell envelope during terminal differentiation of epidermis, has been identified as a cause of LI. OBJECTIVES To determine mutations of TGM1 gene in three Chinese families with LI. METHODS The TGM1 gene was sequenced to identify disease-causing mutations in the three families with LI. One of the results was confirmed by using reverse transcriptase PCR and in situ hybridization. An in situ transglutaminase (TGase) 1 assay was performed to estimate TGase 1 activity in the patients' skin. RESULTS Four novel mutations of keratinocyte TGase1 (Q203X, D254N, R687H and IVS4 + 1G-->T) were found in the three families. No TGase 1 mRNA was detected in patient skin using RT-PCR and in situ hybridization, and the in situ TGase assay showed that there was no or decreased TGase 1 activity in patient skin. CONCLUSIONS Our findings suggest that four novel mutations in TGM1 gene result in decrease or absence of TGase activity in the skin and, as a consequence, cause the phenotype of LI.

Abstract
Netherton's syndrome is a rare autosomal recessive disorder caused by mutations of the SPINK5 gene, which encodes the lymphoepithelial Kazal-type-related inhibitor (LEKTI) protein. We observed microstructural changes and detected LEKTI activity and SPINK5 gene mutation in three Chinese patients with Netherton's syndrome. Decreased LEKTI activity was found in the skin of patients. Lamellar bodies and foci of electron-dense material were detected in the intercellular spaces of the stratum corneum. A novel homozygous splicing mutation of 1430+2 T-->G was found in the SPINK5 gene in one proband. No mutation was found in the other family.

Abstract
BACKGROUND Xeroderma pigmentosum (XP) is a group of autosomal recessive diseases characterized by hypersensitivity to ultraviolet rays. Among its eight complementation groups, XP group A (XPA) is the most severe type. The XPAC gene has been identified as the defective gene in XPA patients. OBJECTIVES To examine genomic DNA from a Chinese family with XPA, to determine the XPAC mutation and, after genetic counselling, to undertake DNA-based prenatal diagnosis in a subsequent pregnancy. METHODS Fetal DNA was extracted from amniotic fluid and used to amplify exon 5 of XPAC containing the potential mutation. Direct sequencing and restriction endonuclease digestion were used for prenatal diagnosis. RESULTS We identified a homozygous nonsense XPAC mutation of 631C-->T, which results in an R211X mutation in XPA protein, in the proband. Both her parents are heterozygous. Prenatal diagnosis demonstrated a heterozygous sequence predicting an unaffected child, and a healthy girl was born. CONCLUSIONS These data provide the first example of a DNA-based prenatal test for genodermatosis in China.

Abstract
AIM To compare the efficacy, safety and tolerability of adapalene gel 0.1% vs. tretinoingel 0.025% in a Chinese patient population. BACKGROUND Although acne vulgaris is a common problem among Asians and Asian-Americans, little has been published on the specific manifestations, sequelae, and treatment-responsiveness of this disorder in Asian skin types. Since Asian skin types tend to be more highly pigmented than those of white people of European descent, many Asians share the predisposition toward postinflammatory hyperpigmentation seen in Africans, African-Americans and other dark-skinned peoples. It is generally assumed that the efficacy and safety of topical retinoids is the same in Asians as in white people. Tretinoin has been available in China for decades; adapalene became available in 1998. METHODS A total of 150 patients with grade II-III acne vulgaris seen at three dermatology clinics were randomized to 8 weeks of daily treatment with either adapalene gel 0.1% or tretinoin gel 0.025%. Counts of total lesions, inflammatory lesions and non-inflammatory lesions were made at baseline and again at treatment weeks 2, 4, 6 and 8. Global assessment ratings, based on percent lesion reduction from baseline were also made. Erythema, burning, pruritus, scaling and dryness were rated on a 0-3 severity scale. RESULTS A total of 139 patients completed the efficacy evaluation, and 144 patients completed the safety evaluation. Both adapalene and tretinoin produce dramatic reductions in total, inflammatory and non-inflammatory lesion counts, in the range of 69-74% on average. More than 70% of patients in both groups had complete clearance or marked improvement. In general, irritation was mild, but was both more common and more severe in the tretinoin group vs. the adapalene group. No systemic side effects were seen. CONCLUSIONS Adapalene offers comparable efficacy to tretinoin, but is less irritating. It represents a good alternative for the treatment of mild to moderate acne vulgaris in Chinese patients.

Abstract
Acne vulgaris is a common dermatologic disease in Asian populations, as well as in Caucasians. Our objective was to evaluate the safety and efficacy of adapalene gel 0.1% in comparison with tretinoin gel 0.025% in Chinese patients with acne vulgaris. We used an 8-week, multicenter, randomized, controlled, investigator-masked, parallel group design study of adapalene gel 0.1% and tretinoin gel 0.025% in 150 Chinese patients with mild-to-moderate acne vulgaris. Our results showed that adapalene gel 0.1% had efficacy equivalent to tretinoin gel 0.025% against acne lesions in Chinese patients, with a more acceptable tolerability profile.

Abstract
Two kinds of autotrophic microalgae, Spirulina platensis (SP) and Chlorella protothecoides (CP) were pyrolyzed at the heating rates of 15, 40, 60 and 80 degrees C/min up to 800 degrees C in a thermogravimetric analyzer to investigate their pyrolytic characteristics. Three stages (dehydration, devolatilization and solid decomposition) appeared in the pyrolysis process. SP and CP mainly devolatilized at 190-560 degrees C and 150-540 degrees C, respectively. A total volatile yield of about 71% was achieved from each microalga. As the heating rate increased, a lateral shift to higher temperatures was observed in their thermograms, and the instantaneous maximum and average reaction rates in the devolatilization stage were increased while the activation energy was decreased. The value of activation energy for CP pyrolysis was 4.22-5.25 x 10(4), lower than that of SP (7.62-9.70 x 10(4)), and the char in final residue of CP was 14.00-15.14%, less than that of SP by 2-3%. This indicated that CP is preferable for pyrolysis over SP. The experimental results may provide useful data for the design of pyrolytic processing systems using planktonic microalgae as feedstock.

Abstract
High-speed counter-current chromatography (HSCCC) was applied to the separation and purification of phenylethanoid glycosides (PhGs) acteoside and 2'-acetylacteoside from Cistanches salsa (C.A. Mey) G. Beck with a quaternary two-phase solvent system composed of ethyl acetate-n-butanol-ethanol-water (4:0.6:0.6:5, v/v). HPLC analyses of the CCC fractions revealed that the two main PhGs were over 98% purity. Their chemical structures were identified by 1H NMR, 13C NMR and MS.

Abstract
OBJECTIVE In order to exploit the medicinal resources and provide a scientific evidence for the clinical use and quality of Cynomorium songaricum control, the chemical constituents and pharmacological effects of the stem of the plant were studied preliminarily. METHOD The chemical constituents were studied by spectral analysis and chemical method. The pharmacological effects were studied by an experiment on the defecation and deficiency of kidney function. RESULT AND CONCLUSION Seven compounds were isolated from the stem of C. songaricum and identified as beta-sitosterol(I), palmitic acid (II), ursloic acid (III), daucosterol (IV), (-)-catechin (VI), naringenin-4'-O-pyranogluoside (VII) and succinicyacid (XII). Compounds VI and XII were isolated from this species for the first time. The pharmacological results show that the different extracts facilitate catharsis and replenish the deficiency of kidney yang.

Abstract
Scleroderma is a fibrotic disease occurring in a localized or systemic form. The pathogenesis of scleroderma remains poorly understood. Recent studies revealed that various cytokines and growth factors were involved in the development of scleroderma fibrosis. Platelet-derived growth factor (PDGF) is a potent growth factor for mesenchymal cells, especially fibroblasts. It can promote fibroblasts proliferation, enhance extracellular matrix synthesis. It is also a chemoattractant to fibroblasts. To better understand the role of PDGF in pathogenesis of scleroderma, we performed both in vivo studies on the expression of PDGF beta-receptor protein in scleroderma tissue and in vitro studies on the expression of PDGF B-chain and PDGF beta-receptor mRNA in cultured fibroblasts derived from both lesions of scleroderma and normal skin. Immunohistochemistry staining showed that PDGF beta-receptor expression was greatly elevated in the dermis of scleroderma lesion whereas PDGF beta-receptor were expressed at low levels in normal skin. Northern blot analysis showed that cultured fibroblasts from scleroderma had higher expression of PDGF B-chain and PDGF beta-receptor mRNA than those from normal control. Two PDGF B-chain mRNA transcripts, 2.8 and 4.0 kb, were expressed. The 2.8 kb transcripts which had more efficient translation ability was the more predominantly expressed one. These results indicate that PDGF B-chain/PDGF beta-receptor signal pathway might be involved in the development of fibrosis in scleroderma, and that the 2.8 kb PDGF B-chain mRNA transcript may be the main modulation gene.
