Abstract
Background To compare qualitative and quantitative superb microvascular imaging (SMI) and determine the value of SMI in the diagnosis of thyroid nodules (TNs) ≤10 mm based on the Chinese Thyroid Imaging Reporting and Data System 4 (C-TIRADS 4). Methods From October 2020 to June 2022, 106 patients with 109 C-TIRADS 4 (C-TR4) TNs (81 malignant, 28 benign) at the Peking Union Medical College Hospital were included. Qualitative SMI reflected the vascular pattern of the TNs and quantitative SMI was recorded by the vascular index (VI) of the nodules. Results The VI was significantly higher in malignant nodules versus benign nodules both in the longitudinal (19.9±11.4 vs. 13.8±10.6, P=0.01) and transverse (20.2±12.1 vs. 11.3±8.7, P=0.001) sections. The area under the curve (AUC) of qualitative and quantitative SMI did not show a statistical difference in the longitudinal {0.657 [95% confidence interval (CI): 0.560-0.745] vs. 0.646 (95% CI: 0.549-0.735), P=0.79} and transverse [0.696 (95% CI: 0.600-0.780) vs. 0.725 (95% CI: 0.632-0.806), P=0.51] sections. Next, we combined qualitative and quantitative SMI to upgrade and downgrade the C-TIRADS classification. If a C-TR4B nodule had VIsum >12.2 or intra-nodular vascularity, the original C-TIRADS was upgraded to C-TR4C. If a C-TR4C or C-TR4B nodule manifested VIsum ≤12.2 and no intra-nodular vascularity, the original C-TIRADS was downgraded to C-TR4A. As a result, 18 C-TR4C nodules were downgraded to C-TR4A and 14 C-TR4B nodules were upgraded to C-TR4C. The new model of SMI + C-TIRADS showed high sensitivity (93.8%) and accuracy (79.8%). Conclusions There is no statistical difference between qualitative and quantitative SMI in the diagnosis of C-TR4 TNs. The combination of qualitative and quantitative SMI may have the potential to manage diagnosis of C-TR4 nodules.

Abstract
The family of Papilionidae (Lepidoptera: Papilionoidea) is a group of butterflies with high ecological and conservation value. The Hengduan Mountains (HMDs) in Southwest China is an important diversity centre for these butterflies. However, the spatial distribution pattern and the climate vulnerability of Papilionidae butterflies in the HDMs remain unknown to date. The lack of such knowledge has already become an obstacle in formulating effective butterfly conservation strategies. The present research compiled a 59-species dataset with 1938 occurrence points. The Maxent model was applied to analyse the spatial pattern of species richness in subfamilies Parnassiinae and Papilioninae, as well as to predict the response under the influence of climate change. The spatial pattern of both subfamilies in the HDMs has obvious elevation prevalence, with Parnassiinae concentrated in the subalpine to alpine areas (2500-5500 m) in western Sichuan, northwestern Yunnan and eastern Tibet, while Papilioninae is concentrated in the low- to medium-elevation areas (1500-3500 m) in the river valleys of western Yunnan and western Sichuan. Under the influence of climate change, both subfamilies would exhibit northward and upward range shifts. The majority of Parnassiinae species would experience drastic habitat contraction, resulting in lower species richness across the HDMs. In contrast, most Papilioninae species would experience habitat expansion, and the species richness would also increase significantly. The findings of this research should provide new insights and a clue for butterfly diversity and climatic vulnerability in southwestern China. Future conservation efforts should be focused on species with habitat contraction, narrow-ranged distribution and endemicity with both in situ and ex situ measures, especially in protected areas. Commercialised collecting targeting these species must also be regulated by future legislation.

Abstract
Oakleaf butterflies in the genus Kallima have a polymorphic wing phenotype, enabling these insects to masquerade as dead leaves. This iconic example of protective resemblance provides an interesting evolutionary paradigm that can be employed to study biodiversity. We integrated multi-omic data analyses and functional validation to infer the evolutionary history of Kallima species and investigate the genetic basis of their variable leaf wing patterns. We find that Kallima butterflies diversified in the eastern Himalayas and dispersed to East and Southeast Asia. Moreover, we find that leaf wing polymorphism is controlled by the wing patterning gene cortex, which has been maintained in Kallima by long-term balancing selection. Our results provide macroevolutionary and microevolutionary insights into a model species originating from a mountain ecosystem.

Abstract
The collection of caterpillar fungus accounts for 50–70% of the household income of thousands of Himalayan communities and has an estimated market value of $5–11 billion across Asia. However, Himalayan collectors are at multiple economic disadvantages compared with collectors on the Tibetan Plateau because their product is not legally recognized. Using a customized hybrid-enrichment probe set and market-grade caterpillar fungus (with samples up to 30 years old) from 94 production zones across Asia, we uncovered clear geography-based signatures of historical dispersal and significant isolation-by-distance among caterpillar fungus hosts. This high-throughput approach can readily distinguish samples from major production zones with definitive geographical resolution, especially for samples from the Himalayan region that form monophyletic clades in our analysis. Based on these results, we propose a two-step procedure to help local communities authenticate their produce and improve this multi-national trade-route without creating opportunities for illegal exports and other forms of economic exploitation. We argue that policymakers and conservation practitioners must encourage the fair trade of caterpillar fungus in addition to sustainable harvesting to support a trans-boundary conservation effort that is much needed for this natural commodity in the Himalayan region.

Abstract
The chestnut tiger butterfly, Parantica sita (Kollar) (Lepidoptera: Nymphalidae: Danainae), occurs in Asia, along the Himalayas, and into the Malayan region. Previous studies found three types of mitogenomes with substantial genetic divergence in samples from China. To clarify the level of differentiation within P. sita, we investigated both molecular data and morphological features in 429 individuals from China. Upon examination, mitochondrial cytochrome oxidase subunit I (COI) sequences showed three substantially diverged haplotype groups. Based on microsatellite genotypes, the samples divided into three clusters that were consistent with the COI haplotype groups. With that genetic data, we named three distinguishable P. sita lineages: PS-A, PS-B, and PS-C. We also found obvious morphological differences in wing color, male sex brand, and genitalia structures among the three lineages. According to the published structure of male genitalia, that of PS-A is identical to that of P. s. sita, and that of PS-B is identical to that of P. pedonga. Based on all the results, we tentatively propose dividing P. sita into three species: PS-A (the former P. s. sita) is the typical Parantica sita [Kollar, (1844)], mainly distributed in southwestern China; PS-C (the former P. s. niphonica) is elevated to full species as Parantica niphonica (Moore, 1883), distributed in Taiwan Island and Japan; and PS-B will be Parantica pedongaFujioka, 1970, mainly distributed in Tibet and western Sichuan. Divergence time estimates showed that PS-A separated from the PS-B + PS-C clade about 8.79 million years ago (Ma), when the Hengduan Mountains underwent an appreciable elevation increase, isolating the Tibet population from the others. PS-B and PS-C diverged about 4.87 Ma, in accord with the formation of Taiwan Island mountains. The founder effect may explain why PS-C’s genetic diversity is lower than that of the other clades.

Abstract
UNLABELLED Exogenous melatonin inhibited the senescence of preosteoblast cells in type 1 diabetic (T1D) mice and those cultured in high glucose (HG) by multiple regulations. Exogenous melatonin had a protective effect on diabetic osteoporosis, which may depend on the inhibition of senescence. INTRODUCTION Senescence is thought to play an important role in the pathophysiological mechanisms underlying diabetic bone loss. Increasing evidence has shown that melatonin exerts anti-senescence effects. In this study, we investigated whether melatonin can inhibit senescence and prevent diabetic bone loss. METHODS C57BL/6 mice received a single intraperitoneal injection of 160 mg/kg streptozotocin, followed by the oral administration of melatonin or vehicle for 2 months. Then, tissues were harvested and subsequently examined. MC3T3-E1 cells were cultured under HG conditions for 7 days and then treated with melatonin or not for 24 h. Sirt1-specific siRNAs and MT1- or MT2-specific shRNA plasmids were transfected into MC3T3-E1 cells for mechanistic study. RESULTS The total protein extracted from mouse femurs revealed that melatonin prevented senescence in T1D mice. The micro-CT results indicated that melatonin prevented bone loss in T1D mice. Cellular experiments indicated that melatonin administration prevented HG-induced senescence, whereas knockdown of the melatonin receptors MT1 or MT2 abolished these effects. Sirt1 expression was upregulated by melatonin administration but significantly reduced after MT1 or MT2 was knocked down. Knockdown of Sirt1 blocked the anti-senescence effects of melatonin. Additionally, melatonin promoted the expression of CDK2, CDK4, and CyclinD1, while knockdown of MT1 or MT2 abolished these effects. Furthermore, melatonin increased the expression of the polycomb repressive complex (PRC), but knockdown of MT1 or MT2 abolished these effects. Furthermore, melatonin increased the protein levels of Sirt1, PRC1/2 complex-, and cell cycle-related proteins. CONCLUSION This work shows that melatonin protects against T1D-induced bone loss, probably by inhibiting senescence. Targeting senescence in the investigation of diabetic osteoporosis may lead to novel discoveries.

Abstract
A new species of the genus Neopseustis Meyrick, 1909, Neopseustischentangensis S.Y. Huang & Chen sp. nov., which was confirmed by both morphological and molecular methods, is described from Xizang, China. This is currently the westernmost species in Asia of the primitive lepidopteran family Neopseustidae. The new species is externally reminiscent of N.moxiensis Chen & Owada, 2009; however, it can be easily distinguished from the latter by comparison of the male genitalia and is further distinguished by the large genetic distance in DNA barcodes (COI). The adult and genitalia of the new and similar species have been illustrated. Utilizing our new data, a new classification of the genus is provided, with its members subdivided into four species groups: the meyricki-group, the moxiensis-group, the bicornuta-group, and the chentangensis-group, which are supported by both molecular and morphological evidence. A checklist of the genus and a key to the species groups are also provided.

Abstract
Except for a few stick insects that are economically valuable, most species be considered to be forest pests, so it is extremely important to obtain plant host-use information of more stick insects. In this paper, the plant hosts of three species of stick insects were recorded for the first time. We also discovered these stick insects can feed upon the flowers or leaves of plants. Lopaphus unidentatus (Chen & He, 1995) (Phasmida: Lonchodidae) attacked Hypericum choisianum Wall. ex N. Robson, 1973 (Hypericaceae), Leurophasma dolichocercum Bi, 1995 (Phasmida: Aschiphasmatidae) attacked Antenoron filiforme (Thunb.) Roberty & Vautier, 1964 (Polygonaceae) and Megalophasma granulatum Bi, 1995 (Phasmida: Lonchodidae) attacked Debregeasia orientalis C. J. Chen, 1991 (Urticaceae). Finally, we were lucky enough to also obtain photographs of them mating and feeding.

Abstract
In this research, atractylenolide II (ATR II) on apoptosis, cell cycle cells via ER pathway in breast cancer (MDA-MB-231 and MCF-7) cells are assessed. The effect of ATR II on cell proliferation was detected by MTT assay. Additional flow cytometry, luciferase, the western blot were performed to detect the signaling pathway cytotoxicity of ATR II. We have also carried out autodock measurements to validate our results. Our findings showed ATR II could inhibit breast cancer cell growth by apoptosis mainly through G2/M-phase cell cycle arrest. Besides, the cytotoxicity of ATTR II on breast cancer was also correlated by the regulation of endrogen receptors and promising an anti-inflammatory activity via inhibiting NF-KB signaling pathways. Taking together, ATR II could be a potential anti-cancer drug for breast cancer.

Abstract
The use of acoustic attractants may have the potential to guide native migratory species towards safe passage. Flower fish Ptychobarbus kaznakovi, a short-distance migratory fish whose population is in decline in the past decades, was exposed to three acoustic stimuli (feeding sound, ambient riverine noise and the pure tone 1000 Hz) to examine the phonotaxic responses using playbacks approaches in a fibreglass tank. The results showed that the flower fish showed significantly greater positive phonotaxis and swam towards the sound sources significantly faster in response to the feeding sounds than to ambient riverine noise and the pure tone during the 5-min exposure. Distribution experiments were conducted to study the preference of flower fish to the three sounds stimuli. The results showed that the experimental fish in feeding sound trials spent significant more time in areas closer to the sound sources than that in the pure tone and the ambient riverine noise trials, respectively. This study indicates that the feeding sounds may serve as potential acoustic attractants to guide flower fish to safe passage routes.

Abstract
The Tibetan Plateau is the highest and one of the most demanding environments ever inhabited by humans. We investigated the timing and mechanisms of its initial colonization at the Nwya Devu site, located nearly 4600 meters above sea level. This site, dating from 40,000 to 30,000 years ago, is the highest Paleolithic archaeological site yet identified globally. Nwya Devu has yielded an abundant blade tool assemblage, indicating hitherto-unknown capacities for the survival of modern humans who camped in this environment. This site deepens the history of the peopling of the "roof of the world" and the antiquity of human high-altitude occupations more generally.

Abstract
AIM Nuclear factor-erythroid 2-related factor-2 (Nrf2) acts as a defense system in the development of nonalcoholic steatohepatitis (NASH). Curcumin is a phenolic compound with lipid regulatory, anti-oxidative, anti-inflammatory and anti-tumorigenic properties that is beneficial in defending against NASH and was recently proved to be an Nrf2 activator. The aim of this study was to evaluate whether Nrf2 activation could be involved in NASH mitigation by curcumin. METHODS Hepatic, metabolic, and inflammatory parameters, along with hepatic Nrf2 protein expression were explored in adult Sprague-Dawley rats developing high-fat-diet-induced NASH and submitted to curcumin gavage for 6 weeks. RESULTS Curcumin administration led to lower degrees of hepatic steatosis and inflammation; lower levels of serum aminotransferases, lipids, and homeostasis model assessment of insulin resistance; and lower serum and hepatic contents of tumor necrosis factor-α (TNF-α), interleukin-6, and malondialdehyde. In contrast, higher hepatic contents of glutathione, heme oxygenase-1 and superoxide dismutase were observed in rats with curcumin. Moreover, Nrf2 expression in liver cell nuclei was significantly higher in rats with curcumin. CONCLUSIONS Curcumin can prevent and ameliorate NASH via lipid reduction, improve insulin resistance, improve anti-inflammatory, and have antioxidant effects, possibly related to its activation of Nrf2.

Abstract
Japanese encephalitis (JE) is a global public health issue that has spread widely to more than 20 countries in Asia and has extended its geographic range to the south Pacific region including Australia. JE has become the most important cause of viral encephalitis in the world. Japanese encephalitis viruses (JEV) are divided into five genotypes, based on the nucleotide sequence of the envelope (E) gene. The Muar strain, isolated from patient in Malaya in 1952, is the sole example of genotype V JEV. Here, the XZ0934 strain of JEV was isolated from Culex tritaeniorhynchus, collected in China. The complete nucleotide and amino acid sequence of XZ0934 strain have been determined. The nucleotide divergence ranged from 20.3% to 21.4% and amino acid divergence ranged from 8.4% to 10.0% when compared with the 62 known JEV isolates that belong to genotype I–IV. It reveals low similarity between XZ0934 and genotype I–IV JEVs. Phylogenetic analysis using both complete genome and structural gene nucleotide sequences demonstrates that XZ0934 belongs to genotype V. This, in turn, suggests that genotype V JEV is emerging in JEV endemic areas. Thus, increased surveillance and diagnosis of viral encephalitis caused by genotype V JEV is an issue of great concern to nations in which JEV is endemic. Japanese encephalitis virus (JEV) is a mosquito-borne virus that causes Japanese encephalitis (JE) with significant morbidity and mortality. Five genotypes (genotype I–V) have been identified based on the nucleotide sequence of viral envelope (E) gene of JEV. To date, the only known strain of genotype V is Muar strain, isolated from patient in Malaya in 1952. Since then, no genotype V JEV has been detected in the world. In this study, the JEV strain, XZ0934, was isolated from mosquito samples collected in China in 2009. The full-length genome sequences of the XZ0934 strain was determined and founded to be the second strain of genotype V JEV based on the phylogenetic analysis using the complete genome and structural gene sequences. This suggests that genotype V JEV is re-emerging after 57 years (1952–2009). Therefore, increased surveillance and more effective diagnosis for cases of JE caused by genotype V JEV are needed.

Abstract
OBJECTIVE To discuss the strategy of treatment of critically ill influenza A H1N1 patients in plateau region. METHODS Four seriously ill and 4 critically ill patients suffering from influenza A H1N1 were admitted to the intensive care unit during October 10th through December 19th 2009. They were treated with antivirus drug, antibiotics, corticosteroid, measures to enhance immune function, fluid and electrolyte supplementation, symptomatic treatment, and mechanical ventilation. With their clinical data the distinguishing features in the treatment of these patients were analyzed. RESULTS Oseltamivir as an antivirus drug, and moxifloxacin together with ceftriaxone or cefoperazone were given to all the patients. Fluid replacement was controlled to avoid over hydration. Corticosteroid was administered to 3 seriously ill patients and 3 critically ill patients. Methylprednisolone was given to 1 critically ill patient. gamma-globulin was given to 7 patients. Four patients underwent atraumatic mechanical ventilation with bi-level positive airway pressure (BiPAP) or continuous positive airway pressure (CPAP) with good result. Owing to deterioration in respiratory function, traumatic mechanical ventilation was instituted in a critically ill patient, primarily with synchronized intermittent mandatory ventilation (SIMV)+pressure support ventilation (PSV)+high positive end expiratory pressure (PEEP). The condition of the patient was improved, and ventilation modality was changed to spontaneous respiration+PSV+low PEEP before weaning. Finally the patient was weaned from respirator successfully. All the 8 patients survived and discharged from the hospital. CONCLUSION Short term, full dosage of corticosteroid should be given to seriously ill and critically ill influenza A H1N1 patients according to specification, and atraumatic mechanical ventilation should be installed early in the treatment.

Abstract
OBJECTIVE To estimate the prevalence of blindness among older adults aged >/= 40 years in Linzhou county, Lasa, China. METHODS Cluster sampling was used in randomly selecting individuals aged >/= 40 years in 44 villages in Linzhou county in May, 2000. A total of 3 153 individuals were examined for visual acuity and eye condition. The prevalence of blindness was calculated according to the pinhole vision with WHO blindness criterion (criterion A) and presenting vision with blindness criterion (criterion B). RESULTS The individuals examined were enumerated. The response rate was 97.4% (3 071/3 153). When the bilateral pinhole vision < 3/60 was defined as the blindness criterion, the prevalence of blindness was 2.3% [95% confidence interval (CI), 1.8 - 2.8]. The blindness prevalence was increased with age (P < 0.001). Men had a higher prevalence of blindness than women (P > 0.05). After adjusting for age, the difference had statistical significance (P < 0.05). Prevalence of blindness was higher among the illiterate persons than among those with 1 or more years of schooling (P < 0.001). But after adjusting for age, the difference had no statistical significance (P > 0.05). When the bilateral presenting vision < 6/60 was defined as the blindness criterion, the prevalence of blindness was 3.2% (95% CI, 2.6 - 3.8). The blindness prevalence was increased with age (P < 0.001). Men had a higher prevalence of blindness than women. The crude male-to-female odds ratio for moderate and severe blindness was 1.17 (P > 0.05). After adjusting for age, the difference had no significance too (P > 0.05). Prevalence of blindness was higher among the illiterate persons than among those with 1 or more years of schooling (P < 0.001). But after adjusting for age, the difference had no statistical significance (P > 0.05). CONCLUSIONS The prevalence of blindness is higher in the area of plateau. The principal cause of blindness is cataract.

Abstract
OBJECTIVE Two kinds of murine interleukin-12 (mIL-12) fusion gene vaccines were used to treat the murine low-load malignant T cell lymphoma EL4 as minimal residual disease (MRD) model. METHODS C57BL/6 synergistical mice were subcutaneously inoculated with 1 x 10(6) wild-type (wt) EL4 tumor cells as low-load lymphoma model treated with two mIL-12 gene vaccines. Package cell line PA317/12 producing mIL-12 retrovirus (RV) was used as in vivo vaccine and EL4 tumor cells transferred with mIL-12 gene as ex vivo vaccine. RESULTS In both mIL-12 gene vaccine-treated groups, there was no tumor growth in 50% mice 60 days after inoculation. Nine of these no tumor growth mice were re-challenged with 5 x 10(5) wt EL4 cells, and 5 of them survived without tumors in another 60 days. All control mice died with tumors within one month after inoculation. Among those developed tumors in both vaccine-treated groups, the development of tumors was delayed, the survival period prolonged (P < 0.01), and the tumors size at death smaller (P < 0.05) as compared with the controls. In the long-survived vaccine-treated mice, no residual tumor cells were found by morphological examination. CONCLUSION Both IL-12 gene vaccines can efficiently eliminate wt EL4 MRD in C57BL/6 mice.

Abstract
OBJECTIVE To construct retroviral vector carrying rapidly selective marker. METHODS The recombination retroviral vector GCGFPPXSN was constructed by cloning the green fluorescent protein (GFP) cDNA into the retroviral vector containing putative internal ribosome entry sites GCXPXSN and transferred in ecotropic packaging cell line PE501 by electroporation method. The supernatants of the PE501GCGFPPXSN were used to infect the amphotropic packaging cell line PA317. The G418 resistant clones were selected in 4 weeks and were detectable by fluorescence microscopy or by fluorescence-activated cell sorting(FACS). RESULTS A recombination retroviral vector GCGFPPXSN carrying rapidly selective marker GFP was constructed. GFP expression in packaging cell line PA317-GCGFPPXSN transferred by GCGFPPXSN was detected by fluorescence microscopy of FACS. PA317-GCGFPPXSN grew to a titer of 1.2 x 10(5) cpu/ml. By cocultivating retroviral vector producing cells and T lymphocytes, expression of GFP was observed in T lymphocytes 2 days after the end of the cocultivation. T lymphocytes expressing GFP were separated. CONCLUSION The mammalian cell can be efficient gene transfected by retroviral vector carrying GFP. The use of GFP for cell marking represents an important advantage over conventional strategies which typically involve the use of neomycin resistance. GFP, in fact, allows a rapid in vitro selection of transduced cell by FACS. The selection requires only two-day culture with this retroviral vector, compared with 10-14 day culture with a classical retroviral vector.

Abstract
The clinical features of 6 cases with severe veno-occlusive disease (SVOD) in 43 patients who received hemopoetic stem cell transplantation (HSCT) in our institute from May 1983 to March 1994 were reported. The incidence of SVOD was 14% of the 43 patients, and 7.9% of those received autologous bone marrow transplantation (ABMT), SVOD occurred within 3 weeks after HSCT in all the 6 cases and was manifested by painful hepatomegaly, jaundice, hyperbilirubinemia, increase of serum liver enzyme level and ascites. Although supportive and symptomatic treatment including steroids were given, all patients died of progressive multiorgan failure within 4 weeks after HSCT. It is suggested that SVOD of the liver is a major and often lethal complication of HSCT and prophylaxis of this disorder with anticoagulant and antiplatelet agents is essential in clinical HSCT.
