OBJECTIVES: To evaluate the efficacy of acupuncture in treating breast cancer-related lymphedema (BCRL) by using systematic review and Meta analysis method. METHODS: Searching CNKI, Wanfang Data Knowledge Service Platform, VIP Chinese Journal Service Platform, Chinese Biomedical Literature Database, PubMed, Cochrane Library, Embase and Web of Science, the randomized controlled trials (RCTs) literature of acupuncture for BCRL was collected from the establishment of the databases to October 1st, 2023. After data extraction and risk of bias evaluation of the included literature, Meta-analysis was performed using RevMan5.4 software. RESULTS: A total of 14 RCTs with 952 patients were included. The Meta-analysis results showed that compared with comprehensive decongestive therapy (CDT), CDT-associated methods and other interventions of the contro group, acupuncture was able to decrease the circumference of the proximal 10 cm to elbow crease (MD=-1.95, P=0.000 5), reduce the difference in arm circumference (MD=-1.30, P<0.000 01), and increase the effective index (MD=27.47, P<0.000 01；RR=1.23, P=0.000 5)；acupuncture improves the range of motion(ROM) scores of shoulder joint in four areas：anteflexion(SMD=0.47, P=0.04), posterior extension (SMD=0.87, P<0.000 01), abduction (SMD=0.48, P=0.03), and adduction (SMD=0.72, P=0.000 5)；acupuncture also could alleviate pain and improve visual analog scale (VAS) scores (MD=-1.15, P<0.000 01). No serious adverse reactions were reported in the literatures. CONCLUSIONS: Acupuncture can effectively improve the degree of limb edema and subjective symptoms in BCRL patients.

Are oil spills enhancing outbreaks of red tides in the Chinese coastal waters from 1973 to 2017?

Between 1973 and 2017, evidences of red tide outbreaks and oil spill accidents in the Chinese coastal waters were collected. Statistical analysis and multiple regression models were used to determine the relationship between the red tide and the oil spill. Major findings reveal that (1) the frequency of red tides positively correlates to the number of oil spills and the volume of oil spilled as well; (2) the higher percentage of small spills (< 7 tonnes) are more likely to enhance the outbreaks of red tides; (3) both EI Niño and storm events do not show any relationship with red tides; and (4) more severe oil spill with penalty recorded implies a higher possibility to trigger the red tide afterwards. Therefore, oil spill contingency management focusing on small oil spills and mitigating their spill effect by physical measures could be of benefit to decrease the frequency of red tides significantly. For example, it is suggested to carry out physical combat instead of chemical dispersants to remove the spilled small oil in the shallow coastal areas for reducing the outbreak risk of red tides after the oil spill.

Protocol development for real-time ship fuel sulfur content determination using drone based plume sniffing microsensor system.

Pollutants from navigation sector are key contributors to emission inventories of most coastal cities with heavy port activities. The use of high fuel sulfur content (FSC) bunker oil by ocean going vessels (OGVs) has been identified as a major source of sulfur dioxide (SO2). Government authorities all over the world, including Hong Kong government, have implemented air pollution control regulations to cap FSC of fuel used by OGVs to 0.5%, from the existing 3.5%, to reduce SO2 emissions. However, the lack of efficient screening tools to identify non-compliant OGVs has prevented effective enforcement. This study developed and evaluated an unmanned aerial vehicle (UAV)-borne lightweight (750 g) microsensor system (MSS), which is capable of measuring ship plume SO2, NO2, NO, CO2, CO, and particulate matter in real-time. Extensive experiments were conducted on the sensor system to evaluate its performance during laboratory and field operations. The effects of cross-sensitivity and meteorological conditions were studied and incorporated to account for the measurement conditions in dispersed ship plumes. The SO2 to CO2 concentration ratio-based FSC expression was formulated as per the 2016 European Union Directive and Regulations. Furthermore, the impact of plume dilution on the accuracy of FSC measurement was investigated at different stages using the MSS, with and without the UAV in both simulated conditions and real-world scenarios, maintaining a safe distance from the OGV exhaust stacks. The study demonstrates the robustness of using UAV-borne sensor system for ship emission sniffing and FSC determination. The results will assist in development of a technological framework for effective enforcement of ship emission control regulations.

Identification of kinship and occupant status in Mongolian noble burials of the Yuan Dynasty through a multidisciplinary approach.

The Yuan Dynasty (AD 1271-1368) was the first dynasty in Chinese history where a minority ethnic group (Mongols) ruled. Few cemeteries containing Mongolian nobles have been found owing to their tradition of keeping burial grounds secret and their lack of historical records. Archaeological excavations at the Shuzhuanglou site in the Hebei province of China led to the discovery of 13 skeletons in six separate tombs. The style of the artefacts and burials indicate the cemetery occupants were Mongol nobles. However, the origin, relationships and status of the chief occupant (M1m) are unclear. To shed light on the identity of the principal occupant and resolve the kin relationships between individuals, a multidisciplinary approach was adopted, combining archaeological information, stable isotope data and molecular genetic data. Analysis of autosomal, mitochondrial and Y-chromosomal DNA show that some of the occupants were related. The available evidence strongly suggests that the principal occupant may have been the Mongol noble Korguz. Our study demonstrates the power of a multidisciplinary approach in elucidating information about the inhabitants of ancient historical sites.
