Heterotopic pancreas (HP) refers to the presence of ectopic pancreatic tissue located outside of the normal pancreatic location without anatomical or vascular continuity with the pancreas. HP within the gallbladder (HPGB) was first described by Otschkin in 1916. It remains an exceedingly rare pathology with few reported cases. Here we describe a case of HPGB in a 42-year-old female following laparoscopic cholecystectomy for symptoms of biliary colic. She presented with epigastric pain, elevated levels in liver function tests, and gallbladder sludge on ultrasound. Her lipase and bilirubin levels were within normal limits. Histopathological assessment of the gallbladder identified mild chronic cholecystitis and pancreatic heterotopia adjacent to the cystic duct of the gallbladder with all three elements (ducts, acini, and endocrine islets) of the pancreas, consistent with type 1 based on the classification of Gaspar Fuentes et al.HPGB is often diagnosed incidentally during histopathological examination after cholecystectomy. Preoperative diagnosis is challenging due to its rarity. It is thought to be asymptomatic. Although the clinical significance of HPGB remains uncertain, it has been hypothesized that HPGB can cause acalculous cholecystitis and also have the potential for malignant transformation. Our case supports the theory that the exocrine function of an ectopic pancreatic tissue may contribute to chronic inflammation in the gallbladder. In conclusion, although HPGB is a rare finding with unclear clinical relevance, its potential for malignancy and association with cholecystitis warrant further investigation. Given its scarcity, most knowledge about HPGB comes from case reports and case series. This report adds to the existing literature.

Solar energy, which is essential for the origin and evolution of all life forms on Earth, can be objectively recorded through attributes such as climatic ambient temperature (CAT), ultraviolet radiation (UVR), and sunlight duration (SD). These attributes have specific geographical variations and may cause different adaptation traits. However, the adaptation profile of each attribute and the selective role of solar energy as a whole during human evolution remain elusive. Here, we performed a genome-wide adaptation study with respect to CAT, UVR, and SD using the Human Genome Diversity Project-Centre Etude Polymorphism Humain (HGDP-CEPH) panel data. We singled out CAT as the most important driving force with the highest number of adaptive loci (6 SNPs at the genome-wide 1 × 10-7 level;401 at the suggestive 1 × 10-5 level). Five of the six genome-wide significant adaptation SNPs were successfully replicated in an independent Chinese population (N = 1395). The corresponding 316 CAT adaptation genes were mostly involved in development and immunity. In addition, 265 (84％) genes were related to at least one genome-wide associationstudy (GWAS)-mapped human trait, being significantly enriched in anthropometric loci such as those associated with body mass index (x2;P<0.005), immunity, metabolic syndrome, and cancer (x2;P<0.05). For these adaptive SNPs, balancing selection was evident in Euro-Asians, whereas obvious positive and/or purifying selection was observed in Africans. Taken together, our study indicates that CAT is the most important attribute of solar energy that has driven genetic adaptation in development and immunity among global human populations. It also supports the non-neutral hypothesis for the origin of disease-predisposition alleles in common diseases.

Currently, there are increasing debates on the necessity of health instruments in Chinese medicine (CM) emerging in China. This study aims to reevaluate its status and values. Analyzing the causes, limits, advantages, and properties characters of health instruments in CM, it is found that weak fundamental research, incomplete self-awareness, and complicated social factors are the primary causes of debates. A comprehensive analysis showed health instruments in CM have health evaluation benefits to people from a dominant Chinese culture, meet the requirements of cultural background, and bring long-term value to Chinese instrument researches. However, its values and status should be treated differently depending on various subtypes. Although little theoretical and practical evidences proved that patients-reported health instruments in CM should be proposed independently, the doctors- and nurses-reported questionnaires are necessary. With this in mind, the study group proposes the 'Chinese cultural instruments (CCIs)' and 'health-related CCIs'. The latter one aims to evaluate the health status of people in a dominant Chinese culture. The CCIs theory represents Chinese instrument researches on a larger regional and higher level, and resolves the debates on instruments between CM and Western medicine in China. Health instruments in CM bring more scientific and social benefits for Chinese instrument researches. However, it does not include cultural demands, and lacks scientific significance. CCIs have all its virtues, and add solutions to the latter's theory bottleneck and scientific debates, thus bringing increased benefits to clinical assessment in complementary and alternative medicine researches.
