This study compared the chemical profiles, component content, dry paste yield, and pharmacological effects of samples obtained from the mixed single decoctions and the combined decoction of Gegen Qinlian Decoction(GQD), aiming to provide an experimental foundation for evaluating the equivalence of the two decocting methods and the suitability of TCM formula granules in clinical application. The same decoction process was used to prepare the combined decoction and mixed single decoctions of GQD. Ultra-performance liquid chromatography coupled with Q-Exactive Orbitrap mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was employed to compare the chemical profiles between the two groups. High-performance liquid chromatography(HPLC) was used to compare the content of nine characteristic components between the two groups. Then, a delayed diarrhea mouse model induced by irinotecan was established to compare the pharmacological effects of the two groups on chemotherapy-induced diarrhea. The UPLC-Q-Exactive Orbitrap MS in ESI~+ and ESI~- modes identified 59 chemical components in the compound decoction and mixed single decoctions, which showed no obvious differences in component species. The content of baicalin and wogonoside was higher in the compound decoction, while that of puerarin, daidzein-8-C-apiosylglucoside, berberine, epiberberine, wogonin, glycyrrhizic acid, and daidzein was higher in the mixed single decoctions. Further statistical analysis revealed no significant difference in the content of the nine characteristic components between the compound decoction and the mixed single decoctions. The dry paste yield had no significant difference between the two groups. Compared with the model group, both compound decoction and mixed single decoctions alleviated the weight loss and reduced diarrhea index in mice. Both of them lowered the levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), cyclooxygenase-2(COX-2), intercellular adhesion molecule-1(ICAM-1), interleukin-10(IL-10), malondialdehyde(MDA), and nitric oxide(NO) in the colon tissue. Furthermore, they significantly increased the levels of glutathione peroxidase(GSH-Px) and superoxide dismutase(SOD). Hematoxylin-eosin(HE) staining showed that colon tissue cells were tightly arranged with clear nuclei in both groups without obvious difference. The compound decoction and mixed single decoctions showed no significant differences in chemical component species, content of nine characteristic components, dry paste yield, or the pharmacological effects on alleviating chemotherapy-induced diarrhea. The findings provide a reference for evaluating the flexibility and superiority of combined or single decocting method in the preparation of TCM decoctions or formula granules.

Poria(Fu Ling) is a bulk traditional Chinese medicine(TCM)with a long history and complex varieties. The royal medical records of the Qing Dynasty include multiple medicinal materials of Fu Ling, such as Bai Fu Ling(white Poria), Chi Fu Ling(rubra Poria), and Zhu Fu Ling(Poria processed with cinnabaris). The Palace Museum preserves 6 kinds of specimens including Fu Ling Ge(dried Poria), Bai Fu Ling, Chi Fu Ling, Zhu Fu Ling, Bai Fu Shen(white Poria cum Radix Pini), and Fu Shen Mu(Poria cum Radix Pini). After trait identification and textual research, we found that Fu Ling Ge was an intact sclerotium, which was processed into Fu Ling Pi(Poriae Cutis), Bai Fu Ling and other medicinal materials in the Palace. The Fu Ling in the Qing Dynasty Pa-lace was mainly from the tribute paid of the officials in Yunnan-Guizhou region. The tribute situation was stable in the whole Qing Dynasty, and changed in the late Qing Dynasty. The cultural relics of Fu Ling in the Qing Dynasty Palace confirm with the archival documents such as the royal medical records and herbal medicine books, providing precious historical materials for understanding Fu Ling in the Qing Dynasty and a basis for the restoration of the processing of the Fu Ling in the Qing Dynasty Palace.

The present study collected data on traditional Chinese medicine(TCM) compounds effective in relieving pain from the patent database of the State Intellectual Property Office(SIPO), sorted out the TCM compounds against pain in patents, and analyzed the medication rules to provide references for the research and development of new TCM drugs against pain. The data were subjected to frequency statistics, association rules, cluster analysis, and complex network analysis by IBM SPSS Modeler 18.3 and SPSS Statistical 26.0. The results showed that among the 101 oral prescriptions included in the statistics, the top 5 drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma, and among the 49 external prescriptions included in the statistics, the top 5 drugs were Myrrha, Olibanum, Angelicae Dahuricae Radix, Borneolum Syntheticum, and Chuanxiong Rhizoma. Whether oral or external prescriptions, the drugs were mainly warm in nature, and bitter, pungent, and sweet in flavor. According to TCM complex network analysis, the core drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, and Chuanxiong Rhizoma in oral prescriptions, and Olibanum, Myrrha, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, and Angelicae Sinensis Radix in external prescriptions. Overall, the therapeutic principles of oral prescriptions were mainly replenishing Qi, nourishing blood, and promoting Qi and blood circulation, while those of external prescriptions were activating blood, resolving stasis, promoting Qi flow, and relieving pain on the basis of the oral prescriptions. In the future research and development of TCM compounds against pain, the prescriptions should be modified with mind-tranquilizing and depression-relieving drugs. With the modernization of TCM, the development of new pain-relieving TCM compound patents based on ancient methods and clinical experience adhering to the guidance of TCM treatment based on syndrome differentiation can meet the new demand for pain treatment in the current society and give full play to the advantages of TCM in pain treatment.

Aims:
Oryctes rhinoceros beetle is one of the most damaging pests of oil palm and cause high oil palm mortality. The
empty fruit bunch mulch and rotten old trunk of oil palm in the field provide the organic matter for the breeding sites and
increases the number of O. rhinoceros larvae. Bacillus thuringiensis as bioinsecticide can synthesize crystal proteins
toxic to the larvae. The present study was aimed to find effective B. thuringiensis isolates as biopesticide against O.
rhinoceros larvae.
Methodology and results:
Screening process was carried out through heating of soil sample suspension at 80 °C to
eliminate the non-spore formers and plated onto T3 medium. Colony morphology was observed, followed by Gram and
endospore staining. The crystal protein was observed by Coomassie Brilliant Blue (CBB) staining. Bioassay test was
conducted by force-feed method followed by food contamination method. The results showed isolates SBB33 and
SBB35 were able to infect and caused high mortality to the O. rhinoceros larvae. Isolates SBB33 and SBB35 showed
the highest mortality against 1st instar larvae (94.44% and 75% respectively) and 3rd instar larvae (64.8% and 60%
respectively) compared to control treatments. The 16S rRNA gene sequencing showed SBB33 has high similarity with B.
thuringiensis strain 3S2-3, while SBB35 has high similarity with B. thuringiensis strain GCU_BTi10. Protein separation of
the spore-crystal mixture by SDS-PAGE showed the prominence of 66 kDa protein band that was predicted to be Cry
toxins which is specific to coleopterans insect.
Conclusion, significance and impact of study
Bacillus thuringiensis isolates SBB33 and SBB35 have high potential
as biopesticides against O. rhinoceros larvae and could be used to control major pests in oil palm plantation.

Objective To establish the basic data for estimating minimum postmortem interval (PMImin) of heavily decayed and skeletonized remains by studying the development of Dermestes maculatus DeGeer (Coleoptera: Dermestidae). Methods The developmental stages of Dermestes maculatus were observed at four constant temperatures of 20 ℃, 24 ℃, 28 ℃ and 32 ℃, and the changes in body length were also examined as the biological indicator to estimate larval day-age and instar. Results The total developmental time from egg to adult at 20 ℃, 24 ℃, 28 ℃ and 32 ℃ were (126.7±10.6) d, (69.4±8.2) d, (50.4±8.4) d and (49.6±6.5) d, respectively. The body length increased gradually, but changed irregularly as a whole. Conclusion The study provides basic data on the development and growth of Dermestes maculatus, especially on its developmental duration as a significant value for estimating PMImin of heavily decayed and skeletonized remains. Nevertheless, the change of body length is not found to be the best biological indicator for instar determination.

Colorado potato beetle is a most destructive insect pest of potato throughout the world. Although utilization of chemical insecticides is a main method for management of this pest, their negative side-effects such as threat to humans and the environmental pollution prompted researchers to search for natural alternatives. Recently plant essential oils with low or without side-effects against noun-targeted organisms and with high availability were considered as safe bio-pesticides. In the present study, toxicity of essential oil of Iranian lemongrass, Cymbopogon citratus Stapf, was evaluated against 3th instar larvae and adults of Colorado potato beetle by a leaf dipping method. Results displayed essential oil had notable toxicity against both larvae and adults after 24 and 48 h exposure times. Probit analysis revealed LC₅₀ values (lethal concentration to kill 50% of population) with 95% confidence limits were 10.32 (9.17 – 11.72) and 7.76 (6.80 – 8.74) µl/ml for larvae and 6.27 (4.82 – 8.15) and 4.35 (3.24 – 5.62) µl/ml for adults after 24 and 48 h, respectively. Based on regression analysis, a positive correlation between log concentration of essential oil and insect mortality was achieved. Results indicated C. citratus essential oil can be candidate as a natural alternative to the harmful chemical insecticides in the management of Colorado potato beetle.

In the bilateral axillo-breast approach (BABA), the camera is inserted through the areolar incision, and this raises the concern it might be difficult to identify the lymph nodes (LN). The purpose of this study is to evaluate the feasibility of the Firefly for central lymph node dissection (CLND) in robotic thyroidectomy using the BABA. This study evaluated 18 patients who underwent robotic surgery using Firefly between December 2015 and March 2016. For LN mapping, 0.05 ml of ICG was injected into the thyroid 3~4 minutes before CLND. Green-stained LN could be detected easily through a near-infrared camera. The number of retrieved LNs was 7.8±3.0 after CLND using the Firefly, which was higher than the 6.7±0.2 reported in previous surgeries. In addition, it helped to distinguish between the parathyroid and the LNs. The Firefly technology was helpful in identifying the LNs, guiding the CLND and performing a complete CLND.

The purpose of this study was to verify the validity of Mealworms as a hospital meal with increased nutrition density. We provided a meal for postoperative patients and conducted analysis of dietary intake and nutritional status of patients and assessment of acceptability of the meal. This study was carried out as a randomized control trial. Patients were supplied either a hospital meal using Mealworms (Experimental group) or a regular hospital meal (Control group). We investigated the administration amounts of parenteral nutrition (PN) and food intake of patients after surgery and measured anthropometry, body composition, and blood tests before surgery and at hospital discharge. We included 34 postoperative patients who were admitted to Gangnam Severance Hospital from March to September. In the groups of patients not supplied with PN, the experimental group (964.68±284.6 kcal, 38.82±12.9 g) had significantly higher dietary calorie and protein intake than the control group (666.62±153.7 kcal, 24.47±4.9 g)(P<0.05). Additionally in the group of patients not supplied with PN, the experimental group (1.37%) showed a significantly higher increase in fat free mass index than the control group (−3.46%)(P<0.05). In all subjects, calorie density and protein density were significantly higher in the experimental group (P<0.001), and acceptability of calorie (P=0.036) and protein (P=0.001) was also significantly higher in the experimental group. Therefore, the results of this study support the validity of the introduction of hospital meals using Mealworms.

OBJECTIVES: We surveyed the awareness and current status of using fumigant carbon disulfide for exterminate Curculio sikkimensis among chestnut farmers in Chungnam Province to suggest directions for health education and public relations. METHODS: We designed questionnaires to evaluate recognition of fumigant carbon disulfide. We conducted a questionnaire survey to assess recognition and recognition level of fumigant carbon disulfide by the study variables. RESULTS: The recognition status for fumigant carbon disulfide was 74.5%, but the recognition level was low (know well 27.5%). The path of recognition was 45.1% and 15.7% for neighbor and rural technology center, respectively. The recognition status for warning label of fumigant carbon disulfide was 52.9%. Recognition for warning label of fumigant carbon disulfide was tended to increase with high educational attainment, bigger owning land area. Recognition on the content of warning label were 29.4%, 27.5%, 21.6%, and 21.6% for inflammability, toxicity, hazard, and explosiveness, respectively. Using personal protection equipment was tended to increase with the high status of awareness on fumigant carbon disulfide. CONCLUSIONS: Health education programs for using fumigant carbon disulfide are needed for chestnut farmers. In addition, publicity information activities about prevention and protection of carbon disulfide poisoning are needed for high risk farmers.

Insect antifreeze protein (AFP) has high antifreeze activity. Antifreeze proteins can be used in cryopreservation of biological tissues and cells. We expressed an antifreeze protein from the desert beetle Microdera punctipennis in yeast and determined the function of the protein at low temperatures. Yeast expression vector, pPIC9K-Mpafp698, was constructed and transformed into Pichia pastoris GS115. The expression of MpAFP698 was induced by methanol, and identified by tricine SDS-PAGE and Western blotting. Mpafp698 gene was inserted into the genome of the host yeast strain GS115, and correctly expressed. Hardly any yeast's own protein was secreted into the media. Cryoprotective experiments showed that MpAFP698 can significantly protect mouse liver as well as other mouse organs from cold damage compared with those in the control of Bovine serum albumin (BSA) addition. Besides, the hemolysis of blood cells protected by MpAFP698 at 4 degrees C was reduced and the survival rate of SF9 cells protected by MpAFP698 after freezing and thawing was increased compared to those of the control with BSA addition. Our results showed that MpAFP698 can be expressed in yeast, which allows a convenient purification of the MpAFP protein that has the cryoprotective effect.
