Association of Globodera rostochiensis (Nematoda) with Stunted and Chlorotic Potato Plants in Yunnan and Sichuan Provinces in China.

On a global basis, potato cyst nematodes (Globodera spp. Skarbilovich 1959 [Behrens 1975]) are one of the most serious soilborne pathogens in potato (Solanum tuberosum L.) production. In 2019 to 2020, 188 soil samples were taken from rhizosphere soil associated with the roots of stunted and chlorotic potato plants in the main potato-growing areas of Yunnan and Sichuan Provinces of China. Globodera rostochiensis Wollenweber 1923 (Skarbilovich 1959) was recovered from 112 of the samples. Nematode identification was as confirmed by morphometric, light microscopy, electron microscopy, and molecular methodologies. Population densities of G. rostochiensis ranged from 47.0 to 69.0 eggs/g of soil. A BLASTn homology search program was used to compare the sequences of populations of G. rostrochienses from Yunnan and Sichuan Provinces with populations of other Heteroderinae spp. and populations of G. rostochiensis from other nations. Although potato has been grown in China for at least 400 years and the nation produces more potato than any other country, potato cyst nematodes were not reported in China until 2022.

Automated evaluation of tumor spheroid behavior in 3D culture using deep learning-based recognition.

Three-dimensional in vitro tumor models provide more physiologically relevant responses to drugs than 2D models, but the lack of proper evaluation indices and the laborious quantitation of tumor behavior in 3D have limited the use of 3D tumor models in large-scale preclinical drug screening. Here we propose two indices of 3D tumor invasiveness-the excess perimeter index (EPI) and the multiscale entropy index (MSEI)-and combine these indices with a new convolutional neural network-based algorithm for tumor spheroid boundary detection. This new algorithm for 3D tumor boundary detection and invasiveness analysis is more accurate than any other existing algorithms. We apply this spheroid monitoring and AI-based recognition technique ("SMART") to evaluating the invasiveness of tumor spheroids grown from tumor cell lines and from primary tumor cells in 3D culture.

[Randomized controlled clinical study on ginger-partitioned moxibustion for patients with cold-damp stagnation type primary dysmenorrhea].

OBJECTIVE: To observe the effect of ginger-partitioned moxibustion in the treatment of patients with primary dysmenorrhea (PD) of cold-damp stagnation type. METHODS: A total of 209 PD patients were randomized into moxibustion group (n=105) and control group (medication group, n=104). Patients of the former group were treated with ginger-partitioned moxibustion at Shenque (CV 8) and Guanyuan (CV 4), once daily for 3 days in the first menstrual cycle, and 3 days before menstruation and once daily for 6 days in the 2nd and 3rd menstrual cycles, and those of control group were asked to take Yueyueshu Granules (a Chinese herbal patent drug for relieving PD). Clinical symptom scores were assessed before and after the treatment. RESULTS: After the treatment, of the 105 and 104 cases in the moxibustion and control groups, the cured, markedly effective, effective and failed cases were 58 (55.24%) and 32 (30.77%), 37 (35.24%) and 33 (31.73%), 5 (4.76%) and 24 (23.08%), and 5 (4.76%) and 15 (14.42%), respectively. The total therapeutic effect of moxibustion group wassignificantly better than that of control group (P<0.01). The effects of moxibustion for relieving mild, moderate and severe dysmenorrhea were evidently superior to those of medication (P<0.01). The symptom scores after the treatment and 3 months of post-treatment in moxibustion group were significantly lower than those of control group (P<0.01). CONCLUSION: Ginger-partitioned moxibustion therapy was effective for PD of cold-damp stagnation type.

[Effects of substance-partitioned moxibustion on plasma beta-EP content in the patient with primary dysmenorrhea of cold-damp stagnation type in the menstrual period].

OBJECTIVE: To probe into the mechanism of substance-partitioned moxibustion in treatment of primary dysmenorrhea (PD) of cold-damp stagnation type. METHODS: The treatment group (105 cases of PD) were treated with substance-partitioned moxibustion and the control group (104 cases) were treated with Chinese drug Yueyue-shu. Their therapeutic effects were observed. Plasma beta-endorphin contents in menstrual period were determined before and after treatment in 40 patients of each group. RESULTS: The total effective rate of 95.2% in the substance partitioned moxibustion group was better than 85.6% in the control group (P < 0.05); after treatment, plasma beta-endorphin content significantly increased in the substance-partitioned moxibustion group (P < 0.01). CONCLUSION: Substance-partitioned moxibustion has obvious therapeutic effect on primary dysmenorrhea of cold-damp stagnation type, which is carried out possibly through regulating the plasma beta-endorphin content as one of the mechanisms.

[Influence of ginger-partitioned moxibustion on serum NO and plasma endothelin-1 contents in patients with primary dysmenorrhea of cold-damp stagnation type].

OBJECTIVE: To explore the mechanism of ginger-partitioned moxibustion in the treatment of cold-damp stagnation type primary dysmenorrhea (PD) patients. METHODS: A total of 209 PD outpatients of cold-damp stagnation type from 3 hospitals were randomized into moxibustion group (n = 105) who were treated with ginger-partitioned moxibustion, and control group (n = 104) who were asked to take Yueyue Shu Granules (an effective patent drug for PD). Ginger-partitioned moxibustion was applied to Shenque (CV 8) and Guanyuan (CV 4) from the menstrual onset on for the first course and 3 days before the onset for the second and third course, continuously for 3 days. Before and after the treatment, plasma endothelin-1 (ET-1) and serum nitric oxide (NO) contents in those patients (n = 40/group) and normal women (n = 20) experiencing menstrual period were determined by radioimmunoassay and nitrate reductase method. RESULTS: After the treatment, of the 105 and 104 cases in moxibustion and control groups, 58 and 32 cured, 37 and 33 markedly effective, 5 and 24 effective, 5 and 15 failed, with the effective rates being 95.24% and 85.58% respectively. The therapeutic effect of moxibustion group was significantly better than that of control group (P<0.05). Before treatment, in comparison with normal group, plasma ET-1 contents in both moxibustion and control groups were significantly higher (P<0.01), while serum NO contents in these two groups markedly lower (P<0.01). After the treatment, self-comparison of both moxibustion and control groups showed that plasma ET-1 decreased significantly and serum NO levels in increased considerably (P<0.05, P<0.01), and the therapeutic effect of moxibustion group was markedly superior than that of control group in lowering plasma ET-1 (P<0.01). CONCLUSION: Ginger-partitioned moxibustion is effective in relieving primary dysmenorrhea patients' abdominal pain, which may be closely associated with its actions in lowering plasma ET-1 level and raising serum NO contents.

[Effects of electroacupuncture of different frequencies on slimming effect in the rat of experimental obesity].

OBJECTIVE: To compare the slimming effects of electroacupuncture of different frequencies. METHODS: The rats were randomly divided into a control group, a model group, an acupuncture group I (30 Hz), and an acupuncture group II (100 Hz). Acupoints selected were "Housanli" (ST 36), "Sanyinjiao" (SP 6), "Guanyuan" (CV 4), "Zhongwan" (CV 12). The changes of Lee's index, fat weight around the left kidney and the volume of the fat cell, blood lipids, insulin and leptin before and after treatment were compared. RESULTS: Compared with the model group, Lee's index, fat weight around the left kidney and the volume of the fat cell, blood lipids significantly changed in the two acupuncture groups (P<0.01), with the acupuncture group II being more change than that of the acupuncture group I (P<0.05); and compared with the model group, the leptin level decreased in the two acupuncture group (P<0.01) and the serum insulin level decreased (P<0.05) , with no significant difference between the acupuncture group I and the acupuncture group II (P>0.05). CONCLUSION: Electroacupuncture of different frequencies has different effects on fat metabolism in fat rats, and electroacupuncture of 100 Hz has a better effect than 30 Hz on obesity.
