Twenty—two cases were treated with 5 cases markedly effective,9 cases fairly effective.6 cases improved.2 cases ineffective.The efficacy was stable,with nountoward reactions upon follow—up exam.All theimmunologic indexes and marrow megakaryocyteswere markedly improved.

To investigate the effect of Yisui Jiedu Recipe (YSJDR), a compound traditional Chinese herbal medicine, on cytokines and their corresponding just another kinase 2-signal transducers and activators of transcription 5 (JAK2-STAT5) signal transduction pathway in bone marrow hematopoietic cells from patients with myelodysplastic syndrome-refractory anemia (MDS-RA).

OBJECTIVE: Adopting methods of cell culture to explore the effects and mechanisms of Jianpi Bushen Huoxue Prescription (JPBSHXP), a traditional Chinese compound herbal medicine for strengthening spleen, reinforcing kidney and activating blood circulation, in inhibiting hematopoietic cells apoptosis in a mouse model of aplastic anemia (AA). METHODS: Blood serum of AA mice was made from an AA mouse model. Blood serums containing different traditional Chinese compound herbal medicine were made from rats after intragastric administration of JPBSHXP and its related decoctions, respectively. Bone marrow cells of normal mice were incubated by these blood serums for 24 hours, respectively. The apoptosis of the bone marrow cells were assayed by flow cytometry and transmission electron microscopy (TEM). RESULTS: It was indicated that the bone marrow cells of normal mice incubated with blood serum of AA mice displayed typical apoptosis. The apoptosis rates of bone marrow cells of the AA mice incubated by blood serum containing different traditional Chinese herbal medicine were decreased. The effect of Bushen (reinforcing kidey) Recipe was better than Jianpi (strengthening spleen) Recipe and Huoxue (activating blood circulation) Recipe, while the effect of JPBSHXP was the best. TEM results showed that the effect of Bushen Recipe was better than that of the Jianpi Recipe and the Huoxue Recipe, while the effect of JPBSHXP was the best. CONCLUSION: JPBSHXP and its related decoctions can significantly decrease the apoptosis rate of bone marrow mononuclear cells of the AA mice. It is inferred that JPBSHXP can promote bone marrow hematogenesis.

Objective To observe the therapeutic effect of electronic moxibustion apparatus and stone needle for primary dysmenorrhea disease in 35 cases.Methods 70 patients were randomly divided into the treatment group of 35 cases by random number table ,using electronic moxibustion apparatus and stone needle for treatment;and con-trol group of 35 cases,only using electronic moxibustion apparatus for treatment from 5 days before menstruation ,the treatment was continuous for 5 days,a course including 3 menstruation cycles .The clinical therapeutic effect after one treatment course was observed .Results The curative effects of the two groups were respectively 91.42% and 88.57%(χ2 =0.16,P>0.05);recovery rates of the two groups were respectively 77.14%and 42.85%(χ2 =8.57, P<0.05).The scores of the VAS,CMSS of the treatment group were much lower than those of the control group after treatment (t=2.532,2.137,2.256,P<0.05).Conclusion Electronic moxibustion apparatus and stone needle therapy is an effective method to treat primary dysmenorrhea ,which is a safe and convenient method .

Objective:To explore the association between mild cognitive impairment(MCI)and the risk of all-cause death among community middle-aged and older adults, and to provide evidence for early identification of high-risk populations.Methods:From September to November 2011, the residents aged 55 years and middle-aged and older in five urban communities were selected as the research objects by typical sampling method.The baseline survey of general information questionnaire, Mini-Mental State Examination(MMSE), activity of daily Living Scale(ADL), Geriatric Depression Scale(SDS)was carried out and the physical examination was performed.Mild cognitive impairment at the time of enrollment was the exposure factor.In 2017, 2019 and 2021, Deaths were followed up through home visits and search for death surveillance information systems.COX regression model was used to analyze the influencing factors for death.Results:A total of 1046 participants completed the follow-up and were included in the study.The baseline age was(66.4±6.6)years, and 199(19.0%)of them met the criteria for MCI.The average follow-up time was 112±16 months.During the follow-up period, 106 deaths were observed.The mortality rate was higher in participants with MCI(40 deaths, 21.1%)than those without MCI [(66 deaths, 10.1%), χ2=26.80, P<0.001)]. Participants with MCI had a shorter median survival time than those without MCI[(108.0±1.5) vs.(113.0±0.5)months, χlog-rank2=28.02, P<0.001]using the Kaplan-Meier method.Controlling for gender, age, and ethnicity, the Cox regression model revealed that MCI is associated with an increased risk of all-cause death( HR=1.98, 95% CI: 1.30-3.02, P=0.023). Conclusions:Mild cognitive impairment is an independent risk factor for all-cause death among community older adults.Early identification and intervention of MCI may have potential value in preventing premature death and prolonging life in middle-aged and older adults.

The genomic diversity of Avian leukosis virus subgroup J (ALV-J) was investigated in an experimentally infected chicken. ALV-J variants in tissues from four different organs of the same bird were re-isolated in DF-1 cells, and their gp85 gene was amplified and cloned. Ten clones from each organ were sequenced and compared with the original inoculum strain, NX0101. The minimum homology of each organ ranged from 96.7 to 97.6%, and the lowest homology between organs was only 94.9%, which was much lower than the 99.1% homology of inoculum NX0101, indicating high diversity of ALV-J, even within the same bird. The gp85 mutations from the left kidney, which contained tumors, and the right kidney, which was tumor-free, had higher non-synonymous to synonymous mutation ratios than those in the tumor-bearing liver and lungs. Additionally, the mutational sites of gp85 gene in the kidney were similar, and they differed from those in the liver and lung, implying that organ- or tissue-specific selective pressure had a greater influence on the evolution of ALV-J diversity. These results suggest that more ALV-J clones from different organs and tissues should be sequenced and compared to better understand viral evolution and molecular epidemiology in the field.

Objective:To explore the cause of death of 2 suspected Yunnan sudden unexplained death (YNSUD) cases in Dayao County, Yunnan Province.Methods:The field epidemiological investigation and autopsy of 2 cases of YNSUD in Dayao County from June 15 to 20, 2020 were conducted; and blood and tissue samples were collected for qualitative analysis of common poisons and drugs.Results:The areas where the two cases were located were all seriously ill villages with a history of YNSUD, and the time of death occurred in the onset season of YNSUD. There was no blood relationship between the 2 cases, no obvious abnormal symptoms before death, no special diet, no history of exposure to pesticides and other toxic chemicals, and the test results of common poisons were all negative. Autopsy pathological examination results showed that case 1 died of acute cardiac dysfunction caused by sudden acute myocardial infarction of coronary heart disease, and case 2 died of central respiratory and circulatory failure caused by spontaneous subarachnoid hemorrhage.Conclusions:The two cases are excluded from YNSUD through autopsy, and the cause of death is determined. It is suggested that emergency response should be taken as soon as possible for YNSUD cases, and autopsy should be actively carried out to clarify the cause of death from a pathological point of view.

OBJECTIVETo compare the effects between acupuncture with regulating mind and spleen and wes-tern medication for diarrhea irritable bowel syndrome (IBS-D).

METHODSEighty-one patients were randomly at the ratio of 2 to 1 assigned into an acupuncture group (54 cases) and a western medication group (27 cases). Acupuncture with regulating mind and spleen was applied in the acupuncture group for 6 weeks at Baihui (GV 20), Yintang (GV 29), Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Sanyinjiao (SP 6), and Taichong (LR 3), once every other day, 3 times a week. Pinaverium bromide tablet was used orally in the western medication group for 6 weeks, 50 mg a time, 3 times a day. IBS symptom severity score (IBS-SSS) were observed before and after 1-week, 6-week treatment. Pittsburgh sleep quality index (PSQI) was applied before and after 6-week treatment. Also, clinical efficacy was evaluated in the two groups.

RESULTSThree patients dropped out in the acupuncture group, and 1 in the western medication group. Except abdominal distension score after 1-week treatment in the western medication group, single scores and total scores of IBS-SSS apparently reduced in the two groups after 1-week and 6-week treatment (<0.01,<0.05). After 1-week treatment, the abdominal pain score of the acupuncture group was obviously lower than that of the western medication group (<0.05). After 6-week treatment, with abdominal pain relief advantage, other results including the number of pain days, defecation satisfaction,life disturbance degree and total score of the acupuncture group were obviously lower than those of the wes-tern medication group (<0.01,<0.05). After 6-week treatment, the PSQI score and its change before and after treatment in the acupuncture group were superior to those in the western medication group (both<0.05). The relief rate and relief plus obvious effective rate in the acupuncture group were higher than those in the western medication group[51.0% (26/51) vs 19.2% (5/26),<0.01; 64.7% (33/51) vs 34.6% (9/26),<0.05].

CONCLUSIONSAcupuncture with regulating mind and spleen for diarrhea irritable bowel syndrome can more effectively relieve abdominal pain than pinaverium bromide tablet at the early stage. Its total effect and single effects are better at the later stage on abdominal pain, seizure frequency, defecation satisfaction, life disturbance, and sleep quality.
