[Clinical study on the effect of acupuncture on pregnancy outcome in patients with prethrombotic infertility after repeated implantation failure].

OBJECTIVE: To observe the effect of acupuncture combined with medication on the pregnancy outcome of kidney deficiency and blood stasis type recurrent implantation failure (RIF) in prethrombotic infertility patients. METHODS: A total of 70 RIF patients of kidney deficiency and blood stasis type who were to undergo freeze-thaw embryo transplantation were randomly divided into control and treatment groups, with 35 cases in each group. Patients in the control group were given the basic treatment of artificial periodic freeze-thaw embryo transfer and oral aspirin enteric-coated tablet, 25 mg each time, twice a day, for 3 consecutive menstrual cycles. Patients in the treatment group were treated with acupuncture on the basis of the control group, 30 min each time, 3 times a week, for 3 consecutive menstrual cycles. The clinical pregnancy rate, embryo implantation rate and live birth rate of the two groups were compared. Before treatment and 1 day before transplantation, the scores of kidney deficiency and blood stasis symptom were compared. The blood flow pulse index (PI) and resistance index (RI) of the uterus spiral artery were detected by Doppler ultrasound before treatment and 1 day before transplantation. The endometrial thickness was detected 1 day before transplantation. The contents of plasma D-dimer, serum homocysteine (Hcy) and serum thromboxane B2 (TXB2) were detected. RESULTS: The clinical pregnancy rate, embryo implantation rate and live birth rate in the treatment group were higher than those in the control group (P<0.05). After treatment, the scores of kidney deficiency and blood stasis symptom, the levels of plasma D-dimer, serum Hcy and TXB2, the PI and RI value in both groups were decreased (P<0.05) compared with those before treatment, and the indexes in the treatment group were decreased (P<0.05) more than those in the control group. There was no significant difference in endometrial thickness between the two groups. In the course of treatments, 7 patients in the control group underwent gastric distension pain, poor appetite, constipation, nausea and other gastrointestinal reactions, while only 2 patients in the treatment group had the above discomfort reactions. CONCLUSION: On the basis of medication, acupuncture can reduce the serum TXB2 content in RIF patients in prethrombotic state, improve vascular endothelial function, enhance endometrial tolerance, alleviate the symptoms of kidney deficiency and blood stasis, reduce drug adverse reactions, and ultimately improve the pregnancy outcome and increase the rate of embryo implantation.

[Effects of auricular thumbtack needle on lactation function and TDP-43/Btn1A1/XDH pathway in primiparous women with cesarean section].

OBJECTIVE: To observe the effects of auricular thumbtack needle on breast feeding and lactation function in primiparous women with cesarean section, and to explore its mechanism of action from the perspective of lactation-related gene expression. METHODS: One hundred cases of primiparous women with cesarean section were randomly divided into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 2 cases were eliminated). The patients in the control group were treated with routine obstetric care. Based on the treatment of the control group, the patients in the observation group were treated with auricular thumbtack needle at Neifenmi (CO18), Xiong (AH10), Xiongzhui (AH11), Shenmen (TF4), and Jiaogan (AH6a), etc., with one side of auricular point selected, only once for a total of 3 d. The lactation initiation time, lactation adequacy rate at postpartum 72 h, exclusive breastfeeding rate at postpartum 42 d, and breastfeeding score after treatment were compared between the two groups. Real-time quantitative PCR and Western blot method were used to detect the mRNA and protein expression levels of TDP-43, Btn1A1 and XDH. RESULTS: After treatment, the lactation initiation time in the observation group was earlier than that in the control group (P<0.01), and breastfeeding score in the observation group was higher than that in the control group (P<0.01). The lactation adequacy rate at postpartum 72 h was 63.8% (30/47) in the observation group, which was higher than 41.7% (20/48) in the control group (P<0.05). The exclusive breastfeeding rate at postpartum 42 d was 72.3% (34/47) in the observation group, which was higher than 47.9% (23/48) in the control group (P<0.05). The mRNA and protein expression levels of TDP-43 and Btn1A1 in breast milk in the observation group were higher than those in the control group (P<0.01), while there was no statistically significant difference in mRNA and protein expression of XDH in breast milk between the two groups (P>0.05). CONCLUSION: The auricular thumbtack needle in addition to routine care could promote lactation initiation, improve lactation adequacy rate and exclusive breastfeeding rate in primiparous women with cesarean section, and the action mechanism may be related to up-regulation of TDP-43 and Btn1A1 expression.

Effect of Different Anesthesia and Puncture Methods of Percutaneous Kyphoplasty on More Than 90-Year-Old Osteoporotic Vertebral Fracture: Advantages of the ERAS Concept.

Background: Percutaneous kyphoplasty (PKP) is an effective minimally invasive technique for the treatment of osteoporotic vertebral fracture (OVF) in recent years. This study focuses on the analysis of PKP surgery and anesthesia in osteoporotic vertebral facture patients over 90 years old with the concept of "enhanced recovery after surgery." Methods: This study reviewed 239 patients who were diagnosed with OVF retrospectively between October 2015 and June 2019. According to the method of anesthesia, these patients were divided into Group A (n = 125) and Group B (n = 114). According to the pedicle puncture approach, these patients were divided into Group C (n = 102) and Group D (n = 137). The anterior vertebral height (AVH) and local kyphosis angle (LKA) were used to evaluate the degree of vertebral damage and restoration. The visual analogue scale (VAS) and the Oswestry Disability Index (ODI) scores were used for assessing functional outcomes. Some parameters were used to assess the perioperative conditions such as operation time, amount of bone cement perfusion, intraoperative fluoroscopy times, anesthesia recovery time, time out of the bed, hospital stay, hospitalization cost, and complications. Results: The visual analogue scale (VAS), Oswestry Disability Index (ODI), anterior vertebral height (AVH), and local kyphosis angle (LKA) 1 day, 1 year after surgery, and at the last follow-up all showed significant improvement (P < 0.05) in comparison with those before surgery both in Groups A and B and Groups C and D. The ODI 1 day after surgery was significantly better in Group B than Group A (P < 0.05). Compared with Group B, Group A required longer time of anesthesia, operation time, anesthesia recovery time, time to get out of bed, and length of hospital stay and more hospitalization costs (P < 0.05). Group D required longer operation time, longer time to get out of bed, more bone cement volume, fluoroscopy time, and more operation hospitalization costs compared with Group C (P < 0.05). Conclusion: We recommend unilateral puncture under local anesthesia for OVF in the patients aged over 90 from the perspective of rapid recovery.

Balloon kyphoplasty as palliative care for painful pathological spinal fracture followed by lung cancer metastasis: A cohort study.

Background: Pathological spine fractures caused by metastases of lung cancer have brought great suffering to patients. Percutaneous kyphoplasty (PKP) has been considered a preferred alternative for painful spinal metastases. The clinical efficacy and safety of PKP for metastatic spinal lesions are urgently to be evaluated. Methods: A cohort study was conducted on 54 cases with pathologic spine fractures caused by metastasis of lung cancer. The correction of kyphosis was assessed by the Cobb angle. The life dependence and quality of the patients were evaluated by the Barthel Index of activities of daily living (ADL) and the quality-adjusted life year (QALY). Patients' survival was carefully recorded. Results: PKP significantly corrected the kyphosis compared with conservative treatment. The ratio of moderate dependence after fracture was clearly increased by PKP. QALY indicated a better life quality brought by PKP. However, PKP could not improve the survival rate of patients. Conclusion: PKP can be used as an effective palliative care treatment for patients with metastatic pathologic spinal fractures of lung cancer.

Effects of different pedicle screw insertion depths on sagittal balance of lumbar degenerative spondylolisthesis, a retrospective comparative study.

BACKGROUND: Few reports to date have evaluated the effects of different pedicle screw insertion depths on sagittal balance and prognosis after posterior lumbar interbody and fusion (PLIF) in patients with lumbar degenerative spondylolisthesis (LDS). METHODS: A total of 88 patients with single-level PLIF for LDS from January 2018 to December 2019 were enrolled. Long screw group (Group L): 52 patients underwent long pedicle screw fixation (the leading edge of the screw exceeded 80% of the anteroposterior diameter of vertebral body). Short screw group (Group S): 36 patients underwent short pedicle screw fixation (the leading edge of the screw was less than 60% of the anteroposterior diameter of vertebral body). Local deformity parameters of spondylolisthesis including slip degree (SD) and segment lordosis (SL), spino-pelvic sagittal plane parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) and lumbar lordosis (LL), Oswestry Disability Index (ODI), and Visual Analog Scale (VAS) for back pain of both groups were compared. Postoperative complications, including vertebral fusion rate and screw loosening rate, were recorded. RESULTS: Except that PI in Group S at the final follow-up was not statistically different from the preoperative value (P > 0.05), other parameters were significantly improved compared with preoperative values one month after surgery and at the final follow-up (P < 0.05). There was no significant difference in parameters between Group L and Group S before and one month after surgery (P > 0.05). At the final follow-up, SD, SL, LL, PT and PI-LL differed significantly between the two groups (P < 0.05). Compared with the preoperative results, ODI and VAS in both groups decreased significantly one month after surgery and at the final follow-up (P < 0.05). Significant differences of ODI and VAS were found between the two groups at the final follow-up (P < 0.05). Postoperative complications were not statistically significant between the two groups (P > 0.05). CONCLUSIONS: PLIF can significantly improve the prognosis of patients with LDS. In terms of outcomes with an average follow-up time of 2 years, the deeper the screw depth is within the safe range, the better the spino-pelvic sagittal balance may be restored and the better the quality of life may be.

[Effect of acupuncture on vascular endothelial function in patients of polycystic ovary syndrome with different glucose tolerance status].

OBJECTIVE: To observe the effect of acupuncture on vascular endothelial function in patients of polycystic ovary syndrome (PCOS) with impaired glucose tolerance (IGT) and normal glucose tolerance (NGT). METHODS: A total of 140 patients with PCOS were divided into an IGT group (70 cases, 11 dropped off) and a NGT group (70 cases, 9 cases dropped off). The patients in the two groups were treated with full-cycle acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), Tianshu (ST 25), etc. once every other day, 3 times a week, for 3 months. Before and after treatment, TCM symptom score, insulin resistance index [including fasting plasma glucose (FPG), 2-hour blood glucose (2hPG), fasting serum insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR)] and vascular endothelial related factors [including asymmetric dimethylarginine (ADMD), endothelin-1 (ET-1), malondialdehyde (MDA), nitric oxide (NO)] were compared between the two groups; in addition, the obese subgroup and non-obese subgroup of the two groups were further compared. RESULTS: Compared before treatment, the TCM symptom scores, ADMD, ET-1 and MDA after treatment were decreased (P<0.05), and NO was increased (P<0.05) in the two groups; FPG, 2hPG, FINS and HOMA-IR after treatment were decreased in the IGT group (P<0.05), the improvement of the above indexes in the IGT group was more significant than that in the NGT group (P<0.05). After treatment, the serum levels of ADMD, ET-1 and MDA were decreased (P<0.05), and NO was increased (P<0.05) in the obese subgroup. In the IGT group, the improvement of serum ADMD, ET-1, MDA and NO in the obese subgroup was more significant than that in the non-obese subgroup (P<0.05). In the NGT group, the improvement of ET-1, MDA and NO in the obese subgroup was more significant than that in the non-obese subgroup (P<0.05). CONCLUSION: Acupuncture could improve vascular endothelial function in PCOS patients, IGT patients have better efficacy than NGT patients, and obese patients have better efficacy than non-obese patients.

[Effect of combined treatment with acupuncture, moxibustion and medication on endometrial receptivity and expression of serum HOXA10 in polycystic ovary syndrome of kidney deficiency and blood stagnation].

OBJECTIVE: To compare the clinical effect of the combined treatment of acupuncture, moxibustion, Chinese herbal medicine and western medication and simple western medication on polycystic ovary syndrome (PCOS) of kidney deficiency and blood stagnation pattern and explore the effect on endometrial receptivity and the expression of serum homeobox gene A10 (HOXA10). METHODS: A total of 60 patients with PCOS of kidney deficiency and blood stagnation pattern were randomized into a combined treatment group and a western medication group, 30 cases in each one. In the western medication group, on the fifth day of menstruation, clomiphene citrate tablets were taken orally, 50 mg each time, once daily, consecutively for 5 days. On the day when the follicle diameter was ≥ 18 mm, chorionic gonadotrophin for muscular injection, a dose of 10 000 U was given. Before sleep, the aspirin enteric-coated tablets were taken orally, 50 mg (except during menstruation). In the combined treatment group, on the base of the treatment as the western medication group, acupuncture and moxibustion were adopted and the Chinese herbal for tonifying the kidney and activating blood circulation was taken orally. The acupoints were Guanyuan (CV 4), Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Zigong (EX-CA 1), etc. Acupuncture was remained for 30 min each time, once every two days and discontinued during menstruation. Chinese herbal was given from the 3rd day of menstruation till the onset of the next menstruation, one dose each day. After consecutive treatment for 3 menstrual cycles in the two groups, the real-time polymerase chain reaction (RT-PCR) method was adopted to determine the expression of serum HOXA10 before and after treatment in the patients of the two groups. The endometrial thickness at ovulatory phase, uterine arterial flow 7 days after ovulation [including uterine arterial pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV)/end diastolic velocity (EDV), meaning S/D], pregnancy rate and the score of Chinese medicine symptoms before and after treatment were compared in the patients between the two groups. RESULTS: ① After treatment, the expression of serum HOXA10 was higher than that before treatment in the patients of the two groups (P<0.01). The increase range in the combined treatment group was larger than the western medication group (P<0.01). ② After treatment, the endometrial thickness at the ovulatory phase was increased in the patients of the two groups (P<0.01). The increase range of the endometrial thickness in the combined treatment group was larger than the western medication group (P<0.01). ③ The pregnancy rate was 46.7% (14/30) in the combined treatment group, higher than 26.7% (8/30) in the western medication group (P<0.05). ④ After treatment, the bilateral uterine arterial PI, RI and S/D values, as well as TCM symptom score were all lower than those before treatment in the patients of the two groups (P<0.01). The decrease range of each index in the combined treatment group was greater than the western medication group (P<0.01, P<0.05). CONCLUSION: The combined treatment with acupuncture, moxibustion and medication effectively improves endometrial receptivity and uterine arterial flow in the patients with PCOS of kidney deficiency and blood stagnation pattern and increases pregnancy rate. The therapeutic effect is better than the simple western medication and its mechanism is probably related to the regulation of serum HOXA10 expression.

[Early-stage hemodynamic changes in dogs with gunshot wound in seawater].

OBJECTIVE: To investigate the hemodynamic changes in the early stages of gunshot wound of dogs in seawater for exploring early treatment protocol. METHOD: Fourteen conventional Beagles models undergoing gunshot wound in seawater were used along with another 2 dogs receiving the wound on land to serve as control. After the dogs were rescued from the seawater, the respiration (R), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), central venous pressure (CVP), pulmonary arterial wedge pressure (PAWP), and cardiac output (CO) were measured continuously in the early stages of the wound (53.62+/-12.19 min following injury), followed by statistical analysis of the results. RESULTS: Compared with the control group, the hemodynamic disturbance of the dogs receiving the wound in seawater was relatively severe during the first 15 min of the wound. The mortality tended to descend relevant to the position of the wounds, in the order of the head, chest, abdomen and limbs. CONCLUSIONS: Gunshot wound in seawater may cause severe hemodynamic changes, resulting in progressive dysfunction of circulation and high mortality rate. Early treatment should be targeted at hemodynamic stabilization in accordance to the characteristic changes during the early stages of the wound.

Microsatellite instability and loss of heterozygosity of fragile histidine triad gene in lung hyperplastic lesions.

OBJECTIVE: To ascertain weather there is any difference in the hyperplastic lesions in the bronchial endothelia between patients with lung cancer and those with pneumonia, so as to find reliable molecular marker for early diagnosis of "genuine" preneoplastic lesions. METHODS: With PCR-denaturing polyacrylamide gel electrophoresis and silver-staining, 82 specimens of bronchial hyperplastic lesions obtained from patients with squamous cell carcinoma (SCC) and 57 matched epithelial lesion specimens obtained from patients with pneumonia were examined for loss of heterozygosity (LOH) and microsatellite instability (MI) of fragile histidine triad (FHIT) gene. RESULTS: Allelic losses of FHIT were common in hyperplastic lesions from patients with SCC, and the frequencies of LOH and MI of the 4 microsatellite sites, D3S1234, D3S1300, D3S1481, and D3S1313 were significant higher in hyperplastic lesions from SCC patients than in those from pneumonia patients (P<0.01). The frequencies of LOH and MI of FHIT gene in cancerous and noncancerous squamous metaplasia were 54%(7/13) and 12%(2/16) respectively, and were 70%(7/10) and 18%(2/8) respectively in cancerous and noncancerous mild to moderate dysplastic lesions. No significant difference was observed between the frequencies of D3S1234, D3S1300, D3S1481, and D3S1313 in cancerous hyperplastic lesions, which were 41%(34/82), 37%(30/82), 38%(31/82), 34(28/82), respectively (P>0.05). CONCLUSION: Hyperplastic lesions showed higher frequency of LOH at the 4 microsatellite sites than MI (P<0.01). The fact that LOH of FHIT is prevalent in hyperplastic lesions in SCC patients but rare in pneumonic patients indicates the significant difference between cancerous and noncancerous hyperplastic lesions. LOH of FHIT may be an early event in the development of squamous cell carcinoma in the lungs and is crucial in the early stage of carcinogenesis, validating the use of FHIT as a molecular marker to identify "genuine" preneoplastic lesions.
