The copy numbers of exogenous gene in transgenic animals is always regarded as an important information of transgenic animals.Thus,simple and sensitive methods are required for the detection of the copy numbers of exogenous gene.Three kinds of transgenic Shanbei white cashmere goats,containing Tβ4-GFP,FGF5s-GFP and VEGF164-GFP,has been obtained by using PiggyBac(PB) transposon system.Fluorescence quantitative PCR was carried out to detect the copy numbers of copGFP.Using Gluc as reference gene,the double standard curves of exogenous gene and reference gene were mapped and the genomic DNA of transgenic goats were analysized by real-time fluorescence quantitative PCR.Moreover,the copGFP/Gluc ratio in the samples was calculated as the copy numbers of copGFP.In addition,Tβ4-GFP transgenic cashmere goats were selected to detect the integration sites by using the genomic walking kit.The results showed that the standard curve equation of copGFP was y=-3.230 6x+39.216 (R2 =0.998 8) and the standard curve equation of Gluc was y=-3.564 8x+38.440 (R2 =0.996 0).The copy numbers of exogenous gene in the transgenic cashmere goats were obtained and the numbers of integration sites in the selected Tβ4-GFP transgenic goats were consistent with the copy numbers of copGFP.As a conclusion,the high throughput,fast and sensitive real-time fluorescence quantitative PCR is an efficient and convenient method for the copy number of exogenous gene in transgenic cashmere goats.

Objective:To study the inhibitory effect of γδT cells on the proliferation of ovarian cancer SKOV3 cells,and to clarify its possible mechanism of inducing apoptosis. Methods:The human ovarian cancer SKOV3 cells cultured in vitro were used as control group,and theγδT and SKOV3 cells were co-cultured for 72 h as γδT cells treatment group.Laser scanning confocal microscope was used to obeserve the morphological changes of nucleus SKOV3 cells,and the inhibitory rate of proliferation of SKOV3 cells in two groups were detected by MTT method;Transwell Chambers was used to detect the cell migration ability,then the apoptotic rates of SKOV3 cells were tested by flow cytometry (FCM).Results:The apoptotic morphology of nucleus of SKOV3 cells in γδT cells treatment group were found under microscope,such as nuclear shrinkage.The MTT resultes displayed that the inhibitory rate of proliferation of SKOV3 cells in γδT cells treatment group was higher than that in control group (P <0.05).The Transwell Chambers results showed that the number of transmembrane cells in γδT cells treatment group was lower than that in control group,and the migration rate was decreased compared with control group (P <0.05).The FCM results showed that the apoptotic rate of SKOV3 cells in γδT cells treatment group was higher than that in control group (P < 0.05 ).Conclusion:γδT cells can inhibit the proliferation and the migration abilities of ovarian cancer SKOV3 cells,and promote the apoptosis.

Objective To investigate the protective effects of FUZHENGJIEDU,a kind of Chinese herb on rats exposed to radon and it's daughter.Methods Twelve male SD rats were exposed with concentration of 40 000 Bq/m3 radon and the exposed dose was 120 work level month (120 WLM),and then all the rats were randomly divided into 2 groups.One group was 120 WLM group (positive control,n=6 ),the other group was FUZHENGJIEDU treatment group (120 WLM exposed rats were given FUZHENGJIEDU 5.0 g every day,n =6),meanwhile 6 rats which lived in the normal environment ( the concentration of radon and it's daughter was lower than 50 Bq/m3 ) as control group.The levels of tumor markers induding carcinoembryonic antigen ( CEA),neuron-specific enolase (NSE),CYFRA21-1 and p53 antibody were tested by ELISA.The rate of p16 gene methylation was measured by methylation-specific PCR (MSP).Results The levels of CEA and NSE in 120 WLM group were (396.62 ± 148.74) and (9.09 ±0.90) μg/L,respectively,significantly higher than those of control group (t =2.583,2.463,P ＜ 0.05).The levels of CEA and NSE in treatment group were (70.89 ±44.71) and (4.31 ±1.37) μg/L,respectively,remarkably lower than those of 120 WLM group (t =2.921,2.526,P ＜0.05 ).The concentrations of CYFRA21-1 and p53 antibody were not significantly different among the three groups (t =1.713,1.963,P ＞ 0.05 ).The rate of p16 gene methylation in BALF cells in 120 WLM group was 16.67％,but in control group and treatment group did not arise p16 gene methylation in BALF cells.Conclusions FUZHENGJIDU would decrease the levels of CEA and NSE and the rate of p16 gene methylation,and could exert it's protective effect on rats exposed to high concentration of radon.

OBJECTIVETo study the clinical characteristics, antibiotics sensitivity and outcome of group B streptococcus (GBS) meningitis in neonates in order to provide the guide for early diagnosis and appropriate treatment.

METHODA retrospective review was performed and a total of 13 cases of neonatal purulent meningitis caused by GBS were identified in the Neonatal Intensive Care Unit of Yuying Children's Hospital of Wenzhou Medical University from January 1, 2005 to May 31, 2013. The clinical characteristics, antibiotics sensitivity test results and outcome were analyzed.

RESULTFever, poor feeding, seizure and lethargy were common clinical signs of neonatal purulent meningitis caused by GBS. Three cases of early onset GBS meningitis received prepartum antibiotics. All 13 cases had abnormal C-reactive protein (CRP) level, and 11 cases had increased CRP within hours after admission. Of the 13 patients, 7 were cured, 4 discharged with improvement, 2 patients died during hospitalization after being given up because of serious complication. The average length of stay for recovered patients was (47 ± 21)d. Acute complications mainly included hyponatremia (5 cases), intracranial hemorrhage (3 cases) , ventriculomegaly (3 cases) , subdural collection (2 cases) , hydrocephalus (2 cases), septic shock (2 cases), cerebral hernia (1 case), encephalomalacia (1 case). One preterm patient with early onset GBS meningitis died 1 month after hospital discharge. Among 7 survivors with 10-24 months follow-up, 3 were early onset GBS meningitis, 2 with normal results of neurologic examination, 1 with delayed motor development, 4 were late onset GBS meningitis, 1 with normal results of neurologic examination, 3 were neurologically impaired with manifestations including delayed motor development (2 cases) and seizures (1 case). All the GBS strains were sensitive to penicillin and linezolid (13/13, 10/10), the susceptibility to levofloxacin, ampicillin and vancomycin were 11/12, 9/10, 8/13 respectively.

CONCLUSIONThe clinical manifestations of neonatal purulent meningitis caused by GBS are usually non-specific. It is associated with long hospitalization, neurological impairments and sequelae. Monitoring of serum CRP level is valuable for early diagnosis. Antepartum prophylaxis, early diagnosis and therapy are vital. Large dose penicillin is the priority choice to treat the neonatal purulent meningitis caused by GBS, linezolid should be used in intractable cases.

Objective To explore the influence of dexmedetomidine on blood gas and inflammation cytokines in patients with one-lung ventilation (OLV).Methods Sixty-two patients undergoing radical resection of pulmonary carcinoma were divided into observation group and control group in sequence,31 cases in each group.All patients treated with intravenous sufentanil 0.3-0.5 μg/kg,propofol 1.5-2.5 mg/kg,midazolam 0.5 mg/kg and rocuronium 0.9 mg/kg for induction of anesthesia;intravenous infusion of propofol 6-8 mg·kg-1 ·h-1 and remifentanil 0.1-0.5 μg·kg-1 ·min-1,intermittent intravenous injection of cisatracurium for anesthesia maintenance.The patients in the observation group were given 1μg/kg loading dose dexmedetomidine 10 min before anesthesia induction (infusion in 10 min),maintaining at 0.5 μg·kg-1 ·h-1 until 30 min before the end of surgery.The patients in the control group were given the same amount of saline as a control.The blood gas analysis index,pH,partial oxygen pressure (PaO2),CO2 partial pressure (PaCO2) and such inflammation cytokines as tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) at OLV (T0),after OLVlh (T1),the end of OLV (T2) were respectively tested,the dosage of propofol in the two groups were recorded.Results The dosage of propofol in observation group was significantly lower than that in the control group (P＜0.05);pH declined in the two groups (P＜0.05),but the difference had no statistical significance;PaO2 was rising then declined in the two groups (P＜0.05),but it was significantly higher in the observation group than in the control group(P＜0.05);PaCO2 in the two groups increased gradually(P＜0.05),it was significantly lower in the observation group than in the control group (P＜0.05);The serum TNF-α,IL-6 in the two groups showed a trend of increasing (P＜0.05),it was significantly lower in the observation group than in the control group (P＜0.05).Conclusion Dexmedetomidine can maintain blood gas stability and reduce inflammation caused by single lung ventilation.

Objective:To analyze clinical features of coronavirus disease 2019 in patients with autoimmune blistering diseases (AIBDs), and to explore risk factors for the development of severe coronavirus disease 2019 in patients with AIBDs.Methods:Clinical data were collected from patients with AIBDs who were hospitalized in Zhongda Hospital, Southeast University from August 2021 to December 2022, and were retrospectively analyzed. Independent sample t-test, Mann-Whitney U test, or chi-square test (Fisher′s exact test) were used to analyze factors associated with severe coronavirus disease 2019 in AIBD patients. Results:A total of 30 patients with AIBDs accompanied by coronavirus disease 2019 were included, they were aged 62.90 ± 15.72 years, and included 16 males and 14 females; pemphigus vulgaris (12 cases, 40.00%) and bullous pemphigoid (13 cases, 43.33%) predominated in the disease spectrum of AIBDs in these patients. The common clinical manifestations of coronavirus disease 2019 were cough (25 cases, 83.33%), fatigue (22 cases, 73.33%), and fever (15 cases, 50.00%) ; most patients had mild clinical symptoms, while 7 (23.33%) developed into severe coronavirus disease 2019, including 2 out of 14 aged 30 - 59 years and 5 out of 16 elderly patients aged ≥ 60 years, and 2 out of the 5 elderly patients finally died. According to the clinical classification criteria of coronavirus disease 2019, the 30 patients were divided into the mild-to-moderate group (23 cases) and severe group (7 cases) ; the duration of AIBDs was significantly shorter in the severe group (10.71 ± 10.72 months) than in the mild-to-moderate group (27.61 ± 19.67 months, t = 2.16, P = 0.040) ; the remission rate of AIBDs was significantly higher in the mild-to-moderate group (21/23) than in the severe group (4/7, χ2 = 4.36, P = 0.037) ; the average daily dosage of methylprednisolone during the last month was significantly lower in the mild-to-moderate group ( M[ Q1, Q3]: 8 [4, 14] mg) than in the severe group (24 [12, 47] mg, U = 133.50, P = 0.007), and the proportion of patients treated with methylprednisolone at an average dosage of > 8 mg was significantly higher in the severe group (6/7) than in the mild-to-moderate group (8/23, χ2 = 5.59, P = 0.031) . Conclusions:Among the patients with AIBDs accompanied by coronavirus disease 2019, the incidence and mortality of severe coronavirus disease 2019 were higher in elderly patients than in young patients. The short course and no-remission of AIBDs, and the average daily dosage of methylprednisolone being>8 mg/d during the last month were risk factors for the development of severe coronavirus disease 2019 in the patients with AIBDs.

Objective To explore the effects of music therapy combined with acupuncture and auricular acupoint pressing in childbirth of primipara. Methods From June to December 2017,this study selected 90 primiparas with childbirth in Obstetrics Department at Zhejiang University Zhoushan Hospital as subjects by convenience sampling. All of primiparas were divided into intervention group and control group with the method of random number table,45 cases in each group. Control group adopted music therapy in which patients listened to their favorite music. On the basis of that in control group,intervention group carried out the acupuncture and auricular acupoint pressing. This study compared the Numerical Rating Scale(NRS),the time when the orifice of uterus ranged from 3 to 10 cm,neonatal Apgar score and blood loss two hours after childbirth of delivery women. Results There was no statistical difference in the score of NRS of primiparas between two groups when the orifice of uterus ≥3 cm(P>0.05). The scores of NRS of intervention group were lower than those of control group with statistical differences 30 min after analgesia and when uterus opened to the full(P<0.05). The time when the orifice of uterus ranged from 3 to 10 cm in intervention group was shorter than that in control group with a statistical difference(P< 0.05). There were no statistical differences in the neonatal Apgar score and blood loss two hours after childbirth of patients between two groups(P> 0.05). Conclusions Music therapy combined with acupuncture and auricular acupoint pressing can ease the labor pain,shorten the time when uterus opens to the full,and is safe for mother and baby and has better effects compared with simply music therapy which is worthy of being popularized and applied.

Objective:To explore the effect of enhanced recovery nursing based on traditional Chinese medicine nursing operation technology in the perioperative period of elderly patients with total hip arthroplasty.Methods:From January 2020 to December 2021, 90 patients with unilateral total hip arthroplasty in Wenzhou Traditional Chinese Medicine Hospital were selected by convenience sampling as research objects. The patients from January to December 2020 were taken as the control group ( n=43) , and the patients from January to December 2021 were taken as the observation group ( n=47) . The patients in the control group adopted the traditional orthopedic perioperative nursing, while the patients in the observation group received the enhanced recovery perioperative nursing based on traditional Chinese medicine nursing operation technology on the basis of the control group. The pain, postoperative recovery and complications were compared between the two groups. Results:The time of first exhaust, eating, getting out of bed and hospital stay after operation in the observation group were shorter than those in the control group, the Visual Analogue Scale (VAS) score at discharge was lower than that in the control group, and the incidence of postoperative gastrointestinal reactions and postoperative urinary retention were lower than those in the control group, with statistically significant differences ( P<0.01) . Conclusions:The enhanced recovery nursing based on traditional Chinese medicine nursing operation technology applied to elderly patients with unilateral total hip arthroplasty during perioperative period can reduce postoperative complications, pain and hospital stay, which is worthy of clinical promotion.

Autophagy and apoptosis are both highly regulated biological processes that play essential roles in tissue homeostasis, development and diseases. Autophagy is also described as a mechanism of death pathways, however, the precise mechanism of how autophagy links to cell death remains to be fully understood. Beclin 1 is a dual regulator for both autophagy and apoptosis. In this study we found that Beclin 1 was a substrate of caspase-3 with two cleavage sites at positions 124 and 149, respectively. Furthermore, the autophagosome formation occurred, followed by the appearance of morphological hallmarks of apoptosis after staurosporine treatment. The cleavage products of Beclin 1 reduced autophagy and promoted apoptosis in HeLa cells and the cells in which Beclin 1 was stably knocked down by specific shRNA. In addition, the cleavage of Beclin 1 resulted in abrogating the interaction between Bcl-2 with Beclin 1, which could be blocked by z-VAD-fmk. Thus, our results suggest that the cleavage of Beclin 1 by caspase-3 may contribute to inactivate autophagy leading towards augmented apoptosis.
