ABSTRACT
Objective:To compare the social support levels as understood by family doctor team members in township hospitals/community health centers, and village clinics/community clinics, and their influencing factors, in order to provide reference for improving the work status of family doctor team members and enhancing the quality of family doctors′ contracted services.Methods:A multi-stage random cluster sampling method was used to sample medical workers from contracted family doctor teams in township hospitals/community health centers and their subordinate village clinics/community clinics in 6 counties (cities, districts) of Tai′an city, Shandong province. In August 2020, a questionnaire survey was conducted on the perceived level of social support among family doctor team members using the perceived social support scale. Descriptive analysis was conducted on the data, and independent sample t-tests and one-way ANOVA were used to conduct univariate analysis on the influencing factors of perceived social support scores of family doctor team members at different levels, while multiple linear regression analysis was used to conduct multivariate analysis. Results:A total of 765 valid questionnaires were collected, with 203 and 562 from township hospitals/community health centers and village clinics/community clinics, respectively. The total perceived social support scores of family doctor team members in township hospitals/community health centers and village clinics/community clinics were (65.56±10.29) and (67.31±10.14), respectively, featuring statistically significant differences ( t=-2.11, P<0.05). In-mirage marital status ( β=0.18, P=0.008), good/very good self-rated health status ( β= 0.25, P=0.048), participation of work-related training within one year ( β=0.17, P=0.010), relatively satisfied/very satisfied for job promotion ( β= 0.17, P=0.046), as well as above/far above average self-rated economic status as ( β=-0.15, P=0.027), were the influencing factor on the perceived social support scores of family doctor team members in township hospitals/community health centers. In-marriage marital status ( β= 0.12, P=0.002), good/very good self-rated health status ( β=0.14, P=0.026), junior or intermediate level or above professional title ( β=-0.11, P=0.003; β=-0.10, P=0.006), participation of work-related training within one year ( β= 0.14, P<0.001), and relatively satisfied/very satisfied for job promotion ( β= 0.16, P<0.001) were the influencing factors on the perceived social support scores of family doctor team members in village clinics/community clinics. Conclusions:Members of the family doctor teams in primary medical institutions in Tai′an city had a higher level of understanding of social support. There were differences in the social support levels of family doctor team members between the two levels of primary medical and health care institutions, and the influencing factors were not completely consistent. Targeted measures should be taken based on specific circumstances to enable them to better receive and perceive support from family and friends, and to improve the quality of family doctors′ contracted services.
ABSTRACT
Objective:To evaluate the efficacy and safety of Rezūm Water Vapor Thermal Therapy system in the treatment of patients with benign prostatic hyperplasia (BPH).Methods:The clinical data of 22 patients with benign prostatic hyperplasia treated with Rezūm Water Vapor Thermal Therapy system in Boao Yiling Life Care Center in Hainan from December 2020 to January 2021 were retrospectively analyzed, with age of (61.0±5.9) years, prostate volume of (43.7±8.4) ml. international prostate symptom score (IPSS) of (19.3±3.7), quality of life (QOL) score of (4.2±0.8), maximum urinary flow rate (Q max) of (11.9±3.4) ml ml/s, and residual urine volume (PVR) of (14.0±19.0). For 19 patients with sexual life, the International Index of Erectile Function Questionnaire-5 (IIEF-5) were 17.0±5.5, the Men's Sexual Health Questionnaire-Ejaculatory Dysfunction Score (MSHQ-EjD) ejaculatory function score were 10.0±3.2, and the ejaculatory satisfaction score were 1.5±1.0. Twenty-two patients underwent Rezūm Water Vapor Thermal Therapy under intravenous anesthesia (general anesthesia without intubation) in the dorsal lithotomy position. The Rezūm system consisted of reusable thermal steam treatment device and disposable prostate thermal steam treatment instrument. The thermal steam treatment device used radiofrequency energy to heat sterile distilled water, generating high-temperature steam at 103℃. In a 9-second timeframe, the tissue temperature within each treatment area was raised approximately 70℃, causing cell death and resulting in a shrink in prostate tissue volume. The disposable prostate thermal steam treatment instrument could be inserted through a cystoscope and had a retractable needle tip that extends to a length of 10.25 mm. The needle tip had 12 evenly distributed holes arranged in three rows of four holes each, with a spacing of 120° between rows, allowing for even diffusion of thermal steam along the circumference. The patient was placed in a lithotomy position, and the disposable prostate thermal steam treatment instrument was used to examine the prostate, urethra, and bladder via cystoscopy, assessing the lateral lobes and median lobe of the prostate. The tissue spacing within each field of view of the treatment instrument is 0.5 cm, and the distance from the bladder neck to the verumontanum is calculated. The first needle was injected at 3 o’clock along the left lobe, withdrawing 2 fields of view each time. During the release of thermal steam, the needle tip was positioned perpendicular to the prostate urethral mucosa, and each needle injection delivered 0.42 ml of sterile distilled water-formed thermal steam into the prostate tissue. The thermal steam injection lasted for 9 seconds, followed by a 2-3 seconds waiting period before retracting the needle tip. One needle was injected per 2 fields of view, progressing towards the proximal urethra of the verumontanum. The same method was used to treat the right lobe. For cases with significant median lobe enlargement, two fields of view were retracted at the bladder neck, and the needle was inserted at a 45° angle. The second needle was injected at intervals determined by the extent of median lobe enlargement. Each puncture point was observed for no significant bleeding, and the instrument was then removed, with an F16/F18 silicone catheter left in place. The operative time as well as indwelling catheter time were recorded. The clinical parameters such as IPSS, QOL, prostate volume, Qmax, PVR, QOL, IIEF-5 and MSHQ-EjD at preoperative and 12 to 22 weeks post operation were compared. Adverse events from the Rezūm procedure to 12-22 weeks postoperatively were recorded. Results:All the operations were successfully completed. The operation time of Rezūm system was 3.9±1.6 min, and the indwelling catheter time after operation was 4.8±1.1 days. The IPSS scores of 22 patients at 12-22 weeks after operation were 4.4±3.3, whose reduction was 14.9±4.4 compared with these at baseline( P<0.01). The PV was (37.7±8.4)ml, Qmax was (25.5±9.6)ml/s, PVR was (6.2±8.1)ml, and QOL was 1.6±0.9, all demonstrating statistically significant differences compared to preoperative values ( P<0.05). Among the 19 cases with sexual activity, the IIEF-5 score was 20.4±3.2, and the ejaculatory function score of MSHQ-EjD was 13.1±3.1, both showing statistically significant differences compared to preoperative scores ( P<0.05). The ejaculatory satisfaction score of MSHQ-EjD was 1.1±0.5, and there was no statistically significant difference compared to preoperative scores ( P>0.05). None of the 22 cases required medication or further surgical treatment for BPH after surgery. There were no urethral injuries, rectal or bladder perforations during the surgeries, and no severe complications such as rectal fistula or bladder neck contracture occurred postoperatively. There were no deaths reported. Postoperative discomfort in the urethra occurred in 19 cases, urethral pain in 8 cases, hematuria in 15 cases, poor sleep quality in 2 cases, and constipation in 1 case, all of which resolved within 7 to 10 days after surgery. Erectile dysfunction and retrograde ejaculation occurred in one case each at 4 to 5 weeks postoperatively but did not reoccur thereafter. Prostatitis and nodular hyperplasia of the middle lobe of the prostate occurred in one case each at 21 weeks and 25 weeks postoperatively, respectively, and no treatment was administered. Conclusions:In the real world, the short-term overall effect of Rezūm Water Vapor Thermal Therapy system in the treatment of benign prostatic hyperplasia is satisfactory, which shows good efficacy and safety.

ABSTRACT
This study was aimed to evaluate the applicability of common Chinese word segmentation software used in the literature study of traditional Chinese medicine (TCM) text,in order to put forward ideas on developing specialized TCM text word segmentation software.By means of installing and operating Chinese word segmentation software,the text segmentation experiment was conducted on TCM text samples.Aspects,such Chinese word segmentation accuracy,speed,maneuverability,reliability,extendibility,portability and other characteristics,were compared among different Chinese word segmentation software.The results showed that there were differences on the accuracy,speed,maneuverability,reliability,extendibility,portability among different Chinese word segmentation software.It was difficult to achieve best performance on different aspects by single software.Through the comparison of different Chinese word segmentation software,the Pan-Gu Segment software showed the best performance on accuracy,with good maneuverability,and high word segmentation efficiency,which was the most suitable for word segmentation in TCM text.It was concluded that developing specialized TCM text segmentation software may be the best solution to meet the requirement of text segmentation in TCM literature study.Basic studies should be strengthened from aspects,such as the construction of standard TCM copus,the completion of TCM dictionary base,the introduction,optimization and innovation of word segmentation algorithm,as well as the development of word segmentation software for TCM text.
ABSTRACT
AIM: To study the effects of disulfiram/copper complex (DSF/Cu) on ultrastructures and mechan-ical properties of human breast cancer and normal breast epithelial cells by atomic force microscopy (AFM) based on the nanoscale resolution and piconewton force measurement level.METHODS: The change of cell cycle and apoptotic rate of MCF-7 cells and MCF-10A cells induced by DSF/Cu were compared by flow cytometry.The cell surface morphology, ultra-structure, height, width and roughness were detected by AFM.The effects of DSF/Cu on the hardness (Young’s modu-lus) of the 2 kinds of cells were determined by AFM with indentation technique.RESULTS: DSF/Cu significantly in-duced apoptosis of the MCF-7 cells in a dose-dependent manner, whereas had little effect on the MCF-10A cells.The cell cycle analysis showed that DSF/Cu induced G2 /M arrest in the MCF-7 cells, but led to G0 /G1 arrest in the MCF-10A cells.The AFM images showed that the MCF-7 cells shrank and showed smaller and smoother morphology, and the filopo-dia were retracted obviously, even some became into lamellipodia, or disappeared completely after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.The quantitative analysis indicated that the MCF-7 cells showed smaller width and larger height, and the root mean square roughness and average roughness were decreased significantly in a dose-dependent manner after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.However, little effect in the MCF-10A cells was observed.The biomechanics test at a single cell level demonstrated that the Young’s modulus of the MCF-7 cells and MCF-10A cells were both increased, yet the proportion increased in the MCF-7 cells was much higher than that in the MCF-10A cells after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.CONCLUSION: DSF/Cu has strong antitumor effect on breast cancer with high efficiency and low toxicity by changing the properties of the biomechanics specifically.
ABSTRACT
Objective To evaluate the charateristics of CT and MR imaging of struma ovarii(SO).Methods 10 lesions of 10 pa-tients confirmed by pathology were analyzed retrospectively.6 cases were performed plain and enhanced CT scan and 4 were under-went MR before operation.Imaging features were analyzed retrospectively correlated with histological findings.Results All the SO tumors were appeared as solitary,well-defined,lobulated or oval masses.The largest diameter was less than 10 cm.Ascites were found in 4 cases.Six of SOs were solid-cystic and four were cystic.The cystic portion was low density or high density on CT images. High density cysts were shoewed in 4 cases.On MR images,the cystic portion was hypointenstiy on T1 WI and hypo/hyperintensity on T2 WI.Vacuum phenomenon (hypointenstiy on T1 WI and extremly hypointensity on T2 WI)was observed in 1 case.Solid compo-nent and cystic wall showed remarkable enhancement.Conclusion CT and MR images of SO can reflect its histopathologic charater-istics,which provides important value in the diagnosis and differential diagnosis of SO.
ABSTRACT
Objective:To study the effect of sevoflurane inhalation anesthesia on stress reaction and kynurenic acid ( KYNA) level in serum of the patients with laparoscopic cholecystectomy .Methods:Totally 48 patients undergoing laparoscopic cholecystectomy were randomly divided into two groups.Group S(n=24) received sevoflurane inhalation and group V (n=24) received intravenous general anesthesia.The levels of norepinephrine (NE), epinephrine (E), cortisol (Cor), KYNA and neutrophil and the neutrophil/lympho-cyte ratio were measured at five time points, namely T1(before the anesthesia), T2 (just after the surgery) , T3(in the morning of the first day after the surgery ) , T4 ( in the morning of the second day after the surgery ) and T5 ( in the morning of the third day after the surgery).The correlation of Cor, NE, E and NLR with KYNA was studied as well.Results:The levels of Cor, NE and E at the three time points after the surgery (T2, T3 and T4) in group V were significantly higher than those before the surgery (T1) with statistically significant difference (P0.05).And the levels of Cor, NE and E at the three time points after the surgery (T2, T3 and T4) in group S were markedly lower than those in group V at the same time point (P<0.05).After the surgery (T2, T3, T4 and T5), KYNA levels in group V were significantly decreased and NLR values in group V were significantly increased when compared with those of T 1.In group S, KYNA levels and NLR values after the surgery (T2, T3, T4 and T5) were markedly increased , which were higher than those in group V at the same time point with statistically significant difference (P<0.05).The correlation analysis indicated the level of KYNA displayed positive correlation with the levels of NLR , Cr, Z and E (P<0.05).Conclusion:Sevoflurane inhalation anesthesia can inhibit the increase of stress reaction and KYNA level in the patients with laparoscopic cholecystectomy , which may be related with its anti-in ammatory properties .

ABSTRACT
Aim To study the mechanism of DSF-Cu induced apoptosis of human nasopharyngeal carcinoma CNE-2 Z cells by affecting the function of mitochondria and cytoskeleton. Methods The cell cycle,the rate of apotosis,the levels of intracellular ROS and MMP in CNE-2 Z cells were tested by flow cytometry after trea-ted with different concentration of DSF-Cu. The chan-ges of the cell surface morphology, ultrastructure, cell height, width and roughness were detected by AFM. The distribution and reorganization of cytoskeleton F-actin were observed by Laser scanning confocal micro-scope. Results Cells were incubated with different concentration of DSF-Cu ( 0 ~200 nmol · L-1 ) for 24 h, the apoptotic ratio increased significantly and the treatment of DSF-Cu resulted in a concentration-de-pendent accumulation of CNE-2Z cells in G2/M phase. Furthermore,the treatment of DSF-Cu was able to in-crease the production of intracellular ROS and decrease the MMP in CNE-2Z cells. In addition,AFM imaging showed that compared to the control group,with the in-crease of DSF-Cu concentration,the CNE-2Z cells be-came smaller, cytoplasm condensed, the height in-creased,and the surface roughness reduced. Moreover, the filopodia became shorter, shrinked and even com-pletely destroyed after treated with different concentra-tion of DSF-Cu. At last,the LSCM image showed that the fluorescence intensity of F-actin networks was de-creased, then the structure was rearranged and de-stroyed obviously by treated with DSF-Cu. Conclusion DSF-Cu can induce apoptosis and arrest cell cycle at G2/M phase in CNE-2Z cell through a mitochondria-dependent pathway. Above findings highlight the appli-cations of AFM at the single cell level for the investiga-tion of antineoplastic drug in nasopharyngeal carcinoma therapy.

ABSTRACT
Objective A new field of organ donation after cardiac death (DCD) has been explored to create additional source to clinic transplantation in China.Methods A 33-years old male patient underwent permanent vegetation state for more than 2 years in ICU after severe head injury.His relatives gave writing consent to donate his organs in order to save his renal failure father and others,if possible,in case of cardiac death.On July 27,2005,the patient's heart arrested.Clinic death was announced.The case was immediately referred to transplant team and Maastricht-V DCD organ procurement was emergently performed and two kidneys were harvested. Estimated warm ischemic time was about 40 min followed by 8 h cold ischemic time.Two adults received the grafts.One of recipients was donor's biological father,namely it was the first case of deceased related renal transplantation (DRRTx) in China.Results Both recipients developed delayed graft function postoperatively and eventually recovered after few weeks.By submission of this article,the DRRTx patient has survived with normal renal function for 77 months (6 years and 5 months).Unfortunately,other patient died from fungus pneumonia after 56 months with normal renal function.Conclusion Non-controlled Maastricht-V DCD could be an additional source to transplantation if prompt reaction could be taken.
ABSTRACT
To construct a lentiviral shRNA vector targeting human protein phosphatase 1D magnesium-dependent (PPM1D) gene and detect its effectiveness of gene silencing in human gliomas, specific siRNA targets with short hairpin frame were designed and synthesized. DNA oligo was cloned into the pFU-GW-iRNA lentiviral expression vector, and then PCR and sequencing analyses were conducted to verify the constructs. After the verified plasmids were transfected into 293T cells, the lentivirus was produced and the titer of virus was determined. Real-time quantitative PCR and Western blot were performed to detect the PPM1D expression level in the infected glioma cells. PCR and Western blot analyses revealed the optimal interfering target, and the virus with a titer of 6×10(8) TU/mL was successfully packaged. The PPM1D expression in human glioma cells was knocked down at both mRNA and protein levels by virus infection. The expression of PPM1D mRNA and protein was decreased by 76.3% and 87.0% respectively as compared with control group. The multiple functions of human glioma cells after PPM1D RNA interference were detected by flow cytometry and cell counting kit-8 (CCK-8). Efficient down-regulation of PPM1D resulted in significantly increased cell apoptosis and reduced cell proliferation and invasion potential in U87-MG cells. We have successfully constructed the lentiviral shRNA expression vector capable of stable PPM1D gene silencing at both mRNA and protein levels in glioma cells. And our data gave evidence that the reduced cell growth observed after PPM1D silencing in glioma cells was at least partly due to increased apoptotic cell death.
ABSTRACT
Objective To investigate the effects of electro-acupuncture on muscular tension and motor function in the flaccid,paralytic limbs of stroke survivors.Methods Seventy-two stroke survivors with flaccid,paralytic limbs were divided randomly into a control group and an electro-acupuncture group.Both grourps received routine therapy and rehabilitation training,but the electro-acupuncture group was also treated with electro-acupuncture.Muscular tension and motor function in the flaccid,paralytic limbs in both groups were evaluated by modified Ashworth scale (MAS)and Fugl-Meyer scores before treatment and at the end of 4 weeks.Results After treatment,in 24 patients of the electro-acupuncture group and 10 patients of the control group muscular tension had increased 1-2 grades.The effectiveness rate(68.57%)in the electro-acupuncture group wag higher significantly than that(27.03%)in the control group(P＜0.01).Fugl-Meyer scores in the electro-acupuncture group were significantlv higher than those in the control group(P＜0.01).Conclusion Electro-acupuncture supplementing traditional rehabilitation improves muscle tension in flaccid,paralytic limbs and promotes the recovery of motor flunction after stroke.
ABSTRACT
Objective To evaluate the role of the combination of angiotensin receptor blocker (ARB)and angiotensin corwerting enzyme inhibitor(ACEI)in functional protection and long-term survival of renal allograft. Methods Thirty-two renal transplant recipients without diabetes mellitus,whose albuminuria concentration in 24-hours collection was more than 0.5 g/d or serum Cr concentration was higher than 177 mmol/L,were randomly divided into experimental group(n=23,male 9 and female 14 cases,mean age 40 years)and control group(n=9,male 5 and female 4 cases,mean age 35 years).Combination of ARB(Valsartan,80rag Qd)and ACEI(Benazapril,20 mg Bid)theraPy was given to each patient every day for 3 years in experimental group.The recipients in control group never received this administration.The serum Cr concentration,albuminuria in 24-hours collection and survival of renal allograft were compared between the 2 groups after 3 years. Results There was significant difference(P＜0.05) of serum Cr concentration between experimental group and control group(252.2±117.9 mmol/L VS 375.3±203.0 mmol/L),especially for chronic allograft nephropathy (CAN)patieats(282.4±147.3 mmol/L vs 528.7±107.8 mmol/L,P＜0.01).There was no difference (P＞0.05)in terms of the values of alburninuria(1.0±0.6 g/d vs 1.3±0.7 g/d)and survival of renal allograft(76 months VS 71 months)after 3 years between 2 groups.Comclusion The administration of ARB+ACEI could protect function of renal allograft with different pathological changes especially for CAN.
