In recent ten years, general practitioner (GP) training and practice develops rapidly in China. It has established a relatively complete GP training system, including medical college education and standardized residency training. However, the path of continuing professional development and clinical skills improvement for GP after standardized residency training is still unclear. The concept of GP with special interest (GPSI) has been proposed these days, and it has put forward a new development direction for the career path of GP. In this article, on the basis of understanding the current status of GPSI in China, we try to discuss its advantages and problems, and then propose our suggestions for its future development.

Objective To better promote the health education and health promotion among patients with chronic disease, general practitioners (GPs) in the community should master the knowledge of non-communicable diseases (NCDs). This paper aimed to describe the current situation of GPs' knowledge about prevention and treatment of NCDs. Methods Self-designed questionnaires were issued to 1 077 GPs in community health service centers, and all GPs finished the questionnaire without assistance. The content of questionnaire includes the general information of GPs and six questions focusing on NCDs. Results Overall, 1 076 GPs completed the questionnaire, and the response rate was 99.9% (1 076/1 077). With regard to the six questions about NCDs, 90.4% (973/1 076) of GPs were well aware of the diagnosis of hypertension. Apart from that, the knowledge of diabetes mellitus (60.9%, 655/1 076), factors related to NCDs (70.2%, 755/1 076), the concepts of mental illness (52.0%, 560/1 076) and the clinical significance of tumor markers (87.9%, 946/1 076) among GPs were adequate, while more than half of the GPs did not know a lot about home oxygen therapy. Conclusion The mastering level of knowledge about prevention and treatment of NCDs among GPs varies that they need further improvement.

Objective To explore the effects of improved preparation before urodynamic examination in the elderly patients with voiding disfunction.Methods Totally 424 elderly patients underwent urodynamic examination after improvement of the preparation approach according to pathophysiological characteritics of the elderly patients,and 248 elderly patients before the approach improved in our center were collected as control.The compliance,discontinuation and repetition rate of urodynamic examination were compared between the two groups.Results The compliance of patients who used the improved preparation approach was significantly higher than control (92.5％ vs.59.3％,x2=106.428,P＜0.001).Whereas the discontinuation and repetition rates of urodynamic examination in the improved group were decreased as compared with control group ( 1.2％ vs.6.9％,x2 =14.176,P=0.0002; 8.5％ vs.21.4％,x2 =21.487,P＜0.001).Conclusions The improved preparation approach according to the pathophysiological characteritics of elderly patients is worthy to popularize in the urodynamic centers.

Objective To investigate the voiding patterns of term and preterm newborns and whether voiding in term and preterm neonates was accompanied by any cortical arousal. Methods Between May 2013 and September 2013,64 hospitalized newborns at Neonatal Intensive Cave Unit in the Frist Affiliated Hospital of Zhengzhou University were recruited in this study. In these patients,31 cases were term newborns(20 male,11 female)and 33 cases were preterm newborns(19 male,14 female). The term and preterm newborns gestational ages at birth were(38. 2 ± 1. 2) weeks and(32. 1 ± 1. 6)weeks,weighted(3. 3 ± 0. 4)kg and(1. 7 ± 0. 3)kg,respectively and postnatal ages at study were[4 - 16(10. 5 ± 3. 6)]days and[4 - 16(11. 2 ± 3. 1)]days. The voiding volume(VV),post - void residual volumes(PRV),body movement rate and voiding frequency(VF)in 4 hours as well as the volume of milk and liquid fed at the same time frame were recorded and analyzed,retrospectively. At the same time electrocardiogram(ECG)and electroencephalogram(EEG)were recorded. The changes of heart rate(HR),EEG frequency,respiratory frequency (RF)during the 5 s period and 30 s before and after voiding onset were compared respectively. For cortical arousal definition the recommendations of the International Pediatric Work Group on Arousals(2005)were used. Results A total of 184 times of voiding were recorded. In preterm newborns,the VV and body movements rate were significantly lower compared with the term newborns[(21. 8 ± 7. 9)mL and(41 ± 21)% vs(26. 4 ± 8. 7)mL and(62 ± 19)% , t = 3. 75,4. 20,all P ﹤ 0. 05]. However,the VF and PRV were significantly higher in preterm newborns[(1. 7 ± 0. 9) mL and(3. 2 ± 1. 1)times vs(1. 2 ± 0. 7)mL and(2. 6 ± 0. 9)times,t = 2. 47,2. 38,all P ﹤ 0. 05]. Bladder voiding in these infants happened only during QS. In term newborns,HR frequency was higher during the 5 s interval before and after voiding onset when compared with the 30 s period before voiding onset[(152 ± 6)times/ min and(152 ± 5) times/ min vs(147 ± 6)times/ min,t = 5. 30,5. 76,all P ﹤ 0. 05]and the EEG frequency[(2. 6 ± 0. 1)Hz and (2. 6 ± 0. 1)Hz vs(1. 5 ± 0. 1)Hz,t = 70. 0,70. 0,all P ﹤ 0. 05]. While the HR and EEG frequency of preterm neo-nate was not changed before and after bladder voiding onset. The RF of both term and preterm neonates were not changed before and after bladder voiding onset. Conclusions The voiding patterns between term and preterm were sig-nificantly different and cortical arousal was found only in term neonates,which indicate the term newborns have better mature bladder function and development of nervous system.

Abstract: Objective　To investigate the infection of Anisakis in marine fish sold in Fuxin, and conduct molecular identification and evolutionary tracing of third-stage larvae to determine Anisakis species. Methods　From 2018 to 2021, marine fish sold in the market were collected randomly, and the third stage larvae of Anisakis were detected in marine fish sold in the market by direct dissection, and the morphological characteristics were used to preliminarily identify species by microscopy; the total DNA was extracted, the internal transcribed spacer sequence of the ribosomal DNA of Anisakis was amplified, and the sequence alignment and evolution analysis were carried out. Results　A total of 289 market-sold sea fish samples of marine fish sold in the market were dissected and 84 samples of Anisakis were detected with a detection rate of 29.1%, of which the infection rates of hairtail and small yellow croaker were higher, at 41.4% and 41.2%, respectively. BLAST comparison of 28 sequences revealed eight species of anisakids, including Anisakis pegreffii, Anisakis simplex, Anisakis typical, Raphidascaris trichiurid, Contracaecum muraenesoxi, Hysterothylcaium zhoushanensis, Hysterothylacium amoyense and Hysterothylcaium fabri,belonging to the genera Anisakis and Hysterothylacium. The phylogenetic tree constructed from 28 sequences generally formed two topological branches, with Anisakis pegreffii, Anisakis simplex, and Anisakis typical forming three separate clusters as the topology branch of Anisakis genus. However, meanwhile, Hysterothylacium, Contracaecum, and Raphidascaris formed a separate topological branch. Conclusions　The marine fish sold in Fuxin City have severe anisakid infection, with a wide variety of anisakid species, the dominant species being Anisakis pegreffii.

Objective To assess the value of the urine flow acceleration(UFA)versus maximum urinary flow rate (Qmax) for diagnosis of bladder outlet obstruction (BOO) in benign prostate hyperplasia (BPH).Methods A total of 50 men with BPH and 50 normal men were included in this study.Urodynamic examinations were performed in all patients according to the recommendations of the International Continence Society.Prostate volume,UFA and Qmax of each patient were analyzed and the results were compared between two groups.Results The UFA and Qmax of BPH group were much lower than that of the control group [(2.05±0.85)ml/s2 vs.(4.60±1.25)ml/s2 ; (8.50±1.05)ml/s vs.(13.00±3.35)ml/s,P＜0.05].The prostate volume in BPH group was increased compared with control group [(28.6±9.8) ml vs.(24.2±7.6)ml,P＜0.05].As diagnosis standard of UFA＜2.05 ml/s2 and Qmax＜ 10 ml/s,the sensitivity and specificity of UFA and Qmax in diagnosing BOO were (88％,75 ％)vs.(81％,63％).While compared with the result of P-Q chart,the Kappa values in correspondence analysis were 0.55 vs.0.35.The sensitivity,specificity and Kappa value of UFA in diagnosing BOO in BPHs were slightly higher than that of Qmax in comparison with the gold standard (BOO diagnosed by P-Q figure).Conclusions The UFA is a useful urodynamics parameter in diagnosing BOO of BPH.

OBJECTIVETo observe the effect of salidroside on tic behavior and in vivo dopamine DA) and serotonin (5-HT) levels in Tourette syndrome (TS) model rats.

METHODSForty rats were randomly divided into the blank control group, the TS model group, the haloperidol-treated group (0.5 mg/kg x d(-1)), and the salidroside-treated group (50 mg/kg x d(-1)), 10 in each group. TS rat model was induced by imino-dipropio-nitrile (IDPN). Peritoneal injection of haloperidol and salidroside was started from the 4th day of modeling in the haloperidol-treated group and the salidroside-treated group respectively. Normal saline was peritoneally injected to rats in the blank control group and the TS model group respectively. Stereotyped behavior was scored, and changes of DA and 5-HT levels in blood and striatum were measured before modeling, after modeling, and after intervention.

RESULTSCompared with the blank control group, the score of the tic behavior was elevated (P < 0.01) , levels of DA and 5-HT in plasma and striatum were reduced in the model group (P < 0.01, P < 0.05). Compared with the same group after modeling, the tic behavior score decreased and plasma DA levels increased in the two treated groups after intervention (P < 0.01). 5-HT content increased in the salidroside-treated group (P < 0.01). Compared with the model group after intervention, the tic behavior score was significantly reduced (P < 0.01), and DA levels in plasma and striatum were elevated (P < 0.01, P < 0.05) in the salidroside-treated group and the haloperidol-treated group. Compared with the haloperidol-treated group, the tic behavior score increased (P < 0.01), DA levels in plasma and striatum were lowered (P < 0.01, P < 0.05), the 5-HT level increased in plasma and striatum (P < 0.01, P < 0.05) in the salidroside-treated group.

CONCLUSIONSIn the salidroside-treated group, the tic behavior was significantly reduced, and DA levels in plasma and striatum were elevated. Its mechanism might be related to regulating activities of dopamine neurons in striatum.

Objective To investigate the high mobility group box chromosomal protein-1 (HMGB1) levels in patients with acute pancreatitis (AP); and to study the relationship between the serum level of HMGB1 and the severity of AP. Methods The patients' serum HMGB1 concentrations were determined right after admission, 24, 48 hour after admission. The levels of HMGB1 were measured by ELASA kit and its relationship with the severity of AP was analyzed. 20 healthy adults were treated as the control group. Results At the time of admission, and 24, 48 hours after admission, the serum HMGB1 levels in AP patients were (8.05 + 1.60 ), ( 8.04 ± 1.39 ), ( 8.25 ± 1.56) ng/ml, respectively, which were significantly higher than that in the healthy control [ ( 2.20 + 0.57 ) ng/ml, P ＜ 0. 01]. There were 35 patients with severe acute pancreatitis (SAP) and 27 patients with mild acute pancreatitis (MAP). The HMBG1 levels in patients with SAP were (7.99 + 1.69) ,(8.12 ± 1.40), (8.13 ± 1.34) ng/ml, and they were (8.12 + 1.52), (7.92 +1.40), (8.39 ± 1.81 )ng/ml in patients with MAP, and the difference between the two groups was not statistically significant. Conclusions The serum HMGB1 level in AP patients was significantly higher than that in healthy controls, but it was not related with the severity of AP.
