Objective To investigate the surgical treatment and clinical outcome of patients with intracranial posterior circulation poor-grade aneurysms. Methods The clinical data of 35 patients with intracranial posterior circulation poor-grade aneurysms were collected. Seventeen patients were World Federation of Neurosurgical Societies (WFNS) grade IV and 18 patients were WFNS grade V. Twenty- nine patients were definitively treated with open microsurgery treatment(2 patients) and endovascular treatment (27 patients). Six patients received conservative treatment, including 4 patients only receiving external ventricular drainage to decrease intracranial pressure and 2 patients only receiving medical treatment. The nerve function were evaluated by Glasgow outcome scale (GOS) at discharge from hospital and 1 and 12 months after operation. Results In the patients who received conservative treatment, 5 patients were dead in hospital, and 1 patient got good outcome after 12 months. In the patients who received surgical treatment, at discharge from hospital good outcome were achieved in 15 patients (51.7%), poor outcome in 9 patients (31.0%), and death happened in 5 patients (17.2%). At 1 month after operation, good outcomes were achieved in 14 patients (48.3%), poor outcome in 9 patients (31.0%), and death happened in 6 patients (20.7%). At 12 months after operation, good outcome were achieved in 18 patients (62.1%), poor outcome in 5 patients (17.2%), and death happened in 6 patients (20.7%). Conclusions Patients with posterior circulation poor-grade aneurysms have better prognosis after positive surgical treatment.

Objective To compare the effectiveness and safety of different intracranial stents assisted coil embolization of intracranial aneurysms and to discuss the selection of different stent assisted embolization of intracranial aneurysm.Methods From 2007 April to 2012 April,118 cases (a total of 128 wide-neck aneurysms) with intracranial aneurysms were analyzed retrospectively.This included the use of 70 neuroform,38 Enterprise,and 20 Solitaire AB stents forthe treatment of intracranial aneurysms.The successful use,aneurysm occlusion at the immediate post-operation,and early period of peri-operative complications were recorded from those clinical data in order to assess the effectiveness and safety of the different intracranial stents,which assisted coil embolization of intracranial aneurysms.Rank sum test and x2 test were used for statistics.Results Three aneurysms assisted with Neuroform stent were planted unsuccessfully,and the Enterprise and Solitaire stents were placed successfully.The embolism results of three stents after immediate postoperative angiography aneurysm: Neuroform stent occlusion rate was 40.0％ (28/ 70),the tumor residual rate was 38.6 ％ (27/70),and the partial embolization rate was 21.4 ％ (15/70) ; The Enterprise stent occlusion rate was 42.1％ (16/38),the tumor residual rate was 36.8 ％ (14/38),and the partial embolization rate was 21.1％ (8/38).The Solitaire AB stent occlusion rate was 40.0 ％ (8/20),the tumor residual rate was 35.0 ％ (7/20),and the partial embolization rate was 25.0 ％ (5/20).There were not significant differences in aneurismal occlusion (H =0.12,P ＞ 0.05).Early peri-operative complications results were: Neuroform stent occurred in 7,Enterprise frame in 4,and Solitaire AB stent occurred in 2.There were no significant differences in the incidence of complications in the early period after coiling (x2 =0,P ＞ 0.05).Conclusions Three kinds of intracranial stents assisted embolization of intracranial aneurysms are applied safely and effectively.The stent may be chosen according to morphology of parent artery and stent biological character.

Objective To explore the etiology and pathogenesis of Hirschsprung disease(HD) and the role of nitric oxide in pathophysiology of HD. Methods The whole amount preparations of dilative and transitional segments were stained by NADPH\|diaphorase histochemistry mothod,and colonic walls were digested by dispase. Then the NOS positive nervous structure were observed by light and scanning electron microscope. Results In dilative segment, under light microscope, ganglion and neuron were bigger and more darkly stained. Intraganglionic neurons distributed mostly in peripheral area of ganglion and basal part of ganglionic fiber bundles. Under scanning electron microscope, the neurons were denser, more nerve fibers from them and connected with each other in all dimensions. And more transverse connected fibers between neurons which were arranged along muscle fibers. Myenteric plexus even connected with the submucosal plexus by nerve fibers which passed through circular muscle layer. In transitional segment, under light microscope, intraganglionic neurons cytoplasm were lightly stained and also variedly. The ganglion and neurons of the segment were smaller, and the fibers from them were thinner and paler than those of the dilative segment. Under scanning electron microscope, neurons' density was lower, the fiber connection between neurons and muscle fibers/neurons was lesser. In the transitional segment, neurons and nerve fibers were distributed linearly along the longitudinal muscle fibers. Conclusion Our results indicated that an intimate relationship existed between the development of Hirschsprung disease and abnormal distribution and metabolism of NOS positive neuron in colonic wall.

Abstract: Objective　To understand the situation of drug-resistant tuberculosis screening and epidemiological characteristics of multi-drug resistant tuberculosis (MDR-TB) and pre-extensively drug resistant tuberculosis (pre-XDR-TB) in Changsha, in order to provide a scientific basis for improving the quality of drug-resistant tuberculosis prevention and control in the city. Methods　Demographic information and drug susceptibility date of etiologically positive pulmonary tuberculosis patients in Changsha from 2018 to 2021 were collected, the successful rate of resistance screening, incidence and tendency in MDR-TB and pre-XDR-TB in patients included in this study were statistically analyzed accordingly. 　　Results From 2018 to 2021, the successful screening rates were 86.2%, 87.7%, 81.9% and 71.5% for MDR-TB and 82.2%, 84.8%, 76.9% and 68.2% for pre-XDR-TB, respectively. In each year, MDR-TB patients identified accounted for 7.6% (101/1 222), 6.5%(124/1 774), 6.6%(110/1 555) and 6.3%(99/1 478), and pre-XDR-TB patients identified accounted for 3.6%(46/1 219), 3.8%(69/1 766), 4.4%(69/1 495) and 4.6%(69/1 436), correspondingly. The incidence of MDR-TB showed a slowly downward trend, while the incidence of pre-MDR-TB showed a slowly upward trend, with neither decreasing nor increasing trends being statistically significant (（χ2=1.947，0.806，P>0.050). The incidence of MDR-TB in the retreatment failure population was 66.6% (2/3), and the others, failure initial treatment and recrudescence populations were 23.5% (19/81), 16.7% (2/12) and 15.2% (70/461), respectively. Similar to the incidence above, the incidence of pre-XDR-TB was 16.7% (2/12) among patients who failed in initial treatment, and 12.2% (9/74), 9.8% (43/439), and 4.5% (2/44) among the others, recrudescence and returned patients, respectively. The incidence rates of MDR-TB and pre-XDR-TB in different populations were significantly different (χ2=117.600，59.030，P<0.05). Conclusions There are still areas for improvement in tuberculosis drug resistance surveillance system in Changsha. On the premise of paying attention to patients in retreatment failure, other, initial treatment failure and relapse patients, high sensitivity molecular drug susceptibility testing, and scientifically efficient screening strategies must be explored.

OBJECTIVETo explore the lower urinary tract symptoms (LUTS), especially those in the urinary storage phase, following transurethral resection of the prostate (TURP), and to improve the postoperative management and patients' quality of life after TURP.

METHODSA total of 86 patients with benign prostate hyperplasia (BPH) underwent TURP, and were interviewed on urinary symptoms at 1, 3, 7, 15 and 30 days after removal of the catheter. The patients were divided into two groups according to whether they had preoperative detrusor instability and/or compliance of the bladder (Group A) or not (Group B), and observed for the changes in IPSS scores and urinary storage symptoms after removal of the catheter.

RESULTSComplete follow-ups were achieved in 71 cases, 28 with detrusor instability and/or compliance of the bladder and the other 43 without. Their IPSS scores on the 1st, 3rd, 7th, 15th and 30th day after removal of the catheter were 8.1 +/- 2.5, 7.2 +/- 3.1, 6.3 +/- 3.8, 5.3 +/- 4.2 and 2.4 +/- 3.4, respectively, with statistically significant differences between the 7th and the 1st as well as the 30th and the 15th day (P < 0.05), but not between the 1st and the3rd nor the 15th and the 7th day (P > 0.05). On the 1st day, the cardinal symptoms in the urinary storage phase were urinary frequency, urgency and incontinence; the scores on IPSS and urinary storage symptoms were 10.4 +/- 3.3 and 9.3 +/- 3.8 in Group A and 6.2 +/- 2.8 and 5.2 +/- 2.7 in Group B, with significant differences between the two groups (P < 0.05). After treatment with tolterodine and alpha-adrenoreceptor inhibitor, neither IPSS scores nor the scores on urinary storage symptoms showed any significant differences between Groups A and B on the 15th and 30th day (P > 0.05).

CONCLUSIONThe lower urinary tract symptoms following TURP, especially those in the urinary storage phase, are correlated with preoperative bladder function, and getting improved gradually after surgery.

OBJECTIVETo investigate the effect of the combination therapy of biofeedback with electrical stimulation on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) through clinical trials.

METHODSA total of 140 cases of diagnosed CP/CPPS were randomly divided into a control group (n = 20), a biofeedback group (BF, n = 40), an electrical stimulation group (ES, n = 40), and a biofeedback plus electrical stimulation group (BF + ES, n = 40). The latter three groups were treated by corresponding methods 5 times a week for 2 weeks, while the controls left untreated. After the treatment, all the patients were followed up for 30 days. The NIH chronic prostatitis symptom index (NIH-CPSI) scores and the results of uroflowmetry were obtained and compared before and after the treatment.

RESULTSCompared with the control group, the scores on pain, urinary symptoms and quality of life (QOL) and the total NIH-CPSI scores were obviously decreased (P < 0.05), and the maximum flow rate (MFR) markedly improved (P < 0.05) in the BF, ES and BF + ES groups after the treatment, with significant differences between the former two and the latter one (P < 0.05), but not between the BF and ES groups (P > 0.05), nor in the control group before and after the treatment (P > 0.05).

CONCLUSIONThe combination therapy of biofeedback with electrical stimulation has a synergistic effect on CP/CPPS by alleviating pain and urinary symptoms, improving QOL and elevating MFR.

Objective To evaluate the efficacy and safety of acute ureteroscopy for the treatment of ureterie stones during middle and late pregnancy.Methods From June 1998 to March 2005,17 pregnant women(mean age,27 years;age range,21-35 years)with ureteric stones were treated by ureteroscopy when the fetus was at 20-36 weeks of gestation(mean,29 weeks).All the cases presented with urgent symptoms such as recurrent renal colic(11 cases),fever(4)or acute obstructive anuria(2).Among 17 cases,the stones(between 6 mm?7 mm and 13 mm?21 mm)were located in the upper(8 cases),middle(5)or lower ureter(4);and on the left side(5 eases),on the right(10)and on both(2)of the lower ureter. Mild hydronephrosis were observed in 6 cases and moderate hydronephrosis in 11,Of the 17 cases,14 under- went ureteroscopic pneumatic lithotripsy;in 1 case the calculi were pushed to the renal pelvis;and 2 cases were treated by Double-J catheter drainage.Results All the urgent symptoms in 17 cases were relieved after treatment.The stone-free rate of initial treatment was 82.4%(14 of 17).Three cases with residual stones were treated by Douhle-J catheters,which were replaced every 3 months until the calculi were re- moved.No abortion,premature delivery or complications such as ureter perforation occurred.Mild renal colic occurred in 1 case after insertion of Douhle-J catheter,and it was relieved 3d later;gross hematuria occurred in l case and disappeared 6 d later without treatment.All 17 patients had normal delivery and gave birth to healthy children.Conclusions Ureteroscopy is a safe and reliable method for the treatment of ureteric calculi during middle and late pregnancy.

To clone and analyze a member of the Auxin/indole-3-acetic acid (Aux/IAA) gene family, RgIAA1, from Rehmannia glutinosa. The transcriptional EST database of R. glutinosa was used to clone the new Aux/IAA gene by cDNA probe of AtIAA14. Bioinformatics was applied to analyze the sequence characteristics of RgIAA1 protein and construct phylogenetiC trees. Quantitative RT-PCR has been applied to detect the transcription level of RgIAA1 in seven tissues as well as in leaves under three stresses. The results showed that, the cDNA sequence of RgIAA1 contains 903 bp was obtained. The open reading frame (ORF) of RgIAA1 was 681 bp encoding 226 amino acids, which has typical structural domains and characteristic sequence of Aux/IAA family proteins. RgIAA1 showed the highest expression level in unfolded leaf, followed by the stem. And the expression of RglAA1 was quickly decreased with leaf growing up. The transcription level increased under continuous cropping conditions while it reduced both in salinity and waterlogging stresses. RgIAA1, an Aux/IAA gene from R. glutinosa has been obtained for the first time, which can lay the foundation for further studies about its molecular function in development and responses to stress.
