Objective To analyze the curative effects and complications of ventriculo-peritoneal shunt in treating hydrocephalus caused by different diseases in children. Methods The data of 289 children with hydrocephalus who were performed ventriculo-peritoneal shunt were examined and the incidence rate of complications was analyzed. Results Thirty-seven incidences of complications occurred in 24 patients with the total incidence rate of 12.46%.There was obstruction of proximate tube in five cases,distal end in two cases,with the obstruction rate of 2.42%.Postoperative infection happened in nine cases(3.11%).Bacterial culture was positive in three cases,two of which were Staphylococcus epidermidis and Bacillus coli in the other one.Negative results were found in six patients for the bacterial culture.Subdural hematoma occured in one case,and tube break after injury in two cases.Slit ventricle syndrome broke out seven times in three cases,leakage of cerebrospinal fluid in two,exposure of pumps in three,and subcutaneous hydrops in two.Four cases(1.38%)were dead from infection. Conclusion Ventriculo-peritoneal shunt is preferred for hydrocephalus in children if the complications are well prevented and controlled.

Objective To observe the clinical efficacy of acupuncture in treating malignant pleural effusion (MPE).Method Eighteen MPE patients confirmed by histopathological and/or cytological examinations were treated by acupuncture by selecting Yunmen (LU 2), Qimen (LR 14), Zhangmen (LR 13), Jingmen (GB 25), Guanyuan (CV 4), Zhongji (CV 3), Shuidao (ST 28), and Guilai (ST 29) as the major points. The treatment was given once every other day, 3 times a week, 4 weeks as a treatment course, and the therapeutic efficacy was evaluated 1 course later.Result Of the 18 patients, 6 got complete remission, 9 got partial remission, 2 achieved stable condition, while 1 didn’t respond to the treatment, and the total effective rate was 83.3%. Of the 5 cases with encapsulated pleural effusion, 2 got complete remission and 3 got partial remission, and the total effective rate was 100.0%. The amount of pleural effusion (anteroposterior diameter of the fluid), comprehensive score of symptoms, item scores of the symptoms, and Karnofsky Performance Status (KPS) score were changed significantly after treatment (P<0.01).Conclusion Acupuncture is an effective method in treating MPE of moderate volume, and it can swiftly improve the symptoms and promote the quality of life.

Objective:To investigate the characteristics and significance of insulin-like growth factor 1(IGF- 1) and insulin-like growth factor binding protein 2 (IGFBP2) expressions in ankle cartilage of patients with Kashin-Beck disease (KBD).Methods:In this case-control study, 10 KBD patients who were hospitalized in the Department of Orthopedics of Shaanxi Provincial People's Hospital from January 2010 to December 2016 were selected as KBD group, and 10 patients with ankle fracture caused by trauma but without talus injury during the same period were selected as control group, the cartilage tissues of the two groups were collected. IGF-1, IGFBP2 positive cells, the mRNA and protein expressions of IGF-1, IGFBP2 in the cartilage tissues were detected by immunohistochemistry, real-time fluorescent quantitative PCR and Western blotting, respectively. According to the expressions of IGF-1 and IGFBP2 in ankle cartilage of KBD patients, a patient with amputation caused by trauma was selected in Shaanxi Provincial People's Hospital, and ankle joint cartilage was taken to prepare chondrocytes for in vitro cell verification experiments. The chondrocyte were divided into control group (0 ng/ml T-2 toxin), T-2 treatment group (20 ng/ml T-2 toxin) and T-2+ IGFBP2 silenced group (20 ng/ml T-2 toxin+ 50 nmol/L IGFBP2 siRNA), the MTT method and dimethyl methylene blue staining were used to detect the activity of chondrocyte and the secretion of sulfated glycosaminoglycan (sGAG). Results:In the control group and the KBD group, the number of IGF-1[(47.26 ± 8.97), (68.15 ± 7.42) cells] and IGFBP2 positive cells [(27.56 ± 5.40), (71.85 ± 7.62) cells] in the cartilage tissues were significantly different ( t = 4.487, 9.402, P < 0.01). Compared with the control group, the IGF-1, IGFBP2 mRNA and protein expression levels in KBD group were significantly higher, the differences were significantly different ( t = 3.340, 20.700, 4.684, 8.699, P < 0.05 or < 0.01). In cell experiment, the chondrocyte activitives and sGAG contents of the control group, T-2 treatment group, and T-2+ IGFBP2 silenced group were significantly different ( F = 226.70, 80.66, P < 0.01); among them, the cell activitives and sGAG contents of the T-2 treatment group and T-2+ IGFBP2 silenced group were lower than those of control group ( P < 0.05), and the T-2+ IGFBP2 silenced group were higher than those of the T-2 treatment group ( P < 0.05). Conclusions:The expressions of IGF-1 and IGFBP2 in the ankle cartilage of KBD patients are significantly higher. Silencing IGFBP2 gene can reduce the inhibitory effect of T-2 toxin on chondrocyte activity and the secretion of sGAG.

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Sanyinjiao" (SP 6) on urodynamics indices in rats with overactive bladder (OAB) after cystostomy, and to explore its regulation mechanism on bladder function.

METHODSForty-eight Sprague-Dawley female rats which received cystostomy were randomly divided into a blank group (group A), a blank Sanyinjiao group (group B), a blank non-acupoint group (group C), a model group (group D), a model Sanyinjiao group (group E) and a model non-acupoint group (group F), 8 rats in each one. The model of OAB was established with 1% acetic acid solution perfused into the bladder in the group D, group E and group F. No treatment was given to the group A and group D. Acupuncture was applied at bilateral "Sanyinjiao" (SP 6) in the group B and group E, followed by EA after the arrival of qi. Acupuncture was applied at bilateral non-acupoint in the group C and group F, followed by EA with continuous wave, 2 Hz of frequency for 30 min. The treatment was given for continuous 5 urination cycles. The BL-420 E+ biological function experiment system was used to measure and record the changes of indices of bladder pressure and urodynamics.

RESULTSCompared with the group A, the bladder capacity and urine output in the group B were significantly increased (both P<0.05), and the urination rate was increased in the group C (P<0.05); the differences of each index between group C and group B were not statistically significant (all P>0.05). Compared with the group D, the capacity pressure, bladder capacity, detrusor pressure, urinary output and urination rate in the group E were all increased (all P<0.05). Compared with the group F, the capacity pressure and detrusor pressure in the group E were increased (both P<0.05).

CONCLUSIONThe EA at "Sanyinjiao" (SP 6) could significantly improve urine function in rats with OAB after cystostomy, but its regulation effect on urination is not obvious in rats with non-OAB.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

OBJECTIVETo investigate the role of endogenous hydrogen sulfide (H2S) in erectile dysfunction (ED) induced by androgen deficiency.

METHODSWe randomly divided 30 eight-week-old healthy male SD rats into six groups: 2-week control (A), 4-week control (B), 2-week castration (C), 4-week castration (D), 2-week castration + androgen replacement (E), and 4-week castration + androgen replacement (F), those in groups E and F subcutaneously injected with testosterone propionate (TP) at the physiological dose of 3 mg/kg per day after castration, while those in the other groups with isodose oil instead. At 2 and 4 weeks after operation, we determined the level of serum testosterone (T) , intracavernous pressure (ICP) , mean carotid arterial pressure (MAP) of the rats, measured the concentration of H2S in the plasma and corpus cavernosum tissue, and detected the expressions of cystathionine-P3-synthase (CBS) and cystathionine-gamma-lyase (CSE) by immunohistochemistry and Western blot.

RESULTSThe serum T level was significantly lower in group C ([0.63 +/- 0.15] nmol/L) than in A ( [ 16.55 +/- 4.17] nmol/L) and E ( [ 18.99 +/- 4.62] nmol/L) (P <0.05), as well as in group D ([0.70 +/-0.22] nmol/L) than in B ([15.44 +/-5.18] nmol/L) and F ([20.99 +/-6.41] nmol/L) (P <0. 05) , and so were ICP/MAP after 5 and 7 V electrical stimulation of the pelvic ganglia (P <0. 05) , H2 S concentration (P <0.05), and the expressions of CBS and CSE (P <0.05). The expressions of CBS and CSE proteins were also significantly decreased in group C as compared with D (P <0.05).

CONCLUSIONThe reduced expressions of CBS and CSE may inhibit the H2 S signaling pathway, which might be one of the mechanisms underlying androgen deficiency-induced ED in rats.

The stable and controllable quality of decoction pieces is an important factor to ensure the efficacy of clinical medicine. Considering the dilemma that the existing standardization of processing mode cannot effectively eliminate the variability of quality raw ingredients, and ensure the stability between different batches, we first propose a new strategy for Chinese medicine processing technologies that coupled with individuation processed and cybernetics. In order to explain this thinking, an individual study case about different grades aconite is provided. We hope this strategy could better serve for clinical medicine, and promote the inheritance and innovation of Chinese medicine processing skills and theories.

Quality control is one of the key scientific tissues in the modernization of traditional Chinese medicines (TCM). In order to overcome the deficiencies of assessment indexes, including little systematization and quantification, as well as loose association with clinical efficacy and dosage, a new integrated method named controllability pyramid ( CP) is first proposed in this paper. In addition, some study cases are used to explain how this model is constructed. We hope the establishment of CP could promote the clinical-orien- ted integrated innovation research of TCM, and provide control strategy and technology examples for improving the quality of Chinese medicines and clinical efficacy.
