Objective To investigate the effect of four traditional Chinese drugs for reinforcing kidney combined with Tongqiao Huoxue Decoction on serum neurotransmitters and neurological func-tion in patients with post-stroke cognitive impairment(PSCI).Methods A total of 110 patients with PSCI were randomly divided into treatment group and control group,with 55 cases in each group.The control group was treated with donepezil tablet,while the treatment group was treated with four tradi-tional Chinese drugs for reinforcing kidney and Tongqiao Huoxue Decoction on the basis of the control group.The total effective rate,the Mini-Mental State Examination(MMSE)score,the Montreal Cogni-tive Assessment(MoCA)score,the National Institutes of Health Stroke Scale(NIHSS)score and the Barthel Index(BI)as well as serum levels of acetylcholine(ACh),dopamine(DA),norepinephrine(NE),5-hydroxytryptamine(5-HT),neuron-specific enolase(NSE),visinin-like protein-1(VILIP-1),myelin basic protein(MBP),and heat shock protein 70(HSP70)before and after treatment were compared between the two groups.Adverse reactions in both groups were recorded.Results The total effective rate was 90.91％in the treatment group,which was significantly higher than 76.36％in the control group(P＜0.05).After treatment,the MMSE score,MoCA score and BI as well as serum levels of ACh,DA,NE,5-HT and HSP70 in the treatment group were significantly higher than those in the control group,while the NIHSS score and serum levels of NSE,VILIP-1 and MBP were significantly lower than those in the control group(P＜0.05).The total incidence rate of adverse reactions in the treatment group and the control group was 12.73％and 9.09％respectively,which showed no significant between-group difference(P＞0.05).Conclusion Four traditional Chinese drugs for reinforcing kidney combined with Tongqiao Huoxue Decoction can promote the secretion of cognition-related neurotransmitters in patients with PSCI,accelerate the repair of neurological damage,and safety is relatively high.

Objective:To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China.Methods:Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use.Results:Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol ( OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol ( OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased ( OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased ( OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant ( P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient ( P<0.01). Conclusion:For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

Objective:To investigate the value of 3D printing combined with intraoperative electrophysiological monitoring in excision of cerebellopontine angle (CPA) tumor.Methods:The clinical data of 43 patients with CPA tumor, admitted to our hospital from October 2016 to October 2019, were collected and analyzed. These patients were voluntarily divided into ordinary group ( n=27) and optimized group ( n=16). Patients in the ordinary group were operated microscopically, and those in the optimized group were operated microscopically with 3D printing combined with intraoperative electrophysiological monitoring. The degrees of tumor resection and neurological functions (facial and auditory nerve function, swallowing function, limb activity) improvements were compared between the two groups. Results:The degrees of tumor resection of the optimized group were significantly higher than those of the ordinary group ( P<0.05), and the improvement of facial and auditory nerve function in the optimized group was significantly better than that in the ordinary group ( P<0.05). There was no significant difference in improvements of swallowing function and limb activity between the two groups ( P>0.05). Conclusion:The 3D printing combined with intraoperative electrophysiological monitoring can improve the resection rate of CPA tumor, protect the facial auditory nerve, and improve the quality of life of patients after surgery.

BACKGROUND: Diphosphonate has a predominant therapeutic effect in the prevention and treatment of postmenopausal osteoporosis. Ibandronate, as a new-type diphosphonate preparation, is gradually becoming a study hotspot.OBJECTIVE: This study is to investigate the efficiency of ibandronate in interfering postmenopausal osteoposis by observing bone mass loss related indexes in ovariectomized rats, and made a comparison with nilestriol.DESIGN: A completely randomized grouping, and controlled animal experiment.SETTING: Study Room for Bone metabolism, Fudan University Medical College.MATERIALS: Forty SD female rats, aged 10-12 months, were involved in this study. Ibandronate was provided by the State Key Laboratory of Jiangsu Institute of Atomic Medicine. Nilestriol was produced in the Shanghai 12th Pharmaceutical Factory.METHODS: This experiment was carried out in the Study Room for Bone Metabolism, Institute of Radiation Medicine,Shanghai Medical University between August 1996 and June 1998. The rats were divided into 4 groups by a lot, 10 rats in each: sham-operation group, ovariectomized group, ovariectomized+ibandronate group and ovariectomized +nilestriol group. In the sham-operation group, only small pieces of adipose tissue around the ovary were resected from the rats.Three months after operation, each rat was intragastrically administrated with 1 mL normal saline; In the ovariectomized group, ovariectomized+ibandronate group and ovariectomized +nilestriol group, each rat was subjected to bilateral ovariectomy, and 3 months later, they were intragastrically administrated with normal saline, ibandronate water solution [0.5 mg/( kg·d)] and nilestriol suspension [1 mg/(kg· time)] respectively. Each rat in the latter three groups was administrated for 90 days, twice in the first week, and then once a week.MAIN OUTCOME MEASURES: Left femur was taken out, and its dry weight and ash weight were measured. Calcium content of bone was determined with an atomic absorption spectrophotometer, bone density of the whole body with a bone density apparatus, the bone density at the juncture of 1/2 right femoral bone length with a single photon bone density apparatus, and femoral anti-bending force was determined with a universal testing machine. Alkaline phosphatase were determined by dynamical method with an automatic biochemistry analyzer, urine calcium by EDTA titration method, urine creatinine by picric kinetic method, and urinary hydroxyproline by modified proline assay.Trabecular area was calculated.RESULTS: Forty rats were involved in the final analysis. ① Bone dry weight, bone ash weight and bone calcium content in the ovariectomized group were significantly lower than those in the other 3 groups, respectively (t =13.58-52.98, P ＜0.05). ② Femoral bone density and bone density of the whole body of rats in the ovariectomized group were significantly lower than those in the other 3 groups (t =3.31-5.61, P＜0.05), while anti-bending force was close between ovariectomized group and the other 3 groups (P＞0.05). ③ The ratio of urine calcium to urine creatinine was significantly lower in the ovariectomized+ibandronate group and ovariectomized +nilestriol group than in the ovariectomized group (t =4.04, 3.30, P＜0.05). No significant difference in the alkaline phosphatase and ratio of urinary hydroxyproline to urinary creatinine existed among the groups (P ＞ 0.05). ④Trabecular area of vertebrae in the ovariectomized group was significantly smaller than that in the other 3 groups (t =2.22,2.41,3.45,P ＜ 0.05), while the trabecular area of tibia in the ovariectomized group was only smaller than that in the ovariectomized +nilestriol group (t =2.45, P＜ 0.05).CONCLUSION: Osteoporosis apPears obviously in the SD rats 3 months after ovariectomy. Ibandronate has obviously inhibitory effects on the bone mass loss of rats with postmenopausal osteoposis, and it is equivalent to nilestriol in inhibitory effect.
