The study on the effective core formulae (CEF) not only summarized traditional chinese medicine (TCM) treatment experience, but also helped reveal the underlying knowledge in the formulation of TCM prescriptions. The aim of the present paper was to investigate the method of data mining for the discovery of core effective formulae for lung cancer. In the present study, a prescription fingerprint approach was used to characterize the staged prescription information of patients. The D index was used to screen potential beneficial herbs. Then, based on a herbal compatibility network, the maximal clique searching algorithm (BK algorithm) and survival analysis were applied to discover CEF for lung cancer, and a mining analysis was made for the 322 cases from Longhua hospital. The correlation between prescriptions and survival time was analyzed by prescription fingerprints. Forty-three potentially beneficial herbs were obtained, and two CEFs were significant for the survival time by a parametric survival model based on lognormal distribution, the results were verified by a multivariate survival model. The rules of combination of the two CEFs basically conform to TCM onco-therapeutic theory of strengthening the body resistance and the actual conditions in clinic. All results showed that the established approach was feasible for discovering the core effective formulae for lung cancer and mining survival data for complex TCM onco-therapy.

Objective To explore the efficacy and safety of greenlight photoselective vaporization of prostate (PVP) in high-risk elder patients with benign prostatic hyperplasia (BPH). Methods A total of 120 high-risk elder patients with BPH underwent PVP procedure. The operating time, blood 1oss, indwelling catheterization and operation-related complications were monitored. The variables such as international prostate symptom score (IPSS), Quality of life (QOL) score, maximum urinary flow rate (Qmax) and residual urine volume (RUV) were recorded and compared pre- and post-operatively. Results All the 120 patients had a good peri-operative condition. The mean operating time was (52. 6 ± 5.8 )min, intraoperative blood loss was (20.4 ±9.5) ml. Among the 120 cases,26 did not received postoperative catheterization. In the other 94 cases received postoperative catheterization, the mean catheterization time was (24. 5 ± 15.9) hour. IPSS and QOL scores decreased from (28.5 ± 3.8) and (5.0 ± 0.8) preoperatively to (7.2 ± 1.8) and (1.5 ± 0.6)postoperatively. Qmax increased from ( 5.2 ± 3.1 ) ml/s to ( 15.2 ± 4.3 ) ml/s, and RUV decreased from ( 118.6 ± 15.2) ml to ( 16. 5 ± 4. 6) ml. There was significant difference for these parameters before and after the operation (Ps ＜ 0. 05 ). Conclusion The PVP is considered to be a safe, effective and minimally invasive procedure to treat BPHin high-risk elder patients. It is easy to manipulate, with advantages of shorter operating time,less blood loss, better tolerance and rapid recovery, especially for high-risk elder patients with BPH.

The pancreatic enzyme-II type collagenase digestion method was adopted for primary culture of osteoblasts, inoculation and passage. They were identified by alkaline phosphatase dye-liquor. N-butanol extract fractions from different processed products of Cibotium barometz were prepared. The above osteoblasts were jointly cultured with protocatechuic acid, protocatechuic aldehyde, kojic acid and the mixed control liquid of the above three substances, and their proliferation was detected by CCK-8. Various n-butanol extract fractions from different processed products of C. barometz showed a significant proliferative effect on osteoblasts in the order of the wined > the heated > the salted > the sand-heated and wined system > the alcohol-processed > the steamed > the crude. The q test showed no significant difference among sand-heated, alcohol-processed and steamed C. barometz, no significant difference between heated and salted C. barometz. Various control substances also showed a certain proliferative effect on osteoblasts in the order of the mixed control > protocatechuic aldehyde > protocatechuic acid > kojic acid. The q test showed no significant difference between protocatechuic aldehyde and protocatechuic acid. All of n-butanol extract fractions from different processed products of C. barometz showed a significant effect on osteoblast proliferation, of which wined C. barometz showed the best effect. All of phenolic compounds such as protocatechuic aldehyde, protocatechuic acid and kojic acid showed a significant proliferative effect on osteoblasts.

OBJECTIVETo study the effect of successive ejaculation on semen analysis parameters in normal men.

METHODSEight ejaculates were collected at daily intervals from 8 normal men. The semen parameters were analyzed according to WHO laboratory manual for the examination of human semen and sperm-cervical mucus interaction.

RESULTSThe semen volumes and total sperm counts decreased gradually day by day, significantly lower from the 5th to the 8th day than the 1st (P < 0.01). The sperm densities also declined day by day, but not significantly. The sperm viability and motility (a + b grade) presented an increasing trend, but with no significance except on the 7th day.

CONCLUSIONWith the increase of the ejaculatory frequency, human semen volumes and the total counts significantly decrease, while sperm viability and motility gradually increase. Successive ejaculation does not affect the quality of human semen.

Objective To compare the saccharometabolism with the pancreatic islets functions and insulin resistance index in children with severe stress. Methods Thirty children with severe stress and 30 healthy children in control group were tested. The levels of fasting blood glucose (FBG), fasting insulin (FINS) and fasting C - peptide (FCP) were detected by radioimmunoassay respectively and insulin sensitivity index (ISI), insulin resistance index (IR) and fasting blood cell function index (FBCI) were calculated statistically. Results There were significant differences between the children with severe stress and the normal controls in the levels of FINS, FCP and FBG,(all P0.05). Conclusion There is insulin resistance with the significant decrease in the insulin sensitivity index and significant increase in insulin resistance index in the children with severe stress, which may cause the disorder in glucose metabolism in children with severe stress.

Objective:To investigate the efficacy and safety of Rituximab (RTX) in treating children with refractory steroid-resistant nephrotic syndrome (SRNS).Methods:The clinical data of 10 children with refractory SRNS receiving RTX in the Department of Pediatrics, Jinling Hospital from September 2013 to March 2018 were analyzed retrospectively.Results:The age of onset of 10 children (including 5 males and 5 females) was (4.47±2.75) years old.The renal biopsy showed focal segmental glomerular sclerosis in 5 cases (50%), minimal change nephropathy in 3 cases (30%), IgM nephropathy in 1 case (10%), and mesangial proliferative glomerulonephritis in 1 case (10%). Ten children received RTX treatment (1 or 4 doses; 375 mg/m 2 once; maximum: 500 mg) at the age of (6.74±2.62) years old.There were 8 patients (80%) receiving a single dose of RTX, 1 patient (10%) receiving 3 doses, and 1 patient (10%) receiving 8 doses.The follow-up time was 11.93 (5.17, 25.66) months.The remission rates at the 3-month follow-up, 6-month follow-up and last follow-up were 30% (3 patients), 40% (4 patients), and 40% (4 patients), respectively.The 24-hour urinary proteinuria and serum albumin levels were improved in 10 children after RTX treatment, but there were no significant statistical difference(all P>0.05). No significant difference was found in humoral immunity and renal function before and after RTX treatment (all P>0.05). During the treatment and follow-up, 3 patients (30%) developed infusion reaction, 2 patients (20%) showed severe pulmonary infection, and 1 patient (10%) died of severe pulmonary infection. Conclusions:RTX is effective in treating some children with refractory SRNS, and a long-term follow-up should be conducted to prevent infection.
