Methods The clinicopathologic records of 306 patients with cervical squamous cell carcinoma of stage Ⅰb and Ⅱa who underwent radical hysterectomy and pelvic lymphadenectomy were retrospectively analyzed, and the prognostic factors were explored by univariate and multivariate methods. Independent prognostic factors were identified by COX proportional hazards regression model. Results The overall 5-year survival rate of these 306 patients was 78.1%. In univariate survival analysis, the poor prognostic factors included poor differentiation, positive pelvic lymph nodes, deep stromal invasion, parametrial extension, tumor size≥4 cm, and lymph vascular space involvement (P

Objective:To observe the instant analgesic effect of Governor Vessel-regulating and collateral-unblocking acupuncture method in treating primary headache and to inherit and carry forward the academic achievements of Gao's acupuncture school in Yanzhao (Hebei Province) area. Methods:Eighty eligible primary headache patients were randomized into an observation group and a control group following their visiting sequence, 40 patients in each group. The observation group was intervened by Yanzhao Gao's Governor Vessel-regulating and collateral-unblocking acupuncture, and the control group was intervened by ordinary acupuncture method. The visual analogue scale (VAS) was used to evaluate the headache intensity before and after the first treatment session in the two groups, to compare the instant analgesic effect of the two acupuncture methods. Results:After the first treatment session, the VAS scores dropped significantly in both groups (both P<0.05). The change of VAS score after the initial treatment in the observation group was significantly different from that in the control group (P<0.05). The percentage of patients with headache completely vanished instantly after the first treatment was markedly higher in the observation group than that in the control group (P<0.05). Conclusion: The two acupuncture methods both can produce a significant instant analgesic effect in treating primary headache, while Yanzhao Gao's Governor Vessel-regulating and collateral-unblocking acupuncture method is superior to ordinary acupuncture method.

Objective To study the therapeutic efficacy of Chinese botulinum toxin type A (CBTX- A) in masticatory spasm patients.Methods 16 patients with masticatory spasm were treated with CBTX-A local injection.12 patients showed jaw clench with masseter and temporalis affected (type Ⅰ).Four showed jaw clench and deviation to one side with pterygoid muscle affected unilaterally or bilaterally (type Ⅱ).All patients showed paroxysmal clenched jaw with difficulty in opening their mouths.There were no other clinical manifestations.CT and MRI did not reveal any intracerebral abnormalities.The efficacy and adverse effects were observed.Results CBTX-A were injected into 16 patients,resulting in a significant improvement of symptoms in 13 cases (4 cases of unilateral type Ⅰ,7 of 8 cases bilateral type Ⅰ,2 of 4 type Ⅱ).The spasms ceased within 3-10 days after the injection,and the effects lasted for 8-26 weeks.Four patients were observed to have slight masseter weakness after the injections,which recovered within a few weeks.The benefit persisted after identical repeated injection.Conclusion CBTX-A injection is an effective and safe treatment for masticatory spasm.

OBJECTIVETo observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

METHODSA prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases). CSO was plastered at Shenque (RN8) for 5 days after operation. The time of exhaustion, defecation, the recovery of intestinal peristalsis, integrals of TCM syndrome, and serum levels of motilin (MOT)and somatostatin (SS) were observed.

RESULTSCompared with the placebo group, the condition of exhaustion and defecation, the recovery of intestinal peristalsis on the 3rd day after operation was all improved (P < 0.05). The integrals of TCM syndrome at day 2, 3, and 4 were more significantly lowered in the CSO group than in the placebo group (P < 0.01, P < 0.05). The total effective rate of TCM syndrome was 95.3% in the CSO group, better than that in the placebo group (91.8%, P < 0.05). Compared with the placebo group, the serum MOT level increased and the serum SS level decreased at day 5 after operation in the CSO group (P < 0.05).

CONCLUSIONSThe plastering of CSO at Shenque (RN8) could advance the time of exhaustion and defecation, and improve patients' clinical symptoms. And patients could tolerate well.

Objective To explore the value of susceptibility-weighted imaging (SWI) for the assessment of chronic renal injury. Methods Thirty-nine patients with clinical diagnosis of chronic renal injury (RI group) who underwent routine renal MRI and SWI examination were retrospectively analyzed. They were divided into mild injured group (15 cases) and moderate to severe injured group (24 cases) by estimated glomerular filtration rate (eGFR). At the same time, 17 volunteers without chronic renal injury who had normal serum creatinine (Scr) and blood urea nitrogen were recruited as control group. All subjects underwent routine renal MRI and SWI examination. The ratios of cortex to medulla were measured and calculated in both kidneys' magnitude image and susceptibility weighted image, which were indicated as C/MMAG and C/MSWI. Independent sample t test was used to compare the differences of C/MMAG and C/MSWI between control group and RI group, and paired sample t test was used to compare the differences betweenC/MMAG and C/MSWI in each group. One-way ANOVA was used to compare the difference of C/MMAG and C/MSWI between the control group and the different RI groups. ROC was employed to assess the diagnostic efficacy of C/MMAG and C/MSWI in renal injury. Pearson linear correlation analysis was used to evaluate the correlation between C/MMAG, C/MSWI and eGFR, Scr in patients with renal injury. Results The C/MMAG and C/MSWI in the RI group were 1.101±0.039 and 1.071±0.046, respectively. C/MSWI was obviously lower than C/MMAG, and the difference was statistically significant (t=5.056, P<0.01). There was no significant difference between C/MMAG and C/MSWI in the control group (P>0.05). The C/MMAG and C/MSWI in the RI group were obviously lower than those in the control group, and the difference was statistically significant (t=4.564, 6.122;P<0.01).The C/MMAG and C/MSWI in the mild injured group and the moderate to severe injured group were significantly lower than those in the control group, the difference was statistically significant (P<0.05). While the differences of those between mild injured group and moderate to severe injured group showed no statistical significance (P>0.05). The area under ROC of C/MMAG and C/MSWI in diagnosis of renal injury were 0.853 and 0.952, respectively. C/MMAG was positively correlated with eGFR (r=0.460,P<0.01). Conclusions Susceptibility-weighted imaging can be used to assess chronic renal injury. Although it cannot reflect the degree of renal function damage, it has some value in the early diagnosis of mild renal injury.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.
