This study was aimed to establish a qualitative model of near-infrared spectroscopy in order to accurately and rapidly identify several mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs. The near-infrared diffuse reflectance spectroscopy combined with OPUS software was used to analyze the spectral characteristics of these samples. The pattern recognition method was explored through cluster analysis. And the accuracy of the model was verified. The results showed that these mineral Chinese medicinals from fossil had their characteristics absorption so that they can be quickly and accurately differentiated from each other through pattern recognition method. It was concluded that based on near-infrared spectroscopic mod-eling, these mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs can be quickly and accurately identified.

Objective:To develop a qualitative analysis model for the fast identification of Dens Draconis and its adulterants by NIR correlation coefficient method. Methods:On the basis of the traditional morphological identification, the spectra were collected u-sing the fiber accessory of a near-infrared spectroradiometer. The reference spectra were set up using the NIR spectra of certified Dens Draconis. The characteristic spectral section was chosen and the appropriate threshold was set to establish a qualitative analysis model for the rapid identification of Dens Draconis and its adulterant. Results:The spectral section of 5 000-4 200 cm-1 was selected as the characteristic spectral section, the correlation coefficient of Dens Draconis and its adulterant was calculated in training set samples, and 92. 67% was used as the threshold. Totally 10 batches of validation set samples were validated the qualitative analysis model, and the prediction accuracy was 90%. Conclusion:The method has good prediction ability, and can be used in the rapid identification of Dens Draconis and its adulterant.

Objective To observe the effect of yang-supplementing moxibustion in improving the muscular spasm, motor function, and activities of daily living (ADL) of patients with post-stroke hemiplegia.Method Totally 120 patients with post-stroke limb spasm due to qi deficiency and blood stagnation were randomized into group A, B, and C, 40 cases in each group. Group C was intervened by conventional treatment, group A was by yang-supplementing moxibustion in addition to the conventional treatment, and group B was by fire therapy in addition to the conventional treatment. The modified Ashworth Scale (MAS), Fugl-Meyer Scale (FMS), and Barthel Index (BI) were observed before and after intervention.Result Respectively after 1-month and 2-month treatment, the MAS, FMS, and BI scores were significantly different from that before intervention in the 3 groups (P<0.01). After 1-month and 2-month treatment, the MAS, FMS, and BI scores in group A were significantly different from that in group B and group C (P<0.05), and the scores in group B were significantly different from that in group C (P<0.05).Conclusion Yang-supplementing moxibustion can effectively improve the post-stroke limb spasm, and can promote the recovery of motor function.

The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

Objective:To examine metastatic gastric cancer patients who underwent surgery after chemotherapy and to determine the factors affecting survival. Methods:Clinical data on metastatic gastric cancer patients who underwent surgery after chemotherapy were retrospectively analyzed. The overall survival data were evaluated through the Kaplan-Meier method, Log-rank test, and Cox haz-ards regression. Results:The median age was 46 (22~74), and the median overall survival rate (OS) was 19 months (4~59 months). Response to chemotherapy (23.0 m for PR and 14.5 m for SD, P=0.045) and resection of the primary tumor (23.0 and 5.5 m, respective-ly, P=0.017) affected OS. No single factor was related to OS according to Cox regression. Conclusion:Surgical removal of the primary tumor is recommended for metastatic gastric cancer patients with positive response to chemotherapy and with a primary tumor that can be resected.

Objective To modify the method of gavage administration in guinea pigs. Methods Fourty awake guinea pigs were kept rearing on the hind legs and leaning on a vertical fixture to avoid their escaping forward. A 1 mL injector was inserted into the mouth to the depth when the molar teeth were passed. Another fourty guinea pigs under general anesthesia were reversed at trendelenburg position and a children suction tube with an outer diameter of 2 mm was inserted into the stomach. Results All of the 80 guinea pigs were administered by modified gavage smoothly for seven consecutive days by one operator each time. None endured much pain or digestive tract injury, or died from air way perfusion by mistake. Conclusions We successfully modified the gavage method in guinea pigs, which would definitely take guinea pigs involved in intragastical pharmacal experiments besides the routine of rats and mice.

OBJECTIVETo explore the influence of two different endolymphatic infusion ways on cochlear morphology and function.

METHODSForty healthy pigment guinea pigs (250 - 350 g) with normal Prey's reflex were divided into A and B group with 20 animals respectively. The right ears served as treated ears and the left ones as control ones. In group A, 5 microl of adenovirus 5-enhanced green fluorescence protein (Ad5-EGFP) suspension was infused into the scala media through an opened cochleostomy on the lateral wall of the scala media (LWS). In group B, the same volume of Ad5-EGFP suspension was infused into the scala media through punctured round window membrane and the basilar membrane (RBM). Cochlear morphology was examined under scan electric microscope and phalloidin staining was used to observe the hair cells in the infused ears after the animals were sacrificed. Auditory brainstem thresholds of the ears of all the animals were measured before and after treatment.

RESULTSAll the animals recovered well after operation. The holes on the lateral wall of the scala media and punctures on the round window membrane were healed completely. EGFP labeling appeared in the organ of Corti and lining wall of the stria vascularis indicated that adenovirus suspension was injected into the scala media using LWS (succeed in 14 animals accounted for 70%) and RBM (in 8 animals accounted for 40%) ways. Viruses were inoculated into the scala media with only locally inflammation reaction. In group A the hearing threshold decreased significantly in the treated ears compared with the control ears after the operation [(33.1+/-10.3) dB, (9.4+/-3.9) dB, F=46.34, P=0.0005]. However, in group B there was no significantly different between the treated ears and the control ears after the operation [(2.5+/-3.8) dB, (2.5+/-3.8) dB, F=0.00, P=1.000]. Phalloidin staining indicated that in group A the extension of hair cells loss was bigger than in group B. In some animals of two groups, EGFP labeling appeared in the extra-lymphatic system indicating that some of the injected suspension leaked out of the scala media.

CONCLUSIONSAd5-EGFP could be infused into the scala media through LWS or RBM and adenovirus could infect the lining cells of scala media and supporting cells in the basal membrane successfully without causing immunoreaction in the whole cochlea. LWS caused more hair cell loss and hearing loss than RBM. However, the cochlear morphology could be recovered completely after surgery. The positive inoculation rate was relatively higher that through LWS than that through RBM.

OBJECTIVETo introduce the diagnosis and the treatment of the long-segment bowel stenosis above the anastomosis and bowel obstruction caused by the radiation-induced pelvic wall and bowel fibrosis.

METHODSBetween January 2008 and June 2014, 468 patients with rectal carcinoma underwent sphincter-preserving operation after neoadjuvant chemoradiotherapy in Fujian Medical University Union Hospital. Among 241 patients without postoperative anastomotic leakage, anastomosis stenosis, local recurrence and small bowel obstruction, severe pelvic and bowel fibrosis with obstruction during follow-up was found in 14 patients(SFO group). Associated data of these 14 patients were retrospectively collected. Clinical and image characteristics, and treatment outcomes of these 14 patients were analyzed and compared to those of other 227 patients without fibrosis and obstruction (control group).

RESULTSCompared to control group, SFO group had lower BMI(19.7±2.3 vs. 22.5±3.2, P=0.000), higher ratio of male (92.9% vs. 63.9%, P=0.039) and smoking patients(78.6% vs. 32.2%, P=0.001), shorter preoperative distance from lower edge of tumor to anal verge [(4.9±0.7) cm vs. (5.7±1.4) cm, P=0.043), and longer time from the end of radiation to operation [(9.4±2.3) week vs. (8.1±1.7) week, P=0.024). The largest thickness of the bilateral obturator internus increased significantly after chemoradiotherapy (left side: P=0.030, right side: P=0.020) as compared to pre-chemoradiotherapy on MR image. Patients of SFO group received corresponding treatments according to the status of bowel stricture, and the outcomes were all satisfactory.

CONCLUSIONSReconstructed rectum stricture can be caused by the radiation-induced fibrosis of pelvic wall soft tissue and proximal colon. Severe stricture can be treated with corresponding methods to relieve symptoms.

Objective: To understand the longitudinal changes of refractive errors in adolescent myopia screening in the suburb of Shanghai, and to provide reference for targeted measures of myopia prevention and intervention. Methods: By using the cluster sampling method, 1 346 students were selected from two primary schools in a town in the suburb of Shanghai. Physical development indicators and refractive examination parameters of non ciliary muscle paralysis, and uncorrected visual acuity in 2017 and 2020 were collected from the Shanghai adolescent refractive development file. Longitudinal change of spherical equivalent (SE) refractive were assessed. A linear regression model was used to examine the relationship between the rate of SE change with characteristics of the students. Results: The average annual incidence of myopia was 16.36%, and the SE degrees of the left and right eyes of myopia students decreased by 225 degrees for three years. Girls (right eye Z=-4.33; left eye Z=-3.75, P<0.01), newly-onset myopia and persistent myopia (right eye Z=634.45; left eye Z=638.85, P<0.01) was a key for the rapid progress of refractive power. Conclusion The proportion of students with severe low vision is relatively high, and the apparent shifts toward more hyperopia in myopia students call for effective prevention and control programs based on changes in refractive to slow the progression of adolescent myopia.

Objective To investigate the efficacy of scalp acupuncture with strong stimulation plus oral hiccup decoction in treating intractable hiccup. Method One hundred patients with intractable hiccup were allocated, using a random number table, to treatment and control groups, 50 cases each. In addition to oral hiccup decoction in the two groups, the treatment group received scalp acupuncture with strong stimulation at the stomach and chest areas and the control group, electroacupuncture, for two courses of treatment. The times to produce the effect and the symptom frequency scores were compared between the two groups. Result After one course of treatment, the cure rate, the cure and marked efficacy rate and the total efficacy rate were 42％, 66％ and 78％, respectively, in the treatment group and 24％, 40％ and 68％, respectively, in the control group. There were statistically significant difference in the cure rate and the cure and marked efficacy rate (P<0.05) but no in the total efficacy rate (P>0.05) between the two groups. After two courses of treatment, the cure rate, the cure and marked efficacy rate and the total efficacy rate were 68％, 78％ and 88％, respectively, in the treatment group and 40％, 60％ and 74％, respectively, in the control group. There were statistically significant difference in the cure rate (P<0.05) but no in the cure and marked efficacy rate and the total efficacy rate (P>0.05) between the two groups. After one and two courses of treatment, there was a statistically significant difference in the hiccup frequency score between the treatment and control groups (P<0.05). The time to produce the effect was 2-5 hrs in the treatment group and 5-8 hrs in the control group. Conclusion The total efficacy rate of scalp acupuncture with strong stimulation for intractable hiccup is not significantly different from that of electroacupuncture, but the cure rate of the former was significantly higher than that of the latter. Scalp acupuncture with strong stimulation can produce a quick effect, reduce the frequency of hiccups and relieve symptoms accompanying hiccup.
